The answer posted to this question as an example taken from Microsoft's MSDN is nice however it doesn't directly demonstrate where the error comes from if it doesn't come from the TRY Block. I prefer this example with a very minor update to the RAISERROR Message within the CATCH Block stating that the error is from the CATCH Block. I demonstrate this in the gif as well.

BEGIN TRY
    /* RAISERROR with severity 11-19 will cause execution
     |  to jump to the CATCH block.
    */
    RAISERROR ('Error raised in TRY block.', -- Message text.
               5, -- Severity. /* Severity Levels Less Than 11 do not jump to the CATCH block */
               1 -- State.
               );
END TRY

BEGIN CATCH
    DECLARE @ErrorMessage  NVARCHAR(4000);
    DECLARE @ErrorSeverity INT;
    DECLARE @ErrorState    INT;

    SELECT 
        @ErrorMessage  = ERROR_MESSAGE(),
        @ErrorSeverity = ERROR_SEVERITY(),
        @ErrorState    = ERROR_STATE();

    /* Use RAISERROR inside the CATCH block to return error
     | information about the original error that caused
     | execution to jump to the CATCH block
    */
    RAISERROR ('Caught Error in Catch', --@ErrorMessage, /* Message text */
               @ErrorSeverity,                           /* Severity     */
               @ErrorState                               /* State        */
               );
END CATCH;

Yes it is, there have to be boolean expresion after IF. Here you have a direct link. I hope it helps. GL!

Before I get to my reiterated answer; I am confessing that the only answer I would accept here is this one by KM. above. I down voted the other answers because none of them actually answered the question asked or they were not adequate. PRINT output does indeed show up in the Message window, but that is not what was asked at all.

Why doesn't the PRINT statement output show during my Stored Procedure execution?
The short version of this answer is that you are sending your sproc's execution over to the SQL server and it isn't going to respond until it is finished with the whole transaction. Here is a better answer located at this external link.

• For even more opinions/observations focus your attention on this SO post here.
• Specifically look at this answer of the same post by Phil_factor (Ha ha! Love the SQL humor)
• Regarding the suggestion of using RAISERROR WITH NOWAIT look at this answer of the same post by JimCarden

Don't do these things

1. Some people are under the impression that they can just use a GO statement after their PRINT statement, but you CANNOT use the GO statement INSIDE of a sproc. So that solution is out.
2. I don't recommend SELECT-ing your print statements because it is just going to muddy your result set with nonsense and if your sproc is supposed to be consumed by a program later, then you will have to know which result sets to skip when looping through the results from your data reader. This is just a bad idea, so don't do it.
3. Another problem with SELECT-ING your print statements is that they don't always show up immediately. I have had different experiences with this for different executions, so don't expect any kind of consistency with this methodology.

Alternative to PRINT inside of a Stored Procedure
Really this is kind of an icky work around in my opinion because the syntax is confusing in the context that it is being used in, but who knows maybe it will be updated in the future by Microsoft. I just don't like the idea of raising an error for the sole purpose of printing out debug info...

It seems like the only way around this issue is to use, as has been explained numerous times already RAISERROR WITH NOWAIT. I am providing an example and pointing out a small problem with this approach:

ALTER
--CREATE 
    PROCEDURE [dbo].[PrintVsRaiseErrorSprocExample]
AS
BEGIN
    SET NOCOUNT ON;

    -- This will print immediately
    RAISERROR ('RE Start', 0, 1) WITH NOWAIT
    SELECT 1;

    -- Five second delay to simulate lengthy execution
    WAITFOR DELAY '00:00:05'

    -- This will print after the five second delay
    RAISERROR ('RE End', 0, 1) WITH NOWAIT
    SELECT 2;
END

GO

EXEC [dbo].[PrintVsRaiseErrorSprocExample]

Both SELECT statement results will only show after the execution is finished and the print statements will show in the order shown above.

Potential problem with this approach
Let's say you have both your PRINT statement and RAISERROR statement one after the other, then they both print. I'm sure this has something to do with buffering, but just be aware that this can happen.

ALTER
--CREATE 
    PROCEDURE [dbo].[PrintVsRaiseErrorSprocExample2]
AS
BEGIN
    SET NOCOUNT ON;

    -- Both the PRINT and RAISERROR statements will show
    PRINT 'P Start';
    RAISERROR ('RE Start', 0, 1) WITH NOWAIT
    SELECT 1;

    WAITFOR DELAY '00:00:05'

    -- Both the PRINT and RAISERROR statements will show
    PRINT 'P End'
    RAISERROR ('RE End', 0, 1) WITH NOWAIT
    SELECT 2;
END

GO

EXEC [dbo].[PrintVsRaiseErrorSprocExample2]

Therefore the work around here is, don't use both PRINT and RAISERROR, just choose one over the other. If you want your output to show during the execution of a sproc then use RAISERROR WITH NOWAIT.

Had the exact same error in a procedure. It turns out the user running it (a technical user in our case) did not have sufficient rigths to create a temporary table.

EXEC sp_addrolemember 'db_ddladmin', 'username_here';

did the trick

You can use RETURN to stop execution of a stored procedure immediately. Quote taken from Books Online:

Exits unconditionally from a query or procedure. RETURN is immediate and complete and can be used at any point to exit from a procedure, batch, or statement block. Statements that follow RETURN are not executed.

Out of paranoia, I tried yor example and it does output the PRINTs and does stop execution immediately.

See TRY...CATCH (Transact-SQL)

 CREATE PROCEDURE [dbo].[PL_GEN_PROVN_NO1]        
       @GAD_COMP_CODE  VARCHAR(2) =NULL, 
       @@voucher_no numeric =null output 
       AS         
   BEGIN  

     begin try 
         -- your proc code
     end try

     begin catch
          -- what you want to do in catch
     end catch    
  END -- proc end

Have you verified that there is in fact a row where Staff_Id = @PersonID? What you've posted works fine in a test script, assuming the row exists. If you comment out the insert statement, then the error is raised.

set nocount on

create table Timesheet_Hours (Staff_Id int, BookedHours int, Posted_Flag bit)

insert into Timesheet_Hours (Staff_Id, BookedHours, Posted_Flag) values (1, 5.5, 0)

declare @PersonID int
set @PersonID = 1

IF EXISTS    
    (
    SELECT 1    
    FROM Timesheet_Hours    
    WHERE Posted_Flag = 1    
        AND Staff_Id = @PersonID    
    )    
    BEGIN
        RAISERROR('Timesheets have already been posted!', 16, 1)
        ROLLBACK TRAN
    END
ELSE
    IF NOT EXISTS
        (
        SELECT 1
        FROM Timesheet_Hours
        WHERE Staff_Id = @PersonID
        )
        BEGIN
            RAISERROR('Default list has not been loaded!', 16, 1)
            ROLLBACK TRAN
        END
    ELSE
        print 'No problems here'

drop table Timesheet_Hours

What you probably need to do is redirect the user after the POST / Form Handler script has been ran.

In PHP this is done like so...

<?php
// ... Handle $_POST data, maybe insert it into a database.
// Ok, $_POST data has been handled, redirect the user
header('Location:success.php');
die();
?>

... this should allow you to refresh the page without getting that "Send Data Again" warning.

You can even redirect to the same page (if that's what you're posting to) as the POST variables will not be sent in the headers (and thus not be there to re-POST on refresh)

This is how I did it.

Step 1: Install Java 11

You can download Java 11 dmg for mac from here: https://www.oracle.com/technetwork/java/javase/downloads/jdk11-downloads-5066655.html

Step 2: After installation of Java 11. Confirm installation of all versions. Type the following command in your terminal.

/usr/libexec/java_home -V

Step 3: Edit .bash_profile

sudo nano ~/.bash_profile

Step 4: Add 11.0.1 as default. (Add below line to bash_profile file).

export JAVA_HOME=$(/usr/libexec/java_home -v 11.0.1)

to switch to any version

export JAVA_HOME=$(/usr/libexec/java_home -v X.X.X)

Now Press CTRL+X to exit the bash. Press 'Y' to save changes.

Step 5: Reload bash_profile

source ~/.bash_profile

Step 6: Confirm current version of Java

java -version

Everything is possible only if there is enough time to research :)

What I got to do is like having people that I iterate into a ui:repeat and display names and other fields in inputs. But one of fields was singleSelect - A and depending on it value update another input - B. even ui:repeat do not have id I put and it appeared in the DOM tree

<ui:repeat id="peopleRepeat"
value="#{myBean.people}"
var="person" varStatus="status">

Than the ids in the html were something like:

myForm:peopleRepeat:0:personType
myForm:peopleRepeat:1:personType

Than in the view I got one method like:

<p:ajax event="change"
listener="#{myBean.onPersonTypeChange(person, status.index)}"/>

And its implementation was in the bean like:

String componentId = "myForm:peopleRepeat" + idx + "personType";
PrimeFaces.current().ajax().update(componentId);

So this way I updated the element from the bean with no issues. PF version 6.2

Good luck and happy coding :)

In general, one doesn't expand out log(a + b); you just deal with it as is. That said, there are occasionally circumstances where it makes sense to use the following identity:

log(a + b) = log(a * (1 + b/a)) = log a + log(1 + b/a)

(In fact, this identity is often used when implementing log in math libraries).

On Excel 2010 try this:

1. select the cell you want to check if is used somewhere in a formula;
2. Formulas -> Trace Dependents (on Formula Auditing menu)

The command

echo this ^& that

works as expected, outputing

this & that

The command

echo this ^& that > tmp

also works, writing the string to file "tmp". However, before a pipe

echo this ^& that | clip

the ^ is interpreted completely differently. It tries to write the output of the two commands "echo this" and "that" to the pipe. The echo will work then "that" will give an error. Saying

echo this ^& echo that | clip

will put the strings "this" and "that" on the clipboard.

Without the ^:

echo this & echo that | clip

the first echo will write to the console and only the second echo's output will be piped to clip (similarly for "> tmp" redirection). So, when output is being redirected, the ^ does not quote the & but instead causes it to be applied before the redirection rather than after.

To pipe an &, you have to quote it twice

echo this ^^^& that | clip

If you put the string in a variable

set m=this ^& that

then

set m

will output

m=this & that

but the obvious

echo %m%

fails because, after Windows substitutes the variable, resulting in

echo this & that

it parses this as a new command and tries to execute "that".

In a batch file, you can use delayed expansion:

setlocal enableDelayedExpansion
echo !m!

To output to a pipe, we have to replace all &s in the variable value with ^&, which we can do with the %VAR:FROM=TO% syntax:

echo !m:^&=^^^&! | clip

On the command line, "cmd /v" enables delayed expansion:

cmd /v /c echo !m!

This works even when writing to a pipe

cmd /v /c echo !m! | clip

Simple.

The easiest way is to handle all of your database interactions in its own module that you export to your routes. If your route has no context of the database then SQL can't touch it anyway.

If you want to use jQuery you can use .replaceAll()

I got this error for a stupid mistake, the variable name in the @PathVariable wasn't matching the one in the @RequestMapping

For example

@RequestMapping(value = "/whatever/{**contentId**}", method = RequestMethod.POST)
public … method(@PathVariable Integer **contentID**){
}

Probably the best way to do this (which may or may not be possible in your case depending on your situation) is to move to C++ and use it as 'a better C'. You can use C++ without using classes, templates, operator overloading or other advanced features.

This will give you a variant of C with function overloading and default parameters (and whatever other features you chose to use). You just have to be a little disciplined if you're really serious about using only a restricted subset of C++.

A lot of people will say it's a terrible idea to use C++ in this way, and they might have a point. But's it's just an opinion; I think it's valid to use features of C++ that you're comfortable with without having to buy into the whole thing. I think a significant part of the reason for the sucess of C++ is that it got used by an awful lot of programmers in it's early days in exactly this way.

Where seek is the size of the file you want in bytes - 1.

dd if=/dev/zero of=filename bs=1 count=1 seek=1048575

Besides the way suggested in the "possible duplicate", the other main way of getting around this problem is for the array itself (or at least a template of one) to be supplied by the caller, who will hopefully know the concrete type and can thus safely create the array.

This is the way methods like ArrayList.toArray(T[]) are implemented. I'd suggest you take a look at that method for inspiration. Better yet, you should probably be using that method anyway as others have noted.

In CSS3 there is a simple but brilliant hack for that:

font-size:calc(12px + 1.5vw);

This is because the static part of calc() defines the minimum. Even though the dynamic part might shrink to something near 0.

console.log has nothing to do with jQuery. It is a common object/method provided by debuggers (including the Chrome debugger and Firebug) that allows a script to log data (or objects in most cases) to the JavaScript console.

