You can use Numeric#step.

0.step(30,5) do |num|
  puts "number is #{num}"
end
# >> number is 0
# >> number is 5
# >> number is 10
# >> number is 15
# >> number is 20
# >> number is 25
# >> number is 30

Python does not have these operators, but if you really need them you can write a function having the same functionality.

def PreIncrement(name, local={}):
    #Equivalent to ++name
    if name in local:
        local[name]+=1
        return local[name]
    globals()[name]+=1
    return globals()[name]

def PostIncrement(name, local={}):
    #Equivalent to name++
    if name in local:
        local[name]+=1
        return local[name]-1
    globals()[name]+=1
    return globals()[name]-1

Usage:

x = 1
y = PreIncrement('x') #y and x are both 2
a = 1
b = PostIncrement('a') #b is 1 and a is 2

Inside a function you have to add locals() as a second argument if you want to change local variable, otherwise it will try to change global.

x = 1
def test():
    x = 10
    y = PreIncrement('x') #y will be 2, local x will be still 10 and global x will be changed to 2
    z = PreIncrement('x', locals()) #z will be 11, local x will be 11 and global x will be unaltered
test()

Also with these functions you can do:

x = 1
print(PreIncrement('x'))   #print(x+=1) is illegal!

But in my opinion following approach is much clearer:

x = 1
x+=1
print(x)

Decrement operators:

def PreDecrement(name, local={}):
    #Equivalent to --name
    if name in local:
        local[name]-=1
        return local[name]
    globals()[name]-=1
    return globals()[name]

def PostDecrement(name, local={}):
    #Equivalent to name--
    if name in local:
        local[name]-=1
        return local[name]+1
    globals()[name]-=1
    return globals()[name]+1

I used these functions in my module translating javascript to python.

UPDATE totals 
   SET total = total + 1
WHERE name = 'bill';

If you want to make sure the current value is indeed 203 (and not accidently increase it again) you can also add another condition:

UPDATE totals 
   SET total = total + 1
WHERE name = 'bill'
  AND total = 203;

There is an operator just for this. For example, if I wanted to change a variable i by 3 then:

var someValue = 9;
var Increment  = 3;
for(var i=0;i<someValue;i+=Increment){
//do whatever
}

var someValue = 3;
var Increment  = 3;
for(var i=9;i>someValue;i+=Increment){
//do whatever
}

No, it doesn't, see: R Language Definition: Operators

Here is your solution for the problem,

$letter = array();
for ($i = 'A'; $i !== 'ZZ'; $i++){
        if(ord($i) % 2 != 0)
           $letter[] .= $i;
}
print_r($letter);

You need to get the ASCII value for that character which will solve your problem.

Here is ord doc and working code.

For your requirement, you can do like this,

for ($i = 'A'; $i !== 'ZZ'; ord($i)+$x){
  $letter[] .= $i;
}
print_r($letter);

Here set $x as per your requirement.

You didn't say what you're trying to do, but you hinted at it well enough in the comments to the other answer. I think you're probably looking for an auto increment column

create table logins (userid int auto_increment primary key, 
  username varchar(30), password varchar(30));

then no special code is needed on insert. Just

insert into logins (username, password) values ('user','pass');

The MySQL API has functions to tell you what userid was created when you execute this statement in client code.

Python doesn't support ++, but you can do:

number += 1

The way for loop is processed is as follows

1 First, initialization is performed (i=0)

2 the check is performed (i < n)

3 the code in the loop is executed.

4 the value is incremented

5 Repeat steps 2 - 4

This is the reason why, there is no difference between i++ and ++i in the for loop which has been used.

I came from PHP, where you can increment char (A to B, Z to AA, AA to AB etc.) using ++ operator. I made a simple function which does the same in Python. You can also change list of chars to whatever (lowercase, uppercase, etc.) is your need.

# Increment char (a -> b, az -> ba)
def inc_char(text, chlist = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ'):
    # Unique and sort
    chlist = ''.join(sorted(set(str(chlist))))
    chlen = len(chlist)
    if not chlen:
        return ''
    text = str(text)
    # Replace all chars but chlist
    text = re.sub('[^' + chlist + ']', '', text)
    if not len(text):
        return chlist[0]
    # Increment
    inc = ''
    over = False
    for i in range(1, len(text)+1):
        lchar = text[-i]
        pos = chlist.find(lchar) + 1
        if pos < chlen:
            inc = chlist[pos] + inc
            over = False
            break
        else:
            inc = chlist[0] + inc
            over = True
    if over:
        inc += chlist[0]
    result = text[0:-len(inc)] + inc
    return result

There is a huge difference.

As most of the answers have already pointed out the theory, I would like to point out an easy example:

int x = 1;
//would print 1 as first statement will x = x and then x will increase
int x = x++;
System.out.println(x);

Now let's see ++x:

int x = 1;
//would print 2 as first statement will increment x and then x will be stored
int x = ++x;
System.out.println(x);

You should do it like this:

 for ($i=1; $i <=10; $i+=2) 
{ 
    echo $i.'<br>';
}

"+=" you can increase your variable as much or less you want. "$i+=5" or "$i+=.5"

// const path = 'info.value[0].item'
// const obj = { info: { value: [ { item: 'it works!' } ], randominfo: 3 }  }
// getValue(path, obj)

export const getValue = ( path , obj) => {
  const newPath = path.replace(/\]/g, "")
  const arrayPath = newPath.split(/[\[\.]+/) || newPath;

  const final = arrayPath.reduce( (obj, k) => obj ?  obj[k] : obj, obj)
  return final;
}

To all the great answers, I want to add a small detail:

If You write plugins (e.g. DLLs or .so libraries to be loaded by a CAD system), then static is a life saver that avoids name collisions like this one:

1. The CAD system loads a plugin A, which has a "const int foo = 42;" in it.
2. The system loads a plugin B, which has "const int foo = 23;" in it.
3. As a result, plugin B will use the value 42 for foo, because the plugin loader will realize, that there is already a "foo" with external linkage.

Even worse: Step 3 may behave differently depending on compiler optimization, plugin load mechanism, etc.

I had this issue once with two helper functions (same name, different behaviour) in two plugins. Declaring them static solved the problem.

Here's a clean solution:

function test(str){
    //Note: should be /(abc)|(def)/i if you want it case insensitive
    var pattern = /(abc)|(def)/;
    return !str.match(pattern);
}

Given an instance of the struct, you set the values.

    student thisStudent;
    Console.WriteLine("Please enter StudentId, StudentName, CourseName, Date-Of-Birth");
    thisStudent.s_id = int.Parse(Console.ReadLine());
    thisStudent.s_name = Console.ReadLine();
    thisStudent.c_name = Console.ReadLine();
    thisStudent.s_dob = Console.ReadLine();

Note this code is incredibly fragile, since we aren't checking the input from the user at all. And you aren't clear to the user that you expect each data point to be entered on a separate line.

This answer is for Spring-boot users:

If your JAR was from a Spring-boot project and created using the command mvn package spring-boot:repackage, the above "-cp" method won't work. You will get:

Error: Could not find or load main class your.alternative.class.path

even if you can see the class in the JAR by jar tvf yours.jar.

In this case, run your alternative class by the following command:

java -cp yours.jar -Dloader.main=your.alternative.class.path org.springframework.boot.loader.PropertiesLauncher

As I understood, the Spring-boot's org.springframework.boot.loader.PropertiesLauncher class serves as a dispatching entrance class, and the -Dloader.main parameter tells it what to run.

Reference: https://github.com/spring-projects/spring-boot/issues/20404

You should find out last timestamp values in each group (subquery), and then join this subquery to the table -

SELECT t1.* FROM messages t1
  JOIN (SELECT from_id, MAX(timestamp) timestamp FROM messages GROUP BY from_id) t2
    ON t1.from_id = t2.from_id AND t1.timestamp = t2.timestamp;

You can use AngularJs for this, Its two -way data binding feature will get solution with minimum effort and less code.

<div> <input type="text" name="" ng-model="fbid"><br/> <img src="https://graph.facebook.com/{{fbid}}/picture?type=normal"> </div>

I hope this answers your query.Note: You can use other library as well.

I had this exact same problem with Xampp portable on Windows 10 Home. I went through all the suggestions and none worked. I did get it working with Windows Firewall Settings and an error on my part.

My pen drive was labelled Drive E on my laptop and Drive F on my Desktop. Once I corrected that using disk partition and changed the drive letter to E for my desktop to windows asked for access for the firewall and everything clicked.

The steps to correct the drive letter were: 1. Hit the windows key and type Partition, "create and format harddisks partitions" should be at the top, hit enter 2. Find the drive you are looking for at the top panel and click on it. 3. Right click on it and select change drive letter and path, click okay 4. Now try to start xampp control panel and start Apache and Mysql 5. if you get the windows firewall click allow.

I can't say this will work but it did for me and is what I added to this discussion. I also think it might have been just the firewall did not allow the oither drive letter.

malloc for single chars or integers and calloc for dynamic arrays. ie pointer = ((int *)malloc(sizeof(int)) == NULL), you can do arithmetic within the brackets of malloc but you shouldnt because you should use calloc which has the definition of void calloc(count, size)which means how many items you want to store ie count and size of data ie int , char etc.

I had to apply 100% to both html and body.

Just an update to the answer of @rafa.pereira. Since ggplot2 is part of tidyverse, it makes sense to use the convenient tidyverse functions to get rid of NAs.

library(tidyverse)
airquality %>% 
        drop_na(Ozone) %>%
        ggplot(aes(x = Ozone))+
        geom_bar(stat="bin")

Note that you can also use drop_na() without columns specification; then all the rows with NAs in any column will be removed.

You can open and read .csv file using fopen ,fscanf functions ,but the important thing is to parse the data.Simplest way to parse the data using delimiter.In case of .csv , delimiter is ','.

Suppose your data1.csv file is as follows :

A,45,76,01
B,77,67,02
C,63,76,03
D,65,44,04

you can tokenize data and store in char array and later use atoi() etc function for appropriate conversions

FILE *fp;
char str1[10], str2[10], str3[10], str4[10];

fp = fopen("G:\\data1.csv", "r");
if(NULL == fp)
{
    printf("\nError in opening file.");
    return 0;
}
while(EOF != fscanf(fp, " %[^,], %[^,], %[^,], %s, %s, %s, %s ", str1, str2, str3, str4))
{
    printf("\n%s %s %s %s", str1, str2, str3, str4);
}
fclose(fp);

[^,], ^ -it inverts logic , means match any string that does not contain comma then last , says to match comma that terminated previous string.

One way is to add this to a new c# class or HtmlExtensions class

public static class HtmlExtensions
{
    public static MvcHtmlString Image(this HtmlHelper html, byte[] image)
    {
        var img = String.Format("data:image/jpg;base64,{0}", Convert.ToBase64String(image));
        return new MvcHtmlString("<img src='" + img + "' />");
    }
}

then you can do this in any view

@Html.Image(Model.ImgBytes)

1. Fix the errors in the JSON: http://jsonlint.com/
2. Parse the JSON (since you have tagged the question with JavaScript, use json2.js)
3. Delete the property from the object you created
4. Stringify the object back to JSON.

The auto-indent is based on the current syntax mode. I know that if you are editing Foo.java, then entering a { and hitting Enter indents the following line.

As for tabs, there are two settings. Within Vim, type a colon and then "set tabstop=4" which will set the tabs to display as four spaces. Hit colon again and type "set expandtab" which will insert spaces for tabs.

You can put these settings in a .vimrc (or _vimrc on Windows) in your home directory, so you only have to type them once.

If you want "tag_name" with associated "blogTags_id" use: (PHP > 5.5)

$blogDatas = array_column($your_multi_dim_array, 'tag_name', 'blogTags_id');
echo implode(', ', array_map(function ($k, $v) { return "$k: $v"; }, array_keys($blogDatas), array_values($blogDatas)));

This is may have 2 reasons

1.I found the connection string error in my web.config file i had changed the connection string and its working.

2. Connection string is proper then check with the control panel>services> SQL Server Browser > start or not

Insert the below code in didFinishLaunchingWithOptions() in AppDelegate.m

[[UINavigationBar appearance] setBarTintColor:[UIColor
    colorWithRed:26.0/255.0 green:184.0/255.0 blue:110.0/255.0 alpha:1.0]];

Try this

 $(function(){
   $("input[type='number']").prop('min',1);
   $("input[type='number']").prop('max',10);
});

javascript's parseFloat doesn't take a locale parameter. So you will have to replace , with .

parseFloat('0,04'.replace(/,/, '.')); // 0.04

Question: Is there a simple way to do this in the current release of Python?

Answer: There is no simple (direct) way to do this in the current release of Python.

Reference: Please refer to docs.python.org/2/library/datetime.html, section 8.1.2. timedelta Objects. As we may understand from that, we cannot increment month directly since it is not a uniform time unit.

Plus: If you want first day -> first day and last day -> last day mapping you should handle that separately for different months.

In my case, this has been resolved by going to control panel > java > security > then add url in the exception site list. Then apply. Test again the site and it should now allow you to run the local java.

