Updated answer that covers most cases

curl -H "Access-Control-Request-Method: GET" -H "Origin: http://localhost" --head http://www.example.com/

1. Replace http://www.example.com/ with URL you want to test.
2. If response includes Access-Control-Allow-* then your resource supports CORS.

Rationale for alternative answer

I google this question every now and then and the accepted answer is never what I need. First it prints response body which is a lot of text. Adding --head outputs only headers. Second when testing S3 URLs we need to provide additional header -H "Access-Control-Request-Method: GET".

Hope this will save time.

Use requests module:

import requests

myip = requests.get('https://www.wikipedia.org').headers['X-Client-IP']

print("\n[+] Public IP: "+myip)

As drew_w said, you can find a good example here.

JSFIDDLE

For those running Laravel Mix with npm run watch, just terminate the script and run the command again.

Using ~* can improve greatly on performance, with functionality of INSTR.

SELECT id FROM groups WHERE name ~* 'adm'

return rows with name that contains OR equals to 'adm'.

This solution comes from my personal experience. We used several Amazon S3 buckets and one server for redirecting non-www to www domain names to match S3 "Host" header policy.

I used the following configuration for nginx server:

server {
    listen 80;
    server_name ~^(?!www\.)(?<domain>.+)$;
    return 301 $scheme://www.$domain$request_uri;
}

This matches all domain names pointed to the server starting with whatever but www. and redirects to www.<domain>. In the same manner you can do opposite redirect from www to non-www.

I wrote a simple class to build a confusion matrix without the need to depend on a machine learning library.

The class can be used such as:

labels = ["cat", "dog", "velociraptor", "kraken", "pony"]
confusionMatrix = ConfusionMatrix(labels)

confusionMatrix.update("cat", "cat")
confusionMatrix.update("cat", "dog")
...
confusionMatrix.update("kraken", "velociraptor")
confusionMatrix.update("velociraptor", "velociraptor")

confusionMatrix.plot()

The class ConfusionMatrix:

import pylab
import collections
import numpy as np


class ConfusionMatrix:
    def __init__(self, labels):
        self.labels = labels
        self.confusion_dictionary = self.build_confusion_dictionary(labels)

    def update(self, predicted_label, expected_label):
        self.confusion_dictionary[expected_label][predicted_label] += 1

    def build_confusion_dictionary(self, label_set):
        expected_labels = collections.OrderedDict()

        for expected_label in label_set:
            expected_labels[expected_label] = collections.OrderedDict()

            for predicted_label in label_set:
                expected_labels[expected_label][predicted_label] = 0.0

        return expected_labels

    def convert_to_matrix(self, dictionary):
        length = len(dictionary)
        confusion_dictionary = np.zeros((length, length))

        i = 0
        for row in dictionary:
            j = 0
            for column in dictionary:
                confusion_dictionary[i][j] = dictionary[row][column]
                j += 1
            i += 1

        return confusion_dictionary

    def get_confusion_matrix(self):
        matrix = self.convert_to_matrix(self.confusion_dictionary)
        return self.normalize(matrix)

    def normalize(self, matrix):
        amin = np.amin(matrix)
        amax = np.amax(matrix)

        return [[(((y - amin) * (1 - 0)) / (amax - amin)) for y in x] for x in matrix]

    def plot(self):
        matrix = self.get_confusion_matrix()

        pylab.figure()
        pylab.imshow(matrix, interpolation='nearest', cmap=pylab.cm.jet)
        pylab.title("Confusion Matrix")

            for j, vj in enumerate(vi):
                pylab.text(j, i+.1, "%.1f" % vj, fontsize=12)

        pylab.colorbar()

        classes = np.arange(len(self.labels))
        pylab.xticks(classes, self.labels)
        pylab.yticks(classes, self.labels)

        pylab.ylabel('Expected label')
        pylab.xlabel('Predicted label')
        pylab.show()

Or, just add your binary path into the PATH. At the end of the bashrc:

... 
export PATH=$PATH:/home/user/.local/bin/

save the file and run:

source .bashrc

and the command will work.

A). I never have and never will trust any tool which purports to produce code without the user coding, which goes double where it's a graphical tool.

B). I've never had any problem with this with Facebook Connect. It's all still plain old JavaScript code running in a browser and undefined===undefined wherever you are.

In short, you need to provide evidence that your object.x really really was undefined and not null or otherwise, because I believe it is impossible for what you're describing to actually be the case - no offence :) - I'd put money on the problem existing in the Tersus code.

SchemaCrawler for PostgreSQL can generate database diagrams from the command line, with the help of GraphViz. You can use regular expressions to include and exclude tables and columns. It can also infer relationships between tables using common naming conventions, if not foreign keys are defined.

If I understand correctly, you want to see not only classes but also methods, properties and so on. The only tool I know that can do it is Eclipse - if you add a jar to project classpath, you would be able to browse its classes with methods and properties using usual package explorer.

Anyway, this is a good idea for a good standalone Java tool

Sometimes it is the simple things. In my case, I had an invalid url. I had left out a colon before the at sign (@). I had "jdbc:oracle:thin@//localhost" instead of "jdbc:oracle:thin:@//localhost" Hope this helps someone else with this issue.

I had the same problem and what I did is to replace the single quotes with the double one, but what was worse is the fact I had the same error when I had a comma for the last attribute of the json object. So I used regex in python to replace it before using the json.loads() function. (Be careful about the s at the end of "loads")

import re

with open("file.json", 'r') as f:
     s = f.read()
     correct_format = re.sub(", *\n *}", "}", s)
     data_json = json.loads(correct_format)

The used regex return each comma followed by a newline and "}", replacing it just with a "}".

This should work i did the following for a game server project. It will download the zip and extract it to what ever directory you specify.

After reading Misko's articles I believe that static methods are bad from a testing point of view. You should have factories instead(maybe using a dependency injection tool like Guice).

how do I ensure that I only have one of something

only have one of something The problem of “how do I ensure that I only have one of something” is nicely sidestepped. You instantiate only a single ApplicationFactory in your main, and as a result, you only instantiate a single instance of all of your singletons.

The basic issue with static methods is they are procedural code

The basic issue with static methods is they are procedural code. I have no idea how to unit-test procedural code. Unit-testing assumes that I can instantiate a piece of my application in isolation. During the instantiation I wire the dependencies with mocks/friendlies which replace the real dependencies. With procedural programing there is nothing to "wire" since there are no objects, the code and data are separate.

A formula to return either the first word or all the other words.

=IF(ISERROR(FIND(" ",TRIM(A2),1)),TRIM(A2),MID(TRIM(A2),FIND(" ",TRIM(A2),1),LEN(A2)))

Examples and results

Text                  Description                      Results

                      Blank 
                      Space 
some                  Text no space                some
some text             Text with space                  text
 some                 Text with leading space          some
some                  Text with trailing space         some
some text some text   Text with multiple spaces        text some text

Comments on Formula:

• The TRIM function is used to remove all leading and trailing spaces. Duplicate spacing within the text is also removed.
• The FIND function then finds the first space
• If there is no space then the trimmed text is returned
• Otherwise the MID function is used to return any text after the first space

getchar() reads a single character of input and returns that character as the value of the function. If there is an error reading the character, or if the end of input is reached, getchar() returns a special value, represented by EOF.

git rebase -i HEAD^^^

Now mark the ones you want to amend with edit or e (replace pick). Now save and exit.

Now make your changes, then

git add .
git rebase --continue

If you want to add an extra delete remove the options from the commit command. If you want to adjust the message, omit just the --no-edit option.

I think you already solved this problem, and as other answers suggested

android:background="@drawable/eye"

is available. But I prefer

android:src="@drawable/eye"
android:background="00000000" // transparent

and it works well too.(of course former code will set image as a background and the other will set image as a image) But according to your selected answer, I guess you meant 9-patch.

Another PowerShell Solution...

This is not about running a batch script as admin per, but rather how to elevate another program from batch...

I have a batch file "wrapper" for an exe. They have the same "root file name", but alternate extensions. I am able to launch the exe as admin, and set the working directory to the one containing the script, with the following one line powershell invocation:

@powershell "Start-Process -FilePath '%~n0.exe' -WorkingDirectory '%~dp0' -Verb RunAs"

More info

There are a whole slew of additional Start-Process options as well that you can apply! Check out: https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.management/start-process?view=powershell-6

Note that I use the @ prefix. That's equivalent to @echo off for the one line. I use %~n0 here to get the "root name" of the batch script, then I concatenate the .exe to point it the adjancent binary. The use of %~dp0 provides the full path to the directory which the batch resides. And, of course, the -Verb RunAs parameter provides the elevation.

You could also check my md5 implementation. It should be approx. the same as the other posted above. Unfortunately, the performance is limited by the inner loop which is impossible to optimize more.

Fetch vs Pull

Git fetch just updates your repo data, but a git pull will basically perform a fetch and then merge the branch pulled

What is the difference between 'git pull' and 'git fetch'?

Merge vs Rebase

from Atlassian SourceTree Blog, Merge or Rebase:

Merging brings two lines of development together while preserving the ancestry of each commit history.

In contrast, rebasing unifies the lines of development by re-writing changes from the source branch so that they appear as children of the destination branch – effectively pretending that those commits were written on top of the destination branch all along.

Also, check out Learn Git Branching, which is a nice game that has just been posted to HackerNews (link to post) and teaches a lot of branching and merging tricks. I believe it will be very helpful in this matter.

If you need to respond to changes, you can try this:

document.getElementById('select-meal-type').addEventListener('change', function(e) {
    let values = [].slice.call(e.target.selectedOptions).map(a => a.value));
})

The [].slice.call(e.target.selectedOptions) is needed because e.target.selectedOptions returns a HTMLCollection, not an Array. That call converts it to Array so that we can then apply the map function, which extract the values.

Simple plot,

you can use:

df.plot(x='Date',y='adj_close')

Or you can set the index to be Date beforehand, then it's easy to plot the column you want:

df.set_index('Date', inplace=True)
df['adj_close'].plot()

If you want a chart with one series by ticker on it

You need to groupby before:

df.set_index('Date', inplace=True)
df.groupby('ticker')['adj_close'].plot(legend=True)

If you want a chart with individual subplots:

grouped = df.groupby('ticker')

ncols=2
nrows = int(np.ceil(grouped.ngroups/ncols))

fig, axes = plt.subplots(nrows=nrows, ncols=ncols, figsize=(12,4), sharey=True)

for (key, ax) in zip(grouped.groups.keys(), axes.flatten()):
    grouped.get_group(key).plot(ax=ax)

ax.legend()
plt.show()

Just create a new branch with git checkout -b ABC_1; your uncommitted changes will be kept, and you then commit them to that branch.

Using .net core jwt packages, the Claims are available:

[Route("api/[controller]")]
[ApiController]
[Authorize(Policy = "Bearer")]
public class AbstractController: ControllerBase
{
    protected string UserId()
    {
        var principal = HttpContext.User;
        if (principal?.Claims != null)
        {
            foreach (var claim in principal.Claims)
            {
               log.Debug($"CLAIM TYPE: {claim.Type}; CLAIM VALUE: {claim.Value}");
            }

        }
        return principal?.Claims?.SingleOrDefault(p => p.Type == "username")?.Value;
    }
}

First point is- showing multiple popups is not desirable in terms of usability.

But you can achieve it by using multiple popup names

var newwindow;
function createPop(url, name)
{    
   newwindow=window.open(url,name,'width=560,height=340,toolbar=0,menubar=0,location=0');  
   if (window.focus) {newwindow.focus()}
}

Better approach will be showing both in a single page in two different iFrames or Divs.

Update:

So I will suggest to create a new tab in the test.aspx page to show the report, instead of replacing the image content and placing the pdf.

Just use File.GetLastWriteTime. There's a sample on that page showing how to use it.

Make sure that you have installed the correct NuGet package in your console application:

<package id="Microsoft.AspNet.WebApi.Client" version="4.0.20710.0" />

and that you are targeting at least .NET 4.0.

This being said, your GetAllFoos function is defined to return an IEnumerable<Prospect> whereas in your ReadAsAsync method you are passing IEnumerable<Foo> which obviously are not compatible types.

Install-Package Microsoft.AspNet.WebApi.Client

Using parameter --force:

npm i -f

Beans.xml or file.XML is not placed under proper path. You should add the XML file under the resource folder, if you have a Maven project. src -> main -> java -> resources

y my case i solved this by named it in the "Identifier" property of Table View Cell:

Don't forgot: to declare in your Class: UITableViewDataSource

 let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as UITableViewCell

Check the following snippet for your problem

div{_x000D_
  width : 100px;_x000D_
  overflow:hidden;_x000D_
  display:inline-block;_x000D_
  text-overflow: ellipsis;_x000D_
  white-space: nowrap;_x000D_
}

Consecutive string literals are joined by the compiler, and parenthesized expressions are considered to be a single line of code:

logger.info("Skipping {0} because it's thumbnail was "
  "already in our system as {1}.".format(line[indexes['url']],
  video.title))

To further explain Sheena's answer, I needed to have setup-tools installed as a dependency of another tool e.g. more-itertools.

