Since the purpose of these COMPILER directives are to tell the compiler NOT to include code, debug code,beta code, or perhaps code that is needed by all of your end users, except say those the advertising department, i.e. #Define AdDept you want to be able include or remove them based on your needs. Without having to change your source code if for example a non AdDept merges into the AdDept. Then all that needs to be done is to include the #AdDept directive in the compiler options properties page of an existing version of the program and do a compile and wa la! the merged program's code springs alive!.

You might also want to use a declarative for a new process that is not ready for prime time or that can not be active in the code until it's time to release it.

Anyhow, that's the way I do it.

Another useful Find short key sequence is Ctrl (+ Shift) F --> ALT C --> ALT W for switching between exact and fuzzy searches.

public static String getExten(String path) {
    int i = path.lastIndexOf('.');
    if (i > 0) {
       return path.substring(i);
    }
    else return "";
}
public static List<String> GetAllFiles(String path, List<String>fileList){
    File file = new File(path);
    
    File[] files = file.listFiles();
    for(File folder:files) {
        if(extensions.contains(getExten(folder.getPath()))) {
            fileList.add(folder.getPath());
        }
    }
    File[] direcs = file.listFiles(File::isDirectory);
    for(File dir:direcs) {
        GetAllFiles(dir.getPath(),fileList);
    }
    return fileList;
    
}

This is a simple recursive function that should give you all the files. extensions is a list of string that contains only those extensions which are accepted. Example extensions = [".txt",".docx"] etc.

If you want to reset it, then simple use:

<input type="reset" value="Reset" />

But beware, it will not clear out textboxes that have default value. For example, if we have the following textboxes and by default, they have the following values:

<input id="textfield1" type="text" value="sample value 1" />
<input id="textfield2" type="text" value="sample value 2" />

So, to clear it out, compliment it with javascript:

function clearText()  
{
    document.getElementById('textfield1').value = "";
    document.getElementById('textfield2').value = "";
}  

And attach it to onclick of the reset button:
<input type="reset" value="Reset" onclick="clearText()" />

bash has a builtin

pushd SOME_PATH
run_stuff
...
...
popd 

\includegraphics<1>{A}%
\includegraphics<2>{B}%
\includegraphics<3>{C}%

The % is important. This will keep all the images fixed.

I had the same issue, and this is how I fixed it.

Install Ruby-sass using below command
sudo apt-get -y update
sudo apt-get -y install ruby-full
sudo apt install ruby-sass
gem install bundler

Example
sass SCSS_FILE_PATH:CSS_FILE_PATH;

e.g sass mda/at-md-black.scss:css/at-md-black.css;

Here is a good breakdown of the pros and cons:

So, it appears that constants should be used when it is very unlikely that the value will ever change, or if no external apps/libs will be using the constant. Static readonly fields should be used when run-time calculation is required, or if external consumers are a factor.

After some time with Google I asked on the ask ubuntu chat room.

A user there was king enough to help me find the solution I was looking for and i wanted to share so that any following suers running into this may find it:

grep -P "(^|\s)abc(\s|$)" gives the result I was looking for. -P is an experimental implementation of perl regexps.

grepping for abc and then using filters like grep -v '@abc' (this is far from perfect...) should also work, but my patch does something similar.

To get employee names starting with A or B listed in order...

select employee_name 
from employees
where employee_name LIKE 'A%' OR employee_name LIKE 'B%'
order by employee_name

If you are using Microsoft SQL Server you could use

....
where employee_name  LIKE '[A-B]%'
order by employee_name

This is not standard SQL though it just gets translated to the following which is.

WHERE  employee_name >= 'A'
       AND employee_name < 'C' 

For all variants you would need to consider whether you want to include accented variants such as Á and test whether the queries above do what you want with these on your RDBMS and collation options.

you can always have http link to your git project. You can use that instead of ssh link. This is just an option you have

As I want to handle both IPv4 and IPv6, I am using VARBINARY(16) and the following SQL CLR functions to convert the text IP address presentation to bytes and the reverse:

[SqlFunction(DataAccess = DataAccessKind.None, IsDeterministic = true)]
public static SqlBytes GetIPAddressBytesFromString (SqlString value)
{
    IPAddress IP;

    if (IPAddress.TryParse(value.Value, out IP))
    {
        return new SqlBytes(IP.GetAddressBytes());
    }
    else
    {
        return new SqlBytes();
    }
}


[SqlFunction(DataAccess = DataAccessKind.None, IsDeterministic = true)]
public static SqlString GetIPAddressStringFromBytes(SqlBytes value)
{
    string output;

    if (value.IsNull)
    {
        output = "";
    }
    else
    {
        IPAddress IP = new IPAddress(value.Value);
        output = IP.ToString();
    }

    return new SqlString(output);
}

Geocoding through Javascript:

I had to use Debug.print instead of Print, which works in the Immediate window.

Make sure your .NET version 4.5 or greater

Quick summary, you can do either:

1. Include the JavaFX modules via --module-path and --add-modules like in José's answer.

   OR

2. Once you have JavaFX libraries added to your project (either manually or via maven/gradle import), add the module-info.java file similar to the one specified in this answer. (Note that this solution makes your app modular, so if you use other libraries, you will also need to add statements to require their modules inside the module-info.java file).

This answer is a supplement to Jose's answer.

The situation is this:

1. You are using a recent Java version, e.g. 13.
2. You have a JavaFX application as a Maven project.
3. In your Maven project you have the JavaFX plugin configured and JavaFX dependencies setup as per Jose's answer.
4. You go to the source code of your main class which extends Application, you right-click on it and try to run it.
5. You get an IllegalAccessError involving an "unnamed module" when trying to launch the app.

Excerpt for a stack trace generating an IllegalAccessError when trying to run a JavaFX app from Intellij Idea:

Exception running application org.jewelsea.demo.javafx.springboot.Main

OK, now you are kind of stuck and have no clue what is going on.

What has actually happened is this:

1. Maven has successfully downloaded the JavaFX dependencies for your application, so you don't need to separately download the dependencies or install a JavaFX SDK or module distribution or anything like that.
2. Idea has successfully imported the modules as dependencies to your project, so everything compiles OK and all of the code completion and everything works fine.

So it seems everything should be OK. BUT, when you run your application, the code in the JavaFX modules is failing when trying to use reflection to instantiate instances of your application class (when you invoke launch) and your FXML controller classes (when you load FXML). Without some help, this use of reflection can fail in some cases, generating the obscure IllegalAccessError. This is due to a Java module system security feature which does not allow code from other modules to use reflection on your classes unless you explicitly allow it (and the JavaFX application launcher and FXMLLoader both require reflection in their current implementation in order for them to function correctly).

This is where some of the other answers to this question, which reference module-info.java, come into the picture.

So let's take a crash course in Java modules:

• https://www.baeldung.com/java-9-modularity

The key part is this:

4.9. Opens

If we need to allow reflection of private types, but we don't want all of our code exposed, we can use the opens directive to expose specific packages.

But remember, this will open the package up to the entire world, so make sure that is what you want:

module my.module { opens com.my.package; }

So, perhaps you don't want to open your package to the entire world, then you can do:

4.10. Opens … To

Okay, so reflection is great sometimes, but we still want as much security as we can get from encapsulation. We can selectively open our packages to a pre-approved list of modules, in this case, using the opens…to directive:

module my.module { opens com.my.package to moduleOne, moduleTwo, etc.; }

So, you end up creating a src/main/java/module-info.java class which looks like this:

module org.jewelsea.demo.javafx.springboot {
    requires javafx.fxml;
    requires javafx.controls;
    requires javafx.graphics;
    opens org.jewelsea.demo.javafx.springboot to javafx.graphics,javafx.fxml;
}

Where, org.jewelsea.demo.javafx.springboot is the name of the package which contains the JavaFX Application class and JavaFX Controller classes (replace this with the appropriate package name for your application). This tells the Java runtime that it is OK for classes in the javafx.graphics and javafx.fxml to invoke reflection on the classes in your org.jewelsea.demo.javafx.springboot package. Once this is done, and the application is compiled and re-run things will work fine and the IllegalAccessError generated by JavaFX's use of reflection will no longer occur.

But what if you don't want to create a module-info.java file

If instead of using the the Run button in the top toolbar of IDE to run your application class directly, you instead:

1. Went to the Maven window in the side of the IDE.
2. Chose the javafx maven plugin target javafx.run.
3. Right-clicked on that and chose either Run Maven Build or Debug....

Then the app will run without the module-info.java file. I guess this is because the maven plugin is smart enough to dynamically include some kind of settings which allows the app to be reflected on by the JavaFX classes even without a module-info.java file, though I don't know how this is accomplished.

To get that setting transferred to the Run button in the top toolbar, right-click on the javafx.run Maven target and choose the option to Create Run/Debug Configuration for the target. Then you can just choose Run from the top toolbar to execute the Maven target.

Bower maintains a single version of modules, it only tries to help you select the correct/best one for you.

Javascript dependency management : npm vs bower vs volo?

NPM is better for node modules because there is a module system and you're working locally. Bower is good for the browser because currently there is only the global scope, and you want to be very selective about the version you work with.

From the docs:

String.trim();

This page gives a decent breakdown of the different join types, as well as venn diagram visualizations to help... well... visualize the difference in the joins.

As the comments said this is a quite basic query from the sounds of it, so you should try to understand the differences between the joins and what they actually mean.

Check out http://blog.codinghorror.com/a-visual-explanation-of-sql-joins/

You're looking for a query such as:

DECLARE @table1 TABLE (test int)
DECLARE @table2 TABLE (test int)

INSERT INTO @table1
(
    test
)
SELECT 1
UNION ALL SELECT 2

INSERT INTO @table2
(
    test
)
SELECT 1
UNION ALL SELECT 3

-- Here's the important part
SELECT  a.*
FROM    @table1 a
LEFT    join @table2 b on a.test = b.test -- this will return all rows from a
WHERE   b.test IS null -- this then excludes that which exist in both a and b

-- Returned results:

2

You could go into the designer of the web form and change the "webcontrols" to be "public" instead of "protected" but I'm not sure how safe that is. I prefer to make hidden inputs and have some jQuery set the values into those hidden inputs, then create public properties in the web form's class (code behind), and access the values that way.

