I had a similar issue recently while trying to link with the pre-built binaries of hdf5 version 1.10.5 on Ubuntu 16.04. None of the solutions suggested here worked for me, and I was using g++ version 9.1. I found that the best solution is to build the hdf5 library from source. Do not use the pre-built binaries since these were built using gcc 4.9! Instead, download the source code archives from the hdf website for your particular distribution and build the library. It is very easy.

You will also need the compression libraries zlib and szip from here and here, respectively, if you do not already have them on your system.

In the first two cases, you simply forgot to actually call the member function (!, it's not a value) std::vector<int>::size like this:

#include <vector>

int main () {
    std::vector<int> v;
    auto size = v.size();
}

Your third call

int size = v.size();

triggers a warning, as not every return value of that function (usually a 64 bit unsigned int) can be represented as a 32 bit signed int.

int size = static_cast<int>(v.size());

would always compile cleanly and also explicitly states that your conversion from std::vector::size_type to int was intended.

Note that if the size of the vector is greater than the biggest number an int can represent, size will contain an implementation defined (de facto garbage) value.

This is a linker issue. Try:

g++ -o test_1 test_1.cpp `pkg-config opencv --cflags --libs`

This should work to compile the source. However, if you recently compiled OpenCV from source, you will meet linking issue in run-time, the library will not be found. In most cases, after compiling libraries from source, you need to do finally:

sudo ldconfig

You can set dbPath in the mongodb.conf file:

storage:
    dbPath: "/path/to/your/database/data/db"

It's a YAML-based configuration file format (since Mongodb 2.6 version), so pay attention no tabs only spaces, and space after ": "

usually this file located in the *nix systems here: /etc/mongodb.conf

So then just run

$ mongod -f /etc/mongodb.conf

And mongod process will start...

(on the Windows something like)

> C:\MongoDB\bin\mongod.exe -f C:\MongoDB\mongod.conf

I also got stucked with same problem so I fixed it like this :

If you are running mongo and nodejs in docker container or in docker compose

so replace localhost with mongo (which is container name in docker in my case) something like this below in your nodejs mongo connection file.

var mongoURI = "mongodb://mongo:27017/<nodejs_container_name>";

I had a similar warning/error/failure when I was simply trying to make an executable from two different object files (main.o and add.o). I was using the command:

gcc -o exec main.o add.o

But my program is a C++ program. Using the g++ compiler solved my issue:

g++ -o exec main.o add.o

I was always under the impression that gcc could figure these things out on its own. Apparently not. I hope this helps someone else searching for this error.

I verified permissions but all was good (mongod:mongod). As I'm working on a large project and from a similar issue in our dev environment where we had a script consuming all available disk space, I could see in the error messages that mongod needs at least 3.7Gb free disk space to run..

I checked my own disk space only to see that less than 2Gb was remaining. After moving / erasing some data I can successfully start mongod again.

Hope this helps ;-)

Add the following line below the [mysqld] section in the mysql config file (my.ini) and restart the apache web server and the mysql service afterwards.

To be able to use std::unordered_map (or one of the other unordered associative containers) with a user-defined key-type, you need to define two things:

1. A hash function; this must be a class that overrides operator() and calculates the hash value given an object of the key-type. One particularly straight-forward way of doing this is to specialize the std::hash template for your key-type.

2. A comparison function for equality; this is required because the hash cannot rely on the fact that the hash function will always provide a unique hash value for every distinct key (i.e., it needs to be able to deal with collisions), so it needs a way to compare two given keys for an exact match. You can implement this either as a class that overrides operator(), or as a specialization of std::equal, or – easiest of all – by overloading operator==() for your key type (as you did already).

The difficulty with the hash function is that if your key type consists of several members, you will usually have the hash function calculate hash values for the individual members, and then somehow combine them into one hash value for the entire object. For good performance (i.e., few collisions) you should think carefully about how to combine the individual hash values to ensure you avoid getting the same output for different objects too often.