Use:

#include <windows.h>

Sleep(sometime_in_millisecs); // Note uppercase S

And here's a small example that compiles with MinGW and does what it says on the tin:

#include <windows.h>
#include <stdio.h>

int main() {
    printf( "starting to sleep...\n" );
    Sleep(3000); // Sleep three seconds
    printf("sleep ended\n");
}

When you get a value from client make and that a value for example.

var current_text = document.getElementById('user_text').value;
        var http = new XMLHttpRequest();
        http.onreadystatechange = function () {

            if (http.readyState == 4 &&  http.status == 200 ){
                var response = http.responseText;
              document.getElementById('server_response').value = response;
                console.log(response.value);


            }

This website has a concise tutorial on how to use SQL Server Management Studio. As you will see you can open a "Query Window", paste your script and run it. It does not allow you to execute scripts by using the file path. However, you can do this easily by using the command line (cmd.exe):

sqlcmd -S .\SQLExpress -i SqlScript.sql

Where SqlScript.sql is the script file name located at the current directory. See this Microsoft page for more examples

I don't know of any out-of-the-box way to achieve this. As you say, this is not how SharePoint lists are intended used. It might work to create a custom site column displaying the path to the document, as this might be used in a filter. Have never tried it, though.

You can simulate it with using varargs, however then you should check it for too many arguments.

public void foo(int param1, int ... param2)
{
   int param2_
   if(param2.length == 0)
      param2_ = 2
   else if(para2.length == 1)
      param2_ = param2[0]
   else
      throw new TooManyArgumentsException(); // user provided too many arguments,

   // rest of the code
}

However this approach is not a good way of doing this, therefore it is better to use overloading.

You are right the urllib and urllib2 packages have been split into urllib.request , urllib.parse and urllib.error packages in Python 3.x. The latter packages do not exist in Python 2.x

From documentation -

The urllib module has been split into parts and renamed in Python 3 to urllib.request, urllib.parse, and urllib.error.

From urllib2 documentation -

The urllib2 module has been split across several modules in Python 3 named urllib.request and urllib.error.

So I am pretty sure the code you downloaded has been written for Python 3.x , since they are using a library that is only present in Python 3.x .

There is a urllib package in python, but it does not have the request subpackage. Also, lets assume you do lots of work and somehow make request subpackage available in Python 2.x .

There is a very very high probability that you will run into more issues, there is lots of incompatibility between Python 2.x and Python 3.x , in the end you would most probably end up rewriting atleast half the code from github (and most probably reading and understanding the complete code from there).

Even then there may be other bugs arising from the fact that some of the implementation details changed between Python 2.x to Python 3.x (As an example - list comprehension got its own namespace in Python 3.x)

You are better off trying to download and use Python 3 , than trying to make code written for Python 3.x compatible with Python 2.x

Don't forget to edit the file. Open file /etc/default/tomcat7 and change

#AUTHBIND=no

to

AUTHBIND=yes

then restart.

If key is present table.put(key, val) will just overwrite the value else it'll create a new entry. Poof! and you are done. :)

you can get the value from a map by using key is table.get(key); That's about it

you can store the Path into string variable like

string s = choofdlog.FileName;

The ubuntu package name is qt5-default, not qt.

Creating a new base collection for each eloquent collection the merge works for me.

$foo = collect(Foo::all());
$bar = collect(Bar::all());
$merged = $foo->merge($bar);

In this case don't have conflits by its primary keys.

Another short addition to the above mentioned situations is:

• Always unsubscribe, when new values in the subscribed stream is no more required or don't matter, it will result in way less number of triggers and increase in performance in a few cases. Cases such as components where the subscribed data/event no more exists or a new subscription to an all new stream is required (refresh, etc.) is a good example for unsubscription.

Extremely important if using console.log() in production:

if you end up releasing console.log() commands to production you need to put in some kind of fix for IE - because console is only defined when in F12 debugging mode.

if (typeof console == "undefined") {
    this.console = { log: function (msg) { alert(msg); } };
}

[obviously remove the alert(msg); statement once you've verified it works]

See also 'console' is undefined error for Internet Explorer for other solutions and more details

If there is space between the letters of the font, you need to use quote.

font-family:"Calibri (Body)";

Plugin eregex.vim handles Perl-style non-greedy operators *? and +?

Write-Host can concatenate like this too:

Write-Host $assoc.Id" - "$assoc.Name" - "$assoc.Owner

This is the simplest way, IMHO.

No need to go far, according to Google Maps, the best is FLOAT(10,6) for lat and lng.

Try this:

var div = document.getElementById('divID');

div.innerHTML += 'Extra stuff';

I like Imagemagick. http://www.imagemagick.org/script/api.php

That's HTML, but yes, you can bang pretty much any selectors you like together.

#x.y { }

(And the HTML is fine too)

I've had this issue and none of the suggestions I found anywhere helped, unfortunately. The good news, however, is that the latest versions work without any hacks! I'm referring to Windows 7 host here.

genymotion-2.5.4.exe

VirtualBox-5.0.5-102814-Win.exe (download from test builds)

Edit: This stopped working again after updates so I gave up on Genymotion. The new Android emulator in SDK performs just as well, has great functionaly, and works without hiccups.

Missing Context file location in configuration can cause this, one approach to solve this:

• Specifying Context file location in ContextConfiguration

like:

@ContextConfiguration(locations = { "classpath:META-INF/your-spring-context.xml" })

More details

@RunWith( SpringJUnit4ClassRunner.class )
@ContextConfiguration(locations = { "classpath:META-INF/your-spring-context.xml" })
public class UserServiceTest extends AbstractJUnit4SpringContextTests {}

Significant differences that have not really been adequately mentioned here:

• map keeps iterators to all elements stable, in C++17 you can even move elements from one map to the other without invalidating iterators to them (and if properly implemented without any potential allocation).
• map timings for single operations are typically more consistent since they never need large allocations.
• unordered_map using std::hash as implemented in the libstdc++ is vulnerable to DoS if fed with untrusted input (it uses MurmurHash2 with a constant seed - not that seeding would really help, see https://emboss.github.io/blog/2012/12/14/breaking-murmur-hash-flooding-dos-reloaded/).
• Being ordered enables efficient range searches, e.g. iterate over all elements with key = 42.

This is a MultiThreading Issue and Using Properly Synchronized Blocks This can be prevented. Without putting extra things on UI Thread and causing loss of responsiveness of app.

I also faced the same. And as the most accepted answer suggests making change to adapter data from UI Thread can solve the issue. That will work but is a quick and easy solution but not the best one.

As you can see for a normal case. Updating data adapter from background thread and calling notifyDataSetChanged in UI thread works.

This illegalStateException arises when a ui thread is updating the view and another background thread changes the data again. That moment causes this issue.

So if you will synchronize all the code which is changing the adapter data and making notifydatasetchange call. This issue should be gone. As gone for me and i am still updating the data from background thread.

Here is my case specific code for others to refer.

My loader on the main screen loads the phone book contacts into my data sources in the background.

    @Override
    public Void loadInBackground() {
        Log.v(TAG, "Init loadings contacts");
        synchronized (SingleTonProvider.getInstance()) {
            PhoneBookManager.preparePhoneBookContacts(getContext());
        }
    }

This PhoneBookManager.getPhoneBookContacts reads contact from phonebook and fills them in the hashmaps. Which is directly usable for List Adapters to draw list.

There is a button on my screen. That opens a activity where these phone numbers are listed. If i directly setAdapter over the list before the previous thread finishes its work which is fast naviagtion case happens less often. It pops up the exception .Which is title of this SO question. So i have to do something like this in the second activity.

My loader in the second activity waits for first thread to complete. Till it shows a progress bar. Check the loadInBackground of both the loaders.

Then it creates the adapter and deliver it to the activity where on ui thread i call setAdapter.

That solved my issue.

This code is a snippet only. You need to change it to compile well for you.

@Override
public Loader<PhoneBookContactAdapter> onCreateLoader(int arg0, Bundle arg1) {
    return new PhoneBookContactLoader(this);

Since the desired page will be called from a different domain you need to return jsonp instead of a json.

$.get("http://theSource", {callback : "?" }, "jsonp",  function(data) {
    $('#summary').text(data.result);
});

I had this problem too but preferred to prevent negative margins hacks, so I put a

<div class="supercontainer"></div>

around it all which has paddings instead of margins. Of course this means more divitis but it's probably the cleanest way to do get this done properly.

I wanted something where I have access to base64 value to store into a list and for me adding event listener worked. You just need the FileReader which will read the image blob and return the base64 in the result.

createImageFromBlob(image: Blob) {
    const reader = new FileReader();
    const supportedImages = []; // you can also refer to some global variable
    reader.addEventListener(
      'load',
      () => {
        // reader.result will have the required base64 image
        const base64data = reader.result;
        supportedImages.push(base64data); // this can be a reference to global variable and store the value into that global list so as to use it in the other part
      },
      false
    );
    // The readAsDataURL method is used to read the contents of the specified Blob or File.
    if (image) {
      reader.readAsDataURL(image);
    }
 }

Final part is the readAsDataURL which is very important is being used to read the content of the specified Blob

But if one has to substitute, then the following thing works:

:%s/\n/\r\|\-\r/g

In the above, every next line is substituted with next line, and then |- and again a new line. This is used in wiki tables.

If the text is as follows:

line1
line2
line3

It is changed to

line1
|-
line2
|-
line3

I have read that while the underlying chips are essentially the same, the design of the board is different.

Gamers want performance, and tend to favor overclocking and other things to get high frame rates but which maybe burn out the hardware occasionally.

Businesses want reliability, and tend to favor underclocking so they can be sure that their people can keep working.

Also, I have read that the quadro boards use ECC memory.

If you don't know what ECC memory is about: it's a [relatively] well known fact that sometimes memory "flips bits (experiences errors)". This does not happen too often, but is an unavoidable consequence of the underlying physics of the memory cards and the world we live in. ECC memory adds a small percentage to the cost and a small penalty to the performance and has enough redundancy to correct occasional errors and to detect (but not correct) somewhat rarer errors. Gamers don't care about that kind of accuracy because for gamers those are just very rare visual glitches. Companies do care about that kind of accuracy because those glitches would wind up as glitches in their products or else would require more double or triple checking (which winds up being a 2x or 3x performance penalty for some part of their business).

Another issue I have read about has to do with hooking up the graphics card to third party hardware. In other words: sending the images to another card or to another machine instead of to the screen. Most gamers are just using canned software that doesn't have any use for such capabilities. Companies that use that kind of thing get orders of magnitude performance gains from the more direct connections.

if you are trying DB first then be sure that your table has primary key

There's an answer above which says "cursors are the SLOWEST way to access data inside SQL Server... cursors are over thirty times slower than set based alternatives."

This statement may be true under many circumstances, but as a blanket statement it's problematic. For example, I've made good use of cursors in situations where I want to perform an update or delete operation affecting many rows of a large table which is receiving constant production reads. Running a stored procedure which does these updates one row at a time ends up being faster than set-based operations, because the set-based operation conflicts with the read operation and ends up causing horrific locking problems (and may kill the production system entirely, in extreme cases).

In the absence of other database activity, set-based operations are universally faster. In production systems, it depends.

This simplistic version also works.

public void UploadMultipart(byte[] file, string filename, string contentType, string url)
{
    var webClient = new WebClient();
    string boundary = "------------------------" + DateTime.Now.Ticks.ToString("x");
    webClient.Headers.Add("Content-Type", "multipart/form-data; boundary=" + boundary);
    var fileData = webClient.Encoding.GetString(file);
    var package = string.Format("--{0}\r\nContent-Disposition: form-data; name=\"file\"; filename=\"{1}\"\r\nContent-Type: {2}\r\n\r\n{3}\r\n--{0}--\r\n", boundary, filename, contentType, fileData);

    var nfile = webClient.Encoding.GetBytes(package);

    byte[] resp = webClient.UploadData(url, "POST", nfile);
}

Add any extra required headers if needed.

this is the answer async at console app in C#?

anything whereever in the console app never use await but instead use theAsyncMethod().GetAwaiter().GetResult();,

example

var result = await HttpClientInstance.SendAsync(message);

becomes

var result = HttpClientInstance.SendAsync(message).GetAwaiter().GetResult();

You can run Rundll32.exe for IE Options control panel applet and achieve following tasks.

window.location.href returns the location of the current page.

top.location.href (which is an alias of window.top.location.href) returns the location of the topmost window in the window hierarchy. If a window has no parent, top is a reference to itself (in other words, window === window.top).

top is useful both when you're dealing with frames and when dealing with windows which have been opened by other pages. For example, if you have a page called test.html with the following script:

var newWin=window.open('about:blank','test','width=100,height=100');
newWin.document.write('<script>alert(top.location.href);</script>');

The resulting alert will have the full path to test.html – not about:blank, which is what window.location.href would return.

To answer your question about redirecting, go with window.location.assign(url);

In short, services set to Automatic will start during the boot process, while services set to start as Delayed will start shortly after boot.

Starting your service Delayed improves the boot performance of your server and has security benefits which are outlined in the article Adriano linked to in the comments.

Update: "shortly after boot" is actually 2 minutes after the last "automatic" service has started, by default. This can be configured by a registry key, according to Windows Internals and other sources (3,4).

