Programs & Examples On #Filedialog

I had to specify individual commands first and then use the * to bring all in command.

from tkinter import filedialog
from tkinter import *

Simply add alignSelf: "stretch" to your item's stylesheet.

line1: {
    backgroundColor: '#FDD7E4',
    alignSelf: 'stretch',
    textAlign: 'center',
},

This works for me with Python3 on Linux:

import tkinter as tk

# Create Tk window
root = tk.Tk()

# Add icon from GIF file where my GIF is called 'icon.gif' and
# is in the same directory as this .py file
root.tk.call('wm', 'iconphoto', root._w, tk.PhotoImage(file='icon.gif'))

before start make sure of installation:

yum install -y xorg-x11-server-Xorg xorg-x11-xauth xorg-x11-apps

1. start xming or cygwin
2. make connection with X11 forwarding (in putty don't forget to set localhost:0.0 for X display location)
3. edit sshd.cong and restart

     cat /etc/ssh/sshd_config | grep X
                             X11Forwarding yes
                             X11DisplayOffset 10
AddressFamily inet

4. Without the X11 forwarding, you are subjected to the X11 SECURITY and then you must: authorize the remote server to make a connection with the local X Server using a method (for instance, the xhost command) set the display environment variable to redirect the output to the X server of your local computer. In this example: 192.168.2.223 is the IP of the server 192.168.2.2 is the IP of the local computer where the x server is installed. localhost can also be used.

blablaco@blablaco01 ~
$ xhost 192.168.2.223
192.168.2.223 being added to access control list

blablaco@blablaco01 ~
$ ssh -l root 192.168.2.223
[email protected] password:
Last login: Sat May 22 18:59:04 2010 from etcetc
[root@oel5u5 ~]# export DISPLAY=192.168.2.2:0.0
[root@oel5u5 ~]# echo $DISPLAY
192.168.2.2:0.0
[root@oel5u5 ~]# xclock&

Then the xclock application must launch.

Check it on putty or mobaxterm and don't check in remote desktop Manager software. Be careful for user that sudo in.

You can as well do:

git checkout --theirs /path/to/file

to keep the remote file, and:

git checkout --ours /path/to/file

to keep local file.

Then git add them and everything is done.

Edition: Keep in mind that this is for a merge scenario. During a rebase --theirs refers to the branch where you've been working.

Try This:

sqlplus -s ${ORA_CONN_STR} <<EOF >/dev/null

No need to install nodemon globally. Just run this npx nodemon <scriptname.js>. That's it.

It worked for me when HDD with win8.1 crashed and my new HDD has win10. Important to know - Create Legacy folder mentioned in this link. - Remember to rename the StickyNotes.snt to ThresholdNotes.snt. - Restart the app

I got this to work by calling this function in document ready:

$(document).ready(function () {
        $.fancybox({
            'width': '40%',
            'height': '40%',
            'autoScale': true,
            'transitionIn': 'fade',
            'transitionOut': 'fade',
            'type': 'iframe',
            'href': 'http://www.example.com'
        });
});

The representation of pointers is irrelevant to comparing them, since all comparisons in C take place as values not representations. The only way to compare the representation would be something hideous like:

static const char ptr_rep[sizeof ptr] = { 0 };
if (!memcmp(&ptr, ptr_rep, sizeof ptr)) ...

Just use this command to disable it. adb shell am clear-debug-app

The below code generates a random number between 100,000 and 900,000. This code will generate six digit values. I'm using this code to generate a six-digit OTP.

Use import java.util.Random to use this random method.

import java.util.Random;

// Six digits random number generation for OTP
Random rnd = new Random();
long longregisterOTP = 100000 + rnd.nextInt(900000);
System.out.println(longregisterOTP);

After doing some research you have 2 options. Since new maps api with iframe embed does not seem to support disabling of mousewheel.

First would be using old google maps ( https://support.google.com/maps/answer/3045828?hl=en ).

Second would be creating a javascript function to simplify embeding of a map for each comment and using parameters (it's sample code only to point location not show exact solution)

function createMap(containerid, parameters) {
  var mymap = document.getElementById(containerid),
  map_options = {
    zoom: 13,
    scrollwheel: false,
    /* rest of options */
  },
  map = new google.maps.Map(mymap, map_options);

  /* 'rest of code' to take parameters into account */
}

Here is my solution for those who use hook; If you are listing items in your grid and want to remove the selected item, you can use this solution.

var list = data.filter(form => form.id !== selectedRowDataId);
setData(list);

For printing the Name column

df['Name']

.divider-vertical {
height: 50px;
margin: 0 9px;
border-left: 1px solid #F2F2F2;
border-right: 1px solid #FFF;
}

and now you can use it

<ul>
    <li class="divider-vertical"></li>
</ul>

You may want to consider using REPLACE INTO syntax, but be warned, upon duplicate PRIMARY / UNIQUE key, it DELETES the row and INSERTS a new one.

You won't need to re-specify all the fields. However, you should consider the possible performance reduction (depends on your table design).

Caveats:

• If you have AUTO_INCREMENT primary key, it will be given a new one
• Indexes will probably need to be updated

Here are some other approaches you can take.

1. CTE with union:

;WITH cte AS (SELECT a, b, c FROM table1)
SELECT a AS val FROM cte
UNION SELECT b AS val FROM cte
UNION SELECT c AS val FROM cte;

2. CTE with unpivot:

;WITH cte AS (SELECT a, b, c FROM table1)
SELECT DISTINCT val
FROM cte
UNPIVOT (val FOR col IN (a, b, c)) u;

If you are using numpy, you have the argsort() function available:

>>> import numpy
>>> numpy.argsort(myList)
array([0, 1, 2, 4, 3])

http://docs.scipy.org/doc/numpy/reference/generated/numpy.argsort.html

This returns the arguments that would sort the array or list.

1. Show where memory is allocated sudo du -x -h / | sort -h | tail -40
2. Delete from either your /tmp or /home/user_name/.cache folder if these are taking up a lot of memory. You can do this by running sudo rm -R /path/to/folder

Step 2 outlines fairly common folders to delete from (/tmp and /home/user_name/.cache). If you get back other results when running the first command showing you have lots of memory being used elsewhere, I advise being a bit more cautious when deleting from those locations.

# file? will only return true for files
File.file?(filename)

and

# Will also return true for directories - watch out!
File.exist?(filename)

Possibly something has changed in recent TensorFlow builds, because for me, running

sess = tf.Session()
sess.run(tf.local_variables_initializer())

before fitting any models seems to do the trick. Most older examples and comments seem to suggest tf.global_variables_initializer().

And for PHP 5.3, you can use this function, which can be embedded in a class or used in procedural style:

http://svn.kd2.org/svn/misc/libs/tools/json_readable_encode.php

Try this:

Dim regDate as Date = Date.Now()
Dim strDate as String = regDate.ToString("ddMMMyyyy")

strDate will look like so: 07Feb2012

You need a regular expression like the following to do it properly:

/^[+-]?((\d+(\.\d*)?)|(\.\d+))$/

The same expression with whitespace, using the extended modifier (as supported by Perl):

/^  [+-]? ( (\d+ (\.\d*)?)  |  (\.\d+) ) $/x

or with comments:

/^           # Beginning of string
 [+-]?       # Optional plus or minus character
 (           # Followed by either:
   (           #   Start of first option
     \d+       #   One or more digits
     (\.\d*)?  #   Optionally followed by: one decimal point and zero or more digits
   )           #   End of first option
   |           # or
   (\.\d+)     #   One decimal point followed by one or more digits
 )           # End of grouping of the OR options
 $           # End of string (i.e. no extra characters remaining)
 /x          # Extended modifier (allows whitespace & comments in regular expression)

For example, it will match:

• 123
• 23.45
• 34.
• .45
• -123
• -273.15
• -42.
• -.45
• +516
• +9.8
• +2.
• +.5

And will reject these non-numbers:

• . (single decimal point)
• -. (negative decimal point)
• +. (plus decimal point)
• (empty string)

The simpler solutions can incorrectly reject valid numbers or match these non-numbers.

java.util.Date object can't represent date in custom format instead you've to use SimpleDateFormat.format method that returns string.

String myString=format1.format(date);

Another solution (might not work for all types)

import scala.collection.breakOut
val m:Map[P, T] = c.map(t => (t.getP, t))(breakOut)

this avoids the creation of the intermediary list, more info here: Scala 2.8 breakOut

You can also try this one

Matrix matrix = new Matrix();

matrix.postRotate(90);

Bitmap scaledBitmap = Bitmap.createScaledBitmap(bitmapOrg, width, height, true);

Bitmap rotatedBitmap = Bitmap.createBitmap(scaledBitmap, 0, 0, scaledBitmap.getWidth(), scaledBitmap.getHeight(), matrix, true);

Then you can use the rotated image to set in your imageview through

imageView.setImageBitmap(rotatedBitmap);

I think method reference with equals method can be used. We assume that the object type without a shadow of a doubt has its own comparison method. Plain and simple example is here,

Set<String> set = new HashSet<>();
set.addAll(Arrays.asList("leo","bale","hanks"));

Set<String> set2 = new HashSet<>();
set2.addAll(Arrays.asList("hanks","leo","bale"));

Predicate<Set> pred = set::equals;
boolean result = pred.test(set2);
System.out.println(result);   // true

You can't style the drop down box itself, only the input field. The box is rendered by the operating system.

If you want more control over the look of your input fields, you can always look into JavaScript solutions.

If, however, your intent was to remove the border from the input itself, your selector is wrong. Try this instead:

select#xyz {
    border: none;
}

I think you need separately date parts like (day, Month, Year)

DateTime today = DateTime.Today;

Will not work for your case. You can get date separately so you don't need variable today to be as a DateTimeType, so lets just give today variable int Type because the day is only int. So today is 10 March 2020 then the result of

int today = DateTime.Today.Day;

int month = DateTime.Today.Month;

int year = DateTime.Today.Year;

MessageBox.Show(today.ToString()+ " - this is day. "+month.ToString()+ " - this is month. " + year.ToString() + " - this is year");

would be "10 - this is day. 3 - this is month. 2020 - this is year"

I think you may be looking for the StringBuilder class. If not, then the generic List class in string form:

List<string> myStringList = new List<string();
myStringList.Add("Test 1");
myStringList.Add("Test 2");

Or, if you need to be absolutely sure that the strings remain in order:

Queue<string> myStringInOriginalOrder = new Queue<string();
myStringInOriginalOrder.Enqueue("Testing...");
myStringInOriginalOrder.Enqueue("1...");
myStringInOriginalOrder.Enqueue("2...");
myStringInOriginalOrder.Enqueue("3...");

Remember, with the List class, the order of the items is an implementation detail and you are not guaranteed that they will stay in the same order you put them in.

The problem, in my case, was that some install at some point defined an environment variable http_proxy on my machine when I had no proxy.

Removing the http_proxy environment variable fixed the problem.

Whenever You merge two branches using command git merge brancha branchb , There are two possibilities:

1. One branch (lets say brancha) can be reached by the other branch (lets say branchb) by following its commits history.In this case git simply fast-forward the head to point to the recent branch (in this case branchb).

