If you have access to the NgModelController (you can only get access to it from a directive) then you can call

ngModel.$setViewValue("your new view value");
// or to keep the view value the same and just change it to dirty
ngModel.$setViewValue(ngModel.$viewValue);

You're looking for Action<T>, which takes a parameter.

There is a problem with setting the tint color on the view after presenting; even if you do it in the completion block of presentViewController:animated:completion:, it causes a flicker effect on the color of the button titles. This is sloppy, unprofessional and completely unacceptable.

Other solutions presented depend on the view hierarchy remaining static, something that Apple is loathe to do. Expect those solutions to fail in future releases of iOS.

The one sure-fire way to solve this problem and to do it everywhere, is via adding a category to UIAlertController and swizzling the viewWillAppear.

The header:

//
//  UIAlertController+iOS9TintFix.h
//
//  Created by Flor, Daniel J on 11/2/15.
//

#import <UIKit/UIKit.h>

@interface UIAlertController (iOS9TintFix)

+ (void)tintFix;

- (void)swizzledViewWillAppear:(BOOL)animated;

@end

The implementation:

//
//  UIAlertController+iOS9TintFix.m
//
//  Created by Flor, Daniel J on 11/2/15.
//

#import "UIAlertController+iOS9TintFix.h"
#import <objc/runtime.h>

@implementation UIAlertController (iOS9TintFix)

+ (void)tintFix {
    static dispatch_once_t onceToken;
    dispatch_once(&onceToken, ^{
        Method method  = class_getInstanceMethod(self, @selector(viewWillAppear:));
        Method swizzle = class_getInstanceMethod(self, @selector(swizzledViewWillAppear:));
        method_exchangeImplementations(method, swizzle);});
}

- (void)swizzledViewWillAppear:(BOOL)animated {
    [self swizzledViewWillAppear:animated];
    for (UIView *view in self.view.subviews) {
        if (view.tintColor == self.view.tintColor) {
            //only do those that match the main view, so we don't strip the red-tint from destructive buttons.
            self.view.tintColor = [UIColor colorWithRed:0.0 green:122.0/255.0 blue:1.0 alpha:1.0];
            [view setNeedsDisplay];
        }
    }
}

@end

Add a .pch (precompiled header) to your project and include the category:

#import "UIAlertController+iOS9TintFix.h"

Make sure you register your pch in the project properly, and it will include the category methods in every class that uses the UIAlertController.

Then, in your app delegates didFinishLaunchingWithOptions method, import your category and call

[UIAlertController tintFix];

and it will automatically propagate to every single instance of UIAlertController within your app, whether launched by your code or anyone else's.

This solution works for both iOS 8.X and iOS 9.X and lacks the flicker of the tint change post-presentation approach. It is also completely agnostic with respect to the view hierarchy of the sub-views of the UIAlertController.

Happy hacking!

Got the answer :

This is an updated version to the answer provided by @PodTech.io

This version has all of the vbs code correctly escaped in the batch file. It's also created into a sub-routine, which can be called with a single line from anywhere in your batch script:

call :ZipUp "C:\Some\Path" "C:\Archive.zip"


:: === SubRoutines:

:ZipUp
::Arguments: Source_folder, destination_zip

Sorry, not enough rep to add a comment, but from zmbq's answer:

Anyway, to see if a cookie exists, you can check Cookies.Get(string), this will not modify the cookie collection.

is maybe not fully correct, as Cookies.Get(string) will actually create a cookie with that name, if it does not already exist. However, as he said, you need to be looking at Request.Cookies, not Response.Cookies So, something like:

bool cookieExists = HttpContext.Current.Request.Cookies["cookie_name"] != null;

For Python 3xx:

import time
for i in range(10):
    time.sleep(0.2) 
    print ("\r Loading... {}".format(i)+str(i), end="")

var uniqueColors = (from dbo in database.MainTable 
                    where dbo.Property == true
                    select dbo.Color.Name).Distinct();

Instead of using any 3rd party library for query operations, I would rather suggest writing queries on your own. Because using any other 3rd party packages would take away the main advantage of using dapper i.e. flexibility to write queries.

Now, there is a problem with writing Insert or Update query for the entire object. For this, one can simply create helpers like below:

InsertQueryBuilder:

 public static string InsertQueryBuilder(IEnumerable < string > fields) {


  StringBuilder columns = new StringBuilder();
  StringBuilder values = new StringBuilder();


  foreach(string columnName in fields) {
   columns.Append($ "{columnName}, ");
   values.Append($ "@{columnName}, ");

  }
  string insertQuery = $ "({ columns.ToString().TrimEnd(',', ' ')}) VALUES ({ values.ToString().TrimEnd(',', ' ')}) ";

  return insertQuery;
 }

Now, by simply passing the name of the columns to insert, the whole query will be created automatically, like below:

List < string > columns = new List < string > {
 "UserName",
 "City"
}
//QueryBuilder is the class having the InsertQueryBuilder()
string insertQueryValues = QueryBuilderUtil.InsertQueryBuilder(columns);

string insertQuery = $ "INSERT INTO UserDetails {insertQueryValues} RETURNING UserId";

Guid insertedId = await _connection.ExecuteScalarAsync < Guid > (insertQuery, userObj);

You can also modify the function to return the entire INSERT statement by passing the TableName parameter.

Make sure that the Class property names match with the field names in the database. Then only you can pass the entire obj (like userObj in our case) and values will be mapped automatically.

In the same way, you can have the helper function for UPDATE query as well:

  public static string UpdateQueryBuilder(List < string > fields) {
   StringBuilder updateQueryBuilder = new StringBuilder();

   foreach(string columnName in fields) {
    updateQueryBuilder.AppendFormat("{0}=@{0}, ", columnName);
   }
   return updateQueryBuilder.ToString().TrimEnd(',', ' ');
  }

And use it like:

List < string > columns = new List < string > {
 "UserName",
 "City"
}
//QueryBuilder is the class having the UpdateQueryBuilder()
string updateQueryValues = QueryBuilderUtil.UpdateQueryBuilder(columns);

string updateQuery =  $"UPDATE UserDetails SET {updateQueryValues} WHERE UserId=@UserId";

await _connection.ExecuteAsync(updateQuery, userObj);

Though in these helper functions also, you need to pass the name of the fields you want to insert or update but at least you have full control over the query and can also include different WHERE clauses as and when required.

Through this helper functions, you will save the following lines of code:

For Insert Query:

 $ "INSERT INTO UserDetails (UserName,City) VALUES (@UserName,@City) RETURNING UserId";

For Update Query:

$"UPDATE UserDetails SET UserName=@UserName, City=@City WHERE UserId=@UserId";

There seems to be a difference of few lines of code, but when it comes to performing insert or update operation with a table having more than 10 fields, one can feel the difference.

You can use the nameof operator to pass the field name in the function to avoid typos

Instead of:

List < string > columns = new List < string > {
 "UserName",
 "City"
}

You can write:

List < string > columns = new List < string > {
nameof(UserEntity.UserName),
nameof(UserEntity.City),
}

Try to use ES6 syntax of set timeout. Normal javascript setTimeout() won't work in react js

setTimeout(
      () => this.setState({ position: 100 }), 
      5000
    );

Use sqlcmd instead of osql if it's a 2005 database

You haven't specified what the query should return if more than one document is added at the same time, so this query assumes you want all of them returned:

SELECT t.ID,
       t.USER_ID,
       t.DATE_ADDED,
       t.DATE_VIEWED,
       t.DOCUMENT_ID,
       t.URL,
       t.DOCUMENT_TITLE,
       t.DOCUMENT_DATE
FROM (
  SELECT test_table.*,
         RANK()
         OVER (ORDER BY DOCUMENT_DATE DESC) AS the_rank
  FROM   test_table
  WHERE  user_id = value
  )
WHERE the_rank = 1;

This query will only make one pass through the data.

I liked the solution in the earlier post.

I made a mini-class, called it class AlphabeticalHash. It also has a method called ap, which accepts one argument, a Hash, as input: ap variable. Akin to pp (pp variable)

But it will (try and) print in alphabetical list (its keys). Dunno if anyone else wants to use this, it's available as a gem, you can install it as such: gem install alphabetical_hash

For me, this is simple enough. If others need more functionality, let me know, I'll include it into the gem.

EDIT: Credit goes to Peter, who gave me the idea. :)

In C++ the stack memory is where local variables get stored/constructed. The stack is also used to hold parameters passed to functions.

The stack is very much like the std::stack class: you push parameters onto it and then call a function. The function then knows that the parameters it expects can be found on the end of the stack. Likewise, the function can push locals onto the stack and pop them off it before returning from the function. (caveat - compiler optimizations and calling conventions all mean things aren't this simple)

The stack is really best understood from a low level and I'd recommend Art of Assembly - Passing Parameters on the Stack. Rarely, if ever, would you consider any sort of manual stack manipulation from C++.

Generally speaking, the stack is preferred as it is usually in the CPU cache, so operations involving objects stored on it tend to be faster. However the stack is a limited resource, and shouldn't be used for anything large. Running out of stack memory is called a Stack buffer overflow. It's a serious thing to encounter, but you really shouldn't come across one unless you have a crazy recursive function or something similar.

Heap memory is much as rskar says. In general, C++ objects allocated with new, or blocks of memory allocated with the likes of malloc end up on the heap. Heap memory almost always must be manually freed, though you should really use a smart pointer class or similar to avoid needing to remember to do so. Running out of heap memory can (will?) result in a std::bad_alloc.

For anyone still having the problem. You could use official Microsoft SMO

https://docs.microsoft.com/en-us/sql/relational-databases/server-management-objects-smo/overview-smo?view=sql-server-2017

using (var connection = new SqlConnection(connectionString))
{
  var server = new Server(new ServerConnection(connection));
  server.ConnectionContext.ExecuteNonQuery(sql);
}

I got the same error from IIS under windows 7. To fix this error i had to add full control permissions to IUSR account for sqlite database file. You don't need to change permissions if you use sqlite under webmatrix instead of IIS.

Compiler:

It will read source file which may be of type .c or .cpp etc and translates that to .o file called as object file.

Linker:

It combines the several .o files which may be generated for multiple source files into an executable file (ELF format in GCC). There are two type of linking:

• static linking
• dynamic linking

Loader:

A program which loads the executable file to the primary memory of the machine.

Late answer, but many views. As APIs < 11 ain't dead yet, for those interested here is a trick.

Let your container have the desired color (may be transparent). Then give your buttons a selector with default transparent color, and some color when pressed. That way you'll have a transparent button, but will change color when pressed (like holo's). You can also add some animation (like holo's). The selector should be something like this:

res/drawable/selector_transparent_button.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" 
          android:exitFadeDuration="@android:integer/config_shortAnimTime">
     <item android:state_pressed="true"
         android:drawable="@color/blue" />

   <item android:drawable="@color/transparent" />
</selector>

And the button should have android:background="@drawable/selector_transparent_button"

PS: let you container have the dividers (android:divider='@android:drawable/... for API < 11)

PS [Newbies]: you should define those colors in values/colors.xml

1. You can use a struct to read write into a file. You do not need to cast it as a `char*. Struct size will also be preserved. (This point is not closest to the topic but guess it: behaving on hard memory is often similar to RAM one.)

2. To move (to & from) a single string field you must use strncpy and a transient string buffer '\0' terminating. Somewhere you must remember the length of the record string field.

3. To move other fields you can use the dot notation, ex.: NodeB->one=intvar; floatvar2=(NodeA->insidebisnode_subvar).myfl;

   struct mynode {
       int one;
       int two;
       char txt3[3];
       struct{char txt2[6];}txt2fi;
       struct insidenode{
           char txt[8];
           long int myl;
           void * mypointer;
           size_t myst;
           long long myll;
            } insidenode_subvar;
       struct insidebisnode{
           float myfl;
            } insidebisnode_subvar;
   } mynode_subvar;
   
   typedef struct mynode* Node;
   
   ...(main)
   Node NodeA=malloc...
   Node NodeB=malloc...
   