A fairly good starting point for a hash function is one that uses bit shifting and bitwise XOR to combine the individual hash values. For example, assuming a key-type like this:

struct Key
{
  std::string first;
  std::string second;
  int         third;

  bool operator==(const Key &other) const
  { return (first == other.first
            && second == other.second
            && third == other.third);
  }
};

Here is a simple hash function (adapted from the one used in the cppreference example for user-defined hash functions):

namespace std {

  template <>
  struct hash<Key>
  {
    std::size_t operator()(const Key& k) const
    {
      using std::size_t;
      using std::hash;
      using std::string;

      // Compute individual hash values for first,
      // second and third and combine them using XOR
      // and bit shifting:

      return ((hash<string>()(k.first)
               ^ (hash<string>()(k.second) << 1)) >> 1)
               ^ (hash<int>()(k.third) << 1);
    }
  };

}

With this in place, you can instantiate a std::unordered_map for the key-type:

int main()
{
  std::unordered_map<Key,std::string> m6 = {
    { {"John", "Doe", 12}, "example"},
    { {"Mary", "Sue", 21}, "another"}
  };
}

It will automatically use std::hash<Key> as defined above for the hash value calculations, and the operator== defined as member function of Key for equality checks.

If you don't want to specialize template inside the std namespace (although it's perfectly legal in this case), you can define the hash function as a separate class and add it to the template argument list for the map:

struct KeyHasher
{
  std::size_t operator()(const Key& k) const
  {
    using std::size_t;
    using std::hash;
    using std::string;

    return ((hash<string>()(k.first)
             ^ (hash<string>()(k.second) << 1)) >> 1)
             ^ (hash<int>()(k.third) << 1);
  }
};

int main()
{
  std::unordered_map<Key,std::string,KeyHasher> m6 = {
    { {"John", "Doe", 12}, "example"},
    { {"Mary", "Sue", 21}, "another"}
  };
}

How to define a better hash function? As said above, defining a good hash function is important to avoid collisions and get good performance. For a real good one you need to take into account the distribution of possible values of all fields and define a hash function that projects that distribution to a space of possible results as wide and evenly distributed as possible.

This can be difficult; the XOR/bit-shifting method above is probably not a bad start. For a slightly better start, you may use the hash_value and hash_combine function template from the Boost library. The former acts in a similar way as std::hash for standard types (recently also including tuples and other useful standard types); the latter helps you combine individual hash values into one. Here is a rewrite of the hash function that uses the Boost helper functions:

#include <boost/functional/hash.hpp>

struct KeyHasher
{
  std::size_t operator()(const Key& k) const
  {
      using boost::hash_value;
      using boost::hash_combine;

      // Start with a hash value of 0    .
      std::size_t seed = 0;

      // Modify 'seed' by XORing and bit-shifting in
      // one member of 'Key' after the other:
      hash_combine(seed,hash_value(k.first));
      hash_combine(seed,hash_value(k.second));
      hash_combine(seed,hash_value(k.third));

      // Return the result.
      return seed;
  }
};

And here’s a rewrite that doesn’t use boost, yet uses good method of combining the hashes:

namespace std
{
    template <>
    struct hash<Key>
    {
        size_t operator()( const Key& k ) const
        {
            // Compute individual hash values for first, second and third
            // http://stackoverflow.com/a/1646913/126995
            size_t res = 17;
            res = res * 31 + hash<string>()( k.first );
            res = res * 31 + hash<string>()( k.second );
            res = res * 31 + hash<int>()( k.third );
            return res;
        }
    };
}

As of today, I tried to get my way through the to create/open lock file: /data/db/mongod.lock errno:13 Permission denied Is a mongod instance already running?, terminating, and tried all the answer posted above to solve this problem, hence nothing worked out by adding

sudo chown -R mongodb:mongodb /data/db

Unless I added my current user permission to the location path by

sudo chown $USER /data/db

Hope this helps someone. Also I just installed Mongo DB on my pi. Cheers!

May be you can find answer here? Equivalent of double-clickable .sh and .bat on Mac?

Usually you can create bash script for Mac OS, where you put similar commands as in batch file. For your case create bash file and put same command, but change back-slashes with regular ones.