The registry keys of interest (At least in some versions of windows) are:

• HKLM\SYSTEM\CurrentControlSet\services\<service name>\DelayedAutostart will have the value 1 if delayed, 0 if not.
• HKLM\SYSTEM\CurrentControlSet\services\AutoStartDelay or HKLM\SYSTEM\CurrentControlSet\Control\AutoStartDelay (on Windows 10): decimal number of seconds to wait, may need to create this one. Applies globally to all Delayed services.

$cRepo = $em->getRepository('KaleLocationBundle:Country');

// Leave the first array blank
$countries = $cRepo->findBy(array(), array('name'=>'asc'));

Note, from 2015 onwards, just use backticks for templating

https://stackoverflow.com/a/37245773/294884

let a = `hello ${name}`    // NOTE!!!!!!!! ` not ' or "

Note that it is a backtick, not a quote.

If you want to have something similar, you could create a function:

function parse(str) {
    var args = [].slice.call(arguments, 1),
        i = 0;

    return str.replace(/%s/g, () => args[i++]);
}

Usage:

s = parse('hello %s, how are you doing', my_name);

This is only a simple example and does not take into account different kinds of data types (like %i, etc) or escaping of %s. But I hope it gives you some idea. I'm pretty sure there are also libraries out there which provide a function like this.

NOTE: if you're trying to load a non-ILOnly assembly, then

Assembly.Load(block)

won't work, and an exception will be thrown: more details

I overcame this by creating a temporary file, and using

Assembly.LoadFile(dllFile)

This is actually pretty easy to fix and doesn't take any coding:

1.Click on the Plots tab above the console. 2.Then at the top right corner of the plots screen click on the options button. 3.Lastly uncheck the "Mute inline plotting" button

Now re-run your script and your graphs should show up in the console.

Cheers.

The root of the problem is that you are unknowingly using the Frame class from the ttk package rather than from the tkinter package. The one from ttk does not support the background option.

This is the main reason why you shouldn't do global imports -- you can overwrite the definition of classes and commands.

I recommend doing imports like this:

import tkinter as tk
import ttk

Then you prefix the widgets with either tk or ttk :

f1 = tk.Frame(..., bg=..., fg=...)
f2 = ttk.Frame(..., style=...)

It then becomes instantly obvious which widget you are using, at the expense of just a tiny bit more typing. If you had done this, this error in your code would never have happened.

From my "get.all" script, which I invoke each morning to run a bunch of subsequent "get.XXX" jobs to refresh the software that I track. Some of them are auto-quitting. Others require more interaction once the get has finished (like asking to build emacs).

I faced off the same problem when working with self-signed certs and client cert auth on .NET Core 2.2 and Docker Linux containers. Everything worked fine on my dev Windows machine, but in Docker I got such error:

System.Security.Authentication.AuthenticationException: The remote certificate is invalid according to the validation procedure

Fortunately, the certificate was generated using a chain. Of course, you can always ignore this solution and use the above solutions.

So here is my solution:

1. I saved the certificate using Chrome on my computer in P7B format.

2. Convert certificate to PEM format using this command:
   openssl pkcs7 -inform DER -outform PEM -in <cert>.p7b -print_certs > ca_bundle.crt

3. Open the ca_bundle.crt file and delete all Subject recordings, leaving a clean file. Example below:

    -----BEGIN CERTIFICATE-----
    _BASE64 DATA_
    -----END CERTIFICATE-----
    -----BEGIN CERTIFICATE-----
    _BASE64 DATA_
    -----END CERTIFICATE-----
    -----BEGIN CERTIFICATE-----
    _BASE64 DATA_
    -----END CERTIFICATE-----

4. Put these lines to the Dockerfile (in the final steps):

    # Update system and install curl and ca-certificates
    RUN apt-get update && apt-get install -y curl && apt-get install -y ca-certificates
    # Copy your bundle file to the system trusted storage
    COPY ./ca_bundle.crt /usr/local/share/ca-certificates/ca_bundle.crt
    # During docker build, after this line you will get such output: 1 added, 0 removed; done.
    RUN update-ca-certificates

5. In the app:

        SendTimeout = new TimeSpan(0, 1, 0),

            }
        }
    };
    var client = new MyWSClient(binding, address);
    client.ClientCredentials.ClientCertificate.Certificate = GetClientCertificate("clientCert.pfx", "passwordForClientCert");
    // Client certs must be installed
    client.ClientCredentials.ServiceCertificate.SslCertificateAuthentication = new X509ServiceCertificateAuthentication
    {
        CertificateValidationMode = X509CertificateValidationMode.ChainTrust,
        TrustedStoreLocation = StoreLocation.LocalMachine,
        RevocationMode = X509RevocationMode.NoCheck
    };

GetClientCertificate method:

private static X509Certificate2 GetClientCertificate(string clientCertName, string password)
{
    //Create X509Certificate2 object from .pfx file
    byte[] rawData = null;
    using (var f = new FileStream(Path.Combine(AppContext.BaseDirectory, clientCertName), FileMode.Open, FileAccess.Read))
    {
        var size = (int)f.Length;
        var rawData = new byte[size];
        f.Read(rawData, 0, size);
        f.Close();
    }
    return new X509Certificate2(rawData, password);
}

Simple is better, one variable, one function :)

   ...acc,
   [value]: (acc[value] || 0) + 1
}), {});

For anyone seeing this after upgrading their Windows 10 (post April 2018 update), the DPI Scaling Override setting has moved into a dedicated window:

with this code, the id will not appear on the link

    document.querySelectorAll('a[href^="#"]').forEach(anchor => {
        anchor.addEventListener('click', function (e) {
            e.preventDefault();

            document.querySelector(this.getAttribute('href')).scrollIntoView({
                behavior: 'smooth'
            });
        });
    });

Unfortunately PL/SQL doesn't have IF EXISTS operator like SQL Server. But you can do something like this:

begin
  for x in ( select count(*) cnt
               from dual 
              where exists (
                select 1 from courseoffering co
                  join co_enrolment ce on ce.co_id = co.co_id
                 where ce.s_regno = 403 
                   and ce.coe_completionstatus = 'C' 
                   and co.c_id = 803 ) )
  loop
        if ( x.cnt = 1 ) 
        then
           dbms_output.put_line('exists');
        else 
           dbms_output.put_line('does not exist');
        end if;
  end loop;
end;

I did the test using java 8 It wont matter the order the builder always takes 0 milliseconds and the concat between 26 and 33 milliseconds under and iteration of a 1000 concatenation

Hope it helps try it with your ide

public void count() {

        String result = "";

        StringBuilder builder = new StringBuilder();

        long millis1 = System.currentTimeMillis(),
            millis2;

        for (int i = 0; i < 1000; i++) {
            builder.append("hello world this is the concat vs builder test enjoy");
        }

        millis2 = System.currentTimeMillis();

        System.out.println("Diff: " + (millis2 - millis1));

        millis1 = System.currentTimeMillis();

        for (int i = 0; i < 1000; i++) {
            result += "hello world this is the concat vs builder test enjoy";
        }

        millis2 = System.currentTimeMillis();

        System.out.println("Diff: " + (millis2 - millis1));
    }

Clarifications to the preceding posts:

References are NOT a guarantee of getting a non-null pointer. (Though we often treat them as such.)

While horrifically bad code, as in take you out behind the woodshed bad code, the following will compile & run: (At least under my compiler.)

bool test( int & a)
{
  return (&a) == (int *) NULL;
}

int
main()
{
  int * i = (int *)NULL;
  cout << ( test(*i) ) << endl;
};

The real issue I have with references lies with other programmers, henceforth termed IDIOTS, who allocate in the constructor, deallocate in the destructor, and fail to supply a copy constructor or operator=().

Suddenly there's a world of difference between foo(BAR bar) and foo(BAR & bar). (Automatic bitwise copy operation gets invoked. Deallocation in destructor gets invoked twice.)

Thankfully modern compilers will pick up this double-deallocation of the same pointer. 15 years ago, they didn't. (Under gcc/g++, use setenv MALLOC_CHECK_ 0 to revisit the old ways.) Resulting, under DEC UNIX, in the same memory being allocated to two different objects. Lots of debugging fun there...

More practically:

• References hide that you are changing data stored someplace else.
• It's easy to confuse a Reference with a Copied object.
• Pointers make it obvious!

First store the table in a view, then select columns from that view into a new table.

// Create a table with abitrary columns for use with the example
System.Data.DataTable table = new System.Data.DataTable();
for (int i = 1; i <= 11; i++)
    table.Columns.Add("col" + i.ToString());

// Load the table with contrived data
for (int i = 0; i < 100; i++)
{
    System.Data.DataRow row = table.NewRow();
    for (int j = 0; j < 11; j++)
        row[j] = i.ToString() + ", " + j.ToString();
    table.Rows.Add(row);
}

// Create the DataView of the DataTable
System.Data.DataView view = new System.Data.DataView(table);
// Create a new DataTable from the DataView with just the columns desired - and in the order desired
System.Data.DataTable selected = view.ToTable("Selected", false, "col1", "col2", "col6", "col7", "col3");

Used the sample data to test this method I found: Create ADO.NET DataView showing only selected Columns

There is a way to store multiple solutions in one instance of VS.

Attempt the following steps:

1. File > Open > Project/Solution
2. This will bring up the open project window, notice at the bottom where it says options, select add to solution

3. Then select the file you want to add and click open
4. This will then add the solution to your project. You still won't be able to run the same project in a single instance of VS, but you can have all your code organized in one place.

NOTE: This worked for Visual Studio 2013 Professional

The differences in speed in a for- and a foreach-loop are tiny when you're looping through common structures like arrays, lists, etc, and doing a LINQ query over the collection is almost always slightly slower, although it's nicer to write! As the other posters said, go for expressiveness rather than a millisecond of extra performance.

What hasn't been said so far is that when a foreach loop is compiled, it is optimised by the compiler based on the collection it is iterating over. That means that when you're not sure which loop to use, you should use the foreach loop - it will generate the best loop for you when it gets compiled. It's more readable too.

Another key advantage with the foreach loop is that if your collection implementation changes (from an int array to a List<int> for example) then your foreach loop won't require any code changes:

foreach (int i in myCollection)

The above is the same no matter what type your collection is, whereas in your for loop, the following will not build if you changed myCollection from an array to a List:

for (int i = 0; i < myCollection.Length, i++)

The excellent joda-time library is almost always a better choice than Java's Date or Calendar classes. Here's a few examples:

DateTime aDate = new DateTime(year, month, day, hour, minute, second);
DateTime anotherDate = new DateTime(anotherYear, anotherMonth, anotherDay, ...);
if (aDate.isAfter(anotherDate)) {...}
DateTime yearFromADate = aDate.plusYears(1);

As per the docs, OkHttp version 3 replaced FormEncodingBuilder with FormBody and FormBody.Builder(), so the old examples won't work anymore.

Form and Multipart bodies are now modeled. We've replaced the opaque FormEncodingBuilder with the more powerful FormBody and FormBody.Builder combo.

Similarly we've upgraded MultipartBuilder into MultipartBody, MultipartBody.Part, and MultipartBody.Builder.

So if you're using OkHttp 3.x try the following example:

OkHttpClient client = new OkHttpClient();

RequestBody formBody = new FormBody.Builder()
        .add("message", "Your message")
        .build();
Request request = new Request.Builder()
        .url("http://www.foo.bar/index.php")
        .post(formBody)
        .build();

try {
    Response response = client.newCall(request).execute();

    // Do something with the response.
} catch (IOException e) {
    e.printStackTrace();
}

Now I got the solution to the problem which I have faced: The TFS remembered the prior password when I got logged in by using my mobile VPN.

Solution:

Resetting the account that I used to connect using VPN

I was wondering how to do this myself; it seems Gmail has since silently implemented this feature. I created the following filter:

Matches: subject:([test])
Do this: Skip Inbox

And then I sent a message with the subject

[test] foo

And the message was archived! So it seems all that is necessary is to create a filter for the subject prefix you wish to handle.

With xidel:

curl <...> | xidel - -se '$json'

xidel can probably retrieve the JSON for you as well.

As an alternative, if you just want to install make, you can use the chocolatey package manager to install gnu make by using

choco install make -y

This deals with any path issues that you might have.

Just put this in the first line of your script :

#!/usr/bin/env python

Make the file executable with

chmod +x myfile.py

Execute with

./myfile.py

I had similar issue. I resolved it with just CSS.

Basically Object-fit: cover was not working in IE and it was taking 100% width and 100% height and aspect ratio was distorted. In other words image zooming effect wasn't there which I was seeing in chrome.

The approach I took was to position the image inside the container with absolute and then place it right at the centre using the combination:

position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);

Once it is in the centre, I give to the image,

// For vertical blocks (i.e., where height is greater than width)
height: 100%;
width: auto;

// For Horizontal blocks (i.e., where width is greater than height)
height: auto;
width: 100%;

This makes the image get the effect of Object-fit:cover.

Here is a demonstration of the above logic.

https://jsfiddle.net/furqan_694/s3xLe1gp/

This logic works in all browsers.

