Notice that this doesn't work in Windows.
The module pxssh does exactly what you want:
For example, to run 'ls -l' and to print the output, you need to do something like that :

from pexpect import pxssh
s = pxssh.pxssh()
if not s.login ('localhost', 'myusername', 'mypassword'):
    print "SSH session failed on login."
    print str(s)
else:
    print "SSH session login successful"
    s.sendline ('ls -l')
    s.prompt()         # match the prompt
    print s.before     # print everything before the prompt.
    s.logout()

I continue to suspect that your customer/user has some kernel module or driver loaded which is interfering with the clone() system call (perhaps some obscure security enhancement, something like LIDS but more obscure?) or is somehow filling up some of the kernel data structures that are necessary for fork()/clone() to operate (process table, page tables, file descriptor tables, etc).

Here's the relevant portion of the fork(2) man page:

ERRORS
       EAGAIN fork() cannot allocate sufficient memory to copy the parent's page tables and allocate a task  structure  for  the
              child.

       EAGAIN It  was not possible to create a new process because the caller's RLIMIT_NPROC resource limit was encountered.  To
              exceed this limit, the process must have either the CAP_SYS_ADMIN or the CAP_SYS_RESOURCE capability.

       ENOMEM fork() failed to allocate the necessary kernel structures because memory is tight.

I suggest having the user try this after booting into a stock, generic kernel and with only a minimal set of modules and drivers loaded (minimum necessary to run your application/script). From there, assuming it works in that configuration, they can perform a binary search between that and the configuration which exhibits the issue. This is standard sysadmin troubleshooting 101.

The relevant line in your strace is:

clone(child_stack=0, flags=CLONE_CHILD_CLEARTID|CLONE_CHILD_SETTID|SIGCHLD, child_tidptr=0xb7f12708) = -1 ENOMEM (Cannot allocate memory)

... I know others have talked about swap and memory availability (and I would recommend that you set up at least a small swap partition, ironically even if it's on a RAM disk ... the code paths through the Linux kernel when it has even a tiny bit of swap available have been exercised far more extensively than those (exception handling paths) in which there is zero swap available.

However I suspect that this is still a red herring.

The fact that free is reporting 0 (ZERO) memory in use by the cache and buffers is very disturbing. I suspect that the free output ... and possibly your application issue here, are caused by some proprietary kernel module which is interfering with the memory allocation in some way.

According to the man pages for fork()/clone() the fork() system call should return EAGAIN if your call would cause a resource limit violation (RLIMIT_NPROC) ... however, it doesn't say if EAGAIN is to be returned by other RLIMIT* violations. In any event if your target/host has some sort of weird Vormetric or other security settings (or even if your process is running under some weird SELinux policy) then it might be causing this -ENOMEM failure.

It's pretty unlikely to be a normal run-of-the-mill Linux/UNIX issue. You've got something non-standard going on there.

The simple solution is to avoid creating an array before piping to Out-File. Rule #1 of PowerShell is that the comma is a special delimiter, and the default behavior is to create an array. Concatenation is done like this.

$computer + "," + $Speed + "," + $Regcheck | out-file -filepath C:\temp\scripts\pshell\dump.txt -append -width 200

This creates an array of three items.

$computer,$Speed,$Regcheck
FYKJ
100
YES

vs. concatenation of three items separated by commas.

$computer + "," + $Speed + "," + $Regcheck
FYKJ,100,YES

If you are having a problem with the font working I have also had this in the past and the issue I found was down to the font-family: name. This had to match what font name was actually given.

The easiest way I found to find this out was to install the font and see what display name is given.

For example, I was using Gill Sans on one project, but the actual font was called Gill Sans MT. Spacing and capitlisation was also important to get right.

Hope that helps.

Try setting the "endOfLine":"auto" in your .prettierrc file (inside the object)

Or set

"prettier/prettier": ["error", {
     ..
    "endOfLine":"auto"
     ..
  }],

inside the rules object of the eslintrc file.

If you are using windows machine endOfLine can be "crlf" basing on your git config.

If you need check ranges you are probably better off with if and else if statements, like so:

if (range > 0 && range < 5)
{
    // ..
}
else if (range > 5 && range < 9)
{
    // ..
}
else
{
    // Fall through
}

A switch could get large on bigger ranges.

You are looking for

MyList.Select(x=>x.Name).ToArray();

Since Select is an Extension method make sure to add that namespace by adding a

using System.Linq

to your file - then it will show up with Intellisense.

What

 l.onclick();

does is exactly calling the onclick function of l, that is, if you have set one with l.onclick = myFunction;. If you haven't set l.onclick, it does nothing. In contrast,

 l.click();

simulates a click and fires all event handlers, whether added with l.addEventHandler('click', myFunction);, in HTML, or in any other way.

From the jQuery documentation:

As of jQuery 1.7, the .on() method is the preferred method for attaching event handlers to a document. For earlier versions, the .bind() method is used for attaching an event handler directly to elements. Handlers are attached to the currently selected elements in the jQuery object, so those elements must exist at the point the call to .bind() occurs. For more flexible event binding, see the discussion of event delegation in .on() or .delegate().

http://api.jquery.com/bind/

In JAVA, values like:

1. 8.5
2. 3.9
3. (and so on..)

Is assumed as double and not float.

You can also perform a cast in order to solve the problem:

float b = (float) 3.5;

Another solution:

float b = 3.5f;

This is resolve my case as found on Where to find the win32api module for Python?

pip install pypiwin32

I know this is an old thread, but has anyone checked if their Antivirus is blocking Win32API and Scripting on their systems? I have CylanceProtect installed on my office system and i found the same issues occurring as listed by others. This can be confirmed if you check the Windows Logs in Event Viewer.

I need help to adjust my script below or to find a script that could be used on my wordpress site to grab the url suffix parameters from a forward url, then to be added at the button click url for tracking the proper forward ads id.

REASON: parameters are used for advertisement tracking to find out from which ad the user has been forward, even if the user hops from optin page to the sales page by using button click.

Here the goal to reach: 1. An FB ad points to an optin page with tracking code: https://ownsite.com/optin-page/?tid=fbad1 2. At the optin-page there is a button with a setup URL to forward to the sales page, but if clicked then only the URL is forward, but the parameter "?tid=fbad1" is missing. 3. The auto-forward script below (which is working properly) can be used to change for button click forward, but has a limitation as it grab only "tid" parameters instead also utm parameters.

Therefore a script code shall be implemented to establish click buttons (also to style them or use images instead) and while clicking the button to forward to a different sales page with grabbing the suffix parameter form the current optin-page to forward then to sales-page https://ownsite.com/sales-page/?tid=fbad1 also including UTM parameters

Currently, I could have solved this by using an auto-redirect script, but A.) I do not want to use an autoredirect at this page. Better is an event click button used to let the user himself click to forward with the URL parameter included. B.) The tracking ID parameter in this script is limited to "?tid=..." instead I do also want to track the UTM code on button click also i.e. Grab from current page the paramater of URL https://www.optin-page.com/?tid=facebookad1?utm_campaign=blogpost then on button click grab parameters and add to button set URL https://www.sales-page.com/?tid=facebookad1?utm_campaign=blogpost

Please now find here the Code below in use for auto-redirect and grabbing the URL parameters. This code shall be changed now to be able to create a button with a click-event to be redirect then to the forward URL with parameter grabbing of current URL if the button is clicked (as stated above).

Not as such. One method is to send the appropriate headers when delivering content to force the browser to reload:

Making sure a web page is not cached, across all browsers.

If your search for "cache header" or something similar here on SO, you'll find ASP.NET specific examples.

Another, less clean but sometimes only way if you can't control the headers on server side, is adding a random GET parameter to the resource that is being called:

myimage.gif?random=1923849839

\d+

\d represents any digit, + for one or more. If you want to catch negative numbers as well you can use -?\d+.

Note that as a string, it should be represented in C# as "\\d+", or @"\d+"

I ran into this same issue trying to install the dbf package in Python 2.7. The problem is that the enum package wasn't added to Python until version 3.4.

It has been backported to versions 3.3, 3.2, 3.1, 2.7, 2.6, 2.5, and 2.4, you just need the package from here: https://pypi.python.org/pypi/enum34#downloads

Answer to Question 1

Here's what I did on a Ubuntu EC2:

A) Login as root using the keypairs

B) Setup the necessary users and their passwords with

# sudo adduser USERNAME
# sudo passwd USERNAME

C) Edit /etc/ssh/sshd_config setting

For a valid user to login with no key

PasswordAuthentication yes

Also want root to login also with no key

PermitRootLogin yes

D) Restart the ssh daemon with

# sudo service ssh restart

just change ssh to sshd if you are using centOS

Now you can login into your ec2 instance without key pairs.

See the thumbnail function of PIL's Image Module. You can use it to save smaller versions of files as various filetypes and if you're wanting to preserve as much quality as you can, consider using the ANTIALIAS filter when you do.

Other than that, I'm not sure if there's a way to specify a maximum desired size. You could, of course, write a function that might try saving multiple versions of the file at varying qualities until a certain size is met, discarding the rest and giving you the image you wanted.

I think you want SELECT * FROM INFORMATION_SCHEMA.TABLES

See http://dev.mysql.com/doc/refman/5.0/en/tables-table.html

If you want a true onChangedListener(). Store the initial value in the handler and check to see if it has changed. It is simple and does not require a global variable. Works if you have more than one spinner on the page.

String initialValue = // get from Database or your object
mySpinner.setOnItemSelectedListener(new SpinnerSelectedListener(initialValue));

...

protected class SpinnerSelectedListener implements AdapterView.OnItemSelectedListener {

        private SpinnerSelectedListener() {
            super();
        }

        public SpinnerSelectedListener(String initialValue) {
            this();
            this.initialValue = initialValue;
        }

        private String initialValue;

        // getter and setter removed.  

        @Override
        public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
            final String newValue = (String) spinHeight.getItemAtPosition(position);
            if (newValue.equals(initialValue) == false) {
               // Add your code here.  The spinner has changed value. 

               // Maybe useful.   
               // initialValue = newValue;
            }

        }

        @Override
        public void onNothingSelected(AdapterView<?> parent) {
               // Maybe useful.   
               // initialValue = null; 
        }
    }

Objects are your friend, use them.

The simplest approach would be to use LINQ:

var count = text.TakeWhile(c => c == '$').Count();

There are certainly more efficient approaches, but that's probably the simplest.

Too bad Oracle has limitations like these. Sure, the result for a column not in the GROUP BY would be random, but sometimes you want that. Silly Oracle, you can do this in MySQL/MSSQL.

BUT there is a work around for Oracle:

While the following line does not work

SELECT unique_id_col, COUNT(1) AS cnt FROM yourTable GROUP BY col_A;

You can trick Oracle with some 0's like the following, to keep your column in scope, but not group by it (assuming these are numbers, otherwise use CONCAT)

SELECT MAX(unique_id_col) AS unique_id_col, COUNT(1) AS cnt 
FROM yourTable GROUP BY col_A, (unique_id_col*0 + col_A);

Break out the LIKE clauses into 2 separate statements, i.e.:

(fieldname1 LIKE '%this%' or fieldname1 LIKE '%that%' ) and something=else

<html>
<head>
<script language="javascript" type="text/javascript" scr="asd.js"></script>
</head>

<body>

<form name="form1" action="#" method="get">
name:<input type ="text" id="name" name="n">
<input type="submit" value="next" >
<button type="button" id="print" onClick="testJS()"> Print </button>
</form>

</body>

client side scripting

function testJS(){
var name = jQuery("#name").val();
jQuery.load("next.html",function(){
jQuery("#here").html(name);
});
}

jQuery is a js library and it simplifies its programming. So I recommend to use jQuery rathar then js. Here I just took value of input elemnt(id = name) on submit button click event ,then loaded the desired page(next.html), if the load function executes successfully i am calling a function which will put the data in desired place.