Your file will look something like:

#! /bin/bash
java -cp  ".;./supportlibraries/Framework_Core.jar;./supportlibraries/Framework_DataTable.jar;./supportlibraries/Framework_Reporting.jar;./supportlibraries/Framework_Utilities.jar;./supportlibraries/poi-3.8-20120326.jar;PATH_TO_YOUR_SELENIUM_SERVER_FOLDER/selenium-server-standalone-2.19.0.jar" allocator.testTrack

Change folders in path above to relevant one.

Then make this script executable: open terminal and navigate to folder with your script. Then change read-write-execute rights for this file running command:

chmod 755 scriptname.sh

Then you can run it like any other regular script: ./scriptname.sh

or you can run it passing file to bash:

bash scriptname.sh

Ubuntu 18.04LTS: The problem arises when I uninstalled my previous version completely and installed 4.2.6

After hr's of googling, I solved another problem

MongoDB Failing to Start - ***aborting after fassert() failure

I was hopeless about the problem couldn't connect to server, because everything seems ok.

Finally, I decided to restart the operating system and guess what... BINGO

sudo mongo // works like a charm

compiler gives error because when assigning mValue=0 compiler find assignment operator=(int ) for compile time binding but it's not present in the string class. if we type cast following statement to char like mValue=(char)0 then its compile successfully because string class contain operator=(char) method.

They are largely the same, except that:

The alias declaration is compatible with templates, whereas the C style typedef is not.

As others have said, std::max_element() and std::min_element() return iterators, which need to be dereferenced to obtain the value.

The advantage of returning an iterator (rather than just the value) is that it allows you to determine the position of the (first) element in the container with the maximum (or minimum) value.

For example (using C++11 for brevity):

#include <vector>
#include <algorithm>
#include <iostream>

int main()
{
    std::vector<double> v {1.0, 2.0, 3.0, 4.0, 5.0, 1.0, 2.0, 3.0, 4.0, 5.0};

    auto biggest = std::max_element(std::begin(v), std::end(v));
    std::cout << "Max element is " << *biggest
        << " at position " << std::distance(std::begin(v), biggest) << std::endl;

    auto smallest = std::min_element(std::begin(v), std::end(v));
    std::cout << "min element is " << *smallest
        << " at position " << std::distance(std::begin(v), smallest) << std::endl;
}

This yields:

Max element is 5 at position 4
min element is 1 at position 0

Note:

Using std::minmax_element() as suggested in the comments above may be faster for large data sets, but may give slightly different results. The values for my example above would be the same, but the position of the "max" element would be 9 since...

If several elements are equivalent to the largest element, the iterator to the last such element is returned.

This error can be caused by putting the function definitions for a template class in a separate .cpp file. For a template class, the member functions have to be declared in the header file. You can resolve the issue by defining the member functions inline or right after the class definition in the .h file.

For example, instead of putting the function definitions in a .cpp file like for other classes, you could define them inline like this:

template<typename T>
MyClassName {
  void someFunction() {
    // Do something
    ...
  }
  void anotherFunction() {
    // Do something else
    ...
  }
}

Or you could define them after the class definition but in the same file, like this:

template<typename T>
MyClassName {
  void someFunction();
  void anotherFunction();
}

void MyClassName::someFunction() {
  // Do something
  ...
}
void MyClassName::anotherFunction() {
  // Do something else
  ...
}

I just thought I'd share that since no one else seems to have mentioned template classes. This was the cause of the error in my case.

If you're using Windows 7/ 7+.

Here is something you can try.

Check if the installation is proper in CONTROL PANEL of your computer.

Now goto the directory and where you've install the MongoDB. Ideally, it would be in

C:\Program Files\MongoDB\Server\3.6\bin

Then either in the command prompt or in the IDE's terminal. Navigate to the above path ( Ideally your save file) and type

mongod --dbpath

It should work alright!

After (re)-installing the tools package, I got a similar error on a Windows 10 device;

exception in initAndListen: NonExistentPath: Data directory C:\data\db\ not found., terminating

Solution Analog to as explained for the linux systems: simply making the folder is sufficient to be able to start the mongod.exe (mongoDB server).

Thought I might leave it for people that end up here with the same search terms on a Windows device.