4. You can embed each string into a structs that fit it, to evade point-2 and behave like Cobol: NodeB->txt2fi=NodeA->txt2fi ...but you will still need of a transient string plus one strncpy as mentioned at point-2 for scanf, printf otherwise an operator longer input (shorter), would have not be truncated (by spaces padded).

5. (NodeB->insidenode_subvar).mypointer=(NodeA->insidenode_subvar).mypointer will create a pointer alias.
6. NodeB.txt3=NodeA.txt3 causes the compiler to reject: error: incompatible types when assigning to type ‘char[3]’ from type ‘char *’

7. point-4 works only because NodeB->txt2fi & NodeA->txt2fi belong to the same typedef !!

   A correct and simple answer to this topic I found at In C, why can't I assign a string to a char array after it's declared? "Arrays (also of chars) are second-class citizens in C"!!!

If elem.find() is not working for you, check that you are including JQuery script before angular script....

Use this form:

=(B0+4)/$A$0

The $ tells excel not to adjust that address while pasting the formula into new cells.

Since you are dragging across rows, you really only need to freeze the row part:

=(B0+4)/A$0

Keyboard Shortcuts

Commenters helpfully pointed out that you can toggle relative addressing for a formula in the currently selected cells with these keyboard shortcuts:

• Windows: f4
• Mac: CommandT

require 'json'
out=JSON.parse(input)

This will return a Hash

Here it is how it worked for me, family_id is the primary key with auto increment I am using Laravel7

    public function store(Request $request){
        $family = new Family();
        $family->family_name = $request->get('FamilyName');
        $family->family_no = $request->get('FamilyNo');
        $family->save();
        //family_id is the primary key and auto increment
        return redirect('/family/detail/' .  $family->family_id);
    }

Also in the Model Family file which extends Model, should have the increment set to true otherwise the above $family-->family_id will return empty

    public $incrementing = true;
  

I actually managed to work out what I was doing wrong (and it was my fault).

I'm used to using pre-jQuery Rails, so when I included the Bootstrap JS files I didn't think that including the version of jQuery bundled with them would cause any issues, however when I removed that one JS file everything started working perfectly.

Lesson learnt, triple check which JS files are loaded, see if there's any conflicts.

Well using find is the best option here

just simply use like this

$(".class").click(function(){
        $("this").find('.subclass').css("visibility","visible");
})

and if there are many classes with the same name class its always better to give the class name of parent class like this

$(".parent .class").click(function(){
            $("this").find('.subclass').css("visibility","visible");
    })

Here is a simple approach:

my_string = 'abcdefg'
print(text.find('def'))

Output:

3

I the substring is not there, you will get -1. For example:

my_string = 'abcdefg'
print(text.find('xyz'))

Output:

-1

Sometimes, you might want to throw exception if substring is not there:

my_string = 'abcdefg'
print(text.index('xyz')) # It returns an index only if it's present

Output:

Traceback (most recent call last):

File "test.py", line 6, in print(text.index('xyz'))

ValueError: substring not found

Simple and quick:

Dim lastRow as long
Range("A1").select
lastRow = Cells.Find("*",SearchOrder:=xlByRows,SearchDirection:=xlPrevious).Row

Example use:

cells(lastRow,1)="Ultima Linha, Last Row. Youpi!!!!"

'or 

Range("A" & lastRow).Value = "FIM, THE END"

Style sheets are, effectively, concatenated into a single style sheet in the order in which they appear in the HTML source.

The normal rules for applying rulesets then apply (i.e. by specificity with the last ruleset that defines a given property winning in the event of a tie and !important throwing a spanner into the works)

According to maven website, the last version to support Java 6 is 3.2.5, and 3.3 and up use Java 7. My hunch is that you're using Maven 3.3 or higher, and should either upgrade to Java 7 (and set proper source/target attributes in your pom) or downgrade maven.

The backwards compatible version (IE9+) is

var parent = document.querySelector(selector);
Array.prototype.forEach.call(parent.children, function(child, index){
  // Do stuff
});

The es6 way is

const parent = document.querySelector(selector);
Array.from(parent.children).forEach((child, index) => {
  // Do stuff
});

Gulp uses micromatch under the hood for matching globs, so if you want to exclude any of the .min.js files, you can achieve the same by using an extended globbing feature like this:

src("'js/**/!(*.min).js")

Basically what it says is: grab everything at any level inside of js that doesn't end with *.min.js

HttpContext.Current returns an instance of System.Web.HttpContext, which does not extend System.Web.HttpContextBase. HttpContextBase was added later to address HttpContext being difficult to mock. The two classes are basically unrelated (HttpContextWrapper is used as an adapter between them).

Fortunately, HttpContext itself is fakeable just enough for you do replace the IPrincipal (User) and IIdentity.

The following code runs as expected, even in a console application:

HttpContext.Current = new HttpContext(
    new HttpRequest("", "http://tempuri.org", ""),
    new HttpResponse(new StringWriter())
    );

// User is logged in
HttpContext.Current.User = new GenericPrincipal(
    new GenericIdentity("username"),
    new string[0]
    );

// User is logged out
HttpContext.Current.User = new GenericPrincipal(
    new GenericIdentity(String.Empty),
    new string[0]
    );

If you have a branch different than master, one easy way is to check out that branch, then check out master. Voila, you are back at the tip of master. There's probably smarter ways...

The following command will (1) compare the file of the correct branch, to master (2) interactively ask you which modifications to apply.

git checkout --patch master

You can use the following time conversion within SQL like this:

--Convert Time to Integer (Minutes)
DECLARE @timeNow datetime = '14:47'
SELECT DATEDIFF(mi,CONVERT(datetime,'00:00',108), CONVERT(datetime, RIGHT(CONVERT(varchar, @timeNow, 100),7),108))

--Convert Minutes to Time
DECLARE @intTime int = (SELECT DATEDIFF(mi,CONVERT(datetime,'00:00',108), CONVERT(datetime, RIGHT(CONVERT(varchar, @timeNow, 100),7),108)))
SELECT DATEADD(minute, @intTime, '')

Result: 887 <- Time in minutes and 1900-01-01 14:47:00.000 <-- Minutes to time

You need to install a so-called Instance of MSSQL server on your computer. That is, installing all the needed files and services and database files. By default, there should be no MSSQL Server installed on your machine, assuming that you use a desktop Windows (7,8,10...).

You can start off with Microsoft SQL Server Express, which is a 10GB-limited, free version of MSSQL. It also lacks some other features (Server Agents, AFAIR), but it's good for some experiments.

Download it from the Microsoft Website and go through the installer process by choosing New SQL Server stand-alone installation .. after running the installer.

Click through the steps. For your scenario (it sounds like you mainly want to test some stuff), the default options should suffice.

Just give attention to the step Instance Configuration. There you will set the name of your MSSQL Server Instance. Call it something unique/descriptive like MY_TEST_INSTANCE or the like. Also, choose wisely the Instance root directory. In it, the database files will be placed, so it should be on a drive that has enough space.

Click further through the wizard, and when it's finished, your MSSQL instance will be up and running. It will also run at every boot if you have chosen the default settings for the services.

As soon as it's running in the background, you can connect to it with Management Studio by connecting to .\MY_TEST_INSTANCE, given that that's the name you chose for the instance.

Table variables are just like int or varchar variables.

You don't need to drop them. They have the same scope rules as int or varchar variables

The scope of a variable is the range of Transact-SQL statements that can reference the variable. The scope of a variable lasts from the point it is declared until the end of the batch or stored procedure in which it is declared.

There are two ways I usually do this, both use ssh:

scp -r sourcedir/ [email protected]:/dest/dir/

or, the more robust and faster (in terms of transfer speed) method:

rsync -auv -e ssh --progress sourcedir/ [email protected]:/dest/dir/

Read the man pages for each command if you want more details about how they work.

One point is that it may be easier to do:

$("<div class=foo id=bar style='color:white;bgcolor:blue;font-size:12pt'></div>")

Then to do all of that with jquery calls.

Using command line, you can do this:

AT \\computername time "NET STOP servicename"
AT \\computername time "NET START servicename"

You should be able to use the macros defined in stdint.h. In particular INTPTR_MAX is exactly the value you need.

#include <cstdint>
#if INTPTR_MAX == INT32_MAX
    #define THIS_IS_32_BIT_ENVIRONMENT
#elif INTPTR_MAX == INT64_MAX
    #define THIS_IS_64_BIT_ENVIRONMENT
#else
    #error "Environment not 32 or 64-bit."
#endif

Some (all?) versions of Microsoft's compiler don't come with stdint.h. Not sure why, since it's a standard file. Here's a version you can use: http://msinttypes.googlecode.com/svn/trunk/stdint.h

Just like CommonsWare suggested, make sure you have Gradle 2.2.1+ (the latest is 2.3).

Make sure you upgrade your Android Studio but here are the "plugins" that need to be updated:

Top build.gradle:

Change:

classpath 'com.android.tools.build:gradle:1.1.0-rc1'

To:

classpath 'com.android.tools.build:gradle:1.1.3' // latest 1.5.0

App build.gradle:

Change:

compile 'com.android.support:recyclerview-v7:21.0.0'
compile 'com.android.support:cardview-v7:21.0.0'

To:

compile 'com.android.support:recyclerview-v7:22.0.0' // latest 23.1.1
compile 'com.android.support:cardview-v7:22.0.0' // latest 23.1.1

Gradle: https://gradle.org/downloads

To view the latest plugin releases, view the Bintray Jcenter page directly: https://bintray.com/android/android-tools/com.android.tools.build.gradle/view.

Probably, a better and more functional way is to wrap exceptions and propagate them further in the stream. Take a look at the Try type of Vavr for example.

Example:

interface CheckedFunction<I, O> {
    O apply(I i) throws Exception; }

static <I, O> Function<I, O> unchecked(CheckedFunction<I, O> f) {
    return i -> {
        try {
            return f.apply(i);
        } catch(Exception ex) {

            throw new RuntimeException(ex);
        }
    } }

fileNamesToRead.map(unchecked(file -> Files.readAllLines(file)))

OR

@SuppressWarnings("unchecked")
private static <T, E extends Exception> T throwUnchecked(Exception e) throws E {
    throw (E) e;
}

static <I, O> Function<I, O> unchecked(CheckedFunction<I, O> f) {
    return arg -> {
        try {
            return f.apply(arg);
        } catch(Exception ex) {
            return throwUnchecked(ex);
        }
    };
}

2nd implementation avoids wrapping the exception in a RuntimeException. throwUnchecked works because almost always all generic exceptions are treated as unchecked in java.

Change

document.getElementById('personlist').getElementsByTagName('option')[11].selected = 'selected'

to

document.getElementById('personlist').value=Person_ID;

Focus on second line, so we must to change to:

<IfModule php5_module>
    **<FilesMatch "\.(php|html)$">**
        SetHandler application/x-httpd-php
    </FilesMatch>
    <FilesMatch "\.phps$">
        SetHandler application/x-httpd-php-source
    </FilesMatch>

    PHPINIDir "C:/xampp/php"
</IfModule>

And that is it. Works good!

try this:

In [110]: (df.groupby('Company Name')
   .....:    .agg({'Organisation Name':'count', 'Amount': 'sum'})
   .....:    .reset_index()
   .....:    .rename(columns={'Organisation Name':'Organisation Count'})
   .....: )
Out[110]:
          Company Name   Amount  Organisation Count
0  Vifor Pharma UK Ltd  4207.93                   5

or if you don't want to reset index:

df.groupby('Company Name')['Amount'].agg(['sum','count'])

or

df.groupby('Company Name').agg({'Amount': ['sum','count']})

Demo:

In [98]: df.groupby('Company Name')['Amount'].agg(['sum','count'])
Out[98]:
                         sum  count
Company Name
Vifor Pharma UK Ltd  4207.93      5

In [99]: df.groupby('Company Name').agg({'Amount': ['sum','count']})
Out[99]:
                      Amount
                         sum count
Company Name
Vifor Pharma UK Ltd  4207.93     5

The 2nd call to Enable-Migrations is failing because the Configuration.cs file already exists. If you rename that class and file, you should be able to run that 2nd Enable-Migrations, which will create another Configuration.cs.