Download

Click the Clone or download button and choose your method. I placed these into a dev/py/libs directory in my user home directory. It does not matter where they are saved, because they will not be installed there.

• setuptools: https://github.com/pypa/setuptools
• more-itertools: https://github.com/erikrose/more-itertools

Installing setup-tools

You will need to run the following inside the setup-tools directory.

python bootstrap.py
python setup.py install

General dependencies installation

Now you can navigate to the more-itertools direcotry and install it as normal.

1. Download the package
2. Unpackage it if it's an archive
3. Navigate (cd ...) into the directory containing setup.py
4. If there are any installation instructions contained in the documentation contained herein, read and follow the instructions OTHERWISE
5. Type in: python setup.py install

Just note to anyone trying the REGEXP to use "LIKE IN" functionality.

IN allows you to do:

field IN (
'val1',
'val2',
'val3'
)

In REGEXP this won't work

REGEXP '
val1$|
val2$|
val3$
'

It has to be in one line like this:

REGEXP 'val1$|val2$|val3$'

Digging StackOverflow for answers on the similar issue I found people usually suggesting 2 approaches:

• Load a drawable into memory and compare ConstantState or bitmap itself to other one.
• Set a tag with drawable id into a view and compare tags when you need that.

Personally, I like the second approach for performance reason but tagging bunch of views with appropriate tags is painful and time consuming. This could be very frustrating in a big project. In my case I need to write a lot of Espresso tests which require comparing TextView drawables, ImageView resources, View background and foreground. A lot of work.

So I eventually came up with a solution to delegate a 'dirty' work to the custom inflater. In every inflated view I search for a specific attributes and and set a tag to the view with a resource id if any is found. This approach is pretty much the same guys from Calligraphy used. I wrote a simple library for that: TagView

If you use it, you can retrieve any of predefined tags, containing drawable resource id that was set in xml layout file:

TagViewUtils.getTag(view, ViewTag.IMAGEVIEW_SRC.id)
TagViewUtils.getTag(view, ViewTag.TEXTVIEW_DRAWABLE_LEFT.id)
TagViewUtils.getTag(view, ViewTag.TEXTVIEW_DRAWABLE_TOP.id)
TagViewUtils.getTag(view, ViewTag.TEXTVIEW_DRAWABLE_RIGHT.id)
TagViewUtils.getTag(view, ViewTag.TEXTVIEW_DRAWABLE_BOTTOM.id)
TagViewUtils.getTag(view, ViewTag.VIEW_BACKGROUND.id)
TagViewUtils.getTag(view, ViewTag.VIEW_FOREGROUND.id)

The library supports any attribute, actually. You can add them manually, just look into the Custom attributes section on Github. If you set a drawable in runtime you can use convenient library methods:

setImageViewResource(ImageView view, int id)

In this case tagging is done for you internally. If you use Kotlin you can write a handy extensions to call view itself. Something like this:

fun ImageView.setImageResourceWithTag(@DrawableRes int id) {
    TagViewUtils.setImageViewResource(this, id)
}

You can find additional info in Tagging in runtime

I don't yet have the rep needed to add a comment or I would have just added this to Bell's answer. I think Bell did a very good job of summing up the top level pros and cons of the two approaches. Just a few other factors that you might want to consider:

1) Do the requests between your clients and your service need to go through intermediaries that require access to the payload? If so then WS-Security might be a better fit.

2) It is actually possible to use SSL to provide the server with assurance as to the clients identity using a feature called mutual authentication. However, this doesn't get much use outside of some very specialized scenarios due to the complexity of configuring it. So Bell is right that WS-Sec is a much better fit here.

3) SSL in general can be a bit of a bear to setup and maintain (even in the simpler configuration) due largely to certificate management issues. Having someone who knows how to do this for your platform will be a big plus.

4) If you might need to do some form of credential mapping or identity federation then WS-Sec might be worth the overhead. Not that you can't do this with REST, you just have less structure to help you.

5) Getting all the WS-Security goop into the right places on the client side of things can be more of a pain than you would think it should.

In the end though it really does depend on a lot of things we're not likely to know. For most situations I would say that either approach will be "secure enough" and so that shouldn't be the main deciding factor.

str.lower() converts all cased characters to lowercase.

The simplest way for me is to use ILSpy.

When you drag & drop the assembly on its window and select the dropped assembly on the the left, you can see the public key token on the right side of the window.

(I also think that the newer versions will also display the public key of the signature, if you ever need that one... See here: https://github.com/icsharpcode/ILSpy/issues/610#issuecomment-111189234. Good stuff! ;))

I really miss that feature. Only way to achieve something similar is to use functions.

I have used it in two ways:

• perl functions that use $_SHARED variable
• store your variables in table

Perl version:

   CREATE FUNCTION var(name text, val text) RETURNS void AS $$
        $_SHARED{$_[0]} = $_[1];
   $$ LANGUAGE plperl;
   CREATE FUNCTION var(name text) RETURNS text AS $$
        return $_SHARED{$_[0]};
   $$ LANGUAGE plperl;

Table version:

CREATE TABLE var (
  sess bigint NOT NULL,
  key varchar NOT NULL,
  val varchar,
  CONSTRAINT var_pkey PRIMARY KEY (sess, key)
);
CREATE FUNCTION var(key varchar, val anyelement) RETURNS void AS $$
  DELETE FROM var WHERE sess = pg_backend_pid() AND key = $1;
  INSERT INTO var (sess, key, val) VALUES (sessid(), $1, $2::varchar);
$$ LANGUAGE 'sql';

CREATE FUNCTION var(varname varchar) RETURNS varchar AS $$
  SELECT val FROM var WHERE sess = pg_backend_pid() AND key = $1;
$$ LANGUAGE 'sql';

Notes:

• plperlu is faster than perl
• pg_backend_pid is not best session identification, consider using pid combined with backend_start from pg_stat_activity
• this table version is also bad because you have to clear this is up occasionally (and not delete currently working session variables)

The current answers are fine and should work ok, but what's wrong with the more simple, more obvious, and more maintainable:

IF @flag = 1
    UPDATE table_name SET column_A = column_A + @new_value WHERE ID = @ID;
ELSE
    UPDATE table_name SET column_B = column_B + @new_value WHERE ID = @ID;

This is much easier to read albeit this is a very simple query.

Here's a working example courtesy of @snyder: SqlFiddle.

You could import the System.IO namespace using:

using System.IO;

If the filepath represents the full path to the file, you can check its existence and delete it as follows:

if(File.Exists(filepath))
{
     try
    {
         File.Delete(filepath);
    } 
    catch(Exception ex)
    {
      //Do something
    } 
}  

You may need to call conn.recv() multiple times to receive all the data. Calling it a single time is not guaranteed to bring in all the data that was sent, due to the fact that TCP streams don't maintain frame boundaries (i.e. they only work as a stream of raw bytes, not a structured stream of messages).

See this answer for another description of the issue.

Note that this means you need some way of knowing when you have received all of the data. If the sender will always send exactly 8000 bytes, you could count the number of bytes you have received so far and subtract that from 8000 to know how many are left to receive; if the data is variable-sized, there are various other methods that can be used, such as having the sender send a number-of-bytes header before sending the message, or if it's ASCII text that is being sent you could look for a newline or NUL character.

Based on the title of this question, I came here wanting to convert a String into an array of substrings divided by some delimiter. I will add that answer here for others who may have the same question.

This makes an array of words by splitting the string at every space:

String str = "string to string array conversion in java";
String delimiter = " ";
String strArray[] = str.split(delimiter);

This creates the following array:

// [string, to, string, array, conversion, in, java]

Tested in Java 8

Use modern JavaScript!

I'd suggest looking into fetch. It is the ES5 equivalent and uses Promises. It is much more readable and easily customizable.

const url = "http://example.com";
fetch(url, {
    method : "POST",
    body: new FormData(document.getElementById("inputform")),
    // -- or --
    // body : JSON.stringify({
        // user : document.getElementById('user').value,
        // ...
    // })
}).then(
    response => response.text() // .json(), etc.
    // same as function(response) {return response.text();}
).then(
    html => console.log(html)
);

In Node.js, you'll need to import fetch using:

const fetch = require("node-fetch");

If you want to use it synchronously (doesn't work in top scope):

const json = await fetch(url, optionalOptions)
  .then(response => response.json()) // .text(), etc.
  .catch((e) => {});

Look in the file Microsoft.Common.targets

The answer to the question is in the file Microsoft.Common.targets for your target framework version.

For .Net Framework version 4.0 (and 4.5 !) the AssemblySearchPaths-element is defined like this:

    <!--
    The SearchPaths property is set to find assemblies in the following order:

        (1) Files from current project - indicated by {CandidateAssemblyFiles}
        (2) $(ReferencePath) - the reference path property, which comes from the .USER file.
        (3) The hintpath from the referenced item itself, indicated by {HintPathFromItem}.
        (4) The directory of MSBuild's "target" runtime from GetFrameworkPath.
            The "target" runtime folder is the folder of the runtime that MSBuild is a part of.
        (5) Registered assembly folders, indicated by {Registry:*,*,*}
        (6) Legacy registered assembly folders, indicated by {AssemblyFolders}
        (7) Resolve to the GAC.
        (8) Treat the reference's Include as if it were a real file name.
        (9) Look in the application's output folder (like bin\debug)
    -->
<AssemblySearchPaths Condition=" '$(AssemblySearchPaths)' == ''">
  {CandidateAssemblyFiles};
  $(ReferencePath);
  {HintPathFromItem};
  {TargetFrameworkDirectory};
  {Registry:$(FrameworkRegistryBase),$(TargetFrameworkVersion),$(AssemblyFoldersSuffix)$(AssemblyFoldersExConditions)};
  {AssemblyFolders};
  {GAC};
  {RawFileName};
  $(OutDir)
</AssemblySearchPaths>

For .Net Framework 3.5 the definition is the same, but the comment is wrong. The 2.0 definition is slightly different, it uses $(OutputPath) instead of $(OutDir).

On my machine I have the following versions of the file Microsoft.Common.targets:

C:\Windows\Microsoft.NET\Framework\v2.0.50727\Microsoft.Common.targets
C:\Windows\Microsoft.NET\Framework\v3.5\Microsoft.Common.targets
C:\Windows\Microsoft.NET\Framework\v4.0.30319\Microsoft.Common.targets

C:\Windows\Microsoft.NET\Framework64\v2.0.50727\Microsoft.Common.targets
C:\Windows\Microsoft.NET\Framework64\v3.5\Microsoft.Common.targets
C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Microsoft.Common.targets

This is with Visual Studio 2008, 2010 and 2013 installed on Windows 7.

The fact that the output directory is searched can be a bit frustrating (as the original poster points out) because it may hide an incorrect HintPath. The solution builds OK on your local machine, but breaks when you build on in a clean folder structure (e.g. on the build machine).

It should be CascadeType.Merge, in that case it will update if the record already exists.

Kotlin versions

When you are on an activity, then use

runOnUiThread {
    //code that runs in main
}

When you have activity context, mContext then use

mContext.runOnUiThread {
    //code that runs in main
}

When you are in somewhere where no context available, then use

Handler(Looper.getMainLooper()).post {  
    //code that runs in main
}

In Swift 3.0

let number:NSNumber = 25
let strValue = String(describing: number as NSNumber)
print("As String => \(strValue)")

We can get the number value in String.

Also, be aware of differences in casting, especially when working with bitmasks, due to casting to signed char:

bool a = 0x0100;
a == true;  // expression true

BOOL b = 0x0100;
b == false; // expression true on !((TARGET_OS_IPHONE && __LP64__) || TARGET_OS_WATCH), e.g. MacOS
b == true;  // expression true on (TARGET_OS_IPHONE && __LP64__) || TARGET_OS_WATCH

If BOOL is a signed char instead of a bool, the cast of 0x0100 to BOOL simply drops the set bit, and the resulting value is 0.

This Question was asked here: VBA Arrays - Check strict (not approximative) match

Sub test()
    vars1 = Array("Examples")
    vars2 = Array("Example")
    If IsInArray(Range("A1").value, vars1) Then
        x = 1
    End If

    If IsInArray(Range("A1").value, vars2) Then
        x = 1
    End If
End Sub

Function IsInArray(stringToBeFound As String, arr As Variant) As Boolean
    IsInArray = Not IsError(Application.Match(stringToBeFound, arr, 0))
End Function

In Swift 3, you can simply use CGPoint.zero or CGRect.zero in place of CGRectZero or CGPointZero.