Another "Up Tick" for AR..., but if you don't have to use interop I would avoid it altogether. This product is actually quite interesting: http://www.clearoffice.com/ and it provides a very intuitive, fully managed, api for manipulation excel files and seems to be free. (at least for the time being) SpreadSheetGear is also excellent but pricey.

my two cents.

If you are on Windows, here is a PowerShell script that will print the 10 largest files in your repository:

$revision_objects = git rev-list --objects --all;
$files = $revision_objects.Split() | Where-Object {$_.Length -gt 0 -and $(Test-Path -Path $_ -PathType Leaf) };
$files | Get-Item -Force | select fullname, length | sort -Descending -Property Length | select -First 10

$request->validate([
    'phone' => 'numeric|required',
    'body' => 'required',
]);

At first I was as reluctant as @fmark to switch from optparse to argparse, because:

1. I thought the difference was not that huge.
2. Quite some VPS still provides Python 2.6 by default.

Then I saw this doc, argparse outperforms optparse, especially when talking about generating meaningful help message: http://argparse.googlecode.com/svn/trunk/doc/argparse-vs-optparse.html

And then I saw "argparse vs. optparse" by @Nicholas, saying we can have argparse available in python <2.7 (Yep, I didn't know that before.)

Now my two concerns are well addressed. I wrote this hoping it will help others with a similar mindset.

Try this :

html_source_code = requests.get("http://www.example.com/",
                   headers={'User-Agent':'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/44.0.2403.107 Safari/537.36',
                            'Upgrade-Insecure-Requests': '1',
                            'x-runtime': '148ms'}, 
                   allow_redirects=True).content

Give attention to CHARSET and COLLATE parameters when you create a table. In terms of FOREIGN KEY problems something like that:

CREATE TABLE yourTableName (
....
....
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;

In my case i couldn´t create the table with FOREIGN KEY references. First i got the Error Code 1005 which pretty much says nothing. Then i added COLLATE and finally the error message complaining about CHARSET.

Error Code: 1253. COLLATION 'utf8_unicode_ci' is not valid for CHARACTER SET 'latin1'

After that correction my issue was solved.

Semantically there is no difference between these cases in LDAP.

If you have both date and time information in the numeric value, then use as.POSIXct. Data.table package IDateTime format is such a case. If you use fwrite to save a file, the package automatically converts date-times to idatetime format which is unix time. To convert back to normal format following can be done.

Example: Let's say you have a unix time stamp with date and time info: 1442866615

> as.POSIXct(1442866615,origin="1970-01-01")
[1] "2015-09-21 16:16:54 EDT"

Not sure it stands for anything special. It's just a convention that you supply an 'all' rule, and generally it's used to list all the sub-targets needed to build the entire project, hence the name 'all'. The only thing special about it is that often times people will put it in as the first target in the makefile, which means that just typing 'make' alone will do the same thing as 'make all'.

This is how I solved the issue, I added this open function of the dialog:

  open: function () {
                $('.ui-dialog').css("top","0px");                                
                    }

This now opens the dialog at the top of the screen, no matter where the page is scrolled to and in all browsers.

Run composer self-update and composer clearcache remove vendor and composer.lock restart your local environment and then run php -d memory_limit=-1 /usr/local/bin/composer install

This should also work:

AggregateValues("hello", MyList.ConvertAll(c => c.Name).ToArray())

Content that is floating does not influence the height of its container. The element contains no content that isn't floating (so nothing stops the height of the container being 0, as if it were empty).

Setting overflow: hidden on the container will avoid that by establishing a new block formatting context. See methods for containing floats for other techniques and containing floats for an explanation about why CSS was designed this way.

You can simply place a forward declaration of your second() function in your main.cpp above main(). If your second.cpp has more than one function and you want all of it in main(), put all the forward declarations of your functions in second.cpp into a header file and #include it in main.cpp.

Like this-

Second.h:

void second();
int third();
double fourth();

main.cpp:

#include <iostream>
#include "second.h"
int main()
{
    //.....
    return 0;
}

second.cpp:

void second()
{
    //...
}

int third()
{ 
    //...
    return foo;
}

double fourth()
{ 
    //...
    return f;
}

Note that: it is not necessary to #include "second.h" in second.cpp. All your compiler need is forward declarations and your linker will do the job of searching the definitions of those declarations in the other files.

This kind of thing doesn't just magically happen on its own; you changed something! In industry we use version control to make regular savepoints, so when something goes wrong we can trace back the specific changes we made that resulted in that problem.

Since you haven't done that here, we can only really guess. In Visual Studio, Intellisense (the technology that gives you auto-complete dropdowns and those squiggly red lines) works separately from the actual C++ compiler under the bonnet, and sometimes gets things a bit wrong.

In this case I'd ask why you're including both cstdlib and stdlib.h; you should only use one of them, and I recommend the former. They are basically the same header, a C header, but cstdlib puts them in the namespace std in order to "C++-ise" them. In theory, including both wouldn't conflict but, well, this is Microsoft we're talking about. Their C++ toolchain sometimes leaves something to be desired. Any time the Intellisense disagrees with the compiler has to be considered a bug, whichever way you look at it!

Anyway, your use of using namespace std (which I would recommend against, in future) means that std::system from cstdlib now conflicts with system from stdlib.h. I can't explain what's going on with std::cout and std::cin.

Try removing #include <stdlib.h> and see what happens.

If your program is building successfully then you don't need to worry too much about this, but I can imagine the false positives being annoying when you're working in your IDE.

Here I would like to share my working code :

<input type="text" name="someData" ng-model="data" ng-init="data=2" style="display: none;"/>_x000D_
OR_x000D_
<input type="hidden" name="someData" ng-model="data" ng-init="data=2"/>_x000D_
OR_x000D_
<input type="hidden" name="someData" ng-init="data=2"/>

Use .keyup instead of keypress.

Also use $(this).val() or just this.value to access the current input value.

DEMO here

Info about .keypress from jQuery docs,

The keypress event is sent to an element when the browser registers keyboard input. This is similar to the keydown event, except in the case of key repeats. If the user presses and holds a key, a keydown event is triggered once, but separate keypress events are triggered for each inserted character. In addition, modifier keys (such as Shift) trigger keydown events but not keypress events.

Since PostgreSQL 9.1 there is the convenient FOREACH:

DO
$do$
DECLARE
   m   varchar[];
   arr varchar[] := array[['key1','val1'],['key2','val2']];
BEGIN
   FOREACH m SLICE 1 IN ARRAY arr
   LOOP
      RAISE NOTICE 'another_func(%,%)',m[1], m[2];
   END LOOP;
END
$do$

Solution for older versions:

DO
$do$
DECLARE
   arr varchar[] := '{{key1,val1},{key2,val2}}';
BEGIN
   FOR i IN array_lower(arr, 1) .. array_upper(arr, 1)
   LOOP
      RAISE NOTICE 'another_func(%,%)',arr[i][1], arr[i][2];
   END LOOP;
END
$do$

Also, there is no difference between varchar[] and varchar[][] for the PostgreSQL type system. I explain in more detail here.

The DO statement requires at least PostgreSQL 9.0, and LANGUAGE plpgsql is the default (so you can omit the declaration).

You could explicitly set the display property to "block" so it behaves like a block level element, but in that case you should probably just use a div instead.

<span style="display:block; background-color:red; width:100px;"></span>

The validate plugin will only validate the current/focused element.Therefore you will need to add a custom rule to the validator to validate all the checkboxes. Similar to the answer above.

$.validator.addMethod("roles", function(value, elem, param) {
   return $(".roles:checkbox:checked").length > 0;
},"You must select at least one!");

And on the element:

<input class='{roles: true}' name='roles' type='checkbox' value='1' />

In addition, you will likely find the error message display, not quite sufficient. Only 1 checkbox is highlighted and only 1 message displayed. If you click another separate checkbox, which then returns a valid for the second checkbox, the original one is still marked as invalid, and the error message is still displayed, despite the form being valid. I have always resorted to just displaying and hiding the errors myself in this case.The validator then only takes care of not submitting the form.

The other option you have is to write a function that will change the value of a hidden input to be "valid" on the click of a checkbox and then attach the validation rule to the hidden element. This will only validate in the onSubmit event though, but will display and hide messages at the appropriate times. Those are about the only options that you can use with the validate plugin.

Hope that helps!

DEMO

var DepartmentFactory = function(data) {
    this.id = data.Id;
    this.name = data.DepartmentName;
    this.active = data.Active;
}

var objArray = [];
objArray.push(new DepartmentFactory({Id: 1, DepartmentName: 'Marketing', Active: true}));
objArray.push(new DepartmentFactory({Id: 2, DepartmentName: 'Sales', Active: true}));
objArray.push(new DepartmentFactory({Id: 3, DepartmentName: 'Development', Active: true}));
objArray.push(new DepartmentFactory({Id: 4, DepartmentName: 'Accounting', Active: true}));

console.log(objArray.sort(function(a, b) { return a.name > b.name}));

You need to set certificate to hit this url. use below code to set keystore:

System.setProperty("javax.net.ssl.trustStore","clientTrustStore.key");

System.setProperty("javax.net.ssl.trustStorePassword","qwerty");

If you are concerned about the string looking nice you could do this:

    [Range(0, Double.PositiveInfinity)]

This will have a default error message of:

The field SuchAndSuch must be between 0 and Infinity.

You can create a util method that converts any collection to a java list

public static List<?> convertObjectToList(Object obj) {
    List<?> list = new ArrayList<>();
    if (obj.getClass().isArray()) {
        list = Arrays.asList((Object[])obj);
    } else if (obj instanceof Collection) {
        list = new ArrayList<>((Collection<?>)obj);
    }
    return list;
}

you can also mix with this validation below:

public static boolean isCollection(Object obj) {
  return obj.getClass().isArray() || obj instanceof Collection;
}

In Mysql, you can not update one table by subquery the same table.

You can separate the query in two parts, or do

 UPDATE TABLE_A AS A
 INNER JOIN TABLE_A AS B ON A.field1 = B.field1
 SET field2 = ? 