   2.But if the two branches have diverged at some older point then git creates a new snapshot and add a new commit that points to it. So in case there is no conflict between the branches you are merging, git smoothly creates a new commit.

Run git log to see the commit after you have merged two non-conflicting branches.

Now coming back to the interesting case when there are merge conflicts between the merging branches. I quote this from the page https://git-scm.com/book/en/v2/Git-Branching-Basic-Branching-and-Merging

Git hasn’t automatically created a new merge commit. It has paused the process while you resolve the conflict. If you want to see which files are unmerged at any point after a merge conflict, you can run git status

So in case there are merge conflicts, you need to resolve the conflict then add the changes you have made to the staging area using git add filename and then commit the changes by using the command git commit which was paused by git because of the conflict.I hope this explains your query. Also do visit the link above for a detailed understanding. In case of any query please comment below , I'll be happy to help.

csvreader.next() Return the next row of the reader’s iterable object as a list, parsed according to the current dialect.

To add a little bit more information that confused me; I had always thought the same result could be achieved like so;

theDate.ToString("yyyy-MM-dd HH:mm:ss")

However, If your Current Culture doesn't use a colon(:) as the hour separator, and instead uses a full-stop(.) it could return as follow:

2009-06-15 13.45.30

Just wanted to add why the answer provided needs to be as it is;

theDate.ToString("yyyy-MM-dd HH':'mm':'ss")

:-)

Javascript is the only viable way to do this client side (that is, CSS won't help you). In jQuery:

$("table td:last").css("border", "none");

I don't know if this solution suits your problem, but it lets you redefine whatever function you want, without having to change code that uses it. Existing calls will use positioned params, while the function implementation may use "named params" (a single hash param).

I thought that you will anyway modify existing function definitions so, why not having a factory function that makes just what you want:

<!DOCTYPE html>

<html>
<head>
<meta charset="UTF-8">
<title></title>
<script type="text/javascript">
var withNamedParams = function(params, lambda) {
    return function() {
        var named = {};
        var max   = arguments.length;

        for (var i=0; i<max; i++) {
            named[params[i]] = arguments[i];
        }

        return lambda(named);
    };
};

var foo = withNamedParams(["a", "b", "c"], function(params) {
    for (var param in params) {
        alert(param + ": " + params[param]);
    }
});

foo(1, 2, 3);
</script>
</head>
<body>

</body>
</html>

Hope it helps.

I needed to exclude an auditing @Aspect @Component from the app context but only for a few test classes. I ended up using @Profile("audit") on the aspect class; including the profile for normal operations but excluding it (don't put it in @ActiveProfiles) on the specific test classes.

You can get the path via fp.name. Example:

>>> f = open('foo/bar.txt')
>>> f.name
'foo/bar.txt'

You might need os.path.basename if you want only the file name:

>>> import os
>>> f = open('foo/bar.txt')
>>> os.path.basename(f.name)
'bar.txt'

With Selenium2Library you can use get_source()

import Selenium2Library
s = Selenium2Library.Selenium2Library()
s.open_browser("localhost:7080", "firefox")
source = s.get_source()

Little addition to Jason's answer:

1. The ToShortDateString() is culture-sensitive.

From MSDN:

The string returned by the ToShortDateString method is culture-sensitive. It reflects the pattern defined by the current culture's DateTimeFormatInfo object. For example, for the en-US culture, the standard short date pattern is "M/d/yyyy"; for the de-DE culture, it is "dd.MM.yyyy"; for the ja-JP culture, it is "yyyy/M/d". The specific format string on a particular computer can also be customized so that it differs from the standard short date format string.

That's mean it's better to use the ToString() method and define format explicitly (as Jason said). Although if this string appeas in UI the ToShortDateString() is a good solution because it returns string which is familiar to a user.

2. If you need just today's date you can use DateTime.Today.

I stumbled upon the same problem and for some reason the --stdin option was not available on the version of passwd I was using (shipped in Ubuntu 14.04).

If any of you happen to experience the same issue, you can work it around as I did, by using the chpasswd command like this:

echo "<user>:<password>" | chpasswd

We had the same error deploying a report to SSRS in our PROD environment. It was found the problem could even be reproduced with a “use ” statement. The solution was to re-sync the user's GUID account reference with the database in question (i.e., using "sp_change_users_login" like you would after restoring a db). A stock (cursor driven) script to re-sync all accounts is attached:

USE <your database>
GO

-------- Reset SQL user account guids ---------------------
DECLARE @UserName nvarchar(255) 
DECLARE orphanuser_cur cursor for 
      SELECT UserName = su.name 
      FROM sysusers su
      JOIN sys.server_principals sp ON sp.name = su.name
      WHERE issqluser = 1 AND
            (su.sid IS NOT NULL AND su.sid <> 0x0) AND
            suser_sname(su.sid) is null 
      ORDER BY su.name 

OPEN orphanuser_cur 
FETCH NEXT FROM orphanuser_cur INTO @UserName 

WHILE (@@fetch_status = 0)
BEGIN 
--PRINT @UserName + ' user name being resynced' 
exec sp_change_users_login 'Update_one', @UserName, @UserName 
FETCH NEXT FROM orphanuser_cur INTO @UserName 
END 

CLOSE orphanuser_cur 
DEALLOCATE orphanuser_cur

How about a solution where you put the actual "data" of the table inside its own div, with overflow: scroll;? Then the browser will automatically create scrollbars for the portion of the "table" you do not want to lock, and you can put the "table header"/first row just above that <div>.

Not sure how that would work with scrolling horizontally though.

As an alternative (if you don't want to use background), you can easily do it by making a view as follows:

<View
    android:layout_width="2dp"
    android:layout_height="match_parent"
    android:background="#000000" />

For having a right border only, place this after the layout (where you want to have the border):

<View
    android:layout_width="2dp"
    android:layout_height="match_parent"
    android:background="#000000" />

For having a left border only, place this before the layout (where you want to have the border):

Worked for me...Hope its of some help....

One additional suggestion to be explicit. It seems best to go from specific to general down the stack of errors to get the desired error to be caught, so the specific ones don't get masked by the general one.

If you have more files in your folder, you can use the below piped command I found in unix stackexchange.

find /some/dir/ -type f -print0 | xargs -0 shuf -e -n 8 -z | xargs -0 cp -vt /target/dir/

Here I wanted to copy the files, but if you want to move files or do something else, just change the last command where I have used cp.

LESS has guard expressions for mixins, not individual attributes.

So you'd create a mixin like this:

.debug(@debug) when (@debug = true) {
    header {
      background-color: yellow;
      #title {
          background-color: orange;
      }
    }

    article {
      background-color: red;
    }
}

And turn it on or off by calling .debug(true); or .debug(false) (or not calling it at all).

First of all, based on your @extend directive, it seems you're not using pure CSS, but a preprocessor such as SASS os Stylus.

Now, when we talk about "order of precedence" in CSS, there is a general rule involved: whatever rules set after other rules (in a top-down fashion) are applied. In your case, just by specifying .smallbox after .smallbox-paysummary you would be able to change the precedence of your rules.

However, if you wanna go a bit further, I suggest this reading: CSS cascade W3C specification. You will find that the precedence of a rule is based on:

1. The current media type;
2. Importance;
3. Origin;
4. Specificity of the selector, and finally our well-known rule:
5. Which one is latter specified.

You might want to use insert method. You can find the documentation for the Tkinter Entry Widget here.

This script inserts a text into Entry. The inserted text can be changed in command parameter of the Button.

from tkinter import *

def set_text(text):
    e.delete(0,END)
    e.insert(0,text)
    return

win = Tk()

e = Entry(win,width=10)
e.pack()

b1 = Button(win,text="animal",command=lambda:set_text("animal"))
b1.pack()

b2 = Button(win,text="plant",command=lambda:set_text("plant"))
b2.pack()

win.mainloop()

Since PyYAML's yaml.load() function parses YAML documents to native Python data structures, you can just access items by key or index. Using the example from the question you linked:

import yaml
with open('tree.yaml', 'r') as f:
    doc = yaml.load(f)

To access branch1 text you would use:

txt = doc["treeroot"]["branch1"]
print txt
"branch1 text"

because, in your YAML document, the value of the branch1 key is under the treeroot key.

Here's another way to do it: as we all know 1x byte = 8x bits and also, a "regular" integer (int32) contains 32 bits (4 bytes). We can use the >> operator to shift bits right (>> operator does not change value.)

int intValue = 566;

byte[] bytes = new byte[4];

bytes[0] = (byte)(intValue >> 24);
bytes[1] = (byte)(intValue >> 16);
bytes[2] = (byte)(intValue >> 8);
bytes[3] = (byte)intValue;

Console.WriteLine("{0} breaks down to : {1} {2} {3} {4}",
    intValue, bytes[0], bytes[1], bytes[2], bytes[3]);

Just echo the javascript out inside the if function

 <form name="testForm" id="testForm"  method="POST"  >
     <input type="submit" name="btn" value="submit" autofocus  onclick="return true;"/>
 </form>
 <?php
    if(isset($_POST['btn'])){
        echo "
            <script type=\"text/javascript\">
            var e = document.getElementById('testForm'); e.action='test.php'; e.submit();
            </script>
        ";
     }
  ?>

#include <iostream>
#include <cstdio>
#include <ctime>

int main() {
    std::clock_t start;
    double duration;

    start = std::clock();

    /* Your algorithm here */

    duration = ( std::clock() - start ) / (double) CLOCKS_PER_SEC;

    std::cout<<"printf: "<< duration <<'\n';
}

In the below investigation as API, I use http://example.com instead of http://myApiUrl/login from your question, because this first one working.

I assume that your page is on http://my-site.local:8088.

The reason why you see different results is that Postman:

• set header Host=example.com (your API)
• NOT set header Origin

This is similar to browsers' way of sending requests when the site and API has the same domain (browsers also set the header item Referer=http://my-site.local:8088, however I don't see it in Postman). When Origin header is not set, usually servers allow such requests by default.

This is the standard way how Postman sends requests. But a browser sends requests differently when your site and API have different domains, and then CORS occurs and the browser automatically:

• sets header Host=example.com (yours as API)
• sets header Origin=http://my-site.local:8088 (your site)

(The header Referer has the same value as Origin). And now in Chrome's Console & Networks tab you will see:

When you have Host != Origin this is CORS, and when the server detects such a request, it usually blocks it by default.

Origin=null is set when you open HTML content from a local directory, and it sends a request. The same situation is when you send a request inside an <iframe>, like in the below snippet (but here the Host header is not set at all) - in general, everywhere the HTML specification says opaque origin, you can translate that to Origin=null. More information about this you can find here.

fetch('http://example.com/api', {method: 'POST'});

Look on chrome-console > network tab

If you do not use a simple CORS request, usually the browser automatically also sends an OPTIONS request before sending the main request - more information is here. The snippet below shows it:

fetch('http://example.com/api', {_x000D_
  method: 'POST',_x000D_
  headers: { 'Content-Type': 'application/json'}_x000D_
});

Look in chrome-console -> network tab to 'api' request._x000D_
This is the OPTIONS request (the server does not allow sending a POST request)

You can change the configuration of your server to allow CORS requests.

