The best code is no code, and with stored procedures you have to write at least some code in the database and code in the application to call it , whereas with LINQ to SQL or LINQ to Entities, you don't have to write any additional code beyond any other LINQ query aside from instantiating a context object.

I know it's old, but you can:

• Create a service layer
• Move method there
• Call method in both controllers

I would like to add one more reliable way using UsedRange to find the last used row:

lastRow = Sheet1.UsedRange.Row + Sheet1.UsedRange.Rows.Count - 1

Similarly to find the last used column you can see this

Result in Immediate Window:

?Sheet1.UsedRange.Row+Sheet1.UsedRange.Rows.Count-1
 21 

limit option, e.g.:

svn log --limit 4

svn log -l 4

Only the last 4 entries

select * from sys.tables
order by schema_id      --comments: order by 'schema_id' to get the 'tables' in 'object explorer order'
go

static void Main(string[] args)
        {
            Console.WriteLine("Enter a string to check pallingdrome i.e startreverse is same");
            string str = Convert.ToString( Console.ReadLine());

            char[] arr = str.ToCharArray();
            var strLength = arr.Length-1;
            string newStr = "";
            for (var i= strLength; i < arr.Length; i--)
            {

                newStr = newStr + Convert.ToString(arr[i]);
                if(i==0)
                {
                    break;
                }
            }
            if(str==newStr)
            {
                Console.WriteLine("Entered key is Palindrome");
                Console.ReadLine();
            }
            else
            {
                Console.WriteLine("Entered key is not Palindrome");
                Console.ReadLine();
            }

        }

If your application has minimum sdk version 16 then you can use finishAffinity()

Finish this activity as well as all activities immediately below it in the current task that have the same affinity.

This is work for me In Top Payment screen remove all back-stack activits,

@Override
public void onBackPressed() {
         finishAffinity();
        startActivity(new Intent(PaymentDoneActivity.this,Home.class));
    }

I know this is kind of old and has been marked as answers with 147 up votes, but there is something else to consider.

You can have all the model errors, the property named and string.Empty keys alike, be shown in the ValidationSummary if you need to. There is an overload in the ValidationSummary that will do this.

    //   excludePropertyErrors:
    //   true to have the summary display model-level errors only, or false to have
    //   the summary display all errors.
    public static MvcHtmlString ValidationSummary(this HtmlHelper htmlHelper, bool excludePropertyErrors);

All the above answers technically answer the asker's question, but just thought I'd point out a case where you might encounter problems.

If you declare your struct like this:

typedef struct{
int x;
foo(){};
} foo;

You will have problems trying to declare a constructor. This is of course because you haven't actually declared a struct named "foo", you've created an anonymous struct and assigned it the alias "foo". This also means you will not be able to use "foo" with a scoping operator in a cpp file:

foo.h:

typedef struct{
int x;
void myFunc(int y);
} foo;

foo.cpp:

//<-- This will not work because the struct "foo" was never declared.
void foo::myFunc(int y)
{
  //do something...
}

To fix this, you must either do this:

struct foo{
int x;
foo(){};
};

or this:

typedef struct foo{
int x;
foo(){};
} foo;

Where the latter creates a struct called "foo" and gives it the alias "foo" so you don't have to use the struct keyword when referencing it.

You can mix C++ with Objective-C if you do it carefully. There are a few caveats but generally speaking they can be mixed. If you want to keep them separate, you can set up a standard C wrapper function that gives the Objective-C object a usable C-style interface from non-Objective-C code (pick better names for your files, I have picked these names for verbosity):

MyObject-C-Interface.h

#ifndef __MYOBJECT_C_INTERFACE_H__
#define __MYOBJECT_C_INTERFACE_H__

// This is the C "trampoline" function that will be used
// to invoke a specific Objective-C method FROM C++
int MyObjectDoSomethingWith (void *myObjectInstance, void *parameter);
#endif

MyObject.h

#import "MyObject-C-Interface.h"

// An Objective-C class that needs to be accessed from C++
@interface MyObject : NSObject
{
    int someVar;
}

// The Objective-C member function you want to call from C++
- (int) doSomethingWith:(void *) aParameter;
@end

MyObject.mm

#import "MyObject.h"

@implementation MyObject

// C "trampoline" function to invoke Objective-C method
int MyObjectDoSomethingWith (void *self, void *aParameter)
{
    // Call the Objective-C method using Objective-C syntax
    return [(id) self doSomethingWith:aParameter];
}

- (int) doSomethingWith:(void *) aParameter
{
    // The Objective-C function you wanted to call from C++.
    // do work here..
    return 21 ; // half of 42
}
@end

MyCPPClass.cpp

#include "MyCPPClass.h"
#include "MyObject-C-Interface.h"

int MyCPPClass::someMethod (void *objectiveCObject, void *aParameter)
{
    // To invoke an Objective-C method from C++, use
    // the C trampoline function
    return MyObjectDoSomethingWith (objectiveCObject, aParameter);
}

The wrapper function does not need to be in the same .m file as the Objective-C class, but the file that it does exist in needs to be compiled as Objective-C code. The header that declares the wrapper function needs to be included in both CPP and Objective-C code.

(NOTE: if the Objective-C implementation file is given the extension ".m" it will not link under Xcode. The ".mm" extension tells Xcode to expect a combination of Objective-C and C++, i.e., Objective-C++.)

You can implement the above in an Object-Orientented manner by using the PIMPL idiom. The implementation is only slightly different. In short, you place the wrapper functions (declared in "MyObject-C-Interface.h") inside a class with a (private) void pointer to an instance of MyClass.

MyObject-C-Interface.h (PIMPL)

#ifndef __MYOBJECT_C_INTERFACE_H__
#define __MYOBJECT_C_INTERFACE_H__

class MyClassImpl
{
public:
    MyClassImpl ( void );
    ~MyClassImpl( void );

    void init( void );
    int  doSomethingWith( void * aParameter );
    void logMyMessage( char * aCStr );

private:
    void * self;
};

#endif

Notice the wrapper methods no longer require the void pointer to an instance of MyClass; it is now a private member of MyClassImpl. The init method is used to instantiate a MyClass instance;

MyObject.h (PIMPL)

#import "MyObject-C-Interface.h"

@interface MyObject : NSObject
{
    int someVar;
}

- (int)  doSomethingWith:(void *) aParameter;
- (void) logMyMessage:(char *) aCStr;

@end

MyObject.mm (PIMPL)

#import "MyObject.h"

@implementation MyObject

MyClassImpl::MyClassImpl( void )
    : self( NULL )
{   }

MyClassImpl::~MyClassImpl( void )
{
    [(id)self dealloc];
}

void MyClassImpl::init( void )
{    
    self = [[MyObject alloc] init];
}

int MyClassImpl::doSomethingWith( void *aParameter )
{
    return [(id)self doSomethingWith:aParameter];
}

void MyClassImpl::logMyMessage( char *aCStr )
{
    [(id)self doLogMessage:aCStr];
}

- (int) doSomethingWith:(void *) aParameter
{
    int result;

    // ... some code to calculate the result

    return result;
}

- (void) logMyMessage:(char *) aCStr
{
    NSLog( aCStr );
}

@end

Notice that MyClass is instantiated with a call to MyClassImpl::init. You could instantiate MyClass in MyClassImpl's constructor, but that generally isn't a good idea. The MyClass instance is destructed from MyClassImpl's destructor. As with the C-style implementation, the wrapper methods simply defer to the respective methods of MyClass.

MyCPPClass.h (PIMPL)

#ifndef __MYCPP_CLASS_H__
#define __MYCPP_CLASS_H__

class MyClassImpl;

class MyCPPClass
{
    enum { cANSWER_TO_LIFE_THE_UNIVERSE_AND_EVERYTHING = 42 };
public:
    MyCPPClass ( void );
    ~MyCPPClass( void );

    void init( void );
    void doSomethingWithMyClass( void );

private:
    MyClassImpl * _impl;
    int           _myValue;
};

#endif

MyCPPClass.cpp (PIMPL)

#include "MyCPPClass.h"
#include "MyObject-C-Interface.h"

MyCPPClass::MyCPPClass( void )
    : _impl ( NULL )
{   }

void MyCPPClass::init( void )
{
    _impl = new MyClassImpl();
}

MyCPPClass::~MyCPPClass( void )
{
    if ( _impl ) { delete _impl; _impl = NULL; }
}

void MyCPPClass::doSomethingWithMyClass( void )
{
    int result = _impl->doSomethingWith( _myValue );
    if ( result == cANSWER_TO_LIFE_THE_UNIVERSE_AND_EVERYTHING )
    {
        _impl->logMyMessage( "Hello, Arthur!" );
    }
    else
    {
        _impl->logMyMessage( "Don't worry." );
    }
}

You now access calls to MyClass through a private implementation of MyClassImpl. This approach can be advantageous if you were developing a portable application; you could simply swap out the implementation of MyClass with one specific to the other platform ... but honestly, whether this is a better implementation is more a matter of taste and needs.

I've tested all given regexes but unfortunately none of them pass those tests:

    String []goodNums={"3","-3","0","0.0","1.0","0.1"};
    String []badNums={"001","-00.2",".3","3.","a",""," ","-"," -1","--1","-.1","-0", "2..3", "2-", "2...3", "2.4.3", "5-6-7"};

Here is the best I wrote that pass all those tests:

"^(-?0[.]\\d+)$|^(-?[1-9]+\\d*([.]\\d+)?)$|^0$"

I wrote up a HOWTO for VST development on C++ with Visual Studio awhile back which details the steps necessary to create a basic plugin for the Windows platform (the Mac version of this article is forthcoming). On Windows, a VST plugin is just a normal DLL, but there are a number of "gotchas", and you need to build the plugin using some specific compiler/linker switches or else it won't be recognized by some hosts.

As for the Mac, a VST plugin is just a bundle with the .vst extension, though there are also a few settings which must be configured correctly in order to generate a valid plugin. You can also download a set of Xcode VST plugin project templates I made awhile back which can help you to write a working plugin on that platform.

As for AudioUnits, Apple has provided their own project templates which are included with Xcode. Apple also has very good tutorials and documentation online:

• Audio Unit Programming Guide

I would also highly recommend checking out the Juce Framework, which has excellent support for creating cross-platform VST/AU plugins. If you're going open-source, then Juce is a no-brainer, but you will need to pay licensing fees for it if you plan on releasing your work without source code.

FWIW, @SergeyL's answer is great, but here is a slight variant for testing. Note the change in logical or to logical and.

main.c has a main wrapper like this:

#if !defined(TEST_SPI) && !defined(TEST_SERIAL) && !defined(TEST_USB)
int main(int argc, char *argv[]) {
  // the true main() routine.
}

spi.c, serial.c and usb.c have main wrappers for their respective test code like this:

#ifdef TEST_USB
int main(int argc, char *argv[]) {
  // the  main() routine for testing the usb code.
}

config.h Which is included by all the c files has an entry like this:

// Uncomment below to test the serial
//#define TEST_SERIAL


// Uncomment below to test the spi code
//#define TEST_SPI

// Uncomment below to test the usb code
#define TEST_USB

JVM

The Java Virtual Machine (JVM) is the virtual machine that runs the Java bytecodes. The JVM doesn't understand Java source code; that's why you need compile your *.java files to obtain *.class files that contain the bytecodes understood by the JVM. It's also the entity that allows Java to be a "portable language" (write once, run anywhere). Indeed, there are specific implementations of the JVM for different systems (Windows, Linux, macOS, see the Wikipedia list), the aim is that with the same bytecodes they all give the same results.

JDK and JRE

To explain the difference between JDK and JRE, the best is to read the Oracle documentation and consult the diagram:

Java Runtime Environment (JRE)

The Java Runtime Environment (JRE) provides the libraries, the Java Virtual Machine, and other components to run applets and applications written in the Java programming language. In addition, two key deployment technologies are part of the JRE: Java Plug-in, which enables applets to run in popular browsers; and Java Web Start, which deploys standalone applications over a network. It is also the foundation for the technologies in the Java 2 Platform, Enterprise Edition (J2EE) for enterprise software development and deployment. The JRE does not contain tools and utilities such as compilers or debuggers for developing applets and applications.

Java Development Kit (JDK)

The JDK is a superset of the JRE, and contains everything that is in the JRE, plus tools such as the compilers and debuggers necessary for developing applets and applications.

Note that Oracle is not the only one to provide JDKs.

OpenJDK

OpenJDK is an open-source implementation of the JDK and the base for the Oracle JDK. There is almost no difference between the Oracle JDK and the OpenJDK.

The differences are stated in this blog:

Q: What is the difference between the source code found in the OpenJDK repository, and the code you use to build the Oracle JDK?