I just spent the last few hours on this same issue... Just go here "http://www.ftdichip.com/Drivers/VCP.htm", download the latest drivers and reboot. Should work just fine after that. I also downloaded a nightly of the Arduino software, but I don't hunk that made a difference.

The code you have posted here and code on your site both are different. There is a break <br> after second image, so the third image into new line, remove this <br> and it will display correctly.

This is what I'm teaching my students tomorrow. After years of looking at this stuff... ie all of the documentation above http://www.cpearson.com/excel/errorhandling.htm comes to mind as an excellent one...

I hope this summarizes it for others. There is an Err object and an active (or inactive) ErrorHandler. Both need to be handled and reset for new errors.

Paste this into a workbook and step through it with F8.

Sub ErrorHandlingDemonstration()

    On Error GoTo ErrorHandler

    'this will error
    Debug.Print (1 / 0)

    'this will also error
    dummy = Application.WorksheetFunction.VLookup("not gonna find me", Range("A1:B2"), 2, True)

    'silly error
    Dummy2 = "string" * 50

    Exit Sub

zeroDivisionErrorBlock:
    maybeWe = "did some cleanup on variables that shouldnt have been divided!"
    ' moves the code execution to the line AFTER the one that errored
    Resume Next

vlookupFailedErrorBlock:
    maybeThisTime = "we made sure the value we were looking for was in the range!"
    ' moves the code execution to the line AFTER the one that errored
    Resume Next

catchAllUnhandledErrors:
    MsgBox(thisErrorsDescription)
    Exit Sub

ErrorHandler:
    thisErrorsNumberBeforeReset = Err.Number
    thisErrorsDescription = Err.Description
    'this will reset the error object and error handling
    On Error GoTo 0
    'this will tell vba where to go for new errors, ie the new ErrorHandler that was previous just reset!
    On Error GoTo ErrorHandler

    ' 11 is the err.number for division by 0
    If thisErrorsNumberBeforeReset = 11 Then
        GoTo zeroDivisionErrorBlock
    ' 1004 is the err.number for vlookup failing
    ElseIf thisErrorsNumberBeforeReset = 1004 Then
        GoTo vlookupFailedErrorBlock
    Else
        GoTo catchAllUnhandledErrors
    End If

End Sub

This will work for null able dateTime parameter

. .

SearchUsingDate(DateTime? StartDate, DateTime? EndDate){
     DateTime LastDate;
     if (EndDate != null)
       {
          LastDate = (DateTime)EndDate;
          LastDate = LastDate.AddDays(1);
          EndDate = LastDate;
        }
}

Tried multiple of these, I switched to Cygwin instead which fixed python and some other problems I was having on Windows:

Like this:

$dd = document.getElementById("yourselectelementid");
$so = $dd.options[$dd.selectedIndex];

The easiest way for Spring Boot 2 without dependencies or code changes is just:

spring:
  autoconfigure:
    exclude: org.springframework.boot.autoconfigure.security.servlet.SecurityAutoConfiguration

Using PyParsing

import pyparsing as pp

word = pp.Word(pp.alphanums)

s = 'gfgfdAAA1234ZZZuijjk'
rule = pp.nestedExpr('AAA', 'ZZZ')
for match in rule.searchString(s):
    print(match)

which yields:

[['1234']]

Ran in to this problem a while ago. Website couldn't access video file on local PC due to security settings (understandable really) ONLY way I could get around it was to run a webserver on the local PC (server2Go) and all references to the video file from the web were to the localhost/video.mp4

<div id="videoDiv">
     <video id="video" src="http://127.0.0.1:4001/videos/<?php $videoFileName?>" width="70%" controls>
    </div>
<!--End videoDiv-->

Not an ideal solution but worked for me.

One way to handle this is to put the information as an attribute on the primary one. I must stress, I really think this is the appropriate thing to do only when the two pieces of information are related such that one has information about the other.

For example, I sometimes stash the name of "crucial variables" or variables that have been significantly modified by storing a list of variable names as an attribute on the data frame:

attr(my.DF, 'Modified.Variables') <- DVs.For.Analysis$Names.of.Modified.Vars
return(my.DF)

This allows me to store a list of variable names with the data frame itself.

The simplest way to get the current date in current locale (device locale!) :

String currentDate = DateFormat.getDateInstance().format(Calendar.getInstance().getTime());

If you want to have the date in different styles use getDateInstance(int style):

DateFormat.getDateInstance(DateFormat.FULL).format(Calendar.getInstance().getTime());

Other styles: DateFormat.LONG, DateFormat.DATE_FIELD, DateFormat.DAY_OF_YEAR_FIELD, etc. (use CTRL+Space to see all of them)

If you need the time too:

String currentDateTime = DateFormat.getDateTimeInstance(DateFormat.DEFAULT,DateFormat.LONG).format(Calendar.getInstance().getTime());

You have to change the file from .html to .php.

and add this following line

header('Content-Type: text/html; charset=utf-8');

A new answer that uses dplyr and tidyr:

Extracts the desired column names and converts to a list

library(tidyverse)

col_names <- raw_dta %>% 
  slice(2) %>%
  pivot_longer(
    cols = "X2":"X10", # until last named column
    names_to = "old_names",
    values_to = "new_names") %>% 
  pull(new_names)

Removes the incorrect rows and adds the correct column names

dta <- raw_dta %>% 
  slice(-1, -2) %>% # Removes the rows containing new and original names
  set_names(., nm = col_names)

>>> a = datetime.timedelta(seconds=65)
datetime.timedelta(0, 65)
>>> str(a)
'0:01:05'

df = pd.DataFrame(['-',3,2,5,1,-5,-1,'-',9])
df = df.where(df!='-', None)

In Internet Explorer, parentElement is undefined for SVG elements, whereas parentNode is defined.

Use a credential store.

For Git 2.11+ on OS X and Linux, use Git's built in credential store:

git config --global credential.helper libsecret

For msysgit 1.7.9+ on Windows:

git config --global credential.helper wincred

For Git 1.7.9+ on OS X use:

git config --global credential.helper osxkeychain

To mark as obsolete with a warning:

[Obsolete]
private static void SomeMethod()

You get a warning when you use it:

And with IntelliSense:

If you want a message:

[Obsolete("My message")]
private static void SomeMethod()

Here's the IntelliSense tool tip:

Finally if you want the usage to be flagged as an error:

[Obsolete("My message", true)]
private static void SomeMethod()

When used this is what you get:

Note: Use the message to tell people what they should use instead, not why it is obsolete.

In Symfony 4.3.1 I use this:

services.yaml

HTTP_USERNAME: 'admin'
HTTP_PASSWORD: 'password123'

FrontController.php

$username = $this->container->getParameter('HTTP_USERNAME');
$password = $this->container->getParameter('HTTP_PASSWORD');

I found it!

Simply print out $Error[0] for the last error message.

The following will do.

string datestring = DateTime.Now.ToString("yyyy-MM-dd", CultureInfo.InvariantCulture);

Your methods don't refer to an object (that is, self), so you should use the @staticmethod decorator:

class MathsOperations:
    @staticmethod
    def testAddition (x, y):
        return x + y

    @staticmethod
    def testMultiplication (a, b):
        return a * b

Generally speaking you should not call GC explicitly with System.gc(). There is even the IO lecture (http://www.youtube.com/watch?v=_CruQY55HOk) where they explain what the GC pauses log mean and in which they also state to never call System.gc() because Dalvik knows better than you when to do so.

On the other hand as mentioned in above answers already GC process in Android (like everything else) is sometimes buggy. This means Dalvik GC algorithms are not on par with Hotspot or JRockit JVMs and might get things wrong on some occasions. One of those occasions is when allocating bitmap objects. This is a tricky one because it uses Heap and Non Heap memory and because one loose instance of bitmap object on memory constrained device is enough to give you an OutOfMemory exception. So calling it after you don't need this bitmap any-more is generally suggested by many developers and is even considered good practice by some people.

Better practice is using .recycle() on a bitmap as it is what this method is made for, as it marks native memory of the bitmap as safe to delete. Keep in mind that this is very version dependent, meaning it will generally be required on older Android versions (Pre 3.0 I think) but will not be required on later ones. Also it won't hurt much using it on newer versions ether (just don't do this in a loop or something like that). New ART runtime changed a lot here because they introduced special Heap "partition" for big objects but I think it will not hurt much to do this with ART ether.

Also one very important note about System.gc(). This method is not a command that Dalvik (or JVMs) are obligated to respond to. Consider it more like saying to Virtual machine "Could you please do garbage collection if it's not a hassle".

Update October 2019

The following should work "stand-alone" on all modern browsers without any dependencies or transpilation.

<!-- display a pop-up with the selected values from the <select> element -->

<script>
 const showSelectedOptions = options => alert(
   [...options].filter(o => o.selected).map(o => o.value)
 )
</script>

<select multiple onchange="showSelectedOptions(this.options)">
  <option value='1'>one</option>
  <option value='2'>two</option>
  <option value='3'>three</option>
  <option value='4'>four</option>
</select>

There is no i in xpath is not entirely true. You can still use the count() to find the index.

The page has 2 tables and has 6 columns each with unique column names and 6 rows with variable data. The last row has the Modify button in both the tables.

Assuming that the user has to select the 4th Modify button from the first table based on the heading

Use the xpath //th[.='Heading 4']/ancestor::thead/following-sibling::tbody/tr/td[count(//tr/th[.='Heading 4']/preceding-sibling::th)+1]/button

The count() operator comes in handy in situations like these.

Logic:

1. Find the header for the Modify button using //th[.='Heading 4']
2. Find the index of the header column using count(//tr/th[.='Heading 4']/preceding-sibling::th)+1

Note: Index starts at 0

3. Get the rows for the corresponding header using //th[.='Heading 4']/ancestor::thead/following-sibling::tbody/tr/td[count(//tr/th[.='Heading 4']/preceding-sibling::th)+1]

4. Get the Modify button from the extracted node list using //th[.='Heading 4']/ancestor::thead/following-sibling::tbody/tr/td[count(//tr/th[.='Heading 4']/preceding-sibling::th)+1]/button

replace the query inside your model function with this

$query = $this->db->query("SELECT id FROM home");

in view:

echo $query->num_rows();

.inspect is what you're looking for, it's way easier IMO than .to_yaml!

user = User.new
user.name = "will"
user.email = "[email protected]"

user.inspect
#<name: "will", email: "[email protected]">

I would suggest taking a look JetBrains AppCode IDE. It has a Reformat Code command. I have come from a C# background and used Visual Studio with Jetbrains Resharper plugin, so learning AppCode has been a pleasure because many of the features in Resharper also exist in AppCode!