However, in Swift 4, CGRect.zero and 'CGPoint.zero' will work

Try

isSubstring = first in theOther

I too had this problem when i was trying out Gelocation API. I then started IIS express through visual studio and then accessed the page and It worked without any issue in all browsers.

It is not required for me to use the PDFBox library, so a solution that uses another library is fine

Camelot and Excalibur

You may want to try Python library Camelot, an open source library for Python. If you are not inclined to write code, you may use the web interface Excalibur created around Camelot. You "upload" the document to a localhost web server, and "download" the result from this localhost server.

Here is an example from using this python code:

import camelot
tables = camelot.read_pdf('foo.pdf', flavor="stream")
tables[0].to_csv('foo.csv')

The input is a pdf containing this table:

^{Sample table from the PDF-TREX set}

No help is provided to camelot, it is working on its own by looking at pieces of text relative alignment. The result is returned in a csv file:

^{PDF table extracted from sample by camelot}

"Rules" can de added to help camelot identify where are fillets in sophisticated tables:

^{Rule added in Excalibur. Source}

GitHub:

• Camelot: https://github.com/camelot-dev/camelot
• Excalibur: https://github.com/camelot-dev/excalibur

The two projects are active.

Here is a comparison with other software (with test based on actual documents), Tabula, pdfplumber, pdftables, pdf-table-extract.

I want is to be able to parse the file and know what each parsed number means

You cannot do that automatically, as pdf is not semantically structured.

Book versus document

Pdf "documents" are unstructured from a semantic standpoint (it's like a notepad file), the pdf document gives instructions on where to print a text fragment, unrelated to other fragments of the same section, there is no separation between content (what to print, and whether this is a fragment of a title, a table or a footnote) and the visual representation (font, location, etc). Pdf is an extension of PostScript, which describes a Hello world! page this way:

!PS
 /Courier             % font
 20 selectfont        % size
 72 500 moveto        % current location to print at
 (Hello world!) show  % add text fragment
 showpage             % print all on the page

(Wikipedia).
One can imagine what a table looks like with the same instructions.

We could say html is not clearer, however there is a big difference: Html describes the content semantically (title, paragraph, list, table header, table cell, ...) and associates the css to produce a visual form, hence content is fully accessible. In this sense, html is a simplified descendant of sgml which puts constraints to allow data processing:

Markup should describe a document's structure and other attributes rather than specify the processing that needs to be performed, because it is less likely to conflict with future developments.

exactly the opposite of PostScript/Pdf. SGML is used in publishing. Pdf doesn't embed this semantical structure, it carries only the css-equivalent associated to plain character strings which may not be complete words or sentences. Pdf is used for closed documents and now for the so-called workflow management.

After having experimented the uncertainty and difficulty in trying to extract data from pdf, it's clear pdf is not at all a solution to preserve a document content for the future (in spite Adobe has obtained from their pairs a pdf standard).

What is actually preserved well is the printed representation, as the pdf was fully dedicated to this aspect when created. Pdf are nearly as dead as printed books.

When reusing the content matters, one must rely again on manual re-entering of data, like from a printed book (possibly trying to do some OCR on it). This is more and more true, as many pdf even prevent the use of copy-paste, introducing multiple spaces between words or produce an unordered characters gibberish when some "optimization" is done for web use.

When the content of the document, not its printed representation, is valuable, then pdf is not the correct format. Even Adobe is unable to recreate perfectly the source of a document from its pdf rendering.

So open data should never be released in pdf format, this limits their use to reading and printing (when allowed), and makes reuse harder or impossible.

why not select active tab first then active the selected tab content ?
1. Add class 'active' to the < li > element of tab first .
2. then use set 'active' class to selected div.

    $(document).ready( function(){
        SelectTab(1); //or use other method  to set active class to tab
        ShowInitialTabContent();

    });
    function SelectTab(tabindex)
    {
        $('.nav-tabs li ').removeClass('active');
        $('.nav-tabs li').eq(tabindex).addClass('active'); 
        //tabindex start at 0 
    }
    function FindActiveDiv()
    {  
        var DivName = $('.nav-tabs .active a').attr('href');  
        return DivName;
    }
    function RemoveFocusNonActive()
    {
        $('.nav-tabs  a').not('.active').blur();  
        //to >  remove  :hover :focus;
    }
    function ShowInitialTabContent()
    {
        RemoveFocusNonActive();
        var DivName = FindActiveDiv();
        if (DivName)
        {
            $(DivName).addClass('active'); 
        } 
    }

You can also add the toolbar in Visual Studio to have the buttons available.

View > Toolbars > Text Editor

You need to define width of the div containing the textarea and when you declare textarea, you can then set .main > textarea to have width: inherit.

Note: .main > textarea means a <textarea> inside of an element with class="main".

Here is the working solution

The HTML:

<div class="wrapper">
  <div class="left">left</div>
  <div class="main">
    <textarea name="" cols="" rows=""></textarea>
  </div>
</div>

The CSS:

.wrapper {
  display: table;
  width: 100%;
}

.left {
  width: 20%;
  background: #cccccc;
  display: table-cell;
}

.main {
  width: 80%;
  background: gray;
  display: inline;
}

.main > textarea {
  width: inherit;
}

It's a design pattern and it's not specific to c#. More about it all over the internet and SO, like on this wikipedia article.

In software engineering, the singleton pattern is a design pattern that is used to restrict instantiation of a class to one object. This is useful when exactly one object is needed to coordinate actions across the system. The concept is sometimes generalized to systems that operate more efficiently when only one object exists, or that restrict the instantiation to a certain number of objects (say, five). Some consider it an anti-pattern, judging that it is overused, introduces unnecessary limitations in situations where a sole instance of a class is not actually required, and introduces global state into an application.

You should use it if you want a class that can only be instanciated once.

Apparently, your class "Format" is involved in the problem. Check your declaration of this class, especially if you did it inside another class you probably forgot the @implementation or something similar.

Some of the links provided are only settings for Windows 2003's version of "Scheduled Tasks"

In Windows Server 2008 the "Tasks" setup only has a box with options for "5 Minutes, 10 minutes, 15 minutes, 30 mins, and 1 hour" (screen shot: http://i46.tinypic.com/2gwx7r8.jpg)... where the Window 2003 was a "enter whatever number you want" textbox.

I thought doing an "Export" and editing the XML from: PT30M to PT2M

and importing that as a new task would "trick" Tasks into repeating every 2 mins, but it didn't like that

My workaround for getting a task to run every 2 mins in Windows 2008 was to (ugggh) setup 30 different "triggers" for my task repeating every hour but staring at :00, :02, :04, :06 and so on and so on.... took me 8-10 mins to setup but I only had to do it once :-)

For Bootstrap 4 I find the following very handy because:

• the column on the right takes exactly the space it needs and will pull right
• while the left col always gets the maximum amount of space!.

It is the combination of col and col-auto which does the magic. So you don't have to define a col width (like col-2,...)

<div class="row">
    <div class="col">Left</div>
    <div class="col-auto">Right</div>
</div>

Ideal for aligning words, icons, buttons,... to the right.

An example to have this responsive on small devices:

<div class="row">
    <div class="col">Left</div>
    <div class="col-12 col-sm-auto">Right (Left on small)</div>
</div>

Check this Fiddle https://jsfiddle.net/Julesezaar/tx08zveL/

You can check it with utility method "isEmpty" from TextUtils,

isEmpty(CharSequence str) method check both condition, for null and length.

public static boolean isEmpty(CharSequence str) {
     if (str == null || str.length() == 0)
        return true;
     else
        return false;
}

I was looking for a inline editing solution and I found a plunker that seemed promising, but it didn't work for me out of the box. After some tinkering with the code I got it working. Kudos to the person who made the initial effort to code this piece.

The example is available here http://plnkr.co/edit/EsW7mV?p=preview

Here goes the code:

app.controller('MainCtrl', function($scope) {

  $scope.updateTodo = function(indx) {
    console.log(indx);
  };

  $scope.cancelEdit = function(value) {
    console.log('Canceled editing', value);
  };

  $scope.todos = [
    {id:123, title: 'Lord of the things'},
    {id:321, title: 'Hoovering heights'},
    {id:231, title: 'Watership brown'}
  ];
});

// On esc event
app.directive('onEsc', function() {
  return function(scope, elm, attr) {
    elm.bind('keydown', function(e) {
      if (e.keyCode === 27) {
        scope.$apply(attr.onEsc);
      }
    });
  };
});

// On enter event
app.directive('onEnter', function() {
  return function(scope, elm, attr) {
    elm.bind('keypress', function(e) {
      if (e.keyCode === 13) {
        scope.$apply(attr.onEnter);
      }
    });
  };
});

// Inline edit directive
app.directive('inlineEdit', function($timeout) {
  return {
    scope: {
      model: '=inlineEdit',
      handleSave: '&onSave',
      handleCancel: '&onCancel'
    },
    link: function(scope, elm, attr) {
      var previousValue;

      scope.edit = function() {
        scope.editMode = true;
        previousValue = scope.model;

        $timeout(function() {
          elm.find('input')[0].focus();
        }, 0, false);
      };
      scope.save = function() {
        scope.editMode = false;
        scope.handleSave({value: scope.model});
      };
      scope.cancel = function() {
        scope.editMode = false;
        scope.model = previousValue;
        scope.handleCancel({value: scope.model});
      };
    },
    templateUrl: 'inline-edit.html'
  };
});

Directive template:

<div>
  <input type="text" on-enter="save()" on-esc="cancel()" ng-model="model" ng-show="editMode">
  <button ng-click="cancel()" ng-show="editMode">cancel</button>
  <button ng-click="save()" ng-show="editMode">save</button>
  <span ng-mouseenter="showEdit = true" ng-mouseleave="showEdit = false">
    <span ng-hide="editMode" ng-click="edit()">{{model}}</span>
    <a ng-show="showEdit" ng-click="edit()">edit</a>
  </span>
</div>

To use it just add water:

<div ng-repeat="todo in todos" 
     inline-edit="todo.title" 
     on-save="updateTodo($index)" 
     on-cancel="cancelEdit(todo.title)"></div>

UPDATE:

Another option is to use the readymade Xeditable for AngularJS:

http://vitalets.github.io/angular-xeditable/

You can use Oracle.ManagedDataAccess.dll instead (download from Oracle), include that dll in you project bin dir, add reference to that dll in the project. In code, "using Oracle.MangedDataAccess.Client". Deploy project to server as usual. No need install Oracle Client on server. No need to add assembly info in web.config.

Thanks for this thread -- it helped me a lot too.

I learned something about .join() today.

These threads run in parallel:

d.start()
t.start()
d.join()
t.join()

and these run sequentially (not what I wanted):

d.start()
d.join()
t.start()
t.join()

In particular, I was trying to clever and tidy:

class Kiki(threading.Thread):
    def __init__(self, time):
        super(Kiki, self).__init__()
        self.time = time
        self.start()
        self.join()

This works! But it runs sequentially. I can put the self.start() in __ init __, but not the self.join(). That has to be done after every thread has been started.

join() is what causes the main thread to wait for your thread to finish. Otherwise, your thread runs all by itself.

So one way to think of join() as a "hold" on the main thread -- it sort of de-threads your thread and executes sequentially in the main thread, before the main thread can continue. It assures that your thread is complete before the main thread moves forward. Note that this means it's ok if your thread is already finished before you call the join() -- the main thread is simply released immediately when join() is called.

In fact, it just now occurs to me that the main thread waits at d.join() until thread d finishes before it moves on to t.join().

In fact, to be very clear, consider this code:

import threading
import time

class Kiki(threading.Thread):
    def __init__(self, time):
        super(Kiki, self).__init__()
        self.time = time
        self.start()

    def run(self):
        print self.time, " seconds start!"
        for i in range(0,self.time):
            time.sleep(1)
            print "1 sec of ", self.time
        print self.time, " seconds finished!"


t1 = Kiki(3)
t2 = Kiki(2)
t3 = Kiki(1)
t1.join()
print "t1.join() finished"
t2.join()
print "t2.join() finished"
t3.join()
print "t3.join() finished"

It produces this output (note how the print statements are threaded into each other.)

$ python test_thread.py
32   seconds start! seconds start!1

 seconds start!
1 sec of  1
 1 sec of 1  seconds finished!
 21 sec of
3
1 sec of  3
1 sec of  2
2  seconds finished!
1 sec of  3
3  seconds finished!
t1.join() finished
t2.join() finished
t3.join() finished
$ 

The t1.join() is holding up the main thread. All three threads complete before the t1.join() finishes and the main thread moves on to execute the print then t2.join() then print then t3.join() then print.

