Programs & Examples On #Httplib2

I had the same issue however with doing an upload of a very large file using a python-requests client posting to a nginx+uwsgi backend.

What ended up being the cause was the the backend had a cap on the max file size for uploads lower than what the client was trying to send.

The error never showed up in our uwsgi logs since this limit was actually one imposed by nginx.

Upping the limit in nginx removed the error.

Here cascade, in the context of remove, means that the children are removed if you remove the parent. Not the association. If you are using Hibernate as your JPA provider, you can do it using hibernate specific cascade.

Take a look at sprintf() and family.

You can use the following command. The SET will set the input from the user console to the variable comment and then you can use that variable using %comment%

SET /P comment=Comment: 
echo %comment%
pause

Are you using php 5.4 on your local? the render line is using the new way of initializing arrays. Try replacing ["title" => "Welcome "] with array("title" => "Welcome ")

BigInteger is immutable. The javadocs states that add() "[r]eturns a BigInteger whose value is (this + val)." Therefore, you can't change sum, you need to reassign the result of the add method to sum variable.

sum = sum.add(BigInteger.valueOf(i));

assuming the item numbers are unique, a VLOOKUP should get you the information you need.

first value would be =VLOOKUP(E1,A:B,2,FALSE), and the same type of formula to retrieve the second value would be =VLOOKUP(E1,C:D,2,FALSE). Wrap them in an IFERROR if you want to return anything other than #N/A if there is no corresponding value in the item column(s)

The using syntax has an advantage when used within templates. If you need the type abstraction, but also need to keep template parameter to be possible to be specified in future. You should write something like this.

template <typename T> struct whatever {};

template <typename T> struct rebind
{
  typedef whatever<T> type; // to make it possible to substitue the whatever in future.
};

rebind<int>::type variable;

template <typename U> struct bar { typename rebind<U>::type _var_member; }

But using syntax simplifies this use case.

template <typename T> using my_type = whatever<T>;

my_type<int> variable;
template <typename U> struct baz { my_type<U> _var_member; }

For #4, the closest thing to starting java with a jar file for your app is a new feature in Python 2.6, executable zip files and directories.

python myapp.zip

Where myapp.zip is a zip containing a __main__.py file which is executed as the script file to be executed. Your package dependencies can also be included in the file:

__main__.py
mypackage/__init__.py
mypackage/someliblibfile.py

You can also execute an egg, but the incantation is not as nice:

# Bourn Shell and derivatives (Linux/OSX/Unix)
PYTHONPATH=myapp.egg python -m myapp

rem Windows 
set PYTHONPATH=myapp.egg
python -m myapp

This puts the myapp.egg on the Python path and uses the -m argument to run a module. Your myapp.egg will likely look something like:

myapp/__init__.py
myapp/somelibfile.py

And python will run __init__.py (you should check that __file__=='__main__' in your app for command line use).

Egg files are just zip files so you might be able to add __main__.py to your egg with a zip tool and make it executable in python 2.6 and run it like python myapp.egg instead of the above incantation where the PYTHONPATH environment variable is set.

More information on executable zip files including how to make them directly executable with a shebang can be found on Michael Foord's blog post on the subject.

If you just deserialize to dynamic you will get a JObject back. You can get what you want by using an ExpandoObject.

var converter = new ExpandoObjectConverter();    
dynamic message = JsonConvert.DeserializeObject<ExpandoObject>(jsonString, converter);

As I'm beginner for vba, I'm willing to get a deep knowledge of vba of how all excel in-built functions work form there back.

So as on the above question I have putted my basic efforts.

Function multi_add(a As Range, ParamArray b() As Variant) As Double

    Dim ele As Variant

    Dim i As Long

    For Each ele In a
        multi_add = a + ele.Value **- a**
    Next ele

    For i = LBound(b) To UBound(b)
        For Each ele In b(i)
            multi_add = multi_add + ele.Value
        Next ele
    Next i

End Function

- a: This is subtracted for above code cause a count doubles itself so what values you adds it will add first value twice.

Note: An incorrect revision of this answer was edited out. Please review all answers.

A subselect in the WHERE clause to retrieve the greatest BALANCE aggregated over all rows. If multiple ID values share that balance value, all would be returned.

SELECT 
  ID,
  BALANCE
FROM CUSTOMERS
WHERE BALANCE = (SELECT MAX(BALANCE) FROM CUSTOMERS)

The following should work

$ad->getcodes()->distinct()->count('pid');

I'll add a bit to this old thread.

Usually you would use

$ echo "$FOO"

However, I've had problems even with this syntax. Consider the following script.

#!/bin/bash
curl_opts="-s --noproxy * -O"
curl $curl_opts "$1"

The * needs to be passed verbatim to curl, but the same problems will arise. The above example won't work (it will expand to filenames in the current directory) and neither will \*. You also can't quote $curl_opts because it will be recognized as a single (invalid) option to curl.

curl: option -s --noproxy * -O: is unknown
curl: try 'curl --help' or 'curl --manual' for more information

Therefore I would recommend the use of the bash variable $GLOBIGNORE to prevent filename expansion altogether if applied to the global pattern, or use the set -f built-in flag.

#!/bin/bash
GLOBIGNORE="*"
curl_opts="-s --noproxy * -O"
curl $curl_opts "$1"  ## no filename expansion

Applying to your original example:

me$ FOO="BAR * BAR"

me$ echo $FOO
BAR file1 file2 file3 file4 BAR

me$ set -f
me$ echo $FOO
BAR * BAR

me$ set +f
me$ GLOBIGNORE=*
me$ echo $FOO
BAR * BAR

I'd do something along these lines:

$myitems =
@([pscustomobject]@{name="Joe";age=32;info="something about him"},
[pscustomobject]@{name="Sue";age=29;info="something about her"},
[pscustomobject]@{name="Cat";age=12;info="something else"})

Note that this only works in PowerShell 3, but since you did not mention the version in your question I'm assuming this does not matter for you.

Update

It has been mentioned in comments that if you do the following:

$younger = $myitems | Where-Object { $_.age -lt 20 } 
Write-Host "people younger than 20: $($younger.Length)" 

You won't get 1 as you might expect. This happens when a single pscustomobject is returned. Now this is not a problem for most of other objects in PowerShell, because they have surrogate properties for Length and Count. Unfortunately pscustomobject does not. This is fixed in PowerShell 6.1.0. You can work around this by using operator @():

$younger = @($myitems | Where-Object { $_.age -lt 20 })

For more background see here and here.

Update 2

In PowerShell 5 one can use Classes to acheive similar functionality. For example you can define a class like this:

class Person {
    [string]$name
    [int]$age
    [string]$info; `
`
    Person(
    [string]$name,
    [int]$age,
    [string]$info
    ){
        $this.name = $name
        $this.age = $age
        $this.info = $info
    }
}

Backticks here are so that you could copy and paste it to the command line, they are not required in a script. Once the class is defined you can the create an array the usual way:

$myitems =@([Person]::new("Joe",32,"something about him"),
[Person]::new("Sue",29,"something about her"),
[Person]::new("Cat",12,"something else"))

Note that this way does not have the drawback mentioned in the previous update, even in PowerShell 5.

Update 3

You can also intialize a class object with a hashtable, similar to the first example. For that you need to make sure that a default contructor defined. If you do not provide any constructors, one will be created for you, but if you provide a non-default one, default constructor won't be there and you will need to define it explicitly. Here is an example with default constructor that is auto-created:

class Person {
    [string]$name
    [int]$age
    [string]$info;
}

With that you can:

$person = @([Person]@{name='Kevin';age=36;info="something about him"}
[Person]@{name='Sue';age=29;info="something about her"}
[Person]@{name='Cat';age=12;info="something else"})

This is a bit more verbose, but also a bit more explicit. Thanks to @js2010 for pointing this out.

You can try something like:

var str = "a,d,k";
str.replace(/,/g, "");

In addition to what @inkedmn has pointed out, a static member is at the class level. Therefore, the said member is loaded into memory by the JVM once for that class (when the class is loaded). That is, there aren't n instances of a static member loaded for n instances of the class to which it belongs.

According to VBA help on SET statement it sets a reference to an object.so if you change a property the actual object will also changes.

Dim newObj as Object
Set var1=Object1(same type as Object)
Set var2=Object1(same type as Object)
Set var3=Object1(same type as Object)
Set var4=Object1(same type as Object)
Var1.property1=NewPropertyValue

the other Vars properties also changes,so:

Var1.property1=Var2.property1=Var3.property1=Var4.property1=Object1.Property1=NewpropertyValue`

actualy all vars are the same!

Save yourself the headache of trying to find a "built-in" solution.

There isn't a good answer, and the hugely upvoted answer in this thread is wrong.

npm install is-number

In JavaScript, it's not always as straightforward as it should be to reliably check if a value is a number. It's common for devs to use +, -, or Number() to cast a string value to a number (for example, when values are returned from user input, regex matches, parsers, etc). But there are many non-intuitive edge cases that yield unexpected results:

console.log(+[]); //=> 0
console.log(+''); //=> 0
console.log(+'   '); //=> 0
console.log(typeof NaN); //=> 'number'

I had the same error message. For me changing pooling=False to ;pooling=true;Max Pool Size=200 in the connection string fixed the problem.

For all users on a specific database, do the following:

# psql
\c your_database
select grantee, table_catalog, privilege_type, table_schema, table_name from information_schema.table_privileges order by grantee, table_schema, table_name;

I am working on an angular js app, andhavecome across a similar issue. What i did was display the image from the db, then created a button to remove or keep the current image. If the user decided to keep the current image, i changed the ng-submit attribute to another function whihc doesnt require image validation, and updated the record in the db without touching the original image path name. The remove image function also changed the ng-submit attribute value back to a function that submits the form and includes image validation and upload. Also a bit of javascript to slide the into view to upload a new image.

You could simply use CSS animated text generator. There are pre-created templates already

0 will get printed.

As in C++ true refers to 1 and false refers to 0.

In case, you want to print false instead of 0,then you have to sets the boolalpha format flag for the str stream.

When the boolalpha format flag is set, bool values are inserted/extracted by their textual representation: either true or false, instead of integral values.

#include <iostream>
int main()
{
  std::cout << std::boolalpha << false << std::endl;
}

output:

false

Using Guava you can easily combine different type of criteria. For your specific solution you can use:

value = CharMatcher.inRange('0', '9')
        .or(CharMatcher.inRange('a', 'z')
        .or(CharMatcher.inRange('A', 'Z'))).retainFrom(value)

If you take a look at the source code of Spring Data JPA, and particularly the PartTreeJpaQuery class, you will see that is tries to instantiate PartTree. Inside that class the following regular expression

private static final Pattern PREFIX_TEMPLATE = Pattern.compile("^(find|read|get|count|query)(\\p{Lu}.*?)??By")

should indicate what is allowed and what's not.

Of course if you try to add such a method you will actually see that is does not work and you get the full stacktrace.

I should note that I was using looking at version 1.5.0.RELEASE of Spring Data JPA

if linux

if install by apt-get

service memcached stop
service memcached restart

if install by source code

Usage: /etc/init.d/memcached {start|stop|restart|force-reload|status}

can also simply kill $pid to stop

org.json.simple.JSONArray resultantJson = new org.json.simple.JSONArray();

        org.json.JSONArray o1 = new org.json.JSONArray("[{\"one\":[],\"two\":\"abc\"}]");
        org.json.JSONArray o2 = new org.json.JSONArray("[{\"three\":[1,2],\"four\":\"def\"}]");


        resultantJson.addAll(o1.toList());
        resultantJson.addAll(o2.toList());

To convert serialize object to String and String to Object

stringToBean(beanToString(new LoginMdp()), LoginMdp.class);

public static String beanToString(Object object) throws IOException {

    ObjectMapper objectMapper = new ObjectMapper();
    StringWriter stringEmp = new StringWriter();
    objectMapper.configure(SerializationFeature.INDENT_OUTPUT, true);
    objectMapper.writeValue(stringEmp, object);
    return stringEmp.toString();
}

public static <T> T stringToBean(String content, Class<T> valueType) throws IOException {
    return new ObjectMapper().readValue(content, valueType);
}

For Windows:

Step 1. Make a batch file with the below commands and call the file w.bat.

