Those things are Compiler- and Platform-specific. Neither the C nor the C++ standard say anything about calling conventions except for extern "C" in C++.

how does a caller know if it should free up the stack ?

The caller knows the calling convention of the function and handles the call accordingly.

At the call site, does the caller know if the function being called is a cdecl or a stdcall function ?

Yes.

How does it work ?

It is part of the function declaration.

How does the caller know if it should free up the stack or not ?

The caller knows the calling conventions and can act accordingly.

Or is it the linkers responsibility ?

No, the calling convention is part of a function's declaration so the compiler knows everything it needs to know.

If a function which is declared as stdcall calls a function(which has a calling convention as cdecl), or the other way round, would this be inappropriate ?

No. Why should it?

In general, can we say that which call will be faster - cdecl or stdcall ?

I don't know. Test it.

var min = dt.AsEnumerable().Min(row => row["AccountLevel"]);
var max = dt.AsEnumerable().Max(row => row["AccountLevel"]);

This is the fastest way I have found, inspired by @divingTobi's answer. All The answers based on xlrd, openpyxl or pandas are slow for me, as they all load the whole file first.

from zipfile import ZipFile
from bs4 import BeautifulSoup  # you also need to install "lxml" for the XML parser

with ZipFile(file) as zipped_file:

soup = BeautifulSoup(summary, "xml")
sheets = [sheet.get("name") for sheet in soup.find_all("sheet")]

Replacing all zeroes to NA:

df[df == 0] <- NA

Explanation

1. It is not NULL what you should want to replace zeroes with. As it says in ?'NULL',

NULL represents the null object in R

which is unique and, I guess, can be seen as the most uninformative and empty object.¹ Then it becomes not so surprising that

data.frame(x = c(1, NULL, 2))
#   x
# 1 1
# 2 2

That is, R does not reserve any space for this null object.² Meanwhile, looking at ?'NA' we see that

NA is a logical constant of length 1 which contains a missing value indicator. NA can be coerced to any other vector type except raw.

Importantly, NA is of length 1 so that R reserves some space for it. E.g.,

data.frame(x = c(1, NA, 2))
#    x
# 1  1
# 2 NA
# 3  2

Also, the data frame structure requires all the columns to have the same number of elements so that there can be no "holes" (i.e., NULL values).

Now you could replace zeroes by NULL in a data frame in the sense of completely removing all the rows containing at least one zero. When using, e.g., var, cov, or cor, that is actually equivalent to first replacing zeroes with NA and setting the value of use as "complete.obs". Typically, however, this is unsatisfactory as it leads to extra information loss.

2. Instead of running some sort of loop, in the solution I use df == 0 vectorization. df == 0 returns (try it) a matrix of the same size as df, with the entries TRUE and FALSE. Further, we are also allowed to pass this matrix to the subsetting [...] (see ?'['). Lastly, while the result of df[df == 0] is perfectly intuitive, it may seem strange that df[df == 0] <- NA gives the desired effect. The assignment operator <- is indeed not always so smart and does not work in this way with some other objects, but it does so with data frames; see ?'<-'.

_{¹ The empty set in the set theory feels somehow related.
² Another similarity with the set theory: the empty set is a subset of every set, but we do not reserve any space for it.}

        Console.WriteLine("Another line.");
        Console.ResetColor();
    }
}

There are two approaches which are not mentioned above, but both of which solve the problem in a way which complies with PEP 8 and allow you to make better use of your space. They are:

msg = (
    'This message is so long, that it requires '
    'more than {x} lines.{sep}'
    'and you may want to add more.').format(
        x=x, sep=2*'\n')
print(msg)

Notice how the parentheses are used to allow us not to add plus signs between pure strings, and spread the result over multiple lines without the need for explicit line continuation '\' (ugly and cluttered). The advantages are same with what is described below, the difference is that you can do it anywhere. Compared to the previous alternative, it is visually better when inspecting code, because it outlines the start and end of msg clearly (compare with msg += one every line, which needs one additional thinking step to deduce that those lines add to the same string - and what if you make a typo, forgetting a + on one random line ?).

Regarding this approach, many times we have to build a string using iterations and checks within the iteration body, so adding its pieces within the function call, as shown later, is not an option.

A close alternative is:

msg = 'This message is so long, that it requires '
msg += 'many lines to write, one reason for that\n'
msg += 'is that it contains numbers, like this '
msg += 'one: ' + str(x) +', which take up more space\n'
msg += 'to insert. Note how newlines are also included '
msg += 'and can be better presented in the code itself.'
print(msg)

Though the first is preferable.

The other approach is like the previous ones, though it starts the message on the line below the print. The reason for this is to gain space on the left, otherwise the print( itself "pushes" you to the right. This consumption of indentation is the inherited by the rest of the lines comprising the message, because according to PEP 8 they must align with the opening parenthesis of print above them. So if your message was already long, this way it's forced to be spread over even more lines.

Contrast:

raise TypeError('aaaaaaaaaaaaaaaa' +
                'aaaaaaaaaaaaaaaa' +
                'aaaaaaaaaaaaaaaa')

with this (suggested here):

raise TypeError(
    'aaaaaaaaaaaaaaaaaaaaaaaa' +
    'aaaaaaaaaaaaaaaaaaaaaaaa')

The line spread was reduced. Of course this last approach does no apply so much to print, because it is a short call. But it does apply to exceptions.

A variation you can have is:

raise TypeError((
    'aaaaaaaaaaaaaaaaaaaaaaaa'
    'aaaaaaaaaaaaaaaaaaaaaaaa'
    'aaaaa {x} aaaaa').format(x=x))

Notice how you don't need to have plus signs between pure strings. Also, the indentation guides the reader's eyes, no stray parentheses hanging below to the left. The replacements are very readable. In particular, such an approach makes writing code that generates code or mathematical formulas a very pleasant task.

The dependencies syntax is located at the Dependency Version Requirement Specification documentation. Here it is is for completeness:

Dependencies' version element define version requirements, used to compute effective dependency version. Version requirements have the following syntax:

• 1.0: "Soft" requirement on 1.0 (just a recommendation, if it matches all other ranges for the dependency)
• [1.0]: "Hard" requirement on 1.0
• (,1.0]: x <= 1.0
• [1.2,1.3]: 1.2 <= x <= 1.3
• [1.0,2.0): 1.0 <= x < 2.0
• [1.5,): x >= 1.5
• (,1.0],[1.2,): x <= 1.0 or x >= 1.2; multiple sets are comma-separated
• (,1.1),(1.1,): this excludes 1.1 (for example if it is known not to work in combination with this library)

In your case, you could do something like <version>[1.2.3,)</version>

import os    
os.path.getsize(fullpathhere) > 0

This works: http://jsfiddle.net/WHKeK/

function validate_creditcardnumber()
{
    var re16digit=/^\d{16}$/
    if (document.myform.CreditCardNumber.value.search(re16digit) == -1)
        alert("Please enter your 16 digit credit card numbers");
    return false;    
}

You have a typo. You call the variable re16digit, but in your search you have re10digit.

From the documentation:

contentType (default: 'application/x-www-form-urlencoded; charset=UTF-8')

Type: String

When sending data to the server, use this content type. Default is "application/x-www-form-urlencoded; charset=UTF-8", which is fine for most cases. If you explicitly pass in a content-type to $.ajax(), then it'll always be sent to the server (even if no data is sent). If no charset is specified, data will be transmitted to the server using the server's default charset; you must decode this appropriately on the server side.

and:

dataType (default: Intelligent Guess (xml, json, script, or html))

Type: String

The type of data that you're expecting back from the server. If none is specified, jQuery will try to infer it based on the MIME type of the response (an XML MIME type will yield XML, in 1.4 JSON will yield a JavaScript object, in 1.4 script will execute the script, and anything else will be returned as a string).

They're essentially the opposite of what you thought they were.

Here is a simple solution that strips HTML tags and decodes HTML entities based on the amazingly fast lxml library:

from lxml import html

def strip_html(s):
    return str(html.fromstring(s).text_content())

strip_html('Ein <a href="">sch&ouml;ner</a> Text.')  # Output: Ein schöner Text.

tl;dr: Generic Pattern Counter

// THIS IS WHAT YOU NEED
const count = (str) => {
  const re = /YOUR_PATTERN_HERE/g
  return ((str || '').match(re) || []).length
}

For those that arrived here looking for a generic way to count the number of occurrences of a regex pattern in a string, and don't want it to fail if there are zero occurrences, this code is what you need. Here's a demonstration:

/*_x000D_
 *  Example_x000D_
 */_x000D_
_x000D_
const count = (str) => {_x000D_
  const re = /[a-z]{3}/g_x000D_
  return ((str || '').match(re) || []).length_x000D_
}_x000D_
_x000D_
const str1 = 'abc, def, ghi'_x000D_
const str2 = 'ABC, DEF, GHI'_x000D_
_x000D_
console.log(`'${str1}' has ${count(str1)} occurrences of pattern '/[a-z]{3}/g'`)_x000D_
console.log(`'${str2}' has ${count(str2)} occurrences of pattern '/[a-z]{3}/g'`)

Original Answer

The problem with your initial code is that you are missing the global identifier:

>>> 'hi there how are you'.match(/\s/g).length;
4

Without the g part of the regex it will only match the first occurrence and stop there.

Also note that your regex will count successive spaces twice:

>>> 'hi  there'.match(/\s/g).length;
2

If that is not desirable, you could do this:

>>> 'hi  there'.match(/\s+/g).length;
1

I'm not sure there's any one-line robust solution, so you might end up rolling your own.

Lockfiles are imperfect, but less so than using 'ps | grep | grep -v' pipelines.

Having said that, you might consider keeping the process control separate from your script - have a start script. Or, at least factor it out to functions held in a separate file, so you might in the caller script have:

. my_script_control.ksh

# Function exits if cannot start due to lockfile or prior running instance.
my_start_me_up lockfile_name;
trap "rm -f $lockfile_name; exit" 0 2 3 15

in each script that needs the control logic. The trap ensures that the lockfile gets removed when the caller exits, so you don't have to code this on each exit point in the script.

Using a separate control script means that you can sanity check for edge cases: remove stale log files, verify that the lockfile is associated correctly with a currently running instance of the script, give an option to kill the running process, and so on. It also means you've got a better chance of using grep on ps output successfully. A ps-grep can be used to verify that a lockfile has a running process associated with it. Perhaps you could name your lockfiles in some way to include information about the process: user, pid, etc., which can be used by a later script invocation to decide whether the process that created the lockfile is still around.

The error is a stack overflow. That should ring a bell on this site, right? It occurs because a call to poruszanie results in another call to poruszanie, incrementing the recursion depth by 1. The second call results in another call to the same function. That happens over and over again, each time incrementing the recursion depth.

Now, the usable resources of a program are limited. Each function call takes a certain amount of space on top of what is called the stack. If the maximum stack height is reached, you get a stack overflow error.

Reserved.objects.filter(client=client_id).order_by('-check_in')

Notice the - before check_in.

Django Documentation

A volatile can be changed from outside the compiled code (for example, a program may map a volatile variable to a memory mapped register.) The compiler won't apply certain optimizations to code that handles a volatile variable - for example, it won't load it into a register without writing it to memory. This is important when dealing with hardware registers.

A single quote is the start and end of a string. A semicolon is the end of a statement. So if they were doing a select like this:

Select *
From Students
Where (Name = '<NameGetsInsertedHere>')

The SQL would become:

Select *
From Students
Where (Name = 'Robert'); DROP TABLE STUDENTS; --')

On some systems, the select would get ran first followed by the drop statement! The message is: DONT EMBED VALUES INTO YOUR SQL. Instead use parameters!

All depends on your visualization of the array. Rows and Columns are properties of visualization (probably in your imagination) of the array, not the array itself.

It's exactly the same as asking is number "5" red or green?

I could draw it red, I could draw it greed right? Color is not an integral property of a number. In the same way representing 2D array as a grid of rows and columns is not necessary for existence of this array.

2D array has just first dimention and second dimention, everything related to visualizing those is purely your flavour.

When I have char array char[80][25], I may like to print it on console rotated so that I have 25 rows of 80 characters that fits the screen without scroll.

I'll try to provide viable example when representing 2D array as rows and columns doesn't make sense at all: Let's say I need an array of 1 000 000 000 integers. My machine has 8GB of RAM, so I have enough memory for this, but if you try executing var a = new int[1000000000], you'll most likely get OutOfMemory exception. That's because of memory fragmentation - there is no consecutive block of memory of this size. Instead you you can create 2D array 10 000 x 100 000 with your values. Logically it is 1D array, so you'd like to draw and imagine it as a single sequence of values, but due to technical implementation it is 2D.

According to the documentation, timestamp is a synonym for rowversion - it's automatically generated and guaranteed¹ to be unique. datetime isn't - it's just a data type which handles dates and times, and can be client-specified on insert etc.

A colleague told me to use scm.branches[0].name and it worked. I wrapped it to a function in my Jenkinsfile:

def getGitBranchName() {
    return scm.branches[0].name
}

From my testing using this CSS:

.expandable{
display: none;
}
.expand:hover+.expandable{
display:inline !important;
}
.expandable:hover{
display:inline !important;
}

And this HTML:

<div class="expand">expand</div>
<div class="expand">expand</div>
<div class="expandable">expandable</div>

, it resulted that it does expand using the second , but does not expand using the first one. So if there is a div between the hover target and the hidden div, then it will not work.