The following method takes the object and any properties to filter out.

function removeObjectKeys(obj, ...keysToRemove) {
  let mObject = { ...obj }
  for (let key of keysToRemove) {
    const { [String(key)]: _, ...rest } = mObject
    mObject = { ...rest }
  }
  return mObject
}
    
const obj = { 123: "hello", 345: "world", 567: "and kitty" };
const filtered = removeObjectKeys(obj, 123);
console.log(filtered);

const twoFiltered = removeObjectKeys(obj, 345, 567);
console.log(twoFiltered);

When i start reading it i did notice that you guys forgot about abvious think like type of to check if we have int, string, null or Boolean. So i think gettype() should be as 1st answer. Explain: So if we have $test = [1,w2,3.45,sasd]; we start test it

foreach ($test as $value) {
        $check = gettype($value);
        if($check == 'integer'){
            echo "This var is int\r\n";
        }
        if($check != 'integer'){
            echo "This var is {$check}\r\n";
        }
}

And output:

> This var is int 
> This var is string 
> This var is double 
> This var is string

I think this is easiest way to check if our var is int, string, double or Boolean.

The CSV "standard" (such as it is) does not dictate how comments should be handled, no, it's up to the application to establish a convention and stick with it.

To test only the IMagick PHP extension (not the full ImageMagick suite), save the following as a PHP file (testImagick.php) and then run it from console: php testImagick.php

<?php
$image = new Imagick();
$image->newImage(1, 1, new ImagickPixel('#ffffff'));
$image->setImageFormat('png');
$pngData = $image->getImagesBlob();
echo strpos($pngData, "\x89PNG\r\n\x1a\n") === 0 ? 'Ok' : 'Failed';
echo "\n";

The -Wno-unused-variable switch usually does the trick. However, that is a very useful warning indeed if you care about these things in your project. It becomes annoying when GCC starts to warn you about things not in your code though.

I would recommend you keeping the warning on, but use -isystem instead of -I for include directories of third-party projects. That flag tells GCC not to warn you about the stuff you have no control over.

For example, instead of -IC:\\boost_1_52_0, say -isystem C:\\boost_1_52_0.

Hope it helps. Good Luck!

For me, None of the above solutions worked. I was migrating from two older mac's to a new mac, trying to get release/debug profiles working on Xcode WITHOUT Xcode auto managing them.

The solution for me was that when I went and created the two new Certificates, i ALSO had to go into my provisioning profiles, and add (under both the distribution and dev) the new certificates to the provisioning profiles so recognized them. After doing this & downloading, xcode removed all errors and it is good to go.

Hope this helps someone!

If you need something quick and dirty, you can just use PayPal's "Buy" buttons and drop them on your pages. These will take people off-site to PayPal where they can pay with a PayPal account or a credit card. This is free and super easy to implement.

If you want something a bit nicer where people pay on-site with their credit card, then you would want to look into one of those 3rd part payment providers. None of them (that I'm aware of) are completely free. All will have a per-transaction fee, and most will have a monthly fee as well.

Personally I've worked with Authorize.NET and PayPal Website Payments Pro. Both have great APIs and sample code that you can hook into via PHP easily enough.

I would suggest using numpy's sort, as it is anyway what pandas is doing in background:

import numpy as np
np.sort(df.A.unique())

But doing all in pandas is valid as well.

For Microsoft office 2013

"Last but one" of a non empty row:

=OFFSET(Sheet5!$C$1,COUNTA(Sheet5!$C:$C)-2,0)

"Last" non empty row:

=OFFSET(Sheet5!$C$1,COUNTA(Sheet5!$C:$C)-1,0)

you could use either PowerISO or WinRAR

Newer kernels (e.g. the latest Ubuntu kernels) come with the new 'perf' tools (apt-get install linux-tools) AKA perf_events.

These come with classic sampling profilers (man-page) as well as the awesome timechart!

The important thing is that these tools can be system profiling and not just process profiling - they can show the interaction between threads, processes and the kernel and let you understand the scheduling and I/O dependencies between processes.

This is a simple way of doing something.

    @Override
        public void onBackPressed() {
            // do what you want to do when the "back" button is pressed.
            startActivity(new Intent(Activity.this, MainActivity.class));
            finish();
        }

I think there might be more elaborate ways of going about it, but I like simplicity. For example, I used the template above to make the user sign out of the application AND THEN go back to another activity of my choosing.

Try this:

 >>> f = open('goodlines.txt')
 >>> mylist = f.readlines()

open() function returns a file object. And for file object, there is no method like splitlines() or split(). You could use dir(f) to see all the methods of file object.

Using the new nested query syntax

with q(name, id, parent_id, parent_name) as (
    select 
      t1.name, t1.id, 
      null as parent_id, null as parent_name 
    from t1
    where t1.id = 1
  union all
    select 
      t1.name, t1.id, 
      q.id as parent_id, q.name as parent_name 
    from t1, q
    where t1.parent_id = q.id
)
select * from q

The Process static class has a method GetProcessesByName() which you can use to search through running processes. Just search for any other process with the same executable name.

In the absense of cache control directives that specify otherwise, a 301 redirect defaults to being cached without any expiry date.

That is, it will remain cached for as long as the browser's cache can accommodate it. It will be removed from the cache if you manually clear the cache, or if the cache entries are purged to make room for new ones.

You can verify this at least in Firefox by going to about:cache and finding it under disk cache. It works this way in other browsers including Chrome and the Chromium based Edge, though they don't have an about:cache for inspecting the cache.

In all browsers it is still possible to override this default behavior using caching directives, as described below:

If you don't want the redirect to be cached

This indefinite caching is only the default caching by these browsers in the absence of headers that specify otherwise. The logic is that you are specifying a "permanent" redirect and not giving them any other caching instructions, so they'll treat it as if you wanted it indefinitely cached.

The browsers still honor the Cache-Control and Expires headers like with any other response, if they are specified.

You can add headers such as Cache-Control: max-age=3600 or Expires: Thu, 01 Dec 2014 16:00:00 GMT to your 301 redirects. You could even add Cache-Control: no-cache so it won't be cached permanently by the browser or Cache-Control: no-store so it can't even be stored in temporary storage by the browser.

Though, if you don't want your redirect to be permanent, it may be a better option to use a 302 or 307 redirect. Issuing a 301 redirect but marking it as non-cacheable is going against the spirit of what a 301 redirect is for, even though it is technically valid. YMMV, and you may find edge cases where it makes sense for a "permanent" redirect to have a time limit. Note that 302 and 307 redirects aren't cached by default by browsers.

If you previously issued a 301 redirect but want to un-do that

If people still have the cached 301 redirect in their browser they will continue to be taken to the target page regardless of whether the source page still has the redirect in place. Your options for fixing this include:

• A simple solution is to issue another redirect back again.

  If the browser is directed back to a same URL a second time during a redirect, it should fetch it from the origin again instead of redirecting again from cache, in an attempt to avoid a redirect loop. Comments on this answer indicate this now works in all major browsers - but there may be some minor browsers where it doesn't.

• If you don't have control over the site where the previous redirect target went to, then you are out of luck. Try and beg the site owner to redirect back to you.

Prevention is better than cure - avoid a 301 redirect if you are not sure you want to permanently de-commission the old URL.

I was doing this mistake

ForEach ($server in $servers) {
$OS = Get-WmiObject win32_operatingsystem -ComputerName $server
}

Which, of course, couldn't be passed, because output of the server in a csv file was @{Name=hv1g.contoso.com}

I had to call the property from csv file like this $server.Name

ForEach ($server in $servers) {
$OS = Get-WmiObject win32_operatingsystem -ComputerName $server.Name
}

It fixed my issue.

I am trying to avoid using VBA. But if has to be, then it has to be:)

There is quite simple UDF for you:

Function myCountIf(rng As Range, criteria) As Long
    Dim ws As Worksheet

    For Each ws In ThisWorkbook.Worksheets
        myCountIf = myCountIf + WorksheetFunction.CountIf(ws.Range(rng.Address), criteria)
    Next ws
End Function

and call it like this: =myCountIf(I:I,A13)

P.S. if you'd like to exclude some sheets, you can add If statement:

Function myCountIf(rng As Range, criteria) As Long
    Dim ws As Worksheet

    For Each ws In ThisWorkbook.Worksheets
        If ws.name <> "Sheet1" And ws.name <> "Sheet2" Then
            myCountIf = myCountIf + WorksheetFunction.CountIf(ws.Range(rng.Address), criteria)
        End If
    Next ws
End Function

UPD:

I have four "reference" sheets that I need to exclude from being scanned/searched. They are currently the last four in the workbook

Function myCountIf(rng As Range, criteria) As Long
    Dim i As Integer

    For i = 1 To ThisWorkbook.Worksheets.Count - 4
        myCountIf = myCountIf + WorksheetFunction.CountIf(ThisWorkbook.Worksheets(i).Range(rng.Address), criteria)
    Next i
End Function

If you use the Eclipse "New Android Project" wizard in a recent ADT bundle, you'll automatically get tabs implemented as a Fragments. This makes the conversion of your application to the tablet format much easier in the future.

For simple single screen layouts you may still use Activity.

I used Sorin Comanescu's solution, but hit a problem when trying to get the selected value. My combobox was a toolstrip combobox. I used the "combobox" property, which exposes a normal combobox.

I had a

 Dictionary<Control, string> controls = new Dictionary<Control, string>();

Binding code (Sorin Comanescu's solution - worked like a charm):

 controls.Add(pictureBox1, "Image");
 controls.Add(dgvText, "Text");
 cbFocusedControl.ComboBox.DataSource = new BindingSource(controls, null);
 cbFocusedControl.ComboBox.ValueMember = "Key";
 cbFocusedControl.ComboBox.DisplayMember = "Value";

The problem was that when I tried to get the selected value, I didn't realize how to retrieve it. After several attempts I got this:

 var control = ((KeyValuePair<Control, string>) cbFocusedControl.ComboBox.SelectedItem).Key

Hope it helps someone else!

maybe there are some unmerged paths in your git repository that you have to resolve before stashing.

To make the solution by @flion look really great, you could adjust the center point for that icon so it doesn't wobble up and down. This looks right for me at a small font size:

.glyphicon-refresh.spinning {
  transform-origin: 48% 50%;
}

Note for NVidia users: GeForce Experience silently overrides some hotkeys (for example Alt+F7) and ReSharper stops to handle them. So you need to disable or remap nvidia hotkeys first.

Alongside nmaier's answer, as he said you'll always receive code 1006. However, if you were to somehow theoretically receive other codes, here is code to display the results (via RFC6455).

The only way to access classes in the default package is from another class in the default package. In that case, don't bother to import it, just refer to it directly.

I've been struggling recently with the implementation of complex parameter switches in a batch file so here is the result of my research. None of the provided answers are fully safe, examples:

"%1"=="-?" will not match if the parameter is enclosed in quotes (needed for file names etc.) or will crash if the parameter is in quotes and has spaces (again often seen in file names)

@ECHO OFF
SETLOCAL
echo.
echo starting parameter test...
echo.
rem echo First parameter is %1
if "%1"=="-?" (echo Condition is true, param=%1) else (echo Condition is false, param=%1)
C:\>test.bat -?

starting parameter test...

Condition is true, param=-?

C:\>test.bat "-?"

starting parameter test...

Condition is false, param="-?"

Any combination with square brackets [%1]==[-?] or [%~1]==[-?] will fail in case the parameter has spaces within quotes:

@ECHO OFF
SETLOCAL 
echo.
echo starting parameter test...
echo.
echo First parameter is %1
if [%~1]==[-?] (echo Condition is true, param=%1) else (echo Condition is false, param=%1)

C:\>test.bat "long file name"

starting parameter test...

First parameter is "long file name"
file was unexpected at this time.

The proposed safest solution "%~1"=="-?" will crash with a complex parameter that includes text outside the quotes and text with spaces within the quotes:

@ECHO OFF
SETLOCAL 
echo.
echo starting parameter test...
echo.
echo First parameter is %1
if "%~1"=="-?" (echo Condition is true, param=%1) else (echo Condition is false, param=%1)

C:\>test.bat -source:"long file name"

starting parameter test...

First parameter is -source:"long file name"
file was unexpected at this time.

The only way to ensure all above scenarios are covered is to use EnableDelayedExpansion and to pass the parameters by reference (not by value) using variables. Then even the most complex scenario will work fine:

@ECHO OFF
SETLOCAL EnableDelayedExpansion
echo.
echo starting parameter test...
echo.
echo First parameter is %1
:: we assign the parameter to a variable to pass by reference with delayed expansion
set "var1=%~1"
echo var1 is !var1!
:: we assign the value to compare with to a second variable to pass by reference with delayed expansion
set "var2=-source:"c:\app images"\image.png"
echo var2 is !var2!
if "!var1!"=="!var2!" (echo Condition is true, param=!var1!) else (echo Condition is false, param=!var1!)
C:\>test.bat -source:"c:\app images"\image.png

starting parameter test...

