I usually use sys.platform (docs) to get the platform. sys.platform will distinguish between linux, other unixes, and OS X, while os.name is "posix" for all of them.

For much more detailed information, use the platform module. This has cross-platform functions that will give you information on the machine architecture, OS and OS version, version of Python, etc. Also it has os-specific functions to get things like the particular linux distribution.

Assuming that yourObject.toString() returns "true" or "false", you can try

boolean b = Boolean.valueOf(yourObject.toString())

A little late to the game here, but I was running into some performance issues with HYRY's solution, so I had to come up with another one.

It works by finding the frequency of each key-value, and then, for each key, only keeping the value that appears with it most often.

There's also an additional solution that supports multiple modes.

On a scale test that's representative of the data I'm working with, this reduced runtime from 37.4s to 0.5s!

Here's the code for the solution, some example usage, and the scale test:

import numpy as np
import pandas as pd
import random
import time

test_input = pd.DataFrame(columns=[ 'key',          'value'],
                          data=  [[ 1,              'A'    ],
                                  [ 1,              'B'    ],
                                  [ 1,              'B'    ],
                                  [ 1,              np.nan ],
                                  [ 2,              np.nan ],
                                  [ 3,              'C'    ],
                                  [ 3,              'C'    ],
                                  [ 3,              'D'    ],

This question has got 91,000 views so perhaps many people are looking for a more generic solution to the issue in the title "error converting varchar to INT"

If you are on SQL Server 2012+ one way of handling this invalid data is to use TRY_CAST

SELECT TRY_CAST (userID AS INT)
FROM   audit 

On previous versions you could use

SELECT CASE
         WHEN ISNUMERIC(RTRIM(userID) + '.0e0') = 1
              AND LEN(userID) <= 11
           THEN CAST(userID AS INT)
       END
FROM   audit 

Both return NULL if the value cannot be cast.

In the specific case that you have in your question with known bad values I would use the following however.

CAST(REPLACE(userID COLLATE Latin1_General_Bin, CHAR(0),'') AS INT)

Trying to replace the null character is often problematic except if using a binary collation.

This is NOT possible

The Simulator does not run ARM code, ONLY x86 code. Unless you have the raw source code from Apple, you won't see the App Store on the Simulator.

The app you write you will be able to test in the Simulator by running it directly from Xcode even if you don't have a developer account. To test your app on an actual device, you will need to be apart of the Apple Developer program.

I had this problem with a Nexus 7 - it appeared in Device Manager fine but wasn't recognised by Android Studio. The device had USB debugging turned on. Eventually I noticed an icon in the top left hand corner that said "Connected as a media device. Touch for other USB options." When I selected this I was able to change from Media Device (MTP) to Camera (PTP) and then it started working.

Update version

Objective-C

Create:

NSDictionary *dictionary = @{@"myKey1": @7, @"myKey2": @5}; 

Change:

NSMutableDictionary *mutableDictionary = [dictionary mutableCopy];     //Make the dictionary mutable to change/add
mutableDictionary[@"myKey3"] = @3;

The short-hand syntax is called Objective-C Literals.

Swift

Create:

var dictionary = ["myKey1": 7, "myKey2": 5]

Change:

dictionary["myKey3"] = 3

seems like in Angular 1.3.12 you do not need the inner ng-repeat anymore, the outer loop returns the values of the collection is a single map entry

No, there is no "easy" way. Your best bet would be to do a loop where you first check each previous sibling, then move to the parent node and all of its previous siblings.

You'll need to break the selector into two, 1 to check if the current node could be the top level node in your selector, and 1 to check if it's descendants match.

Edit: This might as well be a plugin. You can use this with any selector in any HTML:

(function($) {
    $.fn.closestPrior = function(selector) {
        selector = selector.replace(/^\s+|\s+$/g, "");
        var combinator = selector.search(/[ +~>]|$/);
        var parent = selector.substr(0, combinator);
        var children = selector.substr(combinator);
        var el = this;
        var match = $();
        while (el.length && !match.length) {
            el = el.prev();
            if (!el.length) {
                var par = el.parent();
                // Don't use the parent - you've already checked all of the previous 
                // elements in this parent, move to its previous sibling, if any.
                while (par.length && !par.prev().length) {
                    par = par.parent();
                }
                el = par.prev();
                if (!el.length) {
                    break;
                }
            }
            if (el.is(parent) && el.find(children).length) {
                match = el.find(children).last();
            }
            else if (el.find(selector).length) {
                match = el.find(selector).last();
            }
        }
        return match;
    }
})(jQuery);

If a class is declared as static then the variables and methods need to be declared as static.

A class can be declared static, indicating that it contains only static members. It is not possible to create instances of a static class using the new keyword. Static classes are loaded automatically by the .NET Framework common language runtime (CLR) when the program or namespace containing the class is loaded.

Use a static class to contain methods that are not associated with a particular object. For example, it is a common requirement to create a set of methods that do not act on instance data and are not associated to a specific object in your code. You could use a static class to hold those methods.

->The main features of a static class are:

• They only contain static members.
• They cannot be instantiated.
• They are sealed.
• They cannot contain Instance Constructors or simply constructors as we know that they are associated with objects and operates on data when an object is created.

Example

static class CollegeRegistration
{
  //All static member variables
   static int nCollegeId; //College Id will be same for all the students studying
   static string sCollegeName; //Name will be same
   static string sColegeAddress; //Address of the college will also same

    //Member functions
   public static int GetCollegeId()
   {
     nCollegeId = 100;
     return (nCollegeID);
   }
    //similarly implementation of others also.
} //class end


public class student
{
    int nRollNo;
    string sName;

    public GetRollNo()
    {
       nRollNo += 1;
       return (nRollNo);
    }
    //similarly ....
    public static void Main()
   {
     //Not required.
     //CollegeRegistration objCollReg= new CollegeRegistration();

     //<ClassName>.<MethodName>
     int cid= CollegeRegistration.GetCollegeId();
    string sname= CollegeRegistration.GetCollegeName();


   } //Main end
}

Go to File-> Project Structure-> Libraries and click green "+" to add the directory folder that has the JARs to CLASSPATH. Everything in that folder will be added to CLASSPATH.

Update:

It's 2018. It's a better idea to use a dependency manager like Maven and externalize your dependencies. Don't add JAR files to your project in a /lib folder anymore.

After copy values from Google web UI, I had a blank space for:

• client_id
• secret

And at the BEGINNING and at the END for both.

You just have to reset the values you don't want to their defaults. No need to get into a mess by using !important.

#zoomTarget .slikezamenjanje img {
    max-height: auto;
    padding-right: 0px;
}

Hatting

I think the key datum you are missing is that CSS comes with default values. If you want to override a value, set it back to its default, which you can look up.

For example, all CSS height and width attributes default to auto.

You can't just change the delimiters from ---- BEGIN SSH2 PUBLIC KEY ---- to -----BEGIN RSA PUBLIC KEY----- and expect that it will be sufficient to convert from one format to another (which is what you've done in your example).

This article has a good explanation about both formats.

What you get in an RSA PUBLIC KEY is closer to the content of a PUBLIC KEY, but you need to offset the start of your ASN.1 structure to reflect the fact that PUBLIC KEY also has an indicator saying which type of key it is (see RFC 3447). You can see this using openssl asn1parse and -strparse 19, as described in this answer.

EDIT: Following your edit, your can get the details of your RSA PUBLIC KEY structure using grep -v -- ----- | tr -d '\n' | base64 -d | openssl asn1parse -inform DER:

    0:d=0  hl=4 l= 266 cons: SEQUENCE          
    4:d=1  hl=4 l= 257 prim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
  265:d=1  hl=2 l=   3 prim: INTEGER           :010001

To decode the SSH key format, you need to use the data format specification in RFC 4251 too, in conjunction with RFC 4253:

   The "ssh-rsa" key format has the following specific encoding:

      string    "ssh-rsa"
      mpint     e
      mpint     n

For example, at the beginning, you get 00 00 00 07 73 73 68 2d 72 73 61. The first four bytes (00 00 00 07) give you the length. The rest is the string itself: 73=s, 68=h, ... -> 73 73 68 2d 72 73 61=ssh-rsa, followed by the exponent of length 1 (00 00 00 01 25) and the modulus of length 256 (00 00 01 00 7f ...).

First, the error you're getting is due to where you're using the COUNT function -- you can't use an aggregate (or group) function in the WHERE clause.

Second, instead of using a subquery, simply join the table to itself:

SELECT a.pid 
FROM Catalog as a LEFT JOIN Catalog as b USING( pid )
WHERE a.sid != b.sid
GROUP BY a.pid

Which I believe should return only rows where at least two rows exist with the same pid but there is are at least 2 sids. To make sure you get back only one row per pid I've applied a grouping clause.

For single page, I just edited the answer of @Jack Humphries

-(void)viewDidLoad
{
  counter = 0;
}
-(IBAction)buttonClick:(id)sender
{
  counter++;
  DataViewController *secondVC = [self.modelController viewControllerAtIndex:counter storyboard:self.storyboard];
  NSArray *viewControllers = nil;          
  viewControllers = [NSArray arrayWithObjects:secondVC, nil];          
  [self.pageViewController setViewControllers:viewControllers direction:UIPageViewControllerNavigationDirectionForward animated:YES completion:NULL];
}

You can do something like:

get-content input_file1 > output_file
get-content input_file2 >> output_file

Where > is an alias for "out-file", and >> is an alias for "out-file -append".

Easy one! "\t"

Edit: In fact, here's something official: Escape Sequences

Another easy way to do it so that it is referenced in the project folder you want, like "Frameworks", is to:

1. Select "Show the Project navigator"
2. Right-click on the project folder you wish to add the framework to.
3. Select 'Add Files to "YourProjectName"'
4. Browse to the framework - generally under /Developer/SDKs/MacOSXversion.sdk/System/Library/Frameworks
5. Select the one you want.
6. Select "Add"

It will appear in both the project navigator where you want it, as well as in the "Link Binary With Libraries" area of the "Build Phases" pane of your target.

You have to repeat your expression everywhere you want to use it:

SELECT Replace(Postcode, ' ', '') AS P
FROM Contacts
WHERE Replace(Postcode, ' ', '') LIKE 'NW101%'

or you can make it a subquery

select P
from (
SELECT Replace(Postcode, ' ', '') AS P
FROM Contacts
) t
WHERE P LIKE 'NW101%'

"Headers already sent" means that your PHP script already sent the HTTP headers, and as such it can't make modifications to them now.

Check that you don't send ANY content before calling session_start. Better yet, just make session_start the first thing you do in your PHP file (so put it at the absolute beginning, before all HTML etc).

if (openFileDialog1.ShowDialog(this) == DialogResult.OK)

    strfilename = openFileDialog1.InitialDirectory + openFileDialog1.FileName;

== is an operator. equals is a method defined in the Object class

== checks if two objects have the same address in the memory and for primitive it checks if they have the same value.equals method on the other hand checks if the two objects which are being compared have an equal value(depending on how ofcourse the equals method has been implemented for the objects. equals method cannot be applied on primitives(which means that if a is a primitive a.equals(someobject) is not allowed, however someobject.equals(a) is allowed).

You don't need to create a button. The facility exists by default.

Just right click on the arrow buttons on the bottom left hand corner of the Excel window. These are the arrow buttons which if you left click move left or right one worksheet.

If you right-click on these arrows Excel will pop up a dialogue with a list of worksheets from which you can click to set your chosen sheet active.

You can use the ES6 Destructuring Assignment feature with a rest operator. A comma indicates where you want to remove the element and the rest (...arr) operator to give you the remaining elements of the array.

}_x000D_
const arr = removeFirst(source);_x000D_
console.log(arr); // [2, 3, 5, 6]_x000D_

Sounds like you're overextending regex for this purpose. What I would do is use a regex to match a few date formats and then use a separate function to validate the values of the date fields so extracted.

When and where to use \\\" instead. OK if you are like me you will feel just as silly as I did when I realized what I was doing after I found this thread.

If you're making a .json text file/stream and importing the data from there then the main stream answer of just one backslash before the double quotes:\" is the one you're looking for.

However if you're like me and you're trying to get the w3schools.com "Tryit Editor" to have a double quotes in the output of the JSON.parse(text), then the one you're looking for is the triple backslash double quotes \\\". This is because you're building your text string within an HTML <script> block, and the first double backslash inserts a single backslash into the string variable then the following backslash double quote inserts the double quote into the string so that the resulting script string contains the \" from the standard answer and the JSON parser will parse this as just the double quotes.