Step 2. Copy the below contents in w.bat, and save it in any of the folders which are in %path% of your Windows system

echo ***Get phone in Wi-Fi mode***
echo ***Get phone in Wi-Fi mode***

adb devices
echo ***Remove cable from the phone now***
adb tcpip 9000

adb connect 192.168.1.1:9000
adb connect 192.168.1.2:9000
adb connect 192.168.1.3:9000
adb connect 192.168.1.4:9000
adb connect 192.168.1.5:9000
adb connect 192.168.1.6:9000

//<-- Till here -->

Step 3. Connect your phone and PC with a cable

Step 4. Ensure the phone is in Wi-Fi mode

Step 5. Remove the cable when the batch file tells you to

Step 6. Type w.bat on the Windows prompt (start -> run -> type CMD, press Enter) (black screen is Windows DOS prompt), if you copied it in one of the path folders then you can run from anywhere, else run from the folder where you created this file.

The output of the batch file will be something like this:

C:\Windows\System32>w

C:\Windows\System32>echo ***Get phone in Wi-Fi mode***
***Get phone in Wi-Fi mode***

C:\Windows\System32>echo ***Get phone in Wi-Fi mode***
***Get phone in Wi-Fi mode***

C:\Windows\System32>adb devices
List of devices attached
d4e9f06 device

C:\Windows\System32>echo ***Remove cable from the Phone now***
***Remove cable from the Phone now***

C:\Windows\System32>adb tcpip 9000
restarting in TCP mode port: 9000

C:\Windows\System32>adb connect 192.168.1.1:9000
unable to connect to 192.168.1.1:9000:9000

C:\Windows\System32>adb connect 192.168.1.2:9000
connected to 192.168.1.2:9000

C:\Windows\System32>adb connect 192.168.1.3:9000
unable to connect to 192.168.1.3:9000:9000

C:\Windows\System32>adb connect 192.168.1.4:9000
unable to connect to 192.168.1.4:9000:9000

C:\Windows\System32>adb connect 192.168.1.5:9000
unable to connect to 192.168.1.5:9000:9000

C:\Windows\System32>adb connect 192.168.1.6:9000
unable to connect to 192.168.1.6:9000:9000

Note 1: Find this in the output, (ignore all ->unable to connect<- errors)

connected to xxx.xxx.x.x:9000

If you see this in the result, just remove the cable from PC and go to Eclipse and run to install the app on the device; that should be it.

Note 2: DISCONNECT OR TO SWITCH WIRELESS MODE OFF: Type the below command. It should say restarting in USB mode - at this stage PC and computer should NOT be connected with a cable:

C:\Users\dell>adb usb
restarting in USB mode

Note 3: Steps to find the IP address of the phone (taken from Stack Overflow)

Find IP address of MY PHONE:

a. Dial *#*#4636#*#* to open the Testing menu.
b. In the Wi-Fi information menu: click Wi-Fi Status
c. Wi-Fi status can be blank for the first time
d. Click Refresh Status
e. In the IPaddr: <<IP ADDRESS OF THE PHONE IS LISTED>>

Note 4: My Phone Wi-Fi connection IP address range typically is as the mentioned IP addresses below,

192.168.1.1

192.168.1.2

192.168.1.3

192.168.1.4

192.168.1.5

192.168.1.6

Note 5: if you get any other sequence of IP addresses which keep getting reassigned to your phone, you can just change the IP address in the w.bat file.

Note 6: This is a brute-force method, which eliminates all manual labor to keep finding IP address and connecting to Eclipse / Wi-Fi.

SUCCESS Note 7: So in short, the regular activity would be something like this:

Step 1. Connect PC and Wi-Fi via a cable
Step 2. Start CMD - to go to Windows DOS prompt
Step 3. Type "w"
Step 4. Find connected command in the output
Step 5. Success, remove cable and start using Eclipse

Adding n seconds to 1970-01-01 will give you a UTC date because n, the Unix timestamp, is the number of seconds that have elapsed since 00:00:00 Coordinated Universal Time (UTC), Thursday, 1 January 1970.

In SQL Server 2016, you can convert one time zone to another using AT TIME ZONE. You just need to know the name of the time zone in Windows standard format:

SELECT *
FROM (VALUES (1514808000), (1527854400)) AS Tests(UnixTimestamp)
CROSS APPLY (SELECT DATEADD(SECOND, UnixTimestamp, '1970-01-01') AT TIME ZONE 'UTC') AS CA1(UTCDate)
CROSS APPLY (SELECT UTCDate AT TIME ZONE 'Pacific Standard Time') AS CA2(LocalDate)

| UnixTimestamp | UTCDate                    | LocalDate                  |
|---------------|----------------------------|----------------------------|
| 1514808000    | 2018-01-01 12:00:00 +00:00 | 2018-01-01 04:00:00 -08:00 |
| 1527854400    | 2018-06-01 12:00:00 +00:00 | 2018-06-01 05:00:00 -07:00 |

Or simply:

SELECT *, DATEADD(SECOND, UnixTimestamp, '1970-01-01') AT TIME ZONE 'UTC' AT TIME ZONE 'Pacific Standard Time'
FROM (VALUES (1514808000), (1527854400)) AS Tests(UnixTimestamp)

| UnixTimestamp | LocalDate                  |
|---------------|----------------------------|
| 1514808000    | 2018-01-01 04:00:00 -08:00 |
| 1527854400    | 2018-06-01 05:00:00 -07:00 |

Notes:

• You can chop off the timezone information by casting DATETIMEOFFSET to DATETIME.
• The conversion takes daylight savings time into account. Pacific time was UTC-08:00 on January 2018 and UTC-07:00 on Jun 2018.

Just copy your favicon on: /yourappname/mainapp(ex:core)/static/mainapp(ex:core)/img

Then go to your mainapp template(ex:base.html) and just copy this, after {% load static %} because you must load first the statics.

<link href="{% static 'core/img/favi_x.png' %}" rel="shortcut icon" type="image/png" />

The method jQuery (v1.10) uses to find this is:

var doc = document.documentElement;
var left = (window.pageXOffset || doc.scrollLeft) - (doc.clientLeft || 0);
var top = (window.pageYOffset || doc.scrollTop)  - (doc.clientTop || 0);

That is:

• It tests for window.pageXOffset first and uses that if it exists.
• Otherwise, it uses document.documentElement.scrollLeft.
• It then subtracts document.documentElement.clientLeft if it exists.

The subtraction of document.documentElement.clientLeft / Top only appears to be required to correct for situations where you have applied a border (not padding or margin, but actual border) to the root element, and at that, possibly only in certain browsers.

Here's some performance measurements from my machine. Relevant in case this is performed for small inputs in a long-running loop:

import functools, operator, timeit
import numpy as np

def multiply_numpy(iterable):
    return np.prod(np.array(iterable))

def multiply_functools(iterable):
    return functools.reduce(operator.mul, iterable)

def multiply_manual(iterable):
    prod = 1
    for x in iterable:
        prod *= x

    return prod

sizesToTest = [5, 10, 100, 1000, 10000, 100000]

for size in sizesToTest:
    data = [1] * size

    timerNumpy = timeit.Timer(lambda: multiply_numpy(data))
    timerFunctools = timeit.Timer(lambda: multiply_functools(data))
    timerManual = timeit.Timer(lambda: multiply_manual(data))

    repeats = int(5e6 / size)
    resultNumpy = timerNumpy.timeit(repeats)
    resultFunctools = timerFunctools.timeit(repeats)
    resultManual = timerManual.timeit(repeats)
    print(f'Input size: {size:>7d} Repeats: {repeats:>8d}    Numpy: {resultNumpy:.3f}, Functools: {resultFunctools:.3f}, Manual: {resultManual:.3f}')

Results:

Input size:       5 Repeats:  1000000    Numpy: 4.670, Functools: 0.586, Manual: 0.459
Input size:      10 Repeats:   500000    Numpy: 2.443, Functools: 0.401, Manual: 0.321
Input size:     100 Repeats:    50000    Numpy: 0.505, Functools: 0.220, Manual: 0.197
Input size:    1000 Repeats:     5000    Numpy: 0.303, Functools: 0.207, Manual: 0.185
Input size:   10000 Repeats:      500    Numpy: 0.265, Functools: 0.194, Manual: 0.187
Input size:  100000 Repeats:       50    Numpy: 0.266, Functools: 0.198, Manual: 0.185

You can see that Numpy is quite a bit slower on smaller inputs, since it allocates an array before multiplication is performed. Also, watch out for the overflow in Numpy.

Opera, Safari, Firefox and Chrome now all share a set of enhanced Array methods for optimizing many common loops.

You may not need all of them, but they can be very useful, or would be if every browser supported them.

Mozilla Labs published the algorithms they and WebKit both use, so that you can add them yourself.

filter returns an array of items that satisfy some condition or test.

every returns true if every array member passes the test.

some returns true if any pass the test.

forEach runs a function on each array member and doesn't return anything.

map is like forEach, but it returns an array of the results of the operation for each element.

These methods all take a function for their first argument and have an optional second argument, which is an object whose scope you want to impose on the array members as they loop through the function.

Ignore it until you need it.

indexOf and lastIndexOf find the appropriate position of the first or last element that matches its argument exactly.

"...by a class and a div."

I assume when you say "div" you mean "id"? Try this:

$('#test2.test1').prop('checked', true);

No need to muck about with your [attributename=value] style selectors because id has its own format as does class, and they're easily combined although given that id is supposed to be unique it should be enough on its own unless your meaning is "select that element only if it currently has the specified class".

Or more generally to select an input where you want to specify a multiple attribute selector:

$('input:radio[class=test1][id=test2]').prop('checked', true);

That is, list each attribute with its own square brackets.

Note that unless you have a pretty old version of jQuery you should use .prop() rather than .attr() for this purpose.

By printing the hashcode of the String/StringBuffer object after any append operation also prove, String object is getting recreated internally every time with new values rather than using the same String object.

public class MutableImmutable {

/**
 * @param args
 */
public static void main(String[] args) {
    System.out.println("String is immutable");
    String s = "test";
    System.out.println(s+"::"+s.hashCode());
    for (int i = 0; i < 10; i++) {
        s += "tre";
        System.out.println(s+"::"+s.hashCode());
    }

    System.out.println("String Buffer is mutable");

    StringBuffer strBuf = new StringBuffer("test");
    System.out.println(strBuf+"::"+strBuf.hashCode());
    for (int i = 0; i < 10; i++) {
        strBuf.append("tre");
        System.out.println(strBuf+"::"+strBuf.hashCode());
    }

 }

}

Output: It prints object value along with its hashcode

This is how I do. I have added explanation to understand what the heck is going on.

Initialize Local Repository

• first initialize Git with

  git init

• Add all Files for version control with

  git add .

• Create a commit with message of your choice

  git commit -m 'AddingBaseCode'

Initialize Remote Repository

• Create a project on GitHub and copy the URL of your project . as shown below:

  

Link Remote repo with Local repo

• Now use copied URL to link your local repo with remote GitHub repo. When you clone a repository with git clone, it automatically creates a remote connection called origin pointing back to the cloned repository. The command remote is used to manage set of tracked repositories.

  git remote add origin https://github.com/hiteshsahu/Hassium-Word.git

Synchronize

• Now we need to merge local code with remote code. This step is critical otherwise we won't be able to push code on GitHub. You must call 'git pull' before pushing your code.

  git pull origin master --allow-unrelated-histories

Commit your code

• Finally push all changes on GitHub

  git push -u origin master

If your method has no side effects, and doesn't return anything, then it's not doing anything.

If your method does some computation and returns the result of that computation, you can obviously enough assert that the result returned is correct.

If your code doesn't return anything but does have side effects, you can call the code and then assert that the correct side effects have happened. What the side effects are will determine how you do the checks.

In your example, you are calling static methods from your non-returning functions, which makes it tricky unless you can inspect that the result of all those static methods are correct. A better way - from a testing point of view - is to inject actual objects in that you call methods on. You can then use something like EasyMock or Mockito to create a Mock Object in your unit test, and inject the mock object into the class. The Mock Object then lets you assert that the correct functions were called, with the correct values and in the correct order.