I had the same problem, and didn´t want to rewrite the code, so I wrote a function to modify the code and create the inline declarated events:

function compile(qSel){
    var matches = [];
    var match = null;
    var c = 0;

    var html = $(qSel).html();
    var pattern = /(<(.*?)on([a-zA-Z]+)\s*=\s*('|")(.*)('|")(.*?))(>)/mg;

    while (match = pattern.exec(html)) {
        var arr = [];
        for (i in match) {
            if (!isNaN(i)) {
                arr.push(match[i]);
            }
        }
        matches.push(arr);
    }
    var items_with_events = [];
    var compiledHtml = html;

    for ( var i in matches ){
        var item_with_event = {
            custom_id : "my_app_identifier_"+i,
            code : matches[i][5],
            on : matches[i][3],
        };
        items_with_events.push(item_with_event);
        compiledHtml = compiledHtml.replace(/(<(.*?)on([a-zA-Z]+)\s*=\s*('|")(.*)('|")(.*?))(>)/m, "<$2 custom_id='"+item_with_event.custom_id+"' $7 $8");
    }

    $(qSel).html(compiledHtml);

    for ( var i in items_with_events ){
        $("[custom_id='"+items_with_events[i].custom_id+"']").bind(items_with_events[i].on, function(){
            eval(items_with_events[i].code);
        });
    }
}

$(document).ready(function(){
    compile('#content');
})

This should remove all inline events from the selected node, and recreate them with jquery instead.

.NET 4.0 allows primary interop assemblies (or rather, the bits of it that you need) to be embedded into your assembly so that you don't need to deploy them alongside your application.

For whatever reason, this assembly can't be embedded - but it sounds like that's not a problem for you. Just open the Properties tab for the assembly in Visual Studio 2010 and set "Embed Interop Types" to "False".

EDIT: See also Michael Gustus's answer, removing the Class suffix from the types you're using.

For kotlin I use the following

val fcmtoken = FirebaseMessaging.getInstance().token.await()

and for the extension functions

public suspend fun <T> Task<T>.await(): T {
    // fast path
    if (isComplete) {
        val e = exception
        return if (e == null) {
            if (isCanceled) {
                throw CancellationException("Task $this was cancelled normally.")
            } else {
                @Suppress("UNCHECKED_CAST")
                result as T
            }
        } else {
            throw e
        }
    }

    return suspendCancellableCoroutine { cont ->
        addOnCompleteListener {
            val e = exception
            if (e == null) {
                @Suppress("UNCHECKED_CAST")
                if (isCanceled) cont.cancel() else cont.resume(result as T)
            } else {
                cont.resumeWithException(e)
            }
        }
    }
}

I got this answer from the book Programming iOS 7, section Bar Position and Bar Metrics

If a navigation bar or toolbar — or a search bar (discussed earlier in this chapter) — is to occupy the top of the screen, the iOS 7 convention is that its height should be increased to underlap the transparent status bar. To make this possible, iOS 7 introduces the notion of a bar position.

UIBarPositionTopAttached

Specifies that the bar is at the top of the screen, as well as its containing view. Bars with this position draw their background extended upwards, allowing their background content to show through the status bar. Available in iOS 7.0 and later.

change your file permissions .. like this

first check who owns the directory

ls -la /usr/local/lib/node_modules

it is denying access because the node_module folder is owned by root

drwxr-xr-x   3 root    wheel  102 Jun 24 23:24 node_modules

so this needs to be changed by changing root to your user but first run command below to check your current user How do I get the name of the active user via the command line in OS X?

id -un

OR

whoami

then change owner

sudo chown -R [owner]:[owner] /usr/local/lib/node_modules

OR

sudo chown -R ownerName: /usr/local/lib/node_modules

OR

sudo chown -R $USER /usr/local/lib/node_modules

I am sure you would've already found your answer... here is the solution I derived at.

That's my CSS.

.field, .actions {
    margin-bottom: 15px;
  }
  .field label {
    float: left;
    width: 30%;
    text-align: right;
    padding-right: 10px;
    margin: 5px 0px 5px 0px;
  }
  .field input {
    width: 70%;
    margin: 0px;
  }

And my HTML...

<h1>New customer</h1>
<div class="container form-center">
    <form accept-charset="UTF-8" action="/customers" class="new_customer" id="new_customer" method="post">
    <div style="margin:0;padding:0;display:inline"></div>

  <div class="field">
    <label for="customer_first_name">First name</label>
    <input class="form-control" id="customer_first_name" name="customer[first_name]" type="text" />
  </div>
  <div class="field">
    <label for="customer_last_name">Last name</label>
    <input class="form-control" id="customer_last_name" name="customer[last_name]" type="text" />
  </div>
  <div class="field">
    <label for="customer_addr1">Addr1</label>
    <input class="form-control" id="customer_addr1" name="customer[addr1]" type="text" />
  </div>
  <div class="field">
    <label for="customer_addr2">Addr2</label>
    <input class="form-control" id="customer_addr2" name="customer[addr2]" type="text" />
  </div>
  <div class="field">
    <label for="customer_city">City</label>
    <input class="form-control" id="customer_city" name="customer[city]" type="text" />
  </div>
  <div class="field">
    <label for="customer_pincode">Pincode</label>
    <input class="form-control" id="customer_pincode" name="customer[pincode]" type="text" />
  </div>
  <div class="field">
    <label for="customer_homephone">Homephone</label>
    <input class="form-control" id="customer_homephone" name="customer[homephone]" type="text" />
  </div>
  <div class="field">
    <label for="customer_mobile">Mobile</label>
    <input class="form-control" id="customer_mobile" name="customer[mobile]" type="text" />
  </div>
  <div class="actions">
    <input class="btn btn-primary btn-large btn-block" name="commit" type="submit" value="Create Customer" />
  </div>
</form>
</div>

Actually, I think you might be confused by how you should run a script.

If you use sh to run a script, say, sh ./run2.sh, even if the embedded script ends with exit, your terminal window will still remain.

However if you use . or source, your terminal window will exit/close as well when subscript ends.

for more detail, please refer to What is the difference between using sh and source?

• In C++:

Just use std::vector<char> which keep the (dynamic) size for you. (Bonus, memory management for free).

Or std::array<char, 10> which keep the (static) size.

• In pure C:

Create a structure to keep the info, something like:

typedef struct {
    char* ptr;
    int size;
} my_array;

my_array malloc_array(int size)
{
    my_array res;
    res.ptr = (char*) malloc(size);
    res.size = size;
    return res;
}

void free_array(my_array array)
{
    free(array.ptr);
}

Following Docker's DOC site: Manage Docker as a non-root user

1) Create Docker Group

sudo groupadd docker 

2) Make user belong to docker group to get the group's privileges.

sudo usermod -aG docker $USER

Check whether the DOCKER_HOST environment variable is set for your shell.

env | grep DOCKER_HOST

If it exists,

unset DOCKER_HOST

Then this should work:

docker run hello-world

I had a similar problem. Data in a worksheet I needed to save as a separate CSV file.

Here's my code behind a command button

Private Sub cmdSave()
    Dim sFileName As String
    Dim WB As Workbook

    Application.DisplayAlerts = False

    sFileName = "MyFileName.csv"
    'Copy the contents of required sheet ready to paste into the new CSV
    Sheets(1).Range("A1:T85").Copy 'Define your own range

    'Open a new XLS workbook, save it as the file name
    Set WB = Workbooks.Add
    With WB
        .Title = "MyTitle"
        .Subject = "MySubject"
        .Sheets(1).Select
        ActiveSheet.Paste
        .SaveAs "MyDirectory\" & sFileName, xlCSV
        .Close
    End With

    Application.DisplayAlerts = True
End Sub

This works for me :-)

You might want to have a look at joda time, which is a little easier to use than the java native date tools, and provides many common date patterns pre-built.

In response to comments, more detail:

To do this using Joda time, you need two DateTimeFormatters - one for your input format to parse your input and one for your output format to print your output. Your input format is an ISO standard format, so Joda time's ISODateTimeFormat class has a static method with a parser for it already: dateHourMinuteSecondMillis. Your output format isn't one they have a pre-built formatter for, so you'll have to make one yourself using DateTimeFormat. I think DateTimeFormat.forPattern("mm/dd/yyyy kk:mm:ss.SSS"); should do the trick. Once you have your two formatters, call the parseDateTime() method on the input format and the print method on the output format to get your result, as a string.

Putting it together should look something like this (warning, untested):

DateTimeFormatter input = ISODateTimeFormat.dateHourMinuteSecondMillis();
DateTimeFormatter output = DateTimeFormat.forPattern("mm/dd/yyyy kk:mm:ss.SSS");
String outputFormat = output.print( input.parseDate(inputFormat) );

http://msdn.microsoft.com/en-us/library/system.net.sockets.socket.remoteendpoint.aspx

You can then call the IPEndPoint..::.Address method to retrieve the remote IPAddress, and the IPEndPoint..::.Port method to retrieve the remote port number.

More from the link (fixed up alot heh):

Socket s;

IPEndPoint remoteIpEndPoint = s.RemoteEndPoint as IPEndPoint;
IPEndPoint localIpEndPoint = s.LocalEndPoint as IPEndPoint;

if (remoteIpEndPoint != null)
{
    // Using the RemoteEndPoint property.
    Console.WriteLine("I am connected to " + remoteIpEndPoint.Address + "on port number " + remoteIpEndPoint.Port);
}

if (localIpEndPoint != null)
{
    // Using the LocalEndPoint property.
    Console.WriteLine("My local IpAddress is :" + localIpEndPoint.Address + "I am connected on port number " + localIpEndPoint.Port);
}

Here's a different approach. The heart of it was created by turning on the Macro Recorder and filtering the columns per your specifications. Then there's a bit of code to copy the results. It will run faster than looping through each row and column:

Sub FilterAndCopy()
Dim LastRow As Long

Sheets("Sheet2").UsedRange.Offset(0).ClearContents
With Worksheets("Sheet1")
    .Range("$A:$E").AutoFilter
    .Range("$A:$E").AutoFilter field:=1, Criteria1:="#N/A"
    .Range("$A:$E").AutoFilter field:=2, Criteria1:="=String1", Operator:=xlOr, Criteria2:="=string2"
    .Range("$A:$E").AutoFilter field:=3, Criteria1:=">0"
    .Range("$A:$E").AutoFilter field:=5, Criteria1:="Number"
    LastRow = .Range("A" & .Rows.Count).End(xlUp).Row
    .Range("A1:A" & LastRow).SpecialCells(xlCellTypeVisible).EntireRow.Copy _
            Destination:=Sheets("Sheet2").Range("A1")
End With
End Sub

As a side note, your code has more loops and counter variables than necessary. You wouldn't need to loop through the columns, just through the rows. You'd then check the various cells of interest in that row, much like you did.

Another thing that messed things up for me was using localhost instead of 127.0.0.1 or vice versa. Apparently, JavaScript can't handle requests from one to the other.

You are not allowed to use the concatenation operator with the case statement. One possible solution is to use a variable within the process:

process(b0,b1,b2,b3)
   variable bcat : std_logic_vector(0 to 3);
begin
   bcat := b0 & b1 & b2 & b3;
   case bcat is
      when "0000" => x <= 1;
      when others => x <= 2;
   end case;
end process;

I made a small directive to listen for file input changes.

View JSFiddle

view.html:

<input type="file" custom-on-change="uploadFile">

controller.js:

app.controller('myCtrl', function($scope){
    $scope.uploadFile = function(event){
        var files = event.target.files;
    };
});     

directive.js:

app.directive('customOnChange', function() {
  return {
    restrict: 'A',
    link: function (scope, element, attrs) {
      var onChangeHandler = scope.$eval(attrs.customOnChange);
      element.on('change', onChangeHandler);
      element.on('$destroy', function() {
        element.off();
      });

    }
  };
});

Try this one. You can strip just ' and " with:

$FileName = str_replace(array('\'', '"'), '', $UserInput); 

Put your jQuery function in

$(document).ready(function(){

});

It's surely solved.

Transition is more like an animation.

div.sicon a {
    background:-moz-radial-gradient(left, #ffffff 24%, #cba334 88%);
    transition: background 0.5s linear;
    -moz-transition: background 0.5s linear; /* Firefox 4 */
    -webkit-transition: background 0.5s linear; /* Safari and Chrome */
    -o-transition: background 0.5s linear; /* Opera */
    -ms-transition: background 0.5s linear; /* Explorer 10 */
}

So you need to invoke that animation with an action.

div.sicon a:hover {
    background:-moz-radial-gradient(left, #cba334 24%, #ffffff 88%);
}

Also check for browser support and if you still have some problem with whatever you're trying to do! Check css-overrides in your stylesheet and also check out for behavior: ***.htc css hacks.. there may be something overriding your transition!

If you want to first take mean on the combination of ['cluster', 'org'] and then take mean on cluster groups, you can use:

In [59]: (df.groupby(['cluster', 'org'], as_index=False).mean()
            .groupby('cluster')['time'].mean())
Out[59]:
cluster
1          15
2          54
3           6
Name: time, dtype: int64

If you want the mean of cluster groups only, then you can use:

In [58]: df.groupby(['cluster']).mean()
Out[58]:
              time
cluster
1        12.333333
2        54.000000
3         6.000000

You can also use groupby on ['cluster', 'org'] and then use mean():

In [57]: df.groupby(['cluster', 'org']).mean()
Out[57]:
               time
cluster org
1       a    438886
        c        23
2       d      9874
        h        34
3       w         6

I created jquery.backgroundSize.js: a 1.5K jquery plugin that can be used as a IE8 fallback for "cover" and "contain" values. Have a look at the demo.