Here is an example configuration which turns on CORS on nginx (nginx.conf file) - be very careful with setting always/"$http_origin" for nginx and "*" for Apache - this will unblock CORS from any domain.

location ~ ^/index\.php(/|$) {_x000D_
   ..._x000D_
    add_header 'Access-Control-Allow-Origin' "$http_origin" always;_x000D_
    add_header 'Access-Control-Allow-Credentials' 'true' always;_x000D_
    if ($request_method = OPTIONS) {_x000D_
        add_header 'Access-Control-Allow-Origin' "$http_origin"; # DO NOT remove THIS LINES (doubled with outside 'if' above)_x000D_
        add_header 'Access-Control-Allow-Credentials' 'true';_x000D_
        add_header 'Access-Control-Max-Age' 1728000; # cache preflight value for 20 days_x000D_
        add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';_x000D_
        add_header 'Access-Control-Allow-Headers' 'My-First-Header,My-Second-Header,Authorization,Content-Type,Accept,Origin';_x000D_
        add_header 'Content-Length' 0;_x000D_
        add_header 'Content-Type' 'text/plain charset=UTF-8';_x000D_
        return 204;_x000D_
    }_x000D_
}

Here is an example configuration which turns on CORS on Apache (.htaccess file)

I was also having this issue of "You have mail" coming up every time I started Terminal.

What I discovered is this.

Something I'd installed (not entirely sure what, but possibly a script or something associated with an Alfred Workflow [at a guess]) made a change to the OS X system to start presenting Terminal bash notifications. Prior to that, it appears Wordpress had attempted to use the Local Mail system to send a message. The message bounced, due to it having an invalid Recipient address. The bounced message then ended up in the local system mail inbox. So Terminal (bash) was then notifying me that "You have mail".

You can access the mail by simply using the command

mail

This launches you into Mail, and it will right away show you a list of messages that are stored there. If you want to see the content of the first message, use

t

This will show you the content of the first message, in full. You'll need to scroll down through the message to view it all, by hitting the down-arrow key.

If you want to jump to the end of the message, use the

spacebar

If you want to abort viewing the message, use

q 

To view the next message in the queue use

n

... assuming there's more than one message.

NOTE: You need to use these commands at the mail ? command prompt. They won't work whilst you are in the process of viewing a message. Hitting n whilst viewing a message will just cause an error message related to regular expressions. So, if in the midst of viewing a message, hit q to quit from that, or hit spacebar to jump to the end of the message, and then at the ? prompt, hit n.

Viewing the content of the messages in this way may help you identify what attempted to send the message(s).

You can also view a specific message by just inputting its number at the ? prompt. 3, for instance, will show you the content of the third message (if there are that many in there).

Use the d command (at the ? command prompt )

d [message number]

To delete each message when you are done looking at them. For example, d 2 will delete message number 2. Or you can delete a list of messages, such as d 1 2 5 7. Or you can delete a range of messages with (for example), d 3-10. You can find the message numbers in the list of messages mail shows you.

To delete all the messages, from the mail prompt (?) use the command d *.

As per a comment on this post, you will need to use q to quit mail, which also saves any changes.

If you'd like to see the mail all in one output, use this command at the bash prompt (i.e. not from within mail, but from your regular command prompt):

cat /var/mail/<username>

And, if you wish to delete the emails all in one hit, use this command

sudo rm /var/mail/<username>

In my particular case, there were a number of messages. It looks like the one was a returned message that bounced. It was sent by a local Wordpress installation. It was a notification for when user "Admin" (me) changed its password. Two additional messages where there. Both seemed to be to the same incident.

What I don't know, and can't answer for you either, is WHY I only recently started seeing this mail notification each time I open Terminal. The mails were generated a couple of months ago, and yet I only noticed this "you have mail" appearing in the last few weeks. I suspect it's the result of something a workflow I installed in Alfred, and that workflow using Terminal bash to provide notifications... or something along those lines.

Simply deleting the messages

If you have no interest in determining the source of the messages, and just wish to get rid of them, it may be easier to do so without using the mail command (which can be somewhat fiddly). As pointed out by a few other people, you can use this command instead:

sudo rm /var/mail/YOURUSERNAME

Using the example posted by Brock, I modified it so that it is a category of UIView instead UIViewController and made it recursive so that any subview can (hopefully) find the parent UIViewController.

@interface UIView (FindUIViewController)
- (UIViewController *) firstAvailableUIViewController;
- (id) traverseResponderChainForUIViewController;
@end

@implementation UIView (FindUIViewController)
- (UIViewController *) firstAvailableUIViewController {
    // convenience function for casting and to "mask" the recursive function
    return (UIViewController *)[self traverseResponderChainForUIViewController];
}

- (id) traverseResponderChainForUIViewController {
    id nextResponder = [self nextResponder];
    if ([nextResponder isKindOfClass:[UIViewController class]]) {
        return nextResponder;
    } else if ([nextResponder isKindOfClass:[UIView class]]) {
        return [nextResponder traverseResponderChainForUIViewController];
    } else {
        return nil;
    }
}
@end

To use this code, add it into an new class file (I named mine "UIKitCategories") and remove the class data... copy the @interface into the header, and the @implementation into the .m file. Then in your project, #import "UIKitCategories.h" and use within the UIView code:

// from a UIView subclass... returns nil if UIViewController not available
UIViewController * myController = [self firstAvailableUIViewController];

I have a simple example here to display date and time with Millisecond......

import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;

public class MyClass{

    public static void main(String[]args){
        LocalDateTime myObj = LocalDateTime.now();
        DateTimeFormatter myFormat = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.SSS);
        String forDate = myObj.format(myFormat);
        System.out.println("The Date and Time are: " + forDate);
    }
}

As you can read at http://api.jquery.com/mouseenter/

The mouseenter JavaScript event is proprietary to Internet Explorer. Because of the event's general utility, jQuery simulates this event so that it can be used regardless of browser. This event is sent to an element when the mouse pointer enters the element. Any HTML element can receive this event.

Try putting this in your app/web.config:

<system.net>
    <settings>
        <httpWebRequest useUnsafeHeaderParsing="true" />
    </settings>
</system.net>

If this doesn't work you may also try setting the KeepAlive property to false.

In my experience, if the form is just a "contact" form you don't need special measures. Spam get decently filtered by webmail services (you can track webform requests via server-scripts to see what effectively reach your email, of course I assume you have a good webmail service :D)

Btw I'm trying not to rely on sessions for this (like, counting how many times a button is clicked to prevent overloads).

I don't think that's good, Indeed what I want to achieve is receiving emails from users that do some particular action because those are the users I'm interested in (for example users that looked at "CV" page and used the proper contact form). So if the user do something I want, I start tracking its session and set a cookie (I always set session cookie, but when I don't start a session it is just a fake cookie made to believe the user has a session). If the user do something unwanted I don't bother keeping a session for him so no overload etc.

Also It would be nice for me that advertising services offer some kind of api(maybe that already exists) to see if the user "looked at the ad", it is likely that users looking at ads are real users, but if they are not real well at least you get 1 view anyway so nothing loss. (and trust me, ads controls are more sophisticated than anything you can do alone)

You can use JavaScript functions like replace, and you can wrap the jQuery code in brackets:

var value = ($("#text").val()).replace(".", ":");

Calling child component in parent

<component :is="my_component" ref="my_comp"></component>
<v-btn @click="$refs.my_comp.alertme"></v-btn>

    alertme(){
            alert("alert")
            }
    }

sc queryex type= service state= all | find /i "NATION"

• use /i for case insensitive search
• the white space after type=is deliberate and required

Try to set processData: false in ajax settings like this

$.ajax({
    url : base_url+'index.php',
    type: 'POST',
    dataType: 'json',
    data: data,
    cache : false,
    processData: false
}).done(function(response) {
    alert(response);
});

Using alpha 28, I accomplished programmatically subscribing to event emitters by way of the eventEmitter.toRx().subscribe(..) method. As it is not intuitive, it may perhaps change in a future release.

As cletus said, you should use white-space: nowrap to avoid the line wrapping, and overflow:hidden to hide the overflow. However, in order for a text to be considered overflow, you should set the td/th width, so in case the text requires more than the specified width, it will be considered an overflow, and will be hidden.

Also, if you give a sample web page, responders can provide an updated page with the fix you like.

Wrote this implementation. It allows for missing values, negative values and keeps code consistent. The map is cached as well. Uses an interface and needs Java 8.

Enum

public enum Command implements OrdinalEnum{
    PRINT_FOO(-7),
    PRINT_BAR(6),
    PRINT_BAZ(4);

    private int val;
    private Command(int val){
        this.val = val;
    }

    public int getVal(){
        return val;
    }

    private static Map<Integer, Command> map = OrdinalEnum.getValues(Command.class);
    public static Command from(int i){
        return map.get(i);
    }
}

Interface

public interface OrdinalEnum{
    public int getVal();

    @SuppressWarnings("unchecked")
    static <E extends Enum<E>> Map<Integer, E> getValues(Class<E> clzz){
        Map<Integer, E> m = new HashMap<>();
        for(Enum<E> e : EnumSet.allOf(clzz))
            m.put(((OrdinalEnum)e).getVal(), (E)e);

        return m;
    }
}

This is what I use for lists:

config file content:

[sect]
alist = a
        b
        c

code :

l = config.get('sect', 'alist').split('\n')

it work for strings

in case of numbers

config content:

nlist = 1
        2
        3

code:

nl = config.get('sect', 'alist').split('\n')
l = [int(nl) for x in nl]

thanks.

OPTION 1: Add this line to ~/.zshrc:

export "PATH=$HOME/pear/bin:$PATH"

After that you need to run source ~/.zshrc in order your changes to take affect OR close this window and open a new one

OPTION 2: execute it inside the terminal console to add this path only to the current terminal window session. When you close the window/session, it will be lost.

You can manually set this using Laravel, just remember to add 'created_at' to your $fillable array:

protected $fillable = ['name', 'created_at']; 

The location of the Temporary Internet Files folder depends on your version of Windows and whether or not you are using user profiles.

• If you have Windows Vista, then temporary Internet files are in these locations (note that on your PC they can be on some drive other than C):

  C:\Users[username]\AppData\Local\Microsoft\Windows\Temporary Internet Files\ C:\Users[username]\AppData\Local\Microsoft\Windows\Temporary Internet Files\Low\

  Note that you will have to change the settings of Windows Explorer to show all kinds of files (including the protected system files) in order to access these folders.

• If you have Windows XP or Windows 2000, then temporary Internet files are in this location (note that on your PC they can be on some drive other than C):

  C:\Documents and Settings[username]\Local Settings\Temporary Internet Files\

  If you have only one user account, then replace [username] with Administrator to get the path of the Temporary Internet Files folder.