For example:

private ErrorFile errorFile;

public void setErrorFile(ErrorFile errorFile) {
    this.errorFile = errorFile;
}

private void method1(arg1) {
    if (arg1.indexOf("$") == -1) {

        //Add an error message 
        errorFile.addErrorMessage("There is a dollar sign in the specified parameter");
    }
}

Then in your test you can write:

public void testMethod1() {
    ErrorFile errorFile = EasyMock.createMock(ErrorFile.class);
    errorFile.addErrorMessage("There is a dollar sign in the specified parameter");
    EasyMock.expectLastCall(errorFile);
    EasyMock.replay(errorFile);

    ClassToTest classToTest = new ClassToTest();
    classToTest.setErrorFile(errorFile);
    classToTest.method1("a$b");

    EasyMock.verify(errorFile); // This will fail the test if the required addErrorMessage call didn't happen
}

I found that I also had to set the UserMapping option when creating a new login and this solved the problem for me. Hope that helps anyone that also found themselves stuck here!

Edit: Setting the login as db owner solved the next problem, too

Those who are getting ClassDefNotFoundError try to move that Three jar files to lib folder of your Project,it worked for me!!

Try to connect to the repository using command line SVN to see if you get a similar error.

$ svn checkout http://svn.python.org/projects/peps/trunk

If you keep getting the error, it is probably an issue with your proxy server. I have found that I can't check out internet based SVN projects at work because the firewall blocks most HTTP commands. It only allows GET, POST and others necessary for browsing.

// Pear Mail Library
require_once "Mail.php";

    'From' => $from,

Use Measure-Command

Example

Measure-Command { <your command here> | Out-Host }

The pipe to Out-Host allows you to see the output of the command, which is otherwise consumed by Measure-Command.

I had this problem. I had the DLL included into the project and the setting to Copy Local was true by default. Don't know why it started, since that DLL was in the project for a long while. I've heard some mentions of ReSharper possibly removing it, but I can't say I've ran a unused reference removal.

What helped me was: - Running "Update-Package Microsoft.Web.Infrastructure -Reinstall" on the project, which updated the whole solution, but didn't end up helping in and of itself. - Then I went through the projects' references and set the Copy Local to false, and then back to true. This actually resulted in a line being added into CSPROJ file under the DLL reference: True. Or something along the lines... Either way, now the build was copying the files as expected.

Turns out that the post (or rather the whole table) was locked by the very same connection that I tried to update the post with.

I had a opened record set of the post that was created by:

Set RecSet = Conn.Execute()

This type of recordset is supposed to be read-only and when I was using MS Access as database it did not lock anything. But apparently this type of record set did lock something on MS SQL Server 2012 because when I added these lines of code before executing the UPDATE SQL statement...

RecSet.Close
Set RecSet = Nothing

...everything worked just fine.

So bottom line is to be careful with opened record sets - even if they are read-only they could lock your table from updates.

As others stated, it's likely failing because the requested key doesn't exist in the array. I have a helper function here that takes the array, the suspected key, as well as a default return in the event the key does not exist.

    protected function _getArrayValue($array, $key, $default = null)
    {
        if (isset($array[$key])) return $array[$key];
        return $default;
    }

hope it helps.

Officially it's Ctrl+F11 & Ctrl+F12 or KEYPAD 7 & KEYPAD 9.

In practise it's a bit quirky.

1. Specifically it's Left Ctrl+F11 and Left Ctrl+F12 to switch to previous orientation and next orientation respectively.

2. You have to release Ctrl before you can rotate again.

3. KEYPAD 7 and KEYPAD 9 only work with Num Lock OFF (so they're acting as Home & PageUp rather than 7 & 9).

4. The only orientations are vertically upright and rotated one quarter-turn anti-clockwise.

Maybe a bit too much info for such a simple question, but it drove me half-mad finding this out.

Note: This was tested on Android SDK R16 and a very old keyboard, modern keyboards may behave differently.

Either you experienced database connection issue or you missed any of the hibernate configurations to connect to database such as database DIALECT.

Happens if your database server was disconnected due to network related issue.

If you're using spring boot along with hibernate connected to Oracle Db, use

hibernate.dialect=org.hibernate.dialect.HSQLDialect
hibernate.show_sql=true
hibernate.hbm2ddl.auto=update
hibernate.generate_statistics=true
entitymanager.packagesToScan: com

select column_name, data_type, character_maximum_length    
from INFORMATION_SCHEMA.COLUMNS
where table_name = 'Table1'

I think in Postgres you can play with formats for example if you want dd/mm/yyyy

TO_CHAR(submit_time, 'DD/MM/YYYY') as submit_date

Maybe a simpler solution is to set an overlay in front of your map using FrameLayout or RelativeLayout and treating them as regular buttons in your activity. You should declare your layers in back to front order, e.g., map before buttons. I modified your layout, simplified it a little bit. Try the following layout and see if it works for you:

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"

A simple way is to write:

-std=c++11

in the Other Options section of the compiler flags. You could do this on a per-project basis (Project -> Build Options), and/or set it as a default option in the Settings -> Compilers part.

Some projects may require -std=gnu++11 which is like C++11 but has some GNU extensions enabled.

If using g++ 4.9, you can use -std=c++14 or -std=gnu++14.

var variables still have a type - and the compiler error message says this type must be established during the declaration.

The specific request (assigning an initial null value) can be done, but I don't recommend it. It doesn't provide an advantage here (as the type must still be specified) and it could be viewed as making the code less readable:

var x = (String)null;

Which is still "type inferred" and equivalent to:

String x = null;

The compiler will not accept var x = null because it doesn't associate the null with any type - not even Object. Using the above approach, var x = (Object)null would "work" although it is of questionable usefulness.

Generally, when I can't use var's type inference correctly then

1. I am at a place where it's best to declare the variable explicitly; or
2. I should rewrite the code such that a valid value (with an established type) is assigned during the declaration.

The second approach can be done by moving code into methods or functions.

In short, no. You cannot autowire or manually wire static fields in Spring. You'll have to write your own logic to do this.

If anyone else came here like me trying to find a solution for the error:

'env' is not recognized as an internal or external command

The reason I got this is that I was migrating an angular solution from a mac development machine over to a windows 10 desktop. This is how I resolved it.

1. run npm install --save-dev cross-env

2. go into my package.json file and change all the script references from env <whatever> to cross-env <whatever>

Then my commands like: npm run start:some_random_environment_var now run fine on Windows 10.

Replacing cdc_ string

You can use vim or perl to replace the cdc_ string in chromedriver. See answer by @Erti-Chris Eelmaa to learn more about that string and how it's a detection point.

Using vim or perl prevents you from having to recompile source code or use a hex-editor.

Make sure to make a copy of the original chromedriver before attempting to edit it.

Our goal is to alter the cdc_ string, which looks something like $cdc_lasutopfhvcZLmcfl.

The methods below were tested on chromedriver version 2.41.578706.

Using Vim

vim /path/to/chromedriver

After running the line above, you'll probably see a bunch of gibberish. Do the following:

1. Replace all instances of cdc_ with dog_ by typing :%s/cdc_/dog_/g.
   • dog_ is just an example. You can choose anything as long as it has the same amount of characters as the search string (e.g., cdc_), otherwise the chromedriver will fail.
2. To save the changes and quit, type :wq! and press return.
   • If you need to quit without saving changes, type :q! and press return.

Using Perl

The line below replaces all cdc_ occurrences with dog_. Credit to Vic Seedoubleyew:

perl -pi -e 's/cdc_/dog_/g' /path/to/chromedriver

Make sure that the replacement string (e.g., dog_) has the same number of characters as the search string (e.g., cdc_), otherwise the chromedriver will fail.

Wrapping Up

To verify that all occurrences of cdc_ were replaced:

grep "cdc_" /path/to/chromedriver

If no output was returned, the replacement was successful.

Go to the altered chromedriver and double click on it. A terminal window should open up. If you don't see killed in the output, you've successfully altered the driver.

Make sure that the name of the altered chromedriver binary is chromedriver, and that the original binary is either moved from its original location or renamed.

My Experience With This Method

I was previously being detected on a website while trying to log in, but after replacing cdc_ with an equal sized string, I was able to log in. Like others have said though, if you've already been detected, you might get blocked for a plethora of other reasons even after using this method. So you may have to try accessing the site that was detecting you using a VPN, different network, etc.

I hope this will be helpful.. If I understood the problem

One checkbox to rule them all

For people still looking for plugin to control checkboxes through one that's lightweight, has out-of-the-box support for UniformJS and iCheck and gets unchecked when at least one of controlled checkboxes is unchecked (and gets checked when all controlled checkboxes are checked of course) I've created a jQuery checkAll plugin.

Feel free to check the examples on documentation page.

For this question example all you need to do is:

$( '#select_all' ).checkall({
    target: 'input[type="checkbox"][name="select"]'
});

Isn't that clear and simple?

Without changing the markup or using JavaScript, you'd pretty much have to alter the text color as knut mentions, or set text-indent: -1000em;

IE6 will not read the :hover selector on anything other than an anchor element, so you will have to use something like Dean Edwards' IE7.

Really though, you're better off putting the text in some kind of element (like p or span or a) and setting that to display: none; on hover.

An extension to the answers from R. Martinho Fernandes and Class Skeleton: Their answers show how to use typename std::underlying_type<EnumType>::type or std::underlying_type_t<EnumType> to convert your enumeration value with a static_cast to a value of the underlying type. Compared to a static_cast to some specific integer type, like, static_cast<int> this has the benefit of being maintenance friendly, because when the underlying type changes, the code using std::underlying_type_t will automatically use the new type.

This, however, is sometimes not what you want: Assume you wanted to print out enumeration values directly, for example to std::cout, like in the following example:

enum class EnumType : int { Green, Blue, Yellow };
std::cout << static_cast<std::underlying_type_t<EnumType>>(EnumType::Green);

If you later change the underlying type to a character type, like, uint8_t, then the value of EnumType::Green will not be printed as a number, but as a character, which is most probably not what you want. Thus, you sometimes would rather convert the enumeration value into something like "underlying type, but with integer promotion where necessary".

It would be possible to apply the unary operator+ to the result of the cast to force integer promotion if necessary. However, you can also use std::common_type_t (also from header file <type_traits>) to do the following:

enum class EnumType : int { Green, Blue, Yellow };
std::cout << static_cast<std::common_type_t<int, std::underlying_type_t<EnumType>>>(EnumType::Green);

Preferrably you would wrap this expression in some helper template function:

template <class E>
constexpr std::common_type_t<int, std::underlying_type_t<E>>
enumToInteger(E e) {
    return static_cast<std::common_type_t<int, std::underlying_type_t<E>>>(e);
}

Which would then be more friendly to the eyes, be maintenance friendly with respect to changes to the underlying type, and without need for tricks with operator+:

std::cout << enumToInteger(EnumType::Green);

You can try this one it is short

SystemClock.sleep(7000);

WARNING: Never, ever, do this on a UI thread.

Use this to sleep eg. background thread.

        });

Without creating tmp Handler. Also this solution is better than @tronman because we do not retain view by Handler. Also we don't have problem with Handler created at bad thread ;)

Documentation

public static void sleep (long ms)

Added in API level 1

Waits a given number of milliseconds (of uptimeMillis) before returning. Similar to sleep(long), but does not throw InterruptedException; interrupt() events are deferred until the next interruptible operation. Does not return until at least the specified number of milliseconds has elapsed.

Parameters

ms to sleep before returning, in milliseconds of uptime.

Code for postDelayed from View class:

/**
 * <p>Causes the Runnable to be added to the message queue, to be run
 * after the specified amount of time elapses.
 * The runnable will be run on the user interface thread.</p>
 *
 * @param action The Runnable that will be executed.
 * @param delayMillis The delay (in milliseconds) until the Runnable
 *        will be executed.
 *
 * @return true if the Runnable was successfully placed in to the
 *         message queue.  Returns false on failure, usually because the
 *         looper processing the message queue is exiting.  Note that a
 *         result of true does not mean the Runnable will be processed --
 *         if the looper is quit before the delivery time of the message
 *         occurs then the message will be dropped.
 *
 * @see #post
 * @see #removeCallbacks
 */
public boolean postDelayed(Runnable action, long delayMillis) {
    final AttachInfo attachInfo = mAttachInfo;
    if (attachInfo != null) {
        return attachInfo.mHandler.postDelayed(action, delayMillis);
    }
    // Assume that post will succeed later
    ViewRootImpl.getRunQueue().postDelayed(action, delayMillis);

I don't think you need to remove "#" from href. Following works with Angularjs 1.2.10

<a href="#/" ng-click="logout()">Logout</a>

Please confirm that your firewall is allowing outbound traffic and that you are not being blocked by antivirus software.