You can try this:

var theString = "This is a string.";_x000D_
console.log(theString.split("is").length - 1);

Its clearly explained here. Thanks to Eugen Paraschiv.

Circular dependency is a design smell, either fix it or use @Lazy for the dependency which causes problem to workaround it.

You may write to a file using fs (file system) module.

Here is an example of how you may do it:

const fs = require('fs');

const writeToFile = (fileName, callback) => {
  fs.open(fileName, 'wx', (error, fileDescriptor) => {
    if (!error && fileDescriptor) {
      // Do something with the file here ...
      fs.writeFile(fileDescriptor, newData, (error) => {
        if (!error) {
          fs.close(fileDescriptor, (error) => {
            if (!error) {
              callback(false);
            } else {
              callback('Error closing the file');
            }
          });
        } else {
          callback('Error writing to new file');
        }
      });
    } else {
      callback('Could not create new file, it may already exists');
    }
  });
};

You might also want to get rid of this callback-inside-callback code structure by useing Promises and async/await statements. This will make asynchronous code structure much more flat. For doing that there is a handy util.promisify(original) function might be utilized. It allows us to switch from callbacks to promises. Take a look at the example with fs functions below:

// Dependencies.
const util = require('util');
const fs = require('fs');

// Promisify "error-back" functions.
const fsOpen = util.promisify(fs.open);
const fsWrite = util.promisify(fs.writeFile);
const fsClose = util.promisify(fs.close);

// Now we may create 'async' function with 'await's.
async function doSomethingWithFile(fileName) {
  const fileDescriptor = await fsOpen(fileName, 'wx');

  // Do something with the file here...

  await fsWrite(fileDescriptor, newData);
  await fsClose(fileDescriptor);
}

In my case I had a mismatch between the connection string name I was registering in the context's constructor vs the name in my web.config. Simple mistake caused by copy and paste :D

    public DataContext()
        : base(nameOrConnectionString: "ConnStringName")
    {
        Database.SetInitializer<DataContext>(null);
    }

Old thread I know but I am sort of new to Java and discover one of it's strange things. I have used String.replaceAll() but get unpredictable results.

Something like this mess up the string:

sUrl = sUrl.replaceAll( "./", "//").replaceAll( "//", "/");

So I designed this function to get around the weird problem:

//String.replaceAll does not work OK, that's why this function is here
public String strReplace( String s1, String s2, String s ) 
{
    if((( s == null ) || (s.length() == 0 )) || (( s1 == null ) || (s1.length() == 0 )))
     { return s; }

   while( (s != null) && (s.indexOf( s1 ) >= 0) )
    { s = s.replace( s1, s2 ); }
  return s;
}

Which make you able to do:

sUrl=this.strReplace("./", "//", sUrl );
sUrl=this.strReplace( "//", "/", sUrl );

Set oShell = WScript.CreateObject("WSCript.shell")
oShell.run "cmd cd /d C:dir_test\file_test & sanity_check_env.bat arg1"

You can simply import by

mysqlimport --ignore-lines=1 --lines-terminated-by='\n' --fields-terminated-by=',' --fields-enclosed-by='"' --verbose --local -uroot -proot db_name csv_import.csv

Note: Csv File name and Table name should be same

Setting RetainSameConnection property to True for Excel manager Worked for me .

After allocating DateFormatter you need to give the formatted string then you can convert as string like this way

var date = Date()
let formatter = DateFormatter()
formatter.dateFormat = "yyyy-MM-dd HH:mm:ss"
let myString = formatter.string(from: date)
let yourDate: Date? = formatter.date(from: myString)
formatter.dateFormat = "dd-MMM-yyyy"
let updatedString = formatter.string(from: yourDate!)
print(updatedString)

Quoting the spec

15.4 Array Objects

Array objects give special treatment to a certain class of property names. A property name P (in the form of a String value) is an array index if and only if ToString(ToUint32(P)) is equal to P and ToUint32(P) is not equal to 2^32-1. A property whose property name is an array index is also called an element. Every Array object has a length property whose value is always a nonnegative integer less than 2^32. The value of the length property is numerically greater than the name of every property whose name is an array index; whenever a property of an Array object is created or changed, other properties are adjusted as necessary to maintain this invariant. Specifically, whenever a property is added whose name is an array index, the length property is changed, if necessary, to be one more than the numeric value of that array index; and whenever the length property is changed, every property whose name is an array index whose value is not smaller than the new length is automatically deleted. This constraint applies only to own properties of an Array object and is unaffected by length or array index properties that may be inherited from its prototypes.

And here's a table for typeof

To add some background, there are two data types in JavaScript:

1. Primitive Data types - This includes null, undefined, string, boolean, number and object.
2. Derived data types/Special Objects - These include functions, arrays and regular expressions. And yes, these are all derived from "Object" in JavaScript.

An object in JavaScript is similar in structure to the associative array/dictionary seen in most object oriented languages - i.e., it has a set of key-value pairs.

An array can be considered to be an object with the following properties/keys:

1. Length - This can be 0 or above (non-negative).
2. The array indices. By this, I mean "0", "1", "2", etc are all properties of array object.

Hope this helped shed more light on why typeof Array returns an object. Cheers!

You can just sum and set param axis=1 to sum the rows, this will ignore none numeric columns:

In [91]:

df = pd.DataFrame({'a': [1,2,3], 'b': [2,3,4], 'c':['dd','ee','ff'], 'd':[5,9,1]})
df['e'] = df.sum(axis=1)
df
Out[91]:
   a  b   c  d   e
0  1  2  dd  5   8
1  2  3  ee  9  14
2  3  4  ff  1   8

If you want to just sum specific columns then you can create a list of the columns and remove the ones you are not interested in:

In [98]:

col_list= list(df)
col_list.remove('d')
col_list
Out[98]:
['a', 'b', 'c']
In [99]:

df['e'] = df[col_list].sum(axis=1)
df
Out[99]:
   a  b   c  d  e
0  1  2  dd  5  3
1  2  3  ee  9  5
2  3  4  ff  1  7

You can create a PrintStream wrapping around your OutputStream and then just call it's print(String):

final OutputStream os = new FileOutputStream("/tmp/out");
final PrintStream printStream = new PrintStream(os);
printStream.print("String");
printStream.close();

The colon is a built-in command that does nothing, but returns 0 (success). Thus, it's shorter (and faster) than calling an actual command to do the same thing.

If You Use Namespaces

In my own findings, I think it's good to mention that you (as far as I can tell) must declare the full namespace path of a class.

MyClass.php

namespace com\company\lib;
class MyClass {
}

index.php

namespace com\company\lib;

//Works fine
$i = new MyClass();

$cname = 'MyClass';

//Errors
//$i = new $cname;

//Works fine
$cname = "com\\company\\lib\\".$cname;
$i = new $cname;

MyModel.objects.get(pk=1).delete()

this will raise exception if the object with specified primary key doesn't exist because at first it tries to retrieve the specified object.

MyModel.objects.filter(pk=1).delete()

this wont raise exception if the object with specified primary key doesn't exist and it directly produces the query

DELETE FROM my_models where id=1

Like that. Except char hi=hello; should be char hi=hello.charAt(0). (Don't forget your break; statements).

You want the NPGSQL library. Your only other alternative is ODBC.

In C++:

#include <limits>

then use

int imin = std::numeric_limits<int>::min(); // minimum value
int imax = std::numeric_limits<int>::max();

std::numeric_limits is a template type which can be instantiated with other types:

float fmin = std::numeric_limits<float>::min(); // minimum positive value
float fmax = std::numeric_limits<float>::max();

In C:

#include <limits.h>

then use

int imin = INT_MIN; // minimum value
int imax = INT_MAX;

or

#include <float.h>

float fmin = FLT_MIN;  // minimum positive value
double dmin = DBL_MIN; // minimum positive value

float fmax = FLT_MAX;
double dmax = DBL_MAX;

This is how I got it to work:

(since I ran into this today)

Be careful when using ES2015 fat arrow syntax:

This will fail :

it('accesses the network', done => {

  this.timeout(500); // will not work

  // *this* binding refers to parent function scope in fat arrow functions!
  // i.e. the *this* object of the describe function

  done();
});

EDIT: Why it fails:

As @atoth mentions in the comments, fat arrow functions do not have their own this binding. Therefore, it's not possible for the it function to bind to this of the callback and provide a timeout function.

Bottom line: Don't use arrow functions for functions that need an increased timeout.

For vector graphics, ImageMagick has both a render resolution and an output size that are independent of each other.

Try something like

convert -density 300 image.eps -resize 1024x1024 image.jpg

Which will render your eps at 300dpi. If 300 * width > 1024, then it will be sharp. If you render it too high though, you waste a lot of memory drawing a really high-res graphic only to down sample it again. I don't currently know of a good way to render it at the "right" resolution in one IM command.

The order of the arguments matters! The -density X argument needs to go before image.eps because you want to affect the resolution that the input file is rendered at.

This is not super obvious in the manpage for convert, but is hinted at:

dd() dumps the variable and ends the execution of the script ⁽¹⁾, so surrounding it with <pre> tags will leave it broken. Just use good ol' var_dump() (or print_r() if you know it's an array)

Route::get('/', function()
{
    echo '<pre>';
    var_dump(User::all());
    echo '</pre>';
    //exit;  <--if you want
});

Update:

I think you could format down what's shown by having Laravel convert the model object to array:

Route::get('/', function()
{
    echo '<pre>';
    $user = User::where('person_id', '=', 1);
    var_dump($user->toArray()); // <---- or toJson()
    echo '</pre>';
    //exit;  <--if you want
});

(1) For the record, this is the implementation of dd():

function dd()
{
    array_map(function($x) { var_dump($x); }, func_get_args()); die;
}

Judging from other answers, it seems this might be find's fault.

However you can do it this way instead:

find . * | grep -P "[a-f0-9\-]{36}\.jpg"

You might have to tweak the grep a bit and use different options depending on what you want but it works.

I think about it in terms of information. Any problem consists of learning a certain number of bits.

Your basic tool is the concept of decision points and their entropy. The entropy of a decision point is the average information it will give you. For example, if a program contains a decision point with two branches, it's entropy is the sum of the probability of each branch times the log₂ of the inverse probability of that branch. That's how much you learn by executing that decision.

For example, an if statement having two branches, both equally likely, has an entropy of 1/2 * log(2/1) + 1/2 * log(2/1) = 1/2 * 1 + 1/2 * 1 = 1. So its entropy is 1 bit.

Suppose you are searching a table of N items, like N=1024. That is a 10-bit problem because log(1024) = 10 bits. So if you can search it with IF statements that have equally likely outcomes, it should take 10 decisions.

That's what you get with binary search.

Suppose you are doing linear search. You look at the first element and ask if it's the one you want. The probabilities are 1/1024 that it is, and 1023/1024 that it isn't. The entropy of that decision is 1/1024*log(1024/1) + 1023/1024 * log(1024/1023) = 1/1024 * 10 + 1023/1024 * about 0 = about .01 bit. You've learned very little! The second decision isn't much better. That is why linear search is so slow. In fact it's exponential in the number of bits you need to learn.

Suppose you are doing indexing. Suppose the table is pre-sorted into a lot of bins, and you use some of all of the bits in the key to index directly to the table entry. If there are 1024 bins, the entropy is 1/1024 * log(1024) + 1/1024 * log(1024) + ... for all 1024 possible outcomes. This is 1/1024 * 10 times 1024 outcomes, or 10 bits of entropy for that one indexing operation. That is why indexing search is fast.

Now think about sorting. You have N items, and you have a list. For each item, you have to search for where the item goes in the list, and then add it to the list. So sorting takes roughly N times the number of steps of the underlying search.

So sorts based on binary decisions having roughly equally likely outcomes all take about O(N log N) steps. An O(N) sort algorithm is possible if it is based on indexing search.

I've found that nearly all algorithmic performance issues can be looked at in this way.

There are lots of solutions:

b = Arrays.copyOf(a, a.length);

Which allocates a new array, copies over the elements of a, and returns the new array.

Or

b = new int[a.length];
System.arraycopy(a, 0, b, 0, b.length);

Which copies the source array content into a destination array that you allocate yourself.

Or

b = a.clone();

which works very much like Arrays.copyOf(). See this thread.

Or the one you posted, if you reverse the direction of the assignment in the loop:

b[i] = a[i]; // NOT a[i] = b[i];

1. Right click on properties of Console Application.
2. Check Target framework
3. If it is .Net framework 4.0 Client Profile then change it to .Net Framework 4.0

It works now

I think I like this solution:

import getpass
getpass.getpass("Press Enter to Continue")

It hides whatever the user types in, which helps clarify that input is not used here.

But be mindful on the OS X platform. It displays a key which may be confusing.

Probably the best solution would be to do something similar to the getpass module yourself, without making a read -s call. Maybe making the foreground color match the background?

updated for Swift 3 :

used below code to make UIButton corner round:

 yourButtonOutletName.layer.cornerRadius = 0.3 *
        yourButtonOutletName.frame.size.height

I was able to get this to work. I will describe my application and the integration test here.