<script>
  var text="{";
  text += '"quip":"\\\"If nobody is listening, then you\'re likely talking to the wrong audience.\\\""';
  text += "}";
  var obj=JSON.parse(text);
</script>

+1: since it's a JavaScript text string, a double backslash double quote \\" would work too; because the double quote does not need escaped within a single quoted string eg '\"' and '"' result in the same JS string.

In my case, the folder ProgramData was hidden by default on windows 7, so I was unable to find my.ini file.

After selecting show hidden files and folders option, I was able to find the my.ini file at the location: C:\ProgramData\MySQL\MySQL Server 5.6.

Display hidden files and folders on windows 7:

1. Right-click the Windows Logo button and choose Open Windows Explorer.

2. Click Organize and choose Folder and Search Options.

3. Click the View tab, select Show hidden files and folders and then clear the checkbox for Hide protected system operating files.

4. Click Yes on the warning and then click OK.

check out my js lib for caching: https://github.com/hoangnd25/cacheJS

My blog post: New way to cache your data with Javascript

Features:

• Conveniently use array as key for saving cache
• Support array and localStorage
• Clear cache by context (clear all blog posts with authorId="abc")
• No dependency

Basic usage:

Saving cache:

cacheJS.set({blogId:1,type:'view'},'<h1>Blog 1</h1>');
cacheJS.set({blogId:2,type:'view'},'<h1>Blog 2</h1>', null, {author:'hoangnd'});
cacheJS.set({blogId:3,type:'view'},'<h1>Blog 3</h1>', 3600, {author:'hoangnd',categoryId:2});

Retrieving cache:

cacheJS.get({blogId: 1,type: 'view'});

Flushing cache

cacheJS.removeByKey({blogId: 1,type: 'view'});
cacheJS.removeByKey({blogId: 2,type: 'view'});

cacheJS.removeByContext({author:'hoangnd'});

Switching provider

cacheJS.use('array');
cacheJS.use('array').set({blogId:1},'<h1>Blog 1</h1>')};

Your regex should work 'as-is'. Assuming that it is doing what you want it to.

wordA(\s*)wordB(?! wordc)

This means match wordA followed by 0 or more spaces followed by wordB, but do not match if followed by wordc. Note the single space between ?! and wordc which means that wordA wordB wordc will not match, but wordA wordB wordc will.

Here are some example matches and the associated replacement output:

Note that all matches are replaced no matter how many spaces. There are a couple of other points: -

• (?! wordc) is a negative lookahead, so you wont match lines wordA wordB wordc which is assume is intended (and is why the last line is not matched). Currently you are relying on the space after ?! to match the whitespace. You may want to be more precise and use (?!\swordc). If you want to match against more than one space before wordc you can use (?!\s*wordc) for 0 or more spaces or (?!\s*+wordc) for 1 or more spaces depending on what your intention is. Of course, if you do want to match lines with wordc after wordB then you shouldn't use a negative lookahead.

• * will match 0 or more spaces so it will match wordAwordB. You may want to consider + if you want at least one space.

• (\s*) - the brackets indicate a capturing group. Are you capturing the whitespace to a group for a reason? If not you could just remove the brackets, i.e. just use \s.

Update based on comment

Hello the problem is not the expression but the HTML out put   that are not considered as whitespace. it's a Joomla website.

Preserving your original regex you can use:

wordA((?:\s| )*)wordB(?!(?:\s| )wordc)

The only difference is that not the regex matches whitespace OR  . I replaced wordc with \swordc since that is more explicit. Note as I have already pointed out that the negative lookahead ?! will not match when wordB is followed by a single whitespace and wordc. If you want to match multiple whitespaces then see my comments above. I also preserved the capture group around the whitespace, if you don't want this then remove the brackets as already described above.

Example matches:

If you do not want to use jQuery in the solution you could try this. Solution nabbed from here https://stackoverflow.com/a/1714899/1784301

$http({
    method: 'POST',
    url: url,
    headers: {'Content-Type': 'application/x-www-form-urlencoded'},
    transformRequest: function(obj) {
        var str = [];
        for(var p in obj)
        str.push(encodeURIComponent(p) + "=" + encodeURIComponent(obj[p]));
        return str.join("&");
    },
    data: xsrf
}).success(function () {});

Tag ids must be unique. You are updating the span with ID 'ItemCostSpan' of which there are two. Give the span a class and get it using find.

    $("legend").each(function() {
        var SoftwareItem = $(this).text();
        itemCost = GetItemCost(SoftwareItem);
        $("input:checked").each(function() {               
            var Component = $(this).next("label").text();
            itemCost += GetItemCost(Component);
        });            
        $(this).find(".ItemCostSpan").text("Item Cost = $ " + itemCost);
    });

osascript -e "tell application \"System Events\" to keystroke \"w\" using command down"

This simulates a CMD + w keypress.

If you want Terminal to quit completely you can use: osascript -e "tell application \"System Events\" to keystroke \"q\" using command down"

This doesn't give any errors and makes the Terminal stop cleanly.

Link with -static. When you link with -static the linker embeds the library inside the executable, so the executable will be bigger, but it can be executed on a system with an older version of glibc because the program will use it's own library instead of that of the system.

You could create a wrapper application that you run instead of directly running your real app. The wrapper application can listen to stdout and redirect everything to Trace. Then change the run settings to launch your wrapper and pass in the path to the real app to run.

You could also have the wrapper auto-attach the debugger to the new process if a debugger is attached to the wrapper.

It only works till 4000 byte, What if the clob is bigger than 4000 bytes then we use this

declare
v_clob_size clob;

begin

      v_clob_size:= (DBMS_LOB.getlength(v_clob)) / 1024 / 1024;
      DBMS_OUTPUT.put_line('CLOB Size   ' || v_clob_size);   
end;

or

select (DBMS_LOB.getlength(your_column_name))/1024/1024 from your_table

When i need to copy data from filtered table i use range.SpecialCells(xlCellTypeVisible).copy. Where the range is range of all data (without a filter).

Example:

Sub copy()
     'source worksheet
     dim ws as Worksheet
     set ws = Application.Worksheets("Data")' set you source worksheet here
     dim data_end_row_number as Integer
     data_end_row_number = ws.Range("B3").End(XlDown).Row.Number
    'enable filter
    ws.Range("B2:F2").AutoFilter Field:=2, Criteria1:="hockey", VisibleDropDown:=True
    ws.Range("B3:F" & data_end_row_number).SpecialCells(xlCellTypeVisible).Copy
    Application.Worksheets("Hoky").Range("B3").Paste
    'You have to add headers to Hoky worksheet
end sub

This should give you a list of all the tables in your database

SELECT Distinct TABLE_NAME FROM information_schema.TABLES

So you can use it similar to your database check.

If NOT EXISTS(SELECT Distinct TABLE_NAME FROM information_schema.TABLES Where TABLE_NAME = 'Your_Table')
BEGIN
    --CREATE TABLE Your_Table
END
GO

I had a similar problem, trying to add a background image with inline css. No need to specify the images folder due to the way asset sync works.

This worked for me:

background-image: url('/assets/image.jpg');

Quick comparison of timings in response to the post by Abbafei:

import timeit

def func1():
    phrase = 'Lucky Dog'
    return any(i in 'LD' for i in phrase)

def func2():
    phrase = 'Lucky Dog'
    if ('L' in phrase) or ('D' in phrase):
        return True
    else:
        return False

if __name__ == '__main__': 
    func1_time = timeit.timeit(func1, number=100000)
    func2_time = timeit.timeit(func2, number=100000)
    print('Func1 Time: {0}\nFunc2 Time: {1}'.format(func1_time, func2_time))

Output:

Func1 Time: 0.0737484362111
Func2 Time: 0.0125144964371

So the code is more compact with any, but faster with the conditional.

EDIT : TL;DR -- For long strings, if-then is still much faster than any!

I decided to compare the timing for a long random string based on some of the valid points raised in the comments:

# Tested in Python 2.7.14

import timeit
from string import ascii_letters
from random import choice

def create_random_string(length=1000):
    random_list = [choice(ascii_letters) for x in range(length)]
    return ''.join(random_list)

def function_using_any(phrase):
    return any(i in 'LD' for i in phrase)

def function_using_if_then(phrase):
    if ('L' in phrase) or ('D' in phrase):
        return True
    else:
        return False

if __name__ == '__main__':
    random_string = create_random_string(length=2000)
    func1_time = timeit.timeit(stmt="function_using_any(random_string)",
                               setup="from __main__ import function_using_any, random_string",
                               number=200000)
    func2_time = timeit.timeit(stmt="function_using_if_then(random_string)",
                               setup="from __main__ import function_using_if_then, random_string",
                               number=200000)
    print('Time for function using any: {0}\nTime for function using if-then: {1}'.format(func1_time, func2_time))

Output:

Time for function using any: 0.1342546
Time for function using if-then: 0.0201827

If-then is almost an order of magnitude faster than any!

If you cannot use spark-csv, you can do the following:

df.rdd.map(lambda x: ",".join(map(str, x))).coalesce(1).saveAsTextFile("file.csv")

If you need to handle strings with linebreaks or comma that will not work. Use this:

import csv
import cStringIO

def row2csv(row):
    buffer = cStringIO.StringIO()
    writer = csv.writer(buffer)
    writer.writerow([str(s).encode("utf-8") for s in row])
    buffer.seek(0)
    return buffer.read().strip()

df.rdd.map(row2csv).coalesce(1).saveAsTextFile("file.csv")

Stored procedure can be called recursively but stored function can not

Always use

//Super Fast
$('#my_id').find('.my_class'); 

instead of

// Fast:
$('#my_id .my_class');

Have look at JQuery Performance Rules.

Also at Jquery Doc

To hide from the UI, use Format > Sheet > Hide

To hide programatically, use the Visible property of the Worksheet object. If you do it programatically, you can set the sheet as "very hidden", which means it cannot be unhidden through the UI.

ActiveWorkbook.Sheets("Name").Visible = xlSheetVeryHidden 
' or xlSheetHidden or xlSheetVisible

You can also set the Visible property through the properties pane for the worksheet in the VBA IDE (ALT+F11).

It is possible to use apache commons (commons-lang3) and its DurationFormatUtils class.

<dependency>
  <groupId>org.apache.commons</groupId>
  <artifactId>commons-lang3</artifactId>
  <version>3.1</version>
</dependency>

For example:

String formattedDuration = DurationFormatUtils.formatDurationHMS(12313152);
// formattedDuration value is "3:25:13.152"
String otherFormattedDuration = DurationFormatUtils.formatDuration(12313152, DurationFormatUtils.ISO_EXTENDED_FORMAT_PATTERN);
// otherFormattedDuration value is "P0000Y0M0DT3H25M13.152S"

Hope it can help ...

I used setLogLevel(LogLevel.FULL).setLog(new AndroidLog("YOUR_LOG_TAG")), it helped me.
UPDATE.
You can also try for debug purpose use retrofit.client.Response as response model

This works in Mac as well you can use

df= pd.read_csv('Region_count.csv', encoding ='latin1')

Everyone else has posted "going backwards" answer, so I'll give the alternative: create a list of items you want to remove, then remove them at the end:

List<string> removals = new List<string>();
foreach (string s in listBox1.Items)
{
    MessageBox.Show(s);
    //do stuff with (s);
    removals.Add(s);
}

foreach (string s in removals)
{
    listBox1.Items.Remove(s);
}

Sometimes the "work backwards" method is better, sometimes the above is better - particularly if you're dealing with a type which has a RemoveAll(collection) method. Worth knowing both though.

Using Guid would be a pretty good way, but to get something looking like your example, you probably want to convert it to a Base64 string:

    Guid g = Guid.NewGuid();
    string GuidString = Convert.ToBase64String(g.ToByteArray());
    GuidString = GuidString.Replace("=","");
    GuidString = GuidString.Replace("+","");

I get rid of "=" and "+" to get a little closer to your example, otherwise you get "==" at the end of your string and a "+" in the middle. Here's an example output string:

"OZVV5TpP4U6wJthaCORZEQ"

One reason for using non-standard checkbox serialization that isn't addressed in the question or in of the current answers is to only deserialize (change) fields that were explicitly specified in the serialized data - e.g. when you are using jquery serialization and deserialization to/from a cookie to save and load prefererences.

Thomas Danemar implemented a modification to the standard serialize() method to optionally take a checkboxesAsBools option: http://tdanemar.wordpress.com/2010/08/24/jquery-serialize-method-and-checkboxes/ - this is similar to the implementation listed above by @mydoghasworms, but also integrated into the standard serialize.