Corrections welcome. I'm also new to threading.

(Note: in case you're interested, I'm writing code for a DrinkBot, and I need threading to run the ingredient pumps concurrently rather than sequentially -- less time to wait for each drink.)

Steps I followed 1) Execute the command adb nodaemon server in command prompt Output at command prompt will be: The following error occurred cannot bind 'tcp:5037' The original ADB server port binding failed

2) Enter the following command query which using port 5037 netstat -ano | findstr "5037" The following information will be prompted on command prompt: TCP 127.0.0.1:5037 0.0.0.0:0 LISTENING 9288

3) View the task manager, close all adb.exe

4) Restart eclipse or other IDE

The above steps worked for me.

              jobB = build job: 'k8s-core-user_deploy', propagate: false, wait: true, parameters: [
                         string(name:'environment', value: "${params.environment}"),
                         string(name:'branch_name', value: "${params.branch_name}"),
                         string(name:'service_name', value: "${params.service_name}"),                      
                     ]
            println jobB.getResult()
        }

Even though this solution might seem obvious, I just wanted to post it here so the next guy will google it faster.

If you still want to have the model as a parameter in the method, you can create a DelegatingHandler to buffer the content.

internal sealed class BufferizingHandler : DelegatingHandler
{
    protected override async Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken)
    {
        await request.Content.LoadIntoBufferAsync();
        var result = await base.SendAsync(request, cancellationToken);
        return result;
    }
}

And add it to the global message handlers:

configuration.MessageHandlers.Add(new BufferizingHandler());

This solution is based on the answer by Darrel Miller.

This way all the requests will be buffered.

actually you should only put in-line elements inside the p, so in your case ol is better outside

I prefer simple answers. No generators. No recursion or recursion limits. Just iteration:

def flatten(TheList):
    listIsNested = True

    while listIsNested:                 #outer loop
        keepChecking = False
        Temp = []

        for element in TheList:         #inner loop
            if isinstance(element,list):
                Temp.extend(element)
                keepChecking = True
            else:
                Temp.append(element)

        listIsNested = keepChecking     #determine if outer loop exits
        TheList = Temp[:]

    return TheList

This works with two lists: an inner for loop and an outer while loop.

The inner for loop iterates through the list. If it finds a list element, it (1) uses list.extend() to flatten that part one level of nesting and (2) switches keepChecking to True. keepchecking is used to control the outer while loop. If the outer loop gets set to true, it triggers the inner loop for another pass.

Those passes keep happening until no more nested lists are found. When a pass finally occurs where none are found, keepChecking never gets tripped to true, which means listIsNested stays false and the outer while loop exits.

The flattened list is then returned.

Test-run

flatten([1,2,3,4,[100,200,300,[1000,2000,3000]]])

[1, 2, 3, 4, 100, 200, 300, 1000, 2000, 3000]

VB 6 provides a Clipboard object that makes all of this extremely simple and convenient, but unfortunately that's not available from VBA.

If it were me, I'd go the API route. There's no reason to be scared of calling native APIs; the language provides you with the ability to do that for a reason.

However, a simpler alternative is to use the DataObject class, which is part of the Forms library. I would only recommend going this route if you are already using functionality from the Forms library in your app. Adding a reference to this library only to use the clipboard seems a bit silly.

For example, to place some text on the clipboard, you could use the following code:

Dim clipboard As MSForms.DataObject
Set clipboard = New MSForms.DataObject
clipboard.SetText "A string value"
clipboard.PutInClipboard

Or, to copy text from the clipboard into a string variable:

Dim clipboard As MSForms.DataObject
Dim strContents As String

Set clipboard = New MSForms.DataObject
clipboard.GetFromClipboard
strContents = clipboard.GetText

The best way to do this is this:

datetimepicker.Format = DatetimePickerFormat.Custom;
datetimepicker.CustomFormat = "HH:mm tt";
datetimepicker.ShowUpDowm = true;

Below code works fine before 18 API :-

public String getRealPathFromURI(Uri contentUri) {

        // can post image
        String [] proj={MediaStore.Images.Media.DATA};
        Cursor cursor = managedQuery( contentUri,
                        proj, // Which columns to return
                        null,       // WHERE clause; which rows to return (all rows)
                        null,       // WHERE clause selection arguments (none)
                        null); // Order-by clause (ascending by name)
        int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
        cursor.moveToFirst();

        return cursor.getString(column_index);
}

below code use on kitkat :-

The question has already been marked as answered, But I guess the question states that the person wants to remove multiple columns from a DataTable.

So for that, here is what I did, when I came across the same problem.

string[] ColumnsToBeDeleted = { "col1", "col2", "col3", "col4" };

foreach (string ColName in ColumnsToBeDeleted)
{
    if (dt.Columns.Contains(ColName))
        dt.Columns.Remove(ColName);
}

If you are trying to load a cert from a .pfx file in IIS the solution may be as simple as enabling this option for the Application Pool.

Right click on the App Pool and select Advanced Settings.

Then enable Load User Profile

This may be a good explanation example

CREATE TABLE employees (
id INTEGER NOT NULL PRIMARY KEY,
managerId INTEGER REFERENCES employees(id), 
name VARCHAR(30) NOT NULL
);

INSERT INTO employees(id, managerId, name) VALUES(1, NULL, 'John');
INSERT INTO employees(id, managerId, name) VALUES(2, 1, 'Mike');

-- Explanation: -- In this example. -- John is Mike's manager. Mike does not manage anyone. -- Mike is the only employee who does not manage anyone.

A rephrasal

Another way to phrase the question is "What is the nearest commit that resides on a branch other than the current branch, and which branch is that?"

A solution

You can find it with a little bit of command line magic

git show-branch \
| sed "s/].*//" \
| grep "\*" \
| grep -v "$(git rev-parse --abbrev-ref HEAD)" \
| head -n1 \
| sed "s/^.*\[//" 

With awk:

git show-branch -a \
| grep '\*' \
| grep -v `git rev-parse --abbrev-ref HEAD` \
| head -n1 \
| sed 's/[^\[]*//' \
| awk 'match($0, /\[[a-zA-Z0-9\/-]+\]/) { print substr( $0, RSTART+1, RLENGTH-2 )}'

Here's how it works:

1. Display a textual history of all commits, including remote branches.
2. Ancestors of the current commit are indicated by a star. Filter out everything else.
3. Ignore all the commits in the current branch.
4. The first result will be the nearest ancestor branch. Ignore the other results.
5. Branch names are displayed [in brackets]. Ignore everything outside the brackets, and the brackets.
6. Sometimes the branch name will include a ~# or ^# to indicate how many commits are between the referenced commit and the branch tip. We don't care. Ignore them.

And the Result

Running the above code on

 A---B---D <-master
      \
       \
        C---E---I <-develop
             \
              \
               F---G---H <-topic

Will give you develop if you run it from H and master if you run it from I.

The code is available as a gist

Can you not use AcceptButton in for the Forms Properties Window? This sets the default behaviour for the Enter key press, but you are still able to use other shortcuts.

You could try the following library, it is easy enough and it is just a light wrapper over Microsoft's Open XML SDK (you can even reuse formatting, styles and even entire worksheets from secondary Excel file) : http://officehelper.codeplex.com

The easiest way would be to package the Vagrant box and then copy (e.g. scp or rsync) it over to the other PC, add it and vagrant up ;-)

For detailed steps, check this out => Is there any way to clone a vagrant box that is already installed

I realize this is an old thread, but @alex 's answer needs to be marked as the correct answer

element.getBoundingClientRect() is an exact match to jQuery's $(element).offset()

And it's compatible with IE4+ ... https://developer.mozilla.org/en-US/docs/Web/API/Element.getBoundingClientRect

There's a tidier way to include variables inside the escaped calc, as explained in this post: CSS3 calc() function doesn't work with Less #974

@variable: 2em;

body{ width: calc(~"100% - @{variable} * 2");}

By using the curly brackets you don't need to close and reopen the escaping quotes.

1. Wrap the element inside a div container as a row like your form here or something like that.
2. Set css attribute:
   • width: 30%; (or anything you want)
   • margin: auto; Please take a look on following picture for more detail.

If you are using gvim, you could just hit Ctrl + Home to go the first line. Similarly, Ctrl + End goes to the last line.

One more version... (I think this one is pretty good)

static float NextFloat(Random random)
{
    (float)(float.MaxValue * 2.0 * (rand.NextDouble()-0.5));
}

//inline version
float myVal = (float)(float.MaxValue * 2.0 * (rand.NextDouble()-0.5));

I think this...

• is the 2nd fastest (see benchmarks)
• is evenly distributed

And One more version...(not as good but posting anyway)

static float NextFloat(Random random)
{
    return float.MaxValue * ((rand.Next() / 1073741824.0f) - 1.0f);
}

//inline version
float myVal = (float.MaxValue * ((rand.Next() / 1073741824.0f) - 1.0f));

I think this...

• is the fastest (see benchmarks)
• is evenly distributed however because Next() is a 31 bit random value it will only return 2^31 values. (50% of the neighbor values will have the same value)

Most likely, the item is being selected, you just can't tell because a different control has the focus. There are a couple of different ways that you can solve this, depending on the design of your application.

1. The simple solution is to set the focus to the ListView first whenever your form is displayed. The user typically sets focus to controls by clicking on them. However, you can also specify which controls gets the focus programmatically. One way of doing this is by setting the tab index of the control to 0 (the lowest value indicates the control that will have the initial focus). A second possibility is to use the following line of code in your form's Load event, or immediately after you set the Selected property:

   myListView.Select();
   

   The problem with this solution is that the selected item will no longer appear highlighted when the user sets focus to a different control on your form (such as a textbox or a button).

2. To fix that, you will need to set the HideSelection property of the ListView control to False. That will cause the selected item to remain highlighted, even when the control loses the focus.

   When the control has the focus, the selected item's background will be painted with the system highlight color. When the control does not have the focus, the selected item's background will be painted in the system color used for grayed (or disabled) text.

   You can set this property either at design time, or through code:

   myListView.HideSelection = false;
   

As per my experience CXF is good in terms of configuring it into Spring environment. Also the generated classes are simple to understand. And as it is more active, we get better support in comparison to AXIS or AXIS2.

If you've got all the plugin JS's imported and in the correct order, but you're still having issues, it seems that specifying your own "add" handler nerfs the one from the *-validate.js plugin, which normally would fire off all the validation by calling data.process(). So to fix it just do something like this in your "add" event handler:

$('#whatever').fileupload({
...
add: function(e, data) {
   var $this = $(this);
   data.process(function() {
      return $this.fileupload('process', data);
   }).done(function(){
      //do success stuff
      data.submit(); <-- fire off the upload to the server
   }).fail(function() {
      alert(data.files[0].error);
   });
}
...
});

I had similar problem it was caused by MS UNIT Test DLL. My WPF application was compiled as x86 but unit test DLL (referenced EXE file) as "Any CPU". I changed unit test DLL to be compiled for x86 (same as EXE) and it was resovled.

See in particular Apache HTTPd Password Formats

Default is:

Username: root

Password: [null]

The Password is set to 'password' in some versions.

I came across a similar problem. Somehow, I did not have a build folder in my project. By copying this folder from another project to my project I was having an issue with, this fixed this problem.

You should remove the & (ampersand) symbol, so that line 4 will look like this:

$conn = ADONewConnection($config['db_type']);

This is because ADONewConnection already returns an object by reference. As per documentation, assigning the result of a reference to object by reference results in an E_DEPRECATED message as of PHP 5.3.0

It's not a big deal, it's pretty easy to switch between them. MSTest being integrated isn't a big deal either, just grab testdriven.net.

Like the previous person said pick a mocking framework, my favourite at the moment is Moq.

This answer says to use

mapfile -t myArray < file.txt

I made a shim for mapfile if you want to use mapfile on bash < 4.x for whatever reason. It uses the existing mapfile command if you are on bash >= 4.x

Currently, only options -d and -t work. But that should be enough for that command above. I've only tested on macOS. On macOS Sierra 10.12.6, the system bash is 3.2.57(1)-release. So the shim can come in handy. You can also just update your bash with homebrew, build bash yourself, etc.

It uses this technique to set variables up one call stack.

You can have class something like below from which you can add 'n' number of functions or console_scripts you want to execute in parallel passion and start the execution and wait for all jobs to complete..

jQuery provides a method called "siblings()" which helps us to return all sibling elements of the selected element. For example, if you want to apply CSS to the sibling selectors, you can use this method. Below is an example which illustrates this. You can try this example and play with it to learn how it works.

$("p").siblings("h4").css({"color": "red", "border": "2px solid red"});

This isn't a function of bash, as all the shell does is open the file in question and then pass the file descriptor as the standard output of the script. What you need to do is make sure output is flushed from your script more frequently than you currently are.