I received the same issue and the culprit was antivirus software.

I was ultimately able to resolve the solution by setting the column type in the flat file connection to be of type "database date [DT_DBDATE]"

Apparently the differences between these date formats are as follow:

DT_DATE A date structure that consists of year, month, day, and hour.

DT_DBDATE A date structure that consists of year, month, and day.

DT_DBTIMESTAMP A timestamp structure that consists of year, month, hour, minute, second, and fraction

By changing the column type to DT_DBDATE the issue was resolved - I attached a Data Viewer and the CYCLE_DATE value was now simply "12/20/2010" without a time component, which apparently resolved the issue.

If you have Login in a seperate folder within your project make sure that where you are using it you do:

using FootballLeagueSystem.[Whatever folder you are using]

The answer of rakensi from Getting path of an R script is the most correct and really brilliant IMHO. Yet, it's still a hack incorporating a dummy function. I'm quoting it here, in order to have it easier found by others.

sourceDir <- getSrcDirectory(function(dummy) {dummy})

This gives the directory of the file where the statement was placed (where the dummy function is defined). It can then be used to set the working direcory and use relative paths e.g.

setwd(sourceDir)
source("other.R")

or to create absolute paths

 source(paste(sourceDir, "/other.R", sep=""))

To disable UIWebView scrolling you could use the following line of code:

[ObjWebview setUserInteractionEnabled:FALSE];

In this example, ObjWebview is of type UIWebView.

If you are storing values via any programming language

Here is an example in C#

To store date you have to convert it first and then store it

insert table1 (foodate)
   values (FooDate.ToString("MM/dd/yyyy"));

FooDate is datetime variable which contains your date in your format.

Use CultureInfo class to change your culture info.

var dutchCultureInfo = CultureInfo.CreateSpecificCulture("nl-NL");
var date1 = DateTime.ParseExact(date, "dd.MM.yyyy HH:mm:ss", dutchCultureInfo);

From the documentation:

We can add to a list in many ways:

assert [1,2] + 3 + [4,5] + 6 == [1, 2, 3, 4, 5, 6]
assert [1,2].plus(3).plus([4,5]).plus(6) == [1, 2, 3, 4, 5, 6]
    //equivalent method for +
def a= [1,2,3]; a += 4; a += [5,6]; assert a == [1,2,3,4,5,6]
assert [1, *[222, 333], 456] == [1, 222, 333, 456]
assert [ *[1,2,3] ] == [1,2,3]
assert [ 1, [2,3,[4,5],6], 7, [8,9] ].flatten() == [1, 2, 3, 4, 5, 6, 7, 8, 9]

def list= [1,2]
list.add(3) //alternative method name
list.addAll([5,4]) //alternative method name
assert list == [1,2,3,5,4]

list= [1,2]
list.add(1,3) //add 3 just before index 1
assert list == [1,3,2]
list.addAll(2,[5,4]) //add [5,4] just before index 2
assert list == [1,3,5,4,2]

list = ['a', 'b', 'z', 'e', 'u', 'v', 'g']
list[8] = 'x'
assert list == ['a', 'b', 'z', 'e', 'u', 'v', 'g', null, 'x']

You can also do:

def myNewList = myList << "fifth"

1. press [win] + Pause
2. Advanced settings
3. System variables
4. Append ;C:\python27\Scripts to the end of Path variable
5. Restart console

Here is my modification of the currently accepted answer, which I believe it's a little faster and shorter:

private static Random random = new Random();

private string RandomString(int size) {
    StringBuilder builder = new StringBuilder(size);
    for (int i = 0; i < size; i++)
        builder.Append((char)random.Next(0x41, 0x5A));
    return builder.ToString();
}

Notice I didn't use all the multiplication, Math.floor(), Convert etc.

EDIT: random.Next(0x41, 0x5A) can be changed to any range of Unicode characters.

EDIT: ASIHTTPRequest has been abandoned by the developer. It's still really good IMO, but you should probably look elsewhere now.

I'd highly recommend using the ASIHTTPRequest library if you are handling HTTPS. Even without https it provides a really nice wrapper for stuff like this and whilst it's not hard to do yourself over plain http, I just think the library is nice and a great way to get started.

The HTTPS complications are far from trivial in various scenarios, and if you want to be robust in handling all the variations, you'll find the ASI library a real help.

First, open a command prompt After type a bellow commands.

check a version itself Easily :

Form Windows:

pip installation :

pip install pip

pip Version check:

pip --version 

I use a similar approach like @Ofaim

private bool jobSaved = true;
private bool JobSaved    
{ 
    get => jobSaved; 
    set
    {
        if (value == jobSaved) return;
        jobSaved = value;

        OnPropertyChanged();
        OnPropertyChanged("EnableSaveButton");
    }
}

public bool EnableSaveButton => !jobSaved;

I am using Cent OS 6.6 with Apache and for me error log files are in

You just need to wrap items with linear layouts which have layout_weight. To have items horizontally separated, use this

Don't know for sure, but it sounds like it is still submitting. I quick solution would be to change your (guessing at your code here):

<input type="submit" value="Submit" onclick="checkform()">

to a button:

<input type="button" value="Submit" onclick="checkform()">

That way your form still gets submitted (from the else part of your checkform()) and it shouldn't be reloading the page.

There are other, perhaps better, ways of handling it but this works in the mean time.

You can use the following code to get the value of the first column of the selected row of your table.

int column = 0;
int row = table.getSelectedRow();
String value = table.getModel().getValueAt(row, column).toString();

With get() method you get a collection (all data that match the query), try to use first() instead, it return only one element, like this:

$about = Page::where('page', 'about-me')->first();

Execute the following on your terminal to get the latest stable version:

sudo gem install cocoapods

Add --pre to get the latest pre release:

sudo gem install cocoapods --pre

If you originally installed the cocoapods gem using sudo, you should use that command again.

Later on, when you're actively using CocoaPods by installing pods, you will be notified when new versions become available with a CocoaPods X.X.X is now available, please update message.

For those who use docker-compose, it’s really easy to set a password without any config file like redis.conf. Here’s how you would normally use the official Redis image:

redis:
    image: 'redis:4-alpine'
    ports:
      - '6379:6379'

And here’s all you need to change to set a custom password:

  redis:
    image: 'redis:4-alpine'
    command: redis-server --requirepass yourpassword
    ports:
      - '6379:6379'

Everything will start up as normal and your Redis server will be protected by a password.

For details, this blog post seems to support the idea.

$("body").css("background","green"); //jQuery

document.body.style.backgroundColor = "green"; //javascript

so many ways are there I think it is very easy and simple

Demo On Plunker

For a UWP app:

XAML

C#

public ObservableCollection<Type> Results

For Rails 4, see this answer.

For Rails 3.x, configure a logger in config/environments/test.rb:

config.logger = Logger.new(STDOUT)
config.logger.level = Logger::ERROR

This will interleave any errors that are logged during testing to STDOUT. You may wish to route the output to STDERR or use a different log level instead.

Sending these messages to both the console and a log file requires something more robust than Ruby's built-in Logger class. The logging gem will do what you want. Add it to your Gemfile, then set up two appenders in config/environments/test.rb:

logger = Logging.logger['test']
logger.add_appenders(
    Logging.appenders.stdout,
    Logging.appenders.file('example.log')
)
logger.level = :info
config.logger = logger

If you can use jQuery, look at load. You could then set your function to run after your element finishes loading.

For example, consider a page with a simple image:

<img src="book.png" alt="Book" id="book" />

The event handler can be bound to the image:

$('#book').load(function() {
  // Handler for .load() called.
});

If you need all elements on the current window to load, you can use

$(window).load(function () {
  // run code
});

If you cannot use jQuery, the plain Javascript code is essentially the same amount of (if not less) code:

window.onload = function() {
  // run code
};

As I found the best way is doing is preloading a stylesheet that contains the font face, and then let browser to load it automatically. I used the font-face in other locations (in the html page), but then I could observe the font changing effect briefly.

<link href="fonts.css?family=Open+Sans" rel="preload stylesheet" as="style">

then in the font.css file, specify as following.

@font-face {
  font-family: 'Open Sans';
  font-style: normal;
  font-weight: 400;
  src: local('Open Sans Regular'), local('OpenSans-Regular'),
       url('open-sans-v16-latin-regular.woff2') format('woff2'); /*  Super Modern Browsers */
}

You can't assign a name to fonts when it's preloaded through link tag (correct me if I was wrong I couldn't find a way yet), and thus you have to use font-face to assign the name to the font. Even though it's possible to load a font through link tag, it's not recommended as you can't assign a name to the font with it. Without a name as with font-face, you won't be able to use it anywhere in the web page. According to gtmetrix, style sheet loads at the beginning, then rest of the scripts/style by order, then the font before dom is loaded, and therefore you don't see font changing effect.

My implementation

import $ from 'jquery';

$(document).ready(() => {
  $('#whatDescribesYouSelectInput').on('change', (e) => {
    if (e.target.value === 'Other') {
      $('#whatDescribesYouOtherInput').attr('type', 'text');
      $('#specifyLabel').show();
    } else {
      $('#whatDescribesYouOtherInput').attr('type', 'hidden');
      $('#specifyLabel').hide();
    }
  });
});

I couldn't get the first method to work, and I know this is an old topic, but this is what I ended up doing for a solution:

=IF(ISNA(MATCH(A1,B:B,0)),"Not Matched", A1)

Basically, MATCH A1 to Column B exactly (the 0 stands for match exactly to a value in Column B). ISNA tests for #N/A response which match will return if the no match is found. Finally, if ISNA is true, write "Not Matched" to the selected cell, otherwise write the contents of the matched cell.

btnSubmit_Click(btnSubmit,EventArgs.Empty);

This question is quite old, but with Hibernate 5.1.10, there are some new better comfortable solution.

Lazy loading works except for the parent side of a @OneToOne association. This is because Hibernate has no other way of knowing whether to assign a null or a Proxy to this variable. More details you can find in this article

• You can activate lazy loading bytecode enhancement
• Or, you can just remove the parent side and use the client side with @MapsId as explained in the article above. This way, you will find that you don’t really need the parent side since the child shares the same id with the parent so you can easily fetch the child by knowing the parent id .

We use compiled code to distribute to users who do not have access to the source code. Basically to stop inexperienced programers accidentally changing something or fixing bugs without telling us.

Because the STL is not an "everything" library. It contains, essentially, the minimum structures needed to build things.

There is a easy way to this.

-- Disable all the constraint in database
EXEC sp_msforeachtable 'ALTER TABLE ? NOCHECK CONSTRAINT all'

-- Enable all the constraint in database
EXEC sp_msforeachtable 'ALTER TABLE ? WITH CHECK CHECK CONSTRAINT all'

Reference SQL SERVER – Disable All the Foreign Key Constraint in Database – Enable All the Foreign Key Constraint in Database

The readonly keyword is used to declare a member variable a constant, but allows the value to be calculated at runtime. This differs from a constant declared with the const modifier, which must have its value set at compile time. Using readonly you can set the value of the field either in the declaration, or in the constructor of the object that the field is a member of.

Also use it if you don't want to have to recompile external DLLs that reference the constant (since it gets replaced at compile time).

You can check whether the variable is a number like this: $val -is [int]

This will work for numeric values, but not if the number is wrapped in quotes:

1 -is [int]
True
"1" -is [int]
False

Design patterns are just tools--kind of like library functions. If you know that they are there and their approximate function, you can go dig them out of a book when needed.

There is nothing magic about design patterns, and any good programmer figured 90% of them out for themselves before any books came out. For the most part I consider the books to be most useful at simply defining names for the various patterns so we can discuss them more easily.