• If you have Windows Me, Windows 98, Windows NT or Windows 95, then index.dat files are in these locations:

  C:\Windows\Temporary Internet Files\
  C:\Windows\Profiles[username]\Temporary Internet Files\

  Note that on your computer, the Windows directory may not be C:\Windows but some other directory. If you don't have a Profiles directory in your Windows directory, don't worry — this just means that you are not using user profiles.

You can get the diff for a stash with "git show stash@{0}" (or whatever the number of the stash is; see "git stash list"). It's easy to extract the section of the diff for a single file.

So here's what I did to make it dismiss after touching the background or return. I had to add the delegate = self in viewDidLoad and then also the delegate methods later in the .m files.

.h
#import <UIKit/UIKit.h>

@interface ViewController : UIViewController <UITextFieldDelegate>


@property (strong, atomic) UITextField *username;

@end

.m
- (void)viewDidLoad
{
    [super viewDidLoad];

    // Do any additional setup after loading the view, typically from a nib.

    self.view.backgroundColor = [UIColor blueColor];
    self.username = [[UITextField alloc] initWithFrame:CGRectMake(100, 25, 80, 20)];
    self.username.placeholder = @"Enter your username";
    self.username.backgroundColor = [UIColor whiteColor];
    self.username.borderStyle = UITextBorderStyleRoundedRect;
    if (self.username.placeholder != nil) {
        self.username.clearsOnBeginEditing = NO;
    }
    self.username.delegate = self;
    [self.username resignFirstResponder];
    [self.view addSubview:self.username];


}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}


- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField
{
    return YES;
}



- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
    [textField resignFirstResponder];
    return YES;
}

@end

This is the case because the pointer you have for the submodule isn’t what is actually in the submodule directory. To fix this, you must run git submodule update again:

Nested ifs:

if (condition)
{
    // half-massive amount of code here

    if (!breakOutCondition)
    {
        //half-massive amount of code here
    }
}

At the risk of being downvoted -- it's happened to me in the past -- I'll mention that another (unpopular) option would of course be the dreaded goto; a break statement is just a goto in disguise.

And finally, I'll echo the common sentiment that your design could probably be improved so that the massive if statement is not necessary, let alone breaking out of it. At least you should be able to extract a couple of methods, and use a return:

if (condition)
{
    ExtractedMethod1();

    if (breakOutCondition)
        return;

    ExtractedMethod2();
}

You can try multiplying each element in a loop. The short hand for doing that is

ab = [a[i]*b[i] for i in range(len(a))]

protected void TableGrid_RowDataBound(object sender, GridViewRowEventArgs e)
{
   if (e.Row.RowIndex == -1 && e.Row.RowType == DataControlRowType.Header)
   {
      GridViewRow gvRow = new GridViewRow(0, 0, DataControlRowType.DataRow,DataControlRowState.Insert);
      for (int i = 0; i < e.Row.Cells.Count; i++)
      {
         TableCell tCell = new TableCell();
         tCell.Text = "&nbsp;";
         gvRow.Cells.Add(tCell);
         Table tbl = e.Row.Parent as Table;
         tbl.Rows.Add(gvRow);
      }
   }
}

Example:

2.032 MB (2,131,022 bytes)

$u=($mbox.TotalItemSize.value).tostring()

$u=$u.trimend(" bytes)") #yields 2.032 MB (2,131,022

$u=$u.Split("(") #yields `$u[1]` as 2,131,022

$uI=[int]$u[1]

The result is 2131022 in integer form.

You could create a class to represent this

public class Range
{
    private int low;
    private int high;

    public Range(int low, int high){
        this.low = low;
        this.high = high;
    }

    public boolean contains(int number){
        return (number >= low && number <= high);
    }
}

Sample usage:

Range range = new Range(0, 2147483647);

if (range.contains(foo)) {
    //do something
}

On android a far easier way is to use this:

import android.util.Log;
String stackTrace = Log.getStackTraceString(exception); 

I think this and many of the answers around what the spec does or does not say is missing the point of the question.Should they be case sensitive? That's a loaded question really. From a user's point of view, case sensitivity is a pain point, not all know makes a difference. The question of whether URIs should or shouldn't be, depends on the context of the question. For technical flexibility, yes, they should be. For usability, no, they should not be.

NSArray* foo = [@"10/04/2011" componentsSeparatedByString: @"/"];
NSString* firstBit = [foo objectAtIndex: 0];

Update 7/3/2018:

Now that the question has acquired a Swift tag, I should add the Swift way of doing this. It's pretty much as simple:

let substrings = "10/04/2011".split(separator: "/")
let firstBit = substrings[0]

Although note that it gives you an array of Substring. If you need to convert these back to ordinary strings, use map

let strings = "10/04/2011".split(separator: "/").map{ String($0) }
let firstBit = strings[0]

or

let firstBit = String(substrings[0])

Generally, the backtrace is used to get the stack of the current thread, but if there is a necessity to get the stack trace of all the threads, use the following command.

thread apply all bt

Absent of any other information, I'll assume the following XML:

<group>
    <item>
        <id>item 1</id>
        <CategoryName>blue</CategoryName>
    </item>
    <item>
        <id>item 2</id>
        <CategoryName></CategoryName>
    </item>
    <item>
        <id>item 3</id>
    </item>
    ...
</group>

A sample use case would look like:

<xsl:for-each select="/group/item">
    <xsl:if test="CategoryName">
        <!-- will be instantiated for item #1 and item #2 -->
    </xsl:if>
    <xsl:if test="not(CategoryName)">

    </xsl:if>
    <xsl:if test="CategoryName != ''">
        <!-- will be instantiated for item #1 -->
    </xsl:if>
    <xsl:if test="CategoryName = ''">
        <!-- will be instantiated for item #2 -->
    </xsl:if>
</xsl:for-each>

The major difference is time-out, WCF Service has timed-out when there is no response, but web-service does not have this property.

If you can't use JodaTime, you can do the following:

Calendar startCalendar = new GregorianCalendar();
startCalendar.setTime(startDate);
Calendar endCalendar = new GregorianCalendar();
endCalendar.setTime(endDate);

int diffYear = endCalendar.get(Calendar.YEAR) - startCalendar.get(Calendar.YEAR);
int diffMonth = diffYear * 12 + endCalendar.get(Calendar.MONTH) - startCalendar.get(Calendar.MONTH);

Note that if your dates are 2013-01-31 and 2013-02-01, you get a distance of 1 month this way, which may or may not be what you want.

The problem here is that SHA256Managed reads 4096 bytes at a time (inherit from FileStream and override Read(byte[], int, int) to see how much it reads from the filestream), which is too small a buffer for disk IO.

To speed things up (2 minutes for hashing 2 Gb file on my machine with SHA256, 1 minute for MD5) wrap FileStream in BufferedStream and set reasonably-sized buffer size (I tried with ~1 Mb buffer):

// Not sure if BufferedStream should be wrapped in using block
using(var stream = new BufferedStream(File.OpenRead(filePath), 1200000))
{
    // The rest remains the same
}

A modified version of above to make it more dynamic.

Cookies are basically text, so you can store an array by encoding it as a JSON string (see json_encode). Be aware that there is a limit on the length of the string you can store though.

Try this codeplex link, this utility help to localize all stored procedure from sql database.

https://exportmssqlproc.codeplex.com/

You can't use a switch statement for this as the case values cannot be evaluated expressions. For this you have to use an an if/else ...

public static void Output<T>(IEnumerable<T> dataSource) where T : class
{   
    dataSourceName = (typeof(T).Name);
    if(string.Compare(dataSourceName, typeof(CustomerDetails).Name.ToString(), true)==0)
    {
        var t = 123;
    }
    else if (/*case 2 conditional*/)
    {
        //blah
    }
    else
    {
        //default case
        Console.WriteLine("Test");
    }
}

I also took the liberty of tidying up your conditional statement. There is no need to cast to string after calling ToString(). This will always return a string anyway. When comparing strings for equality, bare in mind that using the == operator will result in a case sensitive comparison. Better to use string compare = 0 with the last argument to set case sensitive on/off.

You can use SET ECHO ON in the beginning of your script to achieve that, however, you have to specify your script using @ instead of < (also had to add EXIT at the end):

test.sql

SET ECHO ON

SELECT COUNT(1) FROM dual;

SELECT COUNT(1) FROM (SELECT 1 FROM dual UNION SELECT 2 FROM dual);

EXIT

terminal

sqlplus hr/oracle@orcl @/tmp/test.sql > /tmp/test.log

test.log

SQL> 
SQL> SELECT COUNT(1) FROM dual;

  COUNT(1)
----------
     1

SQL> 
SQL> SELECT COUNT(1) FROM (SELECT 1 FROM dual UNION SELECT 2 FROM dual);

  COUNT(1)
----------
     2

SQL> 
SQL> EXIT

Here is another strtok() implementation, which has the ability to recognize consecutive delimiters (standard library's strtok() does not have this)

The function is a part of BSD licensed string library, called zString. You are more than welcome to contribute :)

https://github.com/fnoyanisi/zString

char *zstring_strtok(char *str, const char *delim) {
    static char *static_str=0;      /* var to store last address */
    int index=0, strlength=0;       /* integers for indexes */
    int found = 0;                  /* check if delim is found */

    /* delimiter cannot be NULL
    * if no more char left, return NULL as well
    */
    if (delim==0 || (str == 0 && static_str == 0))
        return 0;

    if (str == 0)
        str = static_str;

    /* get length of string */
    while(str[strlength])
        strlength++;

    /* find the first occurance of delim */
    for (index=0;index<strlength;index++)
        if (str[index]==delim[0]) {
            found=1;
            break;
        }

    /* if delim is not contained in str, return str */
    if (!found) {
        static_str = 0;
        return str;
    }

    /* check for consecutive delimiters
    *if first char is delim, return delim
    */
    if (str[0]==delim[0]) {
        static_str = (str + 1);
        return (char *)delim;
    }

    /* terminate the string
    * this assignmetn requires char[], so str has to
    * be char[] rather than *char
    */
    str[index] = '\0';

    /* save the rest of the string */
    if ((str + index + 1)!=0)
        static_str = (str + index + 1);
    else
        static_str = 0;

        return str;
}

As mentioned in previous posts, since strtok(), or the one I implmented above, relies on a static *char variable to preserve the location of last delimiter between consecutive calls, extra care should be taken while dealing with multi-threaded aplications.

Sorry to bring up an old post, but I wanted to provide another answer for anyone that comes across this thread.

I had the same problem. No matter what I did, the image just looked like it was complete black. I tried making multiple consecutive calls to cvQueryFrame and noticed that when I made 5 or more, I could see the image. So I started removing the calls one by one to see where the "breaking point" was. What I ended up finding was that the image got darker and darker as I removed each call. Making just a single call provided an image that was almost completely black, but if I looked very closely, I could make out my image.

I tried 10 consecutive calls to test my theory, and sure enough, I was given a very bright image, considering that I'm in a dimly lit room. Hopefully, this was the same problem you were encountering.