Double quotes are used for strings (i.e., "this is a string") and single quotes are used for a character (i.e., 'a', 'b' or 'c'). Depending on the programming language and context, you can get away with using double quotes for a character but not single quotes for a string.

HTML doesn't care about which one you use. However, if you're writing HTML inside a PHP script, you should stick with double quotes as you will need to escape them (i.e., \"whatever\") to avoid confusing yourself and PHP.

I noticed that the answers here are using: device-width, device-height, min-device-width, min-device-height, max-device-width, max-device-height.

Please refrain from using them since they are deprecated. see MDN for reference. Instead use the regular min-width, max-width and so on. For extra assurance, you can set the min and max to the same px amount. For example:

iPhone X

@media only screen 
    and (width : 375px) 
    and (height : 635px)
    and (orientation : portrait)  
    and (-webkit-device-pixel-ratio : 3) { }

You may also notice that I am using 635px for height. Try it yourself the window height is actually 635px. run iOS simulator for iPhone X and in Safari Web inspector do window.innerHeight. Here are a few useful links on this subject:

You can turn the axes off by following the advice in Veedrac's comment (linking to here) with one small modification.

Rather than using plt.axis('off') you should use ax.axis('off') where ax is a matplotlib.axes object. To do this for your code you simple need to add axarr[0,0].axis('off') and so on for each of your subplots.

The code below shows the result (I've removed the prune_matrix part because I don't have access to that function, in the future please submit fully working code.)

import matplotlib.pyplot as plt
import matplotlib.image as mpimg
import matplotlib.cm as cm

img = mpimg.imread("stewie.jpg")

f, axarr = plt.subplots(2, 2)
axarr[0,0].imshow(img, cmap = cm.Greys_r)
axarr[0,0].set_title("Rank = 512")
axarr[0,0].axis('off')

axarr[0,1].imshow(img, cmap = cm.Greys_r)
axarr[0,1].set_title("Rank = %s" % 128)
axarr[0,1].axis('off')

axarr[1,0].imshow(img, cmap = cm.Greys_r)
axarr[1,0].set_title("Rank = %s" % 32)
axarr[1,0].axis('off')

axarr[1,1].imshow(img, cmap = cm.Greys_r)
axarr[1,1].set_title("Rank = %s" % 16)
axarr[1,1].axis('off')

plt.show()

Note: To turn off only the x or y axis you can use set_visible() e.g.:

axarr[0,0].xaxis.set_visible(False) # Hide only x axis

As the question is asked years ago, and Android is evolved a lot on this URI scheme.
From original URI scheme, to deep link, and now Android App Links.

Android now recommends to use HTTP URLs, not define your own URI scheme. Because Android App Links use HTTP URLs that link to a website domain you own, so no other app can use your links. You can check the comparison of deep link and Android App links from here

Now you can easily add a URI scheme by using Android Studio option: Tools > App Links Assistant. Please refer the detail to Android document: https://developer.android.com/studio/write/app-link-indexing.html

To get body content from javascript ,i have tried the following code:

var frameObj = document.getElementById('id_description_iframe');

var frameContent = frameObj.contentWindow.document.body.innerHTML;

where "id_description_iframe" is your iframe's id. This code is working fine for me.

You need BEGIN ... END to create a block spanning more than one statement. So, if you wanted to do 2 things in one 'leg' of an IF statement, or if you wanted to do more than one thing in the body of a WHILE loop, you'd need to bracket those statements with BEGIN...END.

The GO keyword is not part of SQL. It's only used by Query Analyzer to divide scripts into "batches" that are executed independently.

The best way is to download an installer package: .pkg on mac. Prefer the latest stable version.

Here is the link: Node.js

This package will eventually overwrite the previous version and set environment variables accordingly. Just run the installer and its done within a few clicks.

Adding this here as it doesn't seem to be here.

Aside from the excellent solution of form.append("blob",blob, filename); you can also turn the blob into a File instance:

var blob = new Blob([JSON.stringify([0,1,2])], {type : 'application/json'});
var fileOfBlob = new File([blob], 'aFileName.json');
form.append("upload", fileOfBlob);

This checks if the array is empty

if (!empty($result) {
    // do stuf if array is not empty
} else {
    // do stuf if array is empty
}

This checks if the array is null or not

if (is_null($result) {
   // do stuf if array is null
} else {
   // do stuf if array is not null
}

you can use any one for rails 3.2:

request.original_url
or
request.env["HTTP_REFERER"]
or
request.env['REQUEST_URI']

I think it will work every where

"#{request.protocol}#{request.host}:#{request.port}#{request.fullpath}"

The intend of most of the programmatically generated emails is generally transactional, triggered or alert n nature- which means these are important emails which should never land into spam.

Having said that there are multiple parameters which are been considered before flagging an email as spam. While Quality of email list is the most important parameter to be considered, but I am skipping that here from the discussion because here we are talking about important emails which are sent to either ourself or to known email addresses.

Apart from list quality, the other 3 important parameters are;

1. Sender Reputation
2. Compliance with Email Standards and Authentication (SPF, DKIM, DMARC, rDNS)
3. Email content

Sender Reputation = Reputation of Sending IP address + Reputation of Return Path/Envelope domain + Reputation of From Domain.

There is no straight answer to what is your Sender Reputation. This is because there are multiple authorities like SenderScore, Reputation Authority and so on who maintains the reputation score for your domain. Apart from that ISPs like Gmail, Yahoo, Outlook also maintains the reputation of each domain at their end.

But, you can use free tools like GradeMyEmail to get a 360-degree view of your reputation and potential problems with your email settings or any other compliance-related issue too.

Sometimes, if you're using a new domain for sending an email, then those are also found to land in spam. You should be checking whether your domain is listed on any of the global blocklists or not. Again GradeMyEmail and MultiRBL are useful tools to identify the list of blocklists.

Once you're pretty sure with the sender reputation score, you should check whether your email sending domain complies with all email authentications and standards.

1. SPF
2. DKIM
3. DMARC
4. Reverse DNS

For this, you can again use GradeMyEmail or MXToolbox to know the potential problems with your authentication.

Your SPF, DKIM and DMARC should always PASS to ensure, your emails are complying with the standard email authentications. Here's an example of how these authentications should look like in Gmail:

Similarly, you can use tools like Mail-Tester which scans the complete email content and tells the potential keywords which can trigger spam filters.

The proper way of checking if array key exists is function array_key_exists()

The difference is that when you have $_POST['variable'] = null it means that key exists and was send but value was null

The other option is isset() which which will check if array key exists and if it was set

The last option is to use empty() which will check if array key exists if is set and if value is not considered empty.

Examples:

$arr = [
  'a' => null,
  'b' => '',
  'c' => 1
];

array_key_exists('a', $arr); // true
isset($arr['a']); // false
empty($arr['a']); // true


array_key_exists('b', $arr); // true
isset($arr['b']); // true
empty($arr['b']); // true


array_key_exists('c', $arr); // true
isset($arr['c']); // true
empty($arr['c']); // false

Regarding your question

The proper way to check if value was send is to use array_key_exists() with check of request method

if ($_SERVER['REQUEST_METHOD'] == 'POST' && array_key_exists('fromPerson', $_POST)    
{
   // logic
}

But there are some cases depends on your logic where isset() and empty() can be good as well.

Proper way to fix this issue is to change meta viewport to:

<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=0"/>

Important: do not set minimum-scale! This keeps the page manually zoomable.

SET myParam = IFNULL(myParam, 0);

Explanation: IFNULL(expression_1, expression_2)

The IFNULL function returns expression_1 if expression_1 is not NULL; otherwise it returns expression_2. The IFNULL function returns a string or a numeric based on the context where it is used.

Your css is fine, but I think it's not applying on divs. Just write simple class name and then try. You can check it at Jsfiddle.

.left {
  float: left;
  width: 125px;
  text-align: right;
  margin: 2px 10px;
  display: inline;
}

.right {
  float: left;
  text-align: left;
  margin: 2px 10px;
  display: inline;
}

I fixed this by adding the following into MainApplication.onCreate:

try {
    PackageInfo info = getPackageManager().getPackageInfo(
                           "com.genolingo.genolingo",
                           PackageManager.GET_SIGNATURES);

    for (Signature signature : info.signatures) {
        MessageDigest md = MessageDigest.getInstance("SHA");
        md.update(signature.toByteArray());
        String hash = Base64.encodeToString(md.digest(), Base64.DEFAULT);
        KeyHash.addKeyHash(hash);
    }
}
catch (PackageManager.NameNotFoundException e) {
    Log.e("PackageInfoError:", "NameNotFoundException");
}
catch (NoSuchAlgorithmException e) {
    Log.e("PackageInfoError:", "NoSuchAlgorithmException");
}

I then uploaded this to the Google developer console and then downloaded the derived APK which, for whatever reason, has a totally different key hash.

I then used LogCat to determine the new key hash and added it Facebook as other users have outlined.

you need a tiny bit of Javascript.

<script type="text/javascript">
window.onload = function(){ 
                alert("Hi there");
                }
</script>

This is only slightly different from Adam's answer. The effective difference is that this one alerts when the browser considers the page fully loaded, while Adam's alerts when the browser scans part the <script> tag in the text. The difference is with, for example, images, which may continue loading in parallel for a while.

Javascript Variables

You can start a variable with any letter, $, or _ character. As long as it doesn't start with a number, you can include numbers as well.

Start: [a-z], $, _

Contain: [a-z], [0-9], $, _

jQuery

You can use _ for your library so that it will stand side-by-side with jQuery. However, there is a configuration you can set so that jQuery will not use $. It will instead use jQuery. To do this, simply set:

jQuery.noConflict();

This page explains how to do this.

userInfos.GroupBy(userInfo => userInfo.metric)
        .OrderBy(group => group.Key)
        .Select(group => Tuple.Create(group.Key, group.Count()));

You have to do following steps.

Go to IIS ->
Sites->
Click on Your Web site ->
In Action Click on Edit Permissions ->
Security ->
Click on ADD ->
Advanced ->
Find Now ->
Add all the users in it ->
and grant all permissions to other users ->
click on Ok.

If you do above things properly you can access your web site by using your domain.
Suggestion - Do not add host name to your site it creates problem sometime. So please host your web site using your machines ip address.

The problem is on this line:

oShell.run "cmd.exe /C copy "S:Claims\Sound.wav" "C:\WINDOWS\Media\Sound.wav"

Your first quote next to "S:Claims" ends the string; you need to escape the quotes around your files with a second quote, like this:

oShell.run "cmd.exe /C copy ""S:\Claims\Sound.wav"" ""C:\WINDOWS\Media\Sound.wav"" "

You also have a typo in S:Claims\Sound.wav, should be S:\Claims\Sound.wav.

I also assume the apostrophe before Dim oShell and after Set oShell = Nothing are typos as well.

SELECT * FROM  mysql.general_log  WHERE command_type ='Query' LIMIT total;

Try this:

function MyController($scope) {
    $scope.form = {
        name: 'my name',
        surname: 'surname'
    }

    function track(newValue, oldValue, scope) {
        console.log('changed');
    };

    $scope.$watch('form.name', track);
}

I just found this :

 private static bool TrySetSuppressScriptErrors(WebBrowser webBrowser, bool value)
    {
        FieldInfo field = typeof(WebBrowser).GetField("_axIWebBrowser2", BindingFlags.Instance | BindingFlags.NonPublic);
        if (field != null)
        {
            object axIWebBrowser2 = field.GetValue(webBrowser);
            if (axIWebBrowser2 != null)
            {
                axIWebBrowser2.GetType().InvokeMember("Silent", BindingFlags.SetProperty, null, axIWebBrowser2, new object[] { value });
                return true;
            }
        }

        return false;
    }

usage example to set webBrowser to silent : TrySetSuppressScriptErrors(webBrowser,true)

Usually used for embedding custom data, like pictures or sound data within an XML document.

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

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

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

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

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

A lot of the above work. Just to add. If your textboxes are not directly on the form but are on other container objects like a GroupBox, you will have to get the GroupBox object and then iterate through the GroupBox to access the textboxes contained therein.

foreach(Control t in this.Controls.OfType<GroupBox>())
{
   foreach (Control tt in t.Controls.OfType<TextBox>())
   {
        // do stuff
   }
}

You'd better not transpose the data.frame while the name column is in it - all numeric values will then be turned into strings!

Here's a solution that keeps numbers as numbers:

# first remember the names
n <- df.aree$name

# transpose all but the first column (name)
df.aree <- as.data.frame(t(df.aree[,-1]))
colnames(df.aree) <- n
df.aree$myfactor <- factor(row.names(df.aree))

str(df.aree) # Check the column types

Another Way That worked for me is to Subclass UINavigationBar And leave the drawRect Method empty !!

@IBDesignable class MONavigationBar: UINavigationBar {


// Only override drawRect: if you perform custom drawing.
// An empty implementation adversely affects performance during animation.
override func drawRect(rect: CGRect) {
    // Drawing code
}}

To kill a process by name I use the following

ps aux | grep "search-term" | grep -v grep | tr -s " " | cut -d " " -f 2 | xargs kill -9

The tr -s " " | cut -d " " -f 2 is same as awk '{print $2}'. tr supressess the tab spaces into single space and cut is provided with <SPACE> as the delimiter and the second column is requested. The second column in the ps aux output is the process id.