I've copied it to Github in case anyone has improvements to make at any point: https://gist.github.com/1572512

Additionally, the "jquery.deserialize" plugin will now correctly deserialize checkbox values serialized with checkboxesAsBools, and ignore checkboxes that are not mentioned in the serialized data: https://github.com/itsadok/jquery.deserialize

I had ETIMEDOUT error, and after putting

{
  "proxy":"http://<user>:<password>@<host>:<port>",
  "https-proxy":"http://<user>:<password>@<host>:<port>"

just worked. I don't know if you have something wrong in the .bowerrc or ECONNRESET can't be solved with this, but I hope this help you ;)

Use a DateFormat implementation; e.g. SimpleDateFormat.

DateFormat df = new SimpleDateFormat("dd/MM/yyyy");
String data = df.format(new Date());

Postgres hasn't implemented an equivalent to INSERT OR REPLACE. From the ON CONFLICT docs (emphasis mine):

It can be either DO NOTHING, or a DO UPDATE clause specifying the exact details of the UPDATE action to be performed in case of a conflict.

Though it doesn't give you shorthand for replacement, ON CONFLICT DO UPDATE applies more generally, since it lets you set new values based on preexisting data. For example:

INSERT INTO users (id, level)
VALUES (1, 0)
ON CONFLICT (id) DO UPDATE
SET level = users.level + 1;

select DateAdded, count(CustID)
from tbl
group by DateAdded

@Autowired annotation is defined in the Spring framework.

@Inject annotation is a standard annotation, which is defined in the standard "Dependency Injection for Java" (JSR-330). Spring (since the version 3.0) supports the generalized model of dependency injection which is defined in the standard JSR-330. (Google Guice frameworks and Picocontainer framework also support this model).

With @Inject can be injected the reference to the implementation of the Provider interface, which allows injecting the deferred references.

Annotations @Inject and @Autowired- is almost complete analogies. As well as @Autowired annotation, @Inject annotation can be used for automatic binding properties, methods, and constructors.

In contrast to @Autowired annotation, @Inject annotation has no required attribute. Therefore, if the dependencies will not be found - will be thrown an exception.

There are also differences in the clarifications of the binding properties. If there is ambiguity in the choice of components for the injection the @Named qualifier should be added. In a similar situation for @Autowired annotation will be added @Qualifier qualifier (JSR-330 defines it's own @Qualifier annotation and via this qualifier annotation @Named is defined).

I used pyplot's axes object to manually adjust the sizes without using GridSpec:

import matplotlib.pyplot as plt
import numpy as np
x = np.arange(0, 10, 0.2)
y = np.sin(x)

# definitions for the axes
left, width = 0.07, 0.65
bottom, height = 0.1, .8
bottom_h = left_h = left+width+0.02

rect_cones = [left, bottom, width, height]
rect_box = [left_h, bottom, 0.17, height]

fig = plt.figure()

cones = plt.axes(rect_cones)
box = plt.axes(rect_box)

cones.plot(x, y)

box.plot(y, x)

plt.show()

length variable:

In Java, array (not java.util.Array) is a predefined class in the language itself. To find the elements of an array, designers used length variable (length is a field member in the predefined class). They must have given length() itself to have uniformity in Java; but did not. The reason is by performance, executing length variable is speedier than calling the method length(). It is like comparing two strings with == and equals(). equals() is a method call which takes more time than executing == operator.

size() method:

It is used to find the number of elements present in collection classes. It is defined in java.util.Collection interface.

For Swift 3, many Foundation types have dropped the 'NS' prefix, so you'd access it by UUID().uuidString.

You can use izip to combine your lists, and then iterate them

for val in itertools.izip(l1,l2,l3,l4,l5):
    writer.writerow(val)

Here's yet another way, using pure NumPy, no recursion, no list comprehension, and no explicit for loops. It's about 20% slower than the original answer, and it's based on np.meshgrid.

def cartesian(*arrays):
    mesh = np.meshgrid(*arrays)  # standard numpy meshgrid
    dim = len(mesh)  # number of dimensions
    elements = mesh[0].size  # number of elements, any index will do
    flat = np.concatenate(mesh).ravel()  # flatten the whole meshgrid
    reshape = np.reshape(flat, (dim, elements)).T  # reshape and transpose
    return reshape

For example,

x = np.arange(3)
a = cartesian(x, x, x, x, x)
print(a)

gives

[[0 0 0 0 0]
 [0 0 0 0 1]
 [0 0 0 0 2]
 ..., 
 [2 2 2 2 0]
 [2 2 2 2 1]
 [2 2 2 2 2]]

Git is just trying to guess for you what you are trying to do. It is making every attempt to preserve unbroken history. Of course, it is not perfect. So git mv allows you to be explicit with your intention and to avoid some errors.

Consider this example. Starting with an empty repo,

git init
echo "First" >a
echo "Second" >b
git add *
git commit -m "initial commit"
mv a c
mv b a
git status

Result:

# On branch master
# Changes not staged for commit:
#   (use "git add/rm <file>..." to update what will be committed)
#   (use "git checkout -- <file>..." to discard changes in working directory)
#
#   modified:   a
#   deleted:    b
#
# Untracked files:
#   (use "git add <file>..." to include in what will be committed)
#
#   c
no changes added to commit (use "git add" and/or "git commit -a")

Autodetection failed :( Or did it?

    initial commit

Now try instead (remember to delete the .git folder when experimenting):

git init
echo "First" >a
echo "Second" >b
git add *
git commit -m "initial commit"
git mv a c
git status

So far so good:

# On branch master
# Changes to be committed:
#   (use "git reset HEAD <file>..." to unstage)
#
#   renamed:    a -> c


git mv b a
git status

Now, nobody is perfect:

# On branch master
# Changes to be committed:
#   (use "git reset HEAD <file>..." to unstage)
#
#   modified:   a
#   deleted:    b
#   new file:   c
#

Really? But of course...

git add *
git commit -m "change"
git log c
git log --follow c

...and the result is the same as above: only --follow shows the full history.

Now, be careful with renaming, as either option can still produce weird effects. Example:

git init
echo "First" >a
git add a
git commit -m "initial a"
echo "Second" >b
git add b
git commit -m "initial b"

git mv a c
git commit -m "first move"
git mv b a
git commit -m "second move"

git log --follow a

    second move

    initial b

Contrast it with:

git init
echo "First" >a
git add a
git commit -m "initial a"
echo "Second" >b
git add b
git commit -m "initial b"

git mv a c
git mv b a
git commit -m "both moves at the same time"

git log --follow a

Result:

commit 84bf29b01f32ea6b746857e0d8401654c4413ecd

    both moves at the same time

commit ec0de3c5358758ffda462913f6e6294731400455

Date:   Sat Oct 12 00:36:52 2013 -0400

    initial a

Ups... Now the history is going back to initial a instead of initial b, which is wrong. So when we did two moves at a time, Git became confused and did not track the changes properly. By the way, in my experiments the same happened when I deleted/created files instead of using git mv. Proceed with care; you've been warned...

I've answered that here: (WAMP/XAMP) send Mail using SMTP localhost (works not only GMAIL, but for others too).

For what its worth, installing a system app to the /system/app directory will be:

adb push appname.apk /system/app/

Just ensure you're in the right directory where the target .apk file to be installed is, or you could just copy the .apk file to the platform-tools directory of the Android SDK and adb would definitely find it.

Following are few libraries to create PDF with Java:

1. iText
2. Apache PDFBox
3. BFO

I have used iText for genarating PDF's with a little bit of pain in the past.

Or you can try using FOP: FOP is an XSL formatter written in Java. It is used in conjunction with an XSLT transformation engine to format XML documents into PDF.

On Nougat(7.0) Android version run adb shell pm list packages to list the packages installed on the device. Then run adb shell pm path your-package-name to show the path of the apk. After use adb to copy the package to Downloads adb shell cp /data/app/com.test-1/base.apk /storage/emulated/0/Download. Then pull the apk from Downloads to your machine by running adb pull /storage/emulated/0/Download/base.apk.

Use DateTime

$datetime = new DateTime('tomorrow');
echo $datetime->format('Y-m-d H:i:s');

Or:

$datetime = new DateTime('2013-01-22');
$datetime->modify('+1 day');
echo $datetime->format('Y-m-d H:i:s');

Or:

$datetime = new DateTime('2013-01-22');
$datetime->add(new DateInterval("P1D"));
echo $datetime->format('Y-m-d H:i:s');

Or in PHP 5.4+:

echo (new DateTime('2013-01-22'))->add(new DateInterval("P1D"))
                                 ->format('Y-m-d H:i:s');

If you want know, the how may nodejs processes running then you can use this command

ps -aef | grep node

So it will give list of nodejs process with it's project name. It will be helpful when you are running multipe nodejs application & you want kill specific process for the specific project.

Above command will give output like

XXX  12886  1741  1 12:36 ?        00:00:05 /home/username/.nvm/versions/node/v9.2.0/bin/node --inspect-brk=43443 /node application running path.

So to kill you can use following command

kill -9 12886

So it will kill the spcefic node process

var token = string.Empty;
if (Request.Headers.TryGetValue("MyKey",  out headerValues))
{
    token = headerValues.FirstOrDefault();
}

You could use the following code.

print_r($_SESSION);

You can use this method but it will work only if both the list are of the same size:

first = [1, 2, 3, 4, 5]
second = [6, 7, 8, 9, 10]
third = []

a = len(first)
b = int(0)
while True:
    x = first[b]
    y = second[b]
    ans = x + y
    third.append(ans)
    b = b + 1
    if b == a:
        break

print third

Suppose we have a dictionary like this

Dictionary<int,string> dict = new Dictionary<int, string>();
dict.Add(1, "Mohan");
dict.Add(2, "Kishor");
dict.Add(3, "Pankaj");
dict.Add(4, "Jeetu");

We can initialize it as follow.

Dictionary<int, string> dict = new Dictionary<int, string>  
{
    { 1, "Mohan" },
    { 2, "Kishor" },
    { 3, "Pankaj" },
    { 4, "Jeetu" }
};

You should use the following:

       <td><input id="priceInput-{{orderLine.id}}" type="number" [(ngModel)]="orderLine.price"></td>

You will need to add the FormsModule to your app.module in the inputs section as follows:

import { FormsModule } from '@angular/forms';

@NgModule({
  declarations: [
    ...
  ],
  imports: [
    BrowserModule,
    FormsModule
  ],
  ..

The use of the brackets around the ngModel are as follows:

• The [] show that it is taking an input from your TS file. This input should be a public member variable. A one way binding from TS to HTML.

• The () show that it is taking output from your HTML file to a variable in the TS file. A one way binding from HTML to TS.

• The [()] are both (e.g. a two way binding)

See here for more information: https://angular.io/guide/template-syntax

I would also suggest replacing id="priceInput-{{orderLine.id}}" with something like this [id]="getElementId(orderLine)" where getElementId(orderLine) returns the element Id in the TS file and can be used anywere you need to reference the element (to avoid simple bugs like calling it priceInput1 in one place and priceInput-1 in another. (if you still need to access the input by it's Id somewhere else)

The good part is we can make basic maths directly:

let nuts = 7_x000D_
_x000D_
more.innerHTML = `_x000D_
_x000D_
<h2>You collected ${nuts} nuts so far!_x000D_
_x000D_
<hr>_x000D_
_x000D_
Double it, get ${nuts + nuts} nuts!!_x000D_
_x000D_
`

<div id="more"></div>

It became really useful in a factory function:

function nuts(it){_x000D_
  return `_x000D_
    You have ${it} nuts! <br>_x000D_
    Cosinus of your nuts: ${Math.cos(it)} <br>_x000D_
    Triple nuts: ${3 * it} <br>_x000D_
    Your nuts encoded in BASE64:<br> ${btoa(it)}_x000D_
  `_x000D_
}_x000D_
_x000D_
nut.oninput = (function(){_x000D_
  out.innerHTML = nuts(nut.value)_x000D_
})

<h3>NUTS CALCULATOR_x000D_

• Handles nested objects and arrays
• Handles files
• Type support
• Tested in Chrome

const buildFormData = (formData: FormData, data: FormVal, parentKey?: string) => {
    if (isArray(data)) {
        data.forEach((el) => {
            buildFormData(formData, el, parentKey)
        })

    } else if (typeof data === "object" && !(data instanceof File)) {
        Object.keys(data).forEach((key) => {
            buildFormData(formData, (data as FormDataNest)[key], parentKey ? `${parentKey}.${key}` : key)
        })

    } else {
        if (isNil(data)) {
            return
        }

        let value = typeof data === "boolean" || typeof data === "number" ? data.toString() : data
        formData.append(parentKey as string, value)
    }
}

export const getFormData = (data: Record<string, FormDataNest>) => {
    const formData = new FormData()

    buildFormData(formData, data)

    return formData
}

Examples and Tests

const data = {
    filePhotos: imageArray,
}

yourAjaxCall({
   ...,
   data: getFormData(data)
})

Screenshot from Chrome dev tools - Network - Headers:

const data = {
    nested: {
        a: 1,
        b: ["hello", "world"],
        c: {
            d: 2,
            e: ["hello", "world"],
        }
    }
}

yourAjaxCall({
   ...,
   data: getFormData(data)
})

SHOW TABLES LIKE 'TableName'

If you have ANY results, the table exists.