In Perl for example, this could be accomplished by setting:

$| = 1;

See perlvar for more information on this.

If you are deeply in recursion inside recursive method, throwing and catching exception may be an option.

Unlike Return that returns only one level up, exception would break out of recursive method as well into the code that initially called it, where it can be catched.

Can be done in two lines :)

Mat to array

uchar * arr = image.isContinuous()? image.data: image.clone().data;
uint length = image.total()*image.channels();

Mat to vector

cv::Mat flat = image.reshape(1, image.total()*image.channels());
std::vector<uchar> vec = image.isContinuous()? flat : flat.clone();

Both work for any general cv::Mat.

Explanation with a working example

    cv::Mat image;
    image = cv::imread(argv[1], cv::IMREAD_UNCHANGED);   // Read the file
    cv::namedWindow("cvmat", cv::WINDOW_AUTOSIZE );// Create a window for display.
    cv::imshow("cvmat", image );                   // Show our image inside it.

    // flatten the mat.
    uint totalElements = image.total()*image.channels(); // Note: image.total() == rows*cols.
    cv::Mat flat = image.reshape(1, totalElements); // 1xN mat of 1 channel, O(1) operation
    if(!image.isContinuous()) {
        flat = flat.clone(); // O(N),
    }
    // flat.data is your array pointer
    auto * ptr = flat.data; // usually, its uchar*
    // You have your array, its length is flat.total() [rows=1, cols=totalElements]
    // Converting to vector
    std::vector<uchar> vec(flat.data, flat.data + flat.total());
    // Testing by reconstruction of cvMat
    cv::Mat restored = cv::Mat(image.rows, image.cols, image.type(), ptr); // OR vec.data() instead of ptr
    cv::namedWindow("reconstructed", cv::WINDOW_AUTOSIZE);
    cv::imshow("reconstructed", restored);

    cv::waitKey(0);     

Extended explanation:

Mat is stored as a contiguous block of memory, if created using one of its constructors or when copied to another Mat using clone() or similar methods. To convert to an array or vector we need the address of its first block and array/vector length.

Pointer to internal memory block

Mat::data is a public uchar pointer to its memory.
But this memory may not be contiguous. As explained in other answers, we can check if mat.data is pointing to contiguous memory or not using mat.isContinous(). Unless you need extreme efficiency, you can obtain a continuous version of the mat using mat.clone() in O(N) time. (N = number of elements from all channels). However, when dealing images read by cv::imread() we will rarely ever encounter a non-continous mat.

Length of array/vector

Q: Should be row*cols*channels right?
A: Not always. It can be rows*cols*x*y*channels.
Q: Should be equal to mat.total()?
A: True for single channel mat. But not for multi-channel mat
Length of the array/vector is slightly tricky because of poor documentation of OpenCV. We have Mat::size public member which stores only the dimensions of single Mat without channels. For RGB image, Mat.size = [rows, cols] and not [rows, cols, channels]. Mat.total() returns total elements in a single channel of the mat which is equal to product of values in mat.size. For RGB image, total() = rows*cols. Thus, for any general Mat, length of continuous memory block would be mat.total()*mat.channels().

Reconstructing Mat from array/vector

Apart from array/vector we also need the original Mat's mat.size [array like] and mat.type() [int]. Then using one of the constructors that take data's pointer, we can obtain original Mat. The optional step argument is not required because our data pointer points to continuous memory. I used this method to pass Mat as Uint8Array between nodejs and C++. This avoided writing C++ bindings for cv::Mat with node-addon-api.

At first, you need to add : after the IP address to indicate the path is following:

scp magento.tar.gz [email protected]:/var/www

I don't think you need to sudo the scp. In this case it doesn't affect the remote machine, only the local command.

Then if your user@xx.x.x.xx doesn't have write access to /var/www then you need to do it in 2 times:

Copy to remote server in your home folder (: represents your remote home folder, use :subfolder/ if needed, or :/home/user/ for full path):

scp magento.tar.gz [email protected]:

Then SSH and move the file:

ssh [email protected]
sudo mv magento.tar.gz /var/www

git log -p will generate the a patch (the diff) for every commit selected. For a single file, use git log --follow -p $file.

If you're looking for a particular change, use git bisect to find the change in log(n) views by splitting the number of commits in half until you find where what you're looking for changed.

Also consider looking back in history using git blame to follow changes to the line in question if you know what that is. This command shows the most recent revision to affect a certain line. You may have to go back a few versions to find the first change where something was introduced if somebody has tweaked it over time, but that could give you a good start.

Finally, gitk as a GUI does show me the patch immediately for any commit I click on.

Example :

Actually emberjs supports two-way binding, which is one of the most powerful feature for a javascript MVC framework. You can check it out where it mentioning binding in its user guide.

for emberjs, to create two way binding is by creating a new property with the string Binding at the end, then specifying a path from the global scope:

App.wife = Ember.Object.create({
  householdIncome: 80000
});

App.husband = Ember.Object.create({
  householdIncomeBinding: 'App.wife.householdIncome'
});

App.husband.get('householdIncome'); // 80000

// Someone gets raise.
App.husband.set('householdIncome', 90000);
App.wife.get('householdIncome'); // 90000

Note that bindings don't update immediately. Ember waits until all of your application code has finished running before synchronizing changes, so you can change a bound property as many times as you'd like without worrying about the overhead of syncing bindings when values are transient.

Hope it helps in extend of original answer selected.

Just in case someone is interest only in what kind of process created the shared moeries, call

ls -l /dev/shm

It lists the names that are associated with the shared memories - at least on Ubuntu. Usually the names are quite telling.

If you use the "select()" statement, you can do this:

$category = $catrep->createQueryBuilder('cc')
    ->select('DISTINCT cc.contenttype')
    ->Where('cc.contenttype = :type')
    ->setParameter('type', 'blogarticle')
    ->getQuery();

$categories = $category->getResult();

This post is very old and I find it very helpful so I decided to share the unset function I wrote in case someone else see this post and think why it's not so simple as it in PHP unset function.

The reason for writing this new unset function, is to keep the index of all other variables in this hash_map. Look at the following example, and see how the index of "test2" did not change after removing a value from the hash_map.

function unset(unsetKey, unsetArr, resort) {
  var tempArr = unsetArr;
  var unsetArr = {};
  delete tempArr[unsetKey];
  if (resort) {
    j = -1;
  }
  for (i in tempArr) {
    if (typeof(tempArr[i]) !== 'undefined') {
      if (resort) {
        j++;
      } else {
        j = i;
      }
      unsetArr[j] = tempArr[i];
    }
  }
  return unsetArr;
}

var unsetArr = ['test', 'deletedString', 'test2'];

console.log(unset('1', unsetArr, true)); // output Object {0: "test", 1: "test2"}
console.log(unset('1', unsetArr, false)); // output Object {0: "test", 2: "test2"}

(x > 0 for x in list) in that function call creates a generator expression eg.

>>> nums = [1, 2, -1, 9, -5]
>>> genexp = (x > 0 for x in nums)
>>> for x in genexp:
        print x


True
True
False
True
False

Which any uses, and shortcircuits on encountering the first object that evaluates True

Why work harder than you have to? postForEntity accepts a simple Map object as input. The following works fine for me while writing tests for a given REST endpoint in Spring. I believe it's the simplest possible way of making a JSON POST request in Spring:

@Test
public void shouldLoginSuccessfully() {
  // 'restTemplate' below has been @Autowired prior to this
  Map map = new HashMap<String, String>();
  map.put("username", "bob123");
  map.put("password", "myP@ssw0rd");
  ResponseEntity<Void> resp = restTemplate.postForEntity(
      "http://localhost:8000/login",
      map,
      Void.class);
  assertThat(resp.getStatusCode()).isEqualTo(HttpStatus.OK);
}

You should use

<div class="row fluid-img">
  <img class="col-lg-12 col-xs-12" src="src.png">
</div>

.fluid-img {
    margin: 60px auto;
}

@media( min-width: 768px ){
        .fluid-img {
            max-width: 768px;
        }
}
@media screen and (min-width: 768px) {
        .fluid-img {
            padding-left: 0;
            padding-right: 0;
        }
}

Update: The world kept turning. Use a functional approach instead.

Here you go:

var arr = [{ key: "11", value: "1100" }, { key: "22", value: "2200" }];
var result = {};
for (var i=0, len=arr.length; i < len; i++) {
    result[arr[i].key] = arr[i].value;
}
console.log(result); // {11: "1000", 22: "2200"}

Google has created a library for easy Permissions management. Its called EasyPermissions

Here is a simple example on requesting Location permission using this library.

public class MainActivity extends AppCompatActivity {

    private final int REQUEST_LOCATION_PERMISSION = 1;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        requestLocationPermission();
    }

    @Override
    public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);

        // Forward results to EasyPermissions
        EasyPermissions.onRequestPermissionsResult(requestCode, permissions, grantResults, this);
    }

    @AfterPermissionGranted(REQUEST_LOCATION_PERMISSION)
    public void requestLocationPermission() {
        String[] perms = {Manifest.permission.ACCESS_FINE_LOCATION};
        if(EasyPermissions.hasPermissions(this, perms)) {
            Toast.makeText(this, "Permission already granted", Toast.LENGTH_SHORT).show();
        }
        else {
            EasyPermissions.requestPermissions(this, "Please grant the location permission", REQUEST_LOCATION_PERMISSION, perms);
        }
    }
}

@AfterPermissionsGranted(REQUEST_CODE) is used to indicate the method that needs to be executed after a permission request with the request code REQUEST_CODE has been granted.

This above case, the method requestLocationPermission() method is called if the user grants the permission to access location services. So, that method acts as both a callback and a method to request the permissions.

You can implement separate callbacks for permission granted and permission denied as well. It is explained in the github page.

One can also try this solution :

To find the value, which is written in span of table

htmlContent

<table>
    <tr>
        <th>
            ID
        </th>
        <th>
            Name
        </th>
    </tr>


    <tr>
        <td>
            <span name="spanId" class="spanclass">ID123</span>
        </td>

        <td>
            <span>Bonny</span>
        </td>
    </tr>
</table>

Python code

soup = BeautifulSoup(htmlContent, "lxml")
soup.prettify()

tables = soup.find_all("table")

for table in tables:
   storeValueRows = table.find_all("tr")
   thValue = storeValueRows[0].find_all("th")[0].string

   if (thValue == "ID"): # with this condition I am verifying that this html is correct, that I wanted.
      value = storeValueRows[1].find_all("span")[0].string
      value = value.strip()

      # storeValueRows[1] will represent <tr> tag of table located at first index and find_all("span")[0] will give me <span> tag and '.string' will give me value

      # value.strip() - will remove space from start and end of the string.

     # find using attribute :

     value = storeValueRows[1].find("span", {"name":"spanId"})['class']
     print value
     # this will print spanclass

In your example, the TMP variable is set (and the temporary directory created) whenever the rules for out.tar are evaluated. In order to create the directory only when out.tar is actually fired, you need to move the directory creation down into the steps:

out.tar : 
    $(eval TMP := $(shell mktemp -d))
    @echo hi $(TMP)/hi.txt
    tar -C $(TMP) cf $@ .
    rm -rf $(TMP)

The eval function evaluates a string as if it had been typed into the makefile manually. In this case, it sets the TMP variable to the result of the shell function call.

edit (in response to comments):

To create a unique variable, you could do the following:

out.tar : 
    $(eval $@_TMP := $(shell mktemp -d))
    @echo hi $($@_TMP)/hi.txt
    tar -C $($@_TMP) cf $@ .
    rm -rf $($@_TMP)

This would prepend the name of the target (out.tar, in this case) to the variable, producing a variable with the name out.tar_TMP. Hopefully, that is enough to prevent conflicts.

find {directory} -type f -name '*.extension'

Example: To find all csv files in the current directory and its sub-directories, use:

find . -type f -name '*.csv'

if you div looks like this:

<div id="someId">Some Value</div>

you could retrieve it with jquery like this:

$('#someId').text()

I appreciate this is a very old question but I thought I would add another answer for future users as all the answers to date use some form of Assembly.GetTypes.

Whilst GetTypes() will indeed return all types, it does not necessarily mean you could activate them and could thus potentially throw a ReflectionTypeLoadException.

A classic example for not being able to activate a type would be when the type returned is derived from base but base is defined in a different assembly from that of derived, an assembly that the calling assembly does not reference.

So say we have:

Class A // in AssemblyA
Class B : Class A, IMyInterface // in AssemblyB
Class C // in AssemblyC which references AssemblyB but not AssemblyA

If in ClassC which is in AssemblyC we then do something as per accepted answer:

var type = typeof(IMyInterface);
var types = AppDomain.CurrentDomain.GetAssemblies()
    .SelectMany(s => s.GetTypes())
    .Where(p => type.IsAssignableFrom(p));

Then it will throw a ReflectionTypeLoadException.