A: It is very close - our build process for Oracle JDK releases builds on OpenJDK 7 by adding just a couple of pieces, like the deployment code, which includes Oracle's implementation of the Java Plugin and Java WebStart, as well as some closed source third party components like a graphics rasterizer, some open source third party components, like Rhino, and a few bits and pieces here and there, like additional documentation or third party fonts. Moving forward, our intent is to open source all pieces of the Oracle JDK except those that we consider commercial features such as JRockit Mission Control (not yet available in Oracle JDK), and replace encumbered third party components with open source alternatives to achieve closer parity between the code bases.

Update for JDK 11 - An article from Donald Smith try to disambiguate the difference between Oracle JDK and Oracle's OpenJDK : https://blogs.oracle.com/java-platform-group/oracle-jdk-releases-for-java-11-and-later

If you think of an object as being similar to a noun, then a method is similar to a verb. Use a method right after an object (i.e. a string or a list) to apply a method's action to it.

Default escape character in Java is '\'.
However, Java properties file has format key=value, it should be considering everything after the first equal as value.

just remove and reDownload wrapper gradle.

Mac Home/.gradle/wrapper/dists/

remove gradle version and sync gradle in project and run project.

Your code is fine. What you are seeing is a linker issue.

If you put your code in a single file like this:

#include <iostream>
#include <string>

using namespace std;

string trim(const string& str)
{
    size_t first = str.find_first_not_of(' ');
    if (string::npos == first)
    {
        return str;
    }
    size_t last = str.find_last_not_of(' ');
    return str.substr(first, (last - first + 1));
}

int main() {
    string s = "abc ";
    cout << trim(s);

}

then do g++ test.cc and run a.out, you will see it works.

You should check if the file that contains the trim function is included in the link stage of your compilation process.

If this error occurs while using Material UI <Typography> https://material-ui.com/api/typography/, then you can easily change the <p> to a <span> by changing the value of the component attribute of the <Typography> element :

<Typography component={'span'} variant={'body2'}>

According to the typography docs:

component : The component used for the root node. Either a string to use a DOM element or a component. By default, it maps the variant to a good default headline component.

So Typography is picking <p> as a sensible default, which you can change. May come with side effects ... worked for me.

We can use drush command also to check logs drush watchdog-show it will show recent 10 messages.

or if we want to continue showing logs with more information we can user

drush watchdog-show --tail --full.

Your comment to cletus' (correct) answer implies that there are multiple Maven settings files involved.

Maven always uses either one or two settings files. The global settings defined in (${M2_HOME}/conf/settings.xml) is always required. The user settings file (defined in ${user.home}/.m2/settings.xml) is optional. Any settings defined in the user settings take precedence over the corresponding global settings.

You can override the location of the global and user settings from the command line, the following example will set the global settings to c:\global\settings.xml and the user settings to c:\user\settings.xml:

mvn install --settings c:\user\settings.xml 
    --global-settings c:\global\settings.xml

Currently there is no property or means to establish what user and global settings files were used from with Maven. To access these values, you would have to modify MavenCli and/or DefaultMavenSettingsBuilder to inject the file locations into the resolved Settings object.

You can use the spread operator:

 <button style={{...styles.panel.button,...styles.panel.backButton}}>Back</button

Create a custom reverseIterable.

compareTo() is called on one object, to compare it to another object. compare() is called on some object to compare two other objects.

The difference is where the logic that does actual comparison is defined.

Just remove the obsolete gems from your Gemfile. If you're talking about Heroku (you didn't mention that) then the slug is compiled each new release, just using the current contents of that file.

Your web.xml ends with <web-app>, but must end with </web-app>

Which by the way is almost literally what the exception tells you.

Try the correct constructor http://docs.oracle.com/javase/7/docs/api/java/math/BigDecimal.html#BigDecimal(java.lang.String)

You can directly instanciate the BigDecimal with the String ;)

Example:

BigDecimal bigDecimalValue= new BigDecimal("0.5");

Simple solution

<?php
   $x = 1;
     for($x = 1; $x < 8; $x++) {
        $x = $x + 1;
       echo $x;
     };    
?>

SELECT
   *
FROM
   primarytable P
WHERE
   NOT EXISTS (SELECT * FROM secondarytable S
     WHERE
         P.PKCol = S.FKCol)

Generally, (NOT) EXISTS is a better choice then (NOT) IN or (LEFT) JOIN

New -> Batch Drawable Import -> Click on Add button -> Select image -> Select Target Resolution, Target Name, Format -> Ok

The two reflection-like solutions I know of from my C++ days are:

1) Use RTTI, which will provide a bootstrap for you to build your reflection-like behaviour, if you are able to get all your classes to derive from an 'object' base class. That class could provide some methods like GetMethod, GetBaseClass etc. As for how those methods work you will need to manually add some macros to decorate your types, which behind the scenes create metadata in the type to provide answers to GetMethods etc.

2) Another option, if you have access to the compiler objects is to use the DIA SDK. If I remember correctly this lets you open pdbs, which should contain metadata for your C++ types. It might be enough to do what you need. This page shows how you can get all base types of a class for example.

Both these solution are a bit ugly though! There is nothing like a bit of C++ to make you appreciate the luxuries of C#.

Good Luck.

You should be able to call print("yo!") since there is a constructor for std::string which takes a const char*. These single argument constructors define implicit conversions from their aguments to their class type (unless the constructor is declared explicit which is not the case for std::string). Have you actually tried to compile this code?

void print(std::string input)
{
    cout << input << endl;
} 
int main()
{
    print("yo");
}

It compiles fine for me in GCC. However, if you declared print like this void print(std::string& input) then it would fail to compile since you can't bind a non-const reference to a temporary (the string would be a temporary constructed from "yo")

I turn on .Net Framework 3.5 and 4.5 Advance Service in Control Panel->Programs and Features->Turn Windows features on or off.it work for me.

Just a piece of advice. Instead of writing

for (int i=0; i=((Main.size())-1); i++) {
   cout << Main[i] << '\n';
}

as suggested above, write a:

for (vector<double>::iterator it=Main.begin(); it!=Main.end(); it++) {
   cout << *it << '\n';
}

to use iterators. If you have C++11 support, you can declare i as auto i=Main.begin() (just a handy shortcut though)

This avoids the nasty one-position-out-of-bound error caused by leaving out a -1 unintentionally.

This is more the Angular way to do it: http://plnkr.co/edit/xYNX47EsYvl4aRuGZmvo?p=preview

1. I added $scope.selectedItem that gets you past your first problem (defaulting the image)
2. I added $scope.setSelectedItem and called it in ng-click. Your final requirements may be different, but using a directive to bind click and change src was overkill, since most of it can be handled with template
3. Notice use of ngSrc to avoid errant server calls on initial load
4. You'll need to adjust some styles to get the image positioned right in the div. If you really need to use background-image, then you'll need a directive like ngSrc that defers setting the background-image style until after real data has loaded.

Default argument values are evaluated at function define-time, but self is an argument only available at function call time. Thus arguments in the argument list cannot refer each other.

It's a common pattern to default an argument to None and add a test for that in code:

def p(self, b=None):
    if b is None:
        b = self.a
    print b

With version 3 of PowerShell you can chain the replace calls together:

 (Get-Content $sourceFile) | ForEach-Object {
    $_.replace('something1', 'something1').replace('somethingElse1', 'somethingElse2')
 } | Set-Content $destinationFile

I believe this is efficient enough... To get a String from an InputStream, I'd call the following method:

public static String getStringFromInputStream(InputStream stream) throws IOException
{
    int n = 0;
    char[] buffer = new char[1024 * 4];
    InputStreamReader reader = new InputStreamReader(stream, "UTF8");
    StringWriter writer = new StringWriter();
    while (-1 != (n = reader.read(buffer))) writer.write(buffer, 0, n);
    return writer.toString();
}

I always use UTF-8. You could, of course, set charset as an argument, besides InputStream.

The key idea is you form a set of the rows you want to remove, and keep the complement of that set.

In R, the complement of a set is given by the '-' operator.

So, assuming the data.frame is called myData:

myData[-c(2, 4, 6), ]   # notice the -

Of course, don't forget to "reassign" myData if you wanted to drop those rows entirely---otherwise, R just prints the results.

myData <- myData[-c(2, 4, 6), ]

You can use aspnet_compiler for this:

C:\Windows\Microsoft.NET\Framework\v2.0.50727\aspnet_compiler -v /Virtual/Application/Path/Or/Path/In/IIS/Metabase -p C:\Path\To\Your\WebProject -f -errorstack C:\Where\To\Put\Compiled\Site

where "/Virtual/Application/Path/Or/Path/In/IIS/Metabase" is something like this: "/MyApp" or "/lm/w3svc2/1/root/"

Also there is a AspNetCompiler Task on MSDN, showing how to integrate aspnet_compiler with MSBuild:

<Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
    <Target Name="PrecompileWeb">
        <AspNetCompiler
            VirtualPath="/MyWebSite"
            PhysicalPath="c:\inetpub\wwwroot\MyWebSite\"
            TargetPath="c:\precompiledweb\MyWebSite\"
            Force="true"
            Debug="true"
        />
    </Target>
</Project>

You need an HTML page to load a JS file.

Added more complex example with "custom validation" on the side of controller http://jsfiddle.net/82PX4/3/

<div class='line' ng-repeat='line in ranges' ng-form='lineForm'>
    low: <input type='text' 
                name='low'
                ng-pattern='/^\d+$/' 
                ng-change="lowChanged(this, $index)" ng-model='line.low' />
    up: <input type='text' 
                name='up'
                ng-pattern='/^\d+$/'
                ng-change="upChanged(this, $index)" 
                ng-model='line.up' />
    <a href ng-if='!$first' ng-click='removeRange($index)'>Delete</a>
    <div class='error' ng-show='lineForm.$error.pattern'>
        Must be a number.
    </div>
    <div class='error' ng-show='lineForm.$error.range'>
        Low must be less the Up.
    </div>
</div>

If you're using a shell, the filepath to the Download (no "s") folder is

/storage/emulated/0/Download

With argparse you could do:

parser.argparse.ArgumentParser()
#parser.add_args here

#sys.argv includes a list of elements starting with the program
if len(sys.argv) < 2:
    parser.print_usage()
    sys.exit(1)

You could use memset, if you sure about the length.

memset(ptr, 0x00, length)

To have the same flexibility in CONCAT_WS as in CONCAT (if you don't want the same separator between every member for instance) use the following:

SELECT CONCAT_WS("",affiliate_name,':',model,'-',ip,... etc)

$('#usersSearch').keyup(function() { // handle keyup event on search input field

    var key = e.which || e.keyCode;  // store browser agnostic keycode

    if(key == 13) 
        $(this).closest('form').submit(); // submit parent form
}

From Save MySQL query results into a text or CSV file:

MySQL provides an easy mechanism for writing the results of a select statement into a text file on the server. Using extended options of the INTO OUTFILE nomenclature, it is possible to create a comma separated value (CSV) which can be imported into a spreadsheet application such as OpenOffice or Excel or any other application which accepts data in CSV format.

Given a query such as

SELECT order_id,product_name,qty FROM orders

which returns three columns of data, the results can be placed into the file /tmp/orders.txt using the query:

SELECT order_id,product_name,qty FROM orders
INTO OUTFILE '/tmp/orders.txt'

This will create a tab-separated file, each row on its own line. To alter this behavior, it is possible to add modifiers to the query:

SELECT order_id,product_name,qty FROM orders
INTO OUTFILE '/tmp/orders.csv'
FIELDS TERMINATED BY ','
ENCLOSED BY '"'
LINES TERMINATED BY '\n'

In this example, each field will be enclosed in double quotes, the fields will be separated by commas, and each row will be output on a new line separated by a newline (\n). Sample output of this command would look like:

"1","Tech-Recipes sock puppet","14.95" "2","Tech-Recipes chef's hat","18.95"

Keep in mind that the output file must not already exist and that the user MySQL is running as has write permissions to the directory MySQL is attempting to write the file to.

Syntax

   SELECT Your_Column_Name
    FROM Your_Table_Name
    INTO OUTFILE 'Filename.csv'
    FIELDS TERMINATED BY ','
    ENCLOSED BY '"'
    LINES TERMINATED BY '\n'

Or you could try to grab the output via the client:

You could try executing the query from the your local client and redirect the output to a local file destination:

mysql -user -pass -e "select cols from table where cols not null" > /tmp/output

Hint: If you don't specify an absoulte path but use something like INTO OUTFILE 'output.csv' or INTO OUTFILE './output.csv', it will store the output file to the directory specified by show variables like 'datadir';.

From the article in JavaWorld

A superficial answer is that Java does not provide anything like C's sizeof(). However, let's consider why a Java programmer might occasionally want it.

A C programmer manages most datastructure memory allocations himself, and sizeof() is indispensable for knowing memory block sizes to allocate. Additionally, C memory allocators like malloc() do almost nothing as far as object initialization is concerned: a programmer must set all object fields that are pointers to further objects. But when all is said and coded, C/C++ memory allocation is quite efficient.