To use this approach in PDO:

$pdo         = new \PDO(/*...*/);
$result      = $pdo->query("SHOW TABLES LIKE 'tableName'");
$tableExists = $result !== false && $result->rowCount() > 0;

To use this approach with DEPRECATED mysql_query

$result      = mysql_query("SHOW TABLES LIKE 'tableName'");
$tableExists = mysql_num_rows($result) > 0;

It is also possible to open the pdf link in a new window and let the browser handle the rest:

window.open(pdfUrl, '_blank');

or:

window.open(pdfUrl);

SQL

SQL is used to communicate with a database, it is the standard language for relational database management systems.

In detail Structured Query Language is a special-purpose programming language designed for managing data held in a relational database management system (RDBMS), or for stream processing in a relational data stream management system (RDSMS).

Originally based upon relational algebra and tuple relational calculus, SQL consists of a data definition language and a data manipulation language. The scope of SQL includes data insert, query, update and delete, schema creation and modification, and data access control. Although SQL is often described as, and to a great extent is, a declarative language (4GL), it also includes procedural elements.

PL/SQL

PL/SQL is a combination of SQL along with the procedural features of programming languages. It was developed by Oracle Corporation

Specialities of PL/SQL

• completely portable, high-performance transaction-processing language.
• provides a built-in interpreted and OS independent programming environment.
• directly be called from the command-line SQL*Plus interface.
• Direct call can also be made from external programming language calls to database.
• general syntax is based on that of ADA and Pascal programming language.
• Apart from Oracle, it is available in TimesTen in-memory database and IBM DB2.

T-SQL

Short for Transaction-SQL, an extended form of SQL that adds declared variables, transaction control, error and exceptionhandling and row processing to SQL

The Structured Query Language or SQL is a programming language that focuses on managing relational databases. SQL has its own limitations which spurred the software giant Microsoft to build on top of SQL with their own extensions to enhance the functionality of SQL. Microsoft added code to SQL and called it Transact-SQL or T-SQL. Keep in mind that T-SQL is proprietary and is under the control of Microsoft while SQL, although developed by IBM, is already an open format.

T-SQL adds a number of features that are not available in SQL.

This includes procedural programming elements and a local variable to provide more flexible control of how the application flows. A number of functions were also added to T-SQL to make it more powerful; functions for mathematical operations, string operations, date and time processing, and the like. These additions make T-SQL comply with the Turing completeness test, a test that determines the universality of a computing language. SQL is not Turing complete and is very limited in the scope of what it can do.

Another significant difference between T-SQL and SQL is the changes done to the DELETE and UPDATE commands that are already available in SQL. With T-SQL, the DELETE and UPDATE commands both allow the inclusion of a FROM clause which allows the use of JOINs. This simplifies the filtering of records to easily pick out the entries that match a certain criteria unlike with SQL where it can be a bit more complicated.

Choosing between T-SQL and SQL is all up to the user. Still, using T-SQL is still better when you are dealing with Microsoft SQL Server installations. This is because T-SQL is also from Microsoft, and using the two together maximizes compatibility. SQL is preferred by people who have multiple backends.

You can add this to your _Layout.cshtml:

@using MyProj.ViewModels;
...
    @if (TempData["UserMessage"] != null)
    {
        var message = (MessageViewModel)TempData["UserMessage"];
        <div class="alert @message.CssClassName" role="alert">
            <button type="button" class="close" data-dismiss="alert" aria-label="Close">
                <span aria-hidden="true">&times;</span>
            </button>
            <strong>@message.Title</strong>
            @message.Message
        </div>
    }

Then if you want to throw an error message in your controller:

    TempData["UserMessage"] = new MessageViewModel() { CssClassName = "alert-danger  alert-dismissible", Title = "Error", Message = "This is an error message" };

MessageViewModel.cs:

public class MessageViewModel
    {
        public string CssClassName { get; set; }
        public string Title { get; set; }
        public string Message { get; set; }
    }

Note: Using Bootstrap 4 classes.

If you give generally give a span the property display:block, it'll then behave like a div, i.e you can set width and height.

You can also skip the div or span and just set the a the to display: block and apply the backgound style to it.

<a href="" class="myImage"><!----></a>


    <style>
      .myImage {display: block; width: 160px; height: 20px; margin:0 0 10px 0; background: url(image.png) center top no-repeat;}
.myImage:hover{background-image(image_hover.png);}
    </style>

Serial sends data 8 bits at a time, that translates to 1 byte and 1 byte means 1 character.

You need to implement your own method that can read characters into a buffer until some sentinel is reached. The convention is to send a message like 12431\n indicating one line.

So what you need to do is to implement a buffer that will store X number of characters and as soon as you reach that \n, perform your operation on the line and proceed to read the next line into the buffer.

Note you will have to take care of buffer overflow cases i.e. when a line is received that is longer than your buffer etc...

EDIT

import serial

ser = serial.Serial(
    port='COM5',\
    baudrate=9600,\
    parity=serial.PARITY_NONE,\
    stopbits=serial.STOPBITS_ONE,\
    bytesize=serial.EIGHTBITS,\
        timeout=0)

print("connected to: " + ser.portstr)

#this will store the line
line = []

while True:
    for c in ser.read():
        line.append(c)
        if c == '\n':
            print("Line: " + ''.join(line))
            line = []
            break

ser.close()

These will also redirect both:

yourcommand  &> /dev/null

yourcommand  >& /dev/null

though the bash manual says the first is preferred.

FragmentActivity gives you all of the functionality of Activity plus the ability to use Fragments which are very useful in many cases, particularly when working with the ActionBar, which is the best way to use Tabs in Android.

If you are only targeting Honeycomb (v11) or greater devices, then you can use Activity and use the native Fragments introduced in v11 without issue. FragmentActivity was built specifically as part of the Support Library to back port some of those useful features (such as Fragments) back to older devices.

I should also note that you'll probably find the Backward Compatibility - Implementing Tabs training very helpful going forward.

The ng-model attribute sets the selected option and also allows you to pipe a filter like orderBy:orderModel.value

index.html

<select ng-model="orderModel" ng-options="option.name for option in orderOptions"></select>

controllers.js

$scope.orderOptions = [
    {"name":"Newest","value":"age"},
    {"name":"Alphabetical","value":"name"}
];

$scope.orderModel = $scope.orderOptions[0];

You can't, you'll have to do something like

<script type="text/javascript">
   var php_var = "<?php echo $php_var; ?>";
</script>

You can also load it with AJAX

rhino is right, the snippet lacks of a type for the sake of brevity.

Also, note that if $php_var has quotes, it will break your script. You shall use addslashes, htmlentities or a custom function.

Using only "native" Windows utilities, try the following, where "516" is the process ID that you want the image name for:

for /f "delims=," %a in ( 'tasklist /fi "PID eq 516" /nh /fo:csv' ) do ( echo %~a )
for /f %a in ( 'tasklist /fi "PID eq 516" ^| findstr "516"' ) do ( echo %a )

Or you could use wmic (the Windows Management Instrumentation Command-line tool) and get the full path to the executable:

wmic process where processId=516 get name
wmic process where processId=516 get ExecutablePath

Or you could download Microsoft PsTools, or specifically download just the pslist utility, and use PsList:

for /f %a in ( 'pslist 516 ^| findstr "516"' ) do ( echo %a )

It's working for me:

<%= image_tag( root_url + "images/rss.jpg", size: "50x50", :alt => "rss feed") -%>

The equivalent in a more modern and browser compatible way, using modern addEventListener APIs.

window.addEventListener('beforeunload', (event) => {
  // Cancel the event as stated by the standard.
  event.preventDefault();
  // Chrome requires returnValue to be set.
  event.returnValue = '';
});

Source: https://developer.mozilla.org/en-US/docs/Web/Events/beforeunload

You can give a try to Apache Commons Collections.

There is a class CollectionUtils that allows you to select or filter items by custom Predicate.

Your code would be like this:

Predicate condition = new Predicate() {
   boolean evaluate(Object sample) {
        return ((Sample)sample).value3.equals("three");
   }
};
List result = CollectionUtils.select( list, condition );

Update:

In java8, using Lambdas and StreamAPI this should be:

List<Sample> result = list.stream()
     .filter(item -> item.value3.equals("three"))
     .collect(Collectors.toList());

much nicer!

Nowadays you can do...

switch ([$group1, $group2]){
    case ["users", "location"]:
    case ["users", "online"]:
        Ju_le_do_the_thing();
        break;
    case ["forum", $group2]:
        Foo_the_bar();
        break;
}

this Func may help you . it add every list object to grid view

private void show_data()
        {
            BindingSource Source = new BindingSource();

            for (int i = 0; i < CC.Contects.Count; i++)
            {
                Source.Add(CC.Contects.ElementAt(i));
            };


            Data_View.DataSource = Source;

        }

Answered the same question here:

• https://stackoverflow.com/a/23298715/1007358

To repost:

After searching through many solutions I decided to blog about how to sort in jquery. In summary, steps to sort jquery "array-like" objects by data attribute...

1. select all object via jquery selector
2. convert to actual array (not array-like jquery object)
3. sort the array of objects
4. convert back to jquery object with the array of dom objects

Html

<div class="item" data-order="2">2</div>
<div class="item" data-order="1">1</div>
<div class="item" data-order="4">4</div>
<div class="item" data-order="3">3</div>

Plain jquery selector

$('.item');

[<div class="item" data-order="2">2</div>,
 <div class="item" data-order="1">1</div>,
 <div class="item" data-order="4">4</div>,
 <div class="item" data-order="3">3</div>
]

Lets sort this by data-order

function getSorted(selector, attrName) {
    return $($(selector).toArray().sort(function(a, b){
        var aVal = parseInt(a.getAttribute(attrName)),
            bVal = parseInt(b.getAttribute(attrName));
        return aVal - bVal;
    }));
}

> getSorted('.item', 'data-order')

[<div class="item" data-order="1">1</div>,
 <div class="item" data-order="2">2</div>,
 <div class="item" data-order="3">3</div>,
 <div class="item" data-order="4">4</div>
]

See how getSorted() works.

Hope this helps!

Simple, without any other API:

To add 8 days:

Date today=new Date();
long ltime=today.getTime()+8*24*60*60*1000;
Date today8=new Date(ltime);

A simple solution is to wrap the query into a subselect with the ORDER statement first and applying the GROUP BY later:

SELECT * FROM ( 
    SELECT `timestamp`, `fromEmail`, `subject`
    FROM `incomingEmails` 
    ORDER BY `timestamp` DESC
) AS tmp_table GROUP BY LOWER(`fromEmail`)

This is similar to using the join but looks much nicer.

Using non-aggregate columns in a SELECT with a GROUP BY clause is non-standard. MySQL will generally return the values of the first row it finds and discard the rest. Any ORDER BY clauses will only apply to the returned column value, not to the discarded ones.

IMPORTANT UPDATE Selecting non-aggregate columns used to work in practice but should not be relied upon. Per the MySQL documentation "this is useful primarily when all values in each nonaggregated column not named in the GROUP BY are the same for each group. The server is free to choose any value from each group, so unless they are the same, the values chosen are indeterminate."