This is because without a reference to AssemblyA in AssemblyC you would not be able to:

var bType = typeof(ClassB);
var bClass = (ClassB)Activator.CreateInstance(bType);

In other words ClassB is not loadable which is something that the call to GetTypes checks and throws on.

So to safely qualify the result set for loadable types then as per this Phil Haacked article Get All Types in an Assembly and Jon Skeet code you would instead do something like:

public static class TypeLoaderExtensions {
    public static IEnumerable<Type> GetLoadableTypes(this Assembly assembly) {
        if (assembly == null) throw new ArgumentNullException("assembly");
        try {
            return assembly.GetTypes();
        } catch (ReflectionTypeLoadException e) {
            return e.Types.Where(t => t != null);
        }
    }
}

And then:

private IEnumerable<Type> GetTypesWithInterface(Assembly asm) {
    var it = typeof (IMyInterface);
    return asm.GetLoadableTypes().Where(it.IsAssignableFrom).ToList();
}

File could not be Attached from client PC (upload)

In the HTML form I have not added following line, so no attachment was going:

enctype="multipart/form-data"

After adding above line in form (as below), the attachment went perfect.

<form id="form1" name="form1" method="post" action="form_phpm_mailer.php"  enctype="multipart/form-data">

function validateNumber(e) {_x000D_
            const pattern = /^[0-9]$/;_x000D_
_x000D_
            return pattern.test(e.key )_x000D_
        }

 _x000D_
 <input name="username" id="username" onkeypress="return validateNumber(event)">

This approach doesn't lock numlock numbers, arrows, home, end buttons and etc

Just Navigate to Settings->Permalink in your dashboard and then Save Changes button in the last.\

To be honest I think that it's really shame that there is no simple checkbox in storyboard to say that you want to resize buttons to accommodate the text. Well... whatever.

Here is the simplest solution using storyboard.

1. Place UIView and put constraints for it. Example:

2. Place UILabel inside UIView. Set constraints to attach it to edges of UIView.

3. Place your UIButton inside UIView. Set the same constraints to attach it to the edges of UIView.

4. Set 0 for UILabel's number of lines.

5. Set up the outlets.

    @IBOutlet var button: UIButton!
    @IBOutlet var textOnTheButton: UILabel!

6. Get some long, long, long title.

    let someTitle = "Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum."

7. On viewDidLoad set the title both for UILabel and UIButton.

    override func viewDidLoad() {
        super.viewDidLoad()
        textOnTheButton.text = someTitle
        button.setTitle(someTitle, for: .normal)
        button.titleLabel?.numberOfLines = 0
    }

8. Run it to make sure that button is resized and can be pressed.

For a timestamp with microsecond resolution, there's performance.now:

function time() { 
  return performance.now() + performance.timing.navigationStart;
}

This could for example yield 1436140826653.139, while Date.now only gives 1436140826653.

Basically, you need to catch the OperationCanceledException and check the state of the cancellation token that was passed to SendAsync (or GetAsync, or whatever HttpClient method you're using):

• if it was canceled (IsCancellationRequested is true), it means the request really was canceled
• if not, it means the request timed out

Of course, this isn't very convenient... it would be better to receive a TimeoutException in case of timeout. I propose a solution here based on a custom HTTP message handler: Better timeout handling with HttpClient

I use Windows 10 Bash shell aka Linux Subsystem aka Ubuntu in Windows 10 as guided here

This is working sample that i have tried :

Open your mail.php under config folder then fill with this option :

'driver'     => env('MAIL_DRIVER', 'smtp'),
'host'       => env('MAIL_HOST', 'smtp.gmail.com'),
'port'       => env('MAIL_PORT', 587),
'from'       => ['address' =>'[email protected]', 'name' => 'Email_Subject'],
'encryption' => env('MAIL_ENCRYPTION', 'tls'),
'username'   => env('MAIL_USERNAME','[email protected]'),
'password'   => env('MAIL_PASSWORD','youremailpassword'),
'sendmail'   => '/usr/sbin/sendmail -bs',

Open your .env file under root project. Also edit this file following above option such

MAIL_DRIVER=smtp    
MAIL_HOST=smtp.gmail.com   
MAIL_PORT=587      
MAIL_USERNAME=youremailusername
MAIL_PASSWORD=youremailpassword
MAIL_ENCRYPTION=tls

After that clear your config by running this command

php artisan config:cache

Restart your local server

Try visit your route with controller contains mail function at first time it still error Authentication Required. You need to login via your gmail account to authorize untrusted connection. Visit this link to authorize

Here is an alternative way to solve this using a DIV and the 'contenteditable' property:

HTML:

<div contenteditable = "true" class = "fluidInput" data-placeholder = ""></div>

CSS: (to give the DIV some dimensions and make it easier to see)

.fluidInput {

    display         : inline-block;
    vertical-align  : top;

    min-width       : 1em;
    height          : 1.5em;

    font-family     : Arial, Helvetica, sans-serif;
    font-size       : 0.8em;
    line-height     : 1.5em;

    padding         : 0px 2px 0px 2px;
    border          : 1px solid #aaa;
    cursor          : text;
}


.fluidInput * {

    display         : inline;

}


.fluidInput br  {

    display         : none;

}


.fluidInput:empty:before {

    content         : attr(data-placeholder);
    color           : #ccc;

}

Note: If you are planning on using this inside of a FORM element that you plan to submit, you will need to use Javascript / jQuery to catch the submit event so that you can parse the 'value' ( .innerHTML or .html() respectively) of the DIV.

Check this article. One example from there:

@Test  
public void listEquality() {  
    List<Integer> expected = new ArrayList<Integer>();  
    expected.add(5);  

    List<Integer> actual = new ArrayList<Integer>();  
    actual.add(5);  

    assertEquals(expected, actual);  
}  

If you are using jQuery, you don't have to do anything special. Handlers added via $(document).ready() don't overwrite each other, but rather execute in turn:

$(document).ready(func1)
...
$(document).ready(func2)

If you are not using jQuery, you could use addEventListener, as demonstrated by Karaxuna, plus attachEvent for IE<9.

Note that onload is not equivalent to $(document).ready() - the former waits for CSS, images... as well, while the latter waits for the DOM tree only. Modern browsers (and IE since IE9) support the DOMContentLoaded event on the document, which corresponds to the jQuery ready event, but IE<9 does not.

if(window.addEventListener){
  window.addEventListener('load', func1)
}else{
  window.attachEvent('onload', func1)
}
...
if(window.addEventListener){
  window.addEventListener('load', func2)
}else{
  window.attachEvent('onload', func2)
}

If neither option is available (for example, you are not dealing with DOM nodes), you can still do this (I am using onload as an example, but other options are available for onload):

var oldOnload1=window.onload;
window.onload=function(){
  oldOnload1 && oldOnload1();
  func1();
}
...
var oldOnload2=window.onload;
window.onload=function(){
  oldOnload2 && oldOnload2();
  func2();
}

or, to avoid polluting the global namespace (and likely encountering namespace collisions), using the import/export IIFE pattern:

window.onload=(function(oldLoad){
  return function(){
    oldLoad && oldLoad();
    func1();
  }
})(window.onload)
...
window.onload=(function(oldLoad){
  return function(){
    oldLoad && oldLoad();
    func2();
  }
})(window.onload)

How to run a script in Ipython

In my case the problem was related to "Referencing .NET standard library in classic asp.net projects" and these two issues

The code you posted works for me with the latest version of Mockito and Powermockito. Maybe you haven't prepared A? Try this:

A.java

public class A {
     private final String test;

    public A(String test) {
        this.test = test;
    }

    public String check() {
        return "checked " + this.test;
    }
}

MockA.java

import static org.hamcrest.MatcherAssert.assertThat;
import static org.hamcrest.Matchers.equalTo;
import static org.mockito.Mockito.mock;
import static org.mockito.Mockito.when;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.Mockito;
import org.powermock.api.mockito.PowerMockito;
import org.powermock.core.classloader.annotations.PrepareForTest;
import org.powermock.modules.junit4.PowerMockRunner;

@RunWith(PowerMockRunner.class)
@PrepareForTest(A.class)
public class MockA {
    @Test
    public void test_not_mocked() throws Throwable {
        assertThat(new A("random string").check(), equalTo("checked random string"));
    }
    @Test
    public void test_mocked() throws Throwable {
         A a = mock(A.class); 
         when(a.check()).thenReturn("test");
         PowerMockito.whenNew(A.class).withArguments(Mockito.anyString()).thenReturn(a);
         assertThat(new A("random string").check(), equalTo("test"));
    }
}

Both tests should pass with mockito 1.9.0, powermockito 1.4.12 and junit 4.8.2

Try this out:

$url = 'http://techcrunch.com/startups/'; $url = str_replace(array('http://', 'https://'), '', $url); 

EDIT:

Or, a simple way to always remove the protocol:

$url = 'https://www.google.com/'; $url = preg_replace('@^.+?\:\/\/@', '', $url); 

you can also just change your delete to a select *

and test your selection

the records selected will be the same as the ones deleted

you can also wrap your statement in a begin / rollback if you are not sure - test the statement then if all is good remove rollback

for example

SELECT * FROM table WHERE id BETWEEN 79 AND 296

will show all the records matching the where if they are the wants you 'really' want to delete then use

DELETE FROM table WHERE id BETWEEN 79 AND 296

You can also create a trigger / which catches deletes and puts them into a history table

so if you delete something by mistake you can always get it back

(keep your history table records no older than say 6 months or whatever business rules say)

A bit of explaining as to what that %2520 is :

The common space character is encoded as %20 as you noted yourself. The % character is encoded as %25.

The way you get %2520 is when your url already has a %20 in it, and gets urlencoded again, which transforms the %20 to %2520.

Are you (or any framework you might be using) double encoding characters?

Edit: Expanding a bit on this, especially for LOCAL links. Assuming you want to link to the resource C:\my path\my file.html:

• if you provide a local file path only, the browser is expected to encode and protect all characters given (in the above, you should give it with spaces as shown, since % is a valid filename character and as such it will be encoded) when converting to a proper URL (see next point).
• if you provide a URL with the file:// protocol, you are basically stating that you have taken all precautions and encoded what needs encoding, the rest should be treated as special characters. In the above example, you should thus provide file:///c:/my%20path/my%20file.html. Aside from fixing slashes, clients should not encode characters here.

NOTES:

• Slash direction - forward slashes / are used in URLs, reverse slashes \ in Windows paths, but most clients will work with both by converting them to the proper forward slash.
• In addition, there are 3 slashes after the protocol name, since you are silently referring to the current machine instead of a remote host ( the full unabbreviated path would be file://localhost/c:/my%20path/my%file.html ), but again most clients will work without the host part (ie two slashes only) by assuming you mean the local machine and adding the third slash.

The easisest thing to do is to wrap your code in a transaction, and then execute each batch of T-SQL code line by line.

For example,

Begin Transaction

         -Do some T-SQL queries here.

Rollback transaction -- OR commit transaction

If you want to incorporate error handling you can do so by using a TRY...CATCH BLOCK. Should an error occur you can then rollback the tranasction within the catch block.

For example:

USE AdventureWorks;
GO
BEGIN TRANSACTION;

BEGIN TRY
    -- Generate a constraint violation error.
    DELETE FROM Production.Product
    WHERE ProductID = 980;
END TRY
BEGIN CATCH
    SELECT 
        ERROR_NUMBER() AS ErrorNumber
        ,ERROR_SEVERITY() AS ErrorSeverity
        ,ERROR_STATE() AS ErrorState
        ,ERROR_PROCEDURE() AS ErrorProcedure
        ,ERROR_LINE() AS ErrorLine
        ,ERROR_MESSAGE() AS ErrorMessage;

    IF @@TRANCOUNT > 0
        ROLLBACK TRANSACTION;
END CATCH;

IF @@TRANCOUNT > 0
    COMMIT TRANSACTION;
GO

If you want change background color on button click, you should use JavaScript function and change a style in the HTML page.

function chBackcolor(color) {
   document.body.style.background = color;
}

It is a function in JavaScript for change color, and you will be call this function in your event, for example :

<input type="button" onclick="chBackcolor('red');">

I recommend to use jQuery for this.