First parameter is -source:"c:\app images"\image.png
var1 is -source:"c:\app images"\image.png
var2 is -source:"c:\app images"\image.png
Condition is true, param=-source:"c:\app images"\image.png

C:\>test.bat -source:"c:\app images"\image1.png

starting parameter test...

First parameter is -source:"c:\app images"\image1.png
var1 is -source:"c:\app images"\image1.png
var2 is -source:"c:\app images"\image.png
Condition is false, param=-source:"c:\app images"\image1.png

C:\>test.bat -source:"c:\app images\image.png"

starting parameter test...

First parameter is -source:"c:\app images\image.png"
var1 is -source:"c:\app images\image.png"
var2 is -source:"c:\app images"\image.png
Condition is false, param=-source:"c:\app images\image.png"

This answer is based on Kassem's answer but it also handles two-digit years. I submitted an edit to Kassem's answer, but in case it wasn't approved, I'm also submitting this as a separate answer.

        var monthIndex=formatItems.indexOf("mm");
        var dayIndex=formatItems.indexOf("dd");
        var yearIndex=formatItems.indexOf("yyyy");
        var year = parseInt(dateItems[yearIndex]); 
        // adjust for 2 digit year
        if (year < 100) { year += 2000; }

I'm using XML to carry the result back from the php on the server to the webpage and I have had the same behaviour.

In my case the reason was , that the closing tag did not match the opening tag.

<?php
....
header("Content-Type: text/xml");
echo "<?xml version=\"1.0\" encoding=\"utf-8\"?>
    <result>
        <status>$status</status>
        <OPENING_TAG>$message</CLOSING_TAG>
    </result>";
?>

I would like to make this answer for meaningful, so the same kind of erroneous user can enjoy without feel any hassle.

Actually, i was getting the same error but for the different reason, in my case I didn't used any kind of quoted, still getting the same error like expected <block end>, but found BlockMappingStart.

I have solved it by fixing, the Alignment issue inside the same .yml file.

If we don't manage the proper 'tab-space(Keyboard key)' for maintaining successor or ancestor then we have to phase such kind of things.

Now i am doing well.

You can also increase it via the VM arguments in your IDE. In my case, I am using Tomcat v7.0 which is running on Eclipse. To do this, double click on your server (Tomcat v7.0). Click the 'Open launch configuration' link. Go to the 'Arguments' tab. Add -XX:MaxPermSize=512m to the VM arguments list. Click 'Apply' and then 'OK'. Restart your server.

Use beginUpdates and endUpdates to insert a new cell when the button clicked.

As @vadian said in comment, begin/endUpdates has no effect for a single insert/delete/move operation

First of all, append data in your tableview array

Yourarray.append([labeltext])  

Then update your table and insert a new row

// Update Table Data
tblname.beginUpdates()
tblname.insertRowsAtIndexPaths([
NSIndexPath(forRow: Yourarray.count-1, inSection: 0)], withRowAnimation: .Automatic)
tblname.endUpdates()

This inserts cell and doesn't need to reload the whole table but if you get any problem with this, you can also use tableview.reloadData()

Swift 3.0

tableView.beginUpdates()
tableView.insertRows(at: [IndexPath(row: yourArray.count-1, section: 0)], with: .automatic)
tableView.endUpdates()

Objective-C

[self.tblname beginUpdates];
NSArray *arr = [NSArray arrayWithObject:[NSIndexPath indexPathForRow:Yourarray.count-1 inSection:0]];
[self.tblname insertRowsAtIndexPaths:arr withRowAnimation:UITableViewRowAnimationAutomatic];
[self.tblname endUpdates];

The default locations of Chrome's profile directory are defined at http://www.chromium.org/user-experience/user-data-directory. For Chrome on Mac, it's

~/Library/Application\ Support/Google/Chrome/Default

The actual location can be different, by setting the --user-data-dir=path/to/directory flag.
If only one user is registered in Chrome, look in the Default/Extensions subdirectory. Otherwise, look in the <profile user name>/Extensions directory.

If that didn't help, you can always do a custom search.

1. Go to chrome://extensions/, and find out the ID of an extension (32 lowercase letters) (if not done already, activate "Developer mode" first).

   

2. Open the terminal, cd to the directory which is most likely a parent of your Chrome profile (if unsure, try ~ then /).

3. Run find . -type d -iname "<EXTENSION ID HERE>", for example:

   find . -type d -iname jifpbeccnghkjeaalbbjmodiffmgedin
   

   Result:

   

In the SQL-92 Standard, COUNT(*) specifically means "the cardinality of the table expression" (could be a base table, `VIEW, derived table, CTE, etc).

I guess the idea was that COUNT(*) is easy to parse. Using any other expression requires the parser to ensure it doesn't reference any columns (COUNT('a') where a is a literal and COUNT(a) where a is a column can yield different results).

In the same vein, COUNT(*) can be easily picked out by a human coder familiar with the SQL Standards, a useful skill when working with more than one vendor's SQL offering.

Also, in the special case SELECT COUNT(*) FROM MyPersistedTable;, the thinking is the DBMS is likely to hold statistics for the cardinality of the table.

Therefore, because COUNT(1) and COUNT(*) are semantically equivalent, I use COUNT(*).

If you are dealing with a web service call using the Axis framework, there is a much simpler answer. If all want is for your client to be able to call the SSL web service and ignore SSL certificate errors, just put this statement before you invoke any web services:

System.setProperty("axis.socketSecureFactory", "org.apache.axis.components.net.SunFakeTrustSocketFactory");

The usual disclaimers about this being a Very Bad Thing to do in a production environment apply.

I found this at the Axis wiki.

Check if you access internet through a proxy, and then your add internet proxy address to yum configuration.

add

proxy=http://ip:port

to /etc/yum.conf

While a regexp would suit here just fine, I'll present you with an alternative method. It might be a tad faster than the equivalent regexp, but life's all about choices (...or something).

$length = strlen($urlString);
for ($i=0; $i<$length; i++) {
  if ($urlString[$i] === '?') {
    $urlString[$i+1] = '';
    break;
  }
}

Weird, I know.

If your environment doesn't allow overwriting with >, use pipe | and tee instead as follows:

echo "text" | tee 'Users/Name/Desktop/TheAccount.txt'

Note this will also print to the stdout. In case this is unwanted, you can redirect the output to /dev/null as follows:

echo "text" | tee 'Users/Name/Desktop/TheAccount.txt' > /dev/null

other.component.ts

So final correct solution is :

import { Component, OnInit } from '@angular/core';
import { Location } from '@angular/common';
import { Router } from '@angular/router'; 

/* 'router' it must be in small case */

    @Component({
      selector: 'app-other',
      templateUrl: './other.component.html',
      styleUrls: ['./other.component.css']
    })

    export class OtherComponent implements OnInit {

        public href: string = "";
        url: string = "asdf";

        constructor(private router : Router) {} // make variable private so that it would be accessible through out the component

        ngOnInit() {
            this.href = this.router.url;
            console.log(this.router.url);
        }
    }

In AndroidManifest.xml, set android:theme="@android:style/Theme.NoTitleBar.Fullscreen"in application tag.

Individual activities can override the default by setting their own theme attributes.

There is often the tip to use 'echo.'

But that is slow, and it could fail with an error message, as cmd.exe will search first for a file named 'echo' (without extension) and only when the file doesn't exists it outputs an empty line.

You could use echo(. This is approximately 20 times faster, and it works always. The only drawback could be that it looks odd.

More about the different ECHO:/\ variants is at DOS tips: ECHO. FAILS to give text or blank line.

I had a similar problem -- no matter what I did I couldn't get the tabsize to stick at 2, even though it is in my user settings -- that ended up being due to the EditorConfig extension. It looks for a .editorconfig file in your current working directory and, if it doesn't find one (or the one it finds doesn't specify root=true), it will continue looking at parent directories until it finds one.

Turns out I had a .editorconfig in a parent directory of the dir I put all my new code projects in, and it specified a tabSize of 4. Deleting that file fixed my issue.

Your variable declarations and their scope are correct. The problem you are facing is that the first AJAX request may take a little bit time to finish. Therefore, the second URL will be filled with the value of sID before the its content has been set. You have to remember that AJAX request are normally asynchronous, i.e. the code execution goes on while the data is being fetched in the background.

You have to nest the requests:

$.getJSON("https://prod.api.pvp.net/api/lol/eune/v1.1/summoner/by-name/"+input+"?api_key=API_KEY_HERE"  , function(name){   obj = name;   // sID is only now available!   sID = obj.id;   console.log(sID); }); 

• Put the second request into a function
• and let it accept sID as a parameter, so you don't have to declare it globally anymore! (Global variables are almost always evil!)
• Remove sID and obj variables - name.id is sufficient unless you really need the other variables outside the function.

$.getJSON("https://prod.api.pvp.net/api/lol/eune/v1.1/summoner/by-name/"+input+"?api_key=API_KEY_HERE"  , function(name){   // We don't need sID or obj here - name.id is sufficient   console.log(name.id);    doSecondRequest(name.id); });  /// TODO Choose a better name function doSecondRequest(sID) {   $.getJSON("https://prod.api.pvp.net/api/lol/eune/v1.2/stats/by-summoner/" + sID + "/summary?api_key=API_KEY_HERE", function(stats){         console.log(stats);   }); }

to Vilx-:

var table = row.parentNode;
while ( table && table.tagName != 'TABLE' )
    table = table.parentNode;

and what if row.parentNode is TBODY?

You should check it out first, and after that do while by .tBodies, probably

This feature was added in 1.45, demoed here.

Launch the command palette Ctrl+Shift+P, run Publish to Github, and follow the prompt. You will be given the choice between a private and public repository, so be careful that you choose the right one.

It may ask you to login to github. It will then prompt for the repo name (defaults to the name of the folder), and for creating a .gitignore file (defaults to empty .gitignore). Just hit enter if you are fine with the defaults. When you are done it should give you a popup notification in the bottom right with a link to the repo https://github.com/<username>/<reponame>

Minor warning: if your project already has a .gitignore file in it this process will overwrite it

Yes. The only way would be to drop the constraint with an Alter table then recreate it.

ALTER TABLE <Table_Name>
DROP CONSTRAINT <constraint_name>

ALTER TABLE <Table_Name>
ADD CONSTRAINT <constraint_name> PRIMARY KEY (<Column1>,<Column2>)

There is a jQuery plugin for the general case of scrolling to a DOM element, but if performance is an issue (and when is it not?), I would suggest doing it manually. This involves two steps:

1. Finding the position of the element you are scrolling to.
2. Scrolling to that position.

quirksmode gives a good explanation of the mechanism behind the former. Here's my preferred solution:

function absoluteOffset(elem) {
    return elem.offsetParent && elem.offsetTop + absoluteOffset(elem.offsetParent);
}

It uses casting from null to 0, which isn't proper etiquette in some circles, but I like it :) The second part uses window.scroll. So the rest of the solution is:

function scrollToElement(elem) {
    window.scroll(absoluteOffset(elem));
}

Voila!

Use Compressor (Image compression library). Visit zetbaitsu/Compressor for code and documentation.

1. add dependency in gradle (app level)

   dependencies {
       implementation 'id.zelory:compressor:3.0.0'
   }
   

2. To Compress Image use one of these approaches:

• Compress Image File:

        val compressedImageFile = Compressor.compress(context, actualImageFile)
  

• Compress Image File to Bitmap:

        val compressedImageFile = Compressor.compress(context, actualImageFile)
        val bitmap = BitmapFactory.decodeFile(compressedImageFile.path)
  

Your problem comes from the 32/64 bit version of your JDK/JRE... Your shared lib is searched for a 32 bit version.

Your default JDK is a 32 bit version. Try to install a 64 bit one by default and relaunch your `.sh file.

If you're looking for "in-place" editing of a ListView's contents (specifically the subitems of a ListView in details view mode), you'll need to implement this yourself, or use a third-party control.

By default, the best you can achieve with a "standard" ListView is to set it's LabelEdit property to true to allow the user to edit the text of the first column of the ListView (assuming you want to allow a free-format text edit).

Some examples (including full source-code) of customized ListView's that allow "in-place" editing of sub-items are:

C# Editable ListView
In-place editing of ListView subitems

A simple way of doing this is via nargin (N arguments in). The downside is you have to make sure that your argument list and the nargin checks match.