Action method needs to return FileResult with either a stream, byte[], or virtual path of the file. You will also need to know the content-type of the file being downloaded. Here is a sample (quick/dirty) utility method. Sample video link How to download files using asp.net core

[Route("api/[controller]")]
public class DownloadController : Controller
{
    [HttpGet]
    public async Task<IActionResult> Download()
    {
        var path = @"C:\Vetrivel\winforms.png";
        var memory = new MemoryStream();
        using (var stream = new FileStream(path, FileMode.Open))
        {
            await stream.CopyToAsync(memory);
        }
        memory.Position = 0;
        var ext = Path.GetExtension(path).ToLowerInvariant();
        return File(memory, GetMimeTypes()[ext], Path.GetFileName(path));
    }

    private Dictionary<string, string> GetMimeTypes()

    }
}

use of onScroll enters infinite loop. onMomentumScrollEnd or onScrollEndDrag can be used instead

I would like to add a standard library option (i.e. cross-platform) how to generate exception backtraces, which has become available with C++11:

Use std::nested_exception and std::throw_with_nested

This won't give you a stack unwind, but in my opinion the next best thing. It is described on StackOverflow here and here, how you can get a backtrace on your exceptions inside your code without need for a debugger or cumbersome logging, by simply writing a proper exception handler which will rethrow nested exceptions.

Since you can do this with any derived exception class, you can add a lot of information to such a backtrace! You may also take a look at my MWE on GitHub, where a backtrace would look something like this:

Library API: Exception caught in function 'api_function'
Backtrace:
~/Git/mwe-cpp-exception/src/detail/Library.cpp:17 : library_function failed
~/Git/mwe-cpp-exception/src/detail/Library.cpp:13 : could not open file "nonexistent.txt"

Well we don't actually need inspect here.

>>> func = lambda x, y: (x, y)

...  print(func2.__code__.co_varnames)
...  pass # Other things

For Python 2.5 and older, use func_code instead of __code__, and func_defaults instead of __defaults__.

Some of the tutorials I found that are easy to understand are:

• http://www.phpfreaks.com/tutorial/basic-pagination

It makes way more sense to break up your list into page-sized chunks, and only query your database one chunk at a time. This drastically reduces server processing time and page load time, as well as gives your user smaller pieces of info to digest, so he doesn't choke on whatever crap you're trying to feed him. The act of doing this is called pagination.

A basic pagination routine seems long and scary at first, but once you close your eyes, take a deep breath, and look at each piece of the script individually, you will find it's actually pretty easy stuff

The script:

// find out how many rows are in the table 
$sql = "SELECT COUNT(*) FROM numbers";
$result = mysql_query($sql, $conn) or trigger_error("SQL", E_USER_ERROR);
$r = mysql_fetch_row($result);
$numrows = $r[0];

// number of rows to show per page
$rowsperpage = 10;
// find out total pages
$totalpages = ceil($numrows / $rowsperpage);

// get the current page or set a default
if (isset($_GET['currentpage']) && is_numeric($_GET['currentpage'])) {
   // cast var as int
   $currentpage = (int) $_GET['currentpage'];
} else {
   // default page num
   $currentpage = 1;
} // end if

// if current page is greater than total pages...
if ($currentpage > $totalpages) {
   // set current page to last page
   $currentpage = $totalpages;
} // end if
// if current page is less than first page...
if ($currentpage < 1) {
   // set current page to first page
   $currentpage = 1;
} // end if

// the offset of the list, based on current page 
$offset = ($currentpage - 1) * $rowsperpage;

// get the info from the db 
$sql = "SELECT id, number FROM numbers LIMIT $offset, $rowsperpage";
$result = mysql_query($sql, $conn) or trigger_error("SQL", E_USER_ERROR);

// while there are rows to be fetched...
while ($list = mysql_fetch_assoc($result)) {
   // echo data
   echo $list['id'] . " : " . $list['number'] . "<br />";
} // end while

/******  build the pagination links ******/
// range of num links to show
$range = 3;

// if not on page 1, don't show back links
if ($currentpage > 1) {
   // show << link to go back to page 1
   echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=1'><<</a> ";
   // get previous page num
   $prevpage = $currentpage - 1;
   // show < link to go back to 1 page
   echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=$prevpage'><</a> ";
} // end if 

// loop to show links to range of pages around current page
for ($x = ($currentpage - $range); $x < (($currentpage + $range) + 1); $x++) {
   // if it's a valid page number...
   if (($x > 0) && ($x <= $totalpages)) {
      // if we're on current page...
      if ($x == $currentpage) {
         // 'highlight' it but don't make a link
         echo " [<b>$x</b>] ";
      // if not current page...
      } else {
         // make it a link
         echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=$x'>$x</a> ";
      } // end else
   } // end if 
} // end for

// if not on last page, show forward and last page links        
if ($currentpage != $totalpages) {
   // get next page
   $nextpage = $currentpage + 1;
    // echo forward link for next page 
   echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=$nextpage'>></a> ";
   // echo forward link for lastpage
   echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=$totalpages'>>></a> ";
} // end if
/****** end build pagination links ******/
?>

This tutorial is intended for developers who wish to give their users the ability to step through a large number of database rows in manageable chunks instead of the whole lot in one go.

Another tactic not yet mentioned is using appending to a list, and then converting the list to a tuple at the end:

mylist = []
for x in range(5):
    mylist.append(x)
mytuple = tuple(mylist)
print mytuple

returns

(0, 1, 2, 3, 4)

I sometimes use this when I have to pass a tuple as a function argument, which is often necessary for the numpy functions.

you can restrict the no of thread uses from scheduler as well as put timeout on the task.

If the solutions proposed here aren't working for you, and your image asset is actually a PDF, note that XCode actually treats PDFs differently than image files. In particular, it doesn't seem able to scale to fill properly with a PDF: it ends up tiled instead. This drove me crazy until I figured out that the issue was the PDF format. Convert to JPG and you should be good to go.

You can either abort the merge step:

git merge --abort

else you can keep your changes (on which branch you are)

git checkout --ours file1 file2 ...

otherwise you can keep other branch changes

git checkout --theirs file1 file2 ...

From matplotlib version 2.1 onwards, you may use a figure legend. Instead of ax.legend(), which produces a legend with the handles from the axes ax, one can create a figure legend

fig.legend(loc="upper right")

which will gather all handles from all subplots in the figure. Since it is a figure legend, it will be placed at the corner of the figure, and the loc argument is relative to the figure.

import numpy as np
import matplotlib.pyplot as plt

x = np.linspace(0,10)
y = np.linspace(0,10)
z = np.sin(x/3)**2*98

fig = plt.figure()
ax = fig.add_subplot(111)
ax.plot(x,y, '-', label = 'Quantity 1')

ax2 = ax.twinx()
ax2.plot(x,z, '-r', label = 'Quantity 2')
fig.legend(loc="upper right")

ax.set_xlabel("x [units]")
ax.set_ylabel(r"Quantity 1")
ax2.set_ylabel(r"Quantity 2")

plt.show()

In order to place the legend back into the axes, one would supply a bbox_to_anchor and a bbox_transform. The latter would be the axes transform of the axes the legend should reside in. The former may be the coordinates of the edge defined by loc given in axes coordinates.

fig.legend(loc="upper right", bbox_to_anchor=(1,1), bbox_transform=ax.transAxes)

If anyone comes here after me, this is the answer that worked for me.

NOTE: please make to read the comments before using this, this not complete. The best advice for update queries I can give is to switch to SqlServer ;)

update mytable t
set z = (
  with comp as (
    select b.*, 42 as computed 
    from mytable t 
    where bs_id = 1
  )
  select c.computed
  from  comp c
  where c.id = t.id
)

Good luck,

Use:

yourdataView.AutoResizeColumns(DataGridViewAutoSizeColumnsMode.AllCells);

This error happened to me in a Grails Application with the JTDS Driver 1.3.0 (SQL Server). The problem was an incorrect login in SQL Server. After solve this issue (in SQL Server) my app was correctly deployed in Tomcat. Tip: I saw the error in stacktrace.log

Whenever a TypeInitializationException is thrown, check all initialization logic of the type you are referring to for the first time in the statement where the exception is thrown - in your case: Logger.

Initialization logic includes: the type's static constructor (which - if I didn't miss it - you do not have for Logger) and field initialization.

Field initialization is pretty much "uncritical" in Logger except for the following lines:

private static string s_bstCommonAppData = Path.Combine(s_commonAppData, "XXXX");
private static string s_bstUserDataDir = Path.Combine(s_bstCommonAppData, "UserData");
private static string s_commonAppData = Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData);

s_commonAppData is null at the point where Path.Combine(s_commonAppData, "XXXX"); is called. As far as I'm concerned, these initializations happen in the exact order you wrote them - so put s_commonAppData up by at least two lines ;)

Here is good example of the CRUD operation using fetch API:

“A practical ES6 guide on how to perform HTTP requests using the Fetch API” by Dler Ari https://link.medium.com/4ZvwCordCW

Here is the sample code I tried for PATCH or PUT

function update(id, data){
  fetch(apiUrl + "/" + id, {
    method: 'PATCH',
    body: JSON.stringify({
     data
    })
  }).then((response) => {
    response.json().then((response) => {
      console.log(response);
    })
  }).catch(err => {
    console.error(err)
  })

For DELETE:

function remove(id){
  fetch(apiUrl + "/" + id, {
    method: 'DELETE'
  }).then(() => {
     console.log('removed');
  }).catch(err => {
    console.error(err)
  });

For more info visit Using Fetch - Web APIs | MDN https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API/Using_Fetch > Fetch_API.

My Solution

User.find()
        .exec()
        .then(users => {
            const response = {
                count: users.length,
                users: users.map(user => {

                    return {
                        _id: user._id,
                        // other property
                    }

                })

            };
            res.status(200).json(response);
        }).catch(err => {
        console.log(err);
        res.status(500).json({
            success: false
        })
    })

Here's a simple-and-stupid approach: on input, discretize your polygons into a bitmap. To intersect, AND the bitmaps together. To produce output polygons, trace out the jaggy borders of the bitmap and smooth the jaggies using a polygon-approximation algorithm. (I don't remember if that link gives the most suitable algorithms, it's just the first Google hit. You might check out one of the tools out there to convert bitmap images to vector representations. Maybe you could call on them without reimplementing the algorithm?)

The most complex part would be tracing out the borders, I think.

Back in the early 90s I faced something like this problem at work, by the way. I muffed it: I came up with a (completely different) algorithm that would work on real-number coordinates, but seemed to run into a completely unfixable plethora of degenerate cases in the face of the realities of floating-point (and noisy input). Perhaps with the help of the internet I'd have done better!

Try:

android:layout_height="wrap_content"
android:scaleType="fitStart"

on the image in the RelativeLayout

Most of you already know this by now, but I am posting this, just incase, some of you are still struggling with JSON in iOS6+.

In iOS6 and later, we have the NSJSONSerialization Class that is fast and has no dependency on including "outside" libraries.