The Example Application

The example application has two classes and one interface that are relevant to this problem:

1. The application context configuration class
2. The entity class
3. The repository interface

These classes and the repository interface are described in the following.

The source code of the PersistenceContext class looks as follows:

import com.jolbox.bonecp.BoneCPDataSource;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.PropertySource;
import org.springframework.core.env.Environment;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;
import org.springframework.orm.jpa.JpaTransactionManager;
import org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean;
import org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter;
import org.springframework.transaction.annotation.EnableTransactionManagement;

import javax.sql.DataSource;
import java.util.Properties;

@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(basePackages = "net.petrikainulainen.spring.datajpa.todo.repository")
@PropertySource("classpath:application.properties")
public class PersistenceContext {

    protected static final String PROPERTY_NAME_DATABASE_DRIVER = "db.driver";
    protected static final String PROPERTY_NAME_DATABASE_PASSWORD = "db.password";
    protected static final String PROPERTY_NAME_DATABASE_URL = "db.url";
    protected static final String PROPERTY_NAME_DATABASE_USERNAME = "db.username";

    private static final String PROPERTY_NAME_HIBERNATE_DIALECT = "hibernate.dialect";
    private static final String PROPERTY_NAME_HIBERNATE_FORMAT_SQL = "hibernate.format_sql";
    private static final String PROPERTY_NAME_HIBERNATE_HBM2DDL_AUTO = "hibernate.hbm2ddl.auto";
    private static final String PROPERTY_NAME_HIBERNATE_NAMING_STRATEGY = "hibernate.ejb.naming_strategy";
    private static final String PROPERTY_NAME_HIBERNATE_SHOW_SQL = "hibernate.show_sql";

    private static final String PROPERTY_PACKAGES_TO_SCAN = "net.petrikainulainen.spring.datajpa.todo.model";

    @Autowired
    private Environment environment;

    @Bean
    public DataSource dataSource() {
        BoneCPDataSource dataSource = new BoneCPDataSource();

        dataSource.setDriverClass(environment.getRequiredProperty(PROPERTY_NAME_DATABASE_DRIVER));
        dataSource.setJdbcUrl(environment.getRequiredProperty(PROPERTY_NAME_DATABASE_URL));
        dataSource.setUsername(environment.getRequiredProperty(PROPERTY_NAME_DATABASE_USERNAME));
        dataSource.setPassword(environment.getRequiredProperty(PROPERTY_NAME_DATABASE_PASSWORD));

        return dataSource;
    }

    @Bean
    public JpaTransactionManager transactionManager() {
        JpaTransactionManager transactionManager = new JpaTransactionManager();

        transactionManager.setEntityManagerFactory(entityManagerFactory().getObject());

        return transactionManager;
    }

    @Bean
    public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
        LocalContainerEntityManagerFactoryBean entityManagerFactoryBean = new LocalContainerEntityManagerFactoryBean();

        entityManagerFactoryBean.setDataSource(dataSource());
        entityManagerFactoryBean.setJpaVendorAdapter(new HibernateJpaVendorAdapter());
        entityManagerFactoryBean.setPackagesToScan(PROPERTY_PACKAGES_TO_SCAN);

        Properties jpaProperties = new Properties();
        jpaProperties.put(PROPERTY_NAME_HIBERNATE_DIALECT, environment.getRequiredProperty(PROPERTY_NAME_HIBERNATE_DIALECT));
        jpaProperties.put(PROPERTY_NAME_HIBERNATE_FORMAT_SQL, environment.getRequiredProperty(PROPERTY_NAME_HIBERNATE_FORMAT_SQL));
        jpaProperties.put(PROPERTY_NAME_HIBERNATE_HBM2DDL_AUTO, environment.getRequiredProperty(PROPERTY_NAME_HIBERNATE_HBM2DDL_AUTO));
        jpaProperties.put(PROPERTY_NAME_HIBERNATE_NAMING_STRATEGY, environment.getRequiredProperty(PROPERTY_NAME_HIBERNATE_NAMING_STRATEGY));
        jpaProperties.put(PROPERTY_NAME_HIBERNATE_SHOW_SQL, environment.getRequiredProperty(PROPERTY_NAME_HIBERNATE_SHOW_SQL));

        entityManagerFactoryBean.setJpaProperties(jpaProperties);

        return entityManagerFactoryBean;
    }
}

Let's assume that we have a simple entity called Todo which source code looks as follows:

@Entity
@Table(name="todos")
public class Todo {

    public static final int MAX_LENGTH_DESCRIPTION = 500;
    public static final int MAX_LENGTH_TITLE = 100;

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long id;

    @Column(name = "description", nullable = true, length = MAX_LENGTH_DESCRIPTION)
    private String description;

    @Column(name = "title", nullable = false, length = MAX_LENGTH_TITLE)
    private String title;

    @Version
    private long version;
}

Our repository interface has a single method called updateTitle() which updates the title of a todo entry. The source code of the TodoRepository interface looks as follows:

import net.petrikainulainen.spring.datajpa.todo.model.Todo;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.Modifying;
import org.springframework.data.jpa.repository.Query;
import org.springframework.data.repository.query.Param;

import java.util.List;

public interface TodoRepository extends JpaRepository<Todo, Long> {

    @Modifying
    @Query("Update Todo t SET t.title=:title WHERE t.id=:id")
    public void updateTitle(@Param("id") Long id, @Param("title") String title);
}

The updateTitle() method is not annotated with the @Transactional annotation because I think that it is best to use a service layer as a transaction boundary.

The Integration Test

The Integration Test uses DbUnit, Spring Test and Spring-Test-DBUnit. It has three components which are relevant to this problem:

1. The DbUnit dataset which is used to initialize the database into a known state before the test is executed.
2. The DbUnit dataset which is used to verify that the title of the entity is updated.
3. The integration test.

These components are described with more details in the following.

The name of the DbUnit dataset file which is used to initialize the database to known state is toDoData.xml and its content looks as follows:

<dataset>
    <todos id="1" description="Lorem ipsum" title="Foo" version="0"/>
    <todos id="2" description="Lorem ipsum" title="Bar" version="0"/>
</dataset>

The name of the DbUnit dataset which is used to verify that the title of the todo entry is updated is called toDoData-update.xml and its content looks as follows (for some reason the version of the todo entry was not updated but the title was. Any ideas why?):

<dataset>
    <todos id="1" description="Lorem ipsum" title="FooBar" version="0"/>
    <todos id="2" description="Lorem ipsum" title="Bar" version="0"/>
</dataset>

The source code of the actual integration test looks as follows (Remember to annotate the test method with the @Transactional annotation):

import com.github.springtestdbunit.DbUnitTestExecutionListener;
import com.github.springtestdbunit.TransactionDbUnitTestExecutionListener;
import com.github.springtestdbunit.annotation.DatabaseSetup;
import com.github.springtestdbunit.annotation.ExpectedDatabase;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.annotation.Rollback;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.TestExecutionListeners;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.support.DependencyInjectionTestExecutionListener;
import org.springframework.test.context.support.DirtiesContextTestExecutionListener;
import org.springframework.test.context.transaction.TransactionalTestExecutionListener;
import org.springframework.transaction.annotation.Transactional;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = {PersistenceContext.class})
@TestExecutionListeners({ DependencyInjectionTestExecutionListener.class,
        DirtiesContextTestExecutionListener.class,
        TransactionalTestExecutionListener.class,
        DbUnitTestExecutionListener.class })
@DatabaseSetup("todoData.xml")
public class ITTodoRepositoryTest {

    @Autowired
    private TodoRepository repository;

    @Test
    @Transactional
    @ExpectedDatabase("toDoData-update.xml")
    public void updateTitle_ShouldUpdateTitle() {
        repository.updateTitle(1L, "FooBar");
    }

After I run the integration test, the test passes and the title of the todo entry is updated. The only problem which I am having is that the version field is not updated. Any ideas why?

I undestand that this description is a bit vague. If you want to get more information about writing integration tests for Spring Data JPA repositories, you can read my blog post about it.

libconfig is very easy, and what's better, it uses a pseudo json notation for better readability.

Easy to install on Ubuntu: sudo apt-get install libconfig++8-dev

and link: -lconfig++

I don't believe there is one.

bool is just an alias for System.Boolean

Just set your desire country timezone and You can easily show in html it update using SetInteval() function after every one minut. function formatAMPM() manage 12 hour format and AM/PM time display.

$(document).ready(function(){
        var pakTime = new Date().toLocaleString("en-US", {timeZone: "Asia/Karachi"});
        pakTime = new Date(pakTime);

        var libyaTime = new Date().toLocaleString("en-US", {timeZone: "Africa/Tripoli"});
        libyaTime = new Date(libyaTime);



         document.getElementById("pak").innerHTML = "PAK  "+formatAMPM(pakTime);
         document.getElementById("ly").innerHTML = "LY   " +formatAMPM(libyaTime);

        setInterval(function(today) {
            var pakTime = new Date().toLocaleString("en-US", {timeZone: "Asia/Karachi"});
            pakTime = new Date(pakTime);

            var libyaTime = new Date().toLocaleString("en-US", {timeZone: "Africa/Tripoli"});
            libyaTime = new Date(libyaTime);


           document.getElementById("pak").innerHTML = "PAK  "+formatAMPM(pakTime);
           document.getElementById("ly").innerHTML = "LY  " +formatAMPM(libyaTime);

        },10000);

         function formatAMPM(date) {
            var hours = date.getHours();
            var minutes = date.getMinutes();
            var ampm = hours >= 12 ? 'pm' : 'am';
            hours = hours % 12;
            hours = hours ? hours : 12; // the hour '0' should be '12'
            minutes = minutes < 10 ? '0'+minutes : minutes;
            var strTime = hours + ':' + minutes + ' ' + ampm;
            return strTime;
        }


    });

This is a few months late, but I have created PR#6251 with matplotlib to add a new PercentFormatter class. With this class you just need one line to reformat your axis (two if you count the import of matplotlib.ticker):

import ...
import matplotlib.ticker as mtick

ax = df['myvar'].plot(kind='bar')
ax.yaxis.set_major_formatter(mtick.PercentFormatter())

PercentFormatter() accepts three arguments, xmax, decimals, symbol. xmax allows you to set the value that corresponds to 100% on the axis. This is nice if you have data from 0.0 to 1.0 and you want to display it from 0% to 100%. Just do PercentFormatter(1.0).

The other two parameters allow you to set the number of digits after the decimal point and the symbol. They default to None and '%', respectively. decimals=None will automatically set the number of decimal points based on how much of the axes you are showing.

Update

PercentFormatter was introduced into Matplotlib proper in version 2.1.0.

Assuming all of these columns are int, then the first thing to sort out is converting one or more of them to a better data type - int division performs truncation, so anything less than 100% would give you a result of 0:

select (100.0 * (SPGI09_EARLY_OVER_T – SPGI09_OVER_WK_EARLY_ADJUST_T)) / (SPGI09_EARLY_OVER_T + SPGR99_LATE_CM_T  + SPGR99_ON_TIME_Q)
from 
CSPGI09_OVERSHIPMENT 

Here, I've mutiplied one of the numbers by 100.0 which will force the result of the calculation to be done with floats rather than ints. By choosing 100, I'm also getting it ready to be treated as a %.

I was also a little confused by your bracketing - I think I've got it correct - but you had brackets around single values, and then in other places you had a mix of operators (- and /) at the same level, and so were relying on the precedence rules to define which operator applied first.

If you are using php then just please use the php symlink function, like following:

symlink('/home/username/projectname/storage/app/public', '/home/username/public_html/storage')

change the username and project name to the right names.

When you define you own html form then you have to include authentication token string ,that should be sent to controller for security reasons. If you use rails form helper to generate the authenticity token is added to form as follow.

<form accept-charset="UTF-8" action="/login/signin" method="post">
  <div style="display:none">
    <input name="utf8" type="hidden" value="&#x2713;" />
    <input name="authenticity_token" type="hidden" value="x37DrAAwyIIb7s+w2+AdoCR8cAJIpQhIetKRrPgG5VA=">
  </div>
    ...
</form>

So the solution to the problem is either to add authenticity_token field or use rails form helpers rather then compromising security etc.

I know this is quite a few years later but here are some interesting plugins. I have not tried either of these yet so YMMV.

https://github.com/mikelue/vim-maven-plugin

https://github.com/vim-scripts/maven-ide

EDIT: Oh an BTW, i've tried eclim off and on, but the reason I like vim is its lightness. Executing eclipse even on headless mode is just too much mental lifting for me.

EDIT2: I've been using playframework lately and this will probably work with maven builds too:

• For compiling, you can configure VIM's make to run maven or in my case, run a build script, tee that to a file.

  autocmd Filetype java setl makeprg=play_compile
  autocmd Filetype java setl efm=%A\ %#[error]\ %f:%l:\ %m,%-Z\ %#[error]\ %p^,%-C%.%#
  

"play_compile" is just a compile script. It uses SBT so Maven should work just fine here. Even direct javac will work. This way, you can use VIM"s quickfix buffer (:cnext, :clist: cprev, etc).