It is worth remembering that all inputs are optional, but the functions will exit with an error if it calls a variable which is not set. The following example sets defaults for b and c. Will exit if a is not present.

function [ output_args ] = input_example( a, b, c )
if nargin < 1
  error('input_example :  a is a required input')
end

if nargin < 2
  b = 20
end

if nargin < 3
  c = 30
end
end

Take a look at this link: http://dev.mysql.com/doc/refman/5.0/en/mysql-indexes.html

How they work is too broad of a subject to cover in one SO post.

Here is one of the best explanations of indexes I have seen. Unfortunately it is for SQL Server and not MySQL. I'm not sure how similar the two are...

I had the same problem and it was because PHPMailer realized the server supported STARTTLS so it tried to automatically upgrade the connection to an encrypted connection. My mail server is on the same subnet as the web server within my network which is all behind our domain firewalls so I'm not too worried about using encryption (plus the generated emails don't contain sensitive data anyway).

So what I went ahead and did was change the SMTPAutoTLS to false in the class.phpmailer.php file.

/**
 * Whether to enable TLS encryption automatically if a server supports it,
 * even if `SMTPSecure` is not set to 'tls'.
 * Be aware that in PHP >= 5.6 this requires that the server's certificates are valid.
 * @var boolean
 */
public $SMTPAutoTLS = false;

I found easier to do it like this:

export GOROOT=$HOME/go
export GOPATH=$GOROOT/bin
export PATH=$PATH:$GOPATH

This is because label is an inline element, and is therefore only as big as the text it contains.

The possible is to display your label as a block element like this:

#formItem label {
    display: block;
    text-align: center;
    line-height: 150%;
    font-size: .85em;
}

However, if you want to use the label on the same line with other elements, you either need to set display: inline-block; and give it an explicit width (which doesn't work on most browsers), or you need to wrap it inside a div and do the alignment in the div.

I am currently using Android Studio 1.4.

For importing and adding libraries, I used the following flow ->

1. Press **Alt+Ctr+Shift+S** or Go to **File --> Project** Structure to open up the Project Structure Dialog Box.

2. Click on **Modules** to which you want to link the JAR to and Go to the Dependency Tab.

3. Click on "**+**" Button to pop up Choose Library Dependency.

4. Search/Select the dependency and rebuild the project.

I used the above approach to import support v4 and v13 libraries.

I hope this is helpful and clears up the flow.

This question is old, but now the best is use google Gson.

An example to get custom viewModel.

Class<CustomViewModel<String>> clazz = new GenericClass<CustomViewModel<String>>().getRawType();
CustomViewModel<String> viewModel = viewModelProvider.get(clazz);

Generic type class

class GenericClass<T>(private val rawType: Class<*>) {

    constructor():this(`$Gson$Types`.getRawType(object : TypeToken<T>() {}.getType()))

    fun getRawType(): Class<T> {
        return rawType as Class<T>
    }
}

Here's a clean and concise solution:

function argsToArray() {_x000D_
  return Object.values(arguments);_x000D_
}_x000D_
_x000D_
// example usage_x000D_
console.log(_x000D_
  argsToArray(1, 2, 3, 4, 5)_x000D_
  .map(arg => arg*11)_x000D_
);

Object.values( ) will return the values of an object as an array, and since arguments is an object, it will essentially convert arguments into an array, thus providing you with all of an array's helper functions such as map, forEach, filter, etc.

There are multiple methods to do that:

Method 1:

alert($('.checkbox_class_here:checked').size());

Method 2:

alert($('input[name=checkbox_name]').attr('checked'));

Method 3:

alert($(":checkbox:checked").length);

I did it in perl based on the most popular answer by ProdigySim's 2nd method. I had to add a break equivalent in perl, last, right after the print $i . " \n"; to avoid outputting the primes twice.

#!/bin/perl
use strict;

for(my $i=2; $i < 100; $i++){

    my $prime = 1;

    for (my $j=2; $j*$j<=$i; $j++){
        if ($i % $j == 0){
            $prime = 0;
            last;
        }
        if($prime) {
            print $i . " \n";
            last;
        }
    }

}

I had mostly the same problem and ended up a a different solution that makes this type of problem trivial to query.

I have a table of sensor data (1 minute data from about 30 sensors)

SensorReadings->(timestamp,value,idSensor)

and I have a sensor table that has lots of mostly static stuff about the sensor but the relevant fields are these:

Sensors->(idSensor,Description,tvLastUpdate,tvLastValue,...)

The tvLastupdate and tvLastValue are set in a trigger on inserts to the SensorReadings table. I always have direct access to these values without needing to do any expensive queries. This does denormalize slightly. The query is trivial:

SELECT idSensor,Description,tvLastUpdate,tvLastValue 
FROM Sensors

I use this method for data that is queried often. In my case I have a sensor table, and a large event table, that have data coming in at the minute level AND dozens of machines are updating dashboards and graphs with that data. With my data scenario the trigger-and-cache method works well.

update:

I found the terms of use from Google Map:

Section 10.5

No caching or storage.

I don't think you can, and CSS is supposed to describe how the page looks not what it does, so even if you could, it's not really how you should be using it.

Perhaps you should think about using JQuery to apply common functionality to your form components?

If you ONLY want to have a conda installation. Just remove all of the other python paths from your PATH variable.

Leaving only:

C:\ProgramData\Anaconda3
C:\ProgramData\Anaconda3\Scripts
C:\ProgramData\Anaconda3\Library\bin

This allows you to just use pip install * and it will install straight into your conda installation.

To AutoComplete TextBox Control in C#.net windows application using 
wamp mysql database...

here is my code..

AutoComplete();

write this **AutoComplete();** text in form-load event..

private void Autocomplete()
    {
        try
        {
            MySqlConnection cn = new MySqlConnection("server=localhost;
database=databasename;user id=root;password=;charset=utf8;");
            cn.Open();
            MySqlCommand cmd = new MySqlCommand("SELECT distinct Column_Name
     FROM table_Name", cn);
            DataSet ds = new DataSet();
            MySqlDataAdapter da = new MySqlDataAdapter(cmd);
            da.Fill(ds, "table_Name");
            AutoCompleteStringCollection col = new   
            AutoCompleteStringCollection();
            int i = 0;
            for (i = 0; i <= ds.Tables[0].Rows.Count - 1; i++)
            {
                col.Add(ds.Tables[0].Rows[i]["Column_Name"].ToString());

            }
            textBox1.AutoCompleteSource = AutoCompleteSource.CustomSource;
            textBox1.AutoCompleteCustomSource = col;
            textBox1.AutoCompleteMode = AutoCompleteMode.Suggest;
            cn.Close();
        }
        catch (Exception ex)
        {

While yourTextField.requestFocus() is A solution, it is not the best since in the official Java documentation this is discourage as the method requestFocus() is platform dependent.

The documentation says:

Note that the use of this method is discouraged because its behavior is platform dependent. Instead we recommend the use of requestFocusInWindow().

Use yourJTextField.requestFocusInWindow() instead.

Try this :

<button> @Html.ActionLink(" ", "DeletePhoto", "PhotoAndVideo", new { id = item.Id }, new { @class = "modal-link1", @OnClick = "return confirm('Are you sure you to delete this Record?');" })</button>

The OO solution for this is to create a ratio class. It wouldn't take any extra code (would save some), would be significantly cleaner/clearer, and would give you some extra refactorings letting you clean up code outside this class as well.

Actually I think someone recommended returning a structure, which is close enough but hides the intent that this needs to be a fully thought-out class with constructor and a few methods, in fact, the "method" that you originally mentioned (as returning the pair) should most likely be a member of this class returning an instance of itself.

I know your example was just an "Example", but the fact is that unless your function is doing way more than any function should be doing, if you want it to return multiple values you are almost certainly missing an object.

Don't be afraid to create these tiny classes to do little pieces of work--that's the magic of OO--you end up breaking it down until every method is very small and simple and every class small and understandable.

Another thing that should have been an indicator that something was wrong: in OO you have essentially no data--OO isn't about passing around data, a class needs to manage and manipulate it's own data internally, any data passing (including accessors) is a sign that you may need to rethink something..

Are you creating a very large table (hundreds of rows and columns)? If so, table-layout: fixed; is a good idea, as the browser only needs to read the first row in order to compute and render the entire table, so it loads faster.

But if not, I would suggest dumping table-layout: fixed; and changing your css as follows:

table th, table td{
border: 1px solid #000;
width:20px;  //or something similar   
}

table td.wideRow, table th.wideRow{
width: 300px;
}

When using "jsonp", you would basically be returning data wrapped in a function call, something like

jsonpCallback([{"id":1,"value":"testing"},{"id":2,"value":"test again"}])
where the function/callback name is 'jsonpCallback'.

If you have access to the server, please first verify that the response is in the correct "jsonp" format

For such a response coming from the server, you would need to specify something in the ajax call as well, something like

jsonpCallback: "jsonpCallback",  in your ajax call

Please note that the name of the callback does not need to be "jsonpCallback" its just a name picked as an example but it needs to match the name(wrapping) done on the server side.

My first guess to your problem is that the response from the server is not what it should be.

Dim M As Range

    Set M = Selection

If application.CountIf(M, "<>0") < 2 Then
    MsgBox "Nothing selected, please select first BOM or Next BOM"
Else

'Your code here

End If

From experience I just learned you could do:

If Selection.Rows.Count < 2 
Then End If`

Clarification to be provided a bit later (right now I'm working)

The metacharacter \b is an anchor like the caret and the dollar sign. It matches at a position that is called a "word boundary". This match is zero-length.

There are three different positions that qualify as word boundaries:

• Before the first character in the string, if the first character is a word character.
• After the last character in the string, if the last character is a word character.
• Between two characters in the string, where one is a word character and the other is not a word character.

Simply put: \b allows you to perform a "whole words only" search using a regular expression in the form of \bword\b. A "word character" is a character that can be used to form words. All characters that are not "word characters" are "non-word characters".

In all flavors, the characters [a-zA-Z0-9_] are word characters. These are also matched by the short-hand character class \w. Flavors showing "ascii" for word boundaries in the flavor comparison recognize only these as word characters.

\w stands for "word character", usually [A-Za-z0-9_]. Notice the inclusion of the underscore and digits.

\B is the negated version of \b. \B matches at every position where \b does not. Effectively, \B matches at any position between two word characters as well as at any position between two non-word characters.

\W is short for [^\w], the negated version of \w.

To change just the colour of the player, simply address the audio tag in your css file, for instance on one of my sites the player became invisible (white on white) so I added:

audio {
    background-color: #95B9C7;
}

This changed the player to light blue.

uint16_t is unsigned 16-bit integer.

unsigned short int is unsigned short integer, but the size is implementation dependent. The standard only says it's at least 16-bit (i.e, minimum value of UINT_MAX is 65535). In practice, it usually is 16-bit, but you can't take that as guaranteed.

Note:

1. If you want a portable unsigned 16-bit integer, use uint16_t.
2. inttypes.h and stdint.h are both introduced in C99. If you are using C89, define your own type.
3. uint16_t may not be provided in certain implementation(See reference below), but unsigned short int is always available.

Reference: C11(ISO/IEC 9899:201x) §7.20 Integer types

For each type described herein that the implementation provides) shall declare that typedef name and define the associated macros. Conversely, for each type described herein that the implementation does not provide, shall not declare that typedef name nor shall it define the associated macros. An implementation shall provide those types described as ‘‘required’’, but need not provide any of the others (described as ‘optional’’).

Assuming you have the menuStrip object and the menu is only one level deep, use:

ToolStripMenuItem item = menuStrip.Items
    .OfType<ToolStripMenuItem>()
    .SelectMany(it => it.DropDownItems.OfType<ToolStripMenuItem>())
    .SingleOrDefault(n => n.Name == "MyMenu");

For deeper menu levels add more SelectMany operators in the statement.

if you want to search all menu items in the strip then use

ToolStripMenuItem item = menuStrip.Items
    .Find("MyMenu",true)
    .OfType<ToolStripMenuItem>()
    .Single();

However, make sure each menu has a different name to avoid exception thrown by key duplicates.

To avoid exceptions you could use FirstOrDefault instead of SingleOrDefault / Single, or just return a sequence if you might have Name duplicates.

The easiest way is to add a type to the variable that is receiving the value, like this:

var value: string = (event.target as any).value;

Or you could cast the value property as well as event.target like this:

var value = ((event.target as any).value as string);

Edit:

Lastly, you can define what EventTarget.value is in a separate .d.ts file. However, the type will have to be compatible where it's used elsewhere, and you'll just end up using any again anyway.

globals.d.ts

interface EventTarget {
    value: any;
}

Unfortunately there's a simple answer to this question, and it's "No"

Adm-zip has problems just compressing an existing archive https://github.com/cthackers/adm-zip/issues/64 as well as corruption with compressing binary files.

node-archiver is the only one that seems to work well to compress but it doesn't have any uncompress functionality.