NSDictionary *result = [NSJSONSerialization JSONObjectWithData:[resultStr dataUsingEncoding:NSUTF8StringEncoding] options:0 error:nil]; 

This is the way iOS6 and later can now parse JSON efficiently.The use of SBJson is also pre-ARC implementation and brings with it those issues too if you are working in an ARC environment.

I hope this helps!

Firstly, you start Activities and Services with an intent, you start fragments with fragment transactions. Secondly, your transaction isnt doing anything. Change it to something like:

FragmentTransaction transaction = getFragmentManager();
    transaction.beginTransaction()
        .replace(R.layout.container, newFragment) //<---replace a view in your layout (id: container) with the newFragment 
        .commit();

It's probably because asterisk is not running on your server.

Try to run it with this command :

asterisk -vvvvvvc

You'll enter into the Asterisk CLI and if something goes wrong you'll see it. After that you can quit the CLI by entering the exit command. Then you can reconnect to the CLI by typing asterisk -r. All this commands assumed you're the root user. If you are not root prefix them by sudo, by example sudo asterisk -vvvvvvc.

Hope it helps, regards, Duc.

This is my solution which perfectly works starting from API 15. This solution keeps all default button click effects, like material RippleEffect. I have not tested it on lower APIs, but it should work.

All you need to do, is:

1) Create a style which changes only colorAccent:

<style name="Facebook.Button" parent="ThemeOverlay.AppCompat">
    <item name="colorAccent">@color/com_facebook_blue</item>
</style>

I recommend using ThemeOverlay.AppCompat or your main AppTheme as parent, to keep the rest of your styles.

2) Add these two lines to your button widget:

style="@style/Widget.AppCompat.Button.Colored"
android:theme="@style/Facebook.Button"

Sometimes your new colorAccent isn't showing in Android Studio Preview, but when you launch your app on the phone, the color will be changed.

Sample Button widget

<Button
    android:id="@+id/sign_in_with_facebook"
    style="@style/Widget.AppCompat.Button.Colored"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:text="@string/sign_in_facebook"
    android:textColor="@android:color/white"
    android:theme="@style/Facebook.Button" />

Similar approach to @Samuel-bergström:

• Download Fontawesome SVG https://github.com/FortAwesome/Font-Awesome/blob/master/src/assets/font-awesome/fonts/fontawesome-webfont.svg
• Download FontForge http://fontforge.github.io/en-US/downloads/
• Download Inkscape
• Open Inskscape and create a single layer shape as your new font icon
• Save SVG file, Close Inkscape
• Open FontForge (If you have multiple monitors, use Windows-LeftArrow, to reposition as they have strange SWING java windows that go off monitor, and have modal problems with popups - I had to check my task bar for some)
• File | Open fontawesome-webfont.svg
• File | Import
• Scroll to the bottom, Right Click on Icon | Glyph Info
• Update Glyph Name to uniFXXX (XXX is something like 501, a higher number than the highest Unicode used in v4.5 of FontAwesome)
• Unicode Vlaue U+fXXX
• Click OK
• File | Save
• File | Generate Fonts ...
• Close FontForge
• Open your web project
• Copy your font files to the (in my project) "\Content\fonts\" folder.
• Edit "\Content\styles\fa\path.less" to be like:

@font-face {_x000D_
      font-family: 'FontAwesome';_x000D_
      //src: url('@{fa-font-path}/fontawesome-webfont.eot?v=@{fa-version}');_x000D_

      font-weight: normal;_x000D_
      font-style: normal;_x000D_
    }

I know it may be 'controversial' to comment out other file types, but happy to hear how to generate .eot or .otf files in the comments.

• and finally, as Samuel mentions, update your CSS/LESS with:

  .fa-XXX:before { content: "\f501"; }

Here is how to to that:

The header and footer are 30px height.

The footer is stuck to the bottom of the page.

HTML:

<div id="header">
</div>
<div id="content">
</div>
<div id="footer">
</div>

CSS:

#header {
    height: 30px;
}
#footer {
    height: 30px;
    position: absolute;
    bottom: 0;
}
body {
    height: 100%;
    margin-bottom: 30px;
}

To obtain a const char * from an std::string use the c_str() member function :

std::string str = "string";
const char* chr = str.c_str();

To obtain a non-const char * from an std::string you can use the data() member function which returns a non-const pointer since C++17 :

std::string str = "string";
char* chr = str.data();

For older versions of the language, you can use range construction to copy the string into a vector from which a non-const pointer can be obtained :

std::string str = "string";
std::vector<char> str_copy(str.c_str(), str.c_str() + str.size() + 1);
char* chr = str_copy.data();

But beware that this won't let you modify the string contained in str, only the copy's data can be changed this way. Note that it's specially important in older versions of the language to use c_str() here because back then std::string wasn't guaranteed to be null terminated until c_str() was called.

When you need padding inside the JPanel generally you add padding with the layout manager you are using. There are cases that you can just expand the border of the JPanel.

Don't use rows.Count. That's asking for how many rows exist. If there are many, it will take some time to count them. All you really want to know is "is there at least one?" You don't care if there are 10 or 1000 or a billion. You just want to know if there is at least one. If I give you a box and ask you if there are any marbles in it, will you dump the box on the table and start counting? Of course not. Using LINQ, you might think that this would work:

bool hasRows = dataTable1.Rows.Any()

But unfortunately, DataRowCollection does not implement IEnumerable. So instead, try this:

bool hasRows = dataTable1.Rows.GetEnumerator().MoveNext()

You will of course need to check if the dataTable1 is null first. if it's not, this will tell you if there are any rows without enumerating the whole lot.

I am not going to give you the whole answer (I don't think you're looking for the parsing and writing to file part anyway), but a pivotal hint should suffice: use python's set() function, and then sorted() or .sort() coupled with .reverse():

>>> a=sorted(set([10,60,30,10,50,20,60,50,60,10,30]))
>>> a
[10, 20, 30, 50, 60]
>>> a.reverse()
>>> a
[60, 50, 30, 20, 10]

You could use a CSS pre-processor to do your skinning. With Sass you can do something similar to this:

_theme1.scss:

$theme-primary-color: #a00;
$theme-secondary-color: #d00;
// etc.

_theme2.scss:

$theme-primary-color: #666;
$theme-secondary-color: #ccc;
// etc.

styles.scss:

// import whichever theme you want to use
@import 'theme2';

-webkit-box-shadow: inset 0px 0px 2px $theme-primary-color;
-moz-box-shadow: inset 0px 0px 2px $theme-primary-color;

If it's not site wide theming but class based theming you need, then you can do this: http://codepen.io/jjenzz/pen/EaAzo

To those still having problems, I solved it this way:

List<Item> newItems = databaseHandler.getItems();
ListArrayAdapter.clear();
ListArrayAdapter.addAll(newItems);
ListArrayAdapter.notifyDataSetChanged();
databaseHandler.close();

I first cleared the data from the adapter, then added the new collection of items, and only then set notifyDataSetChanged(); This was not clear for me at first, so I wanted to point this out. Take note that without calling notifyDataSetChanged() the view won't be updated.

You can't. IEnumerable<T> can only be iterated.

In your second example, you can remove from original collection by iterating over a copy of it

foreach(var u in users.ToArray()) // ToArray creates a copy
{
   if(u.userId != 1233)
   {
        users.Remove(u);
   }
}

For your Q2, there are already answers to your question. For your Q1, and more generally when you know that the key's filtering should give a unique value, there's no need to use Streams at all.

Just use get or getOrDefault, i.e:

List<String> list1 = id1.getOrDefault(1, Collections.emptyList());

I took some help from MSDN, but this is my answer:

double number;
string localStringNumber;
string doubleNumericValueasString = "65.89875";
System.Globalization.NumberStyles style = System.Globalization.NumberStyles.AllowDecimalPoint;

if (double.TryParse(doubleNumericValueasString, style, System.Globalization.CultureInfo.InvariantCulture, out number))
    Console.WriteLine("Converted '{0}' to {1}.", doubleNumericValueasString, number);
else
    Console.WriteLine("Unable to convert '{0}'.", doubleNumericValueasString);
localStringNumber =number.ToString(System.Globalization.CultureInfo.CreateSpecificCulture("de-DE"));

if you want to do very quick plots with secondary Y-Axis then there is much easier way using Pandas wrapper function and just 2 lines of code. Just plot your first column then plot the second but with parameter secondary_y=True, like this:

df.A.plot(label="Points", legend=True)
df.B.plot(secondary_y=True, label="Comments", legend=True)

This would look something like below:

You can do few more things as well. Take a look at Pandas plotting doc.

Simple! The folder named .. is the parent folder, so you can make the path to the file you need as such

var foobar = require('../config/dev/foobar.json');

On your existing button code, simply insert this line before the procedure:

If MsgBox("This will erase everything! Are you sure?", vbYesNo) = vbNo Then Exit Sub

In short, The basic problem an interface is trying to solve is to separate how we use something from how it is implemented. But you should consider interface is not a contract. Read more here.

Sounds like you need to change the path to your java executable to match the newest version. Basically, installing the latest Java does not necessarily mean your machine is configured to use the latest version. You didn't mention any platform details, so that's all I can say.

Use ClassLoader.getResource() to find the URL for your current class.

For example:

package foo;

public class Test
{
    public static void main(String[] args)
    {
        ClassLoader loader = Test.class.getClassLoader();
        System.out.println(loader.getResource("foo/Test.class"));
    }
}

(This example taken from a similar question.)

To find the directory, you'd then need to take apart the URL manually. See the JarClassLoader tutorial for the format of a jar URL.

Right below the RewriteEngine On line, add:

RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)/$ /$1 [L,R] # <- for test, for prod use [L,R=301]

to enforce a no-trailing-slash policy.

To enforce a trailing-slash policy:

RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*[^/])$ /$1/ [L,R] # <- for test, for prod use [L,R=301]

EDIT: commented the R=301 parts because, as explained in a comment:

Be careful with that R=301! Having it there makes many browsers cache the .htaccess-file indefinitely: It somehow becomes irreversible if you can't clear the browser-cache on all machines that opened it. When testing, better go with simple R or R=302

After you've completed your tests, you can use R=301.

To temporarily set an environment variable without having to copy the os.envrion object etc, I do this:

process = subprocess.Popen(['env', 'RSYNC_PASSWORD=foobar', 'rsync', \
'rsync://[email protected]::'], stdout=subprocess.PIPE)

The idea that you need to get the reference to the object that is contained inside a Set object is common. It can be archived by 2 ways:

1. Use HashSet as you wanted, then:

   public Object getObjectReference(HashSet<Xobject> set, Xobject obj) {
       if (set.contains(obj)) {
           for (Xobject o : set) {
               if (obj.equals(o))
                   return o;
           }
       }
       return null;
   }
   

For this approach to work, you need to override both hashCode() and equals(Object o) methods In the worst scenario we have O(n)

2. Second approach is to use TreeSet

   public Object getObjectReference(TreeSet<Xobject> set, Xobject obj) {
       if (set.contains(obj)) {
           return set.floor(obj);
       }
       return null;
   }
   

This approach gives O(log(n)), more efficient. You don't need to override hashCode for this approach but you have to implement Comparable interface. ( define function compareTo(Object o)).

You must have an empty line in your file.

You may want to wrap your parseInt calls in a "try" block:

try {
  tall[i++] = Integer.parseInt(s);
}
catch (NumberFormatException ex) {
  continue;
}

Or simply check for empty strings before parsing:

if (s.length() == 0) 
  continue;

Note that by initializing your index variable i inside the loop, it is always 0. You should move the declaration before the while loop. (Or make it part of a for loop.)