You will then need to specify which configuration you want to use when updating the databases.

Update-Database -ConfigurationTypeName MyRenamedConfiguration

Random Number of Random Items from an Array

def random_items(array)
  array.sample(1 + rand(array.count))
end

Examples of possible results:

my_array = ["one", "two", "three"]
my_array.sample(1 + rand(my_array.count))

=> ["two", "three"]
=> ["one", "three", "two"]
=> ["two"]

How about the more readable:

Node *pop (Node **root)
{
    Node *popped = *root;

    if (*root) {
        *root = (*root)->next;
    }

    return (popped);
}

void push (Node **root, Node *new_node)
{
    new_node->next = *root;
    *root = new_node;
}


Node *reverse (Node *root)
{
    Node *new_root = NULL;
    Node *next;

    while ((next = pop(&root))) {
        push (&new_root, next);
    }

    return (new_root);
}

If you want to carry on using CSS3 selectors but need to support older browsers I would suggest using a polyfill such as Selectivizr.js

Using this method you can fill in your div with the image varying ratio of divs and images.

jQuery:

$(window).load(function(){
   $('body').find(.fillme).each(function(){
      var fillmeval = $(this).width()/$(this).height();
      var imgval = $this.children('img').width()/$this.children('img').height();
      var imgClass;
      if(imgval > fillmeval){
          imgClass = "stretchy";
      }else{
          imgClass = "stretchx";
      }
      $(this).children('img').addClass(imgClass);
   });
});

HTML:

<div class="fillme">
   <img src="../images/myimg.jpg" />
</div>

CSS:

.fillme{
  overflow:hidden;
}
.fillme img.stretchx{
  height:auto;
  width:100%;
}
.fillme img.stretchy{
  height:100%;
  width:auto;
}

I created an arrayList from it and I somehow can't find a way to store this information into a JTable.

The DefaultTableModel doesn't support displaying custom Objects stored in an ArrayList. You need to create a custom TableModel.

You can check out the Bean Table Model. It is a reusable class that will use reflection to find all the data in your FootballClub class and display in a JTable.

Or, you can extend the Row Table Model found in the above link to make is easier to create your own custom TableModel by implementing a few methods. The JButtomTableModel.java source code give a complete example of how you can do this.

You can use axis:

> axis(side=1, at=c(0:23))

That is, something like this:

plot(0:23, d, type='b', axes=FALSE)
axis(side=1, at=c(0:23))
axis(side=2, at=seq(0, 600, by=100))
box()

With ES6: This is now part of the language:

function myFunc(a, b = 0) {
   // function body
}

Please keep in mind that ES6 checks the values against undefined and not against truthy-ness (so only real undefined values get the default value - falsy values like null will not default).

With ES5:

function myFunc(a,b) {
  b = b || 0;

  // b will be set either to b or to 0.
}

This works as long as all values you explicitly pass in are truthy. Values that are not truthy as per MiniGod's comment: null, undefined, 0, false, ''

It's pretty common to see JavaScript libraries to do a bunch of checks on optional inputs before the function actually starts.

For Windows or macOS:

Download/Install the Visual Studio IDE (with Unity Tools)

When installing, make sure you include installation of

Game development with Unity

Then using Unity (you can double click one of your C# files), open a new C# project and the Visual Studio IDE should open with your new project structure.

From there, you should be able to see what you are looking for.

For example:

For Linux (suggestion):

Try Monodevelop - Additional Information, it provides code completion/hints.

The following solution is inspired by the SocketUtils implementation of Spring-core (Apache license).

Compared to other solutions using Socket(...) it is pretty fast (testing 1000 TCP ports in less than a second):

public static boolean isTcpPortAvailable(int port) {
    try (ServerSocket serverSocket = new ServerSocket()) {
        // setReuseAddress(false) is required only on OSX, 
        // otherwise the code will not work correctly on that platform          
        serverSocket.setReuseAddress(false);
        serverSocket.bind(new InetSocketAddress(InetAddress.getByName("localhost"), port), 1);
        return true;
    } catch (Exception ex) {
        return false;
    }
}       

Code :

var now = new Date();
var time = now.getTime();
time += 3600 * 1000;
now.setTime(time);
document.cookie = 
'username=' + value + 
'; expires=' + now.toUTCString() + 
'; path=/';

Simple example that works with Java 1.7 to recursively list files in directories specified on the command-line:

import java.io.File;

public class List {
    public static void main(String[] args) {
        for (String f : args) {
            listDir(f);
        }
    }

    private static void listDir(String dir) {
        File f = new File(dir);
        File[] list = f.listFiles();

        if (list == null) {
            return;
        }

        for (File entry : list) {
            System.out.println(entry.getName());
            if (entry.isDirectory()) {
                listDir(entry.getAbsolutePath());
            }
        }
    }
}

In case of a very large stream length there is the hazard of memory leak due to Large Object Heap. i.e. The byte buffer created by stream.ToArray creates a copy of memory stream in Heap memory leading to duplication of reserved memory. I would suggest to use a StreamReader, a TextWriter and read the stream in chunks of char buffers.

In netstandard2.0 System.IO.StreamReader has a method ReadBlock

you can use this method in order to read the instance of a Stream (a MemoryStream instance as well since Stream is the super of MemoryStream):

private static string ReadStreamInChunks(Stream stream, int chunkLength)
{
    stream.Seek(0, SeekOrigin.Begin);
    string result;
    using(var textWriter = new StringWriter())
    using (var reader = new StreamReader(stream))
    {
        var readChunk = new char[chunkLength];
        int readChunkLength;
        //do while: is useful for the last iteration in case readChunkLength < chunkLength
        do
        {
            readChunkLength = reader.ReadBlock(readChunk, 0, chunkLength);
            textWriter.Write(readChunk,0,readChunkLength);
        } while (readChunkLength > 0);

        result = textWriter.ToString();
    }

    return result;
}

NB. The hazard of memory leak is not fully eradicated, due to the usage of MemoryStream, that can lead to memory leak for large memory stream instance (memoryStreamInstance.Size >85000 bytes). You can use Recyclable Memory stream, in order to avoid LOH. This is the relevant library

(Analogue of https://stackoverflow.com/a/54967187/2338477, slightly modified).

Here is my own solution with minimum define magic and support of individual enum assignments.

Here is header file:

#pragma once
#include <string>
#include <map>
#include <regex>

template <class Enum>
class EnumReflect
{
public:
    static const char* getEnums() { return ""; }
};

//
//  Just a container for each enumeration type.
//
template <class Enum>
class EnumReflectBase
{
public:
    static std::map<std::string, int> enum2int;
    static std::map<int, std::string> int2enum;

    static void EnsureEnumMapReady( const char* enumsInfo )
    {
        if (*enumsInfo == 0 || enum2int.size() != 0 )
            return;

        // Should be called once per each enumeration.
        std::string senumsInfo(enumsInfo);
        std::regex re("^([a-zA-Z_][a-zA-Z0-9_]+) *=? *([^,]*)(,|$) *");     // C++ identifier to optional " = <value>"
        std::smatch sm;
        int value = 0;

        for (; regex_search(senumsInfo, sm, re); senumsInfo = sm.suffix(), value++)
        {
            string enumName = sm[1].str();
            string enumValue = sm[2].str();

            if (enumValue.length() != 0)
                value = atoi(enumValue.c_str());

            enum2int[enumName] = value;
            int2enum[value] = enumName;
        }
    }
};

template <class Enum>
std::map<std::string, int> EnumReflectBase<Enum>::enum2int;

template <class Enum>
std::map<int, std::string> EnumReflectBase<Enum>::int2enum;


#define DECLARE_ENUM(name, ...)                                         \
    enum name { __VA_ARGS__ };                                          \
    template <>                                                         \
    class EnumReflect<##name>: public EnumReflectBase<##name> {         \
    public:                                                             \
        static const char* getEnums() { return #__VA_ARGS__; }          \
    };




/*
    Basic usage:

    Declare enumeration:

DECLARE_ENUM( enumName,

    enumValue1,
    enumValue2,
    enumValue3 = 5,

    // comment
    enumValue4
);

    Conversion logic:

    From enumeration to string:

        printf( EnumToString(enumValue3).c_str() );

    From string to enumeration:

       enumName value;

       if( !StringToEnum("enumValue4", value) )
            printf("Conversion failed...");
*/

//
//  Converts enumeration to string, if not found - empty string is returned.
//
template <class T>
std::string EnumToString(T t)
{
    EnumReflect<T>::EnsureEnumMapReady(EnumReflect<T>::getEnums());
    auto& int2enum = EnumReflect<T>::int2enum;
    auto it = int2enum.find(t);

    if (it == int2enum.end())
        return "";

    return it->second;
}

//
//  Converts string to enumeration, if not found - false is returned.
//
template <class T>
bool StringToEnum(const char* enumName, T& t)
{
    EnumReflect<T>::EnsureEnumMapReady(EnumReflect<T>::getEnums());
    auto& enum2int = EnumReflect<T>::enum2int;
    auto it = enum2int.find(enumName);

    if (it == enum2int.end())
        return false;

    t = (T) it->second;
    return true;
}

And here is example test application:

DECLARE_ENUM(TestEnum,
    ValueOne,
    ValueTwo,
    ValueThree = 5,
    ValueFour = 7
);

DECLARE_ENUM(TestEnum2,
    ValueOne2 = -1,
    ValueTwo2,
    ValueThree2 = -4,
    ValueFour2
);

void main(void)
{
    string sName1 = EnumToString(ValueOne);
    string sName2 = EnumToString(ValueTwo);
    string sName3 = EnumToString(ValueThree);
    string sName4 = EnumToString(ValueFour);

    TestEnum t1, t2, t3, t4, t5 = ValueOne;
    bool b1 = StringToEnum(sName1.c_str(), t1);
    bool b2 = StringToEnum(sName2.c_str(), t2);
    bool b3 = StringToEnum(sName3.c_str(), t3);
    bool b4 = StringToEnum(sName4.c_str(), t4);
    bool b5 = StringToEnum("Unknown", t5);

    string sName2_1 = EnumToString(ValueOne2);
    string sName2_2 = EnumToString(ValueTwo2);
    string sName2_3 = EnumToString(ValueThree2);
    string sName2_4 = EnumToString(ValueFour2);

    TestEnum2 t2_1, t2_2, t2_3, t2_4, t2_5 = ValueOne2;
    bool b2_1 = StringToEnum(sName2_1.c_str(), t2_1);
    bool b2_2 = StringToEnum(sName2_2.c_str(), t2_2);
    bool b2_3 = StringToEnum(sName2_3.c_str(), t2_3);
    bool b2_4 = StringToEnum(sName2_4.c_str(), t2_4);
    bool b2_5 = StringToEnum("Unknown", t2_5);

Updated version of same header file will be kept here:

I know that question is a bit old but

In root of project where Pipfile is located you could run

pipenv --venv

which returns

/Users/your_user_name/.local/share/virtualenvs/model-N-S4uBGU

and then remove this env by typing

rm -rf /Users/your_user_name/.local/share/virtualenvs/model-N-S4uBGU

Just a helpful hint, there is a company called Yodlee.com who provides this data. They do charge for the API. Companies like Mint.com use this API to gather bank and financial account data.

Also, checkout https://plaid.com/, they are a similar company Yodlee.com and provide both authentication API for several banks and REST-based transaction fetching endpoints.

The given code given will work absolutely fine if we run from console. and there is no package name in the class

You have to make sure where you have your ".class" file. because, if package name is given for the class, you have to make sure to keep the ".class" file inside the specified folder. For example, my package name is "src.main.code" , I have to create a code folder,inside main folder, inside src folder and put Test.class in code folder. then it will work perfectly.

Even though the question is too old, but I would like to share the solution that worked for me because I already checked everything when it comes to this error. It was a pain, I spent two days trying and at the end the solution was:

update the M2e plugin in eclipse

clean and build again

you need to fill only starting 2-3 numbers (or text for that matter) and then drag the range down using fill handle. MS Excel will identify the series by itself and will fill the range till where you drag down the range. The below image shows the ‘Fill Handle’.