The following code snippet resolved my issue. Thought this might be useful to others.

var strEnc = this.$.txtSearch.value.replace(/\s/g, "-");_x000D_
strEnc = strEnc.replace(/-/g, " ");

Rather using default encodeURIComponent my first line of code is converting all spaces into hyphens using regex pattern /\s\g and the following line just does the reverse, i.e. converts all hyphens back to spaces using another regex pattern /-/g. Here /g is actually responsible for finding all matching characters.

When I am sending this value to my Ajax call, it traverses as normal spaces or simply %20 and thus gets rid of double-encoding.

IEnumerable introduces quite a number of extensions to it which helps you to pass your own delegate and invoking the resultant from the IEnumerable back. Most of them are by nature of type Func

The Func takes an argument T and returns TResult.

In case of

Where - Func : So it takes IEnumerable of T and Returns a bool. The where will ultimately returns the IEnumerable of T's for which Func returns true.

So if you have 1,5,3,6,7 as IEnumerable and you write .where(r => r<5) it will return a new IEnumerable of 1,3.

Any - Func basically is similar in signature but returns true only when any of the criteria returns true for the IEnumerable. In our case, it will return true as there are few elements present with r<5.

Exists - Predicate on the other hand will return true only when any one of the predicate returns true. So in our case if you pass .Exists(r => 5) will return true as 5 is an element present in IEnumerable.

You can use one of Java template engines. I love this method because you are separating your logic from the view.

Java 8+:

<dependency>
  <groupId>com.github.spullara.mustache.java</groupId>

  <version>0.8.18</version>
</dependency>

Example template file:

{{#items}}
Name: {{name}}
Price: {{price}}
  {{#features}}
  Feature: {{description}}
  {{/features}}
{{/items}}

Might be powered by some backing code:

public class Context {
  List<Item> items() {
    return Arrays.asList(
      new Item("Item 1", "$19.99", Arrays.asList(new Feature("New!"), new Feature("Awesome!"))),
      new Item("Item 2", "$29.99", Arrays.asList(new Feature("Old."), new Feature("Ugly.")))
    );
  }

  static class Item {
    Item(String name, String price, List<Feature> features) {
      this.name = name;
      this.price = price;
      this.features = features;
    }
    String name, price;
    List<Feature> features;
  }

  static class Feature {
    Feature(String description) {
       this.description = description;
    }
    String description;
  }
}

And would result in:

Name: Item 1
Price: $19.99
  Feature: New!
  Feature: Awesome!
Name: Item 2
Price: $29.99
  Feature: Old.
  Feature: Ugly.

The answers are correct but don't mention how to sync code between the public repo and the fork.

Here is the full workflow (we've done this before open sourcing React Native):

First, duplicate the repo as others said (details here):

Create a new repo (let's call it private-repo) via the Github UI. Then:

git clone --bare https://github.com/exampleuser/public-repo.git
cd public-repo.git
git push --mirror https://github.com/yourname/private-repo.git
cd ..
rm -rf public-repo.git

Clone the private repo so you can work on it:

git clone https://github.com/yourname/private-repo.git
cd private-repo
make some changes
git commit
git push origin master

To pull new hotness from the public repo:

cd private-repo
git remote add public https://github.com/exampleuser/public-repo.git
git pull public master # Creates a merge commit
git push origin master

Awesome, your private repo now has the latest code from the public repo plus your changes.

Finally, to create a pull request private repo -> public repo:

Use the GitHub UI to create a fork of the public repo (the small "Fork" button at the top right of the public repo page). Then:

git clone https://github.com/yourname/the-fork.git
cd the-fork
git remote add private_repo_yourname https://github.com/yourname/private-repo.git
git checkout -b pull_request_yourname
git pull private_repo_yourname master
git push origin pull_request_yourname

Now you can create a pull request via the Github UI for public-repo, as described here.

Once project owners review your pull request, they can merge it.

Of course the whole process can be repeated (just leave out the steps where you add remotes).

For Version 78.0.3904.87, OS = Windows 7, 64 bit PC

Steps:

1. Press F12
2. Select Network Tab
3. Select XHR
4. Under Name --> you can see all the XHR requests made.
5. To view Request Headers of a particular XHR request, click on that request. All details about that XHR request will appear on right hand side.

SOA records are present on all servers further up the hierarchy, over which the domain owner has NO control, and they all in effect point to the one authoritative name server under control of the domain owner.

The SOA record on the authoritative server itself is, on the other hand, not strictly needed for resolving that domain, and can contain bogus info (or hidden primary, or otherwise restricted servers) and should not be relied on to determine the authoritative name server for a given domain.

You need to query the server that is authoritative for the top level domain to obtain reliable SOA information for a given child domain.

(The information about which server is authoritative for which TLD can be queried from the root name servers).

When you have reliable information about the SOA from the TLD authoritative server, you can then query the primary name server itself authoritative (the one thats in the SOA record on the gTLD nameserver!) for any other NS records, and then proceed with checking all those name servers you've got from querying the NS records, to see if there is any inconsistency for any other particular record, on any of those servers.

This all works much better/reliable with linux and dig than with nslookup/windows.

You can match those three groups separately, and make sure that they all present. Also, [^\w] seems a bit too broad, but if that's what you want you might want to replace it with \W.

It's always worth grouping elements into sections that are relevant. In your case, a parent element that contains two columns;

1. icon
2. text.

    float:left;
    font-size:0.6em;
}
.text p span {
    color:#666;

Swift 4:

override func viewWillAppear(_ animated: Bool) {
    NotificationCenter.default.addObserver(self, selector: #selector(deviceRotated), name: UIDevice.orientationDidChangeNotification, object: nil)
}

override func viewWillDisappear(_ animated: Bool) {
    NotificationCenter.default.removeObserver(self, name: UIDevice.orientationDidChangeNotification, object: nil)
}

@objc func deviceRotated(){
    if UIDevice.current.orientation.isLandscape {
        //Code here
    } else {
        //Code here
    }
}

A lot of answers dont help when needing to detect across various view controllers. This one does the trick.

If you just need a selector for Javascript purposes (like I did), you might just want to use a href attribute instead of a class or id:

Just do this:

<a href="#foo">Link</a>

Markdown will not ignore or remove the href attribute like it does with classes and ids.

So in your Javascript or jQuery you can then do:

$('a[href$="foo"]').click(function(event) {

    ... do your thing ...

    event.preventDefault();
});

At least this works in my version of Markdown...

something I found today, after reading this question and continuing on my googlesurf:

echo $path;

Merge a branch into new one (squash) and remove the files not needed:

git checkout master
git checkout -b <branch>
git merge --squash <source-branch-with-many-commits>
git reset HEAD <not-needed-file-1>
git checkout -- <not-needed-file-1>
git reset HEAD <not-needed-file-2>
git checkout -- <not-needed-file-2>
git commit

There is a easy way to do it.

    NSArray *myArray = @[@"5",@"4",@"3",@"2",@"1"];
    NSMutableArray *myNewArray = [[NSMutableArray alloc] init]; //this object is going to be your new array with inverse order.
    for(int i=0; i<[myNewArray count]; i++){
        [myNewArray insertObject:[myNewArray objectAtIndex:i] atIndex:0];
    }
    //other way to do it
    for(NSString *eachValue in myArray){
        [myNewArray insertObject:eachValue atIndex:0];
    }

    //in both cases your new array will look like this
    NSLog(@"myNewArray: %@", myNewArray);
    //[@"1",@"2",@"3",@"4",@"5"]

I hope this helps.

Unlike languages that employ 'true' lexical scoping, Python opts to have specific 'namespaces' for variables, whether it be global, nonlocal, or local. It could be argued that making developers consciously code with such namespaces in mind is more explicit, thus more understandable. I would argue that such complexities make the language more unwieldy, but I guess it's all down to personal preference.

Here are some examples regarding global:-

>>> global_var = 5
>>> def fn():
...     print(global_var)
... 
>>> fn()
5
>>> def fn_2():
...     global_var += 2
...     print(global_var)
... 
>>> fn_2()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 2, in fn_2
UnboundLocalError: local variable 'global_var' referenced before assignment
>>> def fn_3():
...     global global_var
...     global_var += 2
...     print(global_var)
... 
>>> fn_3()
7

The same patterns can be applied to nonlocal variables too, but this keyword is only available to the latter Python versions.

In case you're wondering, nonlocal is used where a variable isn't global, but isn't within the function definition it's being used. For example, a def within a def, which is a common occurrence partially due to a lack of multi-statement lambdas. There's a hack to bypass the lack of this feature in the earlier Pythons though, I vaguely remember it involving the use of a single-element list...

Note that writing to variables is where these keywords are needed. Just reading from them isn't ambiguous, thus not needed. Unless you have inner defs using the same variable names as the outer ones, which just should just be avoided to be honest.

according to mysql documentation none of these works! People pay attention! so we will upload test.sql into the test_db type this into the shell:

mysql --user=user_name --password=yourpassword test_db < d:/test.sql

In VS 2019

1. in the main VS menu bar click: View -> Test Explorer
2. Right-click your test method in Test Explorer -> Debug
3. Click the additional output link as seen in the screenshot below.

You can use:

• Debug.WriteLine
• Console.WriteLine
• TestContext.WriteLine

all will log to the additional output window.

You need to use ScriptManager.RegisterStartupScript for Ajax.

protected void ButtonPP_Click(object sender, EventArgs e) {     if (radioBtnACO.SelectedIndex < 0)     {         string csname1 = "PopupScript";          var cstext1 = new StringBuilder();         cstext1.Append("alert('Please Select Criteria!')");          ScriptManager.RegisterStartupScript(this, GetType(), csname1,             cstext1.ToString(), true);     } } 

Type 'line numbers' into the Quick Launch textbox (top right VS 2015), and it'll take you right where you need to be (tick Line Numbers checkbox).

You can use display: flex to position an element to the bottom, but I do not think you want to use flex in this case, as it will affect all of your elements.

To position an element to the bottom using flex try this:

.container {
  display: flex;
}

.button {
  align-self: flex-end;
}

Your best bet is to set position: absolute to the button and set it to bottom: 0, or you can place the button outside the container and use negative transform: translateY(-100%) to bring it in the container like this:

.content {
    height: 400px;
    background: #000;
    color: #fff;
}
.button {
    transform: translateY(-100%);
    display: inline-block;
}

You must use an integer value for the CURLOPT_SSLVERSION value, not a string as listed above

Try this:

curl_setopt ($setuploginurl, CURLOPT_SSLVERSION, 6); //Integer NOT string TLS v1.2

http://php.net/manual/en/function.curl-setopt.php

value should be an integer for the following values of the option parameter: CURLOPT_SSLVERSION

One of

CURL_SSLVERSION_DEFAULT (0)
CURL_SSLVERSION_TLSv1 (1)
CURL_SSLVERSION_SSLv2 (2)
CURL_SSLVERSION_SSLv3 (3)
CURL_SSLVERSION_TLSv1_0 (4)
CURL_SSLVERSION_TLSv1_1 (5)
CURL_SSLVERSION_TLSv1_2 (6).

You can use Underscore:

var x = [[1], [2], [3, 4]];

_.flatten(x); // => [1, 2, 3, 4]

In order to obtain the string in a Text widget one can simply use get method defined for Text which accepts 1 to 2 arguments as start and end positions of characters, text_widget_object.get(start, end=None). If only start is passed and end isn't passed it returns only the single character positioned at start, if end is passed as well, it returns all characters in between positions start and end as string.

There are also special strings, that are variables to the underlying Tk. One of them would be "end" or tk.END which represents the variable position of the very last char in the Text widget. An example would be to returning all text in the widget, with text_widget_object.get('1.0', 'end') or text_widget_object.get('1.0', 'end-1c') if you don't want the last newline character.

Demo

See below demonstration that selects the characters in between the given positions with sliders:

try:
    import tkinter as tk
except:
    import Tkinter as tk


class Demo(tk.LabelFrame):
    """
    A LabeFrame that in order to demonstrate the string returned by the
    get method of Text widget, selects the characters in between the
    given arguments that are set with Scales.

        tk.LabelFrame.__init__(self, master, *args, **kwargs)

HTML:

<input id="myField" type="text" name="email"/>

JavaScript:

// getting the value
var email = $("#myField").val();

// setting the value
$("#myField").val( "new value here" );

I know this question has been answered long time ago, but I would like to add a small thing.

To everyone having the same error, make sure to add this permission in you manifest file:

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

IMPORTANT to use the CAPITAL letters for CAMERA, as I had the permission with small letters and it didn't work.