In CSS3:

input[type=radio] {content:url(mycheckbox.png)}
input[type=radio]:checked {content:url(mycheckbox-checked.png)}

In reality:

<span class=fakecheckbox><input type=radio><img src="checkbox.png" alt=""></span>

@media screen {.fakecheckbox img {display:none}}
@media print {.fakecheckbox input {display:none;}}

and you'll need Javascript to keep <img> and radios in sync (and ideally insert them there in a first place).

I've used <img>, because browsers are usually configured not to print background-image. It's better to use image than another control, because image is non-interactive and less likely to cause problems.

If you have to run composer with sudo, you should change the directory of composer to

I've been reading this post because I thought I wanted to do the same thing. I have a similar situation for an application I'm working on. And really it's a matter of testing more than practicality.

After reading these answers, especially the one given by Michael Borgwardt, I realized the work flow that needs to exist:

1. If the user navigates to the login screen, check for an existing session. If one exists bypass the login screen and send them to the welcome screen.
2. If the user (in my case) navigates to the enrollment screen, check for an existing session. If one exists, let the user know you're going to log that session out. If they agree, log out, and begin enrollment.

This will solve the problem of user's seeing "another user's" data in their session. They aren't really seeing "another user's" data in their session, they're really seeing the data from the only session they have open. Clearly this causes for some interesting data as some operations overwrite some session data and not others so you have a combination of data in that single session.

Now, to address the testing issue. The only viable approach would be to leverage Preprocessor Directives to determine if cookie-less sessions should be used. See, by building in a specific configuration for a specific environment I'm able to make some assumptions about the environment and what it's used for. This would allow me to technically have two users logged in at the same time and the tester could test multiple scenarios from the same browser session without ever logging out of any of those server sessions.

However, this approach has some serious caveats. Not least of which is the fact that what the tester is testing is not what's going to run in production.

So I think I've got to say, this is ultimately a bad idea.

I took the answer from PirateApp and made it reusable. If you include this script it will transform all selects with the class '.dropdown' to searchable dropdowns.

$('.dropdown').each(function(index, dropdown) {

  //Find the input search box
  let search = $(dropdown).find('.search');

  //Find every item inside the dropdown
  let items = $(dropdown).find('.dropdown-item');

  //Capture the event when user types into the search box
  $(search).on('input', function() {
    filter($(search).val().trim().toLowerCase())
  });

  //For every word entered by the user, check if the symbol starts with that word
  //If it does show the symbol, else hide it
  function filter(word) {
    let length = items.length
    let collection = []
    let hidden = 0
    for (let i = 0; i < length; i++) {
      if (items[i].value.toString().toLowerCase().includes(word)) {
        $(items[i]).show()
      } else {
        $(items[i]).hide()
        hidden++
      }
    }

    //If all items are hidden, show the empty view
    if (hidden === length) {
      $(dropdown).find('.dropdown_empty').show();
    } else {
      $(dropdown).find('.dropdown_empty').hide();
    }
  }

  //If the user clicks on any item, set the title of the button as the text of the item
  $(dropdown).find('.dropdown-menu').find('.menuItems').on('click', '.dropdown-item', function() {
    $(dropdown).find('.dropdown-toggle').text($(this)[0].value);
    $(dropdown).find('.dropdown-toggle').dropdown('toggle');
  })
});

If you wish to log all output to a file AND output it to a text file then you can do the following. It's a bit hacky but it works:

import logging
debug = input("Debug or not")
if debug == "1":
    logging.basicConfig(level=logging.DEBUG, filename='./OUT.txt')
    old_print = print
    def print(string):
        old_print(string)
        logging.info(string)
print("OMG it works!")

EDIT: Note that this does not log errors unless you redirect sys.stderr to sys.stdout

EDIT2: A second issue is that you have to pass 1 argument unlike with the builtin function.

EDIT3: See the code before to write stdin and stdout to console and file with stderr only going to file

import logging, sys
debug = input("Debug or not")
if debug == "1":
    old_input = input
    sys.stderr.write = logging.info
    def input(string=""):
        string_in = old_input(string)
        logging.info("STRING IN " + string_in)
        return string_in
    logging.basicConfig(level=logging.DEBUG, filename='./OUT.txt')
    old_print = print
    def print(string="", string2=""):
        old_print(string, string2)
        logging.info(string)
        logging.info(string2)
print("OMG")
b = input()
print(a) ## Deliberate error for testing

Beside the solutions listed in the answers, you can use the Linux command "top". It provides a dynamic real-time view of the running system, and it gives the CPU and memory usage for the whole system, along with for every program, in percentage:

top

to filter by a program PID:

top -p <PID>

To filter by a program name:

top | grep <PROCESS NAME>

"top" provides also some fields such as:

VIRT -- Virtual Image (kb): The total amount of virtual memory used by the task

RES -- Resident size (kb): The non-swapped physical memory a task has used ; RES = CODE + DATA.

DATA -- Data+Stack size (kb): The amount of physical memory devoted to other than executable code, also known as the 'data resident set' size or DRS.

SHR -- Shared Mem size (kb): The amount of shared memory used by a task. It simply reflects memory that could be potentially shared with other processes.

Reference here.

An easier solution (tested on SQL Server 2014 SP1 CU6)

Code:

DECLARE @Date date = SYSDATETIME();

DECLARE @Time time(0) = SYSDATETIME();

SELECT CAST(CONCAT(@Date, ' ', @Time) AS datetime2(0));

This would also work given a table with a specific date and a specific time field. I use this method frequently given that we have vendor data that uses date and time in two separate fields.

There could be security issues with common methods for auto-login. One of the most easiest ways is documented below:

• Running Putty from the Windows Command Line

And as for the part the executes the command In putty UI, Connection>SSH> there's a field for remote command.

4.17 The SSH panel

The SSH panel allows you to configure options that only apply to SSH sessions.

4.17.1 Executing a specific command on the server

In SSH, you don't have to run a general shell session on the server. Instead, you can choose to run a single specific command (such as a mail user agent, for example). If you want to do this, enter the command in the "Remote command" box. http://the.earth.li/~sgtatham/putty/0.53/htmldoc/Chapter4.html

in short, your answers might just as well be similar to the text below:

• let Putty run command in remote server

May be useful:

The code that calls the Trigger should go after the event is called.

For example, I have some code that I want to be executed when #expense_tickets value is changed, and also, when page is reload

$(function() { 

  $("#expense_tickets").change(function() {
    // code that I want to be executed when #expense_tickets value is changed, and also, when page is reload
  });

  // now we trigger the change event
  $("#expense_tickets").trigger("change");

})

Dude, Just python test.py in your terminal.

f = open('/home/hduser/Desktop/data.csv' , 'r')

x = f.read().split()
f.close()

y = ' '.join(x)
f = open('/home/hduser/Desktop/data.csv','w')
f.write(y)
f.close()

Jacob Smullyan wrote a utility called pesterfish which uses effbot's ElementTree to convert XML to JSON.

newTH.setAttribute("id", "#");

function removeColumn(#){
// remove column #
}

Google App Engine users : If you're moving from Django to Jinja2, and looking to replace the date filter, note that the % formatting codes are different.

It depends on what the zip contains. Take a look to see if it got content.jar and artifacts.jar. If it does, it is an archived updated site. Install from it the same way as you install from a remote site.

If the zip doesn't contain content.jar and artifacts.jar, go to your Eclipse install's dropins directory, create a subfolder (name doesn't matter) and expand your zip into that folder. Restart Eclipse.

When a script generates an html form and that form's action http POSTs back to the same form.

You need to add style="overflow-y:scroll;" to the div tag. (This will force a scrollbar on the vertical).

If you only want a scrollbar when needed, just do overflow-y:auto;

This version builds on Robert Elliot's, but I'm not 100% sure of its efficacy.

// There are a few dependencies added by one of the Scala plugins that this cannot reach.
task downloadDependencies {
  description "Pre-downloads *most* dependencies"
  doLast {
    configurations.getAsMap().each { name, config ->
      println "Retrieving dependencies for $name"
      try {
        config.files
      } catch (e) {
        project.logger.info e.message // some cannot be resolved, silentlyish skip them
      }
    }
  }
}

I tried putting it into configuration instead of action (by removing doLast) and it broke zinc. I worked around it, but the end result was the same with or without. So, I left it as an explicit state. It seems to work enough to reduce the dependencies that have to be downloaded later, but not eliminate them in my case. I think one of the Scala plugins adds dependencies later.

Use this function:

function is_checkbox(selector) {
    var $result = $(selector);
    return $result[0] && $result[0].type === 'checkbox';
};

Or this jquery plugin:

$.fn.is_checkbox = function () { return this.is(':checkbox'); };

There is a nice, simple and tested way of doing that:

/* Create table-value string: */
CREATE TYPE [String_List] AS TABLE ([Your_String_Element] varchar(max) PRIMARY KEY);
GO
/* Create procedure which takes this table as parameter: */

CREATE PROCEDURE [dbo].[usp_ListCheck]
@String_List_In [String_List] READONLY  
AS   
SELECT a.*
FROM [dbo].[Tags] a
JOIN @String_List_In b ON a.[Name] = b.[Your_String_Element];

I have started using this method to fix the issues we had with the entity framework (was not robust enough for our application). So we decided to give the Dapper (same as Stack) a chance. Also specifying your string list as table with PK column fix your execution plans a lot. Here is a good article of how to pass a table into Dapper - all fast and CLEAN.

if (data.length != 0) {
    var opts = "";
    for (i in data)
        opts += "<option value='"+data[i][value]+"'>"+data[i][text]+"</option>";

    $("#myselect").empty().append(opts);
}

This manipulates the DOM only once after first building a giant string.

Create a class which extends HttpServlet and put @WebServlet annotation on it containing the desired URL the servlet should listen on.

@WebServlet("/yourServletURL")
public class YourServlet extends HttpServlet {}

And just let <form action> point to this URL. I would also recommend to use POST method for non-idempotent requests. You should make sure that you have specified the name attribute of the HTML form input fields (<input>, <select>, <textarea> and <button>). This represents the HTTP request parameter name. Finally, you also need to make sure that the input fields of interest are enclosed inside the desired form and thus not outside.

Here are some examples of various HTML form input fields:

<form action="${pageContext.request.contextPath}/yourServletURL" method="post">
    <p>Normal text field.        
    <input type="text" name="name" /></p>

    <p>Secret text field.        
    <input type="password" name="pass" /></p>

    <p>Single-selection radiobuttons.        
    <input type="radio" name="gender" value="M" /> Male
    <input type="radio" name="gender" value="F" /> Female</p>

    <p>Single-selection checkbox.
    <input type="checkbox" name="agree" /> Agree?</p>

    <p>Multi-selection checkboxes.
    <input type="checkbox" name="role" value="USER" /> User
    <input type="checkbox" name="role" value="ADMIN" /> Admin</p>

    <p>Single-selection dropdown.
    <select name="countryCode">
        <option value="NL">Netherlands</option>
        <option value="US">United States</option>
    </select></p>

    <p>Multi-selection listbox.
    <select name="animalId" multiple="true" size="2">
        <option value="1">Cat</option>
        <option value="2">Dog</option>
    </select></p>

    <p>Text area.
    <textarea name="message"></textarea></p>

    <p>Submit button.
    <input type="submit" name="submit" value="submit" /></p>
</form>

Create a doPost() method in your servlet which grabs the submitted input values as request parameters keyed by the input field's name (not id!). You can use request.getParameter() to get submitted value from single-value fields and request.getParameterValues() to get submitted values from multi-value fields.

@Override
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    String name = request.getParameter("name");
    String pass = request.getParameter("pass");
    String gender = request.getParameter("gender");
    boolean agree = request.getParameter("agree") != null;
    String[] roles = request.getParameterValues("role");
    String countryCode = request.getParameter("countryCode");
    String[] animalIds = request.getParameterValues("animalId");
    String message = request.getParameter("message");
    boolean submitButtonPressed = request.getParameter("submit") != null;
    // ...
}

Do if necessary some validation and finally persist it in the DB the usual JDBC/DAO way.

User user = new User(name, pass, roles);
userDAO.save(user);

The solutions posted here did not work well for me, so I did a mixture of the ones of this question and the following question: Is it possible to create multi-level ordered list in HTML?