One can use the textract library. It take care of both "doc" as well as "docx"

import textract
text = textract.process("path/to/file.extension")

You can even use 'antiword' (sudo apt-get install antiword) and then convert doc to first into docx and then read through docx2txt.

antiword filename.doc > filename.docx

Ultimately, textract in the backend is using antiword.

in IE you can get the event object by window.event in other browsers with no 'use strict' directive, it is possible to get by arguments.callee.caller.arguments[0].

function myFunc(p1, p2, p3) {
    var evt = window.event || arguments.callee.caller.arguments[0];
}

You can execute your file by using this:

python /Users/luca/Documents/python/gameover.py

You can also run the file by moving to the path of the file you want to run and typing:

python gameover.py

Show commits and commit contents from other-branch that are not in your current branch:

git show @..other-branch

Additionally you can apply the commits from other-branch directly to your current branch:

git cherry-pick @..other-branch

I think CAST(ROUND(yourColumn,2) as varchar) should do the job.

But why do you want to do this presentational formatting in T-SQL?

Of course! jQuery is just a library that utilizes javascript after all.

You can use document.getElementById to get the element in question, then change its height accordingly, through element.style.height.

elementToChange = document.getElementById('collapseableEl');
elementToChange.style.height = '100%';

Wrap that up in a neat little function that caters for toggling back and forth and you have yourself a solution.

By registering the class (specifically its CLSID) -- see e.g. here.

I have created a javascript version of the solution Tom Bisciglia suggested.

My code allows you to use a normal image map. All you have to do is load a few lines of CSS and a few lines of JS and... BOOM... your image map has hover states and is fully responsive! Magic right?

var images = document.querySelectorAll('img[usemap]');
images.forEach( function(image) {
    var mapid = image.getAttribute('usemap').substr(1);
    var imagewidth = image.getAttribute('width');
    var imageheight = image.getAttribute('height');
    var imagemap = document.querySelector('map[name="'+mapid+'"]');
    var areas = imagemap.querySelectorAll('area');

    image.removeAttribute('usemap');
    imagemap.remove();

    // create wrapper container
    var wrapper = document.createElement('div');
    wrapper.classList.add('imagemap');
    image.parentNode.insertBefore(wrapper, image);
    wrapper.appendChild(image);

    areas.forEach( function(area) {
        var coords = area.getAttribute('coords').split(',');
        var xcoords = [parseInt(coords[0]),parseInt(coords[2])];
        var ycoords = [parseInt(coords[1]),parseInt(coords[3])];
        xcoords = xcoords.sort(function(a, b){return a-b});
        ycoords = ycoords.sort(function(a, b){return a-b});
        wrapper.innerHTML += "<a href='"+area.getAttribute('href')+"' title='"+area.getAttribute('title')+"' class='area' style='left: "+((xcoords[0]/imagewidth)*100).toFixed(2)+"%; top: "+((ycoords[0]/imageheight)*100).toFixed(2)+"%; width: "+(((xcoords[1] - xcoords[0])/imagewidth)*100).toFixed(2)+"%; height: "+(((ycoords[1] - ycoords[0])/imageheight)*100).toFixed(2)+"%;'></a>";
    });
});

img {max-width: 100%; height: auto;}

.imagemap {position: relative;}
.imagemap img {display: block;}
.imagemap .area {display: block; position: absolute; transition: box-shadow 0.15s ease-in-out;}
.imagemap .area:hover {box-shadow: 0px 0px 1vw rgba(0,0,0,0.5);}

Another option:

UPDATE `table` SET the_col = current_timestamp

Looks odd, but works as expected. If I had to guess, I'd wager this is slightly faster than calling now().

Couldn't find a straight answer, and this "scp.Client" module doesn't exist. Instead, this suits me:

from paramiko import SSHClient
from scp import SCPClient

ssh = SSHClient()
ssh.load_system_host_keys()
ssh.connect('example.com')

with SCPClient(ssh.get_transport()) as scp:
   scp.put('test.txt', 'test2.txt')
   scp.get('test2.txt')

you can use

reader.GetInt32(3);

to read an 32 bit int from the data reader.

If you know the type of your data I think its better to read using the Get* methods which are strongly typed rather than just reading an object and casting.

Have you considered using

reader.GetInt32(reader.GetOrdinal(columnName)) 

rather than accessing by position. This makes your code less brittle and will not break if you change the query to add new columns before the existing ones. If you are going to do this in a loop, cache the ordinal first.

JavaSun recomendation is to use a shared variable as a flag which asks the background thread to stop. This variable can then be set by a different object requesting the thread to terminate.

You can that way kill the other process, and the current one afterwards.

And if you're building a Windows app, use the GetFileSizeEx API as CRT file I/O is messy, especially for determining file length, due to peculiarities in file representations on different systems ;)

This could work but I don't know if it's convenient for your case:

@ViewChildren('contentPlaceholder', {read: ViewContainerRef}) viewContainerRefs: QueryList;

ngAfterViewInit() {
 this.viewContainerRefs.changes.subscribe(item => {
   if(this.viewContainerRefs.toArray().length) {
     // shown
   }
 })
}

I think it's easiest:

First set any Label as you like (Italic, Bold, Size etc.) And:

yourDataGridView.Font = anyLabel.Font;

Dont define varibale in header file , do declaration in header file(good practice ) .. in your case it is working because multiple weak symbols .. Read about weak and strong symbol ....link :http://csapp.cs.cmu.edu/public/ch7-preview.pdf

This type of code create problem while porting.

When your program has more open descriptors than the open files ulimit (ulimit -a will list this), the kernel will refuse to open any more file descriptors. Make sure you don't have any file descriptor leaks - for example, by running it for a while, then stopping and seeing if any extra fds are still open when it's idle - and if it's still a problem, change the nofile ulimit for your user in /etc/security/limits.conf

A comment is produced using the REM command which is short for "Remark".

REM Comment here...

I don't have an answer as to what is actually wrong or to directly fix it.

I can report that exporting all the code and forms, then importing them into a fresh workbook fixed it for me. All the work was recovered, and nothing more needed to be done to get back to work. Since that works, it seems clear that it must be a bug in Excel, or whatever it is would still be missing in the new version.

I do have a possible clue to how this Excel (2007) bug works. It seems to be associated with the removal of a class module (or two). (But not every class module, every time for some reason.) No code was using any part of the removed modules (or the new imported version would not work either). One module had been cut down to nothing but some comments (in hope of removing anything that could be "missing" later) so that there was no code visibly connecting it to any other part of the project. But the error came up shortly after I removed the code module entirely. The error also stopped when the removed (but exported just in case) modules were returned. So for convenience, this project had been packing two unused code modules to avoid this error.

It appears then, that somehow some element of some departed modules remains in the VBA environment, even if nothing is being used from these (there two in this case) class modules anywhere in the project. Consequently, the debug/compile finds that element, and it is no surprise that something is missing because it is. Since the thing that is missing is nowhere in the project there is nothing to highlight so there is a message only and nothing else happens. That would explain the observed behavior.

I'm assuming your first string is an actual Date object, please correct me if I'm wrong. If so, use the SimpleDateFormat object: http://download.oracle.com/javase/6/docs/api/java/text/SimpleDateFormat.html. The format string "h:mm" should take care of it.

Could you check if the problem with IE relies on not defining security zones to allow cross domain requests? See this microsoft page for an explanation.

OTOH, this page mentions that IE7 and eariler cannot do cross domain calls, but IE8 can, using a different object than XMLHttpRequest, the one JQuery uses. Could you check if XDomainRequest works?

EDIT (2013-08-22)

The second link is dead, so I'm writing here some of its information, taken from the wayback machine:

XDomainRequest Supported: IE8

Rather than implement the CORS version of XMLHttpRequest, the IE team have gone with there own propriety object, named XDomainRequest. The usage of XDomainRequest has been simplified from XMLHttpRequest, by having more events thrown (with onload perhaps being the most important).

This implementation has a few limitations attached to it. For example, cookies are not sent when using this object, which can be a headache for cookie based sessions on the server side. Also, ContentType can not be set, which poses a problem in ASP.NET and possibly other server side languages (see http://www.actionmonitor.co.uk/NewsItem.aspx?id=5).

var xdr = new XDomainRequest();
xdr.onload = function() { alert("READY"); };
xdr.open("GET", "script.html");
xdr.send();

IMHO I think that all the models have a great place but the problem I have with the model first approach is in many large businesses with DBA's controlling the databases you do not get the flexibility of building applications without using database first approaches. I have worked on many projects and when it came to deployment they wanted full control.

So as much as I agree with all the possible variations Code First, Model First, Database first, you must consider the actual production environment. So if your system is going to be a large user base application with many users and DBA's running the show then you might consider the Database first option just my opinion.

You can use DataFrame constructor with lists created by to_list:

import pandas as pd

d1 = {'teams': [['SF', 'NYG'],['SF', 'NYG'],['SF', 'NYG'],
                ['SF', 'NYG'],['SF', 'NYG'],['SF', 'NYG'],['SF', 'NYG']]}
df2 = pd.DataFrame(d1)
print (df2)
       teams
0  [SF, NYG]
1  [SF, NYG]
2  [SF, NYG]
3  [SF, NYG]
4  [SF, NYG]
5  [SF, NYG]
6  [SF, NYG]

df2[['team1','team2']] = pd.DataFrame(df2.teams.tolist(), index= df2.index)
print (df2)
       teams team1 team2
0  [SF, NYG]    SF   NYG
1  [SF, NYG]    SF   NYG
2  [SF, NYG]    SF   NYG
3  [SF, NYG]    SF   NYG
4  [SF, NYG]    SF   NYG
5  [SF, NYG]    SF   NYG
6  [SF, NYG]    SF   NYG

And for new DataFrame:

df3 = pd.DataFrame(df2['teams'].to_list(), columns=['team1','team2'])
print (df3)
  team1 team2
0    SF   NYG
1    SF   NYG
2    SF   NYG
3    SF   NYG
4    SF   NYG
5    SF   NYG
6    SF   NYG

Solution with apply(pd.Series) is very slow:

#7k rows
df2 = pd.concat([df2]*1000).reset_index(drop=True)

In [121]: %timeit df2['teams'].apply(pd.Series)
1.79 s ± 52.5 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)

In [122]: %timeit pd.DataFrame(df2['teams'].to_list(), columns=['team1','team2'])
1.63 ms ± 54.3 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)

import re

url = '<p>Hello World</p><a href="http://example.com">More Examples</a><a href="http://example2.com">Even More Examples</a>'

urls = re.findall('https?://(?:[-\w.]|(?:%[\da-fA-F]{2}))+', url)

>>> print urls
['http://example.com', 'http://example2.com']

yes, Scrapy can scrap dynamic websites, website that are rendered through javaScript.

There are Two approaches to scrapy these kind of websites.

First,

you can use splash to render Javascript code and then parse the rendered HTML. you can find the doc and project here Scrapy splash, git

Second,

As everyone is stating, by monitoring the network calls, yes, you can find the api call that fetch the data and mock that call in your scrapy spider might help you to get desired data.

Non-reflective solution for Java 8, without using a series of if's, would be to stream all fields and check for nullness:

return Stream.of(id, name).allMatch(Objects::isNull);

This remains quite easy to maintain while avoiding the reflection hammer. This will return true for null attributes.

I have found that the problem with IE is that it sniffs the return data and makes up its own mind about what content-type it thinks it has been sent. There are a number of side effect that this causes, such as always openning a saveAs dialog for text files because you are using compression of data trasnferes. The solution is (in php code)......

header('X-Content-Type-Options: nosniff');

First please check in module.ts file that in @NgModule all properties are only one time. If any of are more than one time then also this error come. Because I had also occur this error but in module.ts file entryComponents property were two time that's why I was getting this error. I resolved this error by removing one time entryComponents from @NgModule. So, I recommend that first you check it properly.