If you want it only for some seconds, you can use setTimeout function:

window.setTimeout("chBackColor()",10000);

Is there a reason why you can't use the Excel ODBC connection to read and write to Excel? For example, I've used the following code to read from an Excel file row by row like a database:

private DataTable LoadExcelData(string fileName)
{
  string Connection = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + fileName + ";Extended Properties=\"Excel 12.0;HDR=Yes;IMEX=1\";";

  OleDbConnection con = new OleDbConnection(Connection);

  OleDbCommand command = new OleDbCommand();

  DataTable dt = new DataTable(); OleDbDataAdapter myCommand = new OleDbDataAdapter("select * from [Sheet1$] WHERE LastName <> '' ORDER BY LastName, FirstName", con);

  myCommand.Fill(dt);

  Console.WriteLine(dt.Rows.Count);

  return dt;

You can write to the Excel "database" the same way. As you can see, you can select the version number to use so that you can downgrade Excel versions for the machine with Excel 2003. Actually, the same is true for using the Interop. You can use the lower version and it should work with Excel 2003 even though you only have the higher version on your development PC.

git show

is the fastest to type, but shows you the diff as well.

git log -1

is fast and simple.

git log -1 --pretty=%B

if you need just the commit message and nothing else.

INADDR_ANY is used when you don't need to bind a socket to a specific IP. When you use this value as the address when calling bind(), the socket accepts connections to all the IPs of the machine.

With bash you may use read like tis:

#!/usr/bin/env bash

{ IFS= read -rd '' value <config.txt;} 2>/dev/null

printf '%s' "$value"

Notice that:

• The last newline is preserved.

• The stderr is silenced to /dev/null by redirecting the whole commands block, but the return status of the read command is preserved, if one needed to handle read error conditions.

From CREATE FUNCTION:

When a parameter of the function has a default value, the keyword DEFAULT must be specified when the function is called to retrieve the default value. This behavior is different from using parameters with default values in stored procedures in which omitting the parameter also implies the default value.

So you need to do:

SELECT dbo.fCalculateEstimateDate(647,DEFAULT)

You can use (':hidden') method to find if your div is visible or not.. Also its a good practice to cache a element if you are using it multiple times in your code..

$(".subpanel a").click(function() 
     {
        var chatterNickname = $(this).text();
        var $chatPanel = $("#singlechatpanel-1");

        if(!$chatPanel.is(':hidden'))
        {
            alert("Room 1 is filled.");
            $chatPanel.show();
            $("#singlechatpanel-1 #chatter_nickname").html("Chatting with: " + chatterNickname);
        }
});

Use this function:

$(".price").each(function(){
total_price += parseInt($(this).val());
});

I'm using IronPython here (same as .NET API) and reading the file as UTF-8 in order to properly handle the BOM fixed the problem for me:

xmlFile = Path.Combine(directory_str, 'file.xml')
doc = XPathDocument(XmlTextReader(StreamReader(xmlFile.ToString(), Encoding.UTF8)))

It would work as well with the XmlDocument:

doc = XmlDocument()
doc.Load(XmlTextReader(StreamReader(xmlFile.ToString(), Encoding.UTF8)))

You need to explicitly tell Java that you wish to multiply.

(x1-x2) * (x1-x2) + (y1-y2) * (y1-y2)

Unlike written equations the compiler does not know this is what you wish to do.

To remove all cookies you could write:

foreach ($_COOKIE as $key => $value) {
    unset($value);
    setcookie($key, '', time() - 3600);
}

Came across the question myself today. I think the reason that your code returns 'None' (exactly what I got by using the same method) is that

a.sort()

is calling the sort function to mutate the list a. In my understanding, this is a modification command. To see the result you have to use print(a).

My solution, as I tried to keep everything in pandas:

pd.Series(df['A'].unique()).sort_values()

Setting cookie in the express is easy

1. first install cookie parser

npm install cookie parser

2. using middleware

const cookieParser = require('cookie-parser');
app.use(cookieParser());

3. Set cookie know more

res.cookie('cookieName', '1', { expires: new Date(Date.now() + 900000), httpOnly: true })

4. Accessing that cookie know more

console.dir(req.cookies.cookieName)

I'm pretty mixed up on this. I am also running Excel 2010. I tried saving two sheets as a single PDF using:

    ThisWorkbook.Sheets(Array(1,2)).Select
    **Selection**.ExportAsFixedFormat xlTypePDF, FileName & ".pdf", , , False

but I got nothing but blank pages. It saved both sheets, but nothing on them. It wasn't until I used:

    ThisWorkbook.Sheets(Array(1,2)).Select
    **ActiveSheet**.ExportAsFixedFormat xlTypePDF, FileName & ".pdf", , , False

that I got a single PDF file with both sheets.

I tried manually saving these two pages using Selection in the Options dialog to save the two sheets I had selected, but got blank pages. When I tried the Active Sheet(s) option, I got what I wanted. When I recorded this as a macro, Excel used ActiveSheet when it successfully published the PDF. What gives?

On SQL 2017 - Database A has synonyms to Database B. User can connect to database A and has exec rights to an sp (on A) that refers to the synonyms that point to B. User was set up with connect access B. Only when granting CONNECT to the public group to database B did the sp on A work. I don't recall this working this way on 2012 as granting connect to the user only seemed to work.

From API 21 `getDrawable(int id)` is deprecated

So now you need to use

ResourcesCompat.getDrawable(context.getResources(), R.drawable.img_user, null)

But Best way to do is :

object ResourceUtils {
    fun getColor(context: Context, color: Int): Int {
        return ResourcesCompat.getColor(context.getResources(), color, null)
    }

    fun getDrawable(context: Context, drawable: Int): Drawable? {
        return ResourcesCompat.getDrawable(context.getResources(), drawable, null)
    }
}

use this method like :

Drawable img=ResourceUtils.getDrawable(context, R.drawable.img_user)
image.setImageDrawable(img);

You can also use linq extensions for DataSets:

var imagePaths = dt.AsEnumerble().Select(r => r.Field<string>("ImagePath");
foreach(string imgPath in imagePaths)
{
    TextBox1.Text = imgPath;
}

The rifle clip analogy posted by Oren A is pretty good, but I'll try another one and try to anticipate what the instructor was trying to get across.

A stack, as it's name suggests is an arrangement of "things" that has:

• A top
• A bottom
• An ordering in between the top and bottom (e.g. second from the top, 3rd from the bottom).

(think of it as a literal stack of books on your desk and you can only take something from the top)

Pushing something on the stack means "placing it on top". Popping something from the stack means "taking the top 'thing'" off the stack.

A simple usage is for reversing the order of words. Say I want to reverse the word: "popcorn". I push each letter from left to right (all 7 letters), and then pop 7 letters and they'll end up in reverse order. It looks like this was what he was doing with those expressions.

push(p) push(o) push(p) push(c) push(o) push(r) push(n)

after pushing the entire word, the stack looks like:

   |  n   |  <- top
   |  r   |
   |  o   |
   |  c   |
   |  p   |
   |  o   |
   |  p   |  <- bottom (first "thing" pushed on an empty stack)
    ======

when I pop() seven times, I get the letters in this order:

n,r,o,c,p,o,p

conversion of infix/postfix/prefix is a pathological example in computer science when teaching stacks:

Infix to Postfix conversion.

Post fix conversion to an infix expression is pretty straight forward:

(scan expression from left to right)

1. For every number (operand) push it on the stack.
2. Every time you encounter an operator (+,-,/,*) pop twice from the stack and place the operator between them. Push that on the stack:

So if we have 53+2* we can convert that to infix in the following steps:

1. Push 5.
2. Push 3.
3. Encountered +: pop 3, pop 5, push 5+3 on stack (be consistent with ordering of 5 and 3)
4. Push 2.
5. Encountered *: pop 2, pop (5+3), push (2 * (5+3)).

*When you reach the end of the expression, if it was formed correctly you stack should only contain one item.

By introducing 'x' and 'o' he may have been using them as temporary holders for the left and right operands of an infix expression: x + o, x - o, etc. (or order of x,o reversed).

There's a nice write up on wikipedia as well. I've left my answer as a wiki incase I've botched up any ordering of expressions.

From the release news of ggplot 2.2.0: "The main plot title is now left-aligned to better work better with a subtitle". See also the plot.title argument in ?theme: "left-aligned by default".

As pointed out by @J_F, you may add theme(plot.title = element_text(hjust = 0.5)) to center the title.

ggplot() +
  ggtitle("Default in 2.2.0 is left-aligned")

ggplot() +
  ggtitle("Use theme(plot.title = element_text(hjust = 0.5)) to center") +
  theme(plot.title = element_text(hjust = 0.5))

I was facing the same issue in which I need to align selected placeholder value to the right of the select box & also need to align options to right but when I have used direction: rtl; to select & applied some right padding to select then all options also getting shift to the right by padding as I only want to apply padding to selected placeholder.

I have fixed the issue by the following the style:

select:first-child{
  text-indent: 24%;
  direction: rtl;
  padding-right: 7px;
}

select option{
  direction: rtl;
}

You can change text-indent as per your requirement. Hope it will help you.

Insted of using System.Net.WebClient I would recommend to have a look on System.Net.Http.HttpClient which was introduced with net 4.5 and makes your life much easier.

Also microsoft recommends to use the HttpClient on this article

http://msdn.microsoft.com/en-us/library/system.net.webclient(VS.90).aspx

An example could look like this:

var client = new HttpClient();
var content = new MultipartFormDataContent
{
     { new StringContent("myUserId"), "userid"},
     { new StringContent("myFileName"), "filename"},
     { new StringContent("myPassword"), "password"},
     { new StringContent("myType"), "type"}
};

var responseMessage = await client.PostAsync("some url", content);        
var stream = await responseMessage.Content.ReadAsStreamAsync();

To make a dropdown list you need two properties:

1. a property to which you will bind to (usually a scalar property of type integer or string)
2. a list of items containing two properties (one for the values and one for the text)

In your case you only have a list of string which cannot be exploited to create a usable drop down list.

While for number 2. you could have the value and the text be the same you need a property to bind to. You could use a weakly typed version of the helper:

@model List<string>
@Html.DropDownList(
    "Foo", 
    new SelectList(
        Model.Select(x => new { Value = x, Text = x }),
        "Value",
        "Text"
    )
)

where Foo will be the name of the ddl and used by the default model binder. So the generated markup might look something like this:

<select name="Foo" id="Foo">
    <option value="item 1">item 1</option>
    <option value="item 2">item 2</option>
    <option value="item 3">item 3</option>
    ...
</select>

This being said a far better view model for a drop down list is the following:

public class MyListModel
{
    public string SelectedItemId { get; set; }
    public IEnumerable<SelectListItem> Items { get; set; }
}

and then:

@model MyListModel
@Html.DropDownListFor(
    x => x.SelectedItemId,
    new SelectList(Model.Items, "Value", "Text")
)

and if you wanted to preselect some option in this list all you need to do is to set the SelectedItemId property of this view model to the corresponding Value of some element in the Items collection.

The simplest way (using Apache Common Codec):

byte[] bytes = Hex.decodeHex(str.toCharArray());

Just get the Eclipse Memory Analyzer. There's nothing better out there and it's free.

JHAT is only usable for "toy applications"

1. Go to structure view of the table
   
2. You will see 2 option at top a.Table structure b.Relation view.
   
3. Now click on Relation view , here you can drop your foreign key constraint. You will get all relation here.

You should use the I/O Library where you can find all functions at the io table and then use file:read to get the file content.

local open = io.open

local function read_file(path)
    local file = open(path, "rb") -- r read mode and b binary mode
    if not file then return nil end
    local content = file:read "*a" -- *a or *all reads the whole file
    file:close()
    return content
end

local fileContent = read_file("foo.html");
print (fileContent);

That didn't really work in my case - i.e. in order to overwrite hosts file you have to follow it's directions, ie:

./emulator -avd myEmulatorName -partition-size 280

and then in other term window (pushing new hosts file /tmp/hosts):

./adb remount
./adb push /tmp/hosts /system/etc

Re: textFile.getch(), did you make that up, or do you have a reference that says it should work? If it's the latter, get rid of it. If it's the former, don't do that. Get a good reference.

char ch;
textFile.unsetf(ios_base::skipws);
textFile >> ch;

In C, use the strstr() standard library function:

const char *str = "/user/desktop/abc/post/";
const int exists = strstr(str, "/abc/") != NULL;

Take care to not accidentally find a too-short substring (this is what the starting and ending slashes are for).