Theres too many features to list here but could well be worth checking out

• http://www.jetbrains.com/objc/features/index.html
• http://www.jetbrains.com/objc/

$.ajax({

        type:     "GET",
        url: '<?php echo Base_url("user/your function");?>',
        data: {name: mail},
        dataType: "jsonp",
        jsonp: 'callback',
        jsonpCallback: 'chekEmailTaken',
        success: function(msg){
    }
});
return true;

In controller:

public function ajax_checkjp(){
$checkType = $_GET['name'];
echo $_GET['callback']. '(' . json_encode($result) . ');';  
}

I encounter similar situation. I would like to have background of the last .item to be yellow in the elements that look like...

<div class="container">
  <div class="item">item 1</div>
  <div class="item">item 2</div>
  <div class="item">item 3</div>
  ...
  <div class="item">item x</div>
  <div class="other">I'm here for some reasons</div>
</div>

I use nth-last-child(2) to achieve it.

.item:nth-last-child(2) {
  background-color: yellow;
}

It strange to me because nth-last-child of item suppose to be the second of the last item but it works and I got the result as I expect. I found this helpful trick from CSS Trick

stringBuilder.Remove(stringBuilder.Length - 1, 1);

I wanted to share how you can use this to change a attribute of the button, because it took me some time to figure it out...

For example in order to change it's background to yellow:

$("#"+String(this.id)).css("background-color","yellow");

Integrated Security=true; doesn't work in all SQL providers, it throws an exception when used with the OleDb provider.

So basically Integrated Security=SSPI; is preferred since works with both SQLClient & OleDB provider.

Here's the full set of syntaxes according to MSDN - Connection String Syntax (ADO.NET)

You can use PHP, JSP, ASP or any other server side script to connect with mysql database and and return JSON data that you can parse it to in your android app this link how to do it

• Get the width of the screen.
• Then make margin left 25%
• Make margin right 25%

In this way the content of your container will sit in the middle.

Example: suppose that container width = 800px;

<div class='container' width='device-width' id='updatedContent'>
    <p id='myContent'></p>
    <contents></contents>
    <contents></contents>
</div>

if ($("#myContent").parent === $("updatedContent"))
{
    $("#myContent").css({
        'left': '-(device-width/0.25)px';
        'right': '-(device-width/0.225)px';
    });
}

we also have had similar problems (we're behind a corporate proxy). changing to yarn at least on our jenkins builds made a huge difference.

there are some minor differences in the results between "npm install" and "yarn install" - but nothing that hurts us.

a.update(b)

Will add keys and values from b to a, overwriting if there's already a value for a key.

It's shorter version :

function getDirContents($path) {
    $rii = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($path));

    $files = array(); 
    foreach ($rii as $file)
        if (!$file->isDir())
            $files[] = $file->getPathname();

    return $files;
}

var_dump(getDirContents($path));

For me this worked only:

foreach (ComboBoxItem cbi in someComboBox.Items)
{
    if (cbi.Content as String == "sometextIntheComboBox")
    {
        someComboBox.SelectedItem = cbi;
        break;
    }
}

MOD: and if You have your own objects as items set up in the combobox, then substitute the ComboBoxItem with one of them like:

foreach (Debitor d in debitorCombo.Items)
{
    if (d.Name == "Chuck Norris")
    {
        debitorCombo.SelectedItem = d;
        break;
    }
}

Most ASP.NET sites are easy to identify from the .aspx in the URLs. There are also telltale signs in the HTML source, like a hidden form field named __VIEWSTATE or the WebResource.axd JavaScript. HTML elements will often have id attributes starting with something like _ctl0.

Rails sites will usually include stylesheets from /stylesheets and JavaScript files from /javascripts and each URL will usually have a query string containing a timestamp to thwart caching. Form fields will often follow the naming convention of model_name[attribute_name].

In the example code for the book "Instant OpenCV for iOS" I have found a bash script that copies a project from a folder to another.
Doing a little research I've found a blog post from what seems to be the original author of the script: http://mohrt.blogspot.it/2009/01/renaming-xcode-project-from-command.html, where you can download the script. I gave it a try and running it from terminal like this

    sh renameXcodeProject.sh <name-of-existing-folder> <name-of-folder-to-create>   

works fine.
Additional info can be found opening the file with a text editor. Hope that helps

This really Works .. i had verified lot of sites and finally got the answer

This may occurs when the master.mdf or the mastlog.ldf gets corrupt . In order to solve the issue goto the following path

C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL , there you will find a folder ” Template Data ” , copy the master.mdf and mastlog.ldf and replace it in

C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\DATA folder .

Thats it . Now start the MS SQL service and you are done .

For multiple lines

In chrome, you can apply this css if you need to apply ellipsis on multiple lines.

You can also add width in your css to specify element of certain width:

.multi-line-ellipsis {_x000D_
    overflow: hidden;_x000D_
    display: -webkit-box;_x000D_
    -webkit-line-clamp: 3;_x000D_
    -webkit-box-orient: vertical;_x000D_
}

<p class="multi-line-ellipsis">Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

You simply need to make cab a string:

cab = '6176'

As the error message states, you cannot do <int> in <string>:

>>> 1 in '123'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'in <string>' requires string as left operand, not int
>>> 

because integers and strings are two totally different things and Python does not embrace implicit type conversion ("Explicit is better than implicit.").

In fact, Python only allows you to use the in operator with a right operand of type string if the left operand is also of type string:

>>> '1' in '123'  # Works!
True
>>>
>>> [] in '123'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'in <string>' requires string as left operand, not list
>>>
>>> 1.0 in '123'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'in <string>' requires string as left operand, not float
>>>
>>> {} in '123'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'in <string>' requires string as left operand, not dict

Either use COUNT in your MySQL query or do a SELECT * FROM table and do:

$result = mysql_query("SELECT * FROM table");
$rows = mysql_num_rows($result);
echo "There are " . $rows . " rows in my table.";

It is not very nice to use native php resources like $_GET as Laravel gives us easy ways to get the variables. As a matter of standard, whenever possible use the resources of the laravel itself instead of pure PHP.

There is at least two modes to get variables by GET in Laravel ( Laravel 5.x or greater):

Mode 1

Route:

Route::get('computers={id}', 'ComputersController@index');

Request (POSTMAN or client...):

http://localhost/api/computers=500

Controler - You can access the {id} paramter in the Controlller by:

public function index(Request $request, $id){
   return $id;
}

Mode 2

Route:

Route::get('computers', 'ComputersController@index');

Request (POSTMAN or client...):

http://localhost/api/computers?id=500

Controler - You can access the ?id paramter in the Controlller by:

public function index(Request $request){
   return $request->input('id');
}

__func__ is documented in the C++0x standard at section 8.4.1. In this case it's a predefined function local variable of the form:

static const char __func__[] = "function-name ";

where "function name" is implementation specfic. This means that whenever you declare a function, the compiler will add this variable implicitly to your function. The same is true of __FUNCTION__ and __PRETTY_FUNCTION__. Despite their uppercasing, they aren't macros. Although __func__ is an addition to C++0x

g++ -std=c++98 ....

will still compile code using __func__.

__PRETTY_FUNCTION__ and __FUNCTION__ are documented here http://gcc.gnu.org/onlinedocs/gcc-4.5.1/gcc/Function-Names.html#Function-Names. __FUNCTION__ is just another name for __func__. __PRETTY_FUNCTION__ is the same as __func__ in C but in C++ it contains the type signature as well.

If you have skype installed, close it completely.

If you have sql server installed, go to:

Control panel -> Administrative Tools -> Services

And stop SQL Server Reporting Services

Port 80 must be free now. Click on Wamp icon -> Restart All Services

On Ubuntu and Debian systems, there are several steps needed:

1. In server.xml, change the line <Connector connectionTimeout="20000" port="8080" protocol="HTTP/1.1" redirectPort="8443"/> to have port="80".

2. Install the recommended (not required) authbind package, with a command like:

   sudo apt-get install authbind

3. Enable authbind in the server.xml file (in either /etc/tomcat6 or /etc/tomcat7) by uncommenting and setting the line like:

   AUTHBIND=yes

All three steps are needed.

Sometimes what might be causing the issue has nothing to do with the main class. I had to find this out the hard way, it was a referenced library that I moved and it gave me the:

Could not find or load main class xxx Linux

I just delete that reference and added again and it worked fine again.

Rectangle will have to be a template, otherwise it is just one type. It cannot be a non-template whilst its base magically is. (Its base may be a template instantiation, though you seem to want to maintain the base's functionality as a template.)

One solution, is to add support to the csharp language so that "" isn't the only scheme used for strings.

For another string terminator to the C# language - I'm a fan of backtick in ES6.

string test = `He said to me, "Hello World". How are you?`;

But also, the doubling idea in Markdown might be better:

string test = ""He said to me, "Hello World". How are you?"";

The code does not work at the date of this post. This post is a solution where the visitors to this Q&A jump onto this csharplank ticket for C# and upvote it - https://github.com/dotnet/csharplang/discussions/3917

I've written some code that provides "LINQ to HTML" functionality. I thought I would share it here. It is based on Majestic 12. It takes the Majestic-12 results and produces LINQ XML elements. At that point you can use all your LINQ to XML tools against the HTML. As an example:

        IEnumerable<XNode> auctionNodes = Majestic12ToXml.Majestic12ToXml.ConvertNodesToXml(byteArrayOfAuctionHtml);

        foreach (XElement anchorTag in auctionNodes.OfType<XElement>().DescendantsAndSelf("a")) {

            if (anchorTag.Attribute("href") == null)
                continue;

            Console.WriteLine(anchorTag.Attribute("href").Value);
        }

I wanted to use Majestic-12 because I know it has a lot of built-in knowledge with regards to HTML that is found in the wild. What I've found though is that to map the Majestic-12 results to something that LINQ will accept as XML requires additional work. The code I'm including does a lot of this cleansing, but as you use this you will find pages that are rejected. You'll need to fix up the code to address that. When an exception is thrown, check exception.Data["source"] as it is likely set to the HTML tag that caused the exception. Handling the HTML in a nice manner is at times not trivial...