That's because the json you're getting is an array of your RootObject class, rather than a single instance, change your DeserialiseObject<RootObject> to be something like DeserialiseObject<RootObject[]> (un-tested).

You'll then have to either change your method to return a collection of RootObject or do some further processing on the deserialised object to return a single instance.

If you look at a formatted version of the response you provided:

[
   {
      "id":3636,
      "is_default":true,
      "name":"Unit",
      "quantity":1,
      "stock":"100000.00",
      "unit_cost":"0"
   },
   {
      "id":4592,
      "is_default":false,
      "name":"Bundle",
      "quantity":5,
      "stock":"100000.00",
      "unit_cost":"0"
   }
]

You can see two instances in there.

You can get the desired result with the code below. Two'H' in HH is for 24-hour format.

return fechaHora.Value.ToString("HH:mm");

Ruby 2.5+

As of Ruby 2.5 you can use delete_prefix or delete_prefix! to achieve this in a readable manner.

In this case "[12,23,987,43".delete_prefix("[").

More info here:

• Official docs

• https://blog.jetbrains.com/ruby/2017/10/10-new-features-in-ruby-2-5/

• https://bugs.ruby-lang.org/issues/12694

'invisible'.delete_prefix('in') #=> "visible"
'pink'.delete_prefix('in') #=> "pink"

N.B. you can also use this to remove items from the end of a string with delete_suffix and delete_suffix!

'worked'.delete_suffix('ed') #=> "work"
'medical'.delete_suffix('ed') #=> "medical"

• Docs
• https://bugs.ruby-lang.org/issues/13665

Edit:

Using the Tin Man's benchmark setup, it looks pretty quick too (under the last two entries delete_p and delete_p!). Doesn't quite pip the previous faves for speed, though is very readable.

N.B : IF YOU ARE USING PHPSTORM

I spent an hour trying to solve this problem, thinking that it was my php server problem, So i set 'always_populate_raw_post_data' to '-1' in php.ini and nothing worked.

Until i found out that using phpStorm built in server is what causing the problem as detailed in the answer here : Answer by LazyOne Here , So i thought about sharing it.

You can use three different ways

1. ref / out parameters

using ref:

static void Main(string[] args)
{
    int a = 10;
    int b = 20;
    int add = 0;
    int multiply = 0;
    Add_Multiply(a, b, ref add, ref multiply);
    Console.WriteLine(add);
    Console.WriteLine(multiply);
}

private static void Add_Multiply(int a, int b, ref int add, ref int multiply)
{
    add = a + b;
    multiply = a * b;
}

using out:

static void Main(string[] args)
{
    int a = 10;
    int b = 20;
    int add;
    int multiply;
    Add_Multiply(a, b, out add, out multiply);
    Console.WriteLine(add);
    Console.WriteLine(multiply);
}

private static void Add_Multiply(int a, int b, out int add, out int multiply)
{
    add = a + b;
    multiply = a * b;
}

2. struct / class

using struct:

struct Result
{
    public int add;
    public int multiply;
}
static void Main(string[] args)
{
    int a = 10;
    int b = 20;
    var result = Add_Multiply(a, b);
    Console.WriteLine(result.add);
    Console.WriteLine(result.multiply);
}

private static Result Add_Multiply(int a, int b)
{
    var result = new Result
    {
        add = a * b,
        multiply = a + b
    };
    return result;
}

using class:

class Result
{
    public int add;
    public int multiply;
}
static void Main(string[] args)
{
    int a = 10;
    int b = 20;
    var result = Add_Multiply(a, b);
    Console.WriteLine(result.add);
    Console.WriteLine(result.multiply);
}

private static Result Add_Multiply(int a, int b)
{
    var result = new Result
    {
        add = a * b,
        multiply = a + b
    };
    return result;
}

3. Tuple

Tuple class

static void Main(string[] args)
{
    int a = 10;
    int b = 20;
    var result = Add_Multiply(a, b);
    Console.WriteLine(result.Item1);
    Console.WriteLine(result.Item2);
}

private static Tuple<int, int> Add_Multiply(int a, int b)
{
    var tuple = new Tuple<int, int>(a + b, a * b);
    return tuple;
}

C# 7 Tuples

static void Main(string[] args)
{
    int a = 10;
    int b = 20;
    (int a_plus_b, int a_mult_b) = Add_Multiply(a, b);
    Console.WriteLine(a_plus_b);
    Console.WriteLine(a_mult_b);
}

private static (int a_plus_b, int a_mult_b) Add_Multiply(int a, int b)
{
    return(a + b, a * b);
}

One thing that i do is df=df.reset_index() then df=df.drop(['index'],axis=1)

You can not do that directly. You need to use std::remove algorithm to move the element to be erased to the end of the vector and then use erase function. Something like: myVector.erase(std::remove(myVector.begin(), myVector.end(), 8), myVec.end());. See this erasing elements from vector for more details.

I am not sure,how you are opening popup or say model in your code. But you can try something like this..

    myApp.controller('MyController', function ($scope) {
      $scope.open = function(){
        var modalInstance = $modal.open({
                        templateUrl: '/assets/yourOpupTemplatename.html',
                        backdrop:'static',
                        keyboard:false,
                        controller: function($scope, $modalInstance) {
                            $scope.cancel = function() {
                                $modalInstance.dismiss('cancel');
                            };
                            $scope.ok = function () {
                              $modalInstance.close();
                            };
                        }
                    });
      }
    });
</script>

Java has a LinkedList implementation, that you might wanna check out. You can download the JDK and it's sources at java.sun.com.

An IEnumerator is a thing that can enumerate: it has the Current property and the MoveNext and Reset methods (which in .NET code you probably won't call explicitly, though you could).

An IEnumerable is a thing that can be enumerated...which simply means that it has a GetEnumerator method that returns an IEnumerator.

Which do you use? The only reason to use IEnumerator is if you have something that has a nonstandard way of enumerating (that is, of returning its various elements one-by-one), and you need to define how that works. You'd create a new class implementing IEnumerator. But you'd still need to return that IEnumerator in an IEnumerable class.

For a look at what an enumerator (implementing IEnumerator<T>) looks like, see any Enumerator<T> class, such as the ones contained in List<T>, Queue<T>, or Stack<T>. For a look at a class implementing IEnumerable, see any standard collection class.

Syntax

 Datatype[] variable = new Datatype[] { value1,value2.... }

 Datatype variable[]  = new Datatype[] { value1,value2.... }

Example :

int [] points = new int[]{ 1,2,3,4 };

No. gettimeofday should NEVER be used to measure time.

This is causing bugs all over the place. Please don't add more bugs.

You can use charAt() function to find out spaces in string.

 public class Test {
  public static void main(String args[]) {
   String fav="Hi Testing  12 3";
   int counter=0;
   for( int i=0; i<fav.length(); i++ ) {
    if(fav.charAt(i) == ' ' ) {
     counter++;
      }
     }
    System.out.println("Number of spaces "+ counter);
    //This will print Number of spaces 4
   }
  }

You can set the default like this:

b = models.CharField(max_length=7,default="foobar")

and then you can hide the field with your model's Admin class like this:

class SomeModelAdmin(admin.ModelAdmin):
    exclude = ("b")

Yes, this is something that you should worry about. Check the length of your objects with nrow(). R can auto-replicate objects so that they're the same length if they differ, which means you might be performing operations on mismatched data.

In this case you have an obvious flaw in that your subtracting aggregated data from raw data. These will definitely be of different lengths. I suggest that you merge them as time series (using the dates), then locf(), then do your subtraction. Otherwise merge them by truncating the original dates to the same interval as the aggregated series. Just be very careful that you don't drop observations.

Lastly, as some general advice as you get started: look at the result of your computations to see if they make sense. You might even pull them into a spreadsheet and replicate the results.

Applicable for Eclipse Luna + Eclipse Git 3.6.1

I,

1. cloned git repository
2. made some changes in source code
3. staged changes from Git Staging View
4. finally, commit and Push!

And I faced this issue with EGit and here is how I fixed it..

Yes, someone committed the changes before I commit my changes. So the changes are rejected. After this error, the changes gets actually committed to local repository. I did not want to just Pull the changes because I wanted to maintain linear history as pointed out in - In what cases could `git pull` be harmful?

So, I executed following steps

1. from Git Repository perspective, right click on the concerned Git
   project
2. select Fetch from Upstream - it fetches remote updates (refs and objects) but no updates are made locally. for more info refer What is the difference between 'git pull' and 'git fetch'?
3. select Rebase... - this open a popup, click on Preserve merges during rebase see why
   What exactly does git's "rebase --preserve-merges" do (and why?)
4. click on Rebase button
5. if there is/are a conflict(s), go to step 6 else step 11
6. a Rebase Result popup would appear, just click on OK
7. file comparator would open up, you need to modify left side file.
8. once you are done with merging changes correctly, goto Git Staging view
9. stage the changes. i.e. add to index
10. on the same view, click on Rebase-> Continue. repeat 7 to 10 until all conflicts are resolved.
11. from History view, select your commit row and select Push Commit
12. select Rebase Commits of local....... checkbox and click next. refer why - Git: rebase onto development branch from upstream
13. click on Finish

Note: if you have multiple local repository commits, you need to squash them in one commit to avoid multiple merges.

I've used the "slugify" method from underscore.string and it worked like a charm:

https://github.com/epeli/underscore.string#slugifystring--string

The cool thing is that you can really just import this method, don't need to import the entire library.

To get an object from a xib file programatically you can use: [[NSBundle mainBundle] loadNibNamed:@"MyXibName" owner:self options:nil] which returns an array of the top level objects in the xib.

So, you could do something like this:

UIView *rootView = [[[NSBundle mainBundle] loadNibNamed:@"MyRootView" owner:self options:nil] objectAtIndex:0];
UIView *containerView = [[[NSBundle mainBundle] loadNibNamed:@"MyContainerView" owner:self options:nil] lastObject];
[rootView addSubview:containerView];
[self.view addSubview:rootView];

You can try this.

XML Document

Save as employees.xml.

The class have following methods

• List item
• A Method that will return the Employee Name for input ID.
• A Method that will return list of Employees Name with age greater than the input age.
• A Method that will return list of Female Employees Name.

it could be also you are trying to index in the wrong way:

a = 'apple'
a(3) ===> 'str' object is not callable

a[3] = l

<a href="home.php?click=1" class="btn">Click me</a>
<?php 
  if($_GET['click']){
    doSomething();
  }
?>

But is better to use JS and with ajax to call function!

You can also use the box-shadow property to simulate an underline.

Here is a fiddle. The idea is to use two layered box shadows to position the line in the same place as an underline.

a.underline {
    text-decoration: none;
    box-shadow: inset 0 -4px 0 0 rgba(255, 255, 255, 1), inset 0 -5px 0 0 rgba(255, 0, 0, 1);
}

I have a simpler and elegant solution that doesn't mess up with classes, styles, opacities and stuff.

For the draggable element - you add 'start' event which will execute every time you try to move the element somewhere. You will have a condition which move is not legal. For the moves that are illegal - prevent them with 'e.preventDefault();' like in the code below.

    $(".disc").draggable({
        revert: "invalid", 
        cursor: "move",
        start: function(e, ui){                
            console.log("element is moving");

            if(SOME_CONDITION_FOR_ILLEGAL_MOVE){
                console.log("illegal move");
                //This will prevent moving the element from it's position
                e.preventDefault();
            }    

        }
    });

You are welcome :)

If you wanted to learn some GUI, may be tic tac toe is good. Even for console, I still find that is a fun problem. Not challenging but a little bit fun. Later you can advance some other games or port that game to GUI, client server or java applet for the web. I think if you want to learn something and get fun as well, game is a good choice:)

You should use dateutil. With that, you can use relativedelta, it's an improved version of timedelta.