The other answer is very complete, but here is a rule of thumb:

• call is blocking:

  call('notepad.exe')
  print('hello')  # only executed when notepad is closed
  

• Popen is non-blocking:

  Popen('notepad.exe')
  print('hello')  # immediately executed

I'm surprised no one has mentioned dnSpy. dnSpy is a debugger and .NET assembly editor. You can use it to edit and debug assemblies even if you don't have any source code available.

Main features:

• Debug .NET and Unity assemblies
• Edit .NET and Unity assemblies
• Light and dark themes

It is open source and one of most widely used reverse engineering tool for dot net.

In Your example, apache.yml is tasklist, but not playbook

In depends on desired architecture, You can do one of:

1. Convert apache.yml to role. Then define tasks in roles/apache/tasks/mail.yml and variables in roles/apache/defaults/mail.yml (vars in defaults can be overriden when role applied)

2. Set vars in play.yml playbook

play.yml

---
- hosts: 127.0.0.1
  connection: local
  sudo: false

  vars:
    url: czxcxz

  tasks:
     - include: apache.yml

apache.yml

- name: Download apache
  shell: wget {{url}} 

You'd have to define alphanumerics exactly, but

/^(\w{3,5})$/ 

Should match any digit/character/_ combination of length 3-5.

If you also need the dash, make sure to escape it (\-) add it, like this: :

/^([\w\-]{3,5})$/ 

Also: the ^ anchor means that the sequence has to start at the beginning of the line (character string), and the $ that it ends at the end of the line (character string). So your value string mustn't contain anything else, or it won't match.

You just need to put -y with the install command.

For example: yum install <package_to_install> -y

Since cP/WHM took away the ability to modify User privileges as root in PHPMyAdmin, you have to use the command line to:

mysql>  GRANT FILE ON *.* TO 'user'@'localhost';

Step 2 is to allow that user to dump a file in a specific folder. There are a few ways to do this but I ended up putting a folder in :

/home/user/tmp/db

and

chown mysql:mysql /home/user/tmp/db

That allows the mysql user to write the file. As previous posters have said, you can use the MySQL temp folder too, I don't suppose it really matters but you definitely don't want to make it 0777 permission (world-writeable) unless you want the world to see your data. There is a potential problem if you want to rinse-repeat the process as INTO OUTFILE won't work if the file exists. If your files are owned by a different user then just trying to unlink($file) won't work. If you're like me (paranoid about 0777) then you can set your target directory using:

chmod($dir,0777)

just prior to doing the SQL command, then

chmod($dir,0755)

immediately after, followed by unlink(file) to delete the file. This keeps it all running under your web user and no need to invoke the mysql user.

So, let me give you sample code:

<div class="news">
Blah, blah, blah. I'm hidden.
</div>

<a class="trigger">Hide/Show News</a>

The link will be the trigger to show the div when clicked. So your Javascript will be:

$('.trigger').click(function() {
   $('.news').toggle();
});

You're almost always better off letting jQuery handle the styling for hiding and showing elements.

Edit: I see people above are recommending using .show and .hide for this. .toggle allows you to do both with just one effect. So that's cool.

You have to placed this code in application.rb

config.action_dispatch.default_headers = {
        'Access-Control-Allow-Origin' => '*',
        'Access-Control-Request-Method' => %w{GET POST OPTIONS}.join(",")
}

The Pympler package's asizeof module can do this.

Use as follows:

from pympler import asizeof
asizeof.asizeof(my_object)

Unlike sys.getsizeof, it works for your self-created objects. It even works with numpy.

>>> asizeof.asizeof(tuple('bcd'))
200
>>> asizeof.asizeof({'foo': 'bar', 'baz': 'bar'})
400
>>> asizeof.asizeof({})
280
>>> asizeof.asizeof({'foo':'bar'})
360
>>> asizeof.asizeof('foo')
40
>>> asizeof.asizeof(Bar())
352
>>> asizeof.asizeof(Bar().__dict__)
280
>>> A = rand(10)
>>> B = rand(10000)
>>> asizeof.asizeof(A)
176
>>> asizeof.asizeof(B)
80096

As mentioned,

The (byte)code size of objects like classes, functions, methods, modules, etc. can be included by setting option code=True.

And if you need other view on live data, Pympler's

module muppy is used for on-line monitoring of a Python application and module Class Tracker provides off-line analysis of the lifetime of selected Python objects.

Pointer-events is a Mozilla hack and where it has been implemented in Webkit browsers, you can't expect to see it in IE browsers for another million years.

There is however a solution I found:

Forwarding Mouse Events Through Layers

This uses a plugin that uses some not well known/understood properties of Javascript to take the mouse event and send it to another element.

There is also another Javascript solution here.

Update for October 2013: apparently it's coming to IE in v11. Source. Thanks Tim.

If you use docker in your dev you can do this in another shell: docker attach running_node_app_container_name

That will show you STDOUT and STDERR.

How I did this in Swift (including the string formatting to show it as "01:23"):

let totalSeconds: Double = someTimeInterval
let minutes = Int(floor(totalSeconds / 60))
let seconds = Int(round(totalSeconds % 60))        
let timeString = String(format: "%02d:%02d", minutes, seconds)
NSLog(timeString)

Do Shift+F5 in Windows. The cache really frustrates in this kind of stuff

This is my solution:

File f = new File("file.txt");
if(f.exists() && !f.isDirectory()) { 
    f.delete();
}

Better one line solution:

var answerInt = [];
var answerString = "1 2 3 4";
answerString.split(' ').forEach(function (item) {
   answerInt.push(parseInt(item))
});

Basically, an integer n is a power of three, if there exists an integer x such that n == 3x.

So to verify that you can use this functions

def is_power_of_three(n)
  return false unless n.positive?

  n == 3**(Math.log10(n)/Math.log10(3)).to_f.round(2)
end

Entity interface

public interface Entity<I> extends Serializable {

/**
 * @return entity identity
 */
I getId();

/**
 * @return HashCode of entity identity
 */
int identityHashCode();

/**
 * @param other
 *            Other entity
 * @return true if identities of entities are equal
 */
boolean identityEquals(Entity<?> other);
}

Basic implementation for all Entities, simplifies Equals/Hashcode implementations:

public abstract class AbstractEntity<I> implements Entity<I> {

@Override
public final boolean identityEquals(Entity<?> other) {
    if (getId() == null) {
        return false;
    }
    return getId().equals(other.getId());
}

@Override
public final int identityHashCode() {
    return new HashCodeBuilder().append(this.getId()).toHashCode();
}

@Override
public final int hashCode() {
    return identityHashCode();
}

@Override
public final boolean equals(final Object o) {
    if (this == o) {
        return true;
    }
    if ((o == null) || (getClass() != o.getClass())) {
        return false;
    }

    return identityEquals((Entity<?>) o);
}

@Override
public String toString() {
    return getClass().getSimpleName() + ": " + identity();
    // OR 
    // return ReflectionToStringBuilder.reflectionToString(this, ToStringStyle.MULTI_LINE_STYLE);
}
}

Room Entity impl:

@Entity
@Table(name = "ROOM")
public class Room extends AbstractEntity<Integer> {

private static final long serialVersionUID = 1L;

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "room_id")
private Integer id;

@Column(name = "number") 
private String number; //immutable

@Column(name = "capacity")
private Integer capacity;

@ManyToOne(fetch = FetchType.LAZY, optional = false)
@JoinColumn(name = "building_id")
private Building building; //immutable

Room() {
    // default constructor
}

public Room(Building building, String number) {
    // constructor with required field
    notNull(building, "Method called with null parameter (application)");
    notNull(number, "Method called with null parameter (name)");

    this.building = building;
    this.number = number;
}

public Integer getId(){
    return id;
}

public Building getBuilding() {
    return building;
}

public String getNumber() {
    return number;
}


public void setCapacity(Integer capacity) {
    this.capacity = capacity;
}

//no setters for number, building nor id
}

I don't see a point of comparing equality of entities based on business fields in every case of JPA Entities. That might be more of a case if these JPA entities are thought of as Domain-Driven ValueObjects, instead of Domain-Driven Entities (which these code examples are for).

Ids is the array of object ids:

const ids =  [
    '4ed3ede8844f0f351100000c',
    '4ed3f117a844e0471100000d', 
    '4ed3f18132f50c491100000e',
];

Using Mongoose with callback:

Model.find().where('_id').in(ids).exec((err, records) => {});

Using Mongoose with async function:

const records = await Model.find().where('_id').in(ids).exec();

Or more concise:

const records = await Model.find({ '_id': { $in: ids } });

Don't forget to change Model with your actual model.

I use WinForms and my way to use File.Exists(string path) is the next one:

public bool FileExists(string fileName)
{
    var workingDirectory = Environment.CurrentDirectory;
    var file = $"{workingDirectory}\{fileName}";
    return File.Exists(file);
}

fileName must include the extension like myfile.txt

Same question as @Dan - why not StringReader ?

If it has to be InputStreamReader, then:

String charset = ...; // your charset
byte[] bytes = string.getBytes(charset);
ByteArrayInputStream bais = new ByteArrayInputStream(bytes);
InputStreamReader isr = new InputStreamReader(bais);

If you don't like "verbosity" you can always wrap your code in a short method:

private void msgbox(String s){
   JOptionPane.showMessageDialog(null, s);
}

and the usage:

msgbox("don't touch that!");

You must use the Invoke-Command cmdlet to launch this external program. Normally it works without an effort.

If you need more than one command you should use the Invoke-Expression cmdlet with the -scriptblock option.

This was done using Toad for Oracle 12.8.0.49

ALTER TABLE SCHEMA.TABLENAME 
    MODIFY (COLUMNNAME NEWDATATYPE(LENGTH)) ;

For example,

ALTER TABLE PAYROLL.EMPLOYEES

It could be because of couple of Browser settings. Try with these options checked..

Tools > Internet Options > Advanced > Enable Integrated Windows Authentication (works with Integrated Windows Authentication set on IIS)

Tools > Internet Options> Security > Local Intranet > Custom Level > Automatic Logon

Worst case, try adding localhost to the Trusted sites.

If you are in a network, you can also try debugging by getting a network trace. Could be because of some proxy trying to authenticate.

I had the same problem. I Check the last line of PostgreSQL log files in /var/log/postgresql. There was an unrecognized configuration parameter in file /etc/postgresql/9.5/main/postgresql.conf. Commenting the error line in postgresql.conf resolved my problem.

You may use numpy.append()...

import numpy

B = numpy.array([3])
A = numpy.array([1, 2, 2])
B = numpy.append( B , A )

print B

> [3 1 2 2]

This will not create two separate arrays but will append two arrays into a single dimensional array.

For those who are getting to this question via google... this error can also happen if you try to rename a field that is acting as a foreign key.

Sigh. Back in the 70s I was the "system programmer" (sysadmin) for an IBM 370 system, and my employer was a member of the IBM users group SHARE. It would sometimes happen thatsomebody submitted an APAR (bug report) on some unexpected behavior of some CMS command, and IBM would respond NOTABUG: the command does what it was designed to do (and what the documentation says).

SHARE came up with a counter to this: BAD -- Broken As Designed. I think this might apply to this implementation of equals for arrays.

There's nothing wrong with the implementation of Object.equals. Object has no data members, so there is nothing to compare. Two "Object"s are equal if and only if they are, in fact, the same Object (internally, the same address and length).