So now that expectations are realistically low, here's the code :)

                Debug.Assert(!m12chunk.bHashMode);  // popular default for Majestic-12 setting

There is no difference between them.

If you don't specify a value for any of the half-dozen properties that background is a shorthand for, then it is set to its default value. none and transparent are the defaults.

One explicitly sets the background-image to none and implicitly sets the background-color to transparent. The other is the other way around.

I have approximately these problem. I need debug AngularJs application from Visual Studio 2013.

By default IIS Express restricted access to local files (like json).

But, first: JSON have JavaScript syntax.

Second: javascript files is allowed.

So:

1. rename JSON to JS (data.json->data.js).

2. correct load command ($http.get('App/data.js').success(function (data) {...

3. load script data.js to page (<script src="App/data.js"></script>)

Next use loaded data an usual manner. It is just workaround, of course.

From the Sonatype doc:

The answer to this question depends on your own perspective. The great majority of Maven users are going to call Maven a “build tool”: a tool used to build deployable artifacts from source code. Build engineers and project managers might refer to Maven as something more comprehensive: a project management tool. What is the difference? A build tool such as Ant is focused solely on preprocessing, compilation, packaging, testing, and distribution. A project management tool such as Maven provides a superset of features found in a build tool. In addition to providing build capabilities, Maven can also run reports, generate a web site, and facilitate communication among members of a working team.

I'd strongly recommend looking at the Sonatype doc and spending some time looking at the available plugins to understand the power of Maven.

Very briefly, it operates at a higher conceptual level than (say) Ant. With Ant, you'd specify the set of files and resources that you want to build, then specify how you want them jarred together, and specify the order that should occur in (clean/compile/jar). With Maven this is all implicit. Maven expects to find your files in particular places, and will work automatically with that. Consequently setting up a project with Maven can be a lot simpler, but you have to play by Maven's rules!

Do this:

function changeHeight() {
document.getElementById('chartdiv').style.height = "200px"
}
<button type="button" onClick="changeHeight();"> Click Me!</button>

Use this cmd to display the packages in your device (for windows users)

adb shell pm list packages

then you can delete completely the package with the following cmd

adb uninstall com.example.myapp

You should use the flex or flex-basis property rather than width. Read more on MDN.

.flexbox .red {
  flex: 0 0 25em;
}

The flex CSS property is a shorthand property specifying the ability of a flex item to alter its dimensions to fill available space. It contains:

flex-grow: 0;     /* do not grow   - initial value: 0 */
flex-shrink: 0;   /* do not shrink - initial value: 1 */
flex-basis: 25em; /* width/height  - initial value: auto */

A simple demo shows how to set the first column to 50px fixed width.

.flexbox {_x000D_
  display: flex;_x000D_
}_x000D_
.red {_x000D_
  background: red;_x000D_
  flex: 0 0 50px;_x000D_
}_x000D_
.green {_x000D_
  background: green;_x000D_
  flex: 1;_x000D_
}_x000D_
.blue {_x000D_
  background: blue;_x000D_
  flex: 1;_x000D_
}

<div class="flexbox">_x000D_
  <div class="red">1</div>_x000D_
  <div class="green">2</div>_x000D_
  <div class="blue">3</div>_x000D_
</div>

I had the same problem

The problem is that with Subversion 1.7 this doesn't work anymore. The good news is there is a better way to do this - and what it appears I should have been doing this all along. All you need is:

svn cleanup

Recent protocols prefer usage of RFC3339 per golang time package documentation.

In general RFC1123Z should be used instead of RFC1123 for servers that insist on that format, and RFC3339 should be preferred for new protocols. RFC822, RFC822Z, RFC1123, and RFC1123Z are useful for formatting; when used with time.Parse they do not accept all the time formats permitted by the RFCs.

cutOffTime, _ := time.Parse(time.RFC3339, "2017-08-30T13:35:00Z")
// POSTDATE is a date time field in DB (datastore)
query := datastore.NewQuery("db").Filter("POSTDATE >=", cutOffTime).

You can show it pressing Alt+6

Or...

NB. Constructor function names should start with a capital letter to distinguish them from ordinary functions, e.g. MyClass instead of myClass.

Either you can call init from your constructor function:

var myObj = new MyClass(2, true);

function MyClass(v1, v2) 
{
    // ...

    // pub methods
    this.init = function() {
        // do some stuff        
    };

    // ...

    this.init(); // <------------ added this
}

Or more simply you could just copy the body of the init function to the end of the constructor function. No need to actually have an init function at all if it's only called once.

wp_trim_words This function trims text to a certain number of words and returns the trimmed text.

Example:-

echo wp_trim_words( get_the_content(), 40, '...' );

You need to do something like this (If you want to call the method on page load):

new Vue({
    // ...
    methods:{
        getUnits: function() {...}
    },
    created: function(){
        this.getUnits()
    }
});

I had this error, and I tried to fix for a while until I found the solution.

I made a private method buildRecyclerView, and I called it twice, first on onCreateView and then after my callback (in which I fetch data from an API). This is my method buildRecyclerView in my Fragment:

private void buildRecyclerView(View v) {
        mRecyclerView = v.findViewById(R.id.recycler_view_loan);
        mLayoutManager = new LinearLayoutManager(getActivity());
        ((LinearLayoutManager) mLayoutManager).setOrientation(LinearLayoutManager.VERTICAL);
        mRecyclerView.setLayoutManager(mLayoutManager);
        mAdapter = new LoanAdapter(mExampleList);
        mRecyclerView.setLayoutManager(mLayoutManager);
        mRecyclerView.setAdapter(mAdapter);
}

Besides, I have to modify the method get-Item-Count in my adapter, because On on-Create-View the list is null and it through an error. So, my get-Item-Count is the following:

@Override
    public int getItemCount() {
        try {
            return mLoanList.size();
        } catch (Exception ex){return 0;}

    }

_animals.OrderByDescending(a => a.<what_is_here_?>);

If animals would be a list of object Animal, you could use a property to order the list.

public class Animal
{
    public int ID {get; set;}
    public string Name {get; set;}
    ...
}

ObservableCollection<Animal> animals = ...
animals = animals.OrderByDescending(a => a.Name);

pthread_exit() will terminate the calling thread and exit from that(but resources used by calling thread is not released to operating system if it is not detached from main thread.)

pthrade_join() will wait or block the calling thread until target thread is not terminated. In simple word it will wait for to exit the target thread.

In your code, if you put sleep(or delay) in PrintHello function before pthread_exit(), then main thread may be exit and terminate full process, Although your PrintHello function is not completed it will terminate. If you use pthrade_join() function in main before calling pthread_exit() from main it will block main thread and wait to complete your calling thread (PrintHello).

I managed to find network.http.connect.timeout for much older versions of Mozilla:

This preference was one of several added to allow low-level tweaking of the HTTP networking code. After a portion of the same code was significantly rewritten in 2001, the preference ceased to have any effect (as noted in all.js as early as September 2001).

Currently, the timeout is determined by the system-level connection establishment timeout. Adding a way to configure this value is considered low-priority.

It would seem that network.http.connect.timeout hasn't done anything for some time.

I also saw references to network.http.request.timeout, so I did a Google search. The results include lots of links to people recommending that others include it in about:config in what appears to be a mistaken belief that it actually does something, since the same search turns up this about:config entries article:

Pref removed (unused). Previously: HTTP-specific network timeout. Default value is 120.

The same page includes additional information about network.http.connect.timeout:

Pref removed (unused). Previously: determines how long to wait for a response until registering a timeout. Default value is 30.

Disclaimer: The information on the MozillaZine Knowledge Base may be incorrect, incomplete or out-of-date.

Add a try/catch block, if the transaction succeeds it will commit the changes, if the transaction fails the transaction is rolled back:

      VALUES ('Tidd130', 130), ('Tidd230', 230)

If you have a class file at build/com/foo/Hello.class, you can check what java version it is compiled at using the command:

javap -v build/com/foo/Hello.class | grep "major"

Example usage:

$ javap -v build/classes/java/main/org/aguibert/liberty/Book.class | grep major
  major version: 57

According to the table in the OP, major version 57 means the class file was compiled to JDK 13 bytecode level

Search based solutions (*, /...) move cursor, which may be unfortunate.

An alternative is to use enhanced mark.vim plugin, then complete your .vimrc to let double-click trigger highlighting (I don't know how a keyboard selection may trigger a command) :

"Use Mark plugin to highlight selected word  
map <2-leftmouse> \m   

It allows multiple highlightings, persistence, etc.

To remove highlighting, either :

• Double click again
• :Mark (switch off until next selection)
• :MarkClear

Another alternative would be JasperReports: JasperReports Library. It uses iText itself and is more than a PDF library you asked for, but if it fits your needs I'd go for it.

Simply put, it allows you to design reports that can be filled during runtime. If you use a custom datasource, you might be able to integrate JasperReports easily into the existing system. It would save you the whole layouting troubles, e.g. when invoices span over more sites where each side should have a footer and so on.

input may have a hidden attribute:

input:checked + span::before {
  content: 'un';
}

<label>
  <input type='checkbox' hidden/>
  <span>check</span>

You can use wget command to download the page and read it into a variable as:

content=$(wget google.com -q -O -)
echo $content

We use the -O option of wget which allows us to specify the name of the file into which wget dumps the page contents. We specify - to get the dump onto standard output and collect that into the variable content. You can add the -q quiet option to turn off's wget output.

You can use the curl command for this aswell as:

content=$(curl -L google.com)
echo $content

We need to use the -L option as the page we are requesting might have moved. In which case we need to get the page from the new location. The -L or --location option helps us with this.