For CUDA7.5 these lines work:

sudo ln -s /usr/bin/gcc-4.9 /usr/local/cuda/bin/gcc 
sudo ln -s /usr/bin/g++-4.9 /usr/local/cuda/bin/g++

Find out from netstat which process is running mongodb port (27017)

command:

sudo netstat -tulpn | grep :27017

Output will be:

tcp        0      0 0.0.0.0:27017           0.0.0.0:* 
LISTEN      6432/mongod

In my case "6432" is the pid, it may be different in your case. Then kill that process using following command:

sudo kill <pid>

Thats it!

This happens when the pointer passed to free() is not valid or has been modified somehow. I don't really know the details here. The bottom line is that the pointer passed to free() must be the same as returned by malloc(), realloc() and their friends. It's not always easy to spot what the problem is for a novice in their own code or even deeper in a library. In my case, it was a simple case of an undefined (uninitialized) pointer related to branching.

The free() function frees the memory space pointed to by ptr, which must have been returned by a previous call to malloc(), calloc() or realloc(). Otherwise, or if free(ptr) has already been called before, undefined behavior occurs. If ptr is NULL, no operation is performed. GNU 2012-05-10 MALLOC(3)

char *words; // setting this to NULL would have prevented the issue

if (condition) {
    words = malloc( 512 );

    /* calling free sometime later works here */

    free(words)
} else {

    /* do not allocate words in this branch */
}

/* free(words);  -- error here --
*** glibc detected *** ./bin: munmap_chunk(): invalid pointer: 0xb________ ***/

There are many similar questions here about the related free() and rellocate() functions. Some notable answers providing more details:

*** glibc detected *** free(): invalid next size (normal): 0x0a03c978 ***
*** glibc detected *** sendip: free(): invalid next size (normal): 0x09da25e8 ***
glibc detected, realloc(): invalid pointer

IMHO running everything in a debugger (Valgrind) is not the best option because errors like this are often caused by inept or novice programmers. It's more productive to figure out the issue manually and learn how to avoid it in the future.

The problem is not that you can't forward-declare a template class. Yes, you do need to know all of the template parameters and their defaults to be able to forward-declare it correctly:

namespace std {
  template<class T, class Allocator = std::allocator<T>>
  class list;
}

But to make even such a forward declaration in namespace std is explicitly prohibited by the standard: the only thing you're allowed to put in std is a template specialisation, commonly std::less on a user-defined type. Someone else can cite the relevant text if necessary.

Just #include <list> and don't worry about it.

Oh, incidentally, any name containing double-underscores is reserved for use by the implementation, so you should use something like TEST_H instead of __TEST__. It's not going to generate a warning or an error, but if your program has a clash with an implementation-defined identifier, then it's not guaranteed to compile or run correctly: it's ill-formed. Also prohibited are names beginning with an underscore followed by a capital letter, among others. In general, don't start things with underscores unless you know what magic you're dealing with.

std::unique_ptr has no copy constructor. You create an instance and then ask the std::vector to copy that instance during initialisation.

error: deleted function 'std::unique_ptr<_Tp, _Tp_Deleter>::uniqu
e_ptr(const std::unique_ptr<_Tp, _Tp_Deleter>&) [with _Tp = int, _Tp_D
eleter = std::default_delete<int>, std::unique_ptr<_Tp, _Tp_Deleter> =
 std::unique_ptr<int>]'

The class satisfies the requirements of MoveConstructible and MoveAssignable, but not the requirements of either CopyConstructible or CopyAssignable.

The following works with the new emplace calls.

std::vector< std::unique_ptr< int > > vec;
vec.emplace_back( new int( 1984 ) );

See using unique_ptr with standard library containers for further reading.

typename and class are interchangeable in the basic case of specifying a template:

template<class T>
class Foo
{
};

and

template<typename T>
class Foo
{
};

are equivalent.

Having said that, there are specific cases where there is a difference between typename and class.

The first one is in the case of dependent types. typename is used to declare when you are referencing a nested type that depends on another template parameter, such as the typedef in this example:

template<typename param_t>
class Foo
{
    typedef typename param_t::baz sub_t;
};

The second one you actually show in your question, though you might not realize it:

template < template < typename, typename > class Container, typename Type >

When specifying a template template, the class keyword MUST be used as above -- it is not interchangeable with typename in this case (note: since C++17 both keywords are allowed in this case).