>>> import datetime 
>>> import dateutil.relativedelta
>>> now = datetime.datetime.now()
>>> print now
2012-03-15 12:33:04.281248
>>> print now + dateutil.relativedelta.relativedelta(months=-1)
2012-02-15 12:33:04.281248

Use this in your code:

String.valueOf(x);

You are getting this error because the parameter required is Activity and you are passing it the Application. So, either you cast application to the Activity like: (Activity)getApplicationContext(); Or you can just type the Activity like: MyActivity.this

For a string such as #box2, this should work:

var thenum = thestring.replace(/^.*?(\d+).*/,'$1');

i faced the same problem but i solved it by moving the chromedriver to this path '/opt/google/chrome/'

and this code works correctly

from selenium.webdriver import Chrome
driver = Chrome('/opt/google/chrome/chromedrive')
driver.get('https://google.com')

SELECT k.column_name
FROM information_schema.key_column_usage k   
WHERE k.table_name = 'YOUR TABLE NAME' AND k.constraint_name LIKE 'pk%'

I would recommend you to watch all the fields

For me, this problem was due to the fact that I had not appropriately sym-linked the cv2.so file in the~/.virtualenvs/cv/lib/python3.5/site-packages folder (the name of your virualenv may not be "cv", your version of python may not be 3.5--adjust accordingly).

If you go to the ~/.virtualenvs/cv/lib/python3.5/site-packages folder and ls, the cv2.so file should appear in light blue (Ubuntu 16.04) showing that it is linked. You can check the link location by typing: readlink cv2.so

If cv2.so appears in red (as mine did), rm the file and type: (for my install of python 3.5)

ln -s /usr/local/lib/python3.5/dist-packages/cv2.cpython-35m-x86_64-linux-gnu.so cv2.so

OR (if you have python 3.6)

ln -s /usr/local/lib/python3.6/dist-packages/cv2.cpython-36m-x86_64-linux-gnu.so cv2.so

If you are working in python 2.6 or python 2.7, you instead type:

ln -s /usr/local/lib/python2.7/dist-packages/cv2.so cv2.so

If the cv2.so or cv2.cpython-36m-x86_64-linux-gnu.so files do not exist in your /usr/local/lib/python***/dist-packages location, check to see if they're in a /usr/local/lib/python***/sites-packages folder. If so, adjust the path accordingly. If not, something has gone wrong with your opencv installation.

With CSS 2 you can do this:

Instead of explaining it with words, here's an example. This is a Scheme version of the factorial function:

(define (factorial x)
  (if (= x 0) 1
      (* x (factorial (- x 1)))))

Here is a version of factorial that is tail-recursive:

(define factorial
  (letrec ((fact (lambda (x accum)
                   (if (= x 0) accum
                       (fact (- x 1) (* accum x))))))
    (lambda (x)
      (fact x 1))))

You will notice in the first version that the recursive call to fact is fed into the multiplication expression, and therefore the state has to be saved on the stack when making the recursive call. In the tail-recursive version there is no other S-expression waiting for the value of the recursive call, and since there is no further work to do, the state doesn't have to be saved on the stack. As a rule, Scheme tail-recursive functions use constant stack space.

If you are using new version of Kafka e.g. 5.3.3, you can use

kafka-broker-api-versions  --bootstrap-server BROKER | grep 9092

You just need to pass one of the brokers

Boostrap 3 has a component for exactly this. It's:

<span class="badge">100</span>

An atomic reference is ideal to use when you need to share and change the state of an immutable object between multiple threads. That is a super dense statement so I will break it down a bit.

First, an immutable object is an object that is effectively not changed after construction. Frequently an immutable object's methods return new instances of that same class. Some examples include the wrapper classes of Long and Double, as well as String, just to name a few. (According to Programming Concurrency on the JVM immutable objects are a critical part of modern concurrency).

Next, why AtomicReference is better than a volatile object for sharing that shared value. A simple code example will show the difference.

volatile String sharedValue;
static final Object lock=new Object();
void modifyString(){
  synchronized(lock){
    sharedValue=sharedValue+"something to add";
  }
}

Every time you want to modify the string referenced by that volatile field based on its current value, you first need to obtain a lock on that object. This prevents some other thread from coming in during the meantime and changing the value in the middle of the new string concatenation. Then when your thread resumes, you clobber the work of the other thread. But honestly that code will work, it looks clean, and it would make most people happy.

Slight problem. It is slow. Especially if there is a lot of contention of that lock Object. Thats because most locks require an OS system call, and your thread will block and be context switched out of the CPU to make way for other processes.

The other option is to use an AtomicRefrence.

public static AtomicReference<String> shared = new AtomicReference<>();
String init="Inital Value";
shared.set(init);
//now we will modify that value
boolean success=false;
while(!success){
  String prevValue=shared.get();
  // do all the work you need to
  String newValue=shared.get()+"lets add something";
  // Compare and set
  success=shared.compareAndSet(prevValue,newValue);
}

Now why is this better? Honestly that code is a little less clean than before. But there is something really important that happens under the hood in AtomicRefrence, and that is compare and swap. It is a single CPU instruction, not an OS call, that makes the switch happen. That is a single instruction on the CPU. And because there are no locks, there is no context switch in the case where the lock gets exercised which saves even more time!

The catch is, for AtomicReferences, this does not use a .equals() call, but instead an == comparison for the expected value. So make sure the expected is the actual object returned from get in the loop.

I know you asked about Linux and Mac; I am going to provide the answer for Windows, in case other people who are interested in Windows find your question .

Windows includes a Javascript engine that can be used from the command line.

All versions of Windows, since Windows 98, have included something called "The Windows Script Host". It's a windows-standard way to support script "engines". Since the first release, WSH supports JScript, Microsoft's version of Javascript. Among other things, this means that, from a windows command line, you can just invoke the name of any *.js file, and it will run in the JScript engine. (via either wscript.exe or cscript.exe)

You can see this question: What is the ProgId or CLSID for IE9's Javascript engine (code-named "Chakra") to learn how to invoke the higher-performance IE9 Javascript engine from cscript.exe.

https://docs.oracle.com/javase/8/docs/platform/serialization/spec/serialTOC.html

Default serialization is somewhat verbose, and assumes the widest possible usage scenario of the serialized object, and accordingly the default format (Serializable) annotates the resultant stream with information about the class of the serialized object.

Externalization give the producer of the object stream complete control over the precise class meta-data (if any) beyond the minimal required identification of the class (e.g. its name). This is clearly desirable in certain situations, such as closed environments, where producer of the object stream and its consumer (which reifies the object from the stream) are matched, and additional metadata about the class serves no purpose and degrades performance.

Additionally (as Uri point out) externalization also provides for complete control over the encoding of the data in the stream corresponding to Java types. For (a contrived) example, you may wish to record boolean true as 'Y' and false as 'N'. Externalization allows you to do that.

Got the answer HERE for windows, it says there that:

curl -XPUT 'http://localhost:9200/api/twittervnext/tweet'

Woops, first try and already an error:

curl: (1) Protocol 'http not supported or disabled in libcurl

The reason for this error is kind of stupid, Windows doesn’t like it when you are using single quotes for commands. So the correct command is:

curl –XPUT "http://localhost:9200/api/twittervnext/tweet"

Sounds like myversioncontrol.com have added a pre-commit hook, or have one that is now failing. If it's a free account, it might be you've exceeded some sort of monthly commit or bandwidth limit. Check their terms of service and/or contact them to see what's up.

UPDATE:
I've just checked their website, and it looks like the free account is only valid for 30 days, so you might've exceeded that. You may need to pony up the £3.50pcm or find somewhere else (Google Code is one suggestion, though there are others).

Simon Groenewolt makes a good point that you may have changed something in the control panel on their website that has turned on a pre-commit hook but where it's configured incorrectly.

you need to convert to char first because converting to int adds those days to 1900-01-01

select CONVERT (datetime,convert(char(8),rnwl_efctv_dt ))

here are some examples

select CONVERT (datetime,5)

1900-01-06 00:00:00.000

select CONVERT (datetime,20100101)

blows up, because you can't add 20100101 days to 1900-01-01..you go above the limit

convert to char first

declare @i int
select @i = 20100101
select CONVERT (datetime,convert(char(8),@i))

'\r' = carriage return and '\n' = line feed.

In fact, there are some different behaviors when you use them in different OSes. On Unix it is '\n', but it is '\r''\n' on Windows.

Here is an approach that doesn't require the use of a for loop or defining an intermediate function or lambda function (and is also a one-liner). The method combines the following two ideas:

• calling the iter() built-in function with the optional sentinel argument, and

• using the itertools recipe for advancing an iterator n steps (see the recipe for consume()).

Putting these together, we get:

next(islice(iter(do, object()), 3, 3), None)

(The idea to pass object() as the sentinel comes from this accepted Stack Overflow answer.)

And here is what this looks like from the interactive prompt:

>>> def do():
...   print("called")
... 
>>> next(itertools.islice(iter(do, object()), 3, 3), None)
called
called
called

You can add a form onsubmit handler, something like:

<form onsubmit="return validate();">

</form>


<script>function validate() {
 // check if input is bigger than 3
 var value = document.getElementById('titleeee').value;
 if (value.length < 3) {
   return false; // keep form from submitting
 }

 // else form is good let it submit, of course you will 
 // probably want to alert the user WHAT went wrong.

 return true;
}</script>

playing with globals() makes it possible:

import random

alphabet = tuple('abcdefghijklmnopqrstuvwxyz')


print '\n'.join(repr(u) for u in globals() if not u.startswith('__'))

for i in xrange(8):
    globals()[''.join(random.sample(alphabet,random.randint(3,26)))] = random.choice(alphabet)

print

print '\n'.join(repr((u,globals()[u])) for u in globals() if not u.startswith('__'))

one result:

'alphabet'
'random'

('hadmgoixzkcptsbwjfyrelvnqu', 'h')
('nzklv', 'o')
('alphabet', ('a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z'))
('random', <module 'random' from 'G:\Python27\lib\random.pyc'>)
('ckpnwqguzyslmjveotxfbadh', 'f')
('i', 7)
('xwbujzkicyd', 'j')
('isjckyngxvaofdbeqwutl', 'n')
('wmt', 'g')
('aesyhvmw', 'q')
('azfjndwhkqgmtyeb', 'o')

I used random because you don't explain which names of "variables" to give, and which values to create. Because i don't think it's possible to create a name without making it binded to an object.

The web server is prompting you for a SPNEGO (Simple and Protected GSSAPI Negotiation Mechanism) token.

This is a Microsoft invention for negotiating a type of authentication to use for Web SSO (single-sign-on):

• either NTLM
• or Kerberos.

See:

• Microsoft MSDN Library: HTTP-Based Cross-Platform Authentication by Using the Negotiate Protocol
• RFC 4178: The Simple and Protected Generic Security Service Application Program Interface (GSS-API) Negotiation Mechanism

You can use following as well

<string name="spelatonertext3"> "-4,  5, -5,   6,  -6, "> </string>

Difficult task. I would normally suggest to grab a debugger/memory profiler like Valgrind and run the programs one after one in it. Soon or later you will find the program that leaks and can tell it the devloper or fix it yourself.

You can use reflection to find all the get methods in your DAO objects and call the equivalent set method in the DTO. This will only work if all such methods exist. It should be easy to find example code for this.

I recently got the same issue. Below solution is work for me:

        let strValue = "123"
        let result = (strValue as NSString).integerValue

I'm using Phpass which is a simple one-file PHP class that could be implemented very easily in nearly every PHP project. See also The H.

By default it used strongest available encryption that is implemented in Phpass, which is bcrypt and falls back to other encryptions down to MD5 to provide backward compatibility to frameworks like Wordpress.

The returned hash could be stored in database as it is. Sample use for generating hash is:

$t_hasher = new PasswordHash(8, FALSE);
$hash = $t_hasher->HashPassword($password);

To verify password, one can use:

$t_hasher = new PasswordHash(8, FALSE);
$check = $t_hasher->CheckPassword($password, $hash);

You should use bootstrap column nesting.