I came across lot of posts searching for the same - "Mongodb Joins" and alternatives or equivalents. So my answer would help many other who are like me. This is the answer I would be looking for.

I am using Mongoose with Express framework. There is a functionality called Population in place of joins.

As mentioned in Mongoose docs.

There are no joins in MongoDB but sometimes we still want references to documents in other collections. This is where population comes in.

This StackOverflow answer shows a simple example on how to use it.

You can use updateMany() methods of mongodb to update multiple document

Simple query is like this

db.collection.updateMany(filter, update, options)

For more doc of uppdateMany read here

As per your requirement the update code will be like this:

User.updateMany({"created": false}, {"$set":{"created": true}});

here you need to use $set because you just want to change created from true to false. For ref. If you want to change entire doc then you don't need to use $set

You can do what Hudson (continuous integration project) does. you download a war which can be deployed in tomcat or to execute using

java -jar hudson.war

(Because it has an embedded Jetty engine, running it from command line cause a server to be launched.) Anyway by looking at hudson's manifest I understand that they put a Main class in the root for the archive. In your case your war layout should be look like:

under root:

• mypackage/MyEntryPointClass.class
• WEB-INF/lib
• WEB-INF/classes
• META-INF/MANIFEST.MF

while the manifest should include the following line:

Main-Class: mypackage.MyEntryPointClass

please notice that the mypackage/MyEntryPointClass.class is accessable from the command line only, and the classes under WEB-INF/classes are accessable from the application server only.

There are some quirks to be aware of here.

1. HTMLIFrameElement.contentWindow is probably the easier way, but it's not quite a standard property and some browsers don't support it, mostly older ones. This is because the DOM Level 1 HTML standard has nothing to say about the window object.

2. You can also try HTMLIFrameElement.contentDocument.defaultView, which a couple of older browsers allow but IE doesn't. Even so, the standard doesn't explicitly say that you get the window object back, for the same reason as (1), but you can pick up a few extra browser versions here if you care.

3. window.frames['name'] returning the window is the oldest and hence most reliable interface. But you then have to use a name="..." attribute to be able to get a frame by name, which is slightly ugly/deprecated/transitional. (id="..." would be better but IE doesn't like that.)

4. window.frames[number] is also very reliable, but knowing the right index is the trick. You can get away with this eg. if you know you only have the one iframe on the page.

5. It is entirely possible the child iframe hasn't loaded yet, or something else went wrong to make it inaccessible. You may find it easier to reverse the flow of communications: that is, have the child iframe notify its window.parent script when it has finished loaded and is ready to be called back. By passing one of its own objects (eg. a callback function) to the parent script, that parent can then communicate directly with the script in the iframe without having to worry about what HTMLIFrameElement it is associated with.

 if (!dUser) return message.channel.send("Can't find user!");
 if (!message.member.hasPermission('ADMINISTRATOR'))
  return message.reply("You can't you that command!");
 let dMessage = args.join(' ').slice(22);
 if (dMessage.length < 1) return message.reply('You must supply a message!');

 dUser.send(`${dUser} A moderator from WP Coding Club sent you: ${dMessage}`);

For Spark 1.5 or later, you can use the functions package:

from pyspark.sql.functions import *
newDf = df.withColumn('address', regexp_replace('address', 'lane', 'ln'))

Quick explanation:

• The function withColumn is called to add (or replace, if the name exists) a column to the data frame.
• The function regexp_replace will generate a new column by replacing all substrings that match the pattern.

To add to Skelly's Bootstrap 3 no-gutter answer above (https://stackoverflow.com/a/21282059/662883)

Add the following to prevent gutters on a row containing only one column (useful when using column-wrapping: http://getbootstrap.com/css/#grid-example-wrapping):

.row.no-gutter [class*='col-']:only-child,
.row.no-gutter [class*='col-']:only-child
{
    padding-right: 0;
    padding-left: 0;
}

TempData is also a dictionary object that stays for the time of an HTTP Request. So, TempData can be used to maintain data between one controller action to the other controller action.

TempData is used to check the null values each time. TempData contain two method keep() and peek() for maintain data state from one controller action to others.

When TempDataDictionary object is read, At the end of request marks as deletion to current read object.

The keep() and peek() method is used to read the data without deletion the current read object.

You can use Peek() when you always want to hold/prevent the value for another request. You can use Keep() when prevent/hold the value depends on additional logic.

Overloading in TempData.Peek() & TempData.Keep() as given below.

TempData.Keep() have 2 overloaded methods.

1. void keep() : That menace all the data not deleted on current request completion.

2. void keep(string key) : persist the specific item in TempData with help of name.

TempData.Peek() no overloaded methods.

1. object peek(string key) : return an object that contain items with specific key without making key for deletion.

Example for return type of TempData.Keep() & TempData.Peek() methods as given below.

public void Keep(string key) { _retainedKeys.Add(key); }

public object Peek(string key) { object value = values; return value; }

Here are two other software packages which can be used for DNS caching on Linux:

• dnsmasq
• bind

After configuring the software for DNS forwarding and caching, you then set the system's DNS resolver to 127.0.0.1 in /etc/resolv.conf.

If your system is using NetworkManager you can either try using the dns=dnsmasq option in /etc/NetworkManager/NetworkManager.conf or you can change your connection settings to Automatic (Address Only) and then use a script in the /etc/NetworkManager/dispatcher.d directory to get the DHCP nameserver, set it as the DNS forwarding server in your DNS cache software and then trigger a configuration reload.

By default is private. Unless they're nested, classes are internal.

The first problem is that when you call append on a jQuery set with more than one element, a clone of the element to append is created for each and thus the attached event observer is lost.

An alternative way to do it would be to create the link for each element:

function handler() { alert('hello'); }
$('.add_to_this').append(function() {
  return $('<a>Click here</a>').click(handler);
})

Another potential problem might be that the event observer is attached before the element has been added to the DOM. I'm not sure if this has anything to say, but I think the behavior might be considered undetermined. A more solid approach would probably be:

function handler() { alert('hello'); }
$('.add_to_this').each(function() {
  var link = $('<a>Click here</a>');
  $(this).append(link);
  link.click(handler);
});

For InstallShield MSI based projects I have found the following to work:

setup.exe /s /x /b"C:\FolderInWhichMSIWillBeExtracted" /v"/qn"

This command will lead to an extracted MSI in a directory you can freely specify and a silently failed uninstall of the product.

The command line basically tells the setup.exe to attempt to uninstall the product (/x) and do so silently (/s). While doing that it should extract the MSI to a specific location (/b).

The /v command passes arguments to Windows Installer, in this case the /qn argument. The /qn argument disables any GUI output of the installer.

Prepared statement is more secure. It will convert a parameter to the specified type.

For example stmt.setString(1, user); will convert the user parameter to a String.

Suppose that the parameter contains a SQL string containing an executable command: using a prepared statement will not allow that.

It adds metacharacter (a.k.a. auto conversion) to that.

This makes it is more safe.

If you are working on .NET 4.5 project in VS 2012 (or newer), you can just Special Paste your XML file as classes.

1. Copy your XML file's content to clipboard
2. In editor, select place where you want your classes to be pasted
3. From the menu, select EDIT > Paste Special > Paste XML As Classes

Probably the only choice is to read it on the client side and transfer it manually to the server (GET/POST/AJAX). Regards Artur

Found solution on the error page itself. Just needed to add requestValidationMode="2.0" in web.config

You can use the strtotime and date functions like this:

echo date('Y', strtotime('2068-06-15'));

Note however that PHP can handle year upto 2038

You can test it out here

If your date is always in that format, you can also get the year like this:

$parts = explode('-', '2068-06-15');
echo $parts[0];

Here's how I solved that problem:

int pHeight =  picture.getHeight();
int pWidth = picture.getWidth();
int vWidth = preview.getWidth();
preview.getLayoutParams().height = (int)(vWidth*((double)pHeight/pWidth));

preview - imageView with width setted to "match_parent" and scaleType to "cropCenter"

picture - Bitmap object to set in imageView src.

That's works pretty well for me.

Try like

$('.printMe').click(function(){
     window.print();
});

or if you want to print selected area try like

$('.printMe').click(function(){
     $("#outprint").print();
});

Often times we are interested in calculating the full significant digits, but for the visual aesthetics, we may want to see only few decimal point when we display the dataframe.

In jupyter-notebook, pandas can utilize the html formatting taking advantage of the method called style.

For the case of just seeing two significant digits of some columns, we can use this code snippet:

Given dataframe

import numpy as np
import pandas as pd

df = pd.DataFrame({'var1': [1.458315, 1.576704, 1.629253, 1.6693310000000001, 1.705139, 1.740447, 1.77598, 1.812037, 1.85313, 1.9439849999999999],
          'var2': [1.500092, 1.6084450000000001, 1.652577, 1.685456, 1.7120959999999998, 1.741961, 1.7708009999999998, 1.7993270000000001, 1.8229819999999999, 1.8684009999999998],
          'var3': [-0.0057090000000000005, -0.005122, -0.0047539999999999995, -0.003525, -0.003134, -0.0012230000000000001, -0.0017230000000000001, -0.002013, -0.001396, 0.005732]})

print(df)
       var1      var2      var3
0  1.458315  1.500092 -0.005709
1  1.576704  1.608445 -0.005122
2  1.629253  1.652577 -0.004754
3  1.669331  1.685456 -0.003525
4  1.705139  1.712096 -0.003134
5  1.740447  1.741961 -0.001223
6  1.775980  1.770801 -0.001723
7  1.812037  1.799327 -0.002013
8  1.853130  1.822982 -0.001396
9  1.943985  1.868401  0.005732

Style to get required format

    df.style.format({'var1': "{:.2f}",'var2': "{:.2f}",'var3': "{:.2%}"})

Gives:

var1    var2    var3
id          
0   1.46    1.50    -0.57%
1   1.58    1.61    -0.51%
2   1.63    1.65    -0.48%
3   1.67    1.69    -0.35%
4   1.71    1.71    -0.31%
5   1.74    1.74    -0.12%
6   1.78    1.77    -0.17%
7   1.81    1.80    -0.20%
8   1.85    1.82    -0.14%
9   1.94    1.87    0.57%

Update

If display command is not found try following:

from IPython.display import display

df_style = df.style.format({'var1': "{:.2f}",'var2': "{:.2f}",'var3': "{:.2%}"})

display(df_style)

Requirements

• To use display command, you need to have installed Ipython in your machine.
• The display command does not work in online python interpreter which do not have IPyton installed such as https://repl.it/languages/python3
• The display command works in jupyter-notebook, jupyter-lab, Google-colab, kaggle-kernels, IBM-watson,Mode-Analytics and many other platforms out of the box, you do not even have to import display from IPython.display

You can sort a map by value as below, more example here

//Sort a Map by their Value.
Map<Integer, String> random = new HashMap<Integer, String>();

random.put(1,"z");
random.put(6,"k");
random.put(5,"a");
random.put(3,"f");
random.put(9,"c");

Map<Integer, String> sortedMap =
        random.entrySet().stream()
                .sorted(Map.Entry.comparingByValue())
                .collect(Collectors.toMap(Map.Entry::getKey, Map.Entry::getValue,
                        (e1, e2) -> e2, LinkedHashMap::new));
System.out.println("Sorted Map: " + Arrays.toString(sortedMap.entrySet().toArray()));

Try this:

sudo mysqld_safe &

Data as factor can be used as input to the plot function.