I don't know much about imaging, but it looks like multiple consecutive calls to cvQueryFrame increases the length of exposure for the camera. This definitely fixes the problem, though it doesn't seem like the most elegant solution. I'm going to see if I can find a parameter that will increase the exposure, or perhaps some other parameter that will brighten up my images.

Good luck!

Use rgba!

.alpha60 {
    /* Fallback for web browsers that don't support RGBa */
    background-color: rgb(0, 0, 0);
    /* RGBa with 0.6 opacity */
    background-color: rgba(0, 0, 0, 0.6);
    /* For IE 5.5 - 7*/
    filter:progid:DXImageTransform.Microsoft.gradient(startColorstr=#99000000, endColorstr=#99000000);
    /* For IE 8*/
    -ms-filter: "progid:DXImageTransform.Microsoft.gradient(startColorstr=#99000000, endColorstr=#99000000)";
}

In addition to this, you have to declare background: transparent for IE web browsers, preferably served via conditional comments or similar!

For those of you who want more customization in their splitting function, I wrote a recursive algorithm that splits a given string with a list of characters to split on. I wrote this before I saw the above post. I hope it helps some frustrated programmers.

splitString = function(string, splitters) {
    var list = [string];
    for(var i=0, len=splitters.length; i<len; i++) {
        traverseList(list, splitters[i], 0);
    }
    return flatten(list);
}

traverseList = function(list, splitter, index) {
    if(list[index]) {
        if((list.constructor !== String) && (list[index].constructor === String))
            (list[index] != list[index].split(splitter)) ? list[index] = list[index].split(splitter) : null;
        (list[index].constructor === Array) ? traverseList(list[index], splitter, 0) : null;
        (list.constructor === Array) ? traverseList(list, splitter, index+1) : null;    
    }
}

flatten = function(arr) {
    return arr.reduce(function(acc, val) {
        return acc.concat(val.constructor === Array ? flatten(val) : val);
    },[]);
}

var stringToSplit = "people and_other/things";
var splitList = [" ", "_", "/"];
splitString(stringToSplit, splitList);

Example above returns: ["people", "and", "other", "things"]

Note: flatten function was taken from Rosetta Code

EDIT: It seems I was wrong about the performance on the code example. The best performer is whichever snippet runs second in the posted case. This demonstrates what I was trying to explain, and the time differences are not as dramatic:

----------------------------------
--  Monitor time differences
----------------------------------
CREATE CLUSTERED INDEX dtIDX ON #ArbDates (MyDate)
DECLARE @Stopwatch DATETIME 
SET @Stopwatch = GETDATE()
    -- SARGABLE
    SELECT *
    FROM #ArbDates
    WHERE MyDate > DATEADD(DAY, -364, '2010-01-01')


PRINT DATEDIFF(MS, @Stopwatch, GETDATE())
SET @Stopwatch = GETDATE()
    -- NOT SARGABLE
    SELECT *
    FROM #ArbDates
    WHERE DATEDIFF(DAY, MyDate, '2010-01-01') < 365
PRINT DATEDIFF(MS, @Stopwatch, GETDATE())

Excuse me for posting late and my crudely commented example, but I think it important to mention SARG.

SELECT I.Fee
FROM Item I
WHERE  I.DateCreated > DATEADD(DAY, -364, GETDATE())

Although the temp table in the code below has no index, the performance is still enhanced by the fact that a comparison is done between an expression and a value in the table and not an expression that modifies the value in the table and a constant. Hope this is found to be useful.

GO

IF OBJECT_ID('tempdb.dbo.#ArbDates') IS NOT NULL DROP TABLE #ArbDates
DECLARE @Stopwatch DATETIME

Add a View:

1. Right-Click View Folder
2. Click Add -> View
3. Click Create a strongly-typed view
4. Select your User class
5. Select List as the Scaffold template

Add a controller and action method to call the view:

public ActionResult Index()
{
    var users = DataContext.GetUsers();
    return View(users);
}

If the cookie is generated from script, then you can send the cookie manually along with the cookie from the file(using cookie-file option). For example:

# sending manually set cookie
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Cookie: test=cookie"));

# sending cookies from file
curl_setopt($ch, CURLOPT_COOKIEFILE, $ckfile);

In this case curl will send your defined cookie along with the cookies from the file.

If the cookie is generated through javascrript, then you have to trace it out how its generated and then you can send it using the above method(through http-header).

The utma utmc, utmz are seen when cookies are sent from Mozilla. You shouldn't bet worry about these things anymore.

Finally, the way you are doing is alright. Just make sure you are using absolute path for the file names(i.e. /var/dir/cookie.txt) instead of relative one.

Always enable the verbose mode when working with curl. It will help you a lot on tracing the requests. Also it will save lot of your times.

curl_setopt($ch, CURLOPT_VERBOSE, true);

You can make your own animations. For example create xml file in res/anim like this

<?xml version="1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android"
     android:interpolator="@android:anim/linear_interpolator">
    <translate
            android:fromXDelta="100%p"
            android:toXDelta="0"
            android:startOffset="0"
            android:duration="500"
            /> </set>

Then override animations in selected activity:

   overridePendingTransition(R.anim.animationIN, R.anim.animationOUT);

<p>31<sup>st</sup> March 2015</p>

You can use

1<sup>st</sup> 2<sup>nd</sup> 3<sup>rd</sup> 4<sup>th</sup>

for positioning the suffix

give your boxes the class foo (or whatever) and add the css

.foo{
    float: left;
}

Yes, you can script using the reg command. Example:

reg add HKCU\Software\SomeProduct
reg add HKCU\Software\SomeProduct /v Version /t REG_SZ /d v2.4.6

This would create key HKEY_CURRENT_USER\Software\SomeProduct, and add a String value "v2.4.6" named "Version" to that key.

reg /? has the details.

To avoid confusion, paraphrasing both question and answer. I am assuming that user who posted this question wanted to save dictionary type object in JSON file format but when the user used json.dump, this method dumped all its content in one line. Instead, he wanted to record each dictionary entry on a new line. To achieve this use:

with g as outfile:
  json.dump(hostDict, outfile,indent=2)

Using indent = 2 helped me to dump each dictionary entry on a new line. Thank you @agf. Rewriting this answer to avoid confusion.

use return before calling the function, while you click the submit button, two events(form posting as you used submit button and function call for onclick) will happen, to prevent form posting you have to return false, you have did it, also you have to specify the return i.e, to expect a value from the function,

this is a code:

input type="submit" name="continue" value="submit" onClick="**return** checkform();"

For menu bars:

def quit():
    root.destroy()

menubar = Menu(root)
filemenu = Menu(menubar, tearoff=0)

filemenu.add_separator()

filemenu.add_command(label="Exit", command=quit)
menubar.add_cascade(label="menubarname", menu=filemenu)
root.config(menu=menubar)
root.mainloop()

Use the jets3t library. Its a lot more easier and robust than the AWS sdk. Using this library you can call, s3service.getObjectDetails(). This will check and retrieve only the details of the object (not the contents) of the object. It will throw a 404 if the object is missing. So you can catch that exception and deal with it in your app.

But in order for this to work, you will need to have ListBucket access for the user on that bucket. Just GetObject access will not work. The reason being, Amazon will prevent you from checking for the presence of the key if you dont have ListBucket access. Just knowing whether a key is present or not, will also suffice for malicious users in some cases. Hence unless they have ListBucket access they will not be able to do so.

You can use Gson for this.
GSON is a Java library that can be used to convert Java Objects into their JSON representation. It can also be used to convert a JSON string to an equivalent Java object.

Take a look of this Converting JSON to Java

With the global configuration that you have defined for the exec-maven-plugin:

<plugin>
  <groupId>org.codehaus.mojo</groupId>
  <artifactId>exec-maven-plugin</artifactId>
  <version>1.4.0</version>
  <configuration>
    <mainClass>org.dhappy.test.NeoTraverse</mainClass>
  </configuration>
</plugin>

invoking mvn exec:java on the command line will invoke the plugin which is configured to execute the class org.dhappy.test.NeoTraverse.

So, to trigger the plugin from the command line, just run:

mvn exec:java

Now, if you want to execute the exec:java goal as part of your standard build, you'll need to bind the goal to a particular phase of the default lifecycle. To do this, declare the phase to which you want to bind the goal in the execution element:

<plugin>
  <groupId>org.codehaus.mojo</groupId>
  <artifactId>exec-maven-plugin</artifactId>
  <version>1.4</version>
  <executions>
    <execution>
      <id>my-execution</id>
      <phase>package</phase>
      <goals>
        <goal>java</goal>
      </goals>
    </execution>
  </executions>
  <configuration>
    <mainClass>org.dhappy.test.NeoTraverse</mainClass>
  </configuration>
</plugin>

With this example, your class would be executed during the package phase. This is just an example, adapt it to suit your needs. Works also with plugin version 1.1.

If you need to treat empty columns as NULLs, try this:

SELECT CAST(nullif(<column>, '') AS integer);

On the other hand, if you do have NULL values that you need to avoid, try:

SELECT CAST(coalesce(<column>, '0') AS integer);

I do agree, error message would help a lot.

But, setting only that parameters, the authentication don't works.

Are necessary to add to that code the following:

final String authUser = "myuser";
final String authPassword = "secret";

System.setProperty("http.proxyHost", "hostAddress");
System.setProperty("http.proxyPort", "portNumber");
System.setProperty("http.proxyUser", authUser);
System.setProperty("http.proxyPassword", authPassword);

Authenticator.setDefault(
  new Authenticator() {
    public PasswordAuthentication getPasswordAuthentication() {
      return new PasswordAuthentication(authUser, authPassword.toCharArray());
    }
  }
);

As Matt said, the curly braces are for concatenation. The extra curly braces around 16{a[15]} are the replication operator. They are described in the IEEE Standard for Verilog document (Std 1364-2005), section "5.1.14 Concatenations".

{16{a[15]}}

is the same as

{ 
   a[15], a[15], a[15], a[15], a[15], a[15], a[15], a[15],
   a[15], a[15], a[15], a[15], a[15], a[15], a[15], a[15]
}

In bit-blasted form,

assign result = {{16{a[15]}}, {a[15:0]}};

is the same as:

assign result[ 0] = a[ 0];
assign result[ 1] = a[ 1];
assign result[ 2] = a[ 2];
assign result[ 3] = a[ 3];
assign result[ 4] = a[ 4];
assign result[ 5] = a[ 5];
assign result[ 6] = a[ 6];
assign result[ 7] = a[ 7];
assign result[ 8] = a[ 8];
assign result[ 9] = a[ 9];
assign result[10] = a[10];
assign result[11] = a[11];
assign result[12] = a[12];
assign result[13] = a[13];
assign result[14] = a[14];
assign result[15] = a[15];
assign result[16] = a[15];
assign result[17] = a[15];
assign result[18] = a[15];
assign result[19] = a[15];
assign result[20] = a[15];
assign result[21] = a[15];
assign result[22] = a[15];
assign result[23] = a[15];
assign result[24] = a[15];
assign result[25] = a[15];
assign result[26] = a[15];
assign result[27] = a[15];
assign result[28] = a[15];
assign result[29] = a[15];
assign result[30] = a[15];
assign result[31] = a[15];

As an extension to what have been proposed by Nico Coallier (apply to multiple columns) and U10-Forward(using apply style of methods), and summarising it into a one-liner I propose:

df.loc[:,['col1','col2']].transform(lambda x: x.map(lambda x: {1: "A", 2: "B"}.get(x,x))

The .transform() processes each column as a series. Contrary to .apply()which passes the columns aggregated in a DataFrame.