See Bootstrap 3 or Bootstrap 4:

<div class="row">
    <div class="col-md-5">Span 5</div>
    <div class="col-md-3">Span 3<br />second line</div>
    <div class="col-md-2">
        <div class="row">
            <div class="col-md-12">Span 2</div>
        </div>
        <div class="row">
            <div class="col-md-12">Span 2</div>
        </div>
    </div>
    <div class="col-md-2">Span 2</div>
</div>
<div class="row">
    <div class="col-md-6">
        <div class="row">
            <div class="col-md-12">Span 6</div>
            <div class="col-md-12">Span 6</div>
        </div>
    </div>
    <div class="col-md-6">Span 6</div>
</div>

http://jsfiddle.net/DRanJ/125/

(In Fiddle screen, enlarge your test screen to see the result, because I'm using col-md-*, then responsive stacks columns)

Note: I am not sure that BS2 allows columns nesting, but in the answer of Paul Keister, the columns nesting is not used. You should use it and avoid to reinvente css while bootstrap do well.

The columns height are auto, if you add a second line (like I do in my example), column height adapt itself.

Why not just, a=a(~~a) or a(~a)=[]. It's equivalent to the other approaches but certainly less key strokes.

Requesting Permissions In the following code, we will ask for camera permission:

in java

EasyPermissions is a wrapper library to simplify basic system permissions logic when targeting Android M or higher.

Installation EasyPermissions is installed by adding the following dependency to your build.gradle file:

dependencies {

    // For developers using AndroidX in their applications
    implementation 'pub.devrel:easypermissions:3.0.0'

    // For developers using the Android Support Library
    implementation 'pub.devrel:easypermissions:2.0.1'

}


private void askAboutCamera(){

        EasyPermissions.requestPermissions(
                this,
                "A partir deste ponto a permissão de câmera é necessária.",
                CAMERA_REQUEST_CODE,
                Manifest.permission.CAMERA );
}

You need to install the provisioning profile (drag and drop it into iTunes). Then drag and drop the .ipa. Ensure you device is set to sync apps, and try again.

"External table is not in the expected format." typically occurs when trying to use an Excel 2007 file with a connection string that uses: Microsoft.Jet.OLEDB.4.0 and Extended Properties=Excel 8.0

Using the following connection string seems to fix most problems.

public static string path = @"C:\src\RedirectApplication\RedirectApplication\301s.xlsx";
public static string connStr = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + path + ";Extended Properties=Excel 12.0;";

This did the trick for me. It captures all the stdout output from the subprocess(For python 3.8):

from subprocess import check_output, STDOUT
cmd = "Your Command goes here"
try:
    cmd_stdout = check_output(cmd, stderr=STDOUT, shell=True).decode()
except Exception as e:
    print(e.output.decode()) # print out the stdout messages up to the exception
    print(e) # To print out the exception message

when in kotlin it will look like this :

editText.setOnFocusChangeListener { view, hasFocus ->
        if (hasFocus) toast("focused") else toast("focuse lose")
    }

1. set the classpath and compile

   javac -classpath "C:\Program Files\Java\jdk1.6.0_updateVersion\tools.jar" yourApp.java

2. create manifest.txt

   Main-Class: yourApp newline

3. create yourApp.jar

   jar cvf0m yourApp.jar manifest.txt yourApp.class

4. run yourApp.jar

   java -jar yourApp.jar

The problem isn't that null cannot be assigned to an int?. The problem is that both values returned by the ternary operator must be the same type, or one must be implicitly convertible to the other. In this case, null cannot be implicitly converted to int nor vice-versus, so an explict cast is necessary. Try this instead:

int? accom = (accomStr == "noval" ? (int?)null : Convert.ToInt32(accomStr));

It seems like a much better solution to just use BitsTransfer, it seems to come OOTB on most Windows machines with PowerShell 2.0 or greater.

“C:\Users\admin\Downloads\sqldeveloper\sqldeveloper\bin\sqldeveloper.conf” is misleading, it’s not the file which sets the Java Home variable. The actually file used is”%AppData%\sqldeveloper{PRODUCT_VERSION}\product.conf” [in my case it is "%AppData%\sqldeveloper\1.0.0.0.0\product.conf"]

When nesting repetition operators, make absolutely sure that there is only one way to match the same match.

If you want a list of columns of a certain type, you can use groupby:

>>> df = pd.DataFrame([[1, 2.3456, 'c', 'd', 78]], columns=list("ABCDE"))
>>> df
   A       B  C  D   E
0  1  2.3456  c  d  78

[1 rows x 5 columns]
>>> df.dtypes
A      int64
B    float64
C     object
D     object
E      int64
dtype: object
>>> g = df.columns.to_series().groupby(df.dtypes).groups
>>> g
{dtype('int64'): ['A', 'E'], dtype('float64'): ['B'], dtype('O'): ['C', 'D']}
>>> {k.name: v for k, v in g.items()}
{'object': ['C', 'D'], 'int64': ['A', 'E'], 'float64': ['B']}

Microsoft Windows: Windows kernel forbids the use of characters in range 1-31 (i.e., 0x01-0x1F) and characters " * : < > ? \ |. Although NTFS allows each path component (directory or filename) to be 255 characters long and paths up to about 32767 characters long, the Windows kernel only supports paths up to 259 characters long. Additionally, Windows forbids the use of the MS-DOS device names AUX, CLOCK$, COM1, COM2, COM3, COM4, COM5, COM6, COM7, COM8, COM9, CON, LPT1, LPT2, LPT3, LPT4, LPT5, LPT6, LPT7, LPT8, LPT9, NUL and PRN, as well as these names with any extension (for example, AUX.txt), except when using Long UNC paths (ex. \.\C:\nul.txt or \?\D:\aux\con). (In fact, CLOCK$ may be used if an extension is provided.) These restrictions only apply to Windows - Linux, for example, allows use of " * : < > ? \ | even in NTFS.

If you use JDK version from 9+, you should select

Run > Edit Configurations... > Select JUnit template.

Then, select @argfile (Java 9+) as in the image below. Please try it. Good luck friends.

You need to say math.sqrt when you use it. Or, do from math import sqrt.

Hmm, I just read your question more thoroughly.... How are you importing math? I just tried import math and then math.sqrt which worked perfectly. Are you doing something like import math as m? If so, then you have to prefix the function with m (or whatever name you used after as).

pow is working because there are two versions: an always available version in __builtin__, and another version in math.

If you like to add support to IOS7 IOS8 you can apply this code into your project .

Integer object would be best. If you must use primitives you can use a value that does not exist in your use case. Negative height does not exist for people, so

public int getHeight(String name){
    if(map.containsKey(name)){
        return map.get(name);
    }else{
        return -1;
    }
}

tar (tape archives) - Format used is file written in serial units of fileName, fileSize, fileData - no compression. can be huge

Jar (java archive) - compression techniques used - generally contains java information like class/java files. But can contain any files and directory structure

war (web application archives) - similar like jar files only have specific directory structure as per JSP/Servlet spec for deployment purposes

ear (enterprise archives) - similar like jar files. have directory structure following J2EE requirements so that it can be deployed on J2EE application servers. - can contain multiple JAR and WAR files

I'm the author of the AI program that others have mentioned in this thread. You can view the AI in action or read the source.

Currently, the program achieves about a 90% win rate running in javascript in the browser on my laptop given about 100 milliseconds of thinking time per move, so while not perfect (yet!) it performs pretty well.

Since the game is a discrete state space, perfect information, turn-based game like chess and checkers, I used the same methods that have been proven to work on those games, namely minimax search with alpha-beta pruning. Since there is already a lot of info on that algorithm out there, I'll just talk about the two main heuristics that I use in the static evaluation function and which formalize many of the intuitions that other people have expressed here.

Monotonicity

This heuristic tries to ensure that the values of the tiles are all either increasing or decreasing along both the left/right and up/down directions. This heuristic alone captures the intuition that many others have mentioned, that higher valued tiles should be clustered in a corner. It will typically prevent smaller valued tiles from getting orphaned and will keep the board very organized, with smaller tiles cascading in and filling up into the larger tiles.

Here's a screenshot of a perfectly monotonic grid. I obtained this by running the algorithm with the eval function set to disregard the other heuristics and only consider monotonicity.

Smoothness

The above heuristic alone tends to create structures in which adjacent tiles are decreasing in value, but of course in order to merge, adjacent tiles need to be the same value. Therefore, the smoothness heuristic just measures the value difference between neighboring tiles, trying to minimize this count.

A commenter on Hacker News gave an interesting formalization of this idea in terms of graph theory.

Here's a screenshot of a perfectly smooth grid, courtesy of this excellent parody fork.

Free Tiles

And finally, there is a penalty for having too few free tiles, since options can quickly run out when the game board gets too cramped.

And that's it! Searching through the game space while optimizing these criteria yields remarkably good performance. One advantage to using a generalized approach like this rather than an explicitly coded move strategy is that the algorithm can often find interesting and unexpected solutions. If you watch it run, it will often make surprising but effective moves, like suddenly switching which wall or corner it's building up against.

Edit:

Here's a demonstration of the power of this approach. I uncapped the tile values (so it kept going after reaching 2048) and here is the best result after eight trials.

Yes, that's a 4096 alongside a 2048. =) That means it achieved the elusive 2048 tile three times on the same board.

To bypass google's check, which is what you really want, simply remove the extensions from the file when you send it, and add them back after you download it. For example:

• tar czvf file.tar.gz directory
• mv file.tar.gz filetargz
• [send filetargz via gmail]
• [download filetargz]
• [rename filetargz to file.tar.gz and open]

input[type=checkbox]
{
  /* Double-sized Checkboxes */
  -ms-transform: scale(2); /* IE */
  -moz-transform: scale(2); /* FF */
  -webkit-transform: scale(2); /* Safari and Chrome */
  -o-transform: scale(2); /* Opera */
  padding: 10px;
}

try this

sudo chmod -R 0777 /opt/lampp/htdocs/testproject

Yes the culprit is definitely word-wrapping. When I tested your two programs, NetBeans IDE 8.2 gave me the following result.

1. First Matrix: O and # = 6.03 seconds
2. Second Matrix: O and B = 50.97 seconds

Looking at your code closely you have used a line break at the end of first loop. But you didn't use any line break in second loop. So you are going to print a word with 1000 characters in the second loop. That causes a word-wrapping problem. If we use a non-word character " " after B, it takes only 5.35 seconds to compile the program. And If we use a line break in the second loop after passing 100 values or 50 values, it takes only 8.56 seconds and 7.05 seconds respectively.

Random r = new Random();
for (int i = 0; i < 1000; i++) {
    for (int j = 0; j < 1000; j++) {
        if(r.nextInt(4) == 0) {
            System.out.print("O");
        } else {
            System.out.print("B");
        }
        if(j%100==0){               //Adding a line break in second loop      
            System.out.println();
        }                    
    }
    System.out.println("");                
}

Another advice is that to change settings of NetBeans IDE. First of all, go to NetBeans Tools and click Options. After that click Editor and go to Formatting tab. Then select Anywhere in Line Wrap Option. It will take almost 6.24% less time to compile the program.

You can do the HTML parsing but it is not at all recommended instead ask the website owners to provide web services then you can parse that information.

Here's a simple example of how to load JSON data into an Angular model.

I have a JSON 'GET' web service which returns a list of Customer details, from an online copy of Microsoft's Northwind SQL Server database.

http://www.iNorthwind.com/Service1.svc/getAllCustomers

It returns some JSON data which looks like this:

{ 
    "GetAllCustomersResult" : 
        [
            {
              "CompanyName": "Alfreds Futterkiste",
              "CustomerID": "ALFKI"
            },
            {
              "CompanyName": "Ana Trujillo Emparedados y helados",
              "CustomerID": "ANATR"
            },
            {
              "CompanyName": "Antonio Moreno Taquería",
              "CustomerID": "ANTON"
            }
        ]
    }

..and I want to populate a drop down list with this data, to look like this...

I want the text of each item to come from the "CompanyName" field, and the ID to come from the "CustomerID" fields.

How would I do it ?

My Angular controller would look like this:

function MikesAngularController($scope, $http) {

    $scope.listOfCustomers = null;

    $http.get('http://www.iNorthwind.com/Service1.svc/getAllCustomers')
         .success(function (data) {
             $scope.listOfCustomers = data.GetAllCustomersResult;
         })
         .error(function (data, status, headers, config) {
             //  Do some error handling here
         });
}

... which fills a "listOfCustomers" variable with this set of JSON data.