• For jumping around the classes, I use ctrl-p. Its beautiful. Use it. Faster than eclipse in jumping around files.

• For jumping around methods, I use tagsearch with exuberant c-tags. Jump into method declarations by using ctrl-]. Go back using Ctrl-o. Doesnt work as good as eclipse, but it works good enough.

• I use supertab for code completion. Javacomplete is pretty slow, so I stick with omni-complete. Again, not as accurate as eclipse, but its fast and works good enough for me.

As shaishab roy says, in the cheat sheet you can find the answer.

But in his answer, the given response was :

{path: '/home/...', name: 'Home', component: HomeComponent}
{path: '/', redirectTo: ['Home']},
{path: '/user/...', name: 'User', component: UserComponent},
{path: '/404', name: 'NotFound', component: NotFoundComponent},

{path: '/*path', redirectTo: ['NotFound']}

For some reasons, it doesn't works on my side, so I tried instead :

{path: '/**', redirectTo: ['NotFound']}

and it works. Be careful and don't forget that you need to put it at the end, or else you will often have the 404 error page ;).

It would most likely process them sequentially (why not just test it). But you can also do this:

1. make a file called curlrequests.sh

2. put it in a file like thus:

   curl http://example.com/?update_=1
   curl http://example.com/?update_=3
   curl http://example.com/?update_=234
   curl http://example.com/?update_=65
   

3. save the file and make it executable with chmod:

   chmod +x curlrequests.sh
   

4. run your file:

   ./curlrequests.sh
   

or

   /path/to/file/curlrequests.sh

As a side note, you can chain requests with &&, like this:

   curl http://example.com/?update_=1 && curl http://example.com/?update_=2 && curl http://example.com?update_=3`

And execute in parallel using &:

   curl http://example.com/?update_=1 & curl http://example.com/?update_=2 & curl http://example.com/?update_=3

Use GNU passwd stdin flag.

From the man page:

   --stdin
          This option is used to indicate that passwd should read the new password from standard input, which can be a pipe.

NOTE: Only for root user.

Example

$ adduser foo 
$ echo "NewPass" |passwd foo --stdin
Changing password for user foo.
passwd: all authentication tokens updated successfully.

Alternatively you can use expect, this simple code will do the trick:

#!/usr/bin/expect
spawn passwd foo
expect "password:"
send "Xcv15kl\r"
expect "Retype new password:"
send "Xcv15kl\r"
interact

Results

$ ./passwd.xp 
spawn passwd foo
Changing password for user foo.
New password: 
Retype new password: 
passwd: all authentication tokens updated successfully.

You should Remember about TERNARY operator

:

so your code will be like this,

render(){
    return (
        <div>
            <Element1/>
            <Element2/>
            // note: code does not work here
            { 
               this.props.hasImage ?  // if has image
               <MyImage />            // return My image tag 
               :
               <OtherElement/>        // otherwise return other element  

             }
        </div>
    )
}

It's simple-

SELECT empname,
       empid,
       (SELECT COUNT (profileid)
          FROM profile
         WHERE profile.empid = employee.empid)
           AS number_of_profiles
  FROM employee;

It is even simpler when you use a table join like this:

  SELECT e.empname, e.empid, COUNT (p.profileid) AS number_of_profiles
    FROM employee e LEFT JOIN profile p ON e.empid = p.empid
GROUP BY e.empname, e.empid;

Explanation for the subquery:

Essentially, a subquery in a select gets a scalar value and passes it to the main query. A subquery in select is not allowed to pass more than one row and more than one column, which is a restriction. Here, we are passing a count to the main query, which, as we know, would always be only a number- a scalar value. If a value is not found, the subquery returns null to the main query. Moreover, a subquery can access columns from the from clause of the main query, as shown in my query where employee.empid is passed from the outer query to the inner query.

Edit:

When you use a subquery in a select clause, Oracle essentially treats it as a left join (you can see this in the explain plan for your query), with the cardinality of the rows being just one on the right for every row in the left.

Explanation for the left join

A left join is very handy, especially when you want to replace the select subquery due to its restrictions. There are no restrictions here on the number of rows of the tables in either side of the LEFT JOIN keyword.

For more information read Oracle Docs on subqueries and left join or left outer join.

Use this command inside you Dockerfile to keep the container running in your K8s cluster:

ES6 introduce template strings for concatenation. Template Strings use back-ticks (``) rather than the single or double quotes we're used to with regular strings. A template string could thus be written as follows:

// Simple string substitution
let name = "Brendan";
console.log(`Yo, ${name}!`);

// => "Yo, Brendan!"

var a = 10;
var b = 10;
console.log(`JavaScript first appeared ${a+b} years ago. Crazy!`);

//=> JavaScript first appeared 20 years ago. Crazy!

A ResultSetClosedException could be thrown for two reasons.

1.) You have opened another connection to the database without closing all other connections.

2.) Your ResultSet may be returning no values. So when you try to access data from the ResultSet java will throw a ResultSetClosedException.

Since I had to compile some source with 7 compatibility, because of some legacy system and ran into the same problem. I found out that in the gradle configuration there where two options set to java 8

sourceCompatibility = 1.8
targetCompatibility = 1.8

switching these to 1.7 solved the problem for me, keeping JAVA_HOME pointing to the installed JDK-7

sourceCompatibility = 1.7
targetCompatibility = 1.7

Ignore the chrome warning. There is no standard MIME type for OTF fonts.

font/opentype may silence the warning, but that doesn't make it the "right" thing to do.

Arguably, you're better off making one up, e.g. with "application/x-opentype" because at least "application" is a registered content type, while "font" is not.

Update: OTF remains a problem, but WOFF grew an IANA MIME type of application/font-woff in January 2013.

Update 2: OTF has grown a MIME type: application/font-sfnt In March 2013. This type also applies to .ttf

If we just do x.append(y), y gets referenced into x such that any changes made to y will affect appended x as well. So if we need to insert only elements, we should do following:

x = [1,2,3] y = [4,5,6] x.append(y[:])

I'm not sure that I understand what you mean by "rights of ownership".

If User B owns a stored procedure, User B can grant User A permission to run the stored procedure

GRANT EXECUTE ON b.procedure_name TO a

User A would then call the procedure using the fully qualified name, i.e.

BEGIN
  b.procedure_name( <<list of parameters>> );
END;

Alternately, User A can create a synonym in order to avoid having to use the fully qualified procedure name.

CREATE SYNONYM procedure_name FOR b.procedure_name;

BEGIN
  procedure_name( <<list of parameters>> );
END;

As of Python 3.4, subtests have been introduced to unittest for this purpose. See the documentation for details. TestCase.subTest is a context manager which allows one to isolate asserts in a test so that a failure will be reported with parameter information, but it does not stop the test execution. Here's the example from the documentation:

class NumbersTest(unittest.TestCase):

def test_even(self):
    """
    Test that numbers between 0 and 5 are all even.
    """
    for i in range(0, 6):
        with self.subTest(i=i):
            self.assertEqual(i % 2, 0)

The output of a test run would be:

======================================================================
FAIL: test_even (__main__.NumbersTest) (i=1)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "subtests.py", line 32, in test_even
    self.assertEqual(i % 2, 0)
AssertionError: 1 != 0

======================================================================
FAIL: test_even (__main__.NumbersTest) (i=3)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "subtests.py", line 32, in test_even
    self.assertEqual(i % 2, 0)
AssertionError: 1 != 0

======================================================================
FAIL: test_even (__main__.NumbersTest) (i=5)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "subtests.py", line 32, in test_even
    self.assertEqual(i % 2, 0)
AssertionError: 1 != 0

This is also part of unittest2, so it is available for earlier versions of Python.

From Version 4.0.0 on RegionUtil-methods have a new signature. For example:

RegionUtil.setBorderBottom(BorderStyle.DOUBLE,
            CellRangeAddress.valueOf("A1:B7"), sheet);

if you're using NSNotificationCenter for updating your view, don't forget to send it from the main thread by calling dispatch_async:

dispatch_async(dispatch_get_main_queue(),^{
    [[NSNotificationCenter defaultCenter] postNotificationName:@"my_notification" object:nil];
});

No, you can't use a non-standard size or dimension, as it'd wreak havoc on peoples' browsers wherever the icons are displayed. You could make it 12x16 (with four pixels of white/transparent padding on the 12 pixel side) to preserve your aspect ratio, but you can't go bigger (well, you can, but the browser'll shrink it).

You might want to check your CSS. In the example here: https://css-tricks.com/the-checkbox-hack/ there's position: absolute; top: -9999px;. This is particularly goofy on Chrome, as onclick="whatever" still jumps to the absolute position of the clicked element.

Removing position: absolute; top: -9999px;, for display: none; might help.

I tried use [disabled]="!editmode" but it not work in my case.

This is my solution [disabled]="!editmode ? 'disabled': null" , I share for whom concern.

<button [disabled]="!editmode ? 'disabled': null" 
    (click)='loadChart()'>
            <div class="btn-primary">Load Chart</div>
    </button>

You mean you want to add a new row and only put data in a certain column? Try the following:

var row = dataTable.NewRow();
row[myColumn].Value = "my new value";
dataTable.Add(row);

As it is a data table, though, there will always be data of some kind in every column. It just might be DBNull.Value instead of whatever data type you imagine it would be.

You can use OpenLayers (js API for maps).

There's an example on their page showing how to embed OSM tiles.

As long as your program die, then without detach or join of the thread, this error will occur. Without detaching and joining the thread, you should give endless loop after creating thread.

int main(){

std::thread t(thread,1);

while(1){}

//t.detach();
return 0;}

It is also interesting that, after sleeping or looping, thread can be detach or join. Also with this way you do not get this error.

Below example also shows that, third thread can not done his job before main die. But this error can not happen also, as long as you detach somewhere in the code. Third thread sleep for 8 seconds but main will die in 5 seconds.

void thread(int n) {std::this_thread::sleep_for (std::chrono::seconds(n));}

int main() {
std::cout << "Start main\n";
std::thread t(thread,1);
std::thread t2(thread,3);
std::thread t3(thread,8);
sleep(5);

t.detach();
t2.detach();
t3.detach();
return 0;}

If s is your string than you could do it this way:

Mid(s, index, 1)

Edit based on comment below question.

It seems that you need a bit different approach which should be easier. Try in this way:

Dim character As String 'Integer if for numbers
's = ActiveDocument.Content.Text - we don't need it
character = Activedocument.Characters(index)

Try this:

   import * as moment from 'moment';

     ngOnInit() {
     this.date = moment().format("YYYY Do MMM");
                }

You need single quotes around the view name

{% url 'viewname' %}

instead of

{% url viewname %}

I'm pretty sure GSON serializes/deserializes Maps and multiple-nested Maps (i.e. Map<String, Map<String, Object>>) just fine by default. The example provided I believe is nothing more than just a starting point if you need to do something more complex.

Check out the MapTypeAdapterFactory class in the GSON source: http://code.google.com/p/google-gson/source/browse/trunk/gson/src/main/java/com/google/gson/internal/bind/MapTypeAdapterFactory.java

So long as the types of the keys and values can be serialized into JSON strings (and you can create your own serializers/deserializers for these custom objects) you shouldn't have any issues.

You can always use Robomongo. As of v0.8.3 there is a tool that can do this by right-clicking on the collection and selecting "Copy Collection to Database"

For details, see http://blog.robomongo.org/whats-new-in-robomongo-0-8-3/

This feature was removed in 0.8.5 due to its buggy nature so you will have to use 0.8.3 or 0.8.4 if you want to try it out.

FXCop is a code analyzer... It does much more than find unused code. I used FXCop for a while, and was so lost in its recommendations that I uninstalled it.

I think NDepend looks like a more likely candidate.

mysqli_fetch_assoc() expects parameter 1 to be mysqli_result, boolean given

This means that the first parameter you passed is a boolean (true or false).

The first parameter is $result, and it is false because there is a syntax error in the query.

" ... WHERE PartNumber = $partid';"

You should never directly include a request variable in a SQL query, else the users are able to inject SQL in your queries. (See SQL injection.)

You should escape the variable:

" ... WHERE PartNumber = '" . mysqli_escape_string($conn,$partid) . "';"

Or better, use Prepared Statements.

Based on a link to Apache HTTP Components on this SO thread, I came across the Fluent facade API for HTTP Components. An example there shows how to set up a queue of asynchronous HTTP requests (and get notified of their completion/failure/cancellation). In my case, I didn't need a queue, just one async request at a time.

Here's where I ended up (also using URIBuilder from HTTP Components, example here).

import java.net.URI;
import java.net.URISyntaxException;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;
import java.util.concurrent.Future;
import org.apache.http.client.fluent.Async;
import org.apache.http.client.fluent.Content;
import org.apache.http.client.fluent.Request;
import org.apache.http.client.utils.URIBuilder;
import org.apache.http.concurrent.FutureCallback;

//...