/* Numbered lists like 1, 1.1, 2.2.1... */
ol li {display:block;} /* hide original list counter */
ol > li:first-child {counter-reset: item;} /* reset counter */
ol > li {counter-increment: item; position: relative;} /* increment counter */
ol > li:before {content:counters(item, ".") ". "; position: absolute; margin-right: 100%; right: 10px;} /* print counter */

If you are using Bootstrap 3, you can use Florin's method, or use a custom CSS file.

If you use Bootstrap less source instead of processed css files, you can directly change it in bootstrap/less/variables.less.

Fabrício's answer is spot on; but I wanted to complement his answer with something less technical, which focusses on an analogy to help explain the concept of asynchronicity.

An Analogy...

Yesterday, the work I was doing required some information from a colleague. I rang him up; here's how the conversation went:

Me: Hi Bob, I need to know how we foo'd the bar'd last week. Jim wants a report on it, and you're the only one who knows the details about it.

Bob: Sure thing, but it'll take me around 30 minutes?

Me: That's great Bob. Give me a ring back when you've got the information!

At this point, I hung up the phone. Since I needed information from Bob to complete my report, I left the report and went for a coffee instead, then I caught up on some email. 40 minutes later (Bob is slow), Bob called back and gave me the information I needed. At this point, I resumed my work with my report, as I had all the information I needed.

Imagine if the conversation had gone like this instead;

Me: Hi Bob, I need to know how we foo'd the bar'd last week. Jim want's a report on it, and you're the only one who knows the details about it.

Bob: Sure thing, but it'll take me around 30 minutes?

Me: That's great Bob. I'll wait.

And I sat there and waited. And waited. And waited. For 40 minutes. Doing nothing but waiting. Eventually, Bob gave me the information, we hung up, and I completed my report. But I'd lost 40 minutes of productivity.

This is asynchronous vs. synchronous behavior

This is exactly what is happening in all the examples in our question. Loading an image, loading a file off disk, and requesting a page via AJAX are all slow operations (in the context of modern computing).

Rather than waiting for these slow operations to complete, JavaScript lets you register a callback function which will be executed when the slow operation has completed. In the meantime, however, JavaScript will continue to execute other code. The fact that JavaScript executes other code whilst waiting for the slow operation to complete makes the behaviorasynchronous. Had JavaScript waited around for the operation to complete before executing any other code, this would have been synchronous behavior.

var outerScopeVar;    
var img = document.createElement('img');

// Here we register the callback function.
img.onload = function() {
    // Code within this function will be executed once the image has loaded.
    outerScopeVar = this.width;
};

// But, while the image is loading, JavaScript continues executing, and
// processes the following lines of JavaScript.
img.src = 'lolcat.png';
alert(outerScopeVar);

In the code above, we're asking JavaScript to load lolcat.png, which is a sloooow operation. The callback function will be executed once this slow operation has done, but in the meantime, JavaScript will keep processing the next lines of code; i.e. alert(outerScopeVar).

This is why we see the alert showing undefined; since the alert() is processed immediately, rather than after the image has been loaded.

In order to fix our code, all we have to do is move the alert(outerScopeVar) code into the callback function. As a consequence of this, we no longer need the outerScopeVar variable declared as a global variable.

var img = document.createElement('img');

img.onload = function() {
    var localScopeVar = this.width;
    alert(localScopeVar);
};

img.src = 'lolcat.png';

You'll always see a callback is specified as a function, because that's the only* way in JavaScript to define some code, but not execute it until later.

Therefore, in all of our examples, the function() { /* Do something */ } is the callback; to fix all the examples, all we have to do is move the code which needs the response of the operation into there!

^{* Technically you can use eval() as well, but eval() is evil for this purpose}

How do I keep my caller waiting?

You might currently have some code similar to this;

function getWidthOfImage(src) {
    var outerScopeVar;

    var img = document.createElement('img');
    img.onload = function() {
        outerScopeVar = this.width;
    };
    img.src = src;
    return outerScopeVar;
}

var width = getWidthOfImage('lolcat.png');
alert(width);

However, we now know that the return outerScopeVar happens immediately; before the onload callback function has updated the variable. This leads to getWidthOfImage() returning undefined, and undefined being alerted.

To fix this, we need to allow the function calling getWidthOfImage() to register a callback, then move the alert'ing of the width to be within that callback;

function getWidthOfImage(src, cb) {     
    var img = document.createElement('img');
    img.onload = function() {
        cb(this.width);
    };
    img.src = src;
}

getWidthOfImage('lolcat.png', function (width) {
    alert(width);
});

... as before, note that we've been able to remove the global variables (in this case width).

There is another user case where final keyword can be used i.e. in a method argument:

public void showCaseFinalArgumentVariable(final int someFinalInt){

   someFinalInt = 9; // won't compile as the argument is final

}

Can be used for variable which should not be changed.

Use this:

<a href="<?php echo(($_SERVER['HTTPS'] ? 'https://' : 'http://').$_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"]); ?>">Whatever</a>

It will create a HREF using the current URL...

I came here and followed above answer. But mismatch in the Order of data type caused an error. The below description from another answer will come handy.

Are the results above the same as the sequence of columns in your table? because oracle is strict in column orders. this example below produces an error:

create table test1_1790 (
col_a varchar2(30),
col_b number,
col_c date);

create table test2_1790 (
col_a varchar2(30),
col_c date,
col_b number);

select * from test1_1790
union all
select * from test2_1790;

ORA-01790: expression must have same datatype as corresponding expression

As you see the root cause of the error is in the mismatching column ordering that is implied by the use of * as column list specifier. This type of errors can be easily avoided by entering the column list explicitly:

select col_a, col_b, col_c from test1_1790 union all select col_a, col_b, col_c from test2_1790; A more frequent scenario for this error is when you inadvertently swap (or shift) two or more columns in the SELECT list:

select col_a, col_b, col_c from test1_1790
union all
select col_a, col_c, col_b from test2_1790;

OR if the above does not solve your problem, how about creating an ALIAS in the columns like this: (the query is not the same as yours but the point here is how to add alias in the column.)

SELECT id_table_a, 
       desc_table_a, 
       table_b.id_user as iUserID, 
       table_c.field as iField
UNION
SELECT id_table_a, 
       desc_table_a, 
       table_c.id_user as iUserID, 
       table_c.field as iField

Another way to do this, which I personally find slightly more convenient and intuitive (without having to remember the --args parameter), is to compile normally, and use r arg1 arg2 arg3 directly from within gdb, like so:

$ gcc -g *.c *.h
$ gdb ./a.out
(gdb) r arg1 arg2 arg3

You can do the following while read loop, that will be fed by the result of the grep command using the so called process substitution:

while IFS= read -r result
do
    #whatever with value $result
done < <(grep "xyz" abc.txt)

This way, you don't have to store the result in a variable, but directly "inject" its output to the loop.

Note the usage of IFS= and read -r according to the recommendations in BashFAQ/001: How can I read a file (data stream, variable) line-by-line (and/or field-by-field)?:

The -r option to read prevents backslash interpretation (usually used as a backslash newline pair, to continue over multiple lines or to escape the delimiters). Without this option, any unescaped backslashes in the input will be discarded. You should almost always use the -r option with read.

In the scenario above IFS= prevents trimming of leading and trailing whitespace. Remove it if you want this effect.

Regarding the process substitution, it is explained in the bash hackers page:

Process substitution is a form of redirection where the input or output of a process (some sequence of commands) appear as a temporary file.

@ModelAttribute is a Spring mapping of request parameters to a particular object type. so your parameters might look like userClient.username and userClient.firstName, etc. as MockMvc imitates a request from a browser, you'll need to pass in the parameters that Spring would use from a form to actually build the UserClient object.

(i think of ModelAttribute is kind of helper to construct an object from a bunch of fields that are going to come in from a form, but you may want to do some reading to get a better definition)

If you don't know that you want to insert it at position #3, but you know the key that you want to insert it after, I cooked up this little function after seeing this question.

/**
     * Inserts any number of scalars or arrays at the point
     * in the haystack immediately after the search key ($needle) was found,
     * or at the end if the needle is not found or not supplied.
     * Modifies $haystack in place.
     * @param array &$haystack the associative array to search. This will be modified by the function
     * @param string $needle the key to search for
     * @param mixed $stuff one or more arrays or scalars to be inserted into $haystack
     * @return int the index at which $needle was found
     */                         
    function array_insert_after(&$haystack, $needle = '', $stuff){
        if (! is_array($haystack) ) return $haystack;

        $new_array = array();
        for ($i = 2; $i < func_num_args(); ++$i){
            $arg = func_get_arg($i);
            if (is_array($arg)) $new_array = array_merge($new_array, $arg);
            else $new_array[] = $arg;
        }

        $i = 0;
        foreach($haystack as $key => $value){
            ++$i;
            if ($key == $needle) break;
        }

        $haystack = array_merge(array_slice($haystack, 0, $i, true), $new_array, array_slice($haystack, $i, null, true));

        return $i;
    }

Here's a codepad fiddle to see it in action: http://codepad.org/5WlKFKfz

Note: array_splice() would have been a lot more efficient than array_merge(array_slice()) but then the keys of your inserted arrays would have been lost. Sigh.

Try this MEX file for ACTUALLY calling Python from MATLAB not the other way around as others suggest. It provides fairly decent integration : http://algoholic.eu/matpy/

You can do something like this easily:

[X,Y]=meshgrid(-10:0.1:10,-10:0.1:10);
Z=sin(X)+cos(Y);
py_export('X','Y','Z')
stmt = sprintf(['import matplotlib\n' ...
'matplotlib.use(''Qt4Agg'')\n' ...
'import matplotlib.pyplot as plt\n' ...
'from mpl_toolkits.mplot3d import axes3d\n' ...
'f=plt.figure()\n' ...
'ax=f.gca(projection=''3d'')\n' ...
'cset=ax.plot_surface(X,Y,Z)\n' ...
'ax.clabel(cset,fontsize=9,inline=1)\n' ...
'plt.show()']);
py('eval', stmt);

$date = new \DateTime("now", new \DateTimeZone('Asia/Calcutta') );
         $day = $date->format('D');
         $weekendnaame = weekedName();
         $weekid =$weekendnaame[$day];
          $dayname = 0;
        $weekiarray = weekendArray($weekid);
        foreach ($weekiarray as $key => $value) {
            if (in_array($value, $request->get('week_id')))
          {
            $dayname = $key+1;
            break;
          }
        }


weeknDate($dayname),

function weeked(){
  $week = array("1"=>"Sunday", "2"=>"Monday", "3"=>"Tuesday", "4"=>"Wednesday", "5"=>"Thursday", "6"=>"Friday", "7"=>"Saturday");
  return $week;
}
function weekendArray($day){
        $favcolor = $day;

switch ($favcolor) {
  case 1:
    $array = array(2,3,4,5,6,7,1);
    break;
  case 2:
    $array = array(3,4,5,6,7,1,2);
    break;
  case 3:
    $array = array(4,5,6,7,1,2,3);
    break;
    case 4:
    $array = array(5,6,7,1,2,3,4);
    break;
    case 5:
    $array = array(6,7,1,2,3,4,5);
    break;
    case 6:
    $array = array(7,1,2,3,4,5,6);
    break;
     case 7:
    $array = array(1,2,3,4,5,6,7);
    break;
  default:
    $array = array(1,2,3,4,5,6,7);
}
return  $array;
}
function weekedName(){
  $week = array("Sun"=>0,"Mun"=>1,"Tue"=>3,"Wed"=>4,"Thu"=>5,"Fri"=>6,"Sat"=>7);
  return $week;
}

DateTime dt = this.dateTimePicker1.Value.Date;

You can even try below option:

<a href="javascript:show_more_menu();">More >>></a>

This solution might also help :

$(document).ready(function () {
    $(window).resize(function() {
        if ($(window).width() < 600) {
            $('body').css('font-size', '2.8vw' );
        } else if ($(window).width() >= 600 && $(window).width() < 750) {
            $('body').css('font-size', '2.4vw');
        } 
         // and so on... (according to our needs)
        } else if ($(window).width() >= 1200) {
            $('body').css('font-size', '1.2vw');
        }
    }); 
  });

It worked for me well !