But that logic doesn't apply to arrays. Arrays have data, and you expect comparison (via equals) to compare the data. Ideally, the way Arrays.deepEquals does, but at least the way Arrays.equals does (shallow comparison of the elements).

So the problem is that array (as a built-in object) does not override Object.equals. String (as a named class) does override Object.equals and give the result you expect.

Other answers given are correct: [...].equals([....]) simply compares the pointers and not the contents. Maybe someday somebody will correct this. Or maybe not: how many existing programs would break if [...].equals actually compared the elements? Not many, I suspect, but more than zero.

You get an extension ID when you upload your extension to Google Web Store. Ie. Adblock has URL https://chrome.google.com/webstore/detail/cfhdojbkjhnklbpkdaibdccddilifddb and the last part of this URL is its extension ID cfhdojbkjhnklbpkdaibdccddilifddb.

If you wish to read installed extension IDs from your extension, check out the managment module. chrome.management.getAll allows to fetch information about all installed extensions.

You can look at outline with offset but this needs some padding to exists on your div. Or you can absolutely position a border div inside, something like

<div id='parentDiv' style='position:relative'>
  <div id='parentDivsContent'></div>
  <div id='fakeBordersDiv' 
       style='position: absolute;width: 100%;
              height: 100%;
              z-index: 2;
              border: 2px solid;
              border-radius: 2px;'/>
</div>

You might need to fiddle with margins on the fake borders div to fit it as you like.

answer shouldn't be a pointer, the intent is obviously to hold a character. scanf takes the address of this character, so it should be called as

char answer;
scanf(" %c", &answer);

Next, your "or" statement is formed incorrectly.

if (answer == 'Y' || answer == 'y')

What you wrote originally asks to compare answer with the result of 'Y' || 'y', which I'm guessing isn't quite what you wanted to do.

Just do:

Stream.of(stream1, stream2, Stream.of(element)).flatMap(identity());

where identity() is a static import of Function.identity().

Concatenating multiple streams into one stream is the same as flattening a stream.

However, unfortunately, for some reason there is no flatten() method on Stream, so you have to use flatMap() with the identity function.

specifically I want to overload Boolean.Parse to allow an int argument.

Would an extension for int work?

public static bool ToBoolean(this int source){
    // do it
    // return it
}

Then you can call it like this:

int x = 1;

bool y = x.ToBoolean();

Why is the default 8-bit codepage called "ANSI"?

From Unicode and Windows XP
by Cathy Wissink
Program Manager, Windows Globalization
Microsoft Corporation
May 2002

Despite the underlying Unicode support on Windows NT 3.1, code page support continued to be necessary for many of the higher-level applications and components included in the system, explaining the pervasive use of the “A” [ANSI] versions of the Win32 APIs rather than the “W” [“wide” or Unicode] versions. (The term “ANSI” as used to signify Windows code pages is a historical reference, but is nowadays a misnomer that continues to persist in the Windows community. The source of this comes from the fact that the Windows code page 1252 was originally based on an ANSI draft, which became ISO Standard 8859-1. However, in adding code points to the range reserved for control codes in the ISO standard, the Windows code page 1252 and subsequent Windows code pages originally based on the ISO 8859-x series deviated from ISO. To this day, it is not uncommon to have the development community, both within and outside of Microsoft, confuse the 8859-1 code page with Windows 1252, as well as see “ANSI” or “A” used to signify Windows code page support.)

I had a similar problem and it was caused by the placement of the Timer initialisation.

It was placed in a method that was invoked oftener.

Try this:

Timer waitTimer;

  void exampleMethod() {

   if (waitTimer == null ) {
    //initialize your Timer here
    ...
   }

The "cancel()" method only canceled the latest Timer. The older ones were ignored an didn't stop running.

I had this problem minutes ago. It went away when I added 'extern "C"' to the main() definition.

Oddly, another simple program I wrote yesterday is almost identical, does not have the extern "C", yet compiled without this linker error.

This makes me think the problem is some subtle setting to be found deep in some configuration dialog, and that 'extern "C"' doesn't really solve the underlying problem, but superficially makes things work.

I had a similar issue and it turned out that i had to add an extra entry in cmake to include the files.

Since i was also using the zmq library I had to add this to the included libraries as well.

Download the .whl file from this link.

The name of the file is: wxPython-3.0.2.0-cp27-none-win32.whl for Windows 32 bit and python 2.7 and wxPython-3.0.2.0-cp27-none-win_amd64.whl for Windows 64 bit and python 2.7.

Then in the command prompt: pip install location-of-the-above-saved-file

You can directly return a different view like:

return View("NameOfView", Model);

Or you can make a partial view and can return like:

return PartialView("PartialViewName", Model);

esp is as you say it is, the top of the stack.

ebp is usually set to esp at the start of the function. Function parameters and local variables are accessed by adding and subtracting, respectively, a constant offset from ebp. All x86 calling conventions define ebp as being preserved across function calls. ebp itself actually points to the previous frame's base pointer, which enables stack walking in a debugger and viewing other frames local variables to work.

Most function prologs look something like:

push ebp      ; Preserve current frame pointer
mov ebp, esp  ; Create new frame pointer pointing to current stack top
sub esp, 20   ; allocate 20 bytes worth of locals on stack.

Then later in the function you may have code like (presuming both local variables are 4 bytes)

mov [ebp-4], eax    ; Store eax in first local
mov ebx, [ebp - 8]  ; Load ebx from second local

FPO or frame pointer omission optimization which you can enable will actually eliminate this and use ebp as another register and access locals directly off of esp, but this makes debugging a bit more difficult since the debugger can no longer directly access the stack frames of earlier function calls.

EDIT:

For your updated question, the missing two entries in the stack are:

var_C = dword ptr -0Ch
var_8 = dword ptr -8
var_4 = dword ptr -4
*savedFramePointer = dword ptr 0*
*return address = dword ptr 4*
hInstance = dword ptr  8h
PrevInstance = dword ptr  0C
hlpCmdLine = dword ptr  10h
nShowCmd = dword ptr  14h

This is because the flow of the function call is:

• Push parameters (hInstance, etc.)
• Call function, which pushes return address
• Push ebp
• Allocate space for locals

and to get it :

public void onItemClick(AdapterView<?> parent, View view,
                int position, long id) {

                Log.d(getLocalClassName(), "onItemClick(" + view + ","
                        + position + "," + id + ")");
        }
    });

Schema is a container of objects. It is owned by a user.

Another option to consider is disabling it when you do not want it to be able to be changed and enabling it:

//When select should be disabled:
{
    $('#my_select').attr('disabled', 'disabled');
}

//When select should not be disabled
{
    $('#my_select').removeAttr('disabled');
}

Update since your comment (if I understand the functionality you want):

$("#dropdown").change(function()
{
    var answer = confirm("Are you sure you want to change your selection?")
    {
        if(answer)
        {
            //Update dropdown (Perform update logic)
        }
        else
        {
            //Allow Change (Do nothing - allow change)
        } 
    }            
}); 

Demo

The different methods are indications of priority. As you've listed them, they're going from least to most important. I think how you specifically map them to debug logs in your code depends on the component or app you're working on, as well as how Android treats them on different build flavors (eng, userdebug, and user). I have done a fair amount of work in the native daemons in Android, and this is how I do it. It may not apply directly to your app, but there may be some common ground. If my explanation sounds vague, it's because some of this is more of an art than a science. My basic rule is to be as efficient as possible, ensure you can reasonably debug your component without killing the performance of the system, and always check for errors and log them.

V - Printouts of state at different intervals, or upon any events occurring which my component processes. Also possibly very detailed printouts of the payloads of messages/events that my component receives or sends.

D - Details of minor events that occur within my component, as well as payloads of messages/events that my component receives or sends.

I - The header of any messages/events that my component receives or sends, as well as any important pieces of the payload which are critical to my component's operation.

W - Anything that happens that is unusual or suspicious, but not necessarily an error.

E - Errors, meaning things that aren't supposed to happen when things are working as they should.

The biggest mistake I see people make is that they overuse things like V, D, and I, but never use W or E. If an error is, by definition, not supposed to happen, or should only happen very rarely, then it's extremely cheap for you to log a message when it occurs. On the other hand, if every time somebody presses a key you do a Log.i(), you're abusing the shared logging resource. Of course, use common sense and be careful with error logs for things outside of your control (like network errors), or those contained in tight loops.

Maybe Bad

Log.i("I am here");

Good

Log.e("I shouldn't be here");

With all this in mind, the closer your code gets to "production ready", the more you can restrict the base logging level for your code (you need V in alpha, D in beta, I in production, or possibly even W in production). You should run through some simple use cases and view the logs to ensure that you can still mostly understand what's happening as you apply more restrictive filtering. If you run with the filter below, you should still be able to tell what your app is doing, but maybe not get all the details.

logcat -v threadtime MyApp:I *:S

You could always create an intermediate class/interface that would satisfy the generic type that you are wanting to specify. For example, if Foo was an interface, you could create the following interface in your test class.

private interface FooBar extends Foo<Bar>
{
}

In situations where Foo is a non-final class, you could just extend the class with the following code and do the same thing:

public class FooBar extends Foo<Bar>
{
}

Then you could consume either of the above examples with the following code:

Foo<Bar> mockFoo = mock(FooBar.class);
when(mockFoo.getValue()).thenReturn(new Bar());

Do you want to know if a type is the same type as int64_t or do you want to know if something is 64 bits? Based on your proposed solution, I think you're asking about the latter. In that case, I would do something like

template<typename T>
bool is_64bits() { return sizeof(T) * CHAR_BIT == 64; } // or >= 64

for my case Footer method was having malformed html code (missing td) causing error on osx.

public function Footer() {
$this->SetY(-40);
$html = <<<EOD

EOD;
$this->writeHTML($html);
}

this.$router.go(this.$router.currentRoute)

Vue-Router Docs:

I checked vue-router repo on GitHub and it seems that there isn't reload() method any more. But in the same file, there is: currentRoute object.

Source: vue-router/src/index.js
Docs: docs

get currentRoute (): ?Route {
    return this.history && this.history.current
  }

Now you can use this.$router.go(this.$router.currentRoute) for reload current route.

Simple example.

Version for this answer:

"vue": "^2.1.0",
"vue-router": "^2.1.1"

If you're having this sort of problem with a while loop, rather than a for loop, for example:

var i = 0;
while (i < 5) {
  setTimeout(function() {
    console.log(i);
  }, i * 1000);
  i++;
}

The technique to close over the current value is a bit different. Declare a block-scoped variable with const inside the while block, and assign the current i to it. Then, wherever the variable is being used asynchronously, replace i with the new block-scoped variable:

var i = 0;
while (i < 5) {
  const thisIterationI = i;
  setTimeout(function() {
    console.log(thisIterationI);
  }, i * 1000);
  i++;
}

For older browsers that don't support block-scoped variables, you can use an IIFE called with i:

var i = 0;
while (i < 5) {
  (function(innerI) {
    setTimeout(function() {
      console.log(innerI);
    }, innerI * 1000);
  })(i);
  i++;
}

If the asynchronous action to be invoked happens to be setTimeout like the above, you can also call setTimeout with a third parameter to indicate the argument to call the passed function with:

var i = 0;
while (i < 5) {
  setTimeout(
    (thisIterationI) => { // Callback
      console.log(thisIterationI);
    },
    i * 1000, // Delay
    i // Gets passed to the callback; becomes thisIterationI
  );
  i++;
}

So, strictly speaking, the "type of a variable" is always present, and can be passed around as a type parameter. For example:

val x = 5
def f[T](v: T) = v
f(x) // T is Int, the type of x

But depending on what you want to do, that won't help you. For instance, may want not to know what is the type of the variable, but to know if the type of the value is some specific type, such as this:

val x: Any = 5
def f[T](v: T) = v match {
  case _: Int    => "Int"
  case _: String => "String"
  case _         => "Unknown"
}
f(x)

Here it doesn't matter what is the type of the variable, Any. What matters, what is checked is the type of 5, the value. In fact, T is useless -- you might as well have written it def f(v: Any) instead. Also, this uses either ClassTag or a value's Class, which are explained below, and cannot check the type parameters of a type: you can check whether something is a List[_] (List of something), but not whether it is, for example, a List[Int] or List[String].