By comparison, Java object allocation and construction are tied together (it is impossible to use an allocated but uninitialized object instance). If a Java class defines fields that are references to further objects, it is also common to set them at construction time. Allocating a Java object therefore frequently allocates numerous interconnected object instances: an object graph. Coupled with automatic garbage collection, this is all too convenient and can make you feel like you never have to worry about Java memory allocation details.

Of course, this works only for simple Java applications. Compared with C/C++, equivalent Java datastructures tend to occupy more physical memory. In enterprise software development, getting close to the maximum available virtual memory on today's 32-bit JVMs is a common scalability constraint. Thus, a Java programmer could benefit from sizeof() or something similar to keep an eye on whether his datastructures are getting too large or contain memory bottlenecks. Fortunately, Java reflection allows you to write such a tool quite easily.

Before proceeding, I will dispense with some frequent but incorrect answers to this article's question. Fallacy: Sizeof() is not needed because Java basic types' sizes are fixed

Yes, a Java int is 32 bits in all JVMs and on all platforms, but this is only a language specification requirement for the programmer-perceivable width of this data type. Such an int is essentially an abstract data type and can be backed up by, say, a 64-bit physical memory word on a 64-bit machine. The same goes for nonprimitive types: the Java language specification says nothing about how class fields should be aligned in physical memory or that an array of booleans couldn't be implemented as a compact bitvector inside the JVM. Fallacy: You can measure an object's size by serializing it into a byte stream and looking at the resulting stream length

The reason this does not work is because the serialization layout is only a remote reflection of the true in-memory layout. One easy way to see it is by looking at how Strings get serialized: in memory every char is at least 2 bytes, but in serialized form Strings are UTF-8 encoded and so any ASCII content takes half as much space

There is no such flag, and having one runs against the Unix philosophy of having each tool perform just one function and perform it well. Spawning compiler processes is conceptually the job of the build system. What you are probably looking for is the -j (jobs) flag to GNU make, a la

make -j4

Or you can use pmake or similar parallel make systems.

static function definitions will mark this symbol as internal. So it will not be visible for linking from outside, but only to functions in the same compilation unit, usually the same file.

You can also get an EntityManager using PersistenceContext or Autowired annotation, but be aware that it will not be thread-safe.

@PersistenceContext
private EntityManager entityManager;

Just add the source and destination folder paths.

It will move all the files and folder from source folder to destination folder.

    File destinationFolder = new File("");
    File sourceFolder = new File("");

    if (!destinationFolder.exists())
    {
        destinationFolder.mkdirs();
    }

    // Check weather source exists and it is folder.
    if (sourceFolder.exists() && sourceFolder.isDirectory())
    {
        // Get list of the files and iterate over them
        File[] listOfFiles = sourceFolder.listFiles();

        if (listOfFiles != null)
        {
            for (File child : listOfFiles )
            {
                // Move files to destination folder
                child.renameTo(new File(destinationFolder + "\\" + child.getName()));
            }

            // Add if you want to delete the source folder 
            sourceFolder.delete();
        }
    }
    else
    {
        System.out.println(sourceFolder + "  Folder does not exists");
    }

Below is a list of hashing algorithm along with its require bit size:

• MD5 = 128-bit hash value.
• SHA1 = 160-bit hash value.
• SHA224 = 224-bit hash value.
• SHA256 = 256-bit hash value.
• SHA384 = 384-bit hash value.
• SHA512 = 512-bit hash value.

Created one sample table with require CHAR(n):

CREATE TABLE tbl_PasswordDataType
(
    ID INTEGER
    ,MD5_128_bit CHAR(32)
    ,SHA_160_bit CHAR(40)
    ,SHA_224_bit CHAR(56)
    ,SHA_256_bit CHAR(64)
    ,SHA_384_bit CHAR(96)
    ,SHA_512_bit CHAR(128)
); 
INSERT INTO tbl_PasswordDataType
VALUES 
(
    1
    ,MD5('SamplePass_WithAddedSalt')
    ,SHA1('SamplePass_WithAddedSalt')
    ,SHA2('SamplePass_WithAddedSalt',224)
    ,SHA2('SamplePass_WithAddedSalt',256)
    ,SHA2('SamplePass_WithAddedSalt',384)
    ,SHA2('SamplePass_WithAddedSalt',512)
);

Another option that may or may not make sense in your case, is to actually have a separate column with pre-lowerscored values of your existing column. This can be populated using the SQLite function LOWER(), and you can then perform matching on this column instead.

Obviously, it adds redundancy and a potential for inconsistency, but if your data is static it might be a suitable option.

#python3

import datetime
print(
    '1: test-{date:%Y-%m-%d_%H:%M:%S}.txt'.format( date=datetime.datetime.now() )
    )

d = datetime.datetime.now()
print( "2a: {:%B %d, %Y}".format(d))

# see the f" to tell python this is a f string, no .format
print(f"2b: {d:%B %d, %Y}")

print(f"3: Today is {datetime.datetime.now():%Y-%m-%d} yay")

1: test-2018-02-14_16:40:52.txt

2a: March 04, 2018

2b: March 04, 2018

3: Today is 2018-11-11 yay

Description:

Using the new string format to inject value into a string at placeholder {}, value is the current time.

Then rather than just displaying the raw value as {}, use formatting to obtain the correct date format.

Update:

Read the Docs for your version of Django. e.g.

https://docs.djangoproject.com/en/1.11/ref/contrib/admin/#admin-overriding-templates https://docs.djangoproject.com/en/2.0/ref/contrib/admin/#admin-overriding-templates https://docs.djangoproject.com/en/3.0/ref/contrib/admin/#admin-overriding-templates

Original answer from 2011:

I had the same issue about a year and a half ago and I found a nice template loader on djangosnippets.org that makes this easy. It allows you to extend a template in a specific app, giving you the ability to create your own admin/index.html that extends the admin/index.html template from the admin app. Like this:

{% extends "admin:admin/index.html" %}

{% block sidebar %}
    {{block.super}}
    <div>
        <h1>Extra links</h1>
        <a href="/admin/extra/">My extra link</a>
    </div>
{% endblock %}

I've given a full example on how to use this template loader in a blog post on my website.

You're right that it involves a loop, but this is, at least, made simple by use of the each() method:

$('.target').each(
    function(){
        // iterate through each of the `.target` elements, and do stuff in here
        // `this` and `$(this)` refer to the current `.target` element
        var images = $(this).find('img'),
            imageWidth = images.width(); // returns the width of the _first_ image
            numImages = images.length;
        $(this).css('width', (imageWidth*numImages));

    });

References:

• css().
• each().
• find().

 List<String> entries;
 private ArrayAdapter<String> categoryAdapter;
 //Your list of entries {Example: <"category1","category2","category3">}
 entries =  new ArrayList<String>();
 categoryAdapter = new ArrayAdapter<String>(ViewBeaconsActivity.this,
                                   android.R.layout.simple_list_item_1, entries);
 //Remove that specific category from the list
 entries.remove(categoryName);
 //Notify the adapter that your dataset has changed.
 categoryAdapter.notifyDataSetChanged();

Try downloading the Java from Apple Support Page: http://support.apple.com/kb/DL1572 if that doesn't work for you or fails to load (very common issue), just follow this link to download and install the Java version you need:

http://support.apple.com/downloads/DL1572/en_US/JavaForOSX2014-001.dmg

That's it.

To get this working in Javascript, I had to do the following:

myString.split(/\s+/g)

I'm a little out of touch with the details of how MySQL deals with nulls, but here's two things to try:

SELECT * FROM match WHERE id NOT IN 
    ( SELECT id FROM email WHERE id IS NOT NULL) ;

SELECT
    m.*
FROM
    match m
    LEFT OUTER JOIN email e ON
        m.id = e.id
        AND e.id IS NOT NULL
WHERE
    e.id IS NULL

The second query looks counter intuitive, but it does the join condition and then the where condition. This is the case where joins and where clauses are not equivalent.

I think you have to define the timestamp column like this

CREATE TABLE t1 
(
    ts TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP
);

See here

I really wanted a pure css solution to this myself, since sprinkling a weighty javascript solution around all of my views seemed like an unpleasant option. Finally found the @media.hover query, which can detect "whether the primary input mechanism allows the user to hover over elements." This avoids touch devices where "hovering" is more of an emulated action than a direct capability of the input device.

So for example, if I have a link:

<a href="/" class="link">Home</a>

Then I can safely style it to only :hover when the device easily supports it with this css:

@media (hover: hover) {
  .link:hover { /* hover styles */ }
}

While most modern browsers support interaction media feature queries, some popular browsers such as IE and Firefox do not. In my case this works fine, since I only intended to support Chrome on desktop and Chrome and Safari on mobile.

I use a Dictionary and because of the repetetiveness and possible missing keys, I quickly patched together a small method:

 private static string GetKey(IReadOnlyDictionary<string, string> dictValues, string keyValue)
 {
     return dictValues.ContainsKey(keyValue) ? dictValues[keyValue] : "";
 }

Calling it:

var entry = GetKey(dictList,"KeyValue1");

Gets the job done.

Adding on to what ADNow said. On the Macintosh:

1. Right click on IntelliJ IDEA 12
2. Click on the Show Package Contents menu option
3. Open the bin folder
4. Open idea.properties

5. Add the line:

   auto.show.quick.doc=true

This is my OK code in QT 4.7:

 //add combobox list 
    QString val;
   ui->startPage->clear();
    val = "http://www.work4blue.com";
    ui->startPage->addItem(tr("Navigation page"),QVariant::fromValue(val));
    val = "https://www.google.com";
    ui->startPage->addItem("www.google.com",QVariant::fromValue(val));
    val = "www.twitter.com";
    ui->startPage->addItem("www.twitter.com",QVariant::fromValue(val));
    val = "https://www.youtube.com";
    ui->startPage->addItem("www.youtube.com",QVariant::fromValue(val));

   // get current value
    qDebug() << "current value"<< 
       ui->startPage->itemData(ui->startPage->currentIndex()).toString();

getLastRowNum() return index of last row.

So if you wants to know total number of row = getLastRowNum() +1.

I hope this will work.

int rowTotal = sheet.getLastRowNum() +1;

I had the exact same problem. Here is the solution that worked for me: simply put your properties file path in the cmd line this way :

-Dlog4j.configuration=<FILE_PATH>  (ex: log4j.properties)

Hope this will help you

For small scripts an optional way to make it readable is to use a variable like this:

awk -v fmt="'%s'\n" '{printf fmt, $1}'

I found it conveninet in a case where I had to produce many times the single-quote character in the output and the \047 were making it totally unreadable

At this stage, Python still has better unicode support

There is no way to "discard" the time component.

DateTime.Today is the same as:

DateTime d = DateTime.Now.Date;

If you only want to display only the date portion, simply do that - use ToString with the format string you need.

For example, using the standard format string "D" (long date format specifier):

d.ToString("D");

The default value of end is \n meaning that after the print statement it will print a new line. So simply stated end is what you want to be printed after the print statement has been executed

Eg: - print ("hello",end=" +") will print hello +

If your project is a single page application, (eg project created by vue init webpack myproject), I found this way is most intuitive and simple:

In main.js

import moment from 'moment'

Vue.prototype.moment = moment

Then in your template, simply use

<span>{{moment(date).format('YYYY-MM-DD')}}</span>

Set below code in RouteConfig.cs in App_Start folder

public static void RegisterRoutes(RouteCollection routes)
{
 routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
 routes.MapRoute(
 name: "Default",
 url: "{controller}/{action}/{id}",
 defaults: new { controller = "Account", action = "Login", id = UrlParameter.Optional });
}

IF still not working then do below steps

Second Way : You simple follow below steps,

1) Right click on your Project

2) Select Properties

3) Select Web option and then Select Specific Page (Controller/View) and then set your login page

Here, Account is my controller and Login is my action method (saved in Account Controller)

Please take a look attached screenshot.

Use the rename script this way:

$ rename 's/^/PRE_/' *

There are no problems with metacharacters or whitespace in filenames.

Since nobody so far felt fit to point out why what you're trying doesn't work:

1. NA == NA doesn't return TRUE, it returns NA (since comparing to undefined values should yield an undefined result).
2. You're trying to call apply on an atomic vector. You can't use apply to loop over the elements in a column.
3. Your subscripts are off - you're trying to give two indices into a$x, which is just the column (an atomic vector).

I'd fix up 3. to get to a$x[is.na(a$x)] <- 0

If at all possible, I would recommend to have four separate fields—Area Code, 3-digit prefix, 4 digit part, extension—so that the user can input each part of the address separately, and you can verify each piece individually. That way you can not only make verification much easier, you can store your phone numbers in a more consistent format in the database.