As of 5.7.5 ONLY_FULL_GROUP_BY is enabled by default so non-aggregate columns cause query errors (ER_WRONG_FIELD_WITH_GROUP)

As @mikep points out below the solution is to use ANY_VALUE() from 5.7 and above

See http://www.cafewebmaster.com/mysql-order-sort-group https://dev.mysql.com/doc/refman/5.6/en/group-by-handling.html https://dev.mysql.com/doc/refman/5.7/en/group-by-handling.html https://dev.mysql.com/doc/refman/5.7/en/miscellaneous-functions.html#function_any-value

A solution for me:

$old_ErrorActionPreference = $ErrorActionPreference
$ErrorActionPreference = 'SilentlyContinue'
if((Get-PSSessionConfiguration -Name "MyShellUri" -ErrorAction SilentlyContinue) -eq $null) {
   WriteTraceForTrans "The session configuration MyShellUri is already unregistered."
}
else {        
   #Unregister-PSSessionConfiguration -Name "MyShellUri" -Force -ErrorAction Ignore
}
$ErrorActionPreference = $old_ErrorActionPreference 

Or use try-catch

try { 

(Get-PSSessionConfiguration -Name "MyShellUri" -ErrorAction SilentlyContinue)

} 
catch {

}

The simplest way is using HTML META tag like this:

<meta http-equiv="refresh" content="3;url=http://example.com/" />

Wikipedia

("Jesse" or "jesse")

The above expression tests whether or not "Jesse" evaluates to True. If it does, then the expression will return it; otherwise, it will return "jesse". The expression is equivalent to writing:

"Jesse" if "Jesse" else "jesse"

Because "Jesse" is a non-empty string though, it will always evaluate to True and thus be returned:

>>> bool("Jesse")  # Non-empty strings evaluate to True in Python
True
>>> bool("")  # Empty strings evaluate to False
False
>>>
>>> ("Jesse" or "jesse")
'Jesse'
>>> ("" or "jesse")
'jesse'
>>>

This means that the expression:

name == ("Jesse" or "jesse")

is basically equivalent to writing this:

name == "Jesse"

In order to fix your problem, you can use the in operator:

# Test whether the value of name can be found in the tuple ("Jesse", "jesse")
if name in ("Jesse", "jesse"):

Or, you can lowercase the value of name with str.lower and then compare it to "jesse" directly:

# This will also handle inputs such as "JeSSe", "jESSE", "JESSE", etc.
if name.lower() == "jesse":

                DispatchQueue.main.asyncAfter(deadline: .now() + delay, execute: {
                    completion()
                })
            }
        }
    }

}

Usage

DispatchQueue.background(delay: 3.0, background: {
    // do something in background
}, completion: {
    // when background job finishes, wait 3 seconds and do something in main thread
})

DispatchQueue.background(background: {
    // do something in background
}, completion:{
    // when background job finished, do something in main thread
})

DispatchQueue.background(delay: 3.0, completion:{
    // do something in main thread after 3 seconds
})

Simply add this

$id = ''; 
if( isset( $_GET['id'])) {
    $id = $_GET['id']; 
} 

JVM head dump is a snapshot of a JVM heap memory in a given time. So its simply a heap representation of JVM. That is the state of the objects.

JVM thread dump is a snapshot of a JVM threads at a given time. So thats what were threads doing at any given time. This is the state of threads. This helps understanding such as locked threads, hanged threads and running threads.

Head dump has more information of java class level information than a thread dump. For example Head dump is good to analyse JVM heap memory issues and OutOfMemoryError errors. JVM head dump is generated automatically when there is something like OutOfMemoryError has taken place. Heap dump can be created manually by killing the process using kill -3 . Generating a heap dump is a intensive computing task, which will probably hang your jvm. so itsn't a methond to use offetenly. Heap can be analysed using tools such as eclipse memory analyser.

Core dump is a os level memory usage of objects. It has more informaiton than a head dump. core dump is not created when we kill a process purposely.

In direct response to the Question Title...

dplyr definitely does things that data.table can not.

Your point #3

dplyr abstracts (or will) potential DB interactions

is a direct answer to your own question but isn't elevated to a high enough level. dplyr is truly an extendable front-end to multiple data storage mechanisms where as data.table is an extension to a single one.

Look at dplyr as a back-end agnostic interface, with all of the targets using the same grammer, where you can extend the targets and handlers at will. data.table is, from the dplyr perspective, one of those targets.

You will never (I hope) see a day that data.table attempts to translate your queries to create SQL statements that operate with on-disk or networked data stores.

dplyr can possibly do things data.table will not or might not do as well.

Based on the design of working in-memory, data.table could have a much more difficult time extending itself into parallel processing of queries than dplyr.

In response to the in-body questions...

Usage

Are there analytical tasks that are a lot easier to code with one or the other package for people familiar with the packages (i.e. some combination of keystrokes required vs. required level of esotericism, where less of each is a good thing).

This may seem like a punt but the real answer is no. People familiar with tools seem to use the either the one most familiar to them or the one that is actually the right one for the job at hand. With that being said, sometimes you want to present a particular readability, sometimes a level of performance, and when you have need for a high enough level of both you may just need another tool to go along with what you already have to make clearer abstractions.

Performance

Are there analytical tasks that are performed substantially (i.e. more than 2x) more efficiently in one package vs. another.

Again, no. data.table excels at being efficient in everything it does where dplyr gets the burden of being limited in some respects to the underlying data store and registered handlers.

This means when you run into a performance issue with data.table you can be pretty sure it is in your query function and if it is actually a bottleneck with data.table then you've won yourself the joy of filing a report. This is also true when dplyr is using data.table as the back-end; you may see some overhead from dplyr but odds are it is your query.

When dplyr has performance issues with back-ends you can get around them by registering a function for hybrid evaluation or (in the case of databases) manipulating the generated query prior to execution.

Also see the accepted answer to when is plyr better than data.table?

If your input was structured as XML, you could use the importXML function. (More info here at quirksmode).

If it isn't XML, and there isn't an equivalent function for importing plain text, then you could open it in a hidden iframe and then read the contents from there.

The best practice is selecting the most appropriate one.

.Net Framework 4.0 Beta 2 has a new IsNullOrWhiteSpace() method for strings which generalizes the IsNullOrEmpty() method to also include other white space besides empty string.

The term “white space” includes all characters that are not visible on screen. For example, space, line break, tab and empty string are white space characters*.

Reference : Here

For performance, IsNullOrWhiteSpace is not ideal but is good. The method calls will result in a small performance penalty. Further, the IsWhiteSpace method itself has some indirections that can be removed if you are not using Unicode data. As always, premature optimization may be evil, but it is also fun.

Reference : Here

Check the source code (Reference Source .NET Framework 4.6.2)

IsNullorEmpty

[Pure]
public static bool IsNullOrEmpty(String value) {
    return (value == null || value.Length == 0);
}

IsNullOrWhiteSpace

[Pure]
public static bool IsNullOrWhiteSpace(String value) {
    if (value == null) return true;

    for(int i = 0; i < value.Length; i++) {
        if(!Char.IsWhiteSpace(value[i])) return false;
    }

    return true;
}

Examples

string nullString = null;
string emptyString = "";
string whitespaceString = "    ";
string nonEmptyString = "abc123";

bool result;

result = String.IsNullOrEmpty(nullString);            // true
result = String.IsNullOrEmpty(emptyString);           // true
result = String.IsNullOrEmpty(whitespaceString);      // false
result = String.IsNullOrEmpty(nonEmptyString);        // false

result = String.IsNullOrWhiteSpace(nullString);       // true
result = String.IsNullOrWhiteSpace(emptyString);      // true
result = String.IsNullOrWhiteSpace(whitespaceString); // true
result = String.IsNullOrWhiteSpace(nonEmptyString);   // false

Here's another:

data[data$Code == "A" | data$Code == "B", ]

It's also worth mentioning that the subsetting factor doesn't have to be part of the data frame if it matches the data frame rows in length and order. In this case we made our data frame from this factor anyway. So,

data[Code == "A" | Code == "B", ]

also works, which is one of the really useful things about R.

string domainName = Request.Url.Host

You might want to use helper library like http://momentjs.com/ which wraps the native javascript date object for easier manipulations

Then you can do things like:

var day = moment("12-25-1995", "MM-DD-YYYY");

or

var day = moment("25/12/1995", "DD/MM/YYYY");

then operate on the date

day.add('days', 7)

and to get the native javascript date

day.toDate();

Above code might not be working due to possibility if your view controller belongs to a navigation controller. If yes then it has to obey the rules of the navigation controller even if it has different orientation rules itself. A better approach would be to let the view controller decide for itself and the navigation controller will use the decision of the top most view controller.

We can support both locking to current orientation and autorotating to lock on a specific orientation with this generic extension on UINavigationController: -:

extension UINavigationController {
            public override func shouldAutorotate() -> Bool {
                return visibleViewController.shouldAutorotate()
            }

        public override func supportedInterfaceOrientations() -> UIInterfaceOrientationMask {
            return (visibleViewController?.supportedInterfaceOrientations())!
        }
    }

Now inside your view controller we can

class ViewController: UIViewController {
    // MARK: Autoroate configuration

    override func shouldAutorotate() -> Bool {
        if (UIDevice.currentDevice().orientation == UIDeviceOrientation.Portrait ||
            UIDevice.currentDevice().orientation == UIDeviceOrientation.PortraitUpsideDown ||
            UIDevice.currentDevice().orientation == UIDeviceOrientation.Unknown) {
                return true
        }
        else {
            return false
        }
    }

    override func supportedInterfaceOrientations() -> Int {
        return Int(UIInterfaceOrientationMask.Portrait.rawValue) | Int(UIInterfaceOrientationMask.PortraitUpsideDown.rawValue)
    }
}

Hope it helps. Thanks

Looking at the Eclipse plugin docs I found some useful tasks that rebuilt my classpath and updated the required dependencies.

• First try gradle cleanEclipse to clean the Eclipse configuration completely. If this doesn;t work you may try more specific tasks:
  • gradle cleanEclipseProject to remove the .project file
  • gradle cleanEclipseClasspath to empty the project's classpath
• Finally gradle eclipse to rebuild the Eclipse configuration

As I noticed your description, you just know that your parser will give you a dictionary that its values are dictionary too like this:

sampleDict = {
              "key1": {"key10": "value10", "key11": "value11"},
              "key2": {"key20": "value20", "key21": "value21"}
              }

So you have to iterate over your parent dictionary. If you want to print out or access all first dictionary keys in sampleDict.values() list, you may use something like this:

for key, value in sampleDict.items():
    print value.keys()[0]

If you want to just access first key of the first item in sampleDict.values(), this may be useful:

print sampleDict.values()[0].keys()[0]

If you use the example you gave in the question, I mean:

sampleDict = {
              'Apple': {'American':'16', 'Mexican':10, 'Chinese':5},
              'Grapes':{'Arabian':'25','Indian':'20'}
              }

The output for the first code is:

American
Indian

And the output for the second code is:

American

EDIT 1:

Above code examples does not work for version 3 and above of python; since from version 3, python changed the type of output of methods keys and values from list to dict_values. Type dict_values is not accepting indexing, but it is iterable. So you need to change above codes as below:

First One:

for key, value in sampleDict.items():
    print(list(value.keys())[0])

Second One:

print(list(list(sampleDict.values())[0].keys())[0])

As noted at Detecting the onload event of a window opened with window.open, the following solution is ideal:

/* Internet Explorer will throw an error on one of the two statements, Firefox on the other one of the two. */
(function(ow) {
    ow.addEventListener("load", function() { alert("loaded"); }, false);
    ow.attachEvent("onload", function() { alert("loaded"); }, false);
})(window.open(prompt("Where are you going today?", location.href), "snapDown"));

Other comments and answers perpetrate several erroneous misconceptions as explained below.

The following script demonstrates the fickleness of defining onload. Apply the script to a "fast loading" location for the window being opened, such as one with the file: scheme and compare this to a "slow" location to see the problem: it is possible to see either onload message or none at all (by reloading a loaded page all 3 variations can be seen). It is also assumed that the page being loaded itself does not define an onload event which would compound the problem.

The onload definitions are evidently not "inside pop-up document markup":

var popup = window.open(location.href, "snapDown");
popup.onload = function() { alert("message one"); };
alert("message 1 maybe too soon\n" + popup.onload);
popup.onload = function() { alert("message two"); };
alert("message 2 maybe too late\n" + popup.onload);

What you can do:

• open a window with a "foreign" URL
• on that window's address bar enter a javascript: URI -- the code will run with the same privileges as the domain of the "foreign" URL
  The javascript: URI may need to be bookmarked if typing it in the address bar has no effect (may be the case with some browsers released around 2012)

Thus any page, well almost, irregardless of origin, can be modified like:

if(confirm("wipe out links & anchors?\n" + document.body.innerHTML))
    void(document.body.innerHTML=document.body.innerHTML.replace(/<a /g,"< a "))

Well, almost:

jar:file:///usr/lib/firefox/omni.ja!/chrome/toolkit/content/global/aboutSupport.xhtml, Mozilla Firefox's troubleshooting page and other Jar archives are exceptions.

As another example, to routinely disable Google's usurping of target hits, change its rwt function with the following URI:

javascript: void(rwt = function(unusurpURL) { return unusurpURL; })

(Optionally Bookmark the above as e.g. "Spay Google" ("neutralize Google"?)