An answer to a similar question has been given here: https://stat.ethz.ch/pipermail/r-help/2010-December/261873.html

 x=sample(c("Richard", "Minnie", "Albert", "Helen", "Joe", "Kingston"),  
 50, replace=T)
 x=as.factor(x)
 plot(x)

A correct way of iterating over the vector and printing its values is as follows:

#include<vector>

// declare the vector of type int
vector<int> v;

// insert elements in the vector
for (unsigned int i = 0; i < 5; ++i){
    v.push_back(i);
}

// print those elements
for (auto it = v.begin(); it != v.end(); ++it){
    std::cout << *it << std::endl;
}

But at least in the present case it is nicer to use a range-based for loop:
for (auto x: v) std::cout << x << "\n";
(You may also add & after auto to make x a reference to the elements rather than a copy of them. It is then very similar to the above iterator-based approach, but easier to read and write.)

I'm using vs2012 and i think the update KB2781514 changed some setting. All my System.Web.Http in my MVC4 project changed to false and i keeping received this message. I had changed the All file in this project in publish property but its not working. Finally I have to change Copy Local = true one by one and solved this problem.

There are few steps if we dont use "create-react-app",([email protected]) first we should install file-loader as devDedepencie,next step is to add rule in webpack.config

{
    test: /\.(png|jpe?g|gif)$/i,
    loader: 'file-loader',
}

, then in our src directory we should make file called declarationFiles.d.ts(for example) and register modules inside

declare module '*.jpg';
declare module '*.png';

,then restart dev-server. After these steps we can import and use images like in code bellow

import React from 'react';
import image from './img1.png';
import './helloWorld.scss';

const HelloWorld = () => (
  <>
    <h1 className="main">React TypeScript Starter</h1>
        <img src={image} alt="some example image" />
  </>
);
export default HelloWorld;

Works in typescript and also in javacript,just change extension from .ts to .js

Cheers.

The solution of this problem is very simple Just go to the directory where the project installed and open the file with extension ".xcworkspace"

That will solve the problem .

You can't find a consistent reference because it seems to go by at least six different names!

Open a PL/SQL object in the Editor.

Click on the main toolbar or select Session | Toggle Compiling with Debug. This enables debugging.

Compile the object on the database.

Select one of the following options on the Execute toolbar to begin debugging: Execute PL/SQL with debugger () Step over Step into Run to cursor

Other than the advantages listed in the answers given, one more advantage of NestedScrollView over ScrollView is its compatibility with CoordinatorLayout. The ScrollView does not cooperate with the CoordinatorLayout. You have to use NestedScrollView to get "scroll off-screen" behaviour for the toolbar.

Toolbar will not collapse with Scrollview as child of CoordinatorLayout

Have you tried plt.tight_layout()?

with plt.tight_layout() without it:

Or: something like this (use add_axes)

left=[0.1,0.3,0.5,0.7]
width=[0.2,0.2, 0.2, 0.2]
rectLS=[]
for x in left:
   for y in left:
       rectLS.append([x, y, 0.2, 0.2])
axLS=[]
fig=plt.figure()
axLS.append(fig.add_axes(rectLS[0]))
for i in [1,2,3]:
     axLS.append(fig.add_axes(rectLS[i],sharey=axLS[-1]))    
axLS.append(fig.add_axes(rectLS[4]))
for i in [1,2,3]:
     axLS.append(fig.add_axes(rectLS[i+4],sharex=axLS[i],sharey=axLS[-1]))
axLS.append(fig.add_axes(rectLS[8]))
for i in [5,6,7]:
     axLS.append(fig.add_axes(rectLS[i+4],sharex=axLS[i],sharey=axLS[-1]))     
axLS.append(fig.add_axes(rectLS[12]))
for i in [9,10,11]:
     axLS.append(fig.add_axes(rectLS[i+4],sharex=axLS[i],sharey=axLS[-1]))

If you don't need to share axes, then simply axLS=map(fig.add_axes, rectLS)

MP4 is just a container - the video and audio stream inside it will both be encoded in different formats.

Android natively only supports certain types of formats. This is the list here.

Make sure the video and audio encoding type is supported. Just because it says "mp4" doesn't automatically mean it should be playable.

It is possible, just exec it as any other program. Just make sure your script has the proper #! (she-bang) line as the first line of the script, and make sure there are execute permissions on the file.

For example, if it is a bash script put #!/bin/bash at the top of the script, also chmod +x .

Also as for if it's good practice, no it's not, especially for Java, but if it saves you a lot of time porting a large script over, and you're not getting paid extra to do it ;) save your time, exec the script, and put the porting to Java on your long-term todo list.

A simple solution to the problem is nano index.html and git or any other terminal will open the file right on the terminal, then you edit from there.

You see commands at the bottom of the edit page on how to save.

The following regular expression in Python works well for detecting URL(s) in the text:

source_text = '''
text1
text2
http://url.com/bla1/blah1/
text3
text4
http://url.com/bla2/blah2/
text5
text6    '''

import re
url_reg  = r'[a-z]*[:.]+\S+'
result   = re.sub(url_reg, '', source_text)
print(result)

Output:

text1
text2

text3
text4

text5
text6

Running Catalina 10.15.4 I ran the permissions command below to get brew to install

sudo chown -R $(whoami):admin /usr/local/* && sudo chmod -R g+rwx /usr/local/*

Update: created a js fiddle here to see it live: http://jsfiddle.net/HFMvX/

I went through tons of google searches and didn't find anything satisfying. i like how passpack have done it so essentially reverse-engineered their approach, here we go:

function scorePassword(pass) {
    var score = 0;
    if (!pass)
        return score;

    // award every unique letter until 5 repetitions
    var letters = new Object();
    for (var i=0; i<pass.length; i++) {
        letters[pass[i]] = (letters[pass[i]] || 0) + 1;
        score += 5.0 / letters[pass[i]];
    }

    // bonus points for mixing it up
    var variations = {
        digits: /\d/.test(pass),
        lower: /[a-z]/.test(pass),
        upper: /[A-Z]/.test(pass),
        nonWords: /\W/.test(pass),
    }

    var variationCount = 0;
    for (var check in variations) {
        variationCount += (variations[check] == true) ? 1 : 0;
    }
    score += (variationCount - 1) * 10;

    return parseInt(score);
}

Good passwords start to score around 60 or so, here's function to translate that in words:

function checkPassStrength(pass) {
    var score = scorePassword(pass);
    if (score > 80)
        return "strong";
    if (score > 60)
        return "good";
    if (score >= 30)
        return "weak";

    return "";
}

you might want to tune this a bit but i found it working for me nicely

For syntax errors, you need to enable error display in the php.ini. By default these are turned off because you don't want a "customer" seeing the error messages. Check this page in the PHP documentation for information on the 2 directives: error_reporting and display_errors. display_errors is probably the one you want to change. If you can't modify the php.ini, you can also add the following lines to an .htaccess file:

php_flag  display_errors        on
php_value error_reporting       2039

You may want to consider using the value of E_ALL (as mentioned by Gumbo) for your version of PHP for error_reporting to get all of the errors. more info

3 other items: (1) You can check the error log file as it will have all of the errors (unless logging has been disabled). (2) Adding the following 2 lines will help you debug errors that are not syntax errors:

error_reporting(-1);
ini_set('display_errors', 'On');

(3) Another option is to use an editor that checks for errors when you type, such as PhpEd. PhpEd also comes with a debugger which can provide more detailed information. (The PhpEd debugger is very similar to xdebug and integrates directly into the editor so you use 1 program to do everything.)

Cartman's link is also very good: http://www.ibm.com/developerworks/library/os-debug/

All previous answers are great, and I'd like to plug in one more point.

From generative algorithm models, we can derive any distribution; while we can only obtain the conditional distribution P(Y|X) from the discriminative algorithm models(or we can say they are only useful for discriminating Y’s label), and that's why it is called discriminative model. The discriminative model doesn't assume that the X's are independent given the Y($X_i \perp X_{-i} | Y$) and hence is usually more powerful for calculating that conditional distribution.

It seems Yahoo server does some heuristic based on User-Agent in a case Accept header is set to */*.

Accept: text/html

did the trick for me.

e.g.

wget  --header="Accept: text/html" --user-agent="Mozilla/5.0 (Macintosh; Intel Mac OS X 10.8; rv:21.0) Gecko/20100101 Firefox/21.0"  http://yahoo.com

Note: if you don't declare Accept header then wget automatically adds Accept:*/* which means give me anything you have.

For me the issue was with the space in volume mapping that was not escaped. The jenkins job which was running the docker run command had a space in it and as a result docker engine was not able to understand the docker run command.

Just set the last value of the enum to a value large enough to make it the size you would like the enum to be, it should then be that size:

enum value{a=0,b,c,d,e,f,g,h,i,j,l,m,n,last=0xFFFFFFFFFFFFFFFF};

echo "Subject: test" | /usr/sbin/sendmail [email protected]

This enables you to do it within one command line without having to echo a text file. This answer builds on top of @mti2935's answer. So credit goes there.