Another possibility is that you want to reify the type of the variable. That is, you want to convert the type into a value, so you can store it, pass it around, etc. This involves reflection, and you'll be using either ClassTag or a TypeTag. For example:

val x: Any = 5
import scala.reflect.ClassTag
def f[T](v: T)(implicit ev: ClassTag[T]) = ev.toString
f(x) // returns the string "Any"

A ClassTag will also let you use type parameters you received on match. This won't work:

def f[A, B](a: A, b: B) = a match {
  case _: B => "A is a B"
  case _ => "A is not a B"
}

But this will:

val x = 'c'
val y = 5
val z: Any = 5
import scala.reflect.ClassTag
def f[A, B: ClassTag](a: A, b: B) = a match {
  case _: B => "A is a B"
  case _ => "A is not a B"
}
f(x, y) // A (Char) is not a B (Int)
f(x, z) // A (Char) is a B (Any)

Here I'm using the context bounds syntax, B : ClassTag, which works just like the implicit parameter in the previous ClassTag example, but uses an anonymous variable.

One can also get a ClassTag from a value's Class, like this:

val x: Any = 5
val y = 5
import scala.reflect.ClassTag
def f(a: Any, b: Any) = {
  val B = ClassTag(b.getClass)
  ClassTag(a.getClass) match {
    case B => "a is the same class as b"
    case _ => "a is not the same class as b"
  }
}
f(x, y) == f(y, x) // true, a is the same class as b

A ClassTag is limited in that it only covers the base class, but not its type parameters. That is, the ClassTag for List[Int] and List[String] is the same, List. If you need type parameters, then you must use a TypeTag instead. A TypeTag however, cannot be obtained from a value, nor can it be used on a pattern match, due to JVM's erasure.

Examples with TypeTag can get quite complex -- not even comparing two type tags is not exactly simple, as can be seen below:

import scala.reflect.runtime.universe.TypeTag
def f[A, B](a: A, b: B)(implicit evA: TypeTag[A], evB: TypeTag[B]) = evA == evB
type X = Int
val x: X = 5
val y = 5
f(x, y) // false, X is not the same type as Int

Of course, there are ways to make that comparison return true, but it would require a few book chapters to really cover TypeTag, so I'll stop here.

Finally, maybe you don't care about the type of the variable at all. Maybe you just want to know what is the class of a value, in which case the answer is rather simple:

val x = 5
x.getClass // int -- technically, an Int cannot be a class, but Scala fakes it

It would be better, however, to be more specific about what you want to accomplish, so that the answer can be more to the point.

(Sorry I can't comment just yet, otherwise I would)

To add to Christian's answer you might consider using json_encode and json_decode instead of serialize and unserialize to keep you safe. See a warning from the PHP man page:

Warning

Do not pass untrusted user input to unserialize(). Unserialization can result in code being loaded and executed due to object instantiation and autoloading, and a malicious user may be able to exploit this. Use a safe, standard data interchange format such as JSON (via json_decode() and json_encode()) if you need to pass serialized data to the user.

So your final solution might have the following:

$file = '/tmp/file';
$content = json_encode($my_variable);
file_put_contents($file, $content);
$content = json_decode(file_get_contents($file), TRUE);

we use Gson.

Gson gson = new Gson();
Type gsonType = new TypeToken<HashMap>(){}.getType();
String gsonString = gson.toJson(elements,gsonType);

iptalbes tool relies on a kernel module interacting with netfilter to control network traffic.

This error happens while iptalbes cannot found that module in kernel, so iptables suggest you to upgrade it :)

Perhaps iptables or your kernel needs to be upgraded.

However in most cases it's just the module not added to kernel or being banned, try this command to check whether be banned:

cd /etc/modprobe.d/ && grep -nr iptable_nat

if the command shows any rule matched, such as blacklist iptable_nat or install iptable_nat /bin/true, delete it. Since iptalbes will cost some performance, it's not strange to ban it while not necessary.

If nothing found in blacklist, try add iptable-nat to the kernal manual:

modprobe iptable-nat

If all of above not works, you can consider really upgrade your kernal...

Use only one server side form tag.

Check your Master page for <form runat="server"> - there should be only one.

Why do you need more than one?

Using pieces from all of these answers and the comments, I put this together for anyone who sees this question in the future. It covers all of the situations listed in the other answers

    # If using ISE
    if ($psISE) {
        $ScriptPath = Split-Path -Parent $psISE.CurrentFile.FullPath
    # If Using PowerShell 3 or greater
    } elseif($PSVersionTable.PSVersion.Major -gt 3) {
        $ScriptPath = $PSScriptRoot
    # If using PowerShell 2 or lower
    } else {
        $ScriptPath = split-path -parent $MyInvocation.MyCommand.Path

Proxies can make this a little tricky, make sure to check out ProxyFix (Flask docs) if you are using one. Take a look at request.environ in your particular environment. With nginx I will sometimes do something like this:

from flask import request   
request.environ.get('HTTP_X_REAL_IP', request.remote_addr)   

When proxies, such as nginx, forward addresses, they typically include the original IP somewhere in the request headers.

Update See the flask-security implementation. Again, review the documentation about ProxyFix before implementing. Your solution may vary based on your particular environment.

Just to include one more alternative, you could also use this:

find "/starting/path" -type f -regextype posix-extended -regex "^.*\.(php|html|js)$" -exec grep -EH '(document\.cookie|setcookie)' {} \;

Where:

• -regextype posix-extended tells find what kind of regex to expect
• -regex "^.*\.(php|html|js)$" tells find the regex itself filenames must match

• -exec grep -EH '(document\.cookie|setcookie)' {} \; tells find to run the command (with its options and arguments) specified between the -exec option and the \; for each file it finds, where {} represents where the file path goes in this command.

  while

  • E option tells grep to use extended regex (to support the parentheses) and...
  • H option tells grep to print file paths before the matches.

And, given this, if you only want file paths, you may use:

find "/starting/path" -type f -regextype posix-extended -regex "^.*\.(php|html|js)$" -exec grep -EH '(document\.cookie|setcookie)' {} \; | sed -r 's/(^.*):.*$/\1/' | sort -u

Where

• | [pipe] send the output of find to the next command after this (which is sed, then sort)
• r option tells sed to use extended regex.
• s/HI/BYE/ tells sed to replace every First occurrence (per line) of "HI" with "BYE" and...
• s/(^.*):.*$/\1/ tells it to replace the regex (^.*):.*$ (meaning a group [stuff enclosed by ()] including everything [.* = one or more of any-character] from the beginning of the line [^] till' the first ':' followed by anything till' the end of line [$]) by the first group [\1] of the replaced regex.
• u tells sort to remove duplicate entries (take sort -u as optional).

...FAR from being the most elegant way. As I said, my intention is to increase the range of possibilities (and also to give more complete explanations on some tools you could use).

• The code 302 indicates a temporary redirection.
• One of the most notable features that differentiate it from a 301 redirect is that, in the case of 302 redirects, the strength of the SEO is not transferred to a new URL.
• This is because this redirection has been designed to be used when there is a need to redirect content to a page that will not be the definitive one. Thus, once the redirection is eliminated, the original page will not have lost its positioning in the Google search engine.

EXAMPLE:- Although it is not very common that we find ourselves in need of a 302 redirect, this option can be very useful in some cases. These are the most frequent cases:

• When we realize that there is some inappropriate content on a page. While we solve the problem, we can redirect the user to another page that may be of interest.
• In the event that an attack on our website requires the restoration of any of the pages, this redirect can help us minimize the incidence.

A redirect 302 is a code that tells visitors of a specific URL that the page has been moved temporarily, directing them directly to the new location.

• In other words, redirect 302 is activated when Google robots or other search engines request to load a specific page. At that moment, thanks to this redirection, the server returns an automatic response indicating a new URL.

• In this way errors and annoyances are avoided both to search engines and users, guaranteeing smooth navigation.

In Snow Leopard and later Mac OS versions, it isn't enough to codesign the gdb executable.

You have to follow this guide to make it work: http://www.opensource.apple.com/source/lldb/lldb-69/docs/code-signing.txt

The guide explains how to do it for lldb, but the process is exactly the same for gdb.

I also had to register the closing function inside the form's "InitializeComponent()" method:

private void InitializeComponent() {
// ...
this.FormClosing += FrmMain_FormClosing;
// ...
}

My "FormClosing" function looks similar to the given answer (https://stackoverflow.com/a/2683846/3323790):

private void FrmMain_FormClosing(object sender, FormClosingEventArgs e) {
    if (e.CloseReason == CloseReason.UserClosing){
        MessageBox.Show("Closed by User", "UserClosing");
    }

    if (e.CloseReason == CloseReason.WindowsShutDown){
        MessageBox.Show("Closed by Windows shutdown", "WindowsShutDown");
    }
}

One more thing to mention: There is also a "FormClosed" function which occurs after "FormClosing". To use this function, register it as shown below:

this.FormClosed += MainPage_FormClosed;

private void MainPage_FormClosing(object sender, FormClosingEventArgs e)
{
// your code after the form is closed
}

IE displays a active x warning and ask for permission if you allow it to run or not. To overcome this the only solution is to;

1. Open Internet Explorer.
2. Click the Tools menu, and then click Internet Options.
3. On the Security tab, click the Custom level button.
4. Scroll down the Security Settings list until you see ActiveX controls and plug-ins.
5. For Automatic prompting for ActiveX controls, click Enable.
6. Scroll down to Download signed ActiveX controls and click Enable or Prompt.
7. Scroll down to Run ActiveX controls and plug-ins and click Enable or Prompt.
8. Scroll down to Script ActiveX controls marked safe for scripting and click Enable or Prompt.
9. Click OK, and then click OK again.

There is no way to overcome this issue except changing manually Internet explorer settings. Try checking if plugin works fine while changed settings. If its still not working or not showing any warning is display try checking console for other errors which are not related to active x. Good luck!