You also must use class when explicitly instantiating a template:

template class Foo<int>;

I'm sure that there are other cases that I've missed, but the bottom line is: these two keywords are not equivalent, and these are some common cases where you need to use one or the other.

Class C {
   int a;
   int b;
   C():b(1),a(2){} //warning, should be C():a(2),b(1)
}

the order is important because if a is initialized before b , and a is depend on b. undefined behavior will appear.

By default std::map (and std::set) use operator< to determine sorting. Therefore, you need to define operator< on your class.

Two objects are deemed equivalent if !(a < b) && !(b < a).

If, for some reason, you'd like to use a different comparator, the third template argument of the map can be changed, to std::greater, for example.

1. Don't write a toString() method. This is not Java. Implement the stream operator for your class.

2. Prefer using the standard algorithms over writing your own loop. In this situation, std::for_each() provides a nice interface to what you want to do.

3. If you must use a loop, but don't intend to change the data, prefer const_iterator over iterator. That way, if you accidently try and change the values, the compiler will warn you.

Then:

std::ostream& operator<<(std::ostream& str,something const& data)
{
    data.print(str)
    return str;
}

void something::print(std::ostream& str) const
{
    std::for_each(table.begin(),table.end(),PrintData(str));
}

Then when you want to print it, just stream the object:

int main()
{
    something    bob;
    std::cout << bob;
}

If you actually need a string representation of the object, you can then use lexical_cast.

int main()
{
    something    bob;

    std::string  rope = boost::lexical_cast<std::string>(bob);
}

The details that need to be filled in.

class somthing
{
    typedef std::map<std::string,std::string>    DataMap;
    struct PrintData
    {
         PrintData(std::ostream& str): m_str(str) {}
         void operator()(DataMap::value_type const& data) const
         {
             m_str << data.first << "=" << data.second << "\n";
         }
         private:  std::ostream& m_str;
    };
    DataMap    table;
    public:
        void something::print(std::ostream& str);
};

First a helper function adapted from the itertools pairwise recipe to produce substrings.

import itertools
def n_wise(iterable, n = 2):
    '''n = 2 -> (s0,s1), (s1,s2), (s2, s3), ...

    n = 3 -> (s0,s1, s2), (s1,s2, s3), (s2, s3, s4), ...'''
    a = itertools.tee(iterable, n)
    for x, thing in enumerate(a[1:]):
        for _ in range(x+1):
            next(thing, None)
    return zip(*a)

Then a function the iterates over substrings, longest first, and tests for membership. (efficiency not considered)

def foo(s1, s2):
    '''Finds the longest matching substring
    '''
    # the longest matching substring can only be as long as the shortest string
    #which string is shortest?
    shortest, longest = sorted([s1, s2], key = len)
    #iterate over substrings, longest substrings first
    for n in range(len(shortest)+1, 2, -1):
        for sub in n_wise(shortest, n):
            sub = ''.join(sub)
            if sub in longest:
                #return the first one found, it should be the longest
                return sub

s = "fdomainster"
t = "exdomainid"
print(foo(s,t))

You asked: 'Are there any applicable differences between dict.items() and dict.iteritems()'

This may help (for Python 2.x):

>>> d={1:'one',2:'two',3:'three'}
>>> type(d.items())
<type 'list'>
>>> type(d.iteritems())
<type 'dictionary-itemiterator'>

You can see that d.items() returns a list of tuples of the key, value pairs and d.iteritems() returns a dictionary-itemiterator.

As a list, d.items() is slice-able:

>>> l1=d.items()[0]
>>> l1
(1, 'one')   # an unordered value!

But would not have an __iter__ method:

>>> next(d.items())
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: list object is not an iterator

As an iterator, d.iteritems() is not slice-able:

>>> i1=d.iteritems()[0]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'dictionary-itemiterator' object is not subscriptable

But does have __iter__:

>>> next(d.iteritems())
(1, 'one')               # an unordered value!

So the items themselves are same -- the container delivering the items are different. One is a list, the other an iterator (depending on the Python version...)