This bookmark is then clicked before any Google hits are clicked, so bookmarks of any of those hits are clean and not the mongrelized perverted aberrations that Google made of them.

It should be noted that addEventListener in Firefox only has a non-standard fourth, boolean parameter, which if true allows untrusted content triggers to be instantiated for foreign pages.

Ask yourself: will the installed package be required for use of my module, or will it only be required for developing it?

You should be able to use join, which joins on the index as default. Given your desired result, you must use outer as the join type.

I believe prestomanifesto was on the right track. It depends on what kind of element it is. You would need to use element.get_attribute('value') for input elements and element.text to return the text node of an element.

You could check the WebElement object with element.tag_name to find out what kind of element it is and return the appropriate value.

This should help you figure out:

driver = webdriver.Firefox()
driver.get('http://www.w3c.org')
element = driver.find_element_by_name('q')
element.send_keys('hi mom')

element_text = element.text
element_attribute_value = element.get_attribute('value')

print element
print 'element.text: {0}'.format(element_text)
print 'element.get_attribute(\'value\'): {0}'.format(element_attribute_value)
driver.quit()

To get the result with two decimals, you can do like this :

var discount = Math.round((100 - (price / listprice) * 100) * 100) / 100;

The value to be rounded is multiplied by 100 to keep the first two digits, then we divide by 100 to get the actual result.

You need to put the text-align:center on the containing div, not on the input itself.

What about?

df.columns.values[2] = "new_name"

The least complicated, most straight-forward way of doing this is by simply wrapping your main query with the pivot in a common table expression, then grouping/aggregating.

WITH PivotCTE AS
(
    select * from  mytransactions
    pivot (sum (totalcount) for country in ([Australia], [Austria])) as pvt
)
SELECT
    numericmonth,
    chardate,
    SUM(totalamount) AS totalamount,
    SUM(ISNULL(Australia, 0)) AS Australia,
    SUM(ISNULL(Austria, 0)) Austria
FROM PivotCTE
GROUP BY numericmonth, chardate

The ISNULL is to stop a NULL value from nullifying the sum (because NULL + any value = NULL)

Browsers are getting smarter. Today your browser (depending on the version) might skip the image loading if it can determine it's not useful.

The image has a display:none style but its size may be read by the script. Chrome v68.0 does not load images if the parent is hidden.

You may check it there : http://jsfiddle.net/tnk3j08s/

You could also have checked it by looking at the "network" tab of your browser's developer tools.

Note that if the browser is on a small CPU computer, not having to render the image (and layout the page) will make the whole rendering operation faster but I doubt this is something that really makes sense today.

If you want to prevent the image from loading you may simply not add the IMG element to your document (or set the IMG src attribute to "data:" or "about:blank").

If you want to know if "1" ou 1 can be casted to a number, you can use this code :

if (isNaN(i*1)) {
     console.log('i is not a number'); 
}

This worked for me:

def smallest_missing_positive_integer(A):
A.sort()
N = len(A)

now = A[0]
for i in range(1, N, 1):
  next = A[i]
  
  #check if there is no gap between 2 numbers and if positive
  # "now + 1" is the "gap"
  if (next > now + 1):
    if now + 1 > 0:
      return now + 1 #return the gap
  now = next
    
return max(1, A[N-1] + 1) #if there is no positive number returns 1, otherwise the end of A+1

If the commit you want to revert is a merged commit (has been merged already), then you should either -m 1 or -m 2 option as shown below. This will let git know which parent commit of the merged commit to use. More details can be found HERE.

TAP-Win32 should not be installed on the 64bit version. Download the right one and try again!

this is just as a side note, but generally what you want to do is keep size on the Session and ViewState small. I generally just store IDs and small amounts of packets in Session and ViewState.

for instance if you want to pass large chunks of data from one page to another, you can store an ID in the querystring and use that ID to either get data from a database or a file.

PS: but like I said, this might be totally unrelated to your query :)

This will work although when embedding PHP in HTML it is better practice to use the following form:

    </tr>
    <?php endforeach; ?>
</table>

I was getting this on an asp.net 2.0 iis7 Windows2008 site. Same code on iis6 worked fine. It was causing an issue for me because it was messing up the login process. User would login and get a 302 to default.asxp, which would get through page_load, but not as far as pre-render before iis7 would send a 302 back to login.aspx without the auth cookie. I started playing with app pool settings, and for some reason 'enable 32 bit applications' seems to have fixed it. No idea why, since this site isn't doing anything special that should require any 32 bit drivers. We have some sites that still use Access that require 32bit, but not our straight SQL sites like this one.

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.

The simplest way is using libraries like google-http-java-client but if you want parse the JSON response by yourself you can do that in a multiple ways, you can use org.json, json-simple, Gson, minimal-json, jackson-mapper-asl (from 1.x)... etc

A set of simple examples:

Using Gson:

import java.io.IOException;

import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.util.EntityUtils;

public class Gson {

    public static void main(String[] args) {
    }

    public HttpResponse http(String url, String body) {

        try (CloseableHttpClient httpClient = HttpClientBuilder.create().build()) {
            HttpPost request = new HttpPost(url);
            StringEntity params = new StringEntity(body);
            request.addHeader("content-type", "application/json");
            request.setEntity(params);
            HttpResponse result = httpClient.execute(request);
            String json = EntityUtils.toString(result.getEntity(), "UTF-8");

            com.google.gson.Gson gson = new com.google.gson.Gson();
            Response respuesta = gson.fromJson(json, Response.class);

            System.out.println(respuesta.getExample());
            System.out.println(respuesta.getFr());

        } catch (IOException ex) {
        }
        return null;
    }

    public class Response{

        private String example;
        private String fr;

you might want to look at the online version of xsv

In Android Studio, go to app --> src --> main --> res-->

File --> new --> Activity --> ActivityType [choose a acticity that you want]

Fill in the details of the New Android Activity and click Finish.

NSNumber *value = [NSNumber numberWithInt:UIInterfaceOrientationLandscapeLeft]; [[UIDevice currentDevice] setValue:value forKey:@"orientation"];

does work but you have to return shouldAutorotate with YES in your view controller

- (BOOL)shouldAutorotate
{
    return self.shouldAutoRotate;
}

But if you do that, your VC will autorotate if the user rotates the device... so I changed it to:

@property (nonatomic, assign) BOOL shouldAutoRotate;

- (BOOL)shouldAutorotate
{
    return self.shouldAutoRotate;
}

and I call

- (void)swithInterfaceOrientation:(UIInterfaceOrientation)orientation
{
    self.rootVC.shouldAutoRotate = YES;

    NSNumber *value = [NSNumber numberWithInt: orientation];
    [[UIDevice currentDevice] setValue:value forKey:@"orientation"];
}

to force a new orientation with a button-click. To set back shouldAutoRotate to NO, I added to my rootVC

- (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation
{
    self.shouldAutoRotate = NO;
}

PS: This workaround does work in all simulators too.

Edit: Passing the operator as a reference doesnt work. For simplicity, understand it as a function pointer. You just send the pointer, not a reference. I think you are trying to write something like this.

struct Square
{
    double operator()(double number) { return number * number; }
};

template <class Function>
double integrate(Function f, double a, double b, unsigned int intervals)
{
    double delta = (b - a) / intervals, sum = 0.0;

    while(a < b)
    {
        sum += f(a) * delta;
        a += delta;
    }

    return sum;
}

. .

std::cout << "interval : " << i << tab << tab << "intgeration = "
 << integrate(Square(), 0.0, 1.0, 10) << std::endl;

heroku ps:restart [web|worker] --app app_name

works for all processes declared in your Procfile. So if you have multiple web processes or worker processes, each labeled with a number, you can selectively restart one of them:

heroku ps:restart web.2 --app app_name
heroku ps:restart worker.3 --app app_name

#include <experimental/filesystem> // or #include <filesystem> for C++17 and up
    
namespace fs = std::experimental::filesystem;


if (!fs::is_directory("src") || !fs::exists("src")) { // Check if src folder exists
    fs::create_directory("src"); // create src folder
}

Here is a full example on how to transform your date in different types:

Date date = Calendar.getInstance().getTime();

    // Display a date in day, month, year format
    DateFormat formatter = new SimpleDateFormat("dd/MM/yyyy");
    String today = formatter.format(date);
    System.out.println("Today : " + today);

    // Display date with day name in a short format
    formatter = new SimpleDateFormat("EEE, dd/MM/yyyy");
    today = formatter.format(date);
    System.out.println("Today : " + today);

    // Display date with a short day and month name
    formatter = new SimpleDateFormat("EEE, dd MMM yyyy");
    today = formatter.format(date);
    System.out.println("Today : " + today);

    // Formatting date with full day and month name and show time up to
    // milliseconds with AM/PM
    formatter = new SimpleDateFormat("EEEE, dd MMMM yyyy, hh:mm:ss.SSS a");
    today = formatter.format(date);
    System.out.println("Today : " + today);

fsevents is dealt differently in mac and other linux system. Linux system ignores fsevents whereas mac install it. As the above error message states that fsevents is optional and it is skipped in installation process.

You can run npm install --no-optional command in linux system to avoid above warning.

To remove spaces from left/right, use LTRIM/RTRIM. What you had

UPDATE *tablename*
   SET *columnname* = LTRIM(RTRIM(*columnname*));

would have worked on ALL the rows. To minimize updates if you don't need to update, the update code is unchanged, but the LIKE expression in the WHERE clause would have been

UPDATE [tablename]
   SET [columnname] = LTRIM(RTRIM([columnname]))
 WHERE 32 in (ASCII([columname]), ASCII(REVERSE([columname])));

Note: 32 is the ascii code for the space character.

Save the archiveName image to a tar file. I will use the /media/sf_docker_vm/ to save the image.

stratos@Dev-PC:~$ docker save imageID > /media/sf_docker_vm/archiveName.tar

Copy the archiveName.tar file to your new Docker instance using whatever method works in your environment, for example FTP, SCP, etc.

Run the docker load command on your new Docker instance and specify the location of the image tar file.

stratos@Dev-PC:~$ docker load < /media/sf_docker_vm/archiveName.tar

Finally, run the docker images command to check that the image is now available.

stratos@Dev-PC:~$ docker images

Please find this detailed post.

This answer seems relevant since the OP makes reference to a need for a multi-OS solution. This Github help article details available approaches for handling lines endings cross-OS. There are global and per-repo approaches to managing cross-os line endings.

Global approach

Configure Git line endings handling on Linux or OS X:

git config --global core.autocrlf input

Configure Git line endings handling on Windows:

git config --global core.autocrlf true

Per-repo approach:

In the root of your repo, create a .gitattributes file and define line ending settings for your project files, one line at a time in the following format: path_regex line-ending-settings where line-ending-settings is one of the following:

• text
• binary (files that Git should not modify line endings for - as this can cause some image types such as PNGs not to render in a browser)

The text value can be configured further to instruct Git on how to handle line endings for matching files:

• text - Changes line endings to OS native line endings.
• text eol=crlf - Converts line endings to CRLF on checkout.
• text eol=lf - Converts line endings to LF on checkout.
• text=auto - Sensible default that leaves line handle up to Git's discretion.

Here is the content of a sample .gitattributes file:

# Set the default behavior for all files.
* text=auto

# Normalized and converts to 
# native line endings on checkout.
*.c text
*.h text

# Convert to CRLF line endings on checkout.
*.sln text eol=crlf

# Convert to LF line endings on checkout.
*.sh text eol=lf

# Binary files.
*.png binary
*.jpg binary

More on how to refresh your repo after changing line endings settings here. Tldr:

backup your files with Git, delete every file in your repository (except the .git directory), and then restore the files all at once. Save your current files in Git, so that none of your work is lost.

git add . -u

git commit -m "Saving files before refreshing line endings"

Remove the index and force Git to rescan the working directory.

rm .git/index

Rewrite the Git index to pick up all the new line endings.

git reset

Show the rewritten, normalized files.

In some cases, this is all that needs to be done. Others may need to complete the following additional steps:

git status

Add all your changed files back, and prepare them for a commit. This is your chance to inspect which files, if any, were unchanged.

git add -u

It is perfectly safe to see a lot of messages here that read[s] "warning: CRLF will be replaced by LF in file."

Rewrite the .gitattributes file.

git add .gitattributes

Commit the changes to your repository.

git commit -m "Normalize all the line endings"

Assuming regular PCRE-style regex flavors:

If you want to check for it as a single, full word, it's \bTest\b, with appropriate flags for case insensitivity if desired and delimiters for your programming language. \b represents a "word boundary", that is, a point between characters where a word can be considered to start or end. For example, since spaces are used to separate words, there will be a word boundary on either side of a space.