I think that you'll probably have to use $.ajax() if you want to change the encoding, see the contentType param below (the success and error callbacks assume you have <div id="success"></div> and <div id="error"></div> in the html):

$.ajax({
    type: "POST",
    url: "SomePage.aspx/GetSomeObjects",
    contentType: "application/json; charset=utf-8",
    dataType: "json",
    data: "{id: '" + someId + "'}",
    success: function(json) {
        $("#success").html("json.length=" + json.length);
        itemAddCallback(json);
    },
    error: function (xhr, textStatus, errorThrown) {
        $("#error").html(xhr.responseText);
    }
});

I actually just had to do this about an hour ago, what a coincidence!

If you´re building a new app, put the jsonfile in the right place and make sure it's the jsonfile for that app. Before I realized this, when I clicked the jsonfile, I didn't get the information that wanted.

Go to firebase configurations, download the correct version of google-services.json, and replace the version that didn't work for you. When using the wrong version, you might see the wrong Projectid, storagebucket etc.

            }

Transparency is controlled by the alpha channel (AA in #AARRGGBB). Maximal value (255 dec, FF hex) means fully opaque. Minimum value (0 dec, 00 hex) means fully transparent. Values in between are semi-transparent, i.e. the color is mixed with the background color.

To get a fully transparent color set the alpha to zero. RR, GG and BB are irrelevant in this case because no color will be visible. This means #00FFFFFF ("transparent White") is the same color as #00F0F8FF ("transparent AliceBlue"). To keep it simple one chooses black (#00000000) or white (#00FFFFFF) if the color does not matter.

In the table you linked to you'll find Transparent defined as #00FFFFFF.

I often use something similar to this:

import os
DATA_DIR = os.path.abspath(os.path.join(os.path.dirname(__file__), 'datadir'))

# if you have more paths to set, you might want to shorten this as
here = lambda x: os.path.abspath(os.path.join(os.path.dirname(__file__), x))
DATA_DIR = here('datadir') 

pathjoin = os.path.join
# ...
# later in script
for fn in os.listdir(DATA_DIR):
    f = open(pathjoin(DATA_DIR, fn))
    # ...

The variable

__file__

holds the file name of the script you write that code in, so you can make paths relative to script, but still written with absolute paths. It works quite well for several reasons:

• path is absolute, but still relative
• the project can still be deployed in a relative container

But you need to watch for platform compatibility - Windows' os.pathsep is different than UNIX.

Apart from the fine answers already given, you can also use ceilf(f) == f or floorf(f) == f. Both expressions return true if f is an integer. They also returnfalse for NaNs (NaNs always compare unequal) and true for ±infinity, and don't have the problem with overflowing the integer type used to hold the truncated result, because floorf()/ceilf() return floats.

You may be running out of space either in the partition where the mysql tables are stored (usually /var/lib/mysql) or in where the temporary tables are stored (usually /tmp).

You may want to: - monitor your free space during the index creation. - point the tmpdir MySQL variable to a different location. This requires a server restart.

Just one thing to add to this (although I do think you have already had your question answered by others). In the interests of extensibility (since we all know it will happen at some point) you may want to check out the Composite Pattern This is ideal for working with "Tree-Like Structures"..

Like I said, I know you are only expecting one sub-level, but this could really be useful for you if you later need to extend ^_^

As of version 1.13.1 there is support for Bootstrap 4: https://developer.snapappointments.com/bootstrap-select/

The implementation remains exactly the same as it was in Bootstrap 3:

• add class="selectpicker" and data-live-search="true"to your select
• add data-tokens to your options. The live search will look into these data-token element when performing the search.

This is an example, taken from the site of the link above:

<select class="selectpicker" data-live-search="true">
  <option data-tokens="ketchup mustard">Hot Dog, Fries and a Soda</option>
  <option data-tokens="mustard">Burger, Shake and a Smile</option>
  <option data-tokens="frosting">Sugar, Spice and all things nice</option>
</select>

Live search for the search term 'fro' will only leave the third option visible (because of the data-tokens "frosting").

Don't forget to include the bootstrap-select CDN .css and .js in your project. I am very glad to see this live search become available again, because it comes in very handy when presenting large dropdown lists to the user.

This is an old question, but since I spent the last few weeks trying to figure it out on my own:

1. OpenCL support for Theano is hit and miss. They added a libgpuarray back-end which appears to still be buggy (i.e., the process runs on the GPU but the answer is wrong--like 8% accuracy on MNIST for a DL model that gets ~95+% accuracy on CPU or nVidia CUDA). Also because ~50-80% of the performance boost on the nVidia stack comes from the CUDNN libraries now, OpenCL will just be left in the dust. (SEE BELOW!) :)
2. ROCM appears to be very cool, but the documentation (and even a clear declaration of what ROCM is/what it does) is hard to understand. They're doing their best, but they're 4+ years behind. It does NOT NOT NOT work on an RX550 (as of this writing). So don't waste your time (this is where 1 of the weeks went :) ). At first, it appears ROCM is a new addition to the driver set (replacing AMDGPU-Pro, or augmenting it), but it is in fact a kernel module and set of libraries that essentially replace AMDGPU-Pro. (Think of this as the equivalent of Nvidia-381 driver + CUDA some libraries kind of). https://rocm.github.io/dl.html (Honestly I still haven't tested the performance or tried to get it to work with more recent Mesa drivers yet. I will do that sometime.
3. Add MiOpen to ROCM, and that is essentially CUDNN. They also have some pretty clear guides for migrating. But better yet.
4. They created "HIP" which is an automagical translator from CUDA/CUDNN to MiOpen. It seems to work pretty well since they lined the API's up directly to be translatable. There are concepts that aren't perfect maps, but in general it looks good.

Now, finally, after 3-4 weeks of trying to figure out OpenCL, etc, I found this tutorial to help you get started quickly. It is a step-by-step for getting hipCaffe up and running. Unlike nVidia though, please ensure you have supported hardware!!!! https://rocm.github.io/hardware.html. Think you can get it working without their supported hardware? Good luck. You've been warned. Once you have ROCM up and running (AND RUN THE VERIFICATION TESTS), here is the hipCaffe tutorial--if you got ROCM up you'll be doing an MNIST validation test within 10 minutes--sweet! https://rocm.github.io/ROCmHipCaffeQuickstart.html

For my project, the problem turned out to be a circular reference created by the require() calls:

y.js:
var x = require("./x.js");
var y = function() { console.log("result is " + x(); }
module.exports = y;

x.js:
var y = require("./y.js");
var my_y = new y(); // <- TypeError: y is not a constructor
var x = function() { console.log("result is " + my_y; }
module.exports = x;

The reason is that when it is attempting to initialize y, it creates a temporary "y" object (not class, object!) in the dependency system that is somehow not yet a constructor. Then, when x.js is finished being defined, it can continue making y a constructor. Only, x.js has an error in it where it tries to use the non-constructor y.

Flutter Launcher Icons has been designed to help quickly generate launcher icons for both Android and iOS: https://pub.dartlang.org/packages/flutter_launcher_icons

• Add the package to your pubspec.yaml file (within your Flutter project) to use it
• Within pubspec.yaml file specify the path of the icon you wish to use for the app and then choose whether you want to use the icon for the iOS app, Android app or both.
• Run the package
• Voila! The default launcher icons have now been replaced with your custom icon

I'm hoping to add a video to the GitHub README to demonstrate it

Video showing how to run the tool can be found here.

If anyone wants to suggest improvements / report bugs, please add it as an issue on the GitHub project.

Update: As of Wednesday 24th January 2018, you should be able to create new icons without overriding the old existing launcher icons in your Flutter project.

Update 2: As of v0.4.0 (8th June 2018) you can specify one image for your Android icon and a separate image for your iOS icon.

Update 3: As of v0.5.2 (20th June 2018) you can now add adaptive launcher icons for the Android app of your Flutter project

These are terms usually used when describing a "FIFO" queue, that is "first in, first out". This works like a line. You decide to go to the movies. There is a long line to buy tickets, you decide to get into the queue to buy tickets, that is "Enqueue". at some point you are at the front of the line, and you get to buy a ticket, at which point you leave the line, that is "Dequeue".

There is much simpler way:

using System;
using System.Collections.Generic;
....
var caseInsensitiveDictionary = new Dictionary<string, string>(StringComparer.OrdinalIgnoreCase);

%timeit is an ipython magic function, which can be used to time a particular piece of code (A single execution statement, or a single method).

    %timeit [-n<N> -r<R> [-t|-c] -q -p<P> -o] statement

To use it, for example if we want to find out whether using xrange is any faster than using range, you can simply do:

In [1]: %timeit for _ in range(1000): True
10000 loops, best of 3: 37.8 µs per loop

In [2]: %timeit for _ in xrange(1000): True
10000 loops, best of 3: 29.6 µs per loop

And you will get the timings for them.

The major advantage of %timeit are:

• that you don't have to import timeit.timeit from the standard library, and run the code multiple times to figure out which is the better approach.

• %timeit will automatically calculate number of runs required for your code based on a total of 2 seconds execution window.

• You can also make use of current console variables without passing the whole code snippet as in case of timeit.timeit to built the variable that is built in an another environment that timeit works.

std::chrono::time_point<std::chrono::system_clock> now = std::chrono::system_clock::now();

This is a great place for auto:

auto now = std::chrono::system_clock::now();

Since you want to traffic at millisecond precision, it would be good to go ahead and covert to it in the time_point:

auto now_ms = std::chrono::time_point_cast<std::chrono::milliseconds>(now);

now_ms is a time_point, based on system_clock, but with the precision of milliseconds instead of whatever precision your system_clock has.

auto epoch = now_ms.time_since_epoch();

epoch now has type std::chrono::milliseconds. And this next statement becomes essentially a no-op (simply makes a copy and does not make a conversion):

auto value = std::chrono::duration_cast<std::chrono::milliseconds>(epoch);

Here:

long duration = value.count();

In both your and my code, duration holds the number of milliseconds since the epoch of system_clock.

This:

std::chrono::duration<long> dur(duration);

Creates a duration represented with a long, and a precision of seconds. This effectively reinterpret_casts the milliseconds held in value to seconds. It is a logic error. The correct code would look like:

std::chrono::milliseconds dur(duration);

This line:

std::chrono::time_point<std::chrono::system_clock> dt(dur);

creates a time_point based on system_clock, with the capability of holding a precision to the system_clock's native precision (typically finer than milliseconds). However the run-time value will correctly reflect that an integral number of milliseconds are held (assuming my correction on the type of dur).

Even with the correction, this test will (nearly always) fail though:

if (dt != now)

Because dt holds an integral number of milliseconds, but now holds an integral number of ticks finer than a millisecond (e.g. microseconds or nanoseconds). Thus only on the rare chance that system_clock::now() returned an integral number of milliseconds would the test pass.

But you can instead:

if (dt != now_ms)

And you will now get your expected result reliably.

Putting it all together:

int main ()
{
    auto now = std::chrono::system_clock::now();
    auto now_ms = std::chrono::time_point_cast<std::chrono::milliseconds>(now);

    auto value = now_ms.time_since_epoch();
    long duration = value.count();

    std::chrono::milliseconds dur(duration);

    std::chrono::time_point<std::chrono::system_clock> dt(dur);

    if (dt != now_ms)
        std::cout << "Failure." << std::endl;
    else
        std::cout << "Success." << std::endl;
}

Personally I find all the std::chrono overly verbose and so I would code it as:

int main ()
{
    using namespace std::chrono;
    auto now = system_clock::now();
    auto now_ms = time_point_cast<milliseconds>(now);

    auto value = now_ms.time_since_epoch();
    long duration = value.count();

    milliseconds dur(duration);

    time_point<system_clock> dt(dur);

    if (dt != now_ms)
        std::cout << "Failure." << std::endl;
    else
        std::cout << "Success." << std::endl;
}

Which will reliably output:

Success.

Finally, I recommend eliminating temporaries to reduce the code converting between time_point and integral type to a minimum. These conversions are dangerous, and so the less code you write manipulating the bare integral type the better:

int main ()
{
    using namespace std::chrono;
    // Get current time with precision of milliseconds
    auto now = time_point_cast<milliseconds>(system_clock::now());
    // sys_milliseconds is type time_point<system_clock, milliseconds>
    using sys_milliseconds = decltype(now);
    // Convert time_point to signed integral type
    auto integral_duration = now.time_since_epoch().count();
    // Convert signed integral type to time_point
    sys_milliseconds dt{milliseconds{integral_duration}};
    // test
    if (dt != now)
        std::cout << "Failure." << std::endl;
    else
        std::cout << "Success." << std::endl;
}

The main danger above is not interpreting integral_duration as milliseconds on the way back to a time_point. One possible way to mitigate that risk is to write:

    sys_milliseconds dt{sys_milliseconds::duration{integral_duration}};

This reduces risk down to just making sure you use sys_milliseconds on the way out, and in the two places on the way back in.