The simplest way of doing this would be to add

include_directories(${CMAKE_SOURCE_DIR}/inc)
link_directories(${CMAKE_SOURCE_DIR}/lib)

add_executable(foo ${FOO_SRCS})
target_link_libraries(foo bar) # libbar.so is found in ${CMAKE_SOURCE_DIR}/lib

The modern CMake version that doesn't add the -I and -L flags to every compiler invocation would be to use imported libraries:

add_library(bar SHARED IMPORTED) # or STATIC instead of SHARED
set_target_properties(bar PROPERTIES
  IMPORTED_LOCATION "${CMAKE_SOURCE_DIR}/lib/libbar.so"
  INTERFACE_INCLUDE_DIRECTORIES "${CMAKE_SOURCE_DIR}/include/libbar"
)

set(FOO_SRCS "foo.cpp")
add_executable(foo ${FOO_SRCS})
target_link_libraries(foo bar) # also adds the required include path

If setting the INTERFACE_INCLUDE_DIRECTORIES doesn't add the path, older versions of CMake also allow you to use target_include_directories(bar PUBLIC /path/to/include). However, this no longer works with CMake 3.6 or newer.

The best and convenient approach is calling fragment instance and send data at that time. every fragment by default have instance method

For example : if your fragment name is MyFragment

so you will call your fragment from activity like this :

getSupportFragmentManager().beginTransaction().add(R.id.container, MyFragment.newInstance("data1","data2"),"MyFragment").commit();

*R.id.container is a id of my FrameLayout

so in MyFragment.newInstance("data1","data2") you can send data to fragment and in your fragment you get this data in MyFragment newInstance(String param1, String param2)

public static MyFragment newInstance(String param1, String param2) {
        MyFragment fragment = new MyFragment();
        Bundle args = new Bundle();
        args.putString(ARG_PARAM1, param1);
        args.putString(ARG_PARAM2, param2);
        fragment.setArguments(args);
        return fragment;
    }

and then in onCreate method of fragment you'll get the data:

@Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        if (getArguments() != null) {
            mParam1 = getArguments().getString(ARG_PARAM1);
            mParam2 = getArguments().getString(ARG_PARAM2);
        }
    }

so now mParam1 have data1 and mParam2 have data2

now you can use this mParam1 and mParam2 in your fragment.

How about this? (year 2015)

1) Get a custom marker image.

var imageObj = new Image();
    imageObj.src = "/markers/blank_pin.png"; 

2) Create a canvas in RAM and draw this image on it

imageObj.onload = function(){
    var canvas = document.createElement('canvas');
    var context = canvas.getContext("2d");
    context.drawImage(imageObj, 0, 0);
}

3) Write anything above it

context.font = "40px Arial";
context.fillText("54", 17, 55);

4) Get raw data from canvas and provide it to Google API instead of URL

var image = {
    url: canvas.toDataURL(),
 };
 new google.maps.Marker({
    position: position,
    map: map,
    icon: image
 });

Full code:

function addComplexMarker(map, position, label, callback){
    var canvas = document.createElement('canvas');
    var context = canvas.getContext("2d");
    var imageObj = new Image();
    imageObj.src = "/markers/blank_pin.png";
    imageObj.onload = function(){
        context.drawImage(imageObj, 0, 0);

        //Adjustable parameters
        context.font = "40px Arial";
        context.fillText(label, 17, 55);
        //End

        var image = {
            url: canvas.toDataURL(),
            size: new google.maps.Size(80, 104),
            origin: new google.maps.Point(0,0),
            anchor: new google.maps.Point(40, 104)
        };
        // the clickable region of the icon.
        var shape = {
            coords: [1, 1, 1, 104, 80, 104, 80 , 1],
            type: 'poly'
        };
        var marker = new google.maps.Marker({
            position: position,
            map: map,
            labelAnchor: new google.maps.Point(3, 30),
            icon: image,
            shape: shape,
            zIndex: 9999
        });
        callback && callback(marker)
    };
});

Error is that you are using 'ID' in lower case like 'checkbox1' but when you loop json object its return in upper case. So you need to replace checkbox1 to CHECKBOX1.

In my case :-

var response = jQuery.parseJSON(response);

$.each(response, function(key, value) {
   $.each(value, function(key, value){
        $('#'+key).val(value);
   });
});

Before

  <input type="text" name="abc" id="abc" value="">

I am getting the same error but when i replace the id in html code its work fine.

After

<input type="text" name="abc" id="ABC" value="">

Yes and no.

The server address portion is NOT encrypted since it is used to set up the connection.

This may change in future with encrypted SNI and DNS but as of 2018 both technologies are not commonly in use.

The path, query string etc. are encrypted.

Note for GET requests the user will still be able to cut and paste the URL out of the location bar, and you will probably not want to put confidential information in there that can be seen by anyone looking at the screen.

Without any external tool you can simply accomplish this on Windows 7 or 8, by opening up the Resource monitor and on the CPU or Overview tab right clicking on the process and selecting Suspend Process. The Resource monitor can be started from the Performance tab of the Task manager.

If using reactive forms, you can also disable the entire form or any sub-set of controls in a FormGroup with myFormGroup.disable().

Swift 4 And Above

let str = "Hello iam midhun"

if str.contains("iam") {
  //contains substring
}
else {
  //doesn't contain substring
}

Objective-C

NSString *stringData = @"Hello iam midhun";

if ([stringData containsString:@"iam"]) {
    //contains substring
}
else {
    //doesn't contain substring
}

As mentioned by sombody above, restarting eclipse worked for me for the user defined environment variable. After I restart eclipse IDE, System.getenv() is picking up my environment variable.

Keep in mind that "blind" is a range of conditions - there are some who are legally blind that could read a really large monitor or with magnification help, and then there are those who have no vision at all. I remember a classmate in college who had a special device to magnify books, and special software she could use to magnify a part of the screen. She was working hard to finish college, because her eyesight was getting worse and was going to go away completely.

Programming also has a spectrum of needs - some people are good at cranking out lots and lots of code, and some people are better at looking at the big picture and architecture. I would imagine that given the difficulty imposed by the screen interface, blindness may enhance your ability to get the big picture...

use plt.figure(dpi=1200) before all your plt.plot... and at the end use plt.savefig(... see: http://matplotlib.org/api/pyplot_api.html#matplotlib.pyplot.figure and http://matplotlib.org/api/pyplot_api.html#matplotlib.pyplot.savefig

In the "admin" module of your app package, do register all the databases created in "models" module of the package.

Suppose you have a database class defined in "models" module as:

class myDb1(models.Model):
    someField= models.Charfiled(max_length=100)

so you must register this in the admin module as:

from .models import myDb1
admin.site.register(myDb1)

I hope this resolve the error.

First, make sure you understand, if you need to use Secure FTP (=FTPS, as per your text) or SFTP (as per tag you have used).

Neither is supported by Windows command-line ftp.exe. As you have suggested, you can use WinSCP. It supports both FTPS and SFTP.

Using WinSCP, your batch file would look like (for SFTP):

echo open sftp://ftp_user:[email protected] -hostkey="server's hostkey" >> ftpcmd.dat
echo put c:\directory\%1-export-%date%.csv >> ftpcmd.dat
echo exit >> ftpcmd.dat
winscp.com /script=ftpcmd.dat
del ftpcmd.dat

And the batch file:

winscp.com /log=ftpcmd.log /script=ftpcmd.dat /parameter %1 %date%

Though using all capabilities of WinSCP (particularly providing commands directly on command-line and the %TIMESTAMP% syntax), the batch file simplifies to:

winscp.com /log=ftpcmd.log /command ^
    "open sftp://ftp_user:[email protected] -hostkey=""server's hostkey""" ^
    "put c:\directory\%1-export-%%TIMESTAMP#yyyymmdd%%.csv" ^
    "exit"

For the purpose of -hostkey switch, see verifying the host key in script.

Easier than assembling the script/batch file manually is to setup and test the connection settings in WinSCP GUI and then have it generate the script or batch file for you:

All you need to tweak is the source file name (use the %TIMESTAMP% syntax as shown previously) and the path to the log file.

For FTPS, replace the sftp:// in the open command with ftpes:// (explicit TLS/SSL) or ftps:// (implicit TLS/SSL). Remove the -hostkey switch.

winscp.com /log=ftpcmd.log /command ^
    "open ftps://ftp_user:[email protected] -explicit" ^
    "put c:\directory\%1-export-%%TIMESTAMP#yyyymmdd%%.csv" ^
    "exit"

You may need to add the -certificate switch, if your server's certificate is not issued by a trusted authority.

Again, as with the SFTP, easier is to setup and test the connection settings in WinSCP GUI and then have it generate the script or batch file for you.

See a complete conversion guide from ftp.exe to WinSCP.

You should also read the Guide to automating file transfers to FTP server or SFTP server.

Note to using %TIMESTAMP#yyyymmdd% instead of %date%: A format of %date% variable value is locale-specific. So make sure you test the script on the same locale you are actually going to use the script on. For example on my Czech locale the %date% resolves to ct 06. 11. 2014, what might be problematic when used as a part of a file name.

For this reason WinSCP supports (locale-neutral) timestamp formatting natively. For example %TIMESTAMP#yyyymmdd% resolves to 20170515 on any locale.

A CGI script is a console/shell program. In Windows, when you use a "Command Prompt" window, you execute console programs. When a web server executes a CGI script it provides input to the console/shell program using environment variables or "standard input". Standard input is like typing data into a console/shell program; in the case of a CGI script, the web server does the typing. The CGI script writes data out to "standard output" and that output is sent to the client (the web browser) as a HTML page. Standard output is like the output you see in a console/shell program except the web server reads it and sends it out.

A CGI script can be executed from a browser. The URI typically includes a query string that is provided to the CGI script. If the method is "get" then the query string is provided to the CGI Script in an environment variable called QUERY_STRING. If the method is "post" then the query string is provided to the CGI Script using standard input (the CGI Script reads the query string from standard input).

An early use of CGI scripts was to process forms. In the beginning of HTML, HTML forms typically had an "action" attribute and a button designated as the "submit" button. When the submit button is pushed the URI specified in the "action" attribute would be sent to the server with the data from the form sent as a query string. If the "action" specifies a CGI script then the CGI script would be executed and it then produces a HTML page.

RFC 3875 "The Common Gateway Interface (CGI)" partially defines CGI using C, as in saying that environment variables "are accessed by the C library routine getenv() or variable environ".

If you are developing a CGI script using C/C++ and use Microsoft Visual Studio to do that then you would develop a console program.

You can simply use Apache Commons Lang:

result = ObjectUtils.compare(firstComparable, secondComparable)

It is because Ajax is asynchronous, the success or the error function will be called later, when the server answer the client. So, just move parts depending on the result into your success function like that :

jQuery.ajax({

            type:"post",
            dataType:"json",
            url: myAjax.ajaxurl,
            data: {action: 'submit_data', info: info},
            success: function(data) {
                successmessage = 'Data was succesfully captured';
                $("label#successmessage").text(successmessage);
            },
            error: function(data) {
                successmessage = 'Error';
                $("label#successmessage").text(successmessage);
            },
        });

        $(":input").val('');
        return false;

You can also do

rake db:rollback

if you have not added any data to the tables.Then edit the migration file by adding the email column to it and then call

rake db:migrate

This will work if you have rails 3.1 onwards installed in your system.

Much simpler way of doing it is change let the change in migration file be as it is. use

$rake db:migrate:redo

This will roll back the last migration and migrate it again.

Based on previous solutions, I have created bookmark with JavaScript code:

javascript: { var toAppend = "trvhpqi=" + (new Date()).getTime(); var links = document.getElementsByTagName("link"); for (var i = 0; i < links.length;i++) { var link = links[i]; if (link.rel === "stylesheet") { if (link.href.indexOf("?") === -1) { link.href += "?" + toAppend; } else { if (link.href.indexOf("trvhpqi") === -1) { link.href += "&" + toAppend; } else { link.href = link.href.replace(/trvhpqi=\d{13}/, toAppend)} }; } } }; void(0);

Image from Firefox:

What does it do?

It reloads CSS by adding query string params (as solutions above):

• Content/Site.css becomes Content/Site.css?trvhpqi=1409572193189 (adds date)
• Content/Site.css?trvhpqi=1409572193189 becomes Content/Site.css?trvhpqi=1409572193200 (date changes)
• http://fonts.googleapis.com/css?family=Open+Sans:400,300,300italic,400italic,800italic,800,700italic,700,600italic,600&subset=latin,latin-ext becomes http://fonts.googleapis.com/css?family=Open+Sans:400,300,300italic,400italic,800italic,800,700italic,700,600italic,600&subset=latin,latin-ext&trvhpqi=1409572193189 (adds new query string param with date)

Check that the project output path (project properties / Build) is set to bin and not bin\Release or bin\Debug

For some reason IIS (VS development Server or Local IIS) always accesses the libraries from the bin directory (and won't look up for subdirectories)

The varStatus references to LoopTagStatus which has a getIndex() method.