If you define function type first then it would be looked like

type Callback = (n: number) => void;

class Foo {
    save(callback: Callback) : void {        
        callback(42);
    }
}

var foo = new Foo();
var stringCallback = (result: string) : void => {
    console.log(result);
}

var numberCallback = (result: number) : void => {
    console.log(result);
}

foo.save(stringCallback); //--will be showing error
foo.save(numberCallback);

Without function type by using plain property syntax it would be:

class Foo {
    save(callback: (n: number) => void) : void {        
        callback(42);
    }
}

var foo = new Foo();
var stringCallback = (result: string) : void => {
    console.log(result);
}

var numberCallback = (result: number) : void => {
    console.log(result);
}

foo.save(stringCallback); //--will be showing error
foo.save(numberCallback);

If you want by using an interface function like c# generic delegates it would be:

interface CallBackFunc<T, U>
{
    (input:T): U;
};

class Foo {
    save(callback: CallBackFunc<number,void>) : void {        
        callback(42);
    }
}

var foo = new Foo();
var stringCallback = (result: string) : void => {
    console.log(result);
}

var numberCallback = (result: number) : void => {
    console.log(result);
}

let strCBObj:CallBackFunc<string,void> = stringCallback;
let numberCBObj:CallBackFunc<number,void> = numberCallback;

foo.save(strCBObj); //--will be showing error
foo.save(numberCBObj);

This code is well-formed. You only have to pay attention that the definition of the template is visible at the point of instantiation. To quote the standard, § 14.7.2.4:

The definition of a non-exported function template, a non-exported member function template, or a non-exported member function or static data member of a class template shall be present in every translation unit in which it is explicitly instantiated.

I have changed in my activity but effected. Here is my code:

View layout = getLayoutInflater().inflate(R.layout.list_group,null);
        try {
            LinearLayout linearLayout = (LinearLayout) layout.findViewById(R.id.ldrawernav);
            linearLayout.setBackgroundColor(Color.parseColor("#ffffff"));
        }
        catch (Exception e) {

        }

    }

If you're not using the id for anything other than code-behind reference (since .net mangles the ids), you could use a panel control and reference it in your codebehind:

<asp:panel runat="server" id="classMe"></asp:panel>

classMe.cssClass = "someClass"

I realised that I hadn't run/built my framework with the Generic Device, which strangely lead to these issues. I just put the framework back in and it worked.

Aren't you missing the #include "B.h" in A.h?

The Classloader API doesn't have an "enumerate" method, because class loading is an "on-demand" activity -- you usually have thousands of classes in your classpath, only a fraction of which will ever be needed (the rt.jar alone is 48MB nowadays!).

So, even if you could enumerate all classes, this would be very time- and memory-consuming.

The simple approach is to list the concerned classes in a setup file (xml or whatever suits your fancy); if you want to do this automatically, restrict yourself to one JAR or one class directory.

If you want to apply an extra small class in Bootstrap 4,you need to use col-. important thing to know is that col-xs- is dropped in Bootstrap4

You aren't building your formula right.

Worksheets("EmployeeCosts").Range("B" & var1a).Formula =  "=SUM(H5:H" & var1a & ")"

This does the same as the following lines do:

Dim myFormula As String
myFormula = "=SUM(H5:H"
myFormula = myFormula & var1a
myformula = myformula & ")"

which is what you are trying to do.

Also, you want to have the = at the beginning of the formala.

I think a much better method is to do this in the Program.cs file where you usually have Application.Run(form1), in this way you get a cleaner approach, Login form does not need to be coupled to Main form, you simply show the login and if it returns true you display the main form otherwise the error.

If you want to do this via the designer you can do it by following the instructions here "Save changes is not permitted" when changing an existing column to be nullable

Javascript

  // on toggle method
  // to check status of checkbox
  function onToggle() {
    // check if checkbox is checked
    if (document.querySelector('#my-checkbox').checked) {
      // if checked
      console.log('checked');
    } else {
      // if unchecked
      console.log('unchecked');
    }
  }

HTML

<input id="my-checkbox" type="checkbox" onclick="onToggle()">

Regarding the first (and great) answer from chris who proposed a solution to the situation where the class members are held as a "true composite" members (i.e.- not as pointers nor references):

The note is a bit large, so I will demonstrate it here with some sample code.

When you chose to hold the members as I mentioned, you have to keep in mind also these two things:

1. For every "composed object" that does not have a default constructor - you must initialize it in the initialization list of all the constructor's of the "father" class (i.e.- BigMommaClass or MyClass in the original examples and MyClass in the code below), in case there are several (see InnerClass1 in the example below). Meaning, you can "comment out" the m_innerClass1(a) and m_innerClass1(15) only if you enable the InnerClass1 default constructor.

2. For every "composed object" that does have a default constructor - you may initialize it within the initialization list, but it will work also if you chose not to (see InnerClass2 in the example below).

See sample code (compiled under Ubuntu 18.04 (Bionic Beaver) with g++ version 7.3.0):

#include <iostream>

using namespace std;

class InnerClass1
{
    public:
        InnerClass1(int a) : m_a(a)
        {
            cout << "InnerClass1::InnerClass1 - set m_a:" << m_a << endl;
        }

        /* No default constructor
        InnerClass1() : m_a(15)
        {
            cout << "InnerClass1::InnerClass1() - set m_a:" << m_a << endl;
        }
        */

        ~InnerClass1()
        {
            cout << "InnerClass1::~InnerClass1" << endl;
        }

    private:
        int m_a;
};

class InnerClass2
{
    public:
        InnerClass2(int a) : m_a(a)
        {
            cout << "InnerClass2::InnerClass2 - set m_a:" << m_a << endl;
        }

        InnerClass2() : m_a(15)
        {
            cout << "InnerClass2::InnerClass2() - set m_a:" << m_a << endl;
        }

        ~InnerClass2()
        {
            cout << "InnerClass2::~InnerClass2" << endl;
        }

    private:
        int m_a;
};

class MyClass
{
    public:
        MyClass(int a, int b) : m_innerClass1(a), /* m_innerClass2(a),*/ m_b(b)
        {
            cout << "MyClass::MyClass(int b) - set m_b to:" << m_b << endl;
        }

         MyClass() : m_innerClass1(15), /*m_innerClass2(15),*/ m_b(17)
        {
            cout << "MyClass::MyClass() - m_b:" << m_b << endl;
        }

        ~MyClass()
        {
            cout << "MyClass::~MyClass" << endl;
        }

    private:
        InnerClass1 m_innerClass1;
        InnerClass2 m_innerClass2;
        int m_b;
};

int main(int argc, char** argv)
{
    cout << "main - start" << endl;

    MyClass obj;

    cout << "main - end" << endl;
    return 0;
}

You need to convert Array to string :

//arrayOfValues = [1, 2, 3];  
$.get('/controller/MyAction', { arrayOfValues: "1, 2, 3" }, function (data) {...

this works even in form of int, long or string

public ActionResult MyAction(int[] arrayOfValues )

You can use below command if you want to print entire line and file name if the occurrence of particular word in current directory you are searching.

grep -m 1 -r "Not caching" * | head -1

Try the Following Code:

using System.Text.RegularExpressions;
if  (!Regex.IsMatch(txtEmail.Text, @"^[a-z,A-Z]{1,10}((-|.)\w+)*@\w+.\w{3}$"))
        MessageBox.Show("Not valid email.");

Here is some text from MSDN about unmanaged code.

Some library code needs to call into unmanaged code (for example, native code APIs, such as Win32). Because this means going outside the security perimeter for managed code, due caution is required.

Here is some other complimentary explication about Managed code:

• Code that is executed by the CLR.
• Code that targets the common language runtime, the foundation of the .NET Framework, is known as managed code.
• Managed code supplies the metadata necessary for the CLR to provide services such as memory management, cross-language integration, code access security, and automatic lifetime control of objects. All code based on IL executes as managed code.
• Code that executes under the CLI execution environment.

For your problem:

I think it's because NUnit execute your code for UnitTesting and might have some part of it that is unmanaged. But I am not sure about it, so do not take this for gold. I am sure someone will be able to give you more information about it. Hope it helps!

You could add a Category partial and a Product partial, each would take a smaller part of the main model as it's own model, i.e. Category's model type might be an IEnumerable, you would pass in Model.Theme to it. The Product's partial might be an IEnumerable that you pass Model.Products into (from within the Category partial).

I'm not sure if that would be the right way forward, but would be interested in knowing.

EDIT

Since posting this answer, I've used EditorTemplates and find this the easiest way to handle repeating input groups or items. It handles all your validation message problems and form submission/model binding woes automatically.

IMO, froadie's simple concatenation is fine for a simple case like you presented. If you want to put together several strings, the string join method seems to be preferred:

the_text = ''.join(['the ', 'quick ', 'brown ', 'fox ', 'jumped ', 'over ', 'the ', 'lazy ', 'dog.'])

Edit: Note that join wants an iterable (e.g. a list) as its single argument.

Using regedit, remove the entries corresponding to java 7. It will work.

You can easily make SSH connections using SSHLibrary. Read this post :

You would use the read.csv function; for example:

dat = read.csv("spam.csv", header = TRUE)

You can also reference this tutorial for more details.

Note: make sure the .csv file to read is in your working directory (using getwd()) or specify the right path to file. If you want, you can set the current directory using setwd.

in this case, I use space for APP_NAME key in .env file.

and have below error :

Don't use space in APP_NAME key !!

Unless you have a mail server set up on your local computer, setting SMTP = localhost won't have any effect.

In days gone by (long ago), it was sufficient to set the value of SMTP to the address of your ISP's SMTP server. This now rarely works because most ISPs insist on authentication with a username and password. However, the PHP mail() function doesn't support SMTP authentication. It's designed to work directly with the mail transport agent of the local server.

You either need to set up a local mail server or to use a PHP classs that supports SMTP authentication, such as Zend_Mail or PHPMailer. The simplest solution, however, is to upload your mail processing script to your remote server.

You can do this.

You should be using DATEADD is Sql server so if try this simple select you will see the affect

Select DATEADD(Month, -1, getdate())

Result

2013-04-20 14:08:07.177

in your case try this query

SELECT name
FROM (
SELECT name FROM 
Hist_answer
WHERE id_city='34324' AND datetime >= DATEADD(month,-1,GETDATE())
UNION ALL
SELECT name FROM 
Hist_internet
WHERE id_city='34324' AND datetime >= DATEADD(month,-1,GETDATE())
) x
GROUP BY name ORDER BY name

Make sure you are in the root drive. You will see something like this.

Make sure you are using Javascript module or not?! if using js6 modules your html events attributes won't work. in that case you must bring your function from global scope to module scope. Just add this to your javascript file: window.functionName= functionName;

example:

<h1 onClick="functionName">some thing</h1>

Simply put, if an exception or error is thrown, something's wrong. It may not be something very wrong, but creating, throwing, and catching errors and exceptions just for the sake of using goto statements is not a good idea, and it's rarely done. 99% of the time, there was a problem somewhere.

Problems need to be dealt with. Just like how it is in life, in programming, if you just leave problems alone and try to ignore them, they don't just go away on their own a lot of times; instead they get bigger and multiply. To prevent a problem from growing on you and striking again further down the road, you either 1) eliminate it and clean up the mess afterwards, or 2) contain it and clean up the mess afterwards.

Just ignoring exceptions and errors and leaving them be like that is a good way to experience memory leaks, outstanding database connections, needless locks on file permissions, etc.

On rare occasions, the problem is so miniscule, trivial, and - aside from needing a try...catch block - self-contained, that there really is just no mess to be cleaned up afterwards. These are the only occasions when this best practice doesn't necessarily apply. In my experience, this has generally meant that whatever the code is doing is basically petty and forgoable, and something like retry attempts or special messages are worth neither the complexity nor holding the thread up on.

At my company, the rule is to almost always do something in a catch block, and if you don't do anything, then you must always place a comment with a very good reason why not. You must never pass or leave an empty catch block when there is anything to be done.

No - if you want to convert ALL elements of a list, you'll have to touch ALL elements of that list one way or another.