So the applicable differences between dict.items() and dict.iteritems() are the same as the applicable differences between a list and an iterator.

Quoting The C++ FAQ,

[7.8] What's the difference between the keywords struct and class?

The members and base classes of a struct are public by default, while in class, they default to private. Note: you should make your base classes explicitly public, private, or protected, rather than relying on the defaults.

Struct and class are otherwise functionally equivalent.

OK, enough of that squeaky clean techno talk. Emotionally, most developers make a strong distinction between a class and a struct. A struct simply feels like an open pile of bits with very little in the way of encapsulation or functionality. A class feels like a living and responsible member of society with intelligent services, a strong encapsulation barrier, and a well defined interface. Since that's the connotation most people already have, you should probably use the struct keyword if you have a class that has very few methods and has public data (such things do exist in well designed systems!), but otherwise you should probably use the class keyword.

There are two answers above up-to-now and they are both long (and tl;dr too short IMHO), so I write summary from my experience starting to use new java.time library (applicable as noted in other answers to Java version 8+). ISO 8601 sets standard way to write dates: YYYY-MM-DD so the format of date-time is only as below (could be 0, 3, 6 or 9 digits for milliseconds) and no formatting string necessary:

import java.time.Instant;
public static void main(String[] args) {
    String date="2010-10-02T12:23:23Z";
    try {
        Instant myDate = Instant.parse(date);
    } catch (ParseException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}

I did not need it, but as getting year is in code from the question, then:
it is trickier, cannot be done from Instant directly, can be done via Calendar in way of questions Get integer value of the current year in Java and Converting java.time to Calendar but IMHO as format is fixed substring is more simple to use:

myDate.toString().substring(0,4);

IF vertical align won't work use padding. padding-top: 10px; it will shift the text to the bottom or padding-bottom: 10px; to shift the text in the text box to top

adjust the padding size till it suit the size you want. Thats the hack

if (types == UIRemoteNotificationTypeNone) 

will allow you to check only whether notifications are enabled (and don't worry about sounds, badges, notification center, etc.). The first line of code (types & UIRemoteNotificationTypeAlert) will return YES if "Alert Style" is set to "Banners" or "Alerts", and NO if "Alert Style" is set to "None", irrespective of other settings.

Try:

which( !is.na(p), arr.ind=TRUE)

Which I think is just as informative and probably more useful than the output you specified, But if you really wanted the list version, then this could be used:

> apply(p, 1, function(x) which(!is.na(x)) )
[[1]]
[1] 2 3

[[2]]
[1] 4 7

[[3]]
integer(0)

[[4]]
[1] 5

[[5]]
integer(0)

Or even with smushing together with paste:

lapply(apply(p, 1, function(x) which(!is.na(x)) ) , paste, collapse=", ")

The output from which function the suggested method delivers the row and column of non-zero (TRUE) locations of logical tests:

> which( !is.na(p), arr.ind=TRUE)
     row col
[1,]   1   2
[2,]   1   3
[3,]   2   4
[4,]   4   5
[5,]   2   7

Without the arr.ind parameter set to non-default TRUE, you only get the "vector location" determined using the column major ordering the R has as its convention. R-matrices are just "folded vectors".

> which( !is.na(p) )
[1]  6 11 17 24 32

If this error occurs when you want to use a classvariable in a new form, you should put the class definition in the

Formname.Designer.cs

instead of the Formname.cs file.

The only way you should be getting values "out of" an Observable/Subject is with subscribe!

If you're using getValue() you're doing something imperative in declarative paradigm. It's there as an escape hatch, but 99.9% of the time you should NOT use getValue(). There are a few interesting things that getValue() will do: It will throw an error if the subject has been unsubscribed, it will prevent you from getting a value if the subject is dead because it's errored, etc. But, again, it's there as an escape hatch for rare circumstances.