If you want to check for it as part of the word, it's just Test, again with appropriate flags for case insensitivity. Note that usually, dedicated "substring" methods tend to be faster in this case, because it removes the overhead of parsing the regex.

SELECT name
FROM sys.objects
WHERE type = 'P'
AND (DATEDIFF(D,modify_date, GETDATE()) < 7
     OR DATEDIFF(D,create_date, GETDATE()) < 7)

Why can't we create Object of Abstract Class ? When we create a pure virtual function in Abstract class, we reserve a slot for a function in the VTABLE(studied in last topic), but doesn't put any address in that slot. Hence the VTABLE will be incomplete. As the VTABLE for Abstract class is incomplete, hence the compiler will not let the creation of object for such class and will display an errror message whenever you try to do so.

Pure Virtual definitions

Pure Virtual functions can be given a small definition in the Abstract class, which you want all the derived classes to have. Still you cannot create object of Abstract class. Also, the Pure Virtual function must be defined outside the class definition. If you will define it inside the class definition, complier will give an error. Inline pure virtual definition is Illegal.

For the sake of completeness, here is the ‘one-liner’ corresponding to @prunge’s excellent answer:

User user1 = users.stream()
        .filter(user -> user.getId() == 1)
        .reduce((a, b) -> {
            throw new IllegalStateException("Multiple elements: " + a + ", " + b);
        })
        .get();

This obtains the sole matching element from the stream, throwing

• NoSuchElementException in case the stream is empty, or
• IllegalStateException in case the stream contains more than one matching element.

A variation of this approach avoids throwing an exception early and instead represents the result as an Optional containing either the sole element, or nothing (empty) if there are zero or multiple elements:

Optional<User> user1 = users.stream()
        .filter(user -> user.getId() == 1)
        .collect(Collectors.reducing((a, b) -> null));

from google.colab import drive
drive.mount('/content/drive')

This worked perfect for me I was later able to use the os library to access my files just like how I access them on my PC

margin = space around (outside) the element from border outwards.

padding = space around (inside) the element from text to border.

John Gruber (who wrote Markdown, which is made of regular expressions and is used right here on Stack Overflow) had a go at producing a regular expression that recognises URLs in text:

http://daringfireball.net/2009/11/liberal_regex_for_matching_urls

If you just want to grab the URL (i.e. you’re not really trying to parse the HTML), this might be more lightweight than an HTML parser.

Here is an answer to your question that goes into detail: http://www.velocityreviews.com/forums/t372598-maximum-size-of-byte-array.html

You may want to mention which version of .NET you are using and your memory size.

You will be stuck to a 2G, for your application, limit though, so it depends on what is in your array.

This indicates the linux has delivered a SIGTERM to your process. This is usually at the request of some other process (via kill()) but could also be sent by your process to itself (using raise()). This signal requests an orderly shutdown of your process.

If you need a quick cheatsheet of signal numbers, open a bash shell and:

$ kill -l
 1) SIGHUP   2) SIGINT   3) SIGQUIT  4) SIGILL
 5) SIGTRAP  6) SIGABRT  7) SIGBUS   8) SIGFPE
 9) SIGKILL 10) SIGUSR1 11) SIGSEGV 12) SIGUSR2
13) SIGPIPE 14) SIGALRM 15) SIGTERM 16) SIGSTKFLT
17) SIGCHLD 18) SIGCONT 19) SIGSTOP 20) SIGTSTP
21) SIGTTIN 22) SIGTTOU 23) SIGURG  24) SIGXCPU
25) SIGXFSZ 26) SIGVTALRM   27) SIGPROF 28) SIGWINCH
29) SIGIO   30) SIGPWR  31) SIGSYS  34) SIGRTMIN
35) SIGRTMIN+1  36) SIGRTMIN+2  37) SIGRTMIN+3  38) SIGRTMIN+4
39) SIGRTMIN+5  40) SIGRTMIN+6  41) SIGRTMIN+7  42) SIGRTMIN+8
43) SIGRTMIN+9  44) SIGRTMIN+10 45) SIGRTMIN+11 46) SIGRTMIN+12
47) SIGRTMIN+13 48) SIGRTMIN+14 49) SIGRTMIN+15 50) SIGRTMAX-14
51) SIGRTMAX-13 52) SIGRTMAX-12 53) SIGRTMAX-11 54) SIGRTMAX-10
55) SIGRTMAX-9  56) SIGRTMAX-8  57) SIGRTMAX-7  58) SIGRTMAX-6
59) SIGRTMAX-5  60) SIGRTMAX-4  61) SIGRTMAX-3  62) SIGRTMAX-2
63) SIGRTMAX-1  64) SIGRTMAX    

You can determine the sender by using an appropriate signal handler like:

#include <signal.h>
#include <stdio.h>
#include <stdlib.h>

void sigterm_handler(int signal, siginfo_t *info, void *_unused)
{
  fprintf(stderr, "Received SIGTERM from process with pid = %u\n",
      info->si_pid);
  exit(0);
}

int main (void)
{
  struct sigaction action = {
    .sa_handler = NULL,
    .sa_sigaction = sigterm_handler,
    .sa_mask = 0,
    .sa_flags = SA_SIGINFO,
    .sa_restorer = NULL
  };

  sigaction(SIGTERM, &action, NULL);
  sleep(60);

  return 0;
}

Notice that the signal handler also includes a call to exit(). It's also possible for your program to continue to execute by ignoring the signal, but this isn't recommended in general (if it's a user doing it there's a good chance it will be followed by a SIGKILL if your process doesn't exit, and you lost your opportunity to do any cleanup then).

Use array_combine() to fuse the arrays together and iterate over the result.

$countries = array_combine($codes, $names);

Just to phrase things differently from the great answers above, as that has helped me get an intuitive understanding of negative margins:

A negative margin on an element allows it to eat up the space of its parent container.

Adding a (positive) margin on the bottom doesn't allow the element to do that - it only pushes back whatever element is below.

Highlighting the difference between two DataFrames

It is possible to use the DataFrame style property to highlight the background color of the cells where there is a difference.

Using the example data from the original question

The first step is to concatenate the DataFrames horizontally with the concat function and distinguish each frame with the keys parameter:

df_all = pd.concat([df.set_index('id'), df2.set_index('id')], 
                   axis='columns', keys=['First', 'Second'])
df_all

It's probably easier to swap the column levels and put the same column names next to each other:

df_final = df_all.swaplevel(axis='columns')[df.columns[1:]]
df_final

Now, its much easier to spot the differences in the frames. But, we can go further and use the style property to highlight the cells that are different. We define a custom function to do this which you can see in this part of the documentation.

def highlight_diff(data, color='yellow'):
    attr = 'background-color: {}'.format(color)
    other = data.xs('First', axis='columns', level=-1)
    return pd.DataFrame(np.where(data.ne(other, level=0), attr, ''),
                        index=data.index, columns=data.columns)

df_final.style.apply(highlight_diff, axis=None)

This will highlight cells that both have missing values. You can either fill them or provide extra logic so that they don't get highlighted.

You need to change from queue import Queue to from multiprocessing import Queue.

The root reason is the former Queue is designed for threading module Queue while the latter is for multiprocessing.Process module.

For details, you can read some source code or contact me!

UPDATE TABLE_NAME SET COLUMN_A = COLUMN_B;

Much easier. At least on Oracle SQL, i don't know if this works on other dialects as well.

I have this issue today with mat-option-group. The thing which solved me the problem is using in other provided event of mat-select : valueChange

I put here a little code for understanding :

<mat-form-field >
  <mat-label>Filter By</mat-label>
  <mat-select  panelClass="" #choosedValue (valueChange)="doSomething1(choosedValue.value)"> <!-- (valueChange)="doSomething1(choosedValue.value)" instead of (change) or other event-->

    <mat-option >-- None --</mat-option>
      <mat-optgroup  *ngFor="let group of filterData" [label]="group.viewValue"
                    style = "background-color: #0c5460">
        <mat-option *ngFor="let option of group.options" [value]="option.value">
          {{option.viewValue}}
        </mat-option>
      </mat-optgroup>
  </mat-select>
</mat-form-field>

You can use the tee command to redirect output:

/usr/bin/mysqldump -u user -pupasswd my-database | \
tee >(gzip -9 -c > /home/user/backup/mydatabase-backup-`date +\%m\%d_\%Y`.sql.gz)  | \
gzip> /home/user/backup2/mydatabase-backup-`date +\%m\%d_\%Y`.sql.gz 2>&1

see documentation here

you can use ls -sh in linux you can do sort also you need to go to dir where you want to check the size of files

Step 1: Add the submodule

   git submodule add git://some_repository.git some_repository

Step 2: Fix the submodule to a particular commit

By default the new submodule will be tracking HEAD of the master branch, but it will NOT be updated as you update your primary repository. In order to change the submodule to track a particular commit or different branch, change directory to the submodule folder and switch branches just like you would in a normal repository.

   git checkout -b some_branch origin/some_branch

Now the submodule is fixed on the development branch instead of HEAD of master.

Kotlin Code with runOnUiThread

runOnUiThread(
        object : Runnable {
            override fun run() {
                Toast.makeText(applicationContext, "Calling from runOnUiThread()", Toast.LENGTH_SHORT)  
            }
        }
)

I set width as max-content and it worked for me.

width: max-content;

This means a class is redundantly mentioned with a class function. Try removing JSONDeserializer::

If the user should select only one option at once, just remove the "multiple" - make a normal select:

  <select name="mySelect" size="3">
     <option>Foo</option>
     <option>Bar</option>
     <option>Foo Bar</option>
     <option>Bar Foo</option>
  </select>

Fiddle

As you know, MVC supports asynchronous controllers and you should take advantage of it. In case your Controller, performs a lengthy operation, (it might be a disk based I/o or a network call to another remote service), if the request is handled in synchronous manner, the IIS thread is busy the whole time. As a result, the thread is just waiting for the lengthy operation to complete. It can be better utilized by serving other requests while the operation requested in first is under progress. This will help in serving more concurrent requests. Your webservice will be highly scalable and will not easily run into C10k problem. It is a good idea to use async/await for db queries. and yes you can use them as many number of times as you deem fit.

Take a look here for excellent advise.

Scikit-learn (which I recommend using anyways) has it included in the metrics module:

>>> from sklearn.metrics import confusion_matrix
>>> y_true = [0, 1, 2, 0, 1, 2, 0, 1, 2]
>>> y_pred = [0, 0, 0, 0, 1, 1, 0, 2, 2]
>>> confusion_matrix(y_true, y_pred)
array([[3, 0, 0],
       [1, 1, 1],
       [1, 1, 1]])

Use the correct call: strptime is a classmethod of the datetime.datetime class, it's not a function in the datetime module.

self.date = datetime.datetime.strptime(self.d, "%Y-%m-%d")

As mentioned by Jon Clements in the comments, some people do from datetime import datetime, which would bind the datetime name to the datetime class, and make your initial code work.

To identify which case you're facing (in the future), look at your import statements

• import datetime: that's the module (that's what you have right now).
• from datetime import datetime: that's the class.

You need to give some force

Just do push --force.

Here's my hero code. I've faced this problem. And use this code to fix this.

lista = list.sort(lista)

This should be

lista.sort()

The .sort() method is in-place, and returns None. If you want something not in-place, which returns a value, you could use

sorted_list = sorted(lista)

Aside #1: please don't call your lists list. That clobbers the builtin list type.

Aside #2: I'm not sure what this line is meant to do:

print str("value 1a")+str(" + ")+str("value 2")+str(" = ")+str("value 3a ")+str("value 4")+str("\n")

is it simply

print "value 1a + value 2 = value 3a value 4"

? In other words, I don't know why you're calling str on things which are already str.

Aside #3: sometimes you use print("something") (Python 3 syntax) and sometimes you use print "something" (Python 2). The latter would give you a SyntaxError in py3, so you must be running 2.*, in which case you probably don't want to get in the habit or you'll wind up printing tuples, with extra parentheses. I admit that it'll work well enough here, because if there's only one element in the parentheses it's not interpreted as a tuple, but it looks strange to the pythonic eye..

The exception TypeError: 'NoneType' object is not subscriptable happens because the value of lista is actually None. You can reproduce TypeError that you get in your code if you try this at the Python command line:

None[0]

The reason that lista gets set to None is because the return value of list.sort() is None... it does not return a sorted copy of the original list. Instead, as the documentation points out, the list gets sorted in-place instead of a copy being made (this is for efficiency reasons).