You can specify / write the iteration in different ways (foreach()......, or .ConvertAll() or whatever), but in the end, one way or another, some code is going to iterate over each and every element and convert it.

I find this the best and cleanest solution to it. Using text-indent on the input element

CSS:

#icon{
    background-image:url(../images/icons/dollar.png); 
    background-repeat: no-repeat; 
    background-position: 2px 3px;
}

HTML:

<input id="icon" style="text-indent:17px;" type="text" placeholder="Username" />

You can do this with jQuery :

$(document).ready(function(){_x000D_
  _x000D_
  $('.claimedRight').each(function (f) {_x000D_
_x000D_
      var newstr = $(this).text().substring(0,20);_x000D_
      $(this).text(newstr);_x000D_
_x000D_
    });_x000D_
})

<html>_x000D_

    <title></title>_x000D_
    <script         src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_

<body>_x000D_
    <span class="claimedRight" maxlength="20">Hello this is the first test string. _x000D_

    <span class="claimedRight" maxlength="20">Hello this is the second test string. _x000D_

C# introduces properties which do most of the heavy lifting for you...

ie

public string Name { get; set; }

is a C# shortcut to writing...

private string _name;

public string getName { return _name; }
public void setName(string value) { _name = value; }

Basically getters and setters are just means of helping encapsulation. When you make a class you have several class variables that perhaps you want to expose to other classes to allow them to get a glimpse of some of the data you store. While just making the variables public to begin with may seem like an acceptable alternative, in the long run you will regret letting other classes manipulate your classes member variables directly. If you force them to do it through a setter, you can add logic to ensure no strange values ever occur, and you can always change that logic in the future without effecting things already manipulating this class.

ie

private string _name;

public string getName { return _name; }
public void setName(string value) 
{ 
    //Don't want things setting my Name to null
    if (value == null) 
    {
        throw new InvalidInputException(); 
    }
    _name = value; 
}

you can also use the below code.

function activateController(){
     console.log('HELLO WORLD');
}

$scope.$on('$viewContentLoaded', function ($evt, data) {
    activateController();
});

You need to define a valid type of SelectParameter. This MSDN article describes the various types and how to use them.

The worse thing is not having a decent stack trace which you simply cannot generate using an HttpInterceptor (hope to stand corrected). All you get is a load of zone and rxjs useless bloat, and not the line or class that generated the error.

To do this you will need to generate a stack in an extended HttpClient, so its not advisable to do this in a production environment.

/**
 * Extended HttpClient that generates a stack trace on error when not in a production build.
 */
@Injectable()
export class TraceHttpClient extends HttpClient {
  constructor(handler: HttpHandler) {
    super(handler);
  }

  request(...args: [any]): Observable<any> {
    const stack = environment.production ? null : Error().stack;
    return super.request(...args).pipe(
      catchError((err) => {
        // tslint:disable-next-line:no-console
        if (stack) console.error('HTTP Client error stack\n', stack);
        return throwError(err);
      })
    );
  }
}

This is even easier than that with Visual Studio 2017. Follow these instructions: https://docs.microsoft.com/en-us/visualstudio/install/modify-visual-studio to modify using Microsoft Visual Studio Installer.

Once inside the Microsoft Visual Studio Installer, click modify under your installed Visual Studio package, make sure the Desktop development with C++ is checked, and the MFC and ATl support (x86 and x64), under summary.

I am not sure in Razor but in ASPX you do:

 <%if (item.Modify_Date != null)
  {%>
     <%=Html.Encode(String.Format("{0:D}", item.Modify_Date))%>     
<%} %>

There must be something similar in Razor. Hopefully this will help someone.

Use that code.that will help to solve your problem

@media print 
{
  @page { margin: 0; }
  body  { margin: 1.6cm; }
}

I was having this exact issue and this was because I was returning images from a server into component that is 1 step down the path. This what I mean. See file arrangement

*projectfolder/phpfiles/component.php*

Now my images folder was located here projectfolder/images/

Now I fixed it by adding ../ so that it could skip 1 step backwards

Goodluck

Some people show using LIKE or ILIKE, but those allow regex searches. Also you don't need to downcase in Ruby. You can let the database do it for you. I think it may be faster. Also first_or_create can be used after where.

# app/models/product.rb
class Product < ActiveRecord::Base

  # case insensitive name
  def self.ci_name(text)
    where("lower(name) = lower(?)", text)
  end
end

# first_or_create can be used after a where clause
Product.ci_name("Blue Jeans").first_or_create
# Product Load (1.2ms)  SELECT  "products".* FROM "products"  WHERE (lower(name) = lower('Blue Jeans'))  ORDER BY "products"."id" ASC LIMIT 1
# => #<Product id: 1, name: "Blue jeans", created_at: "2016-03-27 01:41:45", updated_at: "2016-03-27 01:41:45"> 

random_name = lambda length: ''.join(random.sample(string.letters, length))

length must be <= len(string.letters) = 53. result example

   >>> [random_name(x) for x in range(1,20)]
['V', 'Rq', 'YtL', 'AmUF', 'loFdS', 'eNpRFy', 'iWFGtDz', 'ZTNgCvLA', 'fjUDXJvMP', 'EBrPcYKUvZ', 'GmxPKCnbfih', 'nSiNmCRktdWZ', 'VWKSsGwlBeXUr', 'i

On Linux, see constant INET6_ADDRSTRLEN (include <arpa/inet.h>, see man inet_ntop). On my system (header "in.h"):

#define INET6_ADDRSTRLEN 46

The last character is for terminating NULL, as I belive, so the max length is 45, as other answers.

$(document).ready(function() {
    $("#form1").validate({
        rules: {
            field1: "required"
        },
        messages: {
            field1: "Please specify your name"
        }
    })
});

<form id="form1" name="form1">
     Field 1: <input id="field1" type="text" class="required">
    <input id="btn" type="submit" value="Validate">
</form>

You are also you using type="button". And I'm not sure why you ought to separate the submit button, place it within the form. It's more proper to do it that way. This should work.

Check the Windows Server 2003 Resource Kit Tools. There is a utility called Creatfil.

 CREATFIL.EXE
 -? : This message
 -FileName -- name of the new file
 -FileSize -- size of file in KBytes, default is 1024 KBytes

It is the similar to mkfile on Solaris.

Set is just an interface. In order to retain order, you have to use a specific implementation of that interface and the sub-interface SortedSet, for example TreeSet or LinkedHashSet. You can wrap your Set this way:

Set myOrderedSet = new LinkedHashSet(mySet);

If the folder just contains functions then adding the folders to the path at the start of the script will suffice.

addpath('../folder_x/');
addpath('../folder_y/');

If they are Packages, folders starting with a '+' then they also need to be imported.

import package_x.*
import package_y.*

You need to add the package folders parent to the search path.

I assume you mean the size of the bullet at the start of each list item. If that's the case, you can use an image instead of it:

list-style-image:url('bigger.gif');
list-style-type:none;

If you meant the actual size of the li element, then you can change that as normal with width and height.

This should get you started:

R> qplot(hwy, cty, data = mpg) + 
       facet_grid(. ~ manufacturer) + 
       theme(strip.text.x = element_text(size = 8, colour = "orange", angle = 90))

See also this question: How can I manipulate the strip text of facet plots in ggplot2?

If there is a one to one mapping between entity and entity_property you can use entity_id as the identifier.

The typical use is

void* ret = NULL;
pthread_t tid = something; /// change it suitably
if (pthread_join (tid, &ret)) 
   handle_error();
// do something with the return value ret

For this you can simply use the "HttpWebRequest" and "HttpWebResponse" classes in .net.

Below is a sample console app I wrote to demonstrate how easy this is.

using System;
using System.Collections.Generic;
using System.Text;
using System.Net;
using System.IO;

namespace Test
{
    class Program
    {
        static void Main(string[] args)
        {
            string url = "www.somewhere.com";       
            string fileName = @"C:\output.file";

            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
            request.Timeout = 5000;

            try
            {
                using (WebResponse response = (HttpWebResponse)request.GetResponse())
                {
                    using (FileStream stream = new FileStream(fileName, FileMode.Create, FileAccess.Write))
                    {
                        byte[] bytes = ReadFully(response.GetResponseStream());

                        stream.Write(bytes, 0, bytes.Length);
                    }
                }
            }
            catch (WebException)
            {
                Console.WriteLine("Error Occured");
            }
        }

        public static byte[] ReadFully(Stream input)
        {
            byte[] buffer = new byte[16 * 1024];
            using (MemoryStream ms = new MemoryStream())
            {
                int read;
                while ((read = input.Read(buffer, 0, buffer.Length)) > 0)
                {
                    ms.Write(buffer, 0, read);
                }
                return ms.ToArray();
            }
        }
    }
}

Enjoy!

surefire plugins version might be one of the reasons. For me following dependency worked. Please try:

    <!-- https://mvnrepository.com/artifact/org.apache.maven.plugins/maven-surefire-plugin -->
<dependency>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>

In math, ? means FOR ALL.

Unicode character (\u2200, ?).

Tilde expansion is a shell thing. Write the proper pathname (probably /home/yourusername/Desktop/etcetcetc) or use
process.env.HOME + '/Desktop/blahblahblah'

try "configuration properties -> debugging -> environment" and set the PATH variable in run-time

Changing only what's after hash - old browsers

document.location.hash = 'lookAtMeNow';

Changing full URL. Chrome, Firefox, IE10+

history.pushState('data to be passed', 'Title of the page', '/test');

The above will add a new entry to the history so you can press Back button to go to the previous state. To change the URL in place without adding a new entry to history use

history.replaceState('data to be passed', 'Title of the page', '/test');

Try running these in the console now!

According to Dangerously Set innerHTML,

Improper use of the innerHTML can open you up to a cross-site scripting (XSS) attack. Sanitizing user input for display is notoriously error-prone, and failure to properly sanitize is one of the leading causes of web vulnerabilities on the internet.

Our design philosophy is that it should be "easy" to make things safe, and developers should explicitly state their intent when performing “unsafe” operations. The prop name dangerouslySetInnerHTML is intentionally chosen to be frightening, and the prop value (an object instead of a string) can be used to indicate sanitized data.

After fully understanding the security ramifications and properly sanitizing the data, create a new object containing only the key __html and your sanitized data as the value. Here is an example using the JSX syntax:

function createMarkup() {
    return {
       __html: 'First · Second'    };
 }; 

<div dangerouslySetInnerHTML={createMarkup()} /> 

Read more about it using below link:

documentation: React DOM Elements - dangerouslySetInnerHTML.

The following code worked for me.

$('input[name="chkGender[]"]:checked').length;

I assume that since you're using an XML declaration, you're not worrying about IE or older browsers.

So you can use display:table-cell and display:table-row like so:

<?xml version="1.0" encoding="UTF-8" ?>

    <title></title>
    <style type="text/css">
        .toolbar ul {
            display:table-row;
        }
        .toolbar ul li
        {
            display: table-cell;
            height: 100px;
            list-style-type: none;
            margin: 10px;
            vertical-align: middle;
        }
        .toolbar ul li a {
            display:table-cell;
            vertical-align: middle;
            height:100px;
            border: solid 1px black;
        }
        .toolbar ul li.button a {
            height:50px;
            border: solid 1px black;
        }
    </style>
</head>
<body>
    <div class="toolbar">
        <ul>
            <li><a href="#">first item<br />
                first item<br />
                first item</a></li>
            <li><a href="#">second item</a></li>
            <li><a href="#">last item</a></li>