One way to print your code is to push it to an online version control system like Github or Bitbucket. In your browser, navigate to the file and print it.

Doing it this way, you'll get syntax highlighting and version control.

Pure speculation is that you're using a terminal that attempts to do word-wrapping rather than character-wrapping, and treats B as a word character but # as a non-word character. So when it reaches the end of a line and searches for a place to break the line, it sees a # almost immediately and happily breaks there; whereas with the B, it has to keep searching for longer, and may have more text to wrap (which may be expensive on some terminals, e.g., outputting backspaces, then outputting spaces to overwrite the letters being wrapped).

But that's pure speculation.

Assuming that you have the power to make schema changes the only acceptable answer to this question IMO is to change the base data type to something more appropriate (e.g. date if SQL Server 2008).

Storing dates as mm/dd/yyyy strings is space inefficient, difficult to validate correctly and makes sorting and date calculations needlessly painful.

See ?read.table. Basically, when you use read.table, you specify a number indicating the column:

##Row names in the first column
read.table(filname.txt, row.names=1)

Use the Integer class' static toString() method.

int sdRate=5;
text_Rate.setText(Integer.toString(sdRate));

You can pass new value like this

  setExampleState({...exampleState,  masterField2: {
        fieldOne: "c",
        fieldTwo: {
           fieldTwoOne: "d",
           fieldTwoTwo: "e"
           }
        },
   }})

In answer to your first question, it should be as simple as replacing:

   when(LoggerFactory.getLogger(GoodbyeController.class)).thenReturn(loggerMock);

with

   when(LoggerFactory.getLogger(any(Class.class))).thenReturn(loggerMock);

Regarding your second question (and possibly the puzzling behavior with the first), I think the problem is that logger is static. So,

private static Logger logger = LoggerFactory.getLogger(GoodbyeController.class);

is executed when the class is initialized, not the when the object is instantiated. Sometimes this can be at about the same time, so you'll be OK, but it's hard to guarantee that. So you set up LoggerFactory.getLogger to return your mock, but the logger variable may have already been set with a real Logger object by the time your mocks are set up.

You may be able to set the logger explicitly using something like ReflectionTestUtils (I don't know if that works with static fields) or change it from a static field to an instance field. Either way, you don't need to mock LoggerFactory.getLogger because you'll be directly injecting the mock Logger instance.

I was having this same issue and after much wrangling I decided to try and isolate the problem and simply load the script manager in an empty page which still resulted in this same error. Having isolated the problem I discovered through a comparison of my site's web.config with a brand new (working) test site that changing <compilation debug="true"> to <compilation debug="false"> in the system.web section of my web.config fixes the problem.

I also had to remove the <xhtmlConformance mode="Legacy"/> entry from system.web to make the update panel work properly. Click here for a description of this issue.

Make the (LinearLayout) android:layout_width="match_parent" and the TextView's android:layout_gravity="right"

This would work just fine, set the height to desired pixel

#inner-right{
            height: 100px;
            overflow:auto;
            }

Sven Marnach's answer is pretty much it, but has one generality issue... It will fail if the list being printed doesn't just contain strings.

So, the more general answer to "How to print out a list with elements separated by newlines"...

print '\n'.join([ str(myelement) for myelement in mylist ])

Then again, the print function approach JBernardo points out is superior. If you can, using the print function instead of the print statement is almost always a good idea.

You don't need to add the concat package, you can do this via cssmin like this:

cssmin : {
      options: {
            keepSpecialComments: 0
      },
      minify : {
            expand : true,
            cwd : '/library/css',
            src : ['*.css', '!*.min.css'],
            dest : '/library/css',
            ext : '.min.css'
      },
      combine : {
        files: {
            '/library/css/app.combined.min.css': ['/library/css/main.min.css', '/library/css/font-awesome.min.css']
        }
      }
    }

And for js, use uglify like this:

uglify: {
      my_target: {
        files: {
            '/library/js/app.combined.min.js' : ['/app.js', '/controllers/*.js']
        }
      }
    }

If using Android Studio, do the following (I've copied and modified @Vinayak Bs answer):

1. Select the Project view in the Project sideview (instead of Packages or Android)
2. Create a folder called libs in your project's root folder
3. Copy your JAR files to the libs folder
4. The sideview will be updated and the JAR files will show up in your project
5. Now right click on each JAR file you want to import and then select "Add as Library...", which will include it in your project
6. After that, all you need to do is reference the new classes in your code, eg. import javax.mail.*

I had to check if Git was installed as part of deploying our CI server. My final Bash script was as follows (Ubuntu server):

if ! builtin type -p git &>/dev/null; then
  sudo apt-get -y install git-core
fi

I have used jQuery AJAX to make AJAX requests.

Check the following code:

<html>
<head>
    <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js"></script>
    <script type="text/javascript">
        $(document).ready(function() {
            $('#call').click(function ()
            {
                $.ajax({
                    type: "post",
                    url: "testme", //this is my servlet
                    data: "input=" +$('#ip').val()+"&output="+$('#op').val(),
                    success: function(msg){      
                            $('#output').append(msg);
                    }
                });
            });

        });
    </script>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    <title>JSP Page</title>
</head>
<body>
    input:<input id="ip" type="text" name="" value="" /><br></br>
    output:<input id="op" type="text" name="" value="" /><br></br>
    <input type="button" value="Call Servlet" name="Call Servlet" id="call"/>
    <div id="output"></div>
</body>

The easiest and most intuitive solution for me was to combine the column names using get_level_values. This prevents duplicate column names when you do more than one aggregation on the same column:

level_one = df.columns.get_level_values(0).astype(str)
level_two = df.columns.get_level_values(1).astype(str)
df.columns = level_one + level_two

If you want a separator between columns, you can do this. This will return the same thing as Seiji Armstrong's comment on the accepted answer that only includes underscores for columns with values in both index levels:

level_one = df.columns.get_level_values(0).astype(str)
level_two = df.columns.get_level_values(1).astype(str)
column_separator = ['_' if x != '' else '' for x in level_two]
df.columns = level_one + column_separator + level_two

I know this does the same thing as Andy Hayden's great answer above, but I think it is a bit more intuitive this way and is easier to remember (so I don't have to keep referring to this thread), especially for novice pandas users.

This method is also more extensible in the case where you may have 3 column levels.

level_one = df.columns.get_level_values(0).astype(str)
level_two = df.columns.get_level_values(1).astype(str)
level_three = df.columns.get_level_values(2).astype(str)
df.columns = level_one + level_two + level_three

Peter's post is pretty much spot on, but if you want to learn how to navigate to it yourself here are the instructions:

On the left hand menu, you need to click "more", then you'll see "Developer", click on it. Afterwards you'll be presented with a page where your apps are listed under "My Applications" click on "See my applications". You can find all your API Key, secrets, and IDs there.

You can use rows and cols:

cout << "Width : " << src.cols << endl;
cout << "Height: " << src.rows << endl;

or size():

cout << "Width : " << src.size().width << endl;
cout << "Height: " << src.size().height << endl;

in my case: invalidateOptionsMenu just re-setted the text to the original one, but directly accessing the menu item and re-writing the desire text worked without problems:

if (mnuTopMenuActionBar_ != null) {
    MenuItem mnuPageIndex = mnuTopMenuActionBar_
        .findItem(R.id.menu_magazin_pageOfPage_text);

    if (mnuPageIndex != null) {
        if (getScreenOrientation() == 1) {
            mnuPageIndex.setTitle((i + 1) + " von " + pages);
        }
        else {
            mnuPageIndex.setTitle(
                (i + 1) + " + " + (i + 2) + " " + " von " + pages);
        }
        // invalidateOptionsMenu();
    }
}

due to the comment below, I was able to access the menu item via the following code:

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.magazine_swipe_activity, menu);
    mnuTopMenuActionBar_ = menu;
    return true;
}

Use a try catch block like below:

try { 

const phoneNumber = this.phoneUtil.parseAndKeepRawInput(value, this.countryCode);

}catch(e){}

tl;dr

The modern approach uses the java.time classes.

YearMonth.from(
    ZonedDateTime.parse( 
        "Mon Mar 14 16:02:37 GMT 2011" , 
        DateTimeFormatter.ofPattern( "E MMM d HH:mm:ss z uuuu" )
     )
).toString()

2011-03

Avoid legacy date-time classes

The modern way is with java.time classes. The old date-time classes such as Calendar have proven to be poorly-designed, confusing, and troublesome.

Define a custom formatter to match your string input.

String input = "Mon Mar 14 16:02:37 GMT 2011";
DateTimeFormatter f = DateTimeFormatter.ofPattern( "E MMM d HH:mm:ss z uuuu" );

Parse as a ZonedDateTime.

ZonedDateTime zdt = ZonedDateTime.parse( input , f );

You are interested in the year and month. The java.time classes include YearMonth class for that purpose.

YearMonth ym = YearMonth.from( zdt );

You can interrogate for the year and month numbers if needed.

int year = ym.getYear();
int month = ym.getMonthValue();

But the toString method generates a string in standard ISO 8601 format.

String output = ym.toString();

Put this all together.

String input = "Mon Mar 14 16:02:37 GMT 2011";
DateTimeFormatter f = DateTimeFormatter.ofPattern( "E MMM d HH:mm:ss z uuuu" );
ZonedDateTime zdt = ZonedDateTime.parse( input , f );
YearMonth ym = YearMonth.from( zdt );
int year = ym.getYear();
int month = ym.getMonthValue();

Dump to console.

System.out.println( "input: " + input );
System.out.println( "zdt: " + zdt );
System.out.println( "ym: " + ym );

input: Mon Mar 14 16:02:37 GMT 2011

zdt: 2011-03-14T16:02:37Z[GMT]

ym: 2011-03

See this code running in IdeOne.com.

Conversion

If you must have a Calendar object, you can convert to a GregorianCalendar using new methods added to the old classes.

GregorianCalendar gc = GregorianCalendar.from( zdt );

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to java.time.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

Where to obtain the java.time classes?

• Java SE 8 and SE 9 and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • The ThreeTenABP project adapts ThreeTen-Backport (mentioned above) for Android specifically.
  • See How to use….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

It is possible to do this by overwriting the Environment Table within a specified process itself.

As a proof of concept I wrote this sample app, which just edited a single (known) environment variable in a cmd.exe process:

typedef DWORD (__stdcall *NtQueryInformationProcessPtr)(HANDLE, DWORD, PVOID, ULONG, PULONG);

int __cdecl main(int argc, char* argv[])
{
    HMODULE hNtDll = GetModuleHandleA("ntdll.dll");
    NtQueryInformationProcessPtr NtQueryInformationProcess = (NtQueryInformationProcessPtr)GetProcAddress(hNtDll, "NtQueryInformationProcess");

    int processId = atoi(argv[1]);
    printf("Target PID: %u\n", processId);

    // open the process with read+write access
    HANDLE hProcess = OpenProcess(PROCESS_QUERY_LIMITED_INFORMATION | PROCESS_VM_READ | PROCESS_VM_WRITE | PROCESS_VM_OPERATION, 0, processId);
    if(hProcess == NULL)
    {
        printf("Error opening process (%u)\n", GetLastError());
        return 0;
    }

    // find the location of the PEB
    PROCESS_BASIC_INFORMATION pbi = {0};
    NTSTATUS status = NtQueryInformationProcess(hProcess, ProcessBasicInformation, &pbi, sizeof(pbi), NULL);
    if(status != 0)
    {
        printf("Error ProcessBasicInformation (0x%8X)\n", status);
    }
    printf("PEB: %p\n", pbi.PebBaseAddress);

    // find the process parameters
    char *processParamsOffset = (char*)pbi.PebBaseAddress + 0x20; // hard coded offset for x64 apps
    char *processParameters = NULL;
    if(ReadProcessMemory(hProcess, processParamsOffset, &processParameters, sizeof(processParameters), NULL))
    {
        printf("UserProcessParameters: %p\n", processParameters);
    }
    else
    {
        printf("Error ReadProcessMemory (%u)\n", GetLastError());
    }

    // find the address to the environment table
    char *environmentOffset = processParameters + 0x80; // hard coded offset for x64 apps
    char *environment = NULL;
    ReadProcessMemory(hProcess, environmentOffset, &environment, sizeof(environment), NULL);
    printf("environment: %p\n", environment);

    // copy the environment table into our own memory for scanning
    wchar_t *localEnvBlock = new wchar_t[64*1024];
    ReadProcessMemory(hProcess, environment, localEnvBlock, sizeof(wchar_t)*64*1024, NULL);

    // find the variable to edit
    wchar_t *found = NULL;
    wchar_t *varOffset = localEnvBlock;
    while(varOffset < localEnvBlock + 64*1024)
    {
        if(varOffset[0] == '\0')
        {
            // we reached the end
            break;
        }
        if(wcsncmp(varOffset, L"ENVTEST=", 8) == 0)
        {
            found = varOffset;
            break;
        }
        varOffset += wcslen(varOffset)+1;
    }

    // check to see if we found one
    if(found)
    {
        size_t offset = (found - localEnvBlock) * sizeof(wchar_t);
        printf("Offset: %Iu\n", offset);

        // write a new version (if the size of the value changes then we have to rewrite the entire block)
        if(!WriteProcessMemory(hProcess, environment + offset, L"ENVTEST=def", 12*sizeof(wchar_t), NULL))
        {
            printf("Error WriteProcessMemory (%u)\n", GetLastError());
        }
    }

    // cleanup
    delete[] localEnvBlock;
    CloseHandle(hProcess);

    return 0;
}

Sample output:

>set ENVTEST=abc

>cppTest.exe 13796
Target PID: 13796
PEB: 000007FFFFFD3000
UserProcessParameters: 00000000004B2F30
environment: 000000000052E700
Offset: 1528

>set ENVTEST
ENVTEST=def

Notes

This approach would also be limited to security restrictions. If the target is run at higher elevation or a higher account (such as SYSTEM) then we wouldn't have permission to edit its memory.