Consequently you can apply the Series method map().

Finally, and I discovered this behaviour thanks to U10, you can use the whole Series in the .get() expression. Unless I have misunderstood its behaviour and it processes sequentially the series instead of bitwisely.
The .get(x,x)accounts for the values you did not mention in your mapping dictionary which would be considered as Nan otherwise by the .map() method

Here's my take on this:

if(object_id(N'[dbo].[fn_Nth_Pos]', N'FN')) is not null
    drop function [dbo].[fn_Nth_Pos];
GO
CREATE FUNCTION [dbo].[fn_Nth_Pos]
(
    @find char, --char to find
    @search varchar(max), --string to process   
    @nth int --occurrence   
)
RETURNS int
AS
BEGIN
    declare @pos int --position of nth occurrence
    --init
    set @pos = 0

    while(@nth > 0)
    begin       
        set @pos = charindex(@find,@search,@pos+1)
        set @nth = @nth - 1
    end 

    return @pos
END
GO

--EXAMPLE
declare @files table(name varchar(max));

insert into @files(name) values('abc_1_2_3_4.gif');
insert into @files(name) values('zzz_12_3_3_45.gif');

        }
    }
}

Then change the class on the carousel from "carousel slide" to "carousel fade". This works in safari, chrome, firefox, and IE 10. It will correctly downgrade in IE 9, however, the nice face effect doesn't happen.

Edit: Since this answer has gotten so popular I've added the following which rewritten as pure CSS instead of the above which was LESS:

.carousel.fade {
  opacity: 1;
}
.carousel.fade .item {
  -moz-transition: opacity ease-in-out .7s;
  -o-transition: opacity ease-in-out .7s;
  -webkit-transition: opacity ease-in-out .7s;
  transition: opacity ease-in-out .7s;
  left: 0 !important;
  opacity: 0;
  top:0;
  position:absolute;
  width: 100%;
  display:block !important;
  z-index:1;
}
.carousel.fade .item:first-child {
  top:auto;
  position:relative;
}
.carousel.fade .item.active {
  opacity: 1;
  -moz-transition: opacity ease-in-out .7s;
  -o-transition: opacity ease-in-out .7s;
  -webkit-transition: opacity ease-in-out .7s;
  transition: opacity ease-in-out .7s;
  z-index:2;
}

The timeout configuration needs to be set at the client level, so the configuration I was setting in the web.config had no effect, the WCF test tool has its own configuration and there is where you need to set the timeout.

An easier way is to use ExecuteTime plugin in jupyter_contrib_nbextensions package.

pip install jupyter_contrib_nbextensions
jupyter contrib nbextension install --user
jupyter nbextension enable execute_time/ExecuteTime

Here's an example that puts the Now() value in column A.

Sub move()
    Dim i As Integer
    Dim sh1 As Worksheet
    Dim sh2 As Worksheet
    Dim nextRow As Long
    Dim copyRange As Range
    Dim destRange As Range

    Application.ScreenUpdating = False

        Set sh1 = ActiveWorkbook.Worksheets("Sheet1")
        Set sh2 = ActiveWorkbook.Worksheets("Sheet2")
        Set copyRange = sh1.Range("A1:A5")

        i = Application.WorksheetFunction.CountA(sh2.Range("B:B")) + 4

        Set destRange = sh2.Range("B" & i)

        destRange.Resize(1, copyRange.Rows.Count).Value = Application.Transpose(copyRange.Value)
        destRange.Offset(0, -1).Value = Format(Now(), "MMM-DD-YYYY")

        copyRange.Clear

    Application.ScreenUpdating = True

End Sub

There are better ways of getting the last row in column B than using a While loop, plenty of examples around here. Some are better than others but depend on what you're doing and what your worksheet structure looks like. I used one here which assumes that column B is ALL empty except the rows/records you're moving. If that's not the case, or if B1:B3 have some values in them, you'd need to modify or use another method. Or you could just use your loop, but I'd search for alternatives :)

Since the introduction of go.mod , I think both local and external package management becomes easier. Using go.mod, it is possible to have go project outside the GOPATH as well.

Import local package:

Create a folder demoproject and run following command to generate go.mod file

go mod init demoproject

I have a project structure like below inside the demoproject directory.

+-- go.mod
+-- src
    +-- main.go
    +-- model
        +-- model.go

For the demo purpose, insert the following code in the model.go file.

package model

type Employee struct {
    Id          int32
    FirstName   string
    LastName    string
    BadgeNumber int32
}

In main.go, I imported Employee model by referencing to "demoproject/src/model"

package main

import (
    "demoproject/src/model"
    "fmt"
)

func main() {
    fmt.Printf("Main Function")

    var employee = model.Employee{
        Id:          1,
        FirstName:   "First name",
        LastName:    "Last Name",
        BadgeNumber: 1000,
    }
    fmt.Printf(employee.FirstName)
}

Import external dependency:

Just run go get command inside the project directory.

For example:

go get -u google.golang.org/grpc

It should include module dependency in the go.mod file

module demoproject

go 1.13

require (
    golang.org/x/net v0.0.0-20200114155413-6afb5195e5aa // indirect
    golang.org/x/sys v0.0.0-20200124204421-9fbb57f87de9 // indirect
    golang.org/x/text v0.3.2 // indirect
    google.golang.org/genproto v0.0.0-20200122232147-0452cf42e150 // indirect
    google.golang.org/grpc v1.26.0 // indirect
)

Integer is only there for the sql standard ie deprecated by Oracle.

You should use Number instead.

Integers get stored as Number anyway by Oracle behind the scenes.

Most commonly when ints are stored for IDs and such they are defined with no params - so in theory you could look at the scale and precision columns of the metadata views to see of no decimal values can be stored - however 99% of the time this will not help.

As was commented above you could look for number(38,0) columns or similar (ie columns with no decimal points allowed) but this will only tell you which columns cannot take decimals, and not what columns were defined so that INTS can be stored.

Suggestion: do a data profile on the number columns. Something like this:

 select max( case when trunc(column_name,0)=column_name then 0 else 1 end ) as has_dec_vals
 from table_name

The most useful thing you can do here is display/i $pc, before using stepi as already suggested in R Samuel Klatchko's answer. This tells gdb to disassemble the current instruction just before printing the prompt each time; then you can just keep hitting Enter to repeat the stepi command.

(See my answer to another question for more detail - the context of that question was different, but the principle is the same.)

I have created a function in PHP language to get browser name, browser version, operating system (windows/linux etc.) along with device type (desktop / mobile / tablet).

function getBrowserInfo(){
    $browserInfo = array('user_agent'=>'','browser'=>'','browser_version'=>'','os_platform'=>'','pattern'=>'', 'device'=>'');

    $u_agent = $_SERVER['HTTP_USER_AGENT']; 
    $bname = 'Unknown';
    $ub = 'Unknown';
    $version = "";
    $platform = 'Unknown';

    $deviceType='Desktop';

This solved my problem of browser detection, I hope, this will also help you. Thank you.

For Dash all previous posts aren't working

The POSIX sh compatible solution is:

result=$(echo "$firstString" | sed "s/Suzi/$secondString/")

This will replace the first occurrence on each line of input. Add a /g flag to replace all occurrences:

result=$(echo "$firstString" | sed "s/Suzi/$secondString/g")

You must always override an abstract function.

Thus:

• Abstract functions - when the inheritor must provide its own implementation
• Virtual - when it is up to the inheritor to decide

Use the SvgImage or the SvgImageConverter extensions, the SvgImageConverter supports binding. See the following link for samples demonstrating both extensions.

https://github.com/ElinamLLC/SharpVectors/tree/master/TutorialSamples/ControlSamplesWpf

You have to use the SelectMany extension method or its equivalent syntax in pure LINQ.

(from model in list
 where model.application == "applicationname"
 from user in model.users
 where user.surname == "surname"
 select new { user, model }).ToList();

Some browser may block popup created by window.open(url, "_blank");. An alternative is to create a link and click on it.

...

  constructor(@Inject(DOCUMENT) private document: Document) {}
...

  openNewWindow(): void {
    const link = this.document.createElement('a');
    link.target = '_blank';
    link.href = 'http://www.your-url.com';
    link.click();
    link.remove();
  }

If you want a popup window rather than a <div />, I would suggest the following approach.

In your parent page, you call a small helper method to show the popup window:

<input type="button" name="choice" onClick="selectValue('sku1')" value="?">

Add the following JS methods:

function selectValue(id)
{
    // open popup window and pass field id
    window.open('sku.php?id=' + encodeURIComponent(id),'popuppage',
      'width=400,toolbar=1,resizable=1,scrollbars=yes,height=400,top=100,left=100');
}

function updateValue(id, value)
{
    // this gets called from the popup window and updates the field with a new value
    document.getElementById(id).value = value;
}

Your sku.php receives the selected field via $_GET['id'] and uses it to construct the parent callback function:

?>
<script type="text/javascript">
function sendValue(value)
{
    var parentId = <?php echo json_encode($_GET['id']); ?>;
    window.opener.updateValue(parentId, value);
    window.close();
}
</script>

For each row in your popup, change code to this:

<td><input type=button value="Select" onClick="sendValue('<?php echo $rows['packcode']; ?>')" /></td>

Following this approach, the popup window doesn't need to know how to update fields in the parent form.

Search for [ ]{2,}. This will find two or more adjacent spaces anywhere within the line. It will also match leading and trailing spaces as well as lines that consist entirely of spaces. If you don't want that, check out Alexander's answer.

Actually, you can leave out the brackets, they are just for clarity (otherwise the space character that is being repeated isn't that well visible :)).

The problem with \s{2,} is that it will also match newlines on Windows files (where newlines are denoted by CRLF or \r\n which is matched by \s{2}.

If you also want to find multiple tabs and spaces, use [ \t]{2,}.

You can do it with the following command:

php artisan make:model post -mcr

Brief :

-m, to create migration

-c to create controller

-r to specify the controller has resource

The existing answers are outdated. This is now doable from the menu:

Window -> Restore Default Layout (shift+f12)

Make sure nothing is currently running, as the Run/Debug window layout will not be reset otherwise.

There are lots of options out there. Many of which are available as downloadable software as well as public websites. I do not think many of them expect to be used as API's unless they explicitly state that.

The one that I found effective was Enju which did not have the character limit that the Marc's Carnagie Mellon link had. Marc also mentioned a VISL scanner in comments, but that requires java in the browser, which is a non-starter for me.

Note that recently, Google has offered a new NLP Machine Learning API that providers amoung other features, a automatic sentence parser. I will likely not update this answer again, especially since the question is closed, but I suspect that the other big ML cloud stacks will soon support the same.