So:

<c:forEach var="tableEntity" items='${requestScope.tables}' varStatus="outer">
   <c:forEach var="rowEntity" items='${tableEntity.rows}' varStatus="inner">            
        <c:out value="${(outer.index * fn:length(tableEntity.rows)) + inner.index}" />
    </c:forEach>
</c:forEach>

How to run Rmd in command with knitr and rmarkdown by multiple commands and then Upload an HTML file to RPubs

Here is a example: load two libraries and run a R command

R -e 'library("rmarkdown");library("knitr");rmarkdown::render("NormalDevconJuly.Rmd")'

R -e 'library("markdown");rpubsUpload("normalDev","NormalDevconJuly.html")'

You can also use interceptors to pass the headers

It can save you a lot of code

axios.interceptors.request.use(config => {
  if (config.method === 'POST' || config.method === 'PATCH' || config.method === 'PUT')
    config.headers['Content-Type'] = 'application/json;charset=utf-8';

  const accessToken = AuthService.getAccessToken();
  if (accessToken) config.headers.Authorization = 'Bearer ' + accessToken;

  return config;
});

I don't like to create a new settings/ directory. I simply add files named settings_dev.py and settings_production.py so I don't have to edit the BASE_DIR. The approach below increase the default structure instead of changing it.

            __init__.py
            templatetag_extras.py
    gulpfile.js
    manage.py
    requirements.txt

I think this:

    settings.py
    settings_dev.py
    settings_production.py

is better than this:

    settings/__init__.py
    settings/base.py
    settings/dev.py
    settings/production.py

This concept applies to other files as well.

I usually place node_modules/ and bower_components/ in the project directory within the default static/ folder.

Sometime a vendor/ directory for Git Submodules but usually I place them in the static/ folder.

You can use the strip() function to remove trailing (and leading) whitespace; passing it an argument will let you specify which whitespace:

for i in range(len(lists)):
    grades.append(lists[i].strip('\n'))

It looks like you can just simplify the whole block though, since if your file stores one ID per line grades is just lists with newlines stripped:

Before

lists = files.readlines()
grades = []

for i in range(len(lists)):
    grades.append(lists[i].split(","))

After

grades = [x.strip() for x in files.readlines()]

(the above is a list comprehension)

Finally, you can loop over a list directly, instead of using an index:

Before

for i in range(len(grades)):
    # do something with grades[i]

After

for thisGrade in grades:
    # do something with thisGrade

This is simple code to do it, I avoided all checks but this is the main idea.

 public String parse(String jsonLine) {
    JsonElement jelement = new JsonParser().parse(jsonLine);
    JsonObject  jobject = jelement.getAsJsonObject();
    jobject = jobject.getAsJsonObject("data");
    JsonArray jarray = jobject.getAsJsonArray("translations");
    jobject = jarray.get(0).getAsJsonObject();
    String result = jobject.get("translatedText").getAsString();
    return result;
}

To make the use more generic - you will find that Gson's javadocs are pretty clear and helpful.

How do I run an executable JAR file? If you have a jar file called Example.jar, follow these rules:

Open a notepad.exe.
Write : java -jar Example.jar.
Save it with the extension .bat.
Copy it to the directory which has the .jar file.
Double click it to run your .jar file.

SQLite has a printf function which does exactly that:

Seems like you posted a new question after you realized that you were dealing with a simpler problem related to size_t. I am glad that you did.

Anyways, You have a .c source file, and most of the code looks as per C standards, except that #include <iostream> and using namespace std;

C equivalent for the built-in functions of C++ standard #include<iostream> can be availed through #include<stdio.h>

1. Replace #include <iostream> with #include <stdio.h>, delete using namespace std;

2. With #include <iostream> taken off, you would need a C standard alternative for cout << endl;, which can be done by printf("\n"); or putchar('\n');
   Out of the two options, printf("\n"); works the faster as I observed.

   When used printf("\n"); in the code above in place of cout<<endl;

   $ time ./thread.exe
   1 2 3 4 5 6 7 8 9 10
   
   real    0m0.031s
   user    0m0.030s
   sys     0m0.030s
   

   When used putchar('\n'); in the code above in place of cout<<endl;

   $ time ./thread.exe
   1 2 3 4 5 6 7 8 9 10
   
   real    0m0.047s
   user    0m0.030s
   sys     0m0.030s

Rather than defining contact_email within app.config, define it in a parameters entry:

parameters:

You should find the call you are making within your controller now works.

Not sure what you are trying to accomplish on your first few lines but you can try this:

$(document).ready(function()
{
    $("#ms_num").attr('maxlength','6');
});

I would like to give one additional answer, while the other ones will suffice in most cases.

I wanted to write a string over multiple lines, but its contents needed to be single-line.

sql="                       \
SELECT c1, c2               \
from Table1, ${TABLE2}      \
where ...                   \
"

I am sorry if this if a bit off-topic (I did not need this for SQL). However, this post comes up among the first results when searching for multi-line shell variables and an additional answer seemed appropriate.

There is a problem with objects such as PACKAGE_BODY:

SELECT DBMS_METADATA.get_ddl(object_Type, object_name, owner) FROM ALL_OBJECTS WHERE OWNER = 'WEBSERVICE';


ORA-31600 invalid input value PACKAGE BODY parameter OBJECT_TYPE in function GET_DDL
ORA-06512: ??  "SYS.DBMS_METADATA", line 4018
ORA-06512: ??  "SYS.DBMS_METADATA", line 5843
ORA-06512: ??  line 1
31600. 00000 -  "invalid input value %s for parameter %s in function %s"
*Cause:    A NULL or invalid value was supplied for the parameter.
*Action:   Correct the input value and try the call again.



SELECT DBMS_METADATA.GET_DDL(REPLACE(object_type,' ','_'), object_name, owner)
  FROM all_OBJECTS 
  WHERE (OWNER = 'OWNER1');

You ca try this SQL

select * from employee where rec_date between '2017-09-01' and '2017-09-11' 

var test_obj = from d in repository.DbPricing

    LetterPaperWeight = d2.LetterPaperWeight
    };

@Kunigami: I think you may be mistaken about Guava's newArrayList method. It does not check whether the Iterable is a List type and simply return the given List as-is. It always creates a new list:

@GwtCompatible(serializable = true)
public static <E> ArrayList<E> newArrayList(Iterable<? extends E> elements) {
  checkNotNull(elements); // for GWT
  // Let ArrayList's sizing logic work, if possible
  return (elements instanceof Collection)
      ? new ArrayList<E>(Collections2.cast(elements))
      : newArrayList(elements.iterator());
}

Based on antoinepairet's comment/example:

Using uib-collapse attribute provides animations: http://plnkr.co/edit/omyoOxYnCdWJP8ANmTc6?p=preview

<nav class="navbar navbar-default" role="navigation">

Ancient..

I see that the question is framed around BS2, but I thought I'd pitch in with a solution for Bootstrap 3 using ng-class solution based on suggestions in ui.bootstrap issue 394:

The only variation from the official bootstrap example is the addition of ng- attributes noted by comments, below:

<nav class="navbar navbar-default" role="navigation">
  <div class="navbar-header">

    <!-- note the ng-init and ng-click here: -->
    <button type="button" class="navbar-toggle" ng-init="navCollapsed = true" ng-click="navCollapsed = !navCollapsed">
      <span class="sr-only">Toggle navigation</span>
      <span class="icon-bar"></span>
      <span class="icon-bar"></span>
      <span class="icon-bar"></span>
    </button>
    <a class="navbar-brand" href="#">Brand</a>
  </div>

  <!-- note the ng-class here -->
  <div class="collapse navbar-collapse" ng-class="{'in':!navCollapsed}">

    <ul class="nav navbar-nav">
    ...

Here is an updated working example: http://plnkr.co/edit/OlCCnbGlYWeO7Nxwfj5G?p=preview (hat tip Lars)

This seems to works for me in simple use cases, but you'll note in the example that the second dropdown is cut off… good luck!

Juste add ShowHeaderWhenEmpty property and set it at true

This solution works for me

It looks like you've just finished step 3. Instead of running a function, you just print out a statement. A function is defined in the following way:

def addstudent():
    print("Student Added.")

then called by writing addstudent().

I would recommend using a while loop for your input. You can define the menu option outside the loop, put the print statement inside the loop, and do while(#valid option is not picked), then put the if statements after the while. Or you can do a while loop and continue the loop if a valid option is not selected.

Additionally, a dictionary is defined in the following way:

my_dict = {key:definition,...}

This target can achieve through different method,

1. Using BaseController

The way I like to set things up, I make a BaseController class that extends Laravel’s own Controller, and set up various global things there. All other controllers then extend from BaseController rather than Laravel’s Controller.

class BaseController extends Controller
{
  public function __construct()
  {
    //its just a dummy data object.
    $user = User::all();

    // Sharing is caring
    View::share('user', $user);
  }
}

2. Using Filter

If you know for a fact that you want something set up for views on every request throughout the entire application, you can also do it via a filter that runs before the request — this is how I deal with the User object in Laravel.

App::before(function($request)
{
  // Set up global user object for views
  View::share('user', User::all());
});

OR

You can define your own filter

Route::filter('user-filter', function() {
    View::share('user', User::all());
});

and call it through simple filter calling.

Update According to Version 5.*

3. Using Middleware

Using the View::share with middleware

Route::group(['middleware' => 'SomeMiddleware'], function(){
  // routes
});



class SomeMiddleware {
  public function handle($request)
  {
    \View::share('user', auth()->user());
  }
}

4. Using View Composer

View Composer also help to bind specific data to view in different ways. You can directly bind variable to specific view or to all views. For Example you can create your own directory to store your view composer file according to requirement. and these view composer file through Service provide interact with view.

View composer method can use different way, First example can look alike:

You could create an App\Http\ViewComposers directory.

Service Provider

namespace App\Providers;
use Illuminate\Support\ServiceProvider;
class ViewComposerServiceProvider extends ServiceProvider {
    public function boot() {
        view()->composer("ViewName","App\Http\ViewComposers\TestViewComposer");
    }
}

After that, add this provider to config/app.php under "providers" section.

TestViewComposer

namespace App\Http\ViewComposers;

use Illuminate\Contracts\View\View;

class TestViewComposer {

    public function compose(View $view) {
        $view->with('ViewComposerTestVariable', "Calling with View Composer Provider");
    }
}

ViewName.blade.php

Here you are... {{$ViewComposerTestVariable}}

This method could help for only specific View. But if you want trigger ViewComposer to all views, we have to apply this single change to ServiceProvider.

namespace App\Providers;
use Illuminate\Support\ServiceProvider;
class ViewComposerServiceProvider extends ServiceProvider {
    public function boot() {
        view()->composer('*',"App\Http\ViewComposers\TestViewComposer");
    }
}

If still something unclear from my side, let me know.

You can extend TextView to set custom fonts as I learned here.

TextViewPlus.java:

package com.example;

import android.content.Context;
import android.content.res.TypedArray;
import android.graphics.Typeface;
import android.util.AttributeSet;
import android.util.Log;
import android.widget.TextView;

public class TextViewPlus extends TextView {
    private static final String TAG = "TextView";

    public TextViewPlus(Context context) {
        super(context);
    }

    public TextViewPlus(Context context, AttributeSet attrs) {
        super(context, attrs);
        setCustomFont(context, attrs);
    }

    public TextViewPlus(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        setCustomFont(context, attrs);
    }

    private void setCustomFont(Context ctx, AttributeSet attrs) {
        TypedArray a = ctx.obtainStyledAttributes(attrs, R.styleable.TextViewPlus);
        String customFont = a.getString(R.styleable.TextViewPlus_customFont);
        setCustomFont(ctx, customFont);
        a.recycle();
    }

    public boolean setCustomFont(Context ctx, String asset) {
        Typeface tf = null;
        try {
        tf = Typeface.createFromAsset(ctx.getAssets(), asset);  
        } catch (Exception e) {
            Log.e(TAG, "Could not get typeface: "+e.getMessage());
            return false;
        }

        setTypeface(tf);  
        return true;
    }

}

attrs.xml: (in res/values)

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <declare-styleable name="TextViewPlus">
        <attr name="customFont" format="string"/>
    </declare-styleable>
</resources>

main.xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:foo="http://schemas.android.com/apk/res/com.example"
    android:orientation="vertical" android:layout_width="fill_parent"
    android:layout_height="fill_parent">

    <com.example.TextViewPlus
        android:id="@+id/textViewPlus1"
        android:layout_height="match_parent"
        android:layout_width="match_parent"
        android:text="@string/showingOffTheNewTypeface"
        foo:customFont="saxmono.ttf">
    </com.example.TextViewPlus>
</LinearLayout>

You would put "saxmono.ttf" in the assets folder.