If you wanted to do this to a 32-bit app, the hard coded offsets above would change to 0x10 and 0x48 respectively. These offsets can be found by dumping out the _PEB and _RTL_USER_PROCESS_PARAMETERS structs in a debugger (e.g. in WinDbg dt _PEB and dt _RTL_USER_PROCESS_PARAMETERS)

To change the proof-of-concept into a what the OP needs, it would just enumerate the current system and user environment variables (such as documented by @tsadok's answer) and write the entire environment table into the target process' memory.

Edit: The size of the environment block is also stored in the _RTL_USER_PROCESS_PARAMETERS struct, but the memory is allocated on the process' heap. So from an external process we wouldn't have the ability to resize it and make it larger. I played around with using VirtualAllocEx to allocate additional memory in the target process for the environment storage, and was able to set and read an entirely new table. Unfortunately any attempt to modify the environment from normal means will crash and burn as the address no longer points to the heap (it will crash in RtlSizeHeap).

Try delete:

models.User.query.delete()

From the docs: Returns the number of rows deleted, excluding any cascades.

var time = moment().toDate();  // This will return a copy of the Date that the moment uses

time.setHours(0);
time.setMinutes(0);
time.setSeconds(0);
time.setMilliseconds(0);

Use the built in "InternalServerError" method (available in ApiController):

return InternalServerError();
//or...
return InternalServerError(new YourException("your message"));

For PostgreSQL example:

UPDATE TableA AS a
SET param_from_table_a=FALSE -- param FROM TableA
FROM TableB AS b
WHERE b.id=a.param_id AND a.amount <> 0; 

Back in computer class in high school, myself and a couple of friends taught the class how to program with Delphi. The class was mostly focused on programming with Pascal, so Delphi was a good next step. We demonstrated the event driven nature of Delphi and its RAD capabilities. At the end of the lesson we showed the class a sample application and asked them to reproduce it. The application asked "Are you drunk?" with two buttons Yes and No. ...I think you know what is coming next...the No button changed locations on mouse over and was almost impossible to click.

The students and teacher got a good kick out of it.

The program only required a few lines of user-written code with a simple equation to calculate where to move the button. I don't think any of the other students figured it out, but a few were close.

I'm gonna try to write this as a tutorial for you so it becomes easy to follow.

NOTE: This tutorial only works for older raspbian images. For the newer Raspbian based on Debian Buster see the following how-to in this thread: https://stackoverflow.com/a/58559140/869402

Pre-requirements

Before you start you need to make sure the following is installed:

apt-get install git rsync cmake libc6-i386 lib32z1 lib32stdc++6

Let's cross compile a Pie!

Start with making a folder in your home directory called raspberrypi.

Go in to this folder and pull down the ENTIRE tools folder you mentioned above:

git clone git://github.com/raspberrypi/tools.git

You wanted to use the following of the 3 ones, gcc-linaro-arm-linux-gnueabihf-raspbian, if I did not read wrong.

Go into your home directory and add:

export PATH=$PATH:$HOME/raspberrypi/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin

to the end of the file named ~/.bashrc

Now you can either log out and log back in (i.e. restart your terminal session), or run . ~/.bashrc in your terminal to pick up the PATH addition in your current terminal session.

Now, verify that you can access the compiler arm-linux-gnueabihf-gcc -v. You should get something like this:

Using built-in specs.

But hey! I did that and the libs still don't work!

We're not done yet! So far, we've only done the basics.

In your raspberrypi folder, make a folder called rootfs.

Now you need to copy the entire /liband /usr directory to this newly created folder. I usually bring the rpi image up and copy it via rsync:

rsync -rl --delete-after --safe-links [email protected]:/{lib,usr} $HOME/raspberrypi/rootfs

where 192.168.1.PI is replaced by the IP of your Raspberry Pi.

Now, we need to write a cmake config file. Open ~/home/raspberrypi/pi.cmake in your favorite editor and insert the following:

SET(CMAKE_SYSTEM_NAME Linux)
SET(CMAKE_SYSTEM_VERSION 1)
SET(CMAKE_C_COMPILER $ENV{HOME}/raspberrypi/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin/arm-linux-gnueabihf-gcc)
SET(CMAKE_CXX_COMPILER $ENV{HOME}/raspberrypi/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin/arm-linux-gnueabihf-g++)
SET(CMAKE_FIND_ROOT_PATH $ENV{HOME}/raspberrypi/rootfs)
SET(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)
SET(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
SET(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)

Now you should be able to compile your cmake programs simply by adding this extra flag: -D CMAKE_TOOLCHAIN_FILE=$HOME/raspberrypi/pi.cmake.

Using a cmake hello world example:

git clone https://github.com/jameskbride/cmake-hello-world.git 
cd cmake-hello-world
mkdir build
cd build
cmake -D CMAKE_TOOLCHAIN_FILE=$HOME/raspberrypi/pi.cmake ../
make
scp CMakeHelloWorld [email protected]:/home/pi/
ssh [email protected] ./CMakeHelloWorld

You can try Wolfram Alpha as in this example based on your input:

http://www.wolframalpha.com/input/?i=((A%20OR%20B)%20AND%20(NOT%20B%20AND%20C)%20OR%20C)&t=crmtb01&f=rc

Another option of course is to use Javascript (Jquery here):

$('.box1,.box2').each(function(){
    $(this).height($(this).parent().height());
})

The problem is that your ApplicationUser inherits from IdentityUser, which is defined like this:

IdentityUser : IdentityUser<string, IdentityUserLogin, IdentityUserRole, IdentityUserClaim>, IUser
....
public virtual ICollection<TRole> Roles { get; private set; }
public virtual ICollection<TClaim> Claims { get; private set; }
public virtual ICollection<TLogin> Logins { get; private set; }

and their primary keys are mapped in the method OnModelCreating of the class IdentityDbContext:

modelBuilder.Entity<TUserRole>()
            .HasKey(r => new {r.UserId, r.RoleId})
            .ToTable("AspNetUserRoles");

modelBuilder.Entity<TUserLogin>()
            .HasKey(l => new {l.LoginProvider, l.ProviderKey, l.UserId})
            .ToTable("AspNetUserLogins");

and as your DXContext doesn't derive from it, those keys don't get defined.

If you dig into the sources of Microsoft.AspNet.Identity.EntityFramework, you will understand everything.

I came across this situation some time ago, and I found three possible solutions (maybe there are more):

1. Use separate DbContexts against two different databases or the same database but different tables.
2. Merge your DXContext with ApplicationDbContext and use one database.
3. Use separate DbContexts against the same table and manage their migrations accordingly.

Option 1: See update the bottom.

Option 2: You will end up with a DbContext like this one:

public class DXContext : IdentityDbContext<User, Role,
    int, UserLogin, UserRole, UserClaim>//: DbContext
{
    public DXContext()
        : base("name=DXContext")
    {
        Database.SetInitializer<DXContext>(null);// Remove default initializer
        Configuration.ProxyCreationEnabled = false;
        Configuration.LazyLoadingEnabled = false;
    }

    public static DXContext Create()
    {
        return new DXContext();
    }

    //Identity and Authorization
    public DbSet<UserLogin> UserLogins { get; set; }
    public DbSet<UserClaim> UserClaims { get; set; }
    public DbSet<UserRole> UserRoles { get; set; }
    
    // ... your custom DbSets
    public DbSet<RoleOperation> RoleOperations { get; set; }

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        base.OnModelCreating(modelBuilder);

        modelBuilder.Conventions.Remove<PluralizingTableNameConvention>();
        modelBuilder.Conventions.Remove<OneToManyCascadeDeleteConvention>();

        // Configure Asp Net Identity Tables
        modelBuilder.Entity<User>().ToTable("User");
        modelBuilder.Entity<User>().Property(u => u.PasswordHash).HasMaxLength(500);
        modelBuilder.Entity<User>().Property(u => u.Stamp).HasMaxLength(500);
        modelBuilder.Entity<User>().Property(u => u.PhoneNumber).HasMaxLength(50);

        modelBuilder.Entity<Role>().ToTable("Role");
        modelBuilder.Entity<UserRole>().ToTable("UserRole");
        modelBuilder.Entity<UserLogin>().ToTable("UserLogin");
        modelBuilder.Entity<UserClaim>().ToTable("UserClaim");
        modelBuilder.Entity<UserClaim>().Property(u => u.ClaimType).HasMaxLength(150);
        modelBuilder.Entity<UserClaim>().Property(u => u.ClaimValue).HasMaxLength(500);
    }
}

Option 3: You will have one DbContext equal to the option 2. Let's name it IdentityContext. And you will have another DbContext called DXContext:

public class DXContext : DbContext
{        
    public DXContext()
        : base("name=DXContext") // connection string in the application configuration file.
    {
        Database.SetInitializer<DXContext>(null); // Remove default initializer
        Configuration.LazyLoadingEnabled = false;
        Configuration.ProxyCreationEnabled = false;
    }

    // Domain Model
    public DbSet<User> Users { get; set; }
    // ... other custom DbSets
    
    public static DXContext Create()
    {
        return new DXContext();
    }

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        base.OnModelCreating(modelBuilder);

        modelBuilder.Conventions.Remove<PluralizingTableNameConvention>();

        // IMPORTANT: we are mapping the entity User to the same table as the entity ApplicationUser
        modelBuilder.Entity<User>().ToTable("User"); 
    }

    public DbQuery<T> Query<T>() where T : class
    {
        return Set<T>().AsNoTracking();
    }
}

where User is:

public class User
{
    public int Id { get; set; }

    [Required, StringLength(100)]
    public string Name { get; set; }

    [Required, StringLength(128)]
    public string SomeOtherColumn { get; set; }
}

With this solution, I'm mapping the entity User to the same table as the entity ApplicationUser.

Then, using Code First Migrations you'll need to generate the migrations for the IdentityContext and THEN for the DXContext, following this great post from Shailendra Chauhan: Code First Migrations with Multiple Data Contexts

You'll have to modify the migration generated for DXContext. Something like this depending on which properties are shared between ApplicationUser and User:

        //CreateTable(
        //    "dbo.User",
        //    c => new
        //        {
        //            Id = c.Int(nullable: false, identity: true),
        //            Name = c.String(nullable: false, maxLength: 100),
        //            SomeOtherColumn = c.String(nullable: false, maxLength: 128),
        //        })
        //    .PrimaryKey(t => t.Id);
        AddColumn("dbo.User", "SomeOtherColumn", c => c.String(nullable: false, maxLength: 128));

and then running the migrations in order (first the Identity migrations) from the global.asax or any other place of your application using this custom class:

public static class DXDatabaseMigrator
{
    public static string ExecuteMigrations()
    {
        return string.Format("Identity migrations: {0}. DX migrations: {1}.", ExecuteIdentityMigrations(),
            ExecuteDXMigrations());
    }

    private static string ExecuteIdentityMigrations()
    {
        IdentityMigrationConfiguration configuration = new IdentityMigrationConfiguration();
        return RunMigrations(configuration);
    }

    private static string ExecuteDXMigrations()
    {
        DXMigrationConfiguration configuration = new DXMigrationConfiguration();
        return RunMigrations(configuration);
    }

    private static string RunMigrations(DbMigrationsConfiguration configuration)
    {
        List<string> pendingMigrations;
        try
        {
            DbMigrator migrator = new DbMigrator(configuration);
            pendingMigrations = migrator.GetPendingMigrations().ToList(); // Just to be able to log which migrations were executed

            if (pendingMigrations.Any())                
                    migrator.Update();     
        }
        catch (Exception e)
        {
            ExceptionManager.LogException(e);
            return e.Message;
        }
        return !pendingMigrations.Any() ? "None" : string.Join(", ", pendingMigrations);
    }
}

This way, my n-tier cross-cutting entities don't end up inheriting from AspNetIdentity classes, and therefore I don't have to import this framework in every project where I use them.

Sorry for the extensive post. I hope it could offer some guidance on this. I have already used options 2 and 3 in production environments.