The extra line of appearance: none was key to me.

1) Open your terminal and type

npm install -g http-server

2) Go to the root folder that you want to serve you files and type:

http-server ./

3) Read the output of the terminal, something kinda http://localhost:8080 will appear.

Everything on there will be allowed to be got. Example:

background: url('http://localhost:8080/waw.png');

Try this:

SELECT Locations.Name, Schools.Name
FROM Locations
INNER JOIN School_Locations ON School_Locations.Locations_Id = Locations.Id
INNER JOIN Schools ON School.Id = Schools_Locations.School_Id
WHERE Locations.Type = "coun"

You can join Locations to School_Locations and then School_Locations to School. This forms a set of all related Locations and Schools, which you can then widdle down using the WHERE clause to those whose Location is of type "coun."

SQL SERVER 2005:

print upper('hello');
print lower('HELLO');

Using from your_file import * should fix your problems. It defines everything so that it is globally available (with the exception of local variables in the imports of course).

for example:

##test.py:

from pytest import *

print hello_world

and:

##pytest.py

hello_world="hello world!"

Note the "" at the beginning and at the end!

The SUBTOTAL function can be used if you want to get the count respecting any filters you use on the page.

=SUBTOTAL(103, A1:A200)

will help you get count of non-empty rows, respecting filters.

103 - is similar to COUNTA, but ignores empty rows and also respects filters.

Reference : SUBTOTAL function

This is a solution that uses gawk. It's something I find I need to use often so I created a function for it

function regex1 { gawk 'match($0,/'$1'/, ary) {print ary['${2:-'1'}']}'; }

to use just do

$ echo 'hello world' | regex1 'hello\s(.*)'
world

Yet there is no exact cross browser predefined way to do it , you can achieve it by controlling the scope of variables as showed on other answers.

But i will suggest to use name space to distinguish from other variables. this will reduce the chance of collision to minimum from other variables.

Proper namespacing like

var iw_constant={
     name:'sudhanshu',
     age:'23'
     //all varibale come like this
}

so while using it will be iw_constant.name or iw_constant.age

You can also block adding any new key or changing any key inside iw_constant using Object.freeze method. However its not supported on legacy browser.

ex:

Object.freeze(iw_constant);

For older browser you can use polyfill for freeze method.

If you are ok with calling function following is best cross browser way to define constant. Scoping your object within a self executing function and returning a get function for your constants ex:

var iw_constant= (function(){
       var allConstant={
             name:'sudhanshu',
             age:'23'
             //all varibale come like this

       };

       return function(key){
          allConstant[key];
       }
    };

//to get the value use iw_constant('name') or iw_constant('age')

** In both example you have to be very careful on name spacing so that your object or function shouldn't be replaced through other library.(If object or function itself wil be replaced your whole constant will go)

Some may suggest using Javascript to capture the users' actions, like right-clicking the mouse or the Ctrl+C / Ctrl+V key combinations and then stopping the operation. But this is obviously not the best or simplest solution. The solution is integrated in the input field properties itself together with some event capturing using Javascript.

In order to disabled the browsers' autocomplete, simply add the attribute to the input field. It should look something like this:

<input type="text" autocomplete="off">

And if you want to deny Copy and Paste for that field, simply add the Javascript event capturing calls oncopy, onpaste, and oncut and make them return false, like so:

<input type="text" oncopy="return false;" onpaste="return false;" oncut="return false;">

The next step is using onselectstart to deny the input field's content selection from the user, but be warned: this only works for Internet Explorer. The rest of the above work great on all the major browsers: Internet Explorer, Mozilla Firefox, Apple Safari (on Windows OS, at least) and Google Chrome.

I realize this is an old question but I found it in a Google search so I'm going to go ahead and answer just in case someone else runs across this. I'm on a Mac and had the same issue, but solved it by using HomeBrew. Once you've got it installed, you can just run this command:

brew install php56-pdo-pgsql

And replace the 56 with whatever version of PHP you're using without the decimal point.

I just ran into this. As mentioned in this answer, using mode: "no-cors" will give you an opaque response, which doesn't seem to return data in the body.

opaque: Response for “no-cors” request to cross-origin resource. Severely restricted.

In my case I was using Express. After I installed cors for Express and configured it and removed mode: "no-cors", I was returned a promise. The response data will be in the promise, e.g.

fetch('http://example.com/api/node', {
  // mode: 'no-cors',
  method: 'GET',
  headers: {
    Accept: 'application/json',
  },
},
).then(response => {
  if (response.ok) {
    response.json().then(json => {
      console.log(json);
    });
  }
});

You can make master point at 1258f0d0aae this way:

git checkout master
git reset --hard 1258f0d0aae

But you have to be careful about doing this. It may well rewrite the history of that branch. That would create problems if you have published it and other people are working on the branch.

Also, the git reset --hard command will throw away any uncommitted changes (i.e. those just in your working tree or the index).

You can also force an update to a branch with:

git branch -f master 1258f0d0aae

... but git won't let you do that if you're on master at the time.

in my case i had to add the sources in the Visual studio Options->NugetPAckageManager->sources and then restart the visual studio command prompt

Is there something special with that directory or are you really just asking how to copy directories?

Copy recursively via CLI:

cp -R <sourcedir> <destdir>

If you're only seeing the files under the sourcedir being copied (instead of sourcedir as well), that's happening because you kept the trailing slash for sourcedir:

cp -R <sourcedir>/ <destdir>

The above only copies the files and their directories inside of sourcedir. Typically, you want to include the directory you're copying, so drop the trailing slash:

cp -R <sourcedir> <destdir>

When your activity is recreated after it was previously destroyed, you can recover your saved state from the Bundle that the system passes your activity. Both the onCreate() and onRestoreInstanceState() callback methods receive the same Bundle that contains the instance state information.

Because the onCreate() method is called whether the system is creating a new instance of your activity or recreating a previous one, you must check whether the state Bundle is null before you attempt to read it. If it is null, then the system is creating a new instance of the activity, instead of restoring a previous one that was destroyed.

static final String STATE_USER = "user";
private String mUser;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    // Check whether we're recreating a previously destroyed instance
    if (savedInstanceState != null) {
        // Restore value of members from saved state
        mUser = savedInstanceState.getString(STATE_USER);
    } else {
        // Probably initialize members with default values for a new instance
        mUser = "NewUser";
    }
}

@Override
public void onSaveInstanceState(Bundle savedInstanceState) {
    savedInstanceState.putString(STATE_USER, mUser);
    // Always call the superclass so it can save the view hierarchy state
    super.onSaveInstanceState(savedInstanceState);
}

The following command worked for me using the command prompt (As an Administrator) in Windows:

mysqlcheck -u root -p -A --auto-repair

Run mysqlcheck with the root user, prompt for a password, check all databases, and auto-repair any corrupted tables.

I have not seen any option in Microsoft SQL Server Management Studio 2012 to-date that will do that.

I am sure you can write something in T-SQL given the time.

If you're using Python 2.x, try installing a urllib2 opener. That should print out your headers, although you may have to combine that with other openers you're using to hit the HTTPS.

urllib2.urlopen(url)

The following works how you want it, but it is not ideal.

        spinner = (Spinner) findViewById(R.id.spin);
        ArrayAdapter<String> ad = new ArrayAdapter<String>(this, android.R.layout.simple_dropdown_item_1line, vals);
        spinner.setAdapter(ad);
        Log.i("", "" + spinner.getChildCount());

                int b = spinner.getChildCount();
                System.out.println("Count =" + a);
                System.out.println("ChildCount =" + b);
                for (int i = 0; i < b; i++) {
                    View v = spinner.getChildAt(i);
                    if (v == null) {
                        System.out.println("View not found");
                    } else {
                        v.setOnClickListener(new View.OnClickListener() {

                            @Override
                            public void onClick(View v) {
                                        Log.i("","click");
                                        }
                        });
                    }
                }
            }
        }, 500);
    }
}

Let me know exactly how you need the spinner to behave, and we can work out a better solution.

function addClass(ele, cls) {
    if (!hasClass(ele, cls)) ele.className += " " + cls;
}
function removeClass(ele, cls) {
    if (hasClass(ele, cls)) {
        var reg = new RegExp('(\\s|^)' + cls + '(\\s|$)');
        ele.className = ele.className.replace(reg, ' ');
    }
}

So, for example, if I want onclick to add some class to the button I can use this:

<script type="text/javascript">
    function changeClass(btn, cls) {
        if(!hasClass(btn, cls)) {
            addClass(btn, cls);
        }
    }
</script>
...
<button onclick="changeClass(this, "someClass")">My Button</button>

By now for sure it would just be better to use jQuery.

You should use Console.ReadLine() if you want to read some input from the console.

To see your code running in Console:

In Solution Explorer (View - Solution Explorer from the menu), right click on your project, select Open Folder in File Explorer, to find where your project path is.

Supposedly the path is C:\code\myProj .

Open the Command Prompt app in Windows.

Change to your folder path. cd C:\code\myProj

Change to the debug folder, where you should find your program executable. cd bin\debug

Run your program executable, it should end in .exe extension.

Example:

myproj.exe

You should see what you output in Console.Out.WriteLine() .

Well, I believe it's an "Old but Gold" question. The answer is: "It depends!". The performances are such a delicate subject that it would be too much silly to say: "Never use subqueries, always join". In the following links, you'll find some basic best practices that I have found to be very helpful:

• Optimizing Subqueries
• Optimizing Subqueries with Semijoin Transformations
• Rewriting Subqueries as Joins

I have a table with 50000 elements, the result i was looking for was 739 elements.

My query at first was this:

SELECT  p.id,
    p.fixedId,
    p.azienda_id,
    p.categoria_id,
    p.linea,
    p.tipo,
    p.nome
FROM prodotto p
WHERE p.azienda_id = 2699 AND p.anno = (
    SELECT MAX(p2.anno) 
    FROM prodotto p2 
    WHERE p2.fixedId = p.fixedId 
)

and it took 7.9s to execute.

My query at last is this:

SELECT  p.id,
    p.fixedId,
    p.azienda_id,
    p.categoria_id,
    p.linea,
    p.tipo,
    p.nome
FROM prodotto p
WHERE p.azienda_id = 2699 AND (p.fixedId, p.anno) IN
(
    SELECT p2.fixedId, MAX(p2.anno)
    FROM prodotto p2
    WHERE p.azienda_id = p2.azienda_id
    GROUP BY p2.fixedId
)

and it took 0.0256s

Good SQL, good.

The font sizes in your question are an example of what ratio each header should be in comparison to each other, rather than what size they should be themselves (in pixels).

So in response to your question "Is there a 'best practice' for these for mobile phones? - say iphone screen size?", yes there probably is - but you might find what someone says is "best practice" does not work for your layout.

However, to help get you on the right track, this article about building responsive layouts provides a good example of how to calculate the base font-size in pixels in relation to device screen sizes.

The suggested font-sizes for screen resolutions suggested from that article are as follows:

@media (min-width: 858px) {
    html {
        font-size: 12px;
    }
}

@media (min-width: 780px) {
    html {
        font-size: 11px;
    }
}

@media (min-width: 702px) {
    html {
        font-size: 10px;
    }
}

@media (min-width: 724px) {
    html {
        font-size: 9px;
    }
}

@media (max-width: 623px) {
    html {
        font-size: 8px;
    }
}

You can Use This code.

var checkbox = document.getElementById("dlCheckAll4Delete");
checkbox.addEventListener("click", function (event) {
  let checkboxes = document.querySelectorAll(".dlMultiDelete");
  checkboxes.forEach(function (ele) {
    ele.checked = !!checkbox.checked;
  });
});

I think this problem occurs when you try to access your web driver object after

1) a window has closed and you haven't yet switched to the parent

2) you switched to a window that wasn't quite ready and has been updated since you switched

waiting for the windowhandles.count to be what you're expecting doesn't take into account the page content nor does document.ready. I'm still searching for a solution to this problem

dist = sqrt( (x2 - x1)**2 + (y2 - y1)**2 )

As others have pointed out, you can also use the equivalent built-in math.hypot():

dist = math.hypot(x2 - x1, y2 - y1)

Required here

<div class="outer">Outer Text <div class="inner"> Inner Text</div> </div>

added by

$(document).ready(function(){ $('.inner').prepend('<div class="middle">New Text Middle</div>'); });

To anyone still having this issue (Error: Working copy '{DIR}' locked.), I have your solution:

I found that when one of TortoiseSVN windows crash, it leaves a TSVNCache.exe that still has a few handles to your working copy and that is causing the Lock issues you are seeing (and also prevents Clean Up from doing it's job).