I faced this issue a lot when using position: absolute;, I faced this issue by using position: relative in the child element. don't need to change position: absolute to relative, just need to add in the child element look into the beneath two examples:

let toggle = document.getElementById('toggle')

toggle.addEventListener("click", () => {
 toggle.classList.toggle('change');
})

.container {
  width: 60px;
  height: 22px;
  background: #333;
  border-radius: 20px;
  position: relative;
  cursor: pointer;

}

.change .slide {
  transform: translateX(33px);
}

.slide {
  transition: 0.5s;
  width: 20px;
  height: 20px;
  background: #fff;
  border-radius: 20px;
  margin: 2px 2px;
  z-index: 100;
}

.dot {
  width: 10px;
  height: 16px;
  background: red;
  position: absolute;
  top: 4px;
  right: 5px;
  z-index: 1;
}

<div class="container" id="toggle">
  <div class="slide"></div>
  <div class="dot"></div>
</div>

This's how it can be fixed using position relative:

let toggle = document.getElementById('toggle')

toggle.addEventListener("click", () => {
 toggle.classList.toggle('change');
})

.container {
  width: 60px;
  height: 22px;
  background: #333;
  border-radius: 20px;
  position: relative;
  cursor: pointer;

}

.change .slide {
  transform: translateX(33px);
}

.slide {
  transition: 0.5s;
  width: 20px;
  height: 20px;
  background: #fff;
  border-radius: 20px;
  margin: 2px 2px;
  z-index: 100;
  
  // Just add position relative;
  position: relative;
}

.dot {
  width: 10px;
  height: 16px;
  background: red;
  position: absolute;
  top: 4px;
  right: 5px;
  z-index: 1;
}

<div class="container" id="toggle">
  <div class="slide"></div>
  <div class="dot"></div>
</div>

Sandbox here

Well, I have a tricky method for this job. The idea is as follow-

Make some invisible HTML tags like <label>, <p>, <input> etc. in HTML body and make a pattern in tag id, for example, use list index in tag id and list value at tag class name.

Here I have two lists maintenance_next[] and maintenance_block_time[] of the same length. I want to pass these two list's data to javascript using the flask. So I take some invisible label tag and set its tag name is a pattern of list index and set its class name as value at index.

{% for i in range(maintenance_next|length): %}_x000D_
<label id="maintenance_next_{{i}}" name="{{maintenance_next[i]}}" style="display: none;"></label>_x000D_
<label id="maintenance_block_time_{{i}}" name="{{maintenance_block_time[i]}}" style="display: none;"></label>_x000D_
{% endfor%}

After this, I retrieve the data in javascript using some simple javascript operation.

<script>_x000D_
var total_len = {{ total_len }};_x000D_
_x000D_
for (var i = 0; i < total_len; i++) {_x000D_
    var tm1 = document.getElementById("maintenance_next_" + i).getAttribute("name");_x000D_
    var tm2 = document.getElementById("maintenance_block_time_" + i).getAttribute("name");_x000D_
    _x000D_
    //Do what you need to do with tm1 and tm2._x000D_
    _x000D_
    console.log(tm1);_x000D_
    console.log(tm2);_x000D_
}_x000D_
</script>

For those using npm to install packages, you can install jquery via npm install jquery and then use elixir to compile jquery and your other npm packages into one file (e.g. vendor.js). Here's a sample gulpfile.js

var elixir = require('laravel-elixir');

elixir(function(mix) {
    mix

    .scripts([
        'jquery/dist/jquery.min.js',
        // list your other npm packages here
    ],
    'public/js/vendor.js', // 2nd param is the output file
    'node_modules')        // 3rd param is saying "look in /node_modules/ for these scripts"

    .scripts([
        'scripts.js'       // your custom js file located in default location: /resources/assets/js/
    ], 'public/js/app.js') // looks in default location since there's no 3rd param

    .version([             // optionally append versioning string to filename
        'js/vendor.js',    // compiled files will be in /public/build/js/
        'js/app.js'
    ]);

});

The correct answer that worked for me on CentOS is

/etc/init.d/mysql restart

which is an init script and not /etc/init.d/mysqld restart, which is binary

The is in fact comment of @MrTux on the question which worked for me. It took quite a bit of my time hence posting it as answer.

I think you missed a equal sign at:

Cursor c = ourDatabase.query(DATABASE_TABLE, column, KEY_ROWID + "" + l, null, null, null, null);  

Change to:

Cursor c = ourDatabase.query(DATABASE_TABLE, column, KEY_ROWID + " = " + l, null, null, null, null); 

So I started experimenting with the different things that FileReader API had to offer and could create an IMG tag with a DATA URL.

        _x000D_
        img.onload = function() { _x000D_
//I loaded the image and have complete control over all attributes, like width and src, which is the purpose of filereader._x000D_
            $.ajax({url: img.src, async: false, success: function(result){_x000D_

When you use re.split and the split pattern contains capturing groups, the groups are retained in the output. If you don't want this, use a non-capturing group instead.

pip version 10 has an issue. It will manifest as the error:

ubuntu@mymachine-:~/mydir$ sudo pip install --upgrade pip
Traceback (most recent call last):
  File "/usr/bin/pip", line 9, in <module>
    from pip import main
ImportError: cannot import name main

The solution is to be in the venv you want to upgrade and then run:

sudo myvenv/bin/pip install --upgrade pip

rather than just

sudo pip install --upgrade pip

It is possible, they are not connected in InterfaceBuilder.

Text colour(colorWithRed:(188/255) green:(149/255) blue:(88/255)) is correct, may be mistake in connections,

backgroundcolor is used for the background colour of label and textcolor is used for property textcolor.

For detailed instructions on how to get a unique identifier for each Android device your application is installed from, see the official Android Developers Blog posting Identifying App Installations.

It seems the best way is for you to generate one yourself upon installation and subsequently read it when the application is re-launched.

I personally find this acceptable but not ideal. No one identifier provided by Android works in all instances as most are dependent on the phone's radio states (Wi-Fi on/off, cellular on/off, Bluetooth on/off). The others, like Settings.Secure.ANDROID_ID must be implemented by the manufacturer and are not guaranteed to be unique.

The following is an example of writing data to an installation file that would be stored along with any other data the application saves locally.

public class Installation {
    private static String sID = null;
    private static final String INSTALLATION = "INSTALLATION";

    public synchronized static String id(Context context) {
        if (sID == null) {
            File installation = new File(context.getFilesDir(), INSTALLATION);
            try {
                if (!installation.exists())
                    writeInstallationFile(installation);
                sID = readInstallationFile(installation);
            } 
            catch (Exception e) {
                throw new RuntimeException(e);
            }
        }
        return sID;
    }

    private static String readInstallationFile(File installation) throws IOException {
        RandomAccessFile f = new RandomAccessFile(installation, "r");
        byte[] bytes = new byte[(int) f.length()];
        f.readFully(bytes);
        f.close();
        return new String(bytes);
    }

    private static void writeInstallationFile(File installation) throws IOException {
        FileOutputStream out = new FileOutputStream(installation);
        String id = UUID.randomUUID().toString();
        out.write(id.getBytes());
        out.close();
    }
}

You will not be able to retrieve a plain text password from wordpress.

Wordpress use a 1 way encryption to store the passwords using a variation of md5. There is no way to reverse this.

See this article for more info http://wordpress.org/support/topic/how-is-the-user-password-encrypted-wp_hash_password

I was actually searching for a similar error and Google sent me here to this question. The error was:

The type arguments for method 'IModelExpressionProvider.CreateModelExpression(ViewDataDictionary, Expression>)' cannot be inferred from the usage

I spent maybe 15 minutes trying to figure it out. It was happening inside a Razor .cshtml view file. I had to comment portions of the view code to get to where it was barking since the compiler didn't help much.

<div class="form-group col-2">
    <label asp-for="Organization.Zip"></label>
    <input asp-for="Organization.Zip" class="form-control">
    <span asp-validation-for="Zip" class="color-type-alert"></span>
</div>

Can you spot it? Yeah... I re-checked it maybe twice and didn't get it at first!

See that the ViewModel's property is just Zip when it should be Organization.Zip. That was it.

So re-check your view source code... :-)

It seems that in PHP 7.1, a Warning will be emitted if a non-numeric value is encountered. See this link.

Here is the relevant portion that pertains to the Warning notice you are getting:

New E_WARNING and E_NOTICE errors have been introduced when invalid strings are coerced using operators expecting numbers or their assignment equivalents. An E_NOTICE is emitted when the string begins with a numeric value but contains trailing non-numeric characters, and an E_WARNING is emitted when the string does not contain a numeric value.

I'm guessing either $item['quantity'] or $product['price'] does not contain a numeric value, so make sure that they do before trying to multiply them. Maybe use some sort of conditional before calculating the $sub_total, like so:

<?php

if (is_numeric($item['quantity']) && is_numeric($product['price'])) {
  $sub_total += ($item['quantity'] * $product['price']);
} else {
  // do some error handling...
}

Calling conventions defines how parameters are passed in the registers when calling or being called by other program. And the best source of these convention is in the form of ABI standards defined for each these hardware. For ease of compilation, the same ABI is also used by userspace and kernel program. Linux/Freebsd follow the same ABI for x86-64 and another set for 32-bit. But x86-64 ABI for Windows is different from Linux/FreeBSD. And generally ABI does not differentiate system call vs normal "functions calls". Ie, here is a particular example of x86_64 calling conventions and it is the same for both Linux userspace and kernel: http://eli.thegreenplace.net/2011/09/06/stack-frame-layout-on-x86-64/ (note the sequence a,b,c,d,e,f of parameters):

Performance is one of the reasons for these ABI (eg, passing parameters via registers instead of saving into memory stacks)

For ARM there is various ABI:

This document is good overview of all the different conventions:

If the result is for humans to read and the elements of the array have a proper toString() defined...

outputString.write(Arrays.toString(array));

This solves the issue when you scroll past the beginning or end of the div

var selScrollable = '.scrollable';
// Uses document because document will be topmost level in bubbling
$(document).on('touchmove',function(e){
  e.preventDefault();
});
// Uses body because jQuery on events are called off of the element they are
// added to, so bubbling would not work if we used document instead.
$('body').on('touchstart', selScrollable, function(e) {
  if (e.currentTarget.scrollTop === 0) {
    e.currentTarget.scrollTop = 1;
  } else if (e.currentTarget.scrollHeight === e.currentTarget.scrollTop + e.currentTarget.offsetHeight) {
    e.currentTarget.scrollTop -= 1;
  }
});
// Stops preventDefault from being called on document if it sees a scrollable div
$('body').on('touchmove', selScrollable, function(e) {
  e.stopPropagation();
});

Note that this won't work if you want to block whole page scrolling when a div does not have overflow. To block that, use the following event handler instead of the one immediately above (adapted from this question):

$('body').on('touchmove', selScrollable, function(e) {
    // Only block default if internal div contents are large enough to scroll
    // Warning: scrollHeight support is not universal. (https://stackoverflow.com/a/15033226/40352)
    if($(this)[0].scrollHeight > $(this).innerHeight()) {
        e.stopPropagation();
    }
});

If you don't mind messing with z-index, but you want to avoid adding extra div for overlay, you can use the following approach

/* make sure ::before is positioned relative to .foo */
.foo { position: relative; }

/* overlay */
.foo::before {
    content: '';
    display: block;
    position: absolute;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
    background: rgba(0,0,0,0.5);
    z-index: 0;
}
/* make sure all elements inside .foo placed above overlay element */
.foo > * { z-index: 1; }

I got this error running from VS. Turned out I'd opened a solution without running Visual Studio as admin. Closing Visual studio down and running it again as admin then rebuilding solved this for me.

Hope that helps someone.

In my case, I had all of the required features, but I had installed the Team Explorer version (accidentally used the wrong installer) before installing Professional.

When running the Team Explorer version, only the Blank Solution option was available.

The Team Explorer EXE was located in: "C:\Program Files (x86)\Microsoft Visual Studio\2017\TeamExplorer\Common7\IDE\devenv.exe"

Once I launched the correct EXE, Visual Studio started working as expected.

The Professional EXE was located in: "C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\Common7\IDE\devenv.exe"

This solved my issue, and the reason was I had enterprise edition previously installed and then uninstalled and installed the professional edition. Team Explorer was not modified later when I moved to professional from enterprise edition.

Removing *.snap (mine is *.markers), --clean-data or move workspace folder seems all did not work for me.

As my eclipse stopped working after I installed and switched my keyborad input to HIME, I went back to fctix and it worked.

Here is yet another way without Invoke-Expression but with two variables (command:string and parameters:array). It works fine for me. Assume 7z.exe is in the system path.

$cmd = '7z.exe'
$prm = 'a', '-tzip', 'c:\temp\with space\test1.zip', 'C:\TEMP\with space\changelog'

& $cmd $prm

If the command is known (7z.exe) and only parameters are variable then this will do

$prm = 'a', '-tzip', 'c:\temp\with space\test1.zip', 'C:\TEMP\with space\changelog'

& 7z.exe $prm

BTW, Invoke-Expression with one parameter works for me, too, e.g. this works

$cmd = '& 7z.exe a -tzip "c:\temp\with space\test2.zip" "C:\TEMP\with space\changelog"'

Invoke-Expression $cmd

P.S. I usually prefer the way with a parameter array because it is easier to compose programmatically than to build an expression for Invoke-Expression.