UPDATE: Expand Option 1

For the last two projects I have used the 1st option: having an AspNetUser class that derives from IdentityUser, and a separate custom class called AppUser. In my case, the DbContexts are IdentityContext and DomainContext respectively. And I defined the Id of the AppUser like this:

public class AppUser : TrackableEntity
{
    [Key, DatabaseGenerated(DatabaseGeneratedOption.None)]
    // This Id is equal to the Id in the AspNetUser table and it's manually set.
    public override int Id { get; set; }

(TrackableEntity is the custom abstract base class that I use in the overridden SaveChanges method of my DomainContext context)

I first create the AspNetUser and then the AppUser. The drawback with this approach is that you have ensured that your "CreateUser" functionality is transactional (remember that there will be two DbContexts calling SaveChanges separately). Using TransactionScope didn't work for me for some reason, so I ended up doing something ugly but that works for me:

        IdentityResult identityResult = UserManager.Create(aspNetUser, model.Password);

        if (!identityResult.Succeeded)
            throw new TechnicalException("User creation didn't succeed", new LogObjectException(result));

        AppUser appUser;
        try
        {
            appUser = RegisterInAppUserTable(model, aspNetUser);
        }
        catch (Exception)
        {
            // Roll back
            UserManager.Delete(aspNetUser);
            throw;
        }

(Please, if somebody comes with a better way of doing this part I appreciate commenting or proposing an edit to this answer)

The benefits are that you don't have to modify the migrations and you can use any crazy inheritance hierarchy over the AppUser without messing with the AspNetUser. And actually, I use Automatic Migrations for my IdentityContext (the context that derives from IdentityDbContext):

public sealed class IdentityMigrationConfiguration : DbMigrationsConfiguration<IdentityContext>
{
    public IdentityMigrationConfiguration()
    {
        AutomaticMigrationsEnabled = true;
        AutomaticMigrationDataLossAllowed = false;
    }

    protected override void Seed(IdentityContext context)
    {
    }
}

This approach also has the benefit of avoiding to have your n-tier cross-cutting entities inheriting from AspNetIdentity classes.

JavaScript uses the \ (backslash) as an escape characters for:

• \' single quote
• \" double quote
• \ backslash
• \n new line
• \r carriage return
• \t tab
• \b backspace
• \f form feed
• \v vertical tab (IE < 9 treats '\v' as 'v' instead of a vertical tab ('\x0B'). If cross-browser compatibility is a concern, use \x0B instead of \v.)
• \0 null character (U+0000 NULL) (only if the next character is not a decimal digit; else it’s an octal escape sequence)

Note that the \v and \0 escapes are not allowed in JSON strings.

If you want to handle server errors globally, you may want to register an interceptor service for $httpProvider:

$httpProvider.interceptors.push(function ($q) {
    return {
        'responseError': function (rejection) {
            // do something on error
            if (canRecover(rejection)) {
                return responseOrNewPromise
            }
            return $q.reject(rejection);
        }
    };
});

Docs: http://docs.angularjs.org/api/ng.$http

Just summarising @libing's answer with a sample that worked for me.

val gson = Gson()
val todoItem: TodoItem = gson.fromJson(this.assets.readAssetsFile("versus.json"), TodoItem::class.java)

private fun AssetManager.readAssetsFile(fileName : String): String = open(fileName).bufferedReader().use{it.readText()}

Without this extension function the same can be achieved by using BufferedReader and InputStreamReader this way:

val i: InputStream = this.assets.open("versus.json")
val br = BufferedReader(InputStreamReader(i))
val todoItem: TodoItem = gson.fromJson(br, TodoItem::class.java)

no, but it runs fine on win64, and can create win64 .EXEs

Wouldn't lambdaj's project function do what you are looking for?

It'll look something like this:

List<UserDTO> userNDtos = project(users, UserDTO.class, on(User.class).getUserName(), on(User.class).getFullName(), .....);

(Define the constructor for UserDTO accordingly...)

Also see here for examples...

None of the existing answers worked for me with a single-line 10GB file. Grep runs out of memory even on a machine with 768 GB of RAM!

$ cat /proc/meminfo | grep MemTotal
MemTotal:       791236260 kB
$ ls -lh test.json
-rw-r--r-- 1 me all 9.2G Nov 18 15:54 test.json
$ grep -o '0,0,0,0,0,0,0,0,' test.json  | wc -l
grep: memory exhausted
0

So I wrote a very simple Rust program to do it.

1. Install Rust.
2. cargo install count_occurences

$ count_occurences '0,0,0,0,0,0,0,0,' test.json
99094198

It's a little slow (1 minute for 10GB), but at least it doesn't run out of memory!

Generating your own key from a byte array is easy:

byte[] raw = ...; // 32 bytes in size for a 256 bit key
Key skey = new javax.crypto.spec.SecretKeySpec(raw, "AES");

But creating a 256-bit key isn't enough. If the key generator cannot generate 256-bit keys for you, then the Cipher class probably doesn't support AES 256-bit either. You say you have the unlimited jurisdiction patch installed, so the AES-256 cipher should be supported (but then 256-bit keys should be too, so this might be a configuration problem).

Cipher cipher = Cipher.getInstance("AES");
cipher.init(Cipher.ENCRYPT_MODE, skey);
byte[] encrypted = cipher.doFinal(plainText.getBytes());

A workaround for lack of AES-256 support is to take some freely available implementation of AES-256, and use it as a custom provider. This involves creating your own Provider subclass and using it with Cipher.getInstance(String, Provider). But this can be an involved process.

Go to httpd.conf on /Applications/MAMP/conf/apache and see if the LoadModule rewrite_module modules/mod_rewrite.so line is un-commented (without the # at the beginning)

and change these from ...

    ServerName ...
    DocumentRoot /....
</VirtualHost>

To this:

<VirtualHost *:80>
    ServerAdmin ...
    ServerName ...

        Options FollowSymLinks
        AllowOverride None

Use npm update or, Run `npm install --save-dev @angular-devkit/build-angular

`

[contains(text(),'')] only returns true or false. It won't return any element results.

Just go to File -> Settings -> select Project Interpreter under Project tab -> click on the small gear icon -> Add -> System Interpreter -> select the python version you want in the drop down menu

this seemed to work for me

I believe the 2GB limit is for 32-bit Java. I thought v1.6 was always 64 bit, but try forcing 64 bit mode just to see: add the -d64 option.

I wasn't happy with any of the answers here, and went looking for a command-line solution.

In macOS Sierra 10.12, Apple introduced a new way for users to remap keys.

• No need to fiddle around with system GUIs
• No special privileges are required
• Completely customisable
• No need to install any 3rd-party crap like PCKeyboardHack / Seil / Karabiner / KeyRemap4MacBook / DoubleCommand / NoEjectDelay

If that sounds good to you, take a look at hidutil.

For example, to remap caps-lock to escape, refer to the key table and find that caps-lock has usage code 0x39 and escape has usage code 0x29. Put these codes or'd with the hex value 0x700000000 in the source and dest like this:

hidutil property --set '{"UserKeyMapping":[{"HIDKeyboardModifierMappingSrc":0x700000039,"HIDKeyboardModifierMappingDst":0x700000029}]}'

You may add other mappings in the same command. Personally, I like to remap caps-lock to backspace, and remap backspace to delete:

hidutil property --set '{"UserKeyMapping":[{"HIDKeyboardModifierMappingSrc":0x700000039,"HIDKeyboardModifierMappingDst":0x70000002A}, {"HIDKeyboardModifierMappingSrc":0x70000002A,"HIDKeyboardModifierMappingDst":0x70000004C}]}'

To see the current mapping:

hidutil property --get "UserKeyMapping"

Your changes will be lost at system reboot. If you want them to persist, configure them in a launch agent. Here's mine:

Thanks, Manish Kumar

In SQL Server direct division of two integer returns integer even if the result should be the float. There is an example below to get it across:

--1--
declare @weird_number_float float
set @weird_number_float=22/7
select @weird_number_float

--2--
declare @weird_number_decimal decimal(18,10)
set @weird_number_decimal=22/7 
select @weird_number_decimal

--3--
declare @weird_number_numeric numeric
set @weird_number_numeric=22/7 
select @weird_number_numeric

--Right way

declare @weird_number float
set @weird_number=cast(22 as float)/cast(7 as float)
select @weird_number

Just last block will return the 3,14285714285714. In spite of the second block defined with right precision the result will be 3.00000.

Try this:

Dim colHeader(12)
colHeader = ("A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L")

Unfortunately the code found online was VB.NET not VBA.

echo "discreet";history -d $(history 1)

Generally when I deal with stripping \r or \n, I'll look for both by doing something like

lines.gsub(/\r\n?/, "\n");

I've found that depending on how the data was saved (the OS used, editor used, Jupiter's relation to Io at the time) there may or may not be the newline after the carriage return. It does seem weird that you see both characters in hex mode. Hope this helps.

I assume you are using windows. Open the command prompt and type ipconfig and find out your local address (on your pc) it should look something like 192.168.1.13 or 192.168.0.5 where the end digit is the one that changes. It should be next to IPv4 Address.

If your WAMP does not use virtual hosts the next step is to enter that IP address on your phones browser ie http://192.168.1.13 If you have a virtual host then you will need root to edit the hosts file.

If you want to test the responsiveness / mobile design of your website you can change your user agent in chrome or other browsers to mimic a mobile.

See http://googlesystem.blogspot.co.uk/2011/12/changing-user-agent-new-google-chrome.html.

Edit: Chrome dev tools now has a mobile debug tool where you can change the size of the viewport, spoof user agents, connections (4G, 3G etc).

If you get forbidden access then see this question WAMP error: Forbidden You don't have permission to access /phpmyadmin/ on this server. Basically, change the occurrances of deny,allow to allow,deny in the httpd.conf file. You can access this by the WAMP menu.

To eliminate possible causes of the issue for now set your config file to

<Directory />
    Options FollowSymLinks
    AllowOverride All
    Order allow,deny
    Allow from all
    <RequireAll>
        Require all granted
    </RequireAll>
</Directory>

As thatis working for my windows PC, if you have the directory config block as well change that also to allow all.

Config file that fixed the problem:

https://gist.github.com/samvaughton/6790739

Problem was that the /www apache directory config block still had deny set as default and only allowed from localhost.

To get the number of columns or last column's index:

var numColumns = sheet.getLastColumn()

To get the no of rows or last row's index:

var numRows = sheet.getLastRow()

where

var sheet = SpreadsheetApp.getActiveSheet()

My guess is, somehow the document is not fully loaded by the time the method is called. Have your code executing after the document is ready event.

I used below method, which doesn't require any change in config, tested on mysql-5.5.51-winx64 and 5.5.50-MariaDB:

put 'load data...' in .sql file (ex: LoadTableName.sql)

LOAD DATA INFILE 'D:\\Work\\TableRecords.csv' INTO TABLE tbl1 FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY '\r\n' IGNORE 1 LINES (col1,col2);

then:

mysql -uroot -pStr0ngP@ss -Ddatabasename -e "source D:\Work\LoadTableName.sql"

private void dataGridView1_CellContextMenuStripNeeded(object sender, 
DataGridViewCellContextMenuStripNeededEventArgs e)
{            
    if (e.RowIndex != -1)
    {
        dataGridView1.ClearSelection();
        this.dataGridView1.Rows[e.RowIndex].Selected = true;
        e.ContextMenuStrip = contextMenuStrip1;
    }
}

DOS/Windows: use Code page

chcp 65001>NUL
type ascii.txt > unicode.txt

Command chcp can be used to change the code page. Code page 65001 is Microsoft name for UTF-8. After setting code page, the output generated by following commands will be of code page set.

You can simply use the WebDriver object, and access to the page source code via its @property field page_source...

Try this code snippet :-)

from selenium import webdriver
driver = webdriver.Firefox('path/to/executable')
driver.get('https://some-domain.com')
source = driver.page_source
if 'stuff' in source:
    print('found...')
else:
    print('not in source...')

Perhaps another way to code conditional constructs in XML:

<rule>
    <if>
        <conditions>
            <condition var="something" operator="&gt;">400</condition>
            <!-- more conditions possible -->
        </conditions>
        <statements>
            <!-- do something -->
        </statements>
    </if>
    <elseif>
        <conditions></conditions>
        <statements></statements>
    </elseif>
    <else>
        <statements></statements>
    </else>
</rule>

This is not difficult to achieve, but you need to use the javascript onmouseover function. Pseudoscript:

<div class="section ">

<div class="image"><img src="myImage.jpg" onmouseover=".layer {border: 1px solid black;} .image {border: 1px solid black;}" /></div>

<div class="layer">Lorem Ipsum</div>

</div>

Use your own colors. You can also reference javascript functions in the mouseover command.

To extend the answer above and if the case is you are using XAMPP. In the current version of the xampp you cannot locate the curl_exec in the php.ini, just try using

<?php
echo '<pre>';
var_dump(curl_version());
echo '</pre>';
?>

and save to your htdocs. Next go to your browser and paste

http://localhost/[your_filename].php

if the result looks like this

array(9) {
  ["version_number"]=>
  int(469760)
  ["age"]=>
  int(3)
  ["features"]=>
  int(266141)

If you don't add .0f it will be treated like it is an integer, and an integer division is a lot different from a floating point division indeed :)

float percent = (n * 100.0f) / v;

If you need an integer out of this you can of course cast the float or the double again in integer.

int percent = (int)((n * 100.0f) / v);

If you know your n value is less than 21474836 (that is (2 ^ 31 / 100)), you can do all using integer operations.

int percent = (n * 100) / v;

If you get NaN is because wathever you do you cannot divide for zero of course... it doesn't make sense.