So to resolve this:

Either

1a) Use Process Explorer or similar to delete the handles owned by TSVNCache.exe

1b) ..Or even easier, just use Task Manager to kill TSVNCache.exe

Then

2) Right click -> TortoiseSVN -> Clean up. Only "Clean up working copy status" needs to be checked.

From there, happy updating/committing. You can reproduce Lock behavior by doing SVN Update and then quickly killing it's TortoiseProc.exe process before Update finishes.

Alternative way with just one class while keeping your styles in a CSS file, which even works in IE7:

<table class="mytable">
    <tr>
        <th>From</th>
        <th>Subject</th>
        <th>Date</th>
    </tr>
</table>
<style>
    .mytable td, .mytable th { width:15%; }
    .mytable td + td, .mytable th + th { width:70%; }
    .mytable td + td + td, .mytable th + th + th { width:15%; }
</style>

More recently, you can also use the nth-child() selector from CSS3 (IE9+), where you'd just put the nr. of the respective column into the parenthesis instead of stringing them together with the adjacent selector. Like this, for example:

<style>
    .mytable tr > *:nth-child(1) { width:15%; }
    .mytable tr > *:nth-child(2) { width:70%; }
    .mytable tr > *:nth-child(3) { width:15%; }
</style>

All previous answers are great , i just thought to give an insight on why a structure can't contain an instance of its own type (not a reference).

its very important to note that structures are 'value' types i.e they contain the actual value, so when you declare a structure the compiler has to decide how much memory to allocate to an instance of it, so it goes through all its members and adds up their memory to figure out the over all memory of the struct, but if the compiler found an instance of the same struct inside then this is a paradox (i.e in order to know how much memory struct A takes you have to decide how much memory struct A takes !).

But reference types are different, if a struct 'A' contains a 'reference' to an instance of its own type, although we don't know yet how much memory is allocated to it, we know how much memory is allocated to a memory address (i.e the reference).

Some time some javascript functions does not work on some specific browser. I would suggest you to start using JQuery, which gives you normalized JS, taking care of different browser requirement

$('#btn1').each(function(){
    this.disabled = false;
});

Here is a somewhat kludgy way to do it that works with GO-batches, by using a "global" variable.

if object_id('tempdb..#vars') is not null
begin
  drop table #vars
end

create table #vars (continueScript bit)
set nocount on
  insert #vars values (1)
set nocount off

-- Start of first batch
if ((select continueScript from #vars)=1) begin

  print '1'

  -- Conditionally terminate entire script
  if (1=1) begin
    set nocount on
      update #vars set continueScript=0
    set nocount off
    return
  end

end
go

-- Start of second batch
if ((select continueScript from #vars)=1) begin

  print '2'

end
go

And here is the same idea used with a transaction and a try/catch block for each GO-batch. You can try to change the various conditions and/or let it generate an error (divide by 0, see comments) to test how it behaves:

if object_id('tempdb..#vars') is not null
begin
  drop table #vars
end

create table #vars (continueScript bit)
set nocount on
  insert #vars values (1)
set nocount off

begin transaction;
  -- Batch 1 starts here
  if ((select continueScript from #vars)=1) begin
    begin try 
      print 'batch 1 starts'

      if (1=0) begin
        print 'Script is terminating because of special condition 1.'
        set nocount on
          update #vars set continueScript=0
        set nocount off
        return
      end

      print 'batch 1 in the middle of its progress'

      if (1=0) begin
        print 'Script is terminating because of special condition 2.'
        set nocount on
          update #vars set continueScript=0
        set nocount off
        return
      end

      set nocount on
        -- use 1/0 to generate an exception here
        select 1/1 as test
      set nocount off

    end try
    begin catch
      set nocount on
        select 
          error_number() as errornumber
          ,error_severity() as errorseverity
          ,error_state() as errorstate
          ,error_procedure() as errorprocedure
          ,error_line() as errorline
          ,error_message() as errormessage;
        print 'Script is terminating because of error.'
        update #vars set continueScript=0
      set nocount off
      return
    end catch;

  end
  go

  -- Batch 2 starts here
  if ((select continueScript from #vars)=1) begin

    begin try 
      print 'batch 2 starts'

      if (1=0) begin
        print 'Script is terminating because of special condition 1.'
        set nocount on
          update #vars set continueScript=0
        set nocount off
        return
      end

      print 'batch 2 in the middle of its progress'

      if (1=0) begin
        print 'Script is terminating because of special condition 2.'
        set nocount on
          update #vars set continueScript=0
        set nocount off
        return
      end

      set nocount on
        -- use 1/0 to generate an exception here
        select 1/1 as test
      set nocount off

    end try
    begin catch
      set nocount on
        select 
          error_number() as errornumber

          ,error_line() as errorline

        print 'Script is terminating because of error.'
        update #vars set continueScript=0

The value for an annotation must be a compile time constant, so there is no simple way of doing what you are trying to do.

See also here: How to supply value to an annotation from a Constant java

It is possible to use some compile time tools (ant, maven?) to config it if the value is known before you try to run the program.

easy if its pdf or img use

return (in_Array($file['content-type'], ['image/jpg', 'application/pdf']));

Well the problem simply-put is that the SUM(TIME) for a specific SSN on your query is a single value, so it's objecting to MAX as it makes no sense (The maximum of a single value is meaningless).

Not sure what SQL database server you're using but I suspect you want a query more like this (Written with a MSSQL background - may need some translating to the sql server you're using):

SELECT TOP 1 SSN, SUM(TIME)
FROM downloads
GROUP BY SSN
ORDER BY 2 DESC

This will give you the SSN with the highest total time and the total time for it.

Edit - If you have multiple with an equal time and want them all you would use:

SELECT
SSN, SUM(TIME)
FROM downloads
GROUP BY SSN
HAVING SUM(TIME)=(SELECT MAX(SUM(TIME)) FROM downloads GROUP BY SSN))

In my case, I got this error when there are 2 or more libraries conflict (same library but different versions). Check your app build.gradle in dependencies block.

The code that you looked at is not ideal. You should either:

1. Catch the exception and handle it; in which case the throws is unnecesary.

2. Remove the try/catch; in which case the Exception will be handled by a calling method.

3. Catch the exception, possibly perform some action and then rethrow the exception (not just the message)

Your query fails due to operator precedence. AND binds before OR!
You need a pair of parentheses, which is not a matter of "clarity", but pure logic necessity.

SELECT *
FROM   tbl_name
WHERE  other_condition = bar
AND    another_condition = foo
AND   (id_field IN ('value1', 'value2', 'value3') OR id_field IS NULL);

The added parentheses prevent AND binding before OR. If there were no other WHERE conditions (no AND) you would not need additional parentheses. The accepted answer is misleading in this respect.

REGEXP_LIKE(column, '^[[:digit:]]+$')

returns TRUE if column holds only numeric characters

SIGABRT means in general that there is an uncaught exception. There should be more information on the console.

If I understand correctly, you assumed that -v is the "print version" command. Check the documentation, that is not the case -- instead ant -v is running ant build in verbose mode. So ant is trying to perform your build, based on the build.xml file, which is obviously not there.

To answer your question explicitly: there is probably nothing wrong with both the system nor ant installation.

XPath 1.0 doesn't handle regex natively, you could try something like

//*[starts-with(@id, 'sometext') and ends-with(@id, '_text')]

(as pointed out by paul t, //*[boolean(number(substring-before(substring-after(@id, "sometext"), "_text")))] could be used to perform the same check your original regex does, if you need to check for middle digits as well)

In XPath 2.0, try

//*[matches(@id, 'sometext\d+_text')]

Here is the solution for Rest API

class Program
{
    static void Main(string[] args)
    {
        BaseClient clientbase = new BaseClient("https://website.com/api/v2/", "username", "password");
        BaseResponse response = new BaseResponse();
        BaseResponse response = clientbase.GetCallV2Async("Candidate").Result;
    }


    public async Task<BaseResponse> GetCallAsync(string endpoint)
    {
        try
        {
            HttpResponseMessage response = await client.GetAsync(endpoint + "/").ConfigureAwait(false);
            if (response.IsSuccessStatusCode)
            {
                baseresponse.ResponseMessage = await response.Content.ReadAsStringAsync();
                baseresponse.StatusCode = (int)response.StatusCode;
            }
            else
            {
                baseresponse.ResponseMessage = await response.Content.ReadAsStringAsync();
                baseresponse.StatusCode = (int)response.StatusCode;
            }
            return baseresponse;
        }
        catch (Exception ex)
        {
            baseresponse.StatusCode = 0;
            baseresponse.ResponseMessage = (ex.Message ?? ex.InnerException.ToString());
        }
        return baseresponse;
    }
}


public class BaseResponse
{
    public int StatusCode { get; set; }
    public string ResponseMessage { get; set; }
}

public class BaseClient
{
    readonly HttpClient client;
    readonly BaseResponse baseresponse;

    public BaseClient(string baseAddress, string username, string password)
    {
        HttpClientHandler handler = new HttpClientHandler()
        {
            Proxy = new WebProxy("http://127.0.0.1:8888"),
            UseProxy = false,
        };

        client = new HttpClient(handler);
        client.BaseAddress = new Uri(baseAddress);
        client.DefaultRequestHeaders.Accept.Clear();
        client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
        var byteArray = Encoding.ASCII.GetBytes(username + ":" + password);

        client.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Basic", Convert.ToBase64String(byteArray));

        baseresponse = new BaseResponse();

    }
}

user:Array[]=[1,2,3];
if(this.user.length)
{
    console.log("user has contents");
}
else{
    console.log("user is empty");
}

In such scenario last used key is usually known so it can be used for accessing last value (inserted with the one):

class PostIndexData {
    String _office_name;
    Boolean _isGov;
    public PostIndexData(String name, Boolean gov) {
        _office_name = name;
        _isGov = gov;
    }
}
//-----------------------
class KgpData {
    String _postIndex;
    PostIndexData _postIndexData;
    public KgpData(String postIndex, PostIndexData postIndexData) {
        _postIndex = postIndex;
        _postIndexData = postIndexData;;
    }
}

public class Office2ASMPro {
    private HashMap<String,PostIndexData> _postIndexMap = new HashMap<>();
    private HashMap<String,KgpData> _kgpMap = new HashMap<>();
...
private void addOffice(String kgp, String postIndex, String officeName, Boolean gov) {
            if (_postIndexMap.get(postIndex) == null) {
                _postIndexMap.put(postIndex, new PostIndexData(officeName, gov));
            }
            _kgpMap.put( kgp, new KgpData(postIndex, _postIndexMap.get(postIndex)) );
        }

A crazy regex approach

"xxx_456".match(/...$/)[0] //456

Even there exist an accepted answer, I'll like to demonstrate the following (with Python 2.7.2 and Numpy 1.6.0 on Vista):

In []: x= rand(1e5)
In []: %timeit isnan(x.min())
10000 loops, best of 3: 200 us per loop
In []: %timeit isnan(x.sum())
10000 loops, best of 3: 169 us per loop
In []: %timeit isnan(dot(x, x))
10000 loops, best of 3: 134 us per loop

In []: x[5e4]= NaN
In []: %timeit isnan(x.min())
100 loops, best of 3: 4.47 ms per loop
In []: %timeit isnan(x.sum())
100 loops, best of 3: 6.44 ms per loop
In []: %timeit isnan(dot(x, x))
10000 loops, best of 3: 138 us per loop

Thus, the really efficient way might be heavily dependent on the operating system. Anyway dot(.) based seems to be the most stable one.

If you are facing problem with pip3 install pyqt5 then try pip3 install pyqt5==5.12.0
This solved the problem for me

You can include a .js file which has the script to set the

window.location.href = url;

Where url would be the url you wish to load.