UPDATE 8/1/13

There are serious memory concerns with this method. See chedabob's comment below.

grep -l hello **/*.{h,cc}

You might want to shopt -s nullglob to avoid error messages if there are no .h or no .cc files.

Simple but usefull way:

$query = $this->db->distinct()->select('order_id')->get_where('tbl_order_details', array('seller_id' => $seller_id));
        return $query;

    @echo off

    (echo this is in the first line) > xy.txt
    (echo this is in the second line) >> xy.txt

    exit

The two >> means that the second line will be appended to the file (i.e. second line will start after the last line of xy.txt).

this is how the xy.txt looks like:

this is in the first line
this is in the second line

Here's yet another way, using pure NumPy, no recursion, no list comprehension, and no explicit for loops. It's about 20% slower than the original answer, and it's based on np.meshgrid.

def cartesian(*arrays):
    mesh = np.meshgrid(*arrays)  # standard numpy meshgrid
    dim = len(mesh)  # number of dimensions
    elements = mesh[0].size  # number of elements, any index will do
    flat = np.concatenate(mesh).ravel()  # flatten the whole meshgrid
    reshape = np.reshape(flat, (dim, elements)).T  # reshape and transpose
    return reshape

For example,

x = np.arange(3)
a = cartesian(x, x, x, x, x)
print(a)

gives

[[0 0 0 0 0]
 [0 0 0 0 1]
 [0 0 0 0 2]
 ..., 
 [2 2 2 2 0]
 [2 2 2 2 1]
 [2 2 2 2 2]]

The problem I was having with the rewrite is that some .htaccess files for Codeigniter, etc come with

RewriteBase /

Which doesn't seem to work in MAMP...at least for me.

Doing a relative import is absolulutely OK! Here's what little 'ol me does:

#first change the cwd to the script path
scriptPath = os.path.realpath(os.path.dirname(sys.argv[0]))
os.chdir(scriptPath)

#append the relative location you want to import from
sys.path.append("../common")

#import your module stored in '../common'
import common.py

My XAML is as below:

<ComboBox Grid.Row="2" Grid.Column="1" Height="25" Width="200" SelectedIndex="0" Name="cmbDeviceDefinitionId">
    <ComboBoxItem Content="United States" Name="US"></ComboBoxItem>
    <ComboBoxItem Content="European Union" Name="EU"></ComboBoxItem>
    <ComboBoxItem Content="Asia Pacific" Name="AP"></ComboBoxItem>
</ComboBox>

The content is showing as text and the name of the WPF combobox. To get the name of the selected item, I have follow this line of code:

ComboBoxItem ComboItem = (ComboBoxItem)cmbDeviceDefinitionId.SelectedItem;
string name = ComboItem.Name;

To get the selected text of a WPF combobox:

string name = cmbDeviceDefinitionId.SelectionBoxItem.ToString();

Use .form-group.required without the space.

.form-group.required .control-label:after {
  content:"*";
  color:red;
}

Edit:

.form-group.required:not(.checkbox) .control-label:after, 
.form-group.required .text:after { /* change .text in whatever class of the text after the checkbox has */
   content:"*";
   color:red;
}

<div class="form-group required">
   <label class="col-md-2 control-label">&#160;</label>
   <div class="col-md-4">
      <div class="checkbox">
         <label class='text'> <!-- use this class -->
            <input class="" id="id_tos" name="tos" required="required" type="checkbox" /> I have read and agree to the Terms of Service
         </label>
      </div>
   </div>
</div>

Ok third edit:

CSS back to what is was

.form-group.required .control-label:after { 
   content:"*";
   color:red;
}

HTML:

<div class="form-group required">
   <label class="col-md-2">&#160;</label> <!-- remove class control-label -->
   <div class="col-md-4">
      <div class="checkbox">
         <label class='control-label'> <!-- use this class as the red * will be after control-label -->
            <input class="" id="id_tos" name="tos" required="required" type="checkbox" /> I have read and agree to the Terms of Service
         </label>
      </div>
   </div>
</div>

Terminology : The difference between TRUE north and Magnetic North is known as "variation" not declination. The difference between what your compass reads and the magnetic heading is known as "deviation" and varies with heading. A compass swing identifies device errors and allows corrections to be applied if the device has correction built in. A magnetic compass will have a deviation card which describes the device error on any heading.

Declination : A term used in Astro navigation : Declination is like latitude. It reports how far a star is from the celestial equator. To find the declination of a star follow an hour circle "straight down" from the star to the celestial equator. The angle from the star to the celestial equator along the hour circle is the star's declination.

Take a look at http://json.org/. It claims a bit different list of escaped characters than Chris proposed.

\"
\\
\/
\b
\f
\n
\r
\t
\u four-hex-digits

Its very simple please use the code below and it will give the difference in that format according to this //3 years 9 months 3 weeks 5 days 15 hours 50 minutes

Date.getFormattedDateDiff = function(date1, date2) {
var b = moment(date1),
  a = moment(date2),
  intervals = ['years','months','weeks','days'],
  out = [];

for(var i=0; i<intervals.length; i++){
  var diff = a.diff(b, intervals[i]);
  b.add(diff, intervals[i]);
  out.push(diff + ' ' + intervals[i]);
 }
 return out.join(', ');
 };

 var today   = new Date(),
 newYear = new Date(today.getFullYear(), 0, 1),
 y2k     = new Date(2000, 0, 1);

 //(AS OF NOV 29, 2016)
 //Time since New Year: 0 years, 10 months, 4 weeks, 0 days
 console.log( 'Time since New Year: ' + Date.getFormattedDateDiff(newYear, today) );

 //Time since Y2K: 16 years, 10 months, 4 weeks, 0 days
 console.log( 'Time since Y2K: ' + Date.getFormattedDateDiff(y2k, today) );

For Bootstrap 4, use the below code:

<div class="mx-auto" style="width: 200px;">
  Centered element
</div>

Storing the virtualenv directory inside git will, as you noted, allow you to deploy the whole app by just doing a git clone (plus installing and configuring Apache/mod_wsgi). One potentially significant issue with this approach is that on Linux the full path gets hard-coded in the venv's activate, django-admin.py, easy_install, and pip scripts. This means your virtualenv won't entirely work if you want to use a different path, perhaps to run multiple virtual hosts on the same server. I think the website may actually work with the paths wrong in those files, but you would have problems the next time you tried to run pip.

The solution, already given, is to store enough information in git so that during the deploy you can create the virtualenv and do the necessary pip installs. Typically people run pip freeze to get the list then store it in a file named requirements.txt. It can be loaded with pip install -r requirements.txt. RyanBrady already showed how you can string the deploy statements in a single line:

# before 15.1.0
virtualenv --no-site-packages --distribute .env &&\
    source .env/bin/activate &&\
    pip install -r requirements.txt

# after deprecation of some arguments in 15.1.0
virtualenv .env && source .env/bin/activate && pip install -r requirements.txt

Personally, I just put these in a shell script that I run after doing the git clone or git pull.

Storing the virtualenv directory also makes it a bit trickier to handle pip upgrades, as you'll have to manually add/remove and commit the files resulting from the upgrade. With a requirements.txt file, you just change the appropriate lines in requirements.txt and re-run pip install -r requirements.txt. As already noted, this also reduces "commit spam".

this works for me

$(window).bind('beforeunload', function() {
      return 'Do you really want to leave?' ;
});

Update:

I am able to get through the issue and now I am able to access the chrome with desired url.

Results of trying the provided solutions:

I tried all the settings as provided above but I was unable to resolve the issue

Explanation regarding the issue:

As per my observation DevToolsActivePort file doesn't exist is caused when chrome is unable to find its reference in scoped_dirXXXXX folder.

Steps taken to solve the issue

1. I have killed all the chrome processes and chrome driver processes.

2. Added the below code to invoke the chrome

   System.setProperty("webdriver.chrome.driver","pathto\\chromedriver.exe");    
   ChromeOptions options = new ChromeOptions();
   options.setExperimentalOption("useAutomationExtension", false);
   WebDriver driver = new ChromeDriver(options);
   driver.get(url);
   

Using the above steps I was able to resolve the issue.

Thanks for your answers.

• packed means it will use the smallest possible space for struct Ball - i.e. it will cram fields together without padding
• aligned means each struct Ball will begin on a 4 byte boundary - i.e. for any struct Ball, its address can be divided by 4

SELECT t1.username, t1.date, value
FROM MyTable as t1
INNER JOIN (SELECT username, MAX(date)
            FROM MyTable
            GROUP BY username) as t2 ON  t2.username = t1.username AND t2.date = t1.date

You want the :checkbox:checked selector and map to create an array of the values:

var checkedValues = $('input:checkbox:checked').map(function() {
    return this.value;
}).get();

If your checkboxes have a shared class it would be faster to use that instead, eg. $('.mycheckboxes:checked'), or for a common name $('input[name="Foo"]:checked')

- Update -

If you don't need IE support then you can now make the map() call more succinct by using an arrow function:

var checkedValues = $('input:checkbox:checked').map((i, el) => el.value).get();

I'm a bit new to Bibtex (and to Latex in general) and I'd like to revive this old post since I found it came up in many of my Google search inquiries about the ordering of a bibliography in Latex.

I'm providing a more verbose answer to this question in the hope that it might help some novices out there facing the same difficulties as me.

Here is an example of the main .tex file in which the bibliography is called:

\documentclass{article}
\begin{document}

So basically this is where the body of your document goes.

``FreeBSD is easy to install,'' said no one ever \cite{drugtrafficker88}.

``Yeah well at least I've got chicken,'' said Leeroy Jenkins \cite{goodenough04}.

\newpage
\bibliographystyle{ieeetr} % Use ieeetr to list refs in the order they're cited
\bibliography{references} % Or whatever your .bib file is called
\end{document}

...and an example of the .bib file itself:

@ARTICLE{ goodenough04,
AUTHOR    = "G. D. Goodenough and others", 
TITLE     = "What it's like to have a sick-nasty last name",
JOURNAL   = "IEEE Trans. Geosci. Rem. Sens.",
YEAR      = "xxxx",
volume    = "xx",
number    = "xx",
pages     = "xx--xx"
}
@BOOK{ drugtrafficker88,
AUTHOR    = "G. Drugtrafficker", 
TITLE     = "What it's Like to Have a Misleading Last Name",
YEAR      = "xxxx",
PUBLISHER = "Harcourt Brace Jovanovich, Inc."
ADDRESS   = "The Florida Alps, FL, USA"
}

Note the references in the .bib file are listed in reverse order but the references are listed in the order they are cited in the paper.

More information on the formatting of your .bib file can be found here: http://en.wikibooks.org/wiki/LaTeX/Bibliography_Management

With ggplot2:

p<-qplot(spray,count,data=InsectSprays,geom='boxplot')
p<-p+stat_summary(fun.y=mean,shape=1,col='red',geom='point')
print(p)

I think the easiest way to think about this variable like input parameter in lambda expression in C#. I.e. $_ is similar to x in x => Console.WriteLine(x) anonymous function in C#. Consider following examples:

PowerShell:

1,2,3 | ForEach-Object {Write-Host $_}

Prints:

1
2
3

or

1,2,3 | Where-Object {$_ -gt 1}

Prints:

2
3

And compare this with C# syntax using LINQ:

var list = new List<int> { 1, 2, 3 };
list.ForEach( _ => Console.WriteLine( _ ));

Prints:

1
2
3

or

list.Where( _ => _ > 1)
    .ToList()
    .ForEach(s => Console.WriteLine(s));

Prints:

2
3

Using the indexOf function was not cutting it on my collection of REST resources.

I had to create a function that retrieves the array index of a resource sitting in a collection of resources:

factory.getResourceIndex = function(resources, resource) {
  var index = -1;
  for (var i = 0; i < resources.length; i++) {
    if (resources[i].id == resource.id) {
      index = i;
    }
  }
  return index;
}

$scope.unassignedTeams.splice(CommonService.getResourceIndex($scope.unassignedTeams, data), 1);

Just a side note, in Python 2.0 you could compare anything to anything (int to string). As this wasn't explicit, it was changed in 3.0, which is a good thing as you are not running into the trouble of comparing senseless values with each other or when you forget to convert a type.