If you don't know the row number, but do know some values then you can use subset

x <- structure(list(A = c(5,    3.5, 3.25, 4.25,  1.5 ), 
                    B = c(4.25, 4,   4,    4.5,   4.5 ),
                    C = c(4.5,  2.5, 4,    2.25,  3   )
               ),
               .Names    = c("A", "B", "C"),
               class     = "data.frame",
               row.names = c(NA, -5L)
     )

subset(x, A ==5 & B==4.25 & C==4.5)

You should be able to do it using the X-UA meta tag:

<meta http-equiv="X-UA-Compatible" content="IE=9" />

However, if you find yourself having to do this, you're probably doing something wrong and should take a look at what you're doing and see if you can do it a different/better way.

When creating a file, use slashes to specify the directory. For example:

Name the file:

repositoryname/newfoldername/filename

GitHub will automatically create a folder with the name newfoldername.

I made a solution for this.

The Drag and Drop functionality for this method only works with Chrome, Firefox and Safari. (Don't know if it works with IE10), but for other browsers, the "Or click here" button works fine.

The input field simply follow your mouse when dragging a file over an area, and I've added a button as well..

Uncomment opacity:0; the file input is only visible so you can see what's going on.

If you want to play with the thread stack size, you'll want to look at the -Xss option on the Hotspot JVM. It may be something different on non Hotspot VM's since the -X parameters to the JVM are distribution specific, IIRC.

On Hotspot, this looks like java -Xss16M if you want to make the size 16 megs.

Type java -X -help if you want to see all of the distribution specific JVM parameters you can pass in. I am not sure if this works the same on other JVMs, but it prints all of Hotspot specific parameters.

For what it's worth - I would recommend limiting your use of recursive methods in Java. It's not too great at optimizing them - for one the JVM doesn't support tail recursion (see Does the JVM prevent tail call optimizations?). Try refactoring your factorial code above to use a while loop instead of recursive method calls.

var keys = new Array();
for(var key in obj)
{
   keys[keys.length] = key;
}

var keyLength = keys.length;

to access any value from the object, you can use obj[key];

Try

SELECT EXTRACTVALUE(xmltype(testclob), '/DCResponse/ContextData/Field[@key="Decision"]') 
FROM traptabclob;

Here is a sqlfiddle demo

Here's probably what you are looking for: php-get-url-query-string. You can combine it with other suggested $_SERVER parameters.

It's even easier than everything suggested above. Data attributes in MVC which include dashes (-) are catered for with the use of underscore (_).

<%= Html.ActionLink("« Previous", "Search",
 new { keyword = Model.Keyword, page = Model.currPage - 1},
 new { @class = "prev", data_details = "Some Details"   })%>

I see JohnnyO already mentioned this.

Try this:

one year free. I do use this for a while.

See if the BSD C Standard Library has fcvt(). You could start with the source for it that rather than writing your code from scratch. The UNIX 98 standard fcvt() apparently does not output scientific notation so you would have to implement it yourself, but I don't think it would be hard.

echo -e '$d\nw\nq'| ed foo.txt

As of version 1.5.1, I'm able to access all the sockets in a namespace with:

var socket_ids = Object.keys(io.of('/namespace').sockets);
socket_ids.forEach(function(socket_id) {
    var socket = io.of('/namespace').sockets[socket_id];
    if (socket.connected) {
        // Do something...
    }
});

For some reason, they're using a plain object instead of an array to store the socket IDs.

If you have too many installers to find what you are looking for easily, here is some powershell to provide a filter and narrow it down a little by display name.

$filter = "*core*sdk*"; (Get-ChildItem HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall).Name | % { $path = "Registry::$_"; Get-ItemProperty $path } | Where-Object { $_.DisplayName -like $filter } | Select-Object -Property DisplayName, PsChildName

@Artilheiro : If its a navigationbased project, u can create BaseViewController. All other view will inherit this BaseView. In BaseView u can define generic methods to add right button or to change left button text.

ex:

@interface BaseController : UIViewController {

} - (void) setBackButtonCaption:(NSString *)caption;

(void) setRightButtonCaption:(NSString *)caption selectot:(SEL )selector;

@end // In BaseView.M

(void) setBackButtonCaption:(NSString *)caption {

UIBarButtonItem *backButton =[[UIBarButtonItem alloc] init];

backButton.title= caption;
self.navigationItem.backBarButtonItem = backButton;
[backButton release];

} - (void) setRightButtonCaption:(NSString *)caption selectot:(SEL )selector {

  UIBarButtonItem *rightButton = [[UIBarButtonItem alloc] init];

rightButton.title = caption;

rightButton.target= self;

[rightButton setAction:selector];

self.navigationItem.rightBarButtonItem= rightButton;

[rightButton release];

}

And now in any custom view, implement this base view call the methods:

@interface LoginView : BaseController {

In some method call base method as:

SEL sel= @selector(switchToForgotPIN);

[super setRightButtonCaption:@"Forgot PIN" selectot:sel];

Using your code with some random data, this would work:

fig, axs = plt.subplots(2,5, figsize=(15, 6), facecolor='w', edgecolor='k')
fig.subplots_adjust(hspace = .5, wspace=.001)

axs = axs.ravel()

for i in range(10):

    axs[i].contourf(np.random.rand(10,10),5,cmap=plt.cm.Oranges)
    axs[i].set_title(str(250+i))

The layout is off course a bit messy, but that's because of your current settings (the figsize, wspace etc).

A complete beginner like myself to the topic may find it harder to implement one of these answers than, if within your control, to resize the image yourself with an online editor or a photo editor like Photoshop.

A 500x500 image will appear larger on the map than a 50x50 image.

No programming required.

You need to add an instance of the class:

lstemail.Add(new EmailData { FirstName = "John", LastName = "Smith", Location = "Los Angeles"});

I would recommend adding a constructor to your class, however:

public class EmailData
{
    public EmailData(string firstName, string lastName, string location)
    {
        this.FirstName = firstName;
        this.LastName = lastName;
        this.Location = location;
    }
    public string FirstName{ set; get; }
    public string LastName { set; get; }
    public string Location{ set; get; }
}

This would allow you to write the addition to your list using the constructor:

lstemail.Add(new EmailData("John", "Smith", "Los Angeles"));

In my case after spending many days on this issues a gentleman help on this issue below is the solution and it worked for me. Issue: While trying to connect SqlServer DB with Service account authentication using spring boot it throws below exception.

com.microsoft.sqlserver.jdbc.SQLServerException: This driver is not configured for integrated authentication. ClientConnectionId:ab942951-31f6-44bf-90aa-7ac4cec2e206 at com.microsoft.sqlserver.jdbc.SQLServerConnection.terminate(SQLServerConnection.java:2392) ~[mssql-jdbc-6.1.0.jre8.jar!/:na] Caused by: java.lang.UnsatisfiedLinkError: sqljdbc_auth (Not found in java.library.path) at java.lang.ClassLoader.loadLibraryWithPath(ClassLoader.java:1462) ~[na:2.9 (04-02-2020)] Solution: Use JTDS driver with the following steps

1. Use JTDS driver insteadof sqlserver driver.

   ----------------- Dedicated Pick Update properties PROD using JTDS ----------------

   datasource.dedicatedpicup.url=jdbc:jtds:sqlserver://YourSqlServer:PortNo/DatabaseName;instance=InstanceName;domain=DomainName
   datasource.dedicatedpicup.jdbcUrl=${datasource.dedicatedpicup.url}
   datasource.dedicatedpicup.username=$da-XYZ
   datasource.dedicatedpicup.password=ENC(XYZ)
   datasource.dedicatedpicup.driver-class-name=net.sourceforge.jtds.jdbc.Driver
   

2. Remove Hikari in configuration properties.

   #datasource.dedicatedpicup.hikari.connection-timeout=60000 #datasource.dedicatedpicup.hikari.maximum-pool-size=5

3. Add sqljdbc4 dependency.

   com.microsoft.sqlserver sqljdbc4 4.0

4. Add Tomcatjdbc dependency.

   org.apache.tomcat tomcat-jdbc

5. Exclude HikariCP from spring-boot-starter-jdbc dependency.

   org.springframework.boot spring-boot-starter-jdbc com.zaxxer HikariCP

Without adding additional dependencies, this works. You don't need Volley for this. This works using the current version of Kotlin as of Dec 2018: Kotlin 1.3.10

If using Android Studio, you'll need to add this declaration in your AndroidManifest.xml:

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

You should manually declare imports here. The auto-import tool caused me many conflicts.:

import android.os.AsyncTask
import java.io.BufferedReader
import java.io.InputStreamReader
import java.io.OutputStream
import java.io.OutputStreamWriter
import java.net.URL
import java.net.URLEncoder
import javax.net.ssl.HttpsURLConnection

You can't perform network requests on a background thread. You must subclass AsyncTask.

To call the method:

NetworkTask().execute(requestURL, queryString)

Declaration:

private class NetworkTask : AsyncTask<String, Int, Long>() {
    override fun doInBackground(vararg parts: String): Long? {
        val requestURL = parts.first()
        val queryString = parts.last()

        // Set up request
        val connection: HttpsURLConnection = URL(requestURL).openConnection() as HttpsURLConnection
        // Default is GET so you must override this for post
        connection.requestMethod = "POST"
        // To send a post body, output must be true
        connection.doOutput = true
        // Create the stream
        val outputStream: OutputStream = connection.outputStream
        // Create a writer container to pass the output over the stream
        val outputWriter = OutputStreamWriter(outputStream)
        // Add the string to the writer container
        outputWriter.write(queryString)
        // Send the data
        outputWriter.flush()

        // Create an input stream to read the response
        val inputStream = BufferedReader(InputStreamReader(connection.inputStream)).use {
            // Container for input stream data
            val response = StringBuffer()
            var inputLine = it.readLine()
            // Add each line to the response container
            while (inputLine != null) {
                response.append(inputLine)
                inputLine = it.readLine()
            }
            it.close()
            // TODO: Add main thread callback to parse response
            println(">>>> Response: $response")
        }
        connection.disconnect()

        return 0
    }

    protected fun onProgressUpdate(vararg progress: Int) {
    }

    override fun onPostExecute(result: Long?) {
    }
}

keywords = [1,2,3,4];
doc.array.pull(1) //this remove one item from a array
doc.array.pull(...keywords) // this remove multiple items in a array

if you want to use ... you should call 'use strict'; at the top of your js file; :)

I landed here because of an XCTestCase, in which I'd disabled most of the tests by prefixing them with 'no_' as in no_testBackgroundAdding. Once I noticed that most of the answers had something to do with locks and threading, I realized the test contained a few instances of XCTestExpectation with corresponding waitForExpectations. They were all in the disabled tests, but apparently Xcode was still evaluating them at some level.

In the end I found an XCTestExpectation that was defined as @property but lacked the @synthesize. Once I added the synthesize directive, the EXC_BAD_INSTRUCTION disappeared.

Most basic example (live example here):

CSS:

    #wrapper {
        width: 500px;
        margin: 0 auto;
    }

HTML:

    <body>
        <div id="wrapper">
            Piece of text inside a 500px width div centered on the page
        </div>
    </body>

How the principle works:

Create your wrapper and assign it a certain width. Then apply an automatic horizontal margin to it by using margin: 0 auto; or margin-left: auto; margin-right: auto;. The automatic margins make sure your element is centered.

Yes. For example you can use the solution by https://grabz.it.

It's got a Javascript API which can be used in different ways to grab and manipulate the screenshot. In order to use it in your app you will need to first get an app key and secret and download the free Javascript SDK.

So, let's see a simple example for using it:

//first include the grabzit.min.js library in the web page
<script src="grabzit.min.js"></script>
//include the code below to add the screenshot to the body tag    
<script>
//use secret key to sign in. replace the url.
GrabzIt("Sign in to view your Application Key").ConvertURL("http://www.google.com").Create();
</script>

Then simply wait a short while and the image will automatically appear at the bottom of the page, without you needing to reload the page.

That's the simplest one. For more examples with image manipulation, attaching screenshots to elements and etc check the documentation.

You cannot straightly query mongodb collections by date components like day or month. But its possible by using the special $where javascript expression

db.mydatabase.mycollection.find({$where : function() { return this.date.getMonth() == 11} })

or simply

db.mydatabase.mycollection.find({$where : 'return this.date.getMonth() == 11'})

(But i prefer the first one)

Check out the below shell commands to get the parts of date

>date = ISODate("2011-09-25T10:12:34Z")
> date.getYear()
111
> date.getMonth()
8
> date.getdate()
25

EDIT:

Use $where only if you have no other choice. It comes with the performance problems. Please check out the below comments by @kamaradclimber and @dcrosta. I will let this post open so the other folks get the facts about it.

and check out the link $where Clauses and Functions in Queries for more info

This will generate 4 MB text file with random characters in current directory and its name "4mb.txt" You can change parameters to generate different sizes and names.

It says all the requests to go through WicketFilter

Also, if you use wicket WicketApplication for application level settings. Like URL patterns and things that are true at app level

This is what you need really, http://wicket.apache.org/learn/examples/helloworld.html

In addition to existing good answers, note that Jackson 1.9 improved handling by adding "property unification", meaning that ALL annotations from difference parts of a logical property are combined, using (hopefully) intuitive precedence.