URIBuilder builder = new URIBuilder();
builder.setScheme("http").setHost("myhost.com").setPath("/folder")
    .setParameter("query0", "val0")
    .setParameter("query1", "val1")
    ...;
URI requestURL = null;
try {
    requestURL = builder.build();
} catch (URISyntaxException use) {}

ExecutorService threadpool = Executors.newFixedThreadPool(2);
Async async = Async.newInstance().use(threadpool);
final Request request = Request.Get(requestURL);

Future<Content> future = async.execute(request, new FutureCallback<Content>() {
    public void failed (final Exception e) {
        System.out.println(e.getMessage() +": "+ request);
    }
    public void completed (final Content content) {
        System.out.println("Request completed: "+ request);
        System.out.println("Response:\n"+ content.asString());
    }

    public void cancelled () {}
});

As another respondent notes, the file type can be spoofed (e.g., .exe renamed .pdf), which checking for the MIME type will not prevent (i.e., the .exe will show a MIME of "application/pdf" if renamed as .pdf). I believe a check of the true file type can only be done server side; an easy way to check it using System.IO.BinaryReader is described here:

http://forums.asp.net/post/2680667.aspx

and VB version here:

http://forums.asp.net/post/2681036.aspx

Note that you'll need to know the binary 'codes' for the file type(s) you're checking for, but you can get them by implementing this solution and debugging the code.

Using newInstance

public static MyDialogFragment newInstance(int num) {
    MyDialogFragment f = new MyDialogFragment();

    // Supply num input as an argument.
    Bundle args = new Bundle();
    args.putInt("num", num);
    f.setArguments(args);

    return f;
}

And get the Args like this

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    mNum = getArguments().getInt("num");
    ...
}

See the full example here

A big expectation from hash functions is that their result's uniform randomness survives an operation such as hash(x) % N where N is an arbitrary number (and in many cases, a power of two), one reason being that such operations are used commonly in hash tables for determining slots. Using prime number multipliers when computing the hash decreases the probability that your multiplier and the N share divisors, which would make the result of the operation less uniformly random.

Others have pointed out the nice property that multiplication by 31 can be done by a multiplication and a subtraction. I just want to point out that there is a mathematical term for such primes: Mersenne Prime

All mersenne primes are one less than a power of two so we can write them as:

p = 2^n - 1

Multiplying x by p:

x * p = x * (2^n - 1) = x * 2^n - x = (x << n) - x

Shifts (SAL/SHL) and subtractions (SUB) are generally faster than multiplications (MUL) on many machines. See instruction tables from Agner Fog

That's why GCC seems to optimize multiplications by mersenne primes by replacing them with shifts and subs, see here.

However, in my opinion, such a small prime is a bad choice for a hash function. With a relatively good hash function, you would expect to have randomness at the higher bits of the hash. However, with the Java hash function, there is almost no randomness at the higher bits with shorter strings (and still highly questionable randomness at the lower bits). This makes it more difficult to build efficient hash tables. See this nice trick you couldn't do with the Java hash function.

Some answers mention that they believe it is good that 31 fits into a byte. This is actually useless since:

(1) We execute shifts instead of multiplications, so the size of the multiplier does not matter.

(2) As far as I know, there is no specific x86 instruction to multiply an 8 byte value with a 1 byte value so you would have needed to convert "31" to a 8 byte value anyway even if you were multiplying. See here, you multiply entire 64bit registers.

(And 127 is actually the largest mersenne prime that could fit in a byte.)

Does a smaller value increase randomness in the middle-lower bits? Maybe, but it also seems to greatly increase the possible collisions :).

One could list many different issues but they generally boil down to two core principles not being fulfilled well: Confusion and Diffusion

But is it fast? Probably, since it doesn't do much. However, if performance is really the focus here, one character per loop is quite inefficient. Why not do 4 characters at a time (8 bytes) per loop iteration for longer strings, like this? Well, that would be difficult to do with the current definition of hash where you need to multiply every character individually (please tell me if there is a bit hack to solve this :D).

Another solution would be as below where the list is placed under a drop-down button.

  <button class="btn dropdown-toggle btn-primary btn-sm" data-toggle="dropdown"
    >Markets<span class="caret"></span></button>

    <ul class="dropdown-menu", style="height:40%; overflow:hidden; overflow-y:scroll;">
      {{ form.markets }}
    </ul>

To build further upon the ajax part which you may or may not use (from the comments)

a simple way to load another page and replace it with your current one is:

<script>
    $(document).ready( function() {
        $.ajax({
            type: 'get',
            url: 'http://pageToLoad.from',
            success: function(response) {
                // response = data which has been received and passed on to the 'success' function.
                $('body').html(response);
            }
        });
    });
<script>

According to https://docs.docker.com/engine/reference/builder/#run the default [Linux] shell for RUN is /bin/sh -c. You appear to be expecting bashisms, so you should use the "exec form" of RUN to specify your shell.

RUN ["/bin/bash", "-c", "source /usr/local/bin/virtualenvwrapper.sh"]

Otherwise, using the "shell form" of RUN and specifying a different shell results in nested shells.

# don't do this...
RUN /bin/bash -c "source /usr/local/bin/virtualenvwrapper.sh"
# because it is the same as this...
RUN ["/bin/sh", "-c", "/bin/bash" "-c" "source /usr/local/bin/virtualenvwrapper.sh"]

If you have more than 1 command that needs a different shell, you should read https://docs.docker.com/engine/reference/builder/#shell and change your default shell by placing this before your RUN commands:

SHELL ["/bin/bash", "-c"]

Finally, if you have placed anything in the root user's .bashrc file that you need, you can add the -l flag to the SHELL or RUN command to make it a login shell and ensure that it gets sourced.

Note: I have intentionally ignored the fact that it is pointless to source a script as the only command in a RUN.

In Swift 4.2 and Xcode 10

Method 1 :

SIMPLE ALERT

let alert = UIAlertController(title: "Your title", message: "Your message", preferredStyle: .alert)
    
     let ok = UIAlertAction(title: "OK", style: .default, handler: { action in
     })
     alert.addAction(ok)
     let cancel = UIAlertAction(title: "Cancel", style: .default, handler: { action in
     })
     alert.addAction(cancel)
     DispatchQueue.main.async(execute: {
        self.present(alert, animated: true)
})

Method 2 :

ALERT WITH SHARED CLASS

If you want Shared class style(Write once use every where)

import UIKit
class SharedClass: NSObject {//This is shared class
static let sharedInstance = SharedClass()

    //Show alert
    func alert(view: UIViewController, title: String, message: String) {
        let alert = UIAlertController(title: title, message: message, preferredStyle: .alert)
        let defaultAction = UIAlertAction(title: "OK", style: .default, handler: { action in
        })
        alert.addAction(defaultAction)
        DispatchQueue.main.async(execute: {
            view.present(alert, animated: true)
        })
    }

    private override init() {
    }
}

Now call alert like this in every ware

SharedClass.sharedInstance.alert(view: self, title: "Your title here", message: "Your message here")

Method 3 :

PRESENT ALERT TOP OF ALL WINDOWS

If you want to present alert on top of all views, use this code

func alertWindow(title: String, message: String) {
    DispatchQueue.main.async(execute: {
        let alertWindow = UIWindow(frame: UIScreen.main.bounds)
        alertWindow.rootViewController = UIViewController()
        alertWindow.windowLevel = UIWindowLevelAlert + 1
    
        let alert2 = UIAlertController(title: title, message: message, preferredStyle: .alert)
        let defaultAction2 = UIAlertAction(title: "OK", style: .default, handler: { action in
        })
        alert2.addAction(defaultAction2)
    
        alertWindow.makeKeyAndVisible()
    
        alertWindow.rootViewController?.present(alert2, animated: true, completion: nil)
    })
}

Function calling

SharedClass.sharedInstance.alertWindow(title:"This your title", message:"This is your message")

Method 4 :

Alert with Extension

extension  UIViewController {

    func showAlert(withTitle title: String, withMessage message:String) {
        let alert = UIAlertController(title: title, message: message, preferredStyle: .alert)
        let ok = UIAlertAction(title: "OK", style: .default, handler: { action in
        })
        let cancel = UIAlertAction(title: "Cancel", style: .default, handler: { action in
        })
        alert.addAction(ok)
        alert.addAction(cancel)
        DispatchQueue.main.async(execute: {
            self.present(alert, animated: true)
        })
    }
}

Now call like this

//Call showAlert function in your class
@IBAction func onClickAlert(_ sender: UIButton) {
    showAlert(withTitle:"Your Title Here", withMessage: "YourCustomMessageHere")
}

Method 5 :

ALERT WITH TEXTFIELDS

If you want to add textfields to alert.

//Global variables
var name:String?
var login:String?

//Call this function like this:  alertWithTF() 
//Add textfields to alert 
func alertWithTF() {
    
    let alert = UIAlertController(title: "Login", message: "Enter username&password", preferredStyle: .alert)
    // Login button
    let loginAction = UIAlertAction(title: "Login", style: .default, handler: { (action) -> Void in
        // Get TextFields text
        let usernameTxt = alert.textFields![0]
        let passwordTxt = alert.textFields![1]
        //Asign textfileds text to our global varibles
        self.name = usernameTxt.text
        self.login = passwordTxt.text
        
        print("USERNAME: \(self.name!)\nPASSWORD: \(self.login!)")
    })
    
    // Cancel button
    let cancel = UIAlertAction(title: "Cancel", style: .destructive, handler: { (action) -> Void in })
    
    //1 textField for username
    alert.addTextField { (textField: UITextField) in
        textField.placeholder = "Enter username"
        //If required mention keyboard type, delegates, text sixe and font etc...
        //EX:
        textField.keyboardType = .default
    }
    
    //2nd textField for password
    alert.addTextField { (textField: UITextField) in
        textField.placeholder = "Enter password"
        textField.isSecureTextEntry = true
    }
    
    // Add actions
    alert.addAction(loginAction)
    alert.addAction(cancel)
    self.present(alert, animated: true, completion: nil)
    
}

Method 6:

Alert in SharedClass with Extension

//This is your shared class
import UIKit

 class SharedClass: NSObject {

 static let sharedInstance = SharedClass()

 //Here write your code....

 private override init() {
 }
}

//Alert function in shared class
extension UIViewController {
    func showAlert(title: String, msg: String) {
        DispatchQueue.main.async {
            let alert = UIAlertController(title: title, message: msg, preferredStyle: .alert)
            alert.addAction(UIAlertAction(title: "OK", style: .default, handler: nil))
            self.present(alert, animated: true, completion: nil)
        }
    }
}

Now call directly like this

self.showAlert(title: "Your title here...", msg: "Your message here...")

Method 7:

Alert with out shared class with Extension in separate class for alert.

Create one new Swift class, and import UIKit. Copy and paste below code.

//This is your Swift new class file
import UIKit
import Foundation

extension UIAlertController {
    class func alert(title:String, msg:String, target: UIViewController) {
        let alert = UIAlertController(title: title, message: msg, preferredStyle: UIAlertControllerStyle.alert)
        alert.addAction(UIAlertAction(title: "Ok", style: UIAlertActionStyle.default) {
        (result: UIAlertAction) -> Void in
        })
        target.present(alert, animated: true, completion: nil)
    }
}

Now call alert function like this in all your classes (Single line).

UIAlertController.alert(title:"Title", msg:"Message", target: self)

How is it....

Think of it as enforcing Eager-Loading in a scenario where you sub-items would otherwise be lazy-loading.

The Query EF is sending to the database will yield a larger result at first, but on access no follow-up queries will be made when accessing the included items.

On the other hand, without it, EF would execute separte queries later, when you first access the sub-items.

If you will change the ID then Toggle will not working same problem was with me i just change

<div class="collapse navbar-collapse" id="defaultNavbar1">
    <ul class="nav navbar-nav">

id="defaultNavbar1" then toggle is working

ggID='put_googleID_here'  
ggURL='https://drive.google.com/uc?export=download'  
filename="$(curl -sc /tmp/gcokie "${ggURL}&id=${ggID}" | grep -o '="uc-name.*</span>' | sed 's/.*">//;s/<.a> .*//')"  
getcode="$(awk '/_warning_/ {print $NF}' /tmp/gcokie)"  
curl -Lb /tmp/gcokie "${ggURL}&confirm=${getcode}&id=${ggID}" -o "${filename}"  

How does it work?
Get cookie file and html code with curl.
Pipe html to grep and sed and search for file name.
Get confirm code from cookie file with awk.
Finally download file with cookie enabled, confirm code and filename.

curl -Lb /tmp/gcokie "https://drive.google.com/uc?export=download&confirm=Uq6r&id=0B5IRsLTwEO6CVXFURmpQZ1Jxc0U" -o "SomeBigFile.zip"

If you dont need filename variable curl can guess it
-L Follow redirects
-O Remote-name
-J Remote-header-name

curl -sc /tmp/gcokie "${ggURL}&id=${ggID}" >/dev/null  
getcode="$(awk '/_warning_/ {print $NF}' /tmp/gcokie)"  
curl -LOJb /tmp/gcokie "${ggURL}&confirm=${getcode}&id=${ggID}" 

To extract google file ID from URL you can use:

echo "gURL" | egrep -o '(\w|-){26,}'  
# match more than 26 word characters  

OR

echo "gURL" | sed 's/[^A-Za-z0-9_-]/\n/g' | sed -rn '/.{26}/p'  
# replace non-word characters with new line,   
# print only line with more than 26 word characters 

If I am not mistaken, this is what tells the JVM how much successive calls it will accept before issuing a StackOverflowError. Not something you wish to change generally.