Then, in my HTML page, I'd use this:

<div ng-controller='MikesAngularController'>
    <span>Please select a customer:</span>
    <select ng-model="selectedCustomer" ng-options="customer.CustomerID as customer.CompanyName for customer in listOfCustomers" style="width:350px;"></select>
</div>

And that's it. We can now see a list of our JSON data on a web page, ready to be used.

The key to this is in the "ng-options" tag:

customer.CustomerID as customer.CompanyName for customer in listOfCustomers

It's a strange syntax to get your head around !

When the user selects an item in this list, the "$scope.selectedCustomer" variable will be set to the ID (the CustomerID field) of that Customer record.

The full script for this example can be found here:

Your question is very poorly worded. Your code (sort of) already does what you want. What exactly are you confused about? x.numpy() answer the original title of your question:

Pytorch tensor to numpy array

you need improve your question starting with your title.

Anyway, just in case this is useful to others. You might need to call detach for your code to work. e.g.

RuntimeError: Can't call numpy() on Variable that requires grad.

So call .detach(). Sample code:

# creating data and running through a nn and saving it

import torch
import torch.nn as nn

from pathlib import Path
from collections import OrderedDict

import numpy as np

path = Path('~/data/tmp/').expanduser()
path.mkdir(parents=True, exist_ok=True)

num_samples = 3
Din, Dout = 1, 1
lb, ub = -1, 1

x = torch.torch.distributions.Uniform(low=lb, high=ub).sample((num_samples, Din))

f = nn.Sequential(OrderedDict([
    ('f1', nn.Linear(Din,Dout)),
    ('out', nn.SELU())
]))
y = f(x)

# save data
y.numpy()
x_np, y_np = x.detach().cpu().numpy(), y.detach().cpu().numpy()
np.savez(path / 'db', x=x_np, y=y_np)

print(x_np)

cpu goes after detach. See: https://discuss.pytorch.org/t/should-it-really-be-necessary-to-do-var-detach-cpu-numpy/35489/5

Also I won't make any comments on the slicking since that is off topic and that should not be the focus of your question. See this:

Understanding slice notation

In C, it is a common idiom to zero out the memory for a struct using memset:

struct x myStruct;
memset(&myStruct, 0, sizeof(myStruct));

Technically speaking, I don't believe that this is portable because it assumes that the NULL pointer on a machine is represented by the integer value 0, but it's used widely because on most machines this is the case.

If you move from C to C++, be careful not to use this technique on every object. C++ only makes this legal on objects with no member functions and no inheritance.

I had same issue and below is resolved.

Old Service Code:

@Injectable()

Updated working Service Code:

@Injectable({
  providedIn: 'root'
})

You can simply 'add' the arrays:

>> $a = array(1, 2, 3);
array (
  0 => 1,
  1 => 2,
  2 => 3,
)
>> $b = array("a" => 1, "b" => 2, "c" => 3)
array (
  'a' => 1,
  'b' => 2,
  'c' => 3,
)
>> $a + $b
array (
  0 => 1,
  1 => 2,
  2 => 3,
  'a' => 1,
  'b' => 2,
  'c' => 3,
)

You've simply got it backwards. Specifying a minimum width would make the select menu always be at least that width, so it will continue expanding to 90% no matter what the window size is, also being at least the size of its longest option.

You need to use max-width instead. This way, it will let the select menu expand to its longest option, but if that expands past your set maximum of 90% width, crunch it down to that width.

A perfect working code..

    <script>
    var objConnection = new ActiveXObject("adodb.connection");
    var strConn = "driver={sql server};server=QITBLRQIPL030;database=adventureworks;uid=sa;password=12345";
    objConnection.Open(strConn);
    var rs = new ActiveXObject("ADODB.Recordset");
    var strQuery = "SELECT * FROM  Person.Address";
    rs.Open(strQuery, objConnection);
    rs.MoveFirst();
    while (!rs.EOF) {
        document.write(rs.fields(0) + "&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;");
        document.write(rs.fields(1) + "&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;");
        document.write(rs.fields(2) + "&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;    ");
        document.write(rs.fields(3) + "&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;    ");
        document.write(rs.fields(4) + "<br/>");
        rs.movenext();
    }
</script>

You probably want to use "eq" instead of "==". If you worry about some edge cases you may also want to check for undefined:

if (not defined $str) {

# this variable is undefined

}

inside your <div></div> element you can call the $(document).ready(function(){}); execute a command, something like

<div id="div1">
    <script>
        $(document).ready(function(){
         //do something
        });
    </script>
</div>

and you can do the same to other divs that you have. this was suitable if you loading your div via partial view

Delete

public static void deleteRecursive(File fileOrDirectory) {

 if (fileOrDirectory.isDirectory())
    for (File child : fileOrDirectory.listFiles())
        deleteRecursive(child);

    fileOrDirectory.delete();

    }

check this link for above function.

Copy

public static void copyDirectoryOneLocationToAnotherLocation(File sourceLocation, File targetLocation)
    throws IOException {

if (sourceLocation.isDirectory()) {
    if (!targetLocation.exists()) {
        targetLocation.mkdir();
    }

    String[] children = sourceLocation.list();
    for (int i = 0; i < sourceLocation.listFiles().length; i++) {

        copyDirectoryOneLocationToAnotherLocation(new File(sourceLocation, children[i]),
                new File(targetLocation, children[i]));
    }
} else {

    InputStream in = new FileInputStream(sourceLocation);

    OutputStream out = new FileOutputStream(targetLocation);

    // Copy the bits from instream to outstream
    byte[] buf = new byte[1024];
    int len;
    while ((len = in.read(buf)) > 0) {
        out.write(buf, 0, len);
    }
    in.close();
    out.close();
}

}

Move

move is nothing just copy the folder one location to another then delete the folder thats it

manifest

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

This worked for me

textview.setTypeface(textview.getTypeface(), Typeface.BOLD);

or

textview.setTypeface(Typeface.DEFAULT_BOLD);

id is of primitive type int and not an Object. You cannot call methods on a primitive as you are doing here :

id.equals

Try replacing this:

        if (id.equals(list[pos].getItemNumber())){ //Getting error on "equals"

with

        if (id == list[pos].getItemNumber()){ //Getting error on "equals"

Swift 5 Use button.setTitle()

1. If using storyboards, make a IBOutlet reference.

@IBOutlet weak var button: UIButton!

2. Call setTitle on the button followed by the text and the state.

button.setTitle("Button text here", forState: .normal)

Check out history.js. There is a html 5 statechange event and you can listen to it.

I think I have found a better way. You don't have to put attributes into your classes. I've made two methods for serialization and deserialization which take generic list as parameter.

Take a look (it works for me):

private void SerializeParams<T>(XDocument doc, List<T> paramList)
    {
        System.Xml.Serialization.XmlSerializer serializer = new System.Xml.Serialization.XmlSerializer(paramList.GetType());

        System.Xml.XmlWriter writer = doc.CreateWriter();

        serializer.Serialize(writer, paramList);

        writer.Close();           
    }

private List<T> DeserializeParams<T>(XDocument doc)
    {
        System.Xml.Serialization.XmlSerializer serializer = new System.Xml.Serialization.XmlSerializer(typeof(List<T>));

        System.Xml.XmlReader reader = doc.CreateReader();

        List<T> result = (List<T>)serializer.Deserialize(reader);
        reader.Close();

        return result;
    }

So you can serialize whatever list you want! You don't need to specify the list type every time.

        List<AssemblyBO> list = new List<AssemblyBO>();
        list.Add(new AssemblyBO());
        list.Add(new AssemblyBO() { DisplayName = "Try", Identifier = "243242" });
        XDocument doc = new XDocument();
        SerializeParams<T>(doc, list);
        List<AssemblyBO> newList = DeserializeParams<AssemblyBO>(doc);

If you want to export just single table, or subset of data from some table, you can do it directly from result window:

1. Click export button:

2. Change Save as type to "SQL Insert statements"

I'm a big fan of using EPPlus to perform these types of actions. EPPlus is a library you can reference in your project and easily create/modify spreadsheets on a server. I use it for any project that requires an export function.

Here's a nice blog entry that shows how to use the library, though the library itself should come with some samples that explain how to use it.

Third party libraries are a lot easier to use than Microsoft COM objects, in my opinion. I would suggest giving it a try.

I want to mention something that caught me first when I was trying to adapt a SpriteKit-based app to avoid the round edges and "notch" of the new iPhone X, as suggested by the latest Human Interface Guidelines: The new property safeAreaLayoutGuide of UIView needs to be queried after the view has been added to the hierarchy (for example, on -viewDidAppear:) in order to report a meaningful layout frame (otherwise, it just returns the full screen size).

From the property's documentation:

The layout guide representing the portion of your view that is unobscured by bars and other content. When the view is visible onscreen, this guide reflects the portion of the view that is not covered by navigation bars, tab bars, toolbars, and other ancestor views. (In tvOS, the safe area reflects the area not covered the screen's bezel.) If the view is not currently installed in a view hierarchy, or is not yet visible onscreen, the layout guide edges are equal to the edges of the view.

(emphasis mine)

If you read it as early as -viewDidLoad:, the layoutFrame of the guide will be {{0, 0}, {375, 812}} instead of the expected {{0, 44}, {375, 734}}

As of April 2018, you can stop infinite loops in Chrome:

1. Open the Sources panel in Developer Tools (Ctrl+Shift+I**).
2. Click the Pause button to Pause script execution.

Also note the shortcut keys: F8 and Ctrl+\

$.getJSON("http://jsonip.com?callback=?", function (data) {
    alert("Your ip: " + data.ip);
});

Until version 4.6

The dash type of a linestyle is given by the linetype, which does also select the line color unless you explicitely set an other one with linecolor.

However, the support for dashed lines depends on the selected terminal:

1. Some terminals don't support dashed lines, like png (uses libgd)
2. Other terminals, like pngcairo, support dashed lines, but it is disables by default. To enable it, use set termoption dashed, or set terminal pngcairo dashed ....
3. The exact dash patterns differ between terminals. To see the defined linetype, use the test command:

Running

set terminal pngcairo dashed
set output 'test.png'
test
set output

gives:

whereas, the postscript terminal shows different dash patterns:

set terminal postscript eps color colortext
set output 'test.eps'
test
set output

Version 5.0

Starting with version 5.0 the following changes related to linetypes, dash patterns and line colors are introduced:

• A new dashtype parameter was introduced:

  To get the predefined dash patterns, use e.g.

  plot x dashtype 2
  

  You can also specify custom dash patterns like

  plot x dashtype (3,5,10,5),\
       2*x dashtype '.-_'
  

• The terminal options dashed and solid are ignored. By default all lines are solid. To change them to dashed, use e.g.

  set for [i=1:8] linetype i dashtype i
  

• The default set of line colors was changed. You can select between three different color sets with set colorsequence default|podo|classic:

The browser will execute the scripts in the order it finds them. If you call an external script, it will block the page until the script has been loaded and executed.

To test this fact:

// file: test.php
sleep(10);
die("alert('Done!');");

// HTML file:
<script type="text/javascript" src="test.php"></script>

Dynamically added scripts are executed as soon as they are appended to the document.

To test this fact:

<!DOCTYPE HTML>
<html>
<head>
    <title>Test</title>
</head>
<body>
    <script type="text/javascript">
        var s = document.createElement('script');
        s.type = "text/javascript";
        s.src = "link.js"; // file contains alert("hello!");
        document.body.appendChild(s);
        alert("appended");
    </script>
    <script type="text/javascript">
        alert("final");
    </script>
</body>
</html>

Order of alerts is "appended" -> "hello!" -> "final"

If in a script you attempt to access an element that hasn't been reached yet (example: <script>do something with #blah</script><div id="blah"></div>) then you will get an error.

Overall, yes you can include external scripts and then access their functions and variables, but only if you exit the current <script> tag and start a new one.