In Jackson 1.8 and prior, only field and getter annotations were used when determining what and how to serialize (writing JSON); and only and setter annotations for deserialization (reading JSON). This sometimes required addition of "extra" annotations, like annotating both getter and setter.

With Jackson 1.9 and above these extra annotations are NOT needed. It is still possible to add those; and if different names are used, one can create "split" properties (serializing using one name, deserializing using other): this is occasionally useful for sort of renaming.

I came across this post by Minko Gechev which clearly explains the major differences.

Do this instead:

values = [[1,2,3],[4,5]]
for x in values:
    if len(x) == 3:
       print(x)

Look for this:

ANY page in your project that has a missing, or different Namespace...

If you have ANY page in your project with <NO Namespace> , OR a

DIFFERENT Namespace than Default.aspx, you will get this

"Cannot load Default.aspx", or this: "Default.aspx does not belong here".

ALSO: If you have a Redirect to a page in your Solution/Project and the page which is to be Redirected To has a bad namespace -- you may not get a compiler error, until you try and run. If the Redirect is removed or commented-out, the error goes away...

BTW -- What the hell do these error messages mean? Is this MS.Access, with the "misdirection" -- ??

tl;dr:

concat and append currently sort the non-concatenation index (e.g. columns if you're adding rows) if the columns don't match. In pandas 0.23 this started generating a warning; pass the parameter sort=True to silence it. In the future the default will change to not sort, so it's best to specify either sort=True or False now, or better yet ensure that your non-concatenation indices match.

The warning is new in pandas 0.23.0:

In a future version of pandas pandas.concat() and DataFrame.append() will no longer sort the non-concatenation axis when it is not already aligned. The current behavior is the same as the previous (sorting), but now a warning is issued when sort is not specified and the non-concatenation axis is not aligned, link.

More information from linked very old github issue, comment by smcinerney :

When concat'ing DataFrames, the column names get alphanumerically sorted if there are any differences between them. If they're identical across DataFrames, they don't get sorted.

This sort is undocumented and unwanted. Certainly the default behavior should be no-sort.

After some time the parameter sort was implemented in pandas.concat and DataFrame.append:

sort : boolean, default None

Sort non-concatenation axis if it is not already aligned when join is 'outer'. The current default of sorting is deprecated and will change to not-sorting in a future version of pandas.

Explicitly pass sort=True to silence the warning and sort. Explicitly pass sort=False to silence the warning and not sort.

This has no effect when join='inner', which already preserves the order of the non-concatenation axis.

So if both DataFrames have the same columns in the same order, there is no warning and no sorting:

df1 = pd.DataFrame({"a": [1, 2], "b": [0, 8]}, columns=['a', 'b'])
df2 = pd.DataFrame({"a": [4, 5], "b": [7, 3]}, columns=['a', 'b'])

print (pd.concat([df1, df2]))
   a  b
0  1  0
1  2  8
0  4  7
1  5  3

df1 = pd.DataFrame({"a": [1, 2], "b": [0, 8]}, columns=['b', 'a'])
df2 = pd.DataFrame({"a": [4, 5], "b": [7, 3]}, columns=['b', 'a'])

print (pd.concat([df1, df2]))
   b  a
0  0  1
1  8  2
0  7  4
1  3  5

But if the DataFrames have different columns, or the same columns in a different order, pandas returns a warning if no parameter sort is explicitly set (sort=None is the default value):

df1 = pd.DataFrame({"a": [1, 2], "b": [0, 8]}, columns=['b', 'a'])
df2 = pd.DataFrame({"a": [4, 5], "b": [7, 3]}, columns=['a', 'b'])

print (pd.concat([df1, df2]))

FutureWarning: Sorting because non-concatenation axis is not aligned.

   a  b
0  1  0
1  2  8
0  4  7
1  5  3

print (pd.concat([df1, df2], sort=True))
   a  b
0  1  0
1  2  8
0  4  7
1  5  3

print (pd.concat([df1, df2], sort=False))
   b  a
0  0  1
1  8  2
0  7  4
1  3  5

If the DataFrames have different columns, but the first columns are aligned - they will be correctly assigned to each other (columns a and b from df1 with a and b from df2 in the example below) because they exist in both. For other columns that exist in one but not both DataFrames, missing values are created.

Lastly, if you pass sort=True, columns are sorted alphanumerically. If sort=False and the second DafaFrame has columns that are not in the first, they are appended to the end with no sorting:

df1 = pd.DataFrame({"a": [1, 2], "b": [0, 8], 'e':[5, 0]}, 
                    columns=['b', 'a','e'])
df2 = pd.DataFrame({"a": [4, 5], "b": [7, 3], 'c':[2, 8], 'd':[7, 0]}, 
                    columns=['c','b','a','d'])

print (pd.concat([df1, df2]))

                                                       .append(placement_by_video_summary_new, sort=True)
                                                       .sort_index()

In addition to David Sacks answer, you may also need to go to the Build tab of the Project Properties and set Platform Target to x86 for the project that is giving you these warnings. Though you might expect it to be, this setting does not seem to be perfectly synchronized with the setting in the configuration manager.

By the way, it is free :)

But, I think you should ask this on serverfault.com instead

In my case, I wanted a one liner that I could run from the commandline (actually via a Makefile). Here is an example installing "VGAM" and "feather" if they are not already installed:

R -e 'for (p in c("VGAM", "feather")) if (!require(p, character.only=TRUE)) install.packages(p, repos="http://cran.us.r-project.org")'

From within R it would just be:

for (p in c("VGAM", "feather")) if (!require(p, character.only=TRUE)) install.packages(p, repos="http://cran.us.r-project.org")

There is nothing here beyond the previous solutions except that:

• I keep it to a single line
• I hard code the repos parameter (to avoid any popups asking about the mirror to use)
• I don't bother to define a function to be used elsewhere

Also note the important character.only=TRUE (without it, the require would try to load the package p).

Somehow your requirement sounds a bit contradictory ..

group by name (which is basically a distinct on name plus readiness to aggregate) and then a distinct on IP

What do you think should happen if two people (names) worked from the same IP within the time period specified?

Did you try this?

SELECT name, COUNT(name), time, price, ip, SUM(price) 
  FROM tablename 
 WHERE time >= $yesterday AND time <$today 
GROUP BY name,ip

//Here is some simple sample code for update

//First declare this

private SQLiteDatabase db;

//initialize the following

        db=dbhelper.getWritableDatabase();

//updation code

 ContentValues values= new ContentValues();
                values.put(DatabaseAppHelper.KEY_PEDNAME, ped_name);
                values.put(DatabaseAppHelper.KEY_PEDPHONE, ped_phone);
                values.put(DatabaseAppHelper.KEY_PEDLOCATION, ped_location);
                values.put(DatabaseAppHelper.KEY_PEDEMAIL, ped_emailid);
                db.update(DatabaseAppHelper.TABLE_NAME, values,  DatabaseAppHelper.KEY_ID + "=" + ?, null);

//put ur id instead of the 'question mark' is a function in my shared preference.

setattr(x, attr, 'magic')

For help on it:

>>> help(setattr)
Help on built-in function setattr in module __builtin__:

setattr(...)
    setattr(object, name, value)

    Set a named attribute on an object; setattr(x, 'y', v) is equivalent to
    ``x.y = v''.

Edit: However, you should note (as pointed out in a comment) that you can't do that to a "pure" instance of object. But it is likely you have a simple subclass of object where it will work fine. I would strongly urge the O.P. to never make instances of object like that.

ORACLE_HOME needs to be at the top level of the Oracle directory structure for the database installation. From that point, Oracle knows how to find all the other files it needs. For example, the error message you get is because Oracle can't locate the message files to report errors with (should be in the various mesg directories below the oracle home. Instead of the above value you give, I would try

export ORACLE_HOME=/usr/lib/oracle/xe/app/oracle/product/10.2.0

Json.NET does this...

Dictionary<string, string> values = new Dictionary<string, string>();
values.Add("key1", "value1");
values.Add("key2", "value2");

string json = JsonConvert.SerializeObject(values);
// {
//   "key1": "value1",
//   "key2": "value2"
// }

More examples: Serializing Collections with Json.NET

If you don't use the STL, then the code looks a lot bit like C.

#include <cstdlib>
#include <new>

template< class T >
void append_to_array( T *&arr, size_t &n, T const &obj ) {
    T *tmp = static_cast<T*>( std::realloc( arr, sizeof(T) * (n+1) ) );
    if ( tmp == NULL ) throw std::bad_alloc( __FUNCTION__ );
       // assign things now that there is no exception
    arr = tmp;
    new( &arr[ n ] ) T( obj ); // placement new
    ++ n;
}

T can be any POD type, including pointers.

Note that arr must be allocated by malloc, not new[].

In Kotlin,you can use using alpha like this,

   //Click on On.//
    view.rel_on.setOnClickListener{
        view.rel_off.alpha= 0.2F
        view.rel_on.alpha= 1F

    }

    //Click on Off.//
    view.rel_off.setOnClickListener {
        view.rel_on.alpha= 0.2F
        view.rel_off.alpha= 1F
    }

Result is like in this screen shots.

Hope this will help you.Thanks

Use EmailMultiAlternatives and render_to_string to make use of two alternative templates (one in plain text and one in html):

from django.core.mail import EmailMultiAlternatives
from django.template import Context
from django.template.loader import render_to_string

c = Context({'username': username})    
text_content = render_to_string('mail/email.txt', c)
html_content = render_to_string('mail/email.html', c)

email = EmailMultiAlternatives('Subject', text_content)
email.attach_alternative(html_content, "text/html")
email.to = ['[email protected]']
email.send()

Look up the new HTML5 Input Types. These instruct browsers to perform client-side filtering of data, but the implementation is incomplete across different browsers. The pattern attribute will do regex-style filtering, but, again, browsers don't fully (or at all) support it.

However, these won't block the input itself, it will simply prevent submitting the form with the invalid data. You'll still need to trap the onkeydown event to block key input before it displays on the screen.

Something like this should work

var text = $('#toptitle').text();
if (text == 'Profil'){
    $('#toptitle').text('New Word');
}

$('#myId').val() should do it, failing that I would try:

$('#myId option:selected').val()

FileReader r = new FileReader(file);

Use a file reader load the file and then write its contents to a string buffer.

The link above shows you an example of how to accomplish this. As other post to this answer say to load a file into memory you do not need write access as long as you do not plan on making changes to the actual file.

If you want to use the dot renderer. There are alternatives like neato and twopi. If graphiz isn't in your path, figure out where it is installed and run it from there.

You can change the output format by varying the value after -T and choosing an appropriate filename extension after -o.

If you're using windows, check out the installed tool called GVEdit, it makes the whole process slightly easier.

Go look at the graphviz site in the section called "User's Guides" for more detail on how to use the tools:

http://www.graphviz.org/documentation/

(See page 27 for output formatting for the dot command, for instance)

http://www.graphviz.org/pdf/dotguide.pdf

It depends on the virtual machine, but it's easy to adapt the code from a similar question asking about bytes in Java:

class LotsOfBooleans
{
    boolean a0, a1, a2, a3, a4, a5, a6, a7, a8, a9, aa, ab, ac, ad, ae, af;
    boolean b0, b1, b2, b3, b4, b5, b6, b7, b8, b9, ba, bb, bc, bd, be, bf;
    boolean c0, c1, c2, c3, c4, c5, c6, c7, c8, c9, ca, cb, cc, cd, ce, cf;
    boolean d0, d1, d2, d3, d4, d5, d6, d7, d8, d9, da, db, dc, dd, de, df;
    boolean e0, e1, e2, e3, e4, e5, e6, e7, e8, e9, ea, eb, ec, ed, ee, ef;
}

class LotsOfInts
{
    int a0, a1, a2, a3, a4, a5, a6, a7, a8, a9, aa, ab, ac, ad, ae, af;
    int b0, b1, b2, b3, b4, b5, b6, b7, b8, b9, ba, bb, bc, bd, be, bf;
    int c0, c1, c2, c3, c4, c5, c6, c7, c8, c9, ca, cb, cc, cd, ce, cf;
    int d0, d1, d2, d3, d4, d5, d6, d7, d8, d9, da, db, dc, dd, de, df;
    int e0, e1, e2, e3, e4, e5, e6, e7, e8, e9, ea, eb, ec, ed, ee, ef;
}


public class Test
{
    private static final int SIZE = 1000000;

    public static void main(String[] args) throws Exception
    {        
        LotsOfBooleans[] first = new LotsOfBooleans[SIZE];
        LotsOfInts[] second = new LotsOfInts[SIZE];

        System.gc();
        long startMem = getMemory();

        for (int i=0; i < SIZE; i++)
        {
            first[i] = new LotsOfBooleans();
        }

        System.gc();
        long endMem = getMemory();

        System.out.println ("Size for LotsOfBooleans: " + (endMem-startMem));
        System.out.println ("Average size: " + ((endMem-startMem) / ((double)SIZE)));

        System.gc();
        startMem = getMemory();
        for (int i=0; i < SIZE; i++)
        {
            second[i] = new LotsOfInts();
        }
        System.gc();
        endMem = getMemory();

        System.out.println ("Size for LotsOfInts: " + (endMem-startMem));
        System.out.println ("Average size: " + ((endMem-startMem) / ((double)SIZE)));

        // Make sure nothing gets collected
        long total = 0;
        for (int i=0; i < SIZE; i++)
        {
            total += (first[i].a0 ? 1 : 0) + second[i].a0;
        }
        System.out.println(total);
    }

    private static long getMemory()
    {
        Runtime runtime = Runtime.getRuntime();
        return runtime.totalMemory() - runtime.freeMemory();
    }
}

To reiterate, this is VM-dependent, but on my Windows laptop running Sun's JDK build 1.6.0_11 I got the following results:

Size for LotsOfBooleans: 87978576
Average size: 87.978576
Size for LotsOfInts: 328000000
Average size: 328.0

That suggests that booleans can basically be packed into a byte each by Sun's JVM.