And one more example: Let's say you want to convert to and from an integral which represents whatever duration system_clock supports (microseconds, 10^th of microseconds or nanoseconds). Then you don't have to worry about specifying milliseconds as above. The code simplifies to:

int main ()
{
    using namespace std::chrono;
    // Get current time with native precision
    auto now = system_clock::now();
    // Convert time_point to signed integral type
    auto integral_duration = now.time_since_epoch().count();
    // Convert signed integral type to time_point
    system_clock::time_point dt{system_clock::duration{integral_duration}};
    // test
    if (dt != now)
        std::cout << "Failure." << std::endl;
    else
        std::cout << "Success." << std::endl;
}

This works, but if you run half the conversion (out to integral) on one platform and the other half (in from integral) on another platform, you run the risk that system_clock::duration will have different precisions for the two conversions.

If you're in the middle of a commit (i.e. in your editor already), you can cancel it by deleting all lines above the first #. That will abort the commit.

So you can delete all lines so that the commit message is empty, then save the file:

You'll then get a message that says Aborting commit due to empty commit message..

EDIT:

You can also delete all the lines and the result will be exactly the same.

To delete all lines in vim (if that is your default editor), once you're in the editor, type gg to go to the first line, then dG to delete all lines. Finally, write and quit the file with wq and your commit will be aborted.

I believe, it is not possible to mock constructors using mockito. Instead, I suggest following approach

Class First {

   private Second second;

   public First(int num, String str) {
     if(second== null)
     {
       //when junit runs, you get the mocked object(not null), hence don't 
       //initialize            
       second = new Second(str);
     }
     this.num = num;
   }

   ... // some other methods
}

And, for test:

class TestFirst{
    @InjectMock
    First first;//inject mock the real testable class
    @Mock
    Second second

    testMethod(){

        //now you can play around with any method of the Second class using its 
        //mocked object(second),like:
        when(second.getSomething(String.class)).thenReturn(null);
    }
}

$('.modal').on('shown.bs.modal',function(){      //correct here use 'shown.bs.modal' event which comes in bootstrap3
  $(this).find('iframe').attr('src','http://www.google.com')
})

As shown above use 'shown.bs.modal' event which comes in bootstrap 3.

EDIT :-

and just try to open some other url from iframe other than google.com ,it will not allow you to open google.com due to some security threats.

The reason for this is, that Google is sending an "X-Frame-Options: SAMEORIGIN" response header. This option prevents the browser from displaying iFrames that are not hosted on the same domain as the parent page.

Try to write \ZIPARCHIVE instead of ZIPARCHIVE.

Asp.net is pretty good at automatically converting .net objects to json. Your List object if returned in your webmethod should return a json/javascript array. What I mean by this is that you shouldn't change the return type to string (because that's what you think the client is expecting) when returning data from a method. If you return a .net array from a webmethod a javaScript array will be returned to the client. It doesn't actually work too well for more complicated objects, but for simple array data its fine.

Of course, it's then up to you to do what you need to do on the client side.

I would be thinking something like this:

[WebMethod]
public static List GetProducts()
{
   var products  = context.GetProducts().ToList();   
   return products;
}

There shouldn't really be any need to initialise any custom converters unless your data is more complicated than simple row/col data

Just remove

[tabBarController presentModalViewController:viewController animated:YES];

and keep

[self dismissModalViewControllerAnimated:YES];

You can use the shell for this purpose.

Set shl = CreateObject("WScript.Shell") 
shl.Run "cmd mkdir YourDir" & copy "

It should be noted that the documentation recommends using a Layout rather than Canvas.drawText directly. My full answer about using a StaticLayout is here, but I will provide a summary below.

String text = "This is some text.";

TextPaint textPaint = new TextPaint();
textPaint.setAntiAlias(true);
textPaint.setTextSize(16 * getResources().getDisplayMetrics().density);
textPaint.setColor(0xFF000000);

int width = (int) textPaint.measureText(text);
StaticLayout staticLayout = new StaticLayout(text, textPaint, (int) width, Layout.Alignment.ALIGN_NORMAL, 1.0f, 0, false);
staticLayout.draw(canvas);

Here is a fuller example in the context of a custom view:

public class MyView extends View {

    String mText = "This is some text.";
    TextPaint mTextPaint;
    StaticLayout mStaticLayout;

    // use this constructor if creating MyView programmatically
    public MyView(Context context) {
        super(context);
        initLabelView();
    }

    // this constructor is used when created from xml
    public MyView(Context context, AttributeSet attrs) {
        super(context, attrs);
        initLabelView();
    }

    private void initLabelView() {
        mTextPaint = new TextPaint();
        mTextPaint.setAntiAlias(true);
        mTextPaint.setTextSize(16 * getResources().getDisplayMetrics().density);
        mTextPaint.setColor(0xFF000000);

        // default to a single line of text
        int width = (int) mTextPaint.measureText(mText);
        mStaticLayout = new StaticLayout(mText, mTextPaint, (int) width, Layout.Alignment.ALIGN_NORMAL, 1.0f, 0, false);

        // New API alternate
        //
        // StaticLayout.Builder builder = StaticLayout.Builder.obtain(mText, 0, mText.length(), mTextPaint, width)
        //        .setAlignment(Layout.Alignment.ALIGN_NORMAL)
        //        .setLineSpacing(1, 0) // multiplier, add
        //        .setIncludePad(false);
        // mStaticLayout = builder.build();
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        // Tell the parent layout how big this view would like to be
        // but still respect any requirements (measure specs) that are passed down.

        // determine the width
        int width;
        int widthMode = MeasureSpec.getMode(widthMeasureSpec);
        int widthRequirement = MeasureSpec.getSize(widthMeasureSpec);
        if (widthMode == MeasureSpec.EXACTLY) {
            width = widthRequirement;
        } else {
            width = mStaticLayout.getWidth() + getPaddingLeft() + getPaddingRight();
            if (widthMode == MeasureSpec.AT_MOST) {
                if (width > widthRequirement) {
                    width = widthRequirement;
                    // too long for a single line so relayout as multiline
                    mStaticLayout = new StaticLayout(mText, mTextPaint, width, Layout.Alignment.ALIGN_NORMAL, 1.0f, 0, false);
                }
            }
        }

        // determine the height
        int height;
        int heightMode = MeasureSpec.getMode(heightMeasureSpec);
        int heightRequirement = MeasureSpec.getSize(heightMeasureSpec);
        if (heightMode == MeasureSpec.EXACTLY) {
            height = heightRequirement;
        } else {
            height = mStaticLayout.getHeight() + getPaddingTop() + getPaddingBottom();
            if (heightMode == MeasureSpec.AT_MOST) {
                height = Math.min(height, heightRequirement);
            }
        }

        // Required call: set width and height
        setMeasuredDimension(width, height);
    }

    @Override
    protected void onDraw(Canvas canvas) {
        super.onDraw(canvas);
        // do as little as possible inside onDraw to improve performance

        // draw the text on the canvas after adjusting for padding
        canvas.save();
        canvas.translate(getPaddingLeft(), getPaddingTop());
        mStaticLayout.draw(canvas);
        canvas.restore();
    }
}

Yep, using the staticmethod decorator

class MyClass(object):
    @staticmethod
    def the_static_method(x):
        print(x)

MyClass.the_static_method(2)  # outputs 2

Note that some code might use the old method of defining a static method, using staticmethod as a function rather than a decorator. This should only be used if you have to support ancient versions of Python (2.2 and 2.3)

class MyClass(object):
    def the_static_method(x):
        print(x)
    the_static_method = staticmethod(the_static_method)

MyClass.the_static_method(2)  # outputs 2

This is entirely identical to the first example (using @staticmethod), just not using the nice decorator syntax

Finally, use staticmethod sparingly! There are very few situations where static-methods are necessary in Python, and I've seen them used many times where a separate "top-level" function would have been clearer.

The following is verbatim from the documentation::

A static method does not receive an implicit first argument. To declare a static method, use this idiom:

class C:
    @staticmethod
    def f(arg1, arg2, ...): ...

The @staticmethod form is a function decorator – see the description of function definitions in Function definitions for details.

It can be called either on the class (such as C.f()) or on an instance (such as C().f()). The instance is ignored except for its class.

Static methods in Python are similar to those found in Java or C++. For a more advanced concept, see classmethod().

For more information on static methods, consult the documentation on the standard type hierarchy in The standard type hierarchy.

New in version 2.2.

Changed in version 2.4: Function decorator syntax added.

It's part of the exception handling. The gcc EH mechanism allows to mix various EH models, and a personality routine is invoked to determine if an exception match, what finalization to invoke, etc. This specific personality routine is for C++ exception handling (as opposed to, say, gcj/Java exception handling).

SELECT CAST(FLOOR(CAST(GETDATE() AS float)) as datetime)

or

SELECT CONVERT(datetime,FLOOR(CONVERT(float,GETDATE())))

To add on to what Noel M stated, you can look at this question, and this answer shows that the constant is reused.

http://forums.java.net/jive/message.jspa?messageID=17122

String constant are always "interned" so there is not really a need for such constant.

String s=""; String t=""; boolean b=s==t; // true

You can also use START WITH to start a sequence from a particular point, although setval accomplishes the same thing, as in Euler's answer, eg,

SELECT MAX(a) + 1 FROM foo;
CREATE SEQUENCE foo_a_seq START WITH 12345; -- replace 12345 with max above
ALTER TABLE foo ALTER COLUMN a SET DEFAULT nextval('foo_a_seq');

I know that maybe my answer is too specific for a embedded QNAP server, but I ended here trying to install Yii:

For me, inside a QNAP NAS through PuTTY, after trying all tricks above, and updating PATH to no avail, the only cmd line that works is:

 /mnt/ext/opt/apache/bin/php /usr/local/bin/composer create-project yiisoft/yii2-app-basic basic

Of course, adapt your path accordingly...

If I do a which composer, I have a correct answer, but if I do a which php nothing returns.

Besides that, trying to run

/mnt/ext/opt/apache/bin/php composer create-project yiisoft/yii2-app-basic basic

or referring to

composer.phar

didn't worked too...

For :

• OS X : 10.11.6

• Java : 8

I confirm the answer of @Morrie .

   export JAVA_HOME=/Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin/Contents/Home;

But if you are running containers your life will be easier

What about this for a catch all...

if (string.IsNullOrEmpty(x.Trim())
{
}

This will trim all the spaces if they are there avoiding the performance penalty of IsWhiteSpace, which will enable the string to meet the "empty" condition if its not null.

I also think this is clearer and its generally good practise to trim strings anyway especially if you are putting them into a database or something.

Why not get the square root of the number? If its negative - java will throw an error and we will handle it.

         try {
            d = Math.sqrt(THE_NUMBER);
         }
         catch ( ArithmeticException e ) {
            console.putln("Number is negative.");
         }

To understand both the methods let's take an example:

int i =0;
MessageBox.Show(i.ToString());
MessageBox.Show(Convert.ToString(i)); 

Here both the methods are used to convert the string but the basic difference between them is: Convert function handles NULL, while i.ToString() does not it will throw a NULL reference exception error. So as good coding practice using convert is always safe.

Let's see another example:

string s;
object o = null;
s = o.ToString(); 
//returns a null reference exception for s. 

string s;
object o = null;
s = Convert.ToString(o); 
//returns an empty string for s and does not throw an exception.

You can iterate through JavaScript objects this way:

for(var attributename in myobject){
    console.log(attributename+": "+myobject[attributename]);
}

myobject could be your json.data

For Python 3:

ListOfStrings = []
ListOfStrings.append('foo')
ListOfStrings.append('oof')
for idx, item in enumerate(ListOfStrings):
if 'foo' in item:
    ListOfStrings[idx] = "bar"

The suggested answer only works for certain versions of ruby. Some commenters suggest using ruby-dev; that didn't work for me either.

sudo apt-get install ruby-all-dev

worked for me.

I had the same question and more, and though this thread is old, it is still a good one, so in summary for SSRS 2008R2 I found...

Situations

1. You want to use a value from a URL to look up data
2. You want to display a parameter from a URL in a report
3. You want to pass a parameter from one report to another report

Actions

If applicable, be sure to replace Reports/Pages/Report.aspx?ItemPath= with ReportServer?. In other words: Instead of this:

http://server/Reports/Pages/Report.aspx?ItemPath=/ReportFolder/ReportSubfolder/ReportName

Use this syntax:

http://server/ReportServer?/ReportFolder/ReportSubfolder/ReportName

Add parameter(s) to the report and set as hidden (or visible if user action allowed, though keep in mind that while the report parameter will change, the URL will not change based on an updated entry).