Use \vspace{-\topsep} before \begin{itemize}.

Use \setlength{\parskip}{0pt} \setlength{\itemsep}{0pt plus 1pt} after \begin{itemize}.

And for the space after the list, use \vspace{-\topsep} after \end{itemize}.

\vspace{-\topsep}
\begin{itemize}
  \setlength{\parskip}{0pt}
  \setlength{\itemsep}{0pt plus 1pt}
  \item ...
  \item ...
\end{itemize}
\vspace{-\topsep}

I'll add my experience. Although using the Loaded event can do the job, I think it may be more suitable to override the OnInitialized method. Loaded occurs after the window is first displayed. OnInitialized gives you chance to make any changes, for example, add controls to the window before it is rendered.

 ymin, ymax = axes.get_ylim()

If you are using the plt api directly, you can avoid calls to axes altogether:

def myplotfunction(title, values, errors, plot_file_name):

    # plot errorbars
    indices = range(0, len(values))
    fig = plt.figure()
    plt.errorbar(tuple(indices), tuple(values), tuple(errors), marker='.')

    plt.ylim([-0.5, len(values) - 0.5])
    plt.xlabel('My x-axis title')
    plt.ylabel('My y-axis title')

    # title
    plt.title(title)

    # save as file
    plt.savefig(plot_file_name)

   # close figure
    plt.close(fig)

I'm afraid there's no way to achieve this automatically within the simplejson library.

The scanner and decoder in simplejson are designed to produce unicode text. To do this, the library uses a function called c_scanstring (if it's available, for speed), or py_scanstring if the C version is not available. The scanstring function is called several times by nearly every routine that simplejson has for decoding a structure that might contain text. You'd have to either monkeypatch the scanstring value in simplejson.decoder, or subclass JSONDecoder and provide pretty much your own entire implementation of anything that might contain text.

The reason that simplejson outputs unicode, however, is that the json spec specifically mentions that "A string is a collection of zero or more Unicode characters"... support for unicode is assumed as part of the format itself. Simplejson's scanstring implementation goes so far as to scan and interpret unicode escapes (even error-checking for malformed multi-byte charset representations), so the only way it can reliably return the value to you is as unicode.

If you have an aged library that needs an str, I recommend you either laboriously search the nested data structure after parsing (which I acknowledge is what you explicitly said you wanted to avoid... sorry), or perhaps wrap your libraries in some sort of facade where you can massage the input parameters at a more granular level. The second approach might be more manageable than the first if your data structures are indeed deeply nested.

Why not use margin? you can apply all kinds off margins to an element. Not just the whole margin around it.

You should use css classes since this is referencing more than one element and you can use id's for those that you want to be different specifically

i.e:

<style>
.box { height: 50px; background: #0F0; width: 100%; margin-top: 10px; }
#first { margin-top: 20px; }
#second { background: #00F; }
h1.box { background: #F00; margin-bottom: 50px;  }
</style>

<h1 class="box">Hello World</h1>
<div class="box" id="first"></div>
<div class="box" id="second"></div>?

Just used the Nathan's solution and it works fine. I needed to convert ISO-8859-1 to Unicode:

string isocontent = Encoding.GetEncoding("ISO-8859-1").GetString(fileContent, 0, fileContent.Length);
byte[] isobytes = Encoding.GetEncoding("ISO-8859-1").GetBytes(isocontent);
byte[] ubytes = Encoding.Convert(Encoding.GetEncoding("ISO-8859-1"), Encoding.Unicode, isobytes);
return Encoding.Unicode.GetString(ubytes, 0, ubytes.Length);

var findObjectByLabel = function(obj, label) 
{
  var foundLabel=null;
  if(obj.label === label)
  { 
    return obj; 
  }

for(var i in obj) 
{
    if(Array.isArray(obj[i])==true)
    {
        for(var j=0;j<obj[i].length;j++)
        {
            foundLabel = findObjectByLabel(obj[i], label);
        }
    }
    else if(typeof(obj[i])  == 'object')
    {
        if(obj.hasOwnProperty(i))
        {           
            foundLabel = findObjectByLabel(obj[i], label);     
        }       
    }

    if(foundLabel) 
    { 
        return foundLabel; 
    }

}

return null;
};

var x = findObjectByLabel(cars, "Sedan");
alert(JSON.stringify(x));

This might be useful for someone else: Using this sample html

<div class="ParentDiv">
    <label for="label">labelName</label>
    <input type="button" value="elementToSelect">
</div>
<div class="DontSelect">
    <label for="animal">pig</label>
    <input type="button" value="elementToSelect">
</div>

If for example, I want to select an element in the same section (e.g div) as a label, you can use this

//label[contains(., 'labelName')]/parent::*//input[@value='elementToSelect'] 

This just means, look for a label (it could anything like a, h2) called labelName. Navigate to the parent of that label (i.e. div class="ParentDiv"). Search within the descendants of that parent to find any child element with the value of elementToSelect. With this, it will not select the second elementToSelect with DontSelect div as parent.

The trick is that you can reduce search areas for an element by navigating to the parent first and then searching descendant of that parent for the element you need. Other Syntax like following-sibling::h2 can also be used in some cases. This means the sibling following element h2. This will work for elements at the same level, having the same parent.

valid json string must have double quote.

JSON.parse({"u1":1000,"u2":1100})       // will be ok

no quote cause error

JSON.parse({u1:1000,u2:1100})    
// error Uncaught SyntaxError: Unexpected token u in JSON at position 2

single quote cause error

JSON.parse({'u1':1000,'u2':1100})

>>> cursor.execute("select id from test where id in %s" % str(tuple(sublist)).replace(',)',')'))
>>> a = cursor.fetchall()
>>> a
[(56,), (57,), (58,)]

Other solution for sql string:

cursor.execute("select id from test where id in (%s)" % ('"'+'", "'.join(l)+'"'))

You're trying to assign three separate string literals to a single string variable. A valid string variable would be 'John, Sarah, George'. If you want embedded single quotes between the double quotes, you have to escape them.

Also, your actual SELECT won't work, because SQL databases won't parse the string variable out into individual literal values. You need to use dynamic SQL instead, and then execute that dynamic SQL statement. (Search this site for dynamic SQL, with the database engine you're using as the topic (as in [sqlserver] dynamic SQL), and you should get several examples.)

This is the industry standard:

int is_negative(float num)
{
  char *p = (char*) malloc(20);
  sprintf(p, "%f", num);
  return p[0] == '-';
}

In order to have HSQLDB register itself, you need to access its jdbcDriver class. You can do this the same way as in this example.

Class.forName("org.hsqldb.jdbcDriver");

It triggers static initialization of jdbcDriver class, which is:

static {
    try {
        DriverManager.registerDriver(new jdbcDriver());
    } catch (Exception e) {}
}

If i understood your question correctly you can add multiple columns in a table by using below mentioned query.

Query:

Alter table tablename add (column1 dataype, column2 datatype);

My answer comes quite late because I'm a pretty new developer. This is what you can do:

Location.select(:name, :website, :city).find(row.id)

Btw, this is Rails 4

Another solution that worked:

The data access object that actually throwed this exception is

public List<Foo> findAll() {
    return sessionFactory.getCurrentSession().createQuery("from foo").list();
}

The mistake I did in the above snippet is that I have used the table name foo inside createQuery. Instead, I got to use Foo, the actual class name.

public List<Foo> findAll() {
    return sessionFactory.getCurrentSession().createQuery("from Foo").list();

As per @kexik's suggestion using the UNIX time function as below :

  time_t result = time(NULL);
  NSLog([NSString stringWithFormat:@"The current Unix epoch time is %d",(int)result]);

.As per my experience - don't use timeIntervalSince1970 , it gives epoch timestamp - number of seconds you are behind GMT.

There used to be a bug with [[NSDate date]timeIntervalSince1970] , it used to add/subtract time based on the timezone of the phone but it seems to be resolved now.

With Bootstrap 4 this seems to be working for me:

<div class="row">
  <div class="col"><hr/></div>
  <div class="col-auto">Or</div>
  <div class="col"><hr/></div>
</div>

Sometimes when we do these steps:

 alter table my_table drop constraint my_pk; 
 alter table my_table add constraint my_pk primary key (city_id, buildtime, time);

The last statement fails with

ORA-00955 "name is already used by an existing object"

Oracle usually creates an unique index with the same name my_pk. In such a case you can drop the unique index or rename it based on whether the constraint is still relevant.

You can combine the dropping of primary key constraint and unique index into a single sql statement:

alter table my_table drop constraint my_pk drop index; 

check this: ORA-00955 "name is already used by an existing object"

As of Angular 6+, this is handled slightly differently than in previous versions. As @BeetleJuice mentions in the answer above, paramMap is new interface for getting route params, but the execution is a bit different in more recent versions of Angular. Assuming this is in a component:

private _entityId: number;

constructor(private _route: ActivatedRoute) {
    // ...
}

ngOnInit() {
    // For a static snapshot of the route...
    this._entityId = this._route.snapshot.paramMap.get('id');

    // For subscribing to the observable paramMap...
    this._route.paramMap.pipe(
        switchMap((params: ParamMap) => this._entityId = params.get('id'))
    );

    // Or as an alternative, with slightly different execution...
    this._route.paramMap.subscribe((params: ParamMap) =>  {
        this._entityId = params.get('id');
    });
}

I prefer to use both because then on direct page load I can get the ID param, and also if navigating between related entities the subscription will update properly.

Just add this line

sFileName = "C:\someotherfilelocation"

right before this line

Open sFileName For Output As iFileNum

The idea is to open and write to a different file than the one you read earlier (C:\filelocation).

If you want to get fancy and show a real "Save As" dialog box, you could do this instead:

sFileName = Application.GetSaveAsFilename()

On click of TextField cross button(X) onmousemove() gets fired, we can use this event to call any function.

<input type="search" class="actInput" id="ruleContact" onkeyup="ruleAdvanceSearch()" placeholder="Search..." onmousemove="ruleAdvanceSearch()"/>

You can try viewport units (CSS3):

canvas { 
  height: 100vh; 
  width: 100vw; 
  display: block;
}

You could use p2pkit, or the free solution it was based on: https://github.com/GitGarage. Doesn't work very well, and its a fixer-upper for sure, but its, well, free. Works for small amounts of data transfer right now.

git push --tags production

The at command exists specifically for this purpose (unlike cron which is intended for scheduling recurring tasks).

how to fetch the dropdown values from database and display in jsp:

Dynamically Fetch data from Mysql to (drop down) select option in Jsp. This post illustrates, to fetch the data from the mysql database and display in select option element in Jsp. You should know the following post before going through this post i.e :

How to Connect Mysql database to jsp.

How to create database in MySql and insert data into database. Following database is used, to illustrate ‘Dynamically Fetch data from Mysql to (drop down)

select option in Jsp’ :

id  City
1   London
2   Bangalore
3   Mumbai
4   Paris

Following codes are used to insert the data in the MySql database. Database used is “City” and username = “root” and password is also set as “root”.