JOIN

When using JOIN against an entity associations, JPA will generate a JOIN between the parent entity and the child entity tables in the generated SQL statement.

So, taking your example, when executing this JPQL query:

FROM Employee emp
JOIN emp.department dep

Hibernate is going to generate the following SQL statement:

SELECT emp.*
FROM employee emp
JOIN department dep ON emp.department_id = dep.id

Note that the SQL SELECT clause contains only the employee table columns, and not the department ones. To fetch the department table columns, we need to use JOIN FETCH instead of JOIN.

JOIN FETCH

So, compared to JOIN, the JOIN FETCH allows you to project the joining table columns in the SELECT clause of the generated SQL statement.

So, in your example, when executing this JPQL query:

FROM Employee emp
JOIN FETCH emp.department dep

Hibernate is going to generate the following SQL statement:

SELECT emp.*, dept.*
FROM employee emp
JOIN department dep ON emp.department_id = dep.id

Note that, this time, the department table columns are selected as well, not just the ones associated with the entity listed in the FROM JPQL clause.

Also, JOIN FETCH is a great way to address the LazyInitializationException when using Hibernate as you can initialize entity associations using the FetchType.LAZY fetching strategy along with the main entity you are fetching.

I ran across this post today as I was running into the same issue and had the same problem of the javascript not running with the CDATA tags listed above. I corrected the CDATA tags to look like:

<script type="text/javascript">
//<![CDATA[ 

your javascript code here

//]]>
</script>

Then everything worked perfectly!

This should work.

class GlobalStore {
    static GlobalStore _instance;
    static GlobalStore get instance {
       if(_instance == null)
           _instance = new GlobalStore()._();
       return _instance;
    }

    _(){

    }
    factory GlobalStore()=> instance;


}

If you have reached here that means all the other solutions did not work for you. One reason could be your source folder is not a java project.

Solution would be to run below command on the source folder

mvn eclipse:eclipse

This worked for me.

If this also doesn't work then try removing .classpath and .project file and run the above command again

$('#comboBx').append($("<option></option>").attr("value",key).text(value));

where comboBx is your combo box id.

or you can append options as string to the already existing innerHTML and then assign to the select innerHTML.

Edit

If you need to keep the first option and remove all other then you can use

var firstOption = $("#cmb1 option:first-child");
$("#cmb1").empty().append(firstOption);

For a JQM+PhoneGap app the following worked for me.

The following was the minimum I had to go to get this to work. I was actually experiencing a stall due to the buffering while spawning ajax requests when the user pressed the back button. Pausing the video in Chrome and the Android browser kept it buffering. The non-async ajax request would get stuck waiting for the buffering to finish, which it never would.

Binding this to the beforepagehide event fixed it.

 $("#SOME_JQM_PAGE").live("pagebeforehide", function(event)
 {
           $("video").each(function () 
           { 
               logger.debug("PAUSE VIDEO");
               this.pause();
               this.src = "";
           });
 });

This will clear every video tag on the page.

The important part is this.src = "";

Microsoft has an article about this issue. It goes through it all step by step.

https://docs.microsoft.com/en-us/sql/database-engine/configure-windows/connect-to-sql-server-when-system-administrators-are-locked-out

In short it involves starting up the instance of sqlserver with -m like all the other answers suggest. However Microsoft provides slightly more detailed instructions.

From the Start page, start SQL Server Management Studio. On the View menu, select Registered Servers. (If your server is not already registered, right-click Local Server Groups, point to Tasks, and then click Register Local Servers.)

In the Registered Servers area, right-click your server, and then click SQL Server Configuration Manager. This should ask for permission to run as administrator, and then open the Configuration Manager program.

Close Management Studio.

In SQL Server Configuration Manager, in the left pane, select SQL Server Services. In the right-pane, find your instance of SQL Server. (The default instance of SQL Server includes (MSSQLSERVER) after the computer name. Named instances appear in upper case with the same name that they have in Registered Servers.) Right-click the instance of SQL Server, and then click Properties.

On the Startup Parameters tab, in the Specify a startup parameter box, type -m and then click Add. (That's a dash then lower case letter m.)

Note

For some earlier versions of SQL Server there is no Startup Parameters tab. In that case, on the Advanced tab, double-click Startup Parameters. The parameters open up in a very small window. Be careful not to change any of the existing parameters. At the very end, add a new parameter ;-m and then click OK. (That's a semi-colon then a dash then lower case letter m.)

Click OK, and after the message to restart, right-click your server name, and then click Restart.

After SQL Server has restarted your server will be in single-user mode. Make sure that that SQL Server Agent is not running. If started, it will take your only connection.

On the Windows 8 start screen, right-click the icon for Management Studio. At the bottom of the screen, select Run as administrator. (This will pass your administrator credentials to SSMS.)

Note

For earlier versions of Windows, the Run as administrator option appears as a sub-menu.

In some configurations, SSMS will attempt to make several connections. Multiple connections will fail because SQL Server is in single-user mode. You can select one of the following actions to perform. Do one of the following.

a) Connect with Object Explorer using Windows Authentication (which includes your Administrator credentials). Expand Security, expand Logins, and double-click your own login. On the Server Roles page, select sysadmin, and then click OK.

b) Instead of connecting with Object Explorer, connect with a Query Window using Windows Authentication (which includes your Administrator credentials). (You can only connect this way if you did not connect with Object Explorer.) Execute code such as the following to add a new Windows Authentication login that is a member of the sysadmin fixed server role. The following example adds a domain user named CONTOSO\PatK.

CREATE LOGIN [CONTOSO\PatK] FROM WINDOWS;   ALTER SERVER ROLE
sysadmin ADD MEMBER [CONTOSO\PatK];   

c) If your SQL Server is running in mixed authentication mode, connect with a Query Window using Windows Authentication (which includes your Administrator credentials). Execute code such as the following to create a new SQL Server Authentication login that is a member of the sysadmin fixed server role.

CREATE LOGIN TempLogin WITH PASSWORD = '************';   ALTER
SERVER ROLE sysadmin ADD MEMBER TempLogin;   

Warning:

Replace ************ with a strong password.

d) If your SQL Server is running in mixed authentication mode and you want to reset the password of the sa account, connect with a Query Window using Windows Authentication (which includes your Administrator credentials). Change the password of the sa account with the following syntax.

ALTER LOGIN sa WITH PASSWORD = '************';   Warning

Replace ************ with a strong password.

The following steps now change SQL Server back to multi-user mode. Close SSMS.

In SQL Server Configuration Manager, in the left pane, select SQL Server Services. In the right-pane, right-click the instance of SQL Server, and then click Properties.

On the Startup Parameters tab, in the Existing parameters box, select -m and then click Remove.

Note

For some earlier versions of SQL Server there is no Startup Parameters tab. In that case, on the Advanced tab, double-click Startup Parameters. The parameters open up in a very small window. Remove the ;-m which you added earlier, and then click OK.

Right-click your server name, and then click Restart.

Now you should be able to connect normally with one of the accounts which is now a member of the sysadmin fixed server role.

Step 1: Go to json.org to find the JSON library for whatever technology you're using to call this web service. Download and link to that library.

Step 2: Let's say you're using Java. You would use JSONArray like this:

JSONArray myArray=new JSONArray(queryResponse);
for (int i=0;i<myArray.length;i++){
    JSONArray myInteriorArray=myArray.getJSONArray(i);
    if (i==0) {
        //this is the first one and is special because it holds the name of the query.
    }else{
        //do your stuff
        String stateCode=myInteriorArray.getString(0);
        String stateName=myInteriorArray.getString(1);
    }
}

The solution is to simply not declare width: 100%.

The default is width: auto, which for block-level elements (such as div), will take the "full space" available anyway (different to how width: 100% does it).

See: http://jsfiddle.net/U7PhY/2/

Just in case it's not already clear from my answer: just don't set a width on the child div.

You might instead be interested in box-sizing: border-box.

The thing you are missing is which encoding scheme is being used. There are different ways to encode binary numbers. Look into signed number representations. For 9 bits, the ranges and the amount of numbers that can be represented will differ depending on the system used.

Are you allowed to use a framework? jQuery and Prototype make this sort of thing pretty easy. Here's a sample in Prototype:

var elem = new Element('img', { 'class': 'foo', src: 'pic.jpg', alt: 'alternate text' });
$(document).insert(elem);

My favorite smtp server is hMailServer.

It has a nice windows friendly installer and wizard. Hands down the easiest mail server I've ever setup.

It can proxy through your gmail/yahoo/etc account or send email directly.

Once it is installed, email in xampp just works with no config changes.

Post uses the message body to send the information back to the server, as opposed to Get, which uses the query string (everything after the question mark). It is possible to send both a Get query string and a Post message body in the same request, but that can get a bit confusing so is best avoided.

Generally, best practice dictates that you use Get when you want to retrieve data, and Post when you want to alter it. (These rules aren't set in stone, the specs don't forbid altering data with Get, but it's generally avoided on the grounds that you don't want people making changes just by clicking a link or typing a URL)

Conversely, you can use Post to retrieve data without changing it, but using Get means you can bookmark the page, or share the URL with other people, things you couldn't do if you'd used Post.

• http://en.wikipedia.org/wiki/GET_%28HTTP%29
• http://en.wikipedia.org/wiki/POST_%28HTTP%29

As for the actual format of the data sent in the message body, that's entirely up to the sender and is specified with the Content-Type header. If not specified, the default content-type for HTML forms is application/x-www-form-urlencoded, which means the server will expect the post body to be a string encoded in a similar manner to a GET query string. However this can't be depended on in all cases. RFC2616 says the following on the Content-Type header:

Any HTTP/1.1 message containing an entity-body SHOULD include a
Content-Type header field defining the media type of that body. If
and only if the media type is not given by a Content-Type field, the
recipient MAY attempt to guess the media type via inspection of its
content and/or the name extension(s) of the URI used to identify the
resource. If the media type remains unknown, the recipient SHOULD
treat it as type "application/octet-stream".

Use wildcards:

cp /home/ankur/folder/* /home/ankur/dest

If you don't want to copy all the files, you can use braces to select files:

cp /home/ankur/folder/{file{1,2},xyz,abc} /home/ankur/dest

This will copy file1, file2, xyz, and abc.

You should read the sections of the bash man page on Brace Expansion and Pathname Expansion for all the ways you can simplify this.

Another thing you can do is cd /home/ankur/folder. Then you can type just the filenames rather than the full pathnames, and you can use filename completion by typing Tab.

If you're like me and you just want to do path-based lookups, but don't care about real XPath, lodash's _.get() can work. Example from lodash docs:

var object = { 'a': [{ 'b': { 'c': 3 } }] };

_.get(object, 'a[0].b.c');
// ? 3

_.get(object, ['a', '0', 'b', 'c']);
// ? 3

_.get(object, 'a.b.c', 'default');
// ? 'default'

2020 UPDATE:

Converting HTML to PDF is very simple to do now. All you have to do is use NuGet to install itext7 and itext7.pdfhtml. You can do this in Visual Studio by going to "Project" > "Manage NuGet Packages..."

Make sure to include this dependency:

using iText.Html2pdf;

Now literally just paste this one liner and you're done:

HtmlConverter.ConvertToPdf(new FileInfo(@"temp.html"), new FileInfo(@"report.pdf"));

If you're running this example in visual studio, your html file should be in the /bin/Debug directory.

If you're interested, here's a good resource. Also, note that itext7 is licensed under AGPL.

With the package pROC you can use the function auc() like this example from the help page:

> data(aSAH)
> 
> # Syntax (response, predictor):
> auc(aSAH$outcome, aSAH$s100b)
Area under the curve: 0.7314

You guys don't need those complex things to set locales on Ubuntu/Debian. You don't even need /etc/local.gen file.

Simply locale-gen will do everything and the author only missed locales package.

RUN apt-get update && apt-get install -y locales && rm -rf /var/lib/apt/lists/* \
 && locale-gen "en_US.UTF-8"
ENV LANG=en_US.UTF-8 \
    LANGUAGE=en_US:en \
    LC_ALL=en_US.UTF-8

I found this the simplest and the most effective. I confirm it works on Ubuntu 16.04.

since you only want the files, you don't need to treat it as a git repo.

rsync -rlp --exclude '.git' user@host:path/to/git/repo/ .

and this only works with local path and remote ssh/rsync path, it may not work if the remote server only provides git:// or https:// access.