If you do not want to alter the original version you can use

other_list = sorted(lista)

To fully satisfy the Date.parse convert string to format dd-mm-YYYY as specified in RFC822, if you use yyyy-mm-dd parse may do a mistakes.

That's because you defined your own version of name for your enum, and getByName doesn't use that.

getByName("COLUMN_HEADINGS") would probably work.

Since Java 8 you can use the argument-less any method and the type argument will get inferred by the compiler:

verify(bar).doStuff(any());

Explanation

The new thing in Java 8 is that the target type of an expression will be used to infer type parameters of its sub-expressions. Before Java 8 only arguments to methods where used for type parameter inference (most of the time).

In this case the parameter type of doStuff will be the target type for any(), and the return value type of any() will get chosen to match that argument type.

This mechanism was added in Java 8 mainly to be able to compile lambda expressions, but it improves type inferences generally.

Primitive types

This doesn't work with primitive types, unfortunately:

public interface IBar {
    void doPrimitiveStuff(int i);
}

verify(bar).doPrimitiveStuff(any()); // Compiles but throws NullPointerException
verify(bar).doPrimitiveStuff(anyInt()); // This is what you have to do instead

The problem is that the compiler will infer Integer as the return value type of any(). Mockito will not be aware of this (due to type erasure) and return the default value for reference types, which is null. The runtime will try to unbox the return value by calling the intValue method on it before passing it to doStuff, and the exception gets thrown.

I did't want to change my source code to add additional observer , so I have written following simple example:

//EVENT DRIVEN OBSERVER PATTERN
public class Publisher
{
    public Publisher()
    {
        var observable = new Observable();
        observable.PublishData("Hello World!");
    }
}

//Server will send data to this class's PublishData method
public class Observable
{
    public event Receive OnReceive;

    public void PublishData(string data)
    {
        //Add all the observer below
        //1st observer
        IObserver iObserver = new Observer1();
        this.OnReceive += iObserver.ReceiveData;
        //2nd observer
        IObserver iObserver2 = new Observer2();
        this.OnReceive += iObserver2.ReceiveData;

        //publish data 
        var handler = OnReceive;
        if (handler != null)
        {
            handler(data);
        }
    }
}

public interface IObserver
{
    void ReceiveData(string data);
}

//Observer example
public class Observer1 : IObserver
{
    public void ReceiveData(string data)
    {
        //sample observers does nothing with data :)
    }
}

public class Observer2 : IObserver
{
    public void ReceiveData(string data)
    {
        //sample observers does nothing with data :)
    }
}

git update-index --chmod=+x gradlew

This command works better especially on non-unix system.

You can easy put ListView in ScrollView! Just need to change height of ListView programmatically, like this:

    ViewGroup.LayoutParams listViewParams = (ViewGroup.LayoutParams)listView.getLayoutParams();
    listViewParams.height = 400;
    listView.requestLayout();

This works perfectly!

First make sure if the URL is actually valid (a string, not empty, good syntax), this is quick to check server side. For example, doing this first could save a lot of time:

if(!$url || !is_string($url) || ! preg_match('/^http(s)?:\/\/[a-z0-9-]+(.[a-z0-9-]+)*(:[0-9]+)?(\/.*)?$/i', $url)){
    return false;
}

Make sure you only fetch the headers, not the body content:

@curl_setopt($ch, CURLOPT_HEADER  , true);  // we want headers
@curl_setopt($ch, CURLOPT_NOBODY  , true);  // we don't need body

For more details on getting the URL status http code I refer to another post I made (it also helps with following redirects):

• How can I check if a URL exists via PHP?

As a whole:

$url = 'http://www.example.com';
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_HEADER, true);    // we want headers
curl_setopt($ch, CURLOPT_NOBODY, true);    // we don't need body
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_TIMEOUT,10);
$output = curl_exec($ch);
$httpcode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);

echo 'HTTP code: ' . $httpcode;

Here's a very easy way without having to deal with the ABC module.

In the __init__ method of the class that you want to be an abstract class, you can check the "type" of self. If the type of self is the base class, then the caller is trying to instantiate the base class, so raise an exception. Here's a simple example:

class Base():
    def __init__(self):
        if type(self) is Base:
            raise Exception('Base is an abstract class and cannot be instantiated directly')
        # Any initialization code
        print('In the __init__  method of the Base class')

class Sub(Base):
    def __init__(self):
        print('In the __init__ method of the Sub class before calling __init__ of the Base class')
        super().__init__()
        print('In the __init__ method of the Sub class after calling __init__ of the Base class')

subObj = Sub()
baseObj = Base()

When run, it produces:

In the __init__ method of the Sub class before calling __init__ of the Base class
In the __init__  method of the Base class
In the __init__ method of the Sub class after calling __init__ of the Base class
Traceback (most recent call last):
  File "/Users/irvkalb/Desktop/Demo files/Abstract.py", line 16, in <module>
    baseObj = Base()
  File "/Users/irvkalb/Desktop/Demo files/Abstract.py", line 4, in __init__
    raise Exception('Base is an abstract class and cannot be instantiated directly')
Exception: Base is an abstract class and cannot be instantiated directly

This shows that you can instantiate a subclass that inherits from a base class, but you cannot instantiate the base class directly.

You need to call the appendChild function to append your new element to an existing element in the DOM.

Case study: GitHub API

https://developer.github.com/v3/#client-errors

Maybe copying from well known APIs is a wise idea:

There are three possible types of client errors on API calls that receive request bodies:

Sending invalid JSON will result in a 400 Bad Request response.

HTTP/1.1 400 Bad Request
Content-Length: 35

{"message":"Problems parsing JSON"}

Sending the wrong type of JSON values will result in a 400 Bad Request response.

HTTP/1.1 400 Bad Request
Content-Length: 40

{"message":"Body should be a JSON object"}

Sending invalid fields will result in a 422 Unprocessable Entity response.

HTTP/1.1 422 Unprocessable Entity
Content-Length: 149

{
  "message": "Validation Failed",
  "errors": [
    {
      "resource": "Issue",
      "field": "title",
      "code": "missing_field"
    }
  ]
}

Dropdown list wont allows multiple item select in dropdown.

If you need , you can use listbox control..

Chrome Dev Tool's "Network" tool now allows you to import HAR files by drag-and-dropping into the window.

The CSS table model is based on the HTML table model http://www.w3.org/TR/CSS21/tables.html

A table is divided into ROWS, and each row contains one or more cells. Cells are children of ROWS, they are NEVER children of columns.

"display: table-column" does NOT provide a mechanism for making columnar layouts (e.g. newspaper pages with multiple columns, where content can flow from one column to the next).

Rather, "table-column" ONLY sets attributes that apply to corresponding cells within the rows of a table. E.g. "The background color of the first cell in each row is green" can be described.

The table itself is always structured the same way it is in HTML.

In HTML (observe that "td"s are inside "tr"s, NOT inside "col"s):

<table ..>
  <col .. />
  <col .. />
  <tr ..>
    <td ..></td>
    <td ..></td>
  </tr>
  <tr ..>
    <td ..></td>
    <td ..></td>
  </tr>
</table>

Corresponding HTML using CSS table properties (Note that the "column" divs do not contain any contents -- the standard does not allow for contents directly in columns):

.mytable {_x000D_
  display: table;_x000D_
}_x000D_
.myrow {_x000D_
  display: table-row;_x000D_
}_x000D_
.mycell {_x000D_
  display: table-cell;_x000D_
}_x000D_
.column1 {_x000D_
  display: table-column;_x000D_
  background-color: green;_x000D_
}_x000D_
.column2 {_x000D_
  display: table-column;_x000D_
}

<div class="mytable">_x000D_
  <div class="column1"></div>_x000D_
  <div class="column2"></div>_x000D_
  <div class="myrow">_x000D_
    <div class="mycell">contents of first cell in row 1</div>_x000D_
    <div class="mycell">contents of second cell in row 1</div>_x000D_
  </div>_x000D_
  <div class="myrow">_x000D_
    <div class="mycell">contents of first cell in row 2</div>_x000D_
    <div class="mycell">contents of second cell in row 2</div>_x000D_
  </div>_x000D_
</div>

OPTIONAL: both "rows" and "columns" can be styled by assigning multiple classes to each row and cell as follows. This approach gives maximum flexibility in specifying various sets of cells, or individual cells, to be styled:

//Useful css declarations, depending on what you want to affect, include:_x000D_
_x000D_
/* all cells (that have "class=mycell") */_x000D_
.mycell {_x000D_
}_x000D_
_x000D_
/* class row1, wherever it is used */_x000D_
.row1 {_x000D_
}_x000D_
_x000D_
/* all the cells of row1 (if you've put "class=mycell" on each cell) */_x000D_
.row1 .mycell {_x000D_
}_x000D_
_x000D_
/* cell1 of row1 */_x000D_
.row1 .cell1 {_x000D_
}_x000D_
_x000D_
/* cell1 of all rows */_x000D_
.cell1 {_x000D_
}_x000D_
_x000D_
/* row1 inside class mytable (so can have different tables with different styles) */_x000D_
.mytable .row1 {_x000D_
}_x000D_
_x000D_
/* all the cells of row1 of a mytable */_x000D_
.mytable .row1 .mycell {_x000D_
}_x000D_
_x000D_
/* cell1 of row1 of a mytable */_x000D_
.mytable .row1 .cell1 {_x000D_
}_x000D_
_x000D_
/* cell1 of all rows of a mytable */_x000D_
.mytable .cell1 {_x000D_
}

<div class="mytable">_x000D_
  <div class="column1"></div>_x000D_
  <div class="column2"></div>_x000D_
  <div class="myrow row1">_x000D_
    <div class="mycell cell1">contents of first cell in row 1</div>_x000D_
    <div class="mycell cell2">contents of second cell in row 1</div>_x000D_
  </div>_x000D_
  <div class="myrow row2">_x000D_
    <div class="mycell cell1">contents of first cell in row 2</div>_x000D_
    <div class="mycell cell2">contents of second cell in row 2</div>_x000D_
  </div>_x000D_
</div>

In today's flexible designs, which use <div> for multiple purposes, it is wise to put some class on each div, to help refer to it. Here, what used to be <tr> in HTML became class myrow, and <td> became class mycell. This convention is what makes the above CSS selectors useful.

PERFORMANCE NOTE: putting class names on each cell, and using the above multi-class selectors, is better performance than using selectors ending with *, such as .row1 * or even .row1 > *. The reason is that selectors are matched last first, so when matching elements are being sought, .row1 * first does *, which matches all elements, and then checks all the ancestors of each element, to find if any ancestor has class row1. This might be slow in a complex document on a slow device. .row1 > * is better, because only the immediate parent is examined. But it is much better still to immediately eliminate most elements, via .row1 .cell1. (.row1 > .cell1 is an even tighter spec, but it is the first step of the search that makes the biggest difference, so it usually isn't worth the clutter, and the extra thought process as to whether it will always be a direct child, of adding the child selector >.)

The key point to take away re performance is that the last item in a selector should be as specific as possible, and should never be *.

Just Follow this to Insert values into database

//Connection String

  con.Open();

sqlQuery = "INSERT INTO [dbo].[Client] ([Client_ID],[Client_Name],[Phone],[Address],[Image]) VALUES('" + txtClientID.Text + "','" + txtClientName.Text + "','" + txtPhoneno.Text + "','" + txtaddress.Text + "',@image)";

                cmd = new SqlCommand(sqlQuery, con);
                cmd.Parameters.Add("@image", SqlDbType.Image);
                cmd.Parameters["@image"].Value = img;
            //img is a byte object
           ** /*MemoryStream ms = new MemoryStream();
            pictureBox1.Image.Save(ms,pictureBox1.Image.RawFormat);
            byte[] img = ms.ToArray();*/**

                cmd.ExecuteNonQuery();
                con.Close();

Interesting question, I tried doing this by just doing a fixed position row, but this way seems to be a much better one. Source at bottom.

You can also use lowercaseString and capitalizedString

ECMAScript 6 introduced the let statement. You can use it in a for statement.

var ids:string = [];

for(let result of this.results){

None of the answers were specific to my problem, so here's how I did it.

This is for Visual Studio 2015 and I had already made a repository on Github.com

If you already have your repository URL copy it and then in visual studio:

• Go to Team Explorer
• Click the "Sync" button
• It should have 3 options listed with "get started" links.
• I chose the "get started" link against "publish to remote repository", which it the bottom one
• A yellow box will appear asking for the URL. Just paste the URL there and click publish.