Attach parameters to URL with &ParameterName=Value

Parameters can be referenced or displayed in report using @ParameterName, whether they're set in the report or in the URL

To hide the toolbar where parameters are displayed, add &rc:Toolbar=false to the URL (reference)

Putting that all together, you can run a URL with embedded values, or call this as an action from one report and read by another report:

http://server.domain.com/ReportServer?/ReportFolder1/ReportSubfolder1/ReportName&UserID=ABC123&rc:Toolbar=false

In report dataset properties query: SELECT stuff FROM view WHERE User = @UserID

In report, set expression value to [UserID] (or =Fields!UserID.Value)

Keep in mind that if a report has multiple parameters, you might need to include all parameters in the URL, even if blank, depending on how your dataset query is written.

To pass a parameter using Action = Go to URL, set expression to:

="http://server.domain.com/ReportServer?/ReportFolder1/ReportSubfolder1/ReportName&UserID="
 &Fields!UserID.Value 
 &"&rc:Toolbar=false"
 &"&rs:ClearSession=True"

Be sure to have a space after an expression if followed by & (a line break is isn't enough). No space is required before an expression. This method can pass a parameter but does not hide it as it is visible in the URL.

If you don't include &rs:ClearSession=True then the report won't refresh until browser session cache is cleared.

To pass a parameter using Action = Go to report:

• Specify the report
• Add parameter(s) to run the report
• Add parameter(s) you wish to pass (the parameters need to be defined in the destination report, so to my knowledge you can't use URL-specific commands such as rc:toolbar using this method); however, I suppose it would be possible to read or set the Prompt User checkbox, as seen in reporting sever parameters, through custom code in the report.)

For reference, / = %2f

If you want to remove/clean all the values from local storage than use

localStorage.clear();

And if you want to remove the specific item from local storage than use the following code

localStorage.removeItem(key);

'<>' is from the SQL-92 standard and '!=' is a proprietary T-SQL operator. It's available in other databases as well, but since it isn't standard you have to take it on a case-by-case basis.

In most cases, you'll know what database you're connecting to so this isn't really an issue. At worst you might have to do a search and replace in your SQL.

This depends not only on the operating system in question, but also on configuration, potentially real-time configuration.

For Linux:

cat /proc/sys/fs/file-max

will show the current maximum number of file descriptors total allowed to be opened simultaneously. Check out http://www.cs.uwaterloo.ca/~brecht/servers/openfiles.html

There is a great library for that, called TwoWayView, it's very easy to implement, just include the project library into your work space and add it as a library project to your original project, and then follow the following steps which are originally mentioned here:

First, let's add a style indicating the orientation of the ListView (horizontal or vertical) in (res/values/styles.xml):

<style name="TwoWayView">
    <item name="android:orientation">horizontal</item>
</style>

Then,

In your Layout XML, use the following code to add the TwoWayView:

<org.lucasr.twowayview.TwoWayView 
     xmlns:android="http://schemas.android.com/apk/res/android"
     xmlns:tools="http://schemas.android.com/tools"
     xmlns:app="http://schemas.android.com/apk/res-auto"
     android:id="@+id/lvItems"
     style="@style/TwoWayView"
     android:layout_width="match_parent"
     android:layout_height="match_parent"
     android:drawSelectorOnTop="false"
     tools:context=".MainActivity" />

and finally, just declare it and deal with it like any regular ListView:

TwoWayView lvTest = (TwoWayView) findViewById(R.id.lvItems);

All the methods of ListView will work here as usual, but there is only one difference I noticed, which is when setting the choice mode, the method setChoiceMode not takes an int value but a value from enum called ChoiceMode, so list_view.setChoiceMode(ListView.CHOICE_MODE_SINGLE); will be lvTest.setChoiceMode(ChoiceMode.SINGLE); // or MULTIPLE or NONE.

Contributing to ferrix example,

class Battery():

    def __init__(self, battery_size = 60):
        self.battery_size = battery_size
    def get_range(self):
        if self.battery_size == 70:
            range = 240
        elif self.battery_size == 85:
        range = 270

        message = "This car can go approx " + str(range)
        message += "Fully charge"
        print(message)

My message will not execute, because none of my conditions are fulfill therefore receiving " UnboundLocalError: local variable 'range' referenced before assignment"

def get_range(self):
    if self.battery_size <= 70:
        range = 240
    elif self.battery_size >= 85:
        range = 270

As you are trying to add a string of CSS to <head> with JavaScript? injecting a string of CSS into a page it is easier to do this with the <link> element than the <style> element.

The following adds p { color: green; } rule to the page.

<link rel="stylesheet" type="text/css" href="data:text/css;charset=UTF-8,p%20%7B%20color%3A%20green%3B%20%7D" />

You can create this in JavaScript simply by URL encoding your string of CSS and adding it the HREF attribute. Much simpler than all the quirks of <style> elements or directly accessing stylesheets.

var linkElement = this.document.createElement('link');
linkElement.setAttribute('rel', 'stylesheet');
linkElement.setAttribute('type', 'text/css');
linkElement.setAttribute('href', 'data:text/css;charset=UTF-8,' + encodeURIComponent(myStringOfstyles));

This will work in IE 5.5 upwards

The solution you have marked will work but this solution requires fewer dom operations and only a single element.

Try the onbeforeunload event: It is fired just before the page is unloaded. It also allows you to ask back if the user really wants to leave. See the demo onbeforeunload Demo.

Alternatively, you can send out an Ajax request when he leaves.

One of the Related posts gave me the (simple) answer.

Apparently the auto value on the grid-template-rows property does exactly what I was looking for.

.grid {
    display:grid;
    grid-template-columns: 1fr 1.5fr 1fr;
    grid-template-rows: auto auto 1fr 1fr 1fr auto auto;
    grid-gap:10px;
    height: calc(100vh - 10px);
}

Instead of using jQuery, use css property text-overflow:ellipsis. It will automatically truncate the string.

.truncated { display:inline-block; 
             max-width:100px; 
             overflow:hidden; 
             text-overflow:ellipsis; 
             white-space:nowrap; 
           }

Here is another one:

This one is also based on the latest Chrome engine but it's much easier to use than CEF. It's a single .NET dll that you can simply reference and use.

step 1 : make a web service on your server

step 2 : make your application make a call to the web service and receive result sets

I had the same problem but I solved it differently. I don't know if it's a good way of doing it, but it works great for what I need.

I used @Inject on the constructor of the child component, like this:

import { Component, OnInit, Inject } from '@angular/core';
import { ParentComponent } from '../views/parent/parent.component';

export class ChildComponent{
    constructor(@Inject(ParentComponent) private parent: ParentComponent){

    }

    someMethod(){
        this.parent.aPublicProperty = 2;
    }
}

This worked for me, you only need to declare the method or property you want to call as public.

In my case, the AppComponent handles the routing, and I'm using badges in the menu items to alert the user that new unread messages are available. So everytime a user reads a message, I want that counter to refresh, so I call the refresh method so that the number at the menu nav gets updated with the new value. This is probably not the best way but I like it for its simplicity.

I was getting this error:

The type com.ibm.portal.state.exceptions.StateException cannot be resolved. It is indirectly referenced from required .class files

Doing the following fixed it for me:

Properties -> Java build path -> Libraries -> Server Library[wps.base.v61]unbound -> Websphere Portal v6.1 on WAS 7 -> Finish -> OK

Because a reference is 'managed', but not hydrated, it can also allow you to remove an entity by ID, without needing to load it into memory first.

As you can't remove an unmanaged entity, it's just plain silly to load all fields using find(...) or createQuery(...), only to immediately delete it.

MyLargeObject myObject = em.getReference(MyLargeObject.class, objectId);
em.remove(myObject);

Add multiDexEnabled true in your defaultConfig in the app level gradle.

defaultConfig {
    applicationId "your application id"
    minSdkVersion 16
    targetSdkVersion 25
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner"android.support.test.runner.AndroidJUnitRunner"
    multiDexEnabled true
}

Create the Intent like this:

   Uri uriSms = Uri.parse("smsto:1234567899");   
   Intent intentSMS = new Intent(Intent.ACTION_SENDTO, uriSms);   
   intentSMS.putExtra("sms_body", "The SMS text");   
   startActivity(intentSMS); 

If you're using the South package to handle database migrations (highly recommended), then you could just use the ./manage.py migrate appname zero command.

Otherwise, I'd recommend the ./manage.py dbshell command, piping in SQL commands on standard input.

var newTH = document.createElement('th');
newTH.setAttribute("onclick", "removeColumn(#)");
newTH.setAttribute("id", "#");

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

class A:
  def __init__(self, function):
    self.function = function
  def kill(self):
    self.function(self)

def delete(object):                        #We are no longer in A object
  del object

a = A(delete)
print(a)
a.kill()
print(a)

May this code work ?

To throw out another option, why not set the working directory (preferably via a script) to the desktop using setwd('C:\John\Desktop') and then read the files just using file names

Use the form Initialize event, e.g.:

Private Sub UserForm_Initialize()
    TextBox1.Value = Format(Date, "mm/dd/yyyy")
End Sub

Guzzle implements PSR-7. That means that it will by default store the body of a message in a Stream that uses PHP temp streams. To retrieve all the data, you can use casting operator:

$contents = (string) $response->getBody();

You can also do it with

$contents = $response->getBody()->getContents();

The difference between the two approaches is that getContents returns the remaining contents, so that a second call returns nothing unless you seek the position of the stream with rewind or seek .

$stream = $response->getBody();
$contents = $stream->getContents(); // returns all the contents
$contents = $stream->getContents(); // empty string
$stream->rewind(); // Seek to the beginning
$contents = $stream->getContents(); // returns all the contents

Instead, usings PHP's string casting operations, it will reads all the data from the stream from the beginning until the end is reached.

$contents = (string) $response->getBody(); // returns all the contents
$contents = (string) $response->getBody(); // returns all the contents

Others already posted. but I give a simple example here so that can help some new comers.

Step-1: In your index.html file reference jquery cdn

     <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.0/jquery.min.js"></script>

Step-2: assume we want to show div or hide div on click of a button:

 <input type="button" value="Add New" (click)="ShowForm();">


 <div class="container">
  //-----.HideMe{display:none;} is a css class----//

  <div id="PriceForm" class="HideMe">
     <app-pricedetails></app-pricedetails>
  </div>
  <app-pricemng></app-pricemng>
 </div>

Step-3:In the component file bellow the import declare $ as bellow:

declare var $: any;

than create function like bellow:

 ShowForm(){
   $('#PriceForm').removeClass('HideMe');
 }

It will work with latest Angular and JQuery

Here is what you can do if you want to add a column of numbers in Excel. ( I am using Excel 2010 but should not make a difference.)

Example: Lets say you want to add the cells in Column B form B10 to B100 & want the answer to be in cell X or be Variable X ( X can be any cell or any variable you create such as Dim X as integer, etc). Here is the code:

Range("B5") = "=SUM(B10:B100)"

or

X = "=SUM(B10:B100)

There are no quotation marks inside the parentheses in "=Sum(B10:B100) but there are quotation marks inside the parentheses in Range("B5"). Also there is a space between the equals sign and the quotation to the right of it.

It will not matter if some cells are empty, it will simply see them as containing zeros!

This should do it for you!

@echo off
for %%f in (*.txt) do (
    ren "%%~nf%%~xf" "%%~nf 1.1%%~xf"
)

There are several situations that will give you this particular error. In the case of the OP there was a value defined explicitly as a string. So I have to assume that maybe this came from a dropdown, or web service or raw JSON string.

In that case a simple cast <Fruit> fruitString or fruitString as Fruit is the only solution (see other answers). You wouldn't ever be able to improve on this at compile time. [Edit: See my other answer about <const>] !

However it's very easy to run into this same error when using constants in your code that aren't ever intended to be of type string. My answer focuses on that second scenario:

First of all: Why are 'magic' string constants often better than an enum?

• I like the way a string constant looks vs. an enum - it's compact and 'javascripty'
• Makes more sense if the component you're using already uses string constants.
• Having to import an 'enum type' just to get an enumeration value can be troublesome in itself
• Whatever I do I want it to be compile safe so if I add remove a valid value from the union type, or mistype it then it MUST give a compile error.

Fortunately when you define:

export type FieldErrorType = 'none' | 'missing' | 'invalid'

...you're actually defining a union of types where 'missing' is actually a type!

I often run into the 'not assignable' error if I have a string like 'banana' in my typescript and the compiler thinks I meant it as a string, whereas I really wanted it to be of type banana. How smart the compiler is able to be will depend on the structure of your code.

Here's an example of when I got this error today:

// this gives me the error 'string is not assignable to type FieldErrorType'
fieldErrors: [ { fieldName: 'number', error: 'invalid' } ]

As soon as I found out that 'invalid' or 'banana' could be either a type or a string I realized I could just assert a string into that type. Essentially cast it to itself, and tell the compiler no I don't want this to be a string!