Well for this, also have a look at org.apache.commons.lang.BooleanUtils#toBoolean(java.lang.String), along with many other useful functions.

JQuery UI makes light work out of creating toggle buttons. Just put this

<label for="myToggleButton">my toggle button caption</label>
<input type="checkbox" id="myToggleButton" />

on your page and then in your body onLoad or your $.ready() (or some object literals init() function if your building an ajax site..) drop some JQuery like so:

$("#myToggleButton").button()

thats it. (don't forget the < label for=...> because JQueryUI uses that for the body of the toggle button..)

From there you just work with it like any other input="checkbox" because that is what the underlying control still is but JQuery UI just skins it to look like a pretty toggle button on screen.

See ?boxplot for all the help you need.

 outline: if ‘outline’ is not true, the outliers are not drawn (as
          points whereas S+ uses lines).

boxplot(x,horizontal=TRUE,axes=FALSE,outline=FALSE)

And for extending the range of the whiskers and suppressing the outliers inside this range:

   range: this determines how far the plot whiskers extend out from the
          box.  If ‘range’ is positive, the whiskers extend to the most
          extreme data point which is no more than ‘range’ times the
          interquartile range from the box. A value of zero causes the
          whiskers to extend to the data extremes.

# change the value of range to change the whisker length
boxplot(x,horizontal=TRUE,axes=FALSE,range=2)

You need to url-escape the ampersand. Use:

var wysiwyg_clean = wysiwyg.replace('&', '%26');

As Wolfram points out, this is nicely handled (along with all the other special characters) by encodeURIComponent.

I used this method to clear the image from picturebox. It may help some one

private void btnClear1_Click(object sender, EventArgs e)
        {

            img1.ImageLocation = null;
        }

You should try SciPy. It has a bunch of useful scientific routines for example, "routines for computing integrals numerically, solving differential equations, optimization, and sparse matrices." It uses the superfast optimized NumPy for its number crunching. See here for installing.

Note that spatial.distance.cosine computes the distance, and not the similarity. So, you must subtract the value from 1 to get the similarity.

from scipy import spatial

dataSetI = [3, 45, 7, 2]
dataSetII = [2, 54, 13, 15]
result = 1 - spatial.distance.cosine(dataSetI, dataSetII)

Here is a much faster solution based on hari's answer. The basic difference is that we keep a set of possible values for cells that don't have a value assigned. So when we try a new value, we only try valid values and we also propagate what this choice means for the rest of the sudoku. In the propagation step, we remove from the set of valid values for each cell the values that already appear in the row, column, or the same block. If only one number is left in the set, we know that the position (cell) has to have that value.

This method is known as forward checking and look ahead (http://ktiml.mff.cuni.cz/~bartak/constraints/propagation.html).

The implementation below needs one iteration (calls of solve) while hari's implementation needs 487. Of course my code is a bit longer. The propagate method is also not optimal.

Just for the record, since SQL 2012 you can use FORMAT, as simple as:

SELECT FORMAT(GETDATE(), 'ddMMyyyy')

(op question is specific about SQL 2008)

I was facing a similar difficulty and none of the solutions presented here were optimal for what I was working on. What I had was a series of functions to display content in a modal and I was trying to refactor it under a single object definition making the functions, methods of the class. The problem came in when I found one of the methods created some nav-buttons inside the modal themselves which used an onClick to one of the functions -- now an object of the class. I have considered (and am still considering) other methods to handle these nav buttons, but I was able to find the variable name for the class itself by sweeping the variables defined in the parent window. What I did was search for anything matching the 'instanceof' my class, and in case there might be more than one, I compared a specific property that was likely to be unique to each instance:

var myClass = function(varName)
{
    this.instanceName = ((varName != null) && (typeof(varName) == 'string') && (varName != '')) ? varName : null;

    /**
     * caching autosweep of window to try to find this instance's variable name
     **/
    this.getInstanceName = function() {
        if(this.instanceName == null)
        {
            for(z in window) {
                if((window[z] instanceof myClass) && (window[z].uniqueProperty === this.uniqueProperty)) {
                    this.instanceName = z;
                    break;
                }
            }
        }
        return this.instanceName;
    }
}

It's fine to manually select each number for a small set of numbers like in your example, but for larger collections you can do a regex search which will do the work for you.

Ctrl + F will open the search bar.

Regex searches are enabled by clicking the ".*" button on the far left.

Type in "\d+" to search for all occurrences of 1 or more digits. Clicking the "Find All" button will select each of these numbers separately.

Then you can use Ctrl + Shift + L to convert the selection into multiple cursors. From here you can do as you like.

Five years late to the party.

It is mentioned in the provided links of the accepted answer, but I think it deserves an explicit answer on SO - dynamically building the query based on provided parameters. E.g.:

Setup

-- drop table Person
create table Person
(
    PersonId INT NOT NULL IDENTITY(1, 1) CONSTRAINT PK_Person PRIMARY KEY,
    FirstName NVARCHAR(64) NOT NULL,
    LastName NVARCHAR(64) NOT NULL,
    Title NVARCHAR(64) NULL
)
GO

INSERT INTO Person (FirstName, LastName, Title)
VALUES ('Dick', 'Ormsby', 'Mr'), ('Serena', 'Kroeger', 'Ms'), 
    ('Marina', 'Losoya', 'Mrs'), ('Shakita', 'Grate', 'Ms'), 
    ('Bethann', 'Zellner', 'Ms'), ('Dexter', 'Shaw', 'Mr'),
    ('Zona', 'Halligan', 'Ms'), ('Fiona', 'Cassity', 'Ms'),
    ('Sherron', 'Janowski', 'Ms'), ('Melinda', 'Cormier', 'Ms')
GO

Procedure

ALTER PROCEDURE spDoSearch
    @FirstName varchar(64) = null,
    @LastName varchar(64) = null,
    @Title varchar(64) = null,
    @TopCount INT = 100
AS
BEGIN
    DECLARE @SQL NVARCHAR(4000) = '
        SELECT TOP ' + CAST(@TopCount AS VARCHAR) + ' *
        FROM Person
        WHERE 1 = 1'

    PRINT @SQL

    IF (@FirstName IS NOT NULL) SET @SQL = @SQL + ' AND FirstName = @FirstName'
    IF (@LastName IS NOT NULL) SET @SQL = @SQL + ' AND FirstName = @LastName'
    IF (@Title IS NOT NULL) SET @SQL = @SQL + ' AND Title = @Title'

    EXEC sp_executesql @SQL, N'@TopCount INT, @FirstName varchar(25), @LastName varchar(25), @Title varchar(64)', 
         @TopCount, @FirstName, @LastName, @Title
END
GO

Usage

exec spDoSearch @TopCount = 3
exec spDoSearch @FirstName = 'Dick'

Pros:

• easy to write and understand
• flexibility - easily generate the query for trickier filterings (e.g. dynamic TOP)

Cons:

• possible performance problems depending on provided parameters, indexes and data volume

Not direct answer, but related to the problem aka the big picture

Usually, these filtering stored procedures do not float around, but are being called from some service layer. This leaves the option of moving away business logic (filtering) from SQL to service layer.

One example is using LINQ2SQL to generate the query based on provided filters:

    public IList<SomeServiceModel> GetServiceModels(CustomFilter filters)
    {
        var query = DataAccess.SomeRepository.AllNoTracking;

        // partial and insensitive search 
        if (!string.IsNullOrWhiteSpace(filters.SomeName))
            query = query.Where(item => item.SomeName.IndexOf(filters.SomeName, StringComparison.OrdinalIgnoreCase) != -1);
        // filter by multiple selection
        if ((filters.CreatedByList?.Count ?? 0) > 0)
            query = query.Where(item => filters.CreatedByList.Contains(item.CreatedById));
        if (filters.EnabledOnly)
            query = query.Where(item => item.IsEnabled);

        var modelList = query.ToList();
        var serviceModelList = MappingService.MapEx<SomeDataModel, SomeServiceModel>(modelList);
        return serviceModelList;
    }

Pros:

• dynamically generated query based on provided filters. No parameter sniffing or recompile hints needed
• somewhat easier to write for those in the OOP world
• typically performance friendly, since "simple" queries will be issued (appropriate indexes are still needed though)

Cons:

• LINQ2QL limitations may be reached and forcing a downgrade to LINQ2Objects or going back to pure SQL solution depending on the case
• careless writing of LINQ might generate awful queries (or many queries, if navigation properties loaded)

In general I would consider setting up of an environment variable (like PYTHONPATH) to be a bad practice. While this might be fine for a one off debugging but using this as
a regular practice might not be a good idea.

Usage of environment variable leads to situations like "it works for me" when some one
else reports problems in the code base. Also one might carry the same practice with the test environment as well, leading to situations like the tests running fine for a particular developer but probably failing when some one launches the tests.

In this case, they are the same. None is a singleton object (there only ever exists one None).

is checks to see if the object is the same object, while == just checks if they are equivalent.

For example:

p = [1]
q = [1]
p is q # False because they are not the same actual object
p == q # True because they are equivalent

But since there is only one None, they will always be the same, and is will return True.

p = None
q = None
p is q # True because they are both pointing to the same "None"

You could just write it out in multiline like this,

$ cat dict.go
package main

import "fmt"

func main() {
        items := map[string]interface{}{
                "foo": map[string]int{
                        "strength": 10,
                        "age": 2000,
                },
                "bar": map[string]int{
                        "strength": 20,
                        "age": 1000,
                },
        }
        for key, value := range items {
                fmt.Println("[", key, "] has items:")
                for k,v := range value.(map[string]int) {
                        fmt.Println("\t-->", k, ":", v)
                }

        }
}

And the output:

$ go run dict.go
[ foo ] has items:
        --> strength : 10
        --> age : 2000
[ bar ] has items:
        --> strength : 20
        --> age : 1000

Solved the issue for me :

    Range(Cells(1, 1), Cells(100, 1)).Select

    For Each xCell In Selection

    xCell.Value = CDate(xCell.Value)

    Next xCell