Create Database city;
Use city;

Create table new(id int(4), city varchar(30));

insert into new values(1, 'LONDON');
insert into new values(2, 'MUMBAI');
insert into new values(3, 'PARIS');
insert into new values(4, 'BANGLORE');

Here is the code to Dynamically Fetch data from Mysql to (drop down) select option in Jsp:

For the same reasons above, you'll have to convert one of 'a' or 'b' to a double type. Another way of doing it is to use:

double c = (a+0.0)/b;

The numerator is (implicitly) converted to a double because we have added a double to it, namely 0.0.

Three ways you can do this - from the form designer, select the form, and where you normally see the list of properties, just above it there should be a little lightning symbol - this shows you all the events of the form. Find the form load event in the list, and you should be able to pick ProgramViwer_Load from the dropdown.

A second way to do it is programmatically - somewhere (constructor maybe) you'd need to add it, something like: ProgramViwer.Load += new EventHandler(ProgramViwer_Load);

A third way using the designer (probably the quickest) - when you create a new form, double click on the middle of it on it in design mode. It'll create a Form load event for you, hook it in, and take you to the event handler code. Then you can just add your two lines and you're good to go!

Many developers include files by pointing to a remote URL, even if the file is within the local system. For example:

<php include("http://example.com/includes/example_include.php"); ?>

With allow_url_include disabled, this method does not work. Instead, the file must be included with a local path, and there are three methods of doing this:

By using a relative path, such as ../includes/example_include.php. By using an absolute path (also known as relative-from-root), such as /home/username/example.com/includes/example_include.php.

By using the PHP environment variable $_SERVER['DOCUMENT_ROOT'], which returns the absolute path to the web root directory. This is by far the best (and most portable) solution. The following example shows the environment variable in action.

Example Include

<?php include($_SERVER['DOCUMENT_ROOT']."/includes/example_include.php"); ?>

You can try this:

return &Type();

As Andrew Brower says, but adding a trim

ALTER PROCEDURE <Name>
(
    @PartialName VARCHAR(50) = NULL
)

SELECT Name 
    FROM <table>
    WHERE Name LIKE '%' + LTRIM(RTRIM(@PartialName)) + '%'

Queue is an interface that extends Collection in Java. It has all the functions needed to support FIFO architecture.

For concrete implementation you may use LinkedList. LinkedList implements Deque which in turn implements Queue. All of these are a part of java.util package.

For details about method with sample example you can refer FIFO based Queue implementation in Java.

PS: Above link goes to my personal blog that has additional details on this.

&something gives you the address of the std::vector object, not the address of the data it holds. &something.begin() gives you the address of the iterator returned by begin() (as the compiler warns, this is not technically allowed because something.begin() is an rvalue expression, so its address cannot be taken).

Assuming the container has at least one element in it, you need to get the address of the initial element of the container, which you can get via

• &something[0] or &something.front() (the address of the element at index 0), or

• &*something.begin() (the address of the element pointed to by the iterator returned by begin()).

In C++11, a new member function was added to std::vector: data(). This member function returns the address of the initial element in the container, just like &something.front(). The advantage of this member function is that it is okay to call it even if the container is empty.

I am not aware of any solution for the second part of your question. The reason is that it is not clear how to define I changed. Changed when? Just between 2 saves or between commits... Basically - forget it.

I assume you would like to stick to some guideline, but do not touch the rest of the code. But the guideline should be used overall, and not for bites and pieces. So my suggestion is - change all the code to the guideline: it is once-off operation, but make sure that all your developers have the same plugin (AnyEdit) with the same settings for the project.

Just recently I forked a current Github project called "RibbonMenu" and edited it to fit my needs:

https://github.com/jaredsburrows/RibbonMenu

What's the Purpose

• Ease of Access: Allow easy access to a menu that slides in and out
• Ease of Implementation: Update the same screen using minimal amount of code
• Independency: Does not require support libraries such as ActionBarSherlock
• Customization: Easy to change colors and menus

What's New

• Changed the sliding animation to match Facebook and Google+ apps
• Added standard ActionBar (you can chose to use ActionBarSherlock)
• Used menuitem to open the Menu
• Added ability to update ListView on main Activity
• Added 2 ListViews to the Menu, similiar to Facebook and Google+ apps
• Added a AutoCompleteTextView and a Button as well to show examples of implemenation
• Added method to allow users to hit the 'back button' to hide the menu when it is open
• Allows users to interact with background(main ListView) and the menu at the same time unlike the Facebook and Google+ apps!

ActionBar with Menu out

ActionBar with Menu out and search selected

Instead of reinventing the wheel go with envsubst Can be used in almost any scenario, for instance building configuration files from environment variables in docker containers.

If on mac make sure you have homebrew then link it from gettext:

brew install gettext
brew link --force gettext

./template.cfg

# We put env variables into placeholders here
this_variable_1 = ${SOME_VARIABLE_1}
this_variable_2 = ${SOME_VARIABLE_2}

./.env:

SOME_VARIABLE_1=value_1
SOME_VARIABLE_2=value_2

./configure.sh

#!/bin/bash
cat template.cfg | envsubst > whatever.cfg

Now just use it:

# make script executable
chmod +x ./configure.sh
# source your variables
. .env
# export your variables
# In practice you may not have to manually export variables 
# if your solution depends on tools that utilise .env file 
# automatically like pipenv etc. 
export SOME_VARIABLE_1 SOME_VARIABLE_2
# Create your config file
./configure.sh

I ran into a lot of issues when trying to figure this out. Here is my setup,

Dev Env : Windows 10, Java : 1.8.0_25, Spring Boot : 2.0.3.RELEASE, Spring : 5.0.7.RELEASE

What I found is spring is sticking with the concept "Sensible defaults for configuration". What this translates in to is, you have to have all your property files as part of your war file. Once in there, you can then override them using the "--spring.config.additional-location" command line property to point to external property files. But this will NOT WORK if the property files are not part of the original war file.

Demo code: https://github.com/gselvara/spring-boot-property-demo/tree/master

For your list example:

In [1]: x = ['ll','ok','ll']

In [2]: for idx, value in enumerate(x):
   ...:     if value == 'll':
   ...:         print idx, value       
0 ll
2 ll

If you wanted all the items in a list that contained 'll', you could also do that.

In [3]: x = ['Allowed','Hello','World','Hollow']

In [4]: for idx, value in enumerate(x):
   ...:     if 'll' in value:
   ...:         print idx, value
   ...:         
   ...:         
0 Allowed
1 Hello
3 Hollow

1. Pick a random number between [0, x), where x is the number of different symbols. Hopefully the choice is uniformly chosen and not predictable :-)

2. Now choose the symbol representing x.

3. Profit!

I would start reading up Pseudorandomness and then some common Pseudo-random number generators. Of course, your language hopefully already has a suitable "random" function :-)

Use GSONBuilder with setPrettyPrinting and disableHtml for nice output.

String json = new GsonBuilder().setPrettyPrinting().disableHtmlEscaping().
                            create().toJson(outputList  );
                    fileOut.println(json);

Original code by @tavnab.

You can do it with something like this, so if no arguments are specified it will continue anyway:

public static void main(String[] args) {
    try {
        String one = args[0];
        String two = args[1];
    }
    catch (ArrayIndexOutOfBoundsException e){
        System.out.println("ArrayIndexOutOfBoundsException caught");
    }
    finally {

    }
}

And then launch the application:

java -jar myapp.jar arg1 arg2

Using a date picker to get date and a time picker I get two variables, this is how I put them together in unixtime format and then pull them out...

let datetime = oDdate+' '+oDtime;
let unixtime = Date.parse(datetime)/1000;
console.log('unixtime:',unixtime);

to prove it:

let milliseconds = unixtime * 1000;
dateObject = new Date(milliseconds);
console.log('dateObject:',dateObject);

enjoy!

Upgrade pip as follows:

curl https://bootstrap.pypa.io/get-pip.py | python

Note: You may need to use sudo python above if not in a virtual environment.

What's happening:

Python.org sites are stopping support for TLS versions 1.0 and 1.1. This means that Mac OS X version 10.12 (Sierra) or older will not be able to use pip unless they upgrade pip as above.

(Note that upgrading pip via pip install --upgrade pip will also not upgrade it correctly. It is a chicken-and-egg issue)

This thread explains it (thanks to this Twitter post):

Mac users who use pip and PyPI:

If you are running macOS/OS X version 10.12 or older, then you ought to upgrade to the latest pip (9.0.3) to connect to the Python Package Index securely:

curl https://bootstrap.pypa.io/get-pip.py | python

and we recommend you do that by April 8th.

Pip 9.0.3 supports TLSv1.2 when running under system Python on macOS < 10.13. Official release notes: https://pip.pypa.io/en/stable/news/

Also, the Python status page:

Completed - The rolling brownouts are finished, and TLSv1.0 and TLSv1.1 have been disabled. Apr 11, 15:37 UTC

Update - The rolling brownouts have been upgraded to a blackout, TLSv1.0 and TLSv1.1 will be rejected with a HTTP 403 at all times. Apr 8, 15:49 UTC

Lastly, to avoid other install errors, make sure you also upgrade setuptools after doing the above:

pip install --upgrade setuptools

To properly escape spaces as well as the rest of the special characters, use System.Uri.EscapeDataString(string stringToEscape).

Run the following command in terminal:

sudo ln -s /usr/share/phpmyadmin /var/www/html/

"build-prod": "node --max_old_space_size=5120 ./node_modules/@angular/cli/bin/ng build --prod --base-href /"

Now, to bundle my code, I use npm run build-prod instead of ng build --requiredFlagsHere

hope this helps!

I have struggled with the matplotlib trimming methods, so I've now just made a function to do this via a bash call to ImageMagick's mogrify command, which works well and gets all extra white space off the figure's edge. This requires that you are using UNIX/Linux, are using the bash shell, and have ImageMagick installed.

Just throw a call to this after your savefig() call.

def autocrop_img(filename):
    '''Call ImageMagick mogrify from bash to autocrop image'''
    import subprocess
    import os

    cwd, img_name = os.path.split(filename)

    bashcmd = 'mogrify -trim %s' % img_name
    process = subprocess.Popen(bashcmd.split(), stdout=subprocess.PIPE, cwd=cwd)

A much better way is to use inline-block, because you don't need to use clear:both at the end of your list anymore.

Try this:

<ul>
    <li>
        <a href="#">some item</a>
    </li>
    <li>
        <a href="#">another item</a>
    </li>
</ul>

CSS:

ul > li{
    display:inline-block;
}

In VBA this is <> (Not equal to) operator.

The result becomes true if expression1 <> expression2

The result becomes false if expression1 = expression2

For better performance you can use

$('div.a.b')

This will look only through the div elements instead of stepping through all the html elements that you have on your page.

Dates in VBA are just floating point numbers, where the integer part represents the date and the fraction part represents the time. So in addition to using the Date function as tlayton says (to get the current date) you can also cast a date value to a integer to get the date-part from an arbitrary date: Int(myDateValue).