// so this gives no error, and I don't need to import the union type too
fieldErrors: [ { fieldName: 'number', error: <'invalid'> 'invalid' } ]

So what's wrong with just 'casting' to FieldErrorType (or Fruit)

// why not do this?
fieldErrors: [ { fieldName: 'number', error: <FieldErrorType> 'invalid' } ]

It's not compile time safe:

 <FieldErrorType> 'invalidddd';  // COMPILER ALLOWS THIS - NOT GOOD!
 <FieldErrorType> 'dog';         // COMPILER ALLOWS THIS - NOT GOOD!
 'dog' as FieldErrorType;        // COMPILER ALLOWS THIS - NOT GOOD!

Why? This is typescript so <FieldErrorType> is an assertion and you are telling the compiler a dog is a FieldErrorType! And the compiler will allow it!

BUT if you do the following, then the compiler will convert the string to a type

 <'invalid'> 'invalid';     // THIS IS OK  - GOOD
 <'banana'> 'banana';       // THIS IS OK  - GOOD
 <'invalid'> 'invalidddd';  // ERROR       - GOOD
 <'dog'> 'dog';             // ERROR       - GOOD

Just watch out for stupid typos like this:

 <'banana'> 'banan';    // PROBABLY WILL BECOME RUNTIME ERROR - YOUR OWN FAULT!

Another way to solve the problem is by casting the parent object:

My definitions were as follows:

export type FieldName = 'number' | 'expirationDate' | 'cvv'; export type FieldError = 'none' | 'missing' | 'invalid'; export type FieldErrorType = { field: FieldName, error: FieldError };

Let's say we get an error with this (the string not assignable error):

  fieldErrors: [ { field: 'number', error: 'invalid' } ]

We can 'assert' the whole object as a FieldErrorType like this:

  fieldErrors: [ <FieldErrorType> { field: 'number', error: 'invalid' } ]

Then we avoid having to do <'invalid'> 'invalid'.

But what about typos? Doesn't <FieldErrorType> just assert whatever is on the right to be of that type. Not in this case - fortunately the compiler WILL complain if you do this, because it's clever enough to know it's impossible:

  fieldErrors: [ <FieldErrorType> { field: 'number', error: 'dog' } ]

Inspired by anubhava's answer, which I think is not actually acceptable as it runs each command twice.

save_output() { 
   exec 1>&3 
   { [ -f /tmp/current ] && mv /tmp/current /tmp/last; }
   exec > >(tee /tmp/current)
}

exec 3>&1
trap save_output DEBUG

This way the output of last command is in /tmp/last and the command is not called twice.

i used the following method & it worked fine for me

$('#mybutton').click(function(){
        clearForm($('#mybutton').closest("form"));
    });

$('#mybutton').closest("form") did the trick for me.

From the wampserver 3.x onwards, changing the listening port number of Apache does not require any particular Apache skills (http.conf, virtualhost,...), you just have to click button - assuming you're running Windows OS! :

1. In the tray, right click green/running WAMP icon
2. Select menu Tools
3. In the section Port used by Apache: xx, click Use a port other than 80 (i.e. default port configuration)
4. Enter the desired port number in the popup window - usually 8080 as alternative Web port

NB: For alternative port: check official IANA Service Name and Transport Protocol Port Number Registry

SSLSHopper has some pretty thorough articles about moving between different servers.

http://www.sslshopper.com/how-to-move-or-copy-an-ssl-certificate-from-one-server-to-another.html

Just pick the relevant link at bottom of this page.

Note: they have an online converter which gives them access to your private key. They can probably be trusted but it would be better to use the OPENSSL command (also shown on this site) to keep the private key private on your own machine.

Maybe you can write a function as follows:

var addParams = function(key, val, url) {
  var arr = url.split('?');
  if(arr.length == 1) {
    return url + '?' + key + '=' + val;
  }
  else if(arr.length == 2) {
    var params = arr[1].split('&');
    var p = {};
    var a = [];
    var strarr = [];
    $.each(params, function(index, element) {
      a = element.split('=');
      p[a[0]] = a[1];
      })
    p[key] = val;
    for(var o in p) {
      strarr.push(o + '=' + p[o]);
    }
    var str = strarr.join('&');
    return(arr[0] + '?' + str);
  }
}

You can delete all the rows with this command.But remember one thing that once you run truncate command you cannot rollback it.

  truncate tableName;

From what I searched, at this moment there is no option from Google in the Maps API v3 and there is an issue on the Google Maps API going back to 2008. There are some older questions - Add "Search Area" outline onto google maps result , Google has started highlighting search areas in Pink color. Is this feature available in Google Maps API 3? and you might find some newer answers here with updated information, but this is not a feature.

What you can do is draw shapes on your map - but for this you need to have the coordinates of the borders of your region.

Now, in order to get the administrative area boundaries, you will have to do a little work: http://www.gadm.org/country (if you are lucky and there is enough level of detail available there).

On this website you can locally download a file (there are many formats available) with the .kmz extension. Unzip it and you will have a .kml file which contains most administrative areas (cities, villages).

From this point on, when the user searches for a city/village, you simply retrieve the boundaries and draw around those coordinates on the map - https://developers.google.com/maps/documentation/javascript/overlays#Polygons

I hope this helps you! Good luck!

UPDATE: I made the borders of this city using the coordinates above

                   var ctaLayer = new google.maps.KmlLayer({
                       url: 'https://www.dropbox.com/s/0grhlim3q4572jp/ROU_adm2%20-%20Copy.kml?dl=1'
  });
  ctaLayer.setMap(map);

(I put a small kml file on my Dropbox containing the borders of a single city)

Note that this uses the Google built in KML system, in which it their server gets the file, computes the view and spits it back to you - it has limited usage and I used it to show you how the borders look. In your application you should be able to parse the coordinates from the kml file, put them in an array (as the polygon documentation tells you - https://developers.google.com/maps/documentation/javascript/examples/polygon-arrays ) and display them.

Note that there will be differences between the borders that Google sets on http://www.google.com/maps and the borders that you will get with this data.

Good luck!

UPDATE: http://pastebin.com/x2V1aarJ , http://pastebin.com/Gh55EDW5 These are the javascript files (they were minified, so I used an online tool to make them readable) from the website. If you are not fully satisfied with this my solution, feel free to study them.

Best of luck!

Try this:

window.open(url, '_blank');

This will open in new tab (if your code is synchronous and in this case it is. in other case it would open a window)

There are many solutions, here's a few I've come up with:

int main(int nArgs, char ** vArgs)
{
    vector<int> *v = new vector<int>(10);
    v->at(2); //Retrieve using pointer to member
    v->operator[](2); //Retrieve using pointer to operator member
    v->size(); //Retrieve size
    vector<int> &vr = *v; //Create a reference
    vr[2]; //Normal access through reference
    delete &vr; //Delete the reference. You could do the same with
                //a pointer (but not both!)
}

This has been here quite a while but posting this. Might be useful for someone.

@RequestMapping( "/{id}/**" )
public void foo( @PathVariable String id, HttpServletRequest request ) {
    String urlTail = new AntPathMatcher()
            .extractPathWithinPattern( "/{id}/**", request.getRequestURI() );
}

It appears that your package manager failed to create the database named $user for you. The reason that

psql -d template1

works for you is that template1 is a database created by postgres itself, and is present on all installations. You are apparently able to log in to template1, so you must have some rights assigned to you by the database. Try this at a shell prompt:

createdb

and then see if you can log in again with

psql -h localhost

This will simply create a database for your login user, which I think is what you are looking for. If createdb fails, then you don't have enough rights to make your own database, and you will have to figure out how to fix the homebrew package.

Evaluating "1,2,3" results in (1, 2, 3), a tuple. As you've discovered, tuples are immutable. Convert to a list before processing.

This error is because your server doesn't have a valid SSL certificate. Hence we need to tell the client to use a different TrustManager. Here is a sample code:

SSLContext ctx = SSLContext.getInstance("TLS");
X509TrustManager tm = new X509TrustManager() {

    public void checkClientTrusted(X509Certificate[] xcs, String string) throws CertificateException {
    }

    public void checkServerTrusted(X509Certificate[] xcs, String string) throws CertificateException {
    }

    public X509Certificate[] getAcceptedIssuers() {
        return null;
    }
};
ctx.init(null, new TrustManager[]{tm}, null);
SSLSocketFactory ssf = new SSLSocketFactory(ctx,SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
ClientConnectionManager ccm = base.getConnectionManager();
SchemeRegistry sr = ccm.getSchemeRegistry();
sr.register(new Scheme("https", 443, ssf));

client = new DefaultHttpClient(ccm, base.getParams());

I have been working on to write a custom module in Drupal 7 and got the same error:

Notice: Trying to get property of non-object

My code is something like this:

function example_node_access($node, $op, $account) {
  if ($node->type == 'page' && $op == 'update') {
    drupal_set_message('This poll has been published, you may not make changes to it.','error');
    return NODE_ACCESS_DENY;    
  }
}

Solution: I just added a condition if (is_object($sqlResult)), and everything went fine.

Here is my final code:

function mediaten_node_access($node, $op, $account) {

    if (is_object($node)){

     if ($node->type == 'page' && $op == 'update') {
       drupal_set_message('This poll has been published, you may not make changes.','error');
       return NODE_ACCESS_DENY;    
      }

    }

}

You could also just use the NSUUID API:

let uuid = NSUUID()

If you want to get the string value back out, you can use uuid.UUIDString.

Note that NSUUID is available from iOS 6 and up.

You could use regex as this will give you the string if it matches the requirements. The code would be something like:

const address = "1345 albany street, Bellevue WA 42344";
const regex = /[1-9][0-9]* [a-zA-Z]+ [a-zA-Z]+/;
const matchedResult = address.match(regex);

console.log(matchedResult[0]); // This will give you 1345 albany street.

So to break the code down. [1-9][0-9]* basically means the first number cannot be a zero and has to be a number between 1-9 and the next number can be any number from 0-9 and can occur zero or more times as sometimes the number is just one digit and then it matches a space. [a-zA-Z] basically matches all capital letters to small letters and has to occur one or more times and this is repeated.

To install pip on a mac (osx), the following one liner worked great for me:

sudo easy_install pip

If you want Monday as the start of your week, do this:

$date = '2015-10-12';
$day = date('N', strtotime($date));
$week_start = date('Y-m-d', strtotime('-'.($day-1).' days', strtotime($date)));
$week_end = date('Y-m-d', strtotime('+'.(7-$day).' days', strtotime($date)));

If you're using gcc and want to disable the warning for selected code, you can use the #pragma compiler directive:

#pragma GCC diagnostic push
#pragma GCC diagnostic ignored "-Wunused-variable"
( your problematic library includes )
#pragma GCC diagnostic pop

For code you control, you may also use __attribute__((unused)) to instruct the compiler that specific variables are not used.

I've built a tool that does exactly that - qnm

qnm - A simple CLI utility for querying the node_modules directory.

Install it using:

npm i --global qnm

and run:

qnm [module]

for example:

> qnm lodash

lodash
+-- 4.17.5
+-- cli-table2
¦ +-- 3.10.1
+-- karma
  +-- 3.10.1

Which means we have lodash installed in the root of the node_modules and two other copies in the node_modules of cli-table2 and karma.

It's really fast, and has some nice features like tab completion and match search.

Just a little addition if one wants to parse a space separated text file line by line.

read_file = function (path)
local file = io.open(path, "rb") 
if not file then return nil end

local lines = {}

for line in io.lines(path) do
    local words = {}
    for word in line:gmatch("%w+") do 
        table.insert(words, word) 
    end    
  table.insert(lines, words)
end

file:close()
return lines;
end

You can use the == comparison operator to check if the variable is equal to the text:

if( $a == 'some text') {
    ...

You can also use strpos function to return the first occurrence of a string:

<?php
$mystring = 'abc';
$findme   = 'a';
$pos = strpos($mystring, $findme);

// Note our use of ===.  Simply == would not work as expected
// because the position of 'a' was the 0th (first) character.
if ($pos === false) {
    echo "The string '$findme' was not found in the string '$mystring'";
} else {
    echo "The string '$findme' was found in the string '$mystring'";
    echo " and exists at position $pos";
}

See documentation

result = db.engine.execute(text("<sql here>"))

executes the <sql here> but doesn't commit it unless you're on autocommit mode. So, inserts and updates wouldn't reflect in the database.

To commit after the changes, do

result = db.engine.execute(text("<sql here>").execution_options(autocommit=True))

If you want to produce output grouped by section, displaying only the top n records from each section something like this:

SECTION     SUBSECTION

deer        American Elk/Wapiti
deer        Chinese Water Deer
dog         Cocker Spaniel
dog         German Shephard
horse       Appaloosa
horse       Morgan

...then the following should work pretty generically with all SQL databases. If you want the top 10, just change the 2 to a 10 toward the end of the query.

select
    x1.section
    , x1.subsection
from example x1
where
    (
    select count(*)
    from example x2
    where x2.section = x1.section
    and x2.subsection <= x1.subsection
    ) <= 2
order by section, subsection;

To set up:

create table example ( id int, section varchar(25), subsection varchar(25) );

insert into example select 0, 'dog', 'Labrador Retriever';
insert into example select 1, 'deer', 'Whitetail';
insert into example select 2, 'horse', 'Morgan';
insert into example select 3, 'horse', 'Tarpan';
insert into example select 4, 'deer', 'Row';
insert into example select 5, 'horse', 'Appaloosa';
insert into example select 6, 'dog', 'German Shephard';
insert into example select 7, 'horse', 'Thoroughbred';
insert into example select 8, 'dog', 'Mutt';
insert into example select 9, 'horse', 'Welara Pony';
insert into example select 10, 'dog', 'Cocker Spaniel';
insert into example select 11, 'deer', 'American Elk/Wapiti';
insert into example select 12, 'horse', 'Shetland Pony';
insert into example select 13, 'deer', 'Chinese Water Deer';
insert into example select 14, 'deer', 'Fallow';

bind tells the running process to claim a port. i.e, it should bind itself to port 80 and listen for incomming requests. with bind, your process becomes a server. when you use connect, you tell your process to connect to a port that is ALREADY in use. your process becomes a client. the difference is important: bind wants a port that is not in use (so that it can claim it and become a server), and connect wants a port that is already in use (so it can connect to it and talk to the server)

From memset():

memset(myarray, 0, sizeof(myarray));

You can use sizeof(myarray) if the size of myarray is known at compile-time. Otherwise, if you are using a dynamically-sized array, such as obtained via malloc or new, you will need to keep track of the length.

Have you tested the speed?

i.e. Have you created a sample set of data and profiled it? It may not be as bad as you think.

This might also be something you could spawn off into a separate thread and give the illusion of speed!

Essentially console.log("Put a message here.") if the browser has a supporting console.

Another typical debugging method is using alerts, alert("Put a message here.")

RE: Update II

This seems to make sense, you are trying to automate QUnit tests, from what I have read on QUnit this is an in-browser unit testing suite/library. QUnit expects to run in a browser and therefore expects the browser to recognize all of the JavaScript functions you are calling.

Based on your Maven configuration it appears you are using Rhino to execute your Javascript at the command line/terminal. This is not going to work for testing browser specifics, you would likely need to look into Selenium for this. If you do not care about testing your JavaScript in a browser but are only testing JavaScript at a command line level (for reason I would not be familiar with) it appears that Rhino recognizes a print() method for evaluating expressions and printing them out. Checkout this documentation.

These links might be of interest to you.

You had thead in your selector, but there is no thead in your table. Also you had your selectors backwards. As you mentioned above, you wanted to be adding the tr class to the th, not vice-versa (although your comment seems to contradict what you wrote up above).

$('tr th').each(function(index){     if($('tr td').eq(index).attr('class') != ''){         // get the class of the td         var tdClass = $('tr td').eq(index).attr('class');         // add it to this th         $(this).addClass(tdClass );     } });

jQuery UI draggable and droppable are the two plugins I would use to achieve this effect. As for the insertion marker, I would investigate modifying the div (or container) element that was about to have content dropped into it. It should be possible to modify the border in some way or add a JavaScript/jQuery listener that listens for the hover (element about to be dropped) event and modifies the border or adds an image of the insertion marker in the right place.

Here is what I learned: PYTHONPATH is a directory to add to the Python import search path "sys.path", which is made up of current dir. CWD, PYTHONPATH, standard and shared library, and customer library. For example:

'/usr/lib/python3.6', '/usr/lib/python3.6/lib-dynload',

where the first path '' denotes the current dir., the 2nd path is via

%export PYTHONPATH=/home/username/Documents/DjangoTutorial/mySite 

which can be added to ~/.bashrc to make it permanent, and the rest are Python standard and dynamic shared library plus third-party library such as django.

As said not to mess with PYTHONHOME, even setting it to '' or 'None' will cause python3 shell to stop working:

% export PYTHONHOME=''
% python3
Fatal Python error: Py_Initialize: Unable to get the locale encoding
ModuleNotFoundError: No module named 'encodings'

Current thread 0x00007f18a44ff740 (most recent call first):

Note that if you start a Python script, the CWD will be the script's directory. For example:

username@bud:~/Documents/DjangoTutorial% python3 mySite/manage.py runserver
==== Printing sys.path ====
/home/username/Documents/DjangoTutorial/mySite # CWD is where manage.py resides
/usr/lib/python3.6
/usr/lib/python3.6/lib-dynload
/usr/local/lib/python3.6/dist-packages
/usr/lib/python3/dist-packages

You can also append a path to sys.path at run-time: Suppose you have a file Fibonacci.py in ~/Documents/Python directory:

username@bud:~/Documents/DjangoTutorial% python3 
>>> sys.path.append("/home/username/Documents")
>>> print(sys.path)
['', '/usr/lib/python3.6', '/usr/lib/python3.6/lib-dynload', 
'/usr/local/lib/python3.6/dist-packages', '/usr/lib/python3/dist-packages', 
'/home/username/Documents']
>>> from Python import Fibonacci as fibo

or via

% PYTHONPATH=/home/username/Documents:$PYTHONPATH
% python3
>>> print(sys.path)
['', 
'/home/username/Documents', '/home/username/Documents/DjangoTutorial/mySite', 
'/usr/lib/python3.6', '/usr/lib/python3.6/lib-dynload', 
'/usr/local/lib/python3.6/dist-packages', '/usr/lib/python3/dist-packages']
>>> from Python import Fibonacci as fibo

Here is how to bulk-create entities from column-separated file, leaving aside all unquoting and un-escaping routines:

SomeModel(Model):
    @classmethod
    def from_file(model, file_obj, headers, delimiter):
        model.objects.bulk_create([
            model(**dict(zip(headers, line.split(delimiter))))
            for line in file_obj],
            batch_size=None)

why not single line of code??

_yourScrollView.contentSize = CGSizeMake(0, _lastView.frame.origin.y + _lastView.frame.size.height);

Remember that if you are using a proxy you need to do a little trick in your php code:

(PROXY WITHOUT AUTENTICATION EXAMPLE)

<?php
$aContext = array(
    'http' => array(
        'proxy' => 'proxy:8080',
        'request_fulluri' => true,
    ),
);
$cxContext = stream_context_create($aContext);

$sFile = file_get_contents("http://www.google.com", False, $cxContext);

echo $sFile;
?>

export CLASSPATH=/home/appnetix/LOG4J_HOME/log4j-1.2.16.jar

or, if you already have some classpath set

export CLASSPATH=$CLASSPATH:/home/appnetix/LOG4J_HOME/log4j-1.2.16.jar

and, if also you want to include current directory

export CLASSPATH=$CLASSPATH:/home/appnetix/LOG4J_HOME/log4j-1.2.16.jar:.

JS Fiddle Example

$('#userNav').change(function() {
window.location = $(':selected',this).attr('href')
});




<select id="userNav">
<option></option>
<option href="http://google.com">Goolge</option>
<option href="http://duckduckgo.com">Go Go duck</option>
</select>

This works for the href in an option that is selected

Hope this could help Too

$('#selectBox option[value="3"]').attr('selected', true);

Java always takes arguments as a string type...(String args[]) so you need to convert in your desired type.

• Use Integer.parseInt() to convert your string into Interger.
• To print any string you can use System.out.println()

Example :

  int a;
  a = Integer.parseInt(args[0]);

and for Standard Input you can use codes like

  StdIn.readInt();
  StdIn.readString();

For Windows users

I usually upgrade Yarn with Chocolatey.

choco upgrade yarn

You can also check user by id command.

id -u name gives you the id of that user. if the user doesn't exist, you got command return value ($?)1

And as other answers pointed out: if all you want is just to check if the user exists, use if with id directly, as if already checks for the exit code. There's no need to fiddle with strings, [, $? or $():

if id "$1" &>/dev/null; then
    echo 'user found'
else
    echo 'user not found'
fi

(no need to use -u as you're discarding the output anyway)

Also, if you turn this snippet into a function or script, I suggest you also set your exit code appropriately:

#!/bin/bash
user_exists(){ id "$1" &>/dev/null; } # silent, it just sets the exit code
if user_exists "$1"; code=$?; then  # use the function, save the code
    echo 'user found'
else
    echo 'user not found' >&2  # error messages should go to stderr
fi
exit $code  # set the exit code, ultimately the same set by `id`

A lot of answers are recommending the following but if you read through the source of that script, you'll realise it's deprecated.

wget https://bootstrap.pypa.io/ez_setup.py -O - | python

If your pip is also broken, this won't work either.

pip install setuptools

I found I had to run the command from Ensure pip, setuptools, and wheel are up to date, to get pip working again.

python -m pip install --upgrade pip setuptools wheel

As a simple extension to marc_s's answer (the one that has been accepted), this is adjusted to return column count and allow for filtering:

SELECT *
FROM
(

SELECT 
    t.NAME AS TableName,
    s.Name AS SchemaName,
    p.rows AS RowCounts,
    COUNT(DISTINCT c.COLUMN_NAME) as ColumnCount,
    SUM(a.total_pages) * 8 AS TotalSpaceKB, 
    (SUM(a.used_pages) * 8) AS UsedSpaceKB, 
    (SUM(a.total_pages) - SUM(a.used_pages)) * 8 AS UnusedSpaceKB
FROM 
    sys.tables t
INNER JOIN      
    sys.indexes i ON t.OBJECT_ID = i.object_id
INNER JOIN 
    sys.partitions p ON i.object_id = p.OBJECT_ID AND i.index_id = p.index_id
INNER JOIN 
    sys.allocation_units a ON p.partition_id = a.container_id
INNER JOIN
    INFORMATION_SCHEMA.COLUMNS c ON t.NAME = c.TABLE_NAME
LEFT OUTER JOIN 
    sys.schemas s ON t.schema_id = s.schema_id
WHERE 
    t.NAME NOT LIKE 'dt%' 
    AND t.is_ms_shipped = 0
    AND i.OBJECT_ID > 255
GROUP BY 
    t.Name, s.Name, p.Rows
) AS Result

WHERE
    RowCounts > 1000
    AND ColumnCount > 10
ORDER BY 
    UsedSpaceKB DESC

display: none removes the element from the page entirely, and the page is built as though the element were not there at all.

Visibility: hidden leaves the space in the document flow even though you can no longer see it.

This may or may not make a big difference depending on what you are doing.

The best practice is to explicitly list the columns:

Insert Into TableName(col1, col2,col2) Values(?, ?, ?)

Otherwise, your original insert will break if you add another column to your table.

Worked for me -

$scope.downloadFile = function () {
        Resource.downloadFile().then(function (response) {
            var blob = new Blob([response.data], { type: "application/pdf" });
            var objectUrl = URL.createObjectURL(blob);
            window.open(objectUrl);
        },
        function (error) {
            debugger;
        });
    };

Which calls the following from my resource factory-

  downloadFile: function () {
           var downloadRequst = {
                method: 'GET',
                url: 'http://localhost/api/downloadFile?fileId=dfckn4niudsifdh.pdf',
                headers: {
                    'Content-Type': "application/pdf",
                    'Accept': "application/pdf"
                },
                responseType: 'arraybuffer'
            }

            return $http(downloadRequst);
        }

Make sure your API sets the header content type too -

        response.Content.Headers.ContentType = new System.Net.Http.Headers.MediaTypeHeaderValue("application/pdf");
        response.Content.Headers.ContentDisposition = new ContentDispositionHeaderValue("attachment");

Well we don't actually need inspect here.

>>> func = lambda x, y: (x, y)
>>> 
>>> func.__code__.co_argcount
2
>>> func.__code__.co_varnames
('x', 'y')
>>>
>>> def func2(x,y=3):
...  print(func2.__code__.co_varnames)
...  pass # Other things
... 
>>> func2(3,3)
('x', 'y')
>>> 
>>> func2.__defaults__
(3,)

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

you could use something like this

def replace_all(text, dic):
  for i, j in dic.iteritems():
    text = text.replace(i, j)
  return text

This code is not my own and comes from here its a great article and dicusses in depth doing this

I would point you to Wikipedia:

• Symbolic link
• Hard link

A few points:

• Symlinks, unlike hard links, can cross filesystems (most of the time).
• Symlinks can point to directories.
• Hard links point to a file and enable you to refer to the same file with more than one name.
• As long as there is at least one link, the data is still available.

Never, never, never say

if something == True:

Never. It's crazy, since you're redundantly repeating what is redundantly specified as the redundant condition rule for an if-statement.

Worse, still, never, never, never say

if something == False:

You have not. Feel free to use it.

Finally, doing a == None is inefficient. Do a is None. None is a special singleton object, there can only be one. Just check to see if you have that object.