There are several ways of getting the latest value from a Subject or Observable in a "Rx-y" way:

1. Using BehaviorSubject: But actually subscribing to it. When you first subscribe to BehaviorSubject it will synchronously send the previous value it received or was initialized with.
2. Using a ReplaySubject(N): This will cache N values and replay them to new subscribers.
3. A.withLatestFrom(B): Use this operator to get the most recent value from observable B when observable A emits. Will give you both values in an array [a, b].
4. A.combineLatest(B): Use this operator to get the most recent values from A and B every time either A or B emits. Will give you both values in an array.
5. shareReplay(): Makes an Observable multicast through a ReplaySubject, but allows you to retry the observable on error. (Basically it gives you that promise-y caching behavior).
6. publishReplay(), publishBehavior(initialValue), multicast(subject: BehaviorSubject | ReplaySubject), etc: Other operators that leverage BehaviorSubject and ReplaySubject. Different flavors of the same thing, they basically multicast the source observable by funneling all notifications through a subject. You need to call connect() to subscribe to the source with the subject.

Steps to perform the task:

1. First, download and install the compiler.

2. Then, type the C/C++ program and save it.

3. Then, open the command line and change directory to the particular one where the source file is stored, using cd like so:

   cd C:\Documents and Settings\...
   

4. Then, to compile, type in the command prompt:

   gcc sourcefile_name.c -o outputfile.exe
   

5. Finally, to run the code, type:

   outputfile.exe
   

In this specific case, note that bash has a variable called PWD that contains the current directory: $PWD is equivalent to `pwd`. (So do other shells, this is a standard feature.) So you can write your script like this:

#!/bin/bash
until [ "$PWD" = "/" ]; do
  echo "$PWD"
  ls && cd .. && ls 
done

Note the use of double quotes around the variable references. They are necessary if the variable (here, the current directory) contains whitespace or wildcards (\[?*), because the shell splits the result of variable expansions into words and performs globbing on these words. Always double-quote variable expansions "$foo" and command substitutions "$(foo)" (unless you specifically know you have not to).

In the general case, as other answers have mentioned already:

• You can't use whitespace around the equal sign in an assignment: var=value, not var = value
• The $ means “take the value of this variable”, so you don't use it when assigning: var=value, not $var=value.

Compatibility of Python 2/3 for configparser can be solved simply by six library

from six.moves import configparser

Upgrade to PostgreSQL 9.5 or greater. If (not) exists was introduced in version 9.5.

This is BEST solution

Using:

// TO ALL dates
Date.timezoneOffset(-240) // +4 UTC

// Override offset only for THIS date
new Date().timezoneOffset(-180) // +3 UTC

Code:

Date.prototype.timezoneOffset = new Date().getTimezoneOffset();

Date.setTimezoneOffset = function(timezoneOffset) {
  return this.prototype.timezoneOffset = timezoneOffset;
};

Date.getTimezoneOffset = function() {
  return this.prototype.timezoneOffset;
};

Date.prototype.setTimezoneOffset = function(timezoneOffset) {
  return this.timezoneOffset = timezoneOffset;
};

Date.prototype.getTimezoneOffset = function() {
  return this.timezoneOffset;
};

Date.prototype.toString = function() {
  var offsetDate, offsetTime;
  offsetTime = this.timezoneOffset * 60 * 1000;
  offsetDate = new Date(this.getTime() - offsetTime);
  return offsetDate.toUTCString();
};

['Milliseconds', 'Seconds', 'Minutes', 'Hours', 'Date', 'Month', 'FullYear', 'Year', 'Day'].forEach((function(_this) {
  return function(key) {
    Date.prototype["get" + key] = function() {
      var offsetDate, offsetTime;
      offsetTime = this.timezoneOffset * 60 * 1000;
      offsetDate = new Date(this.getTime() - offsetTime);
      return offsetDate["getUTC" + key]();
    };
    return Date.prototype["set" + key] = function(value) {
      var offsetDate, offsetTime, time;
      offsetTime = this.timezoneOffset * 60 * 1000;
      offsetDate = new Date(this.getTime() - offsetTime);
      offsetDate["setUTC" + key](value);
      time = offsetDate.getTime() + offsetTime;
      this.setTime(time);
      return time;
    };
  };
})(this));

Coffee version:

Date.prototype.timezoneOffset = new Date().getTimezoneOffset()


Date.setTimezoneOffset = (timezoneOffset)->
    return @prototype.timezoneOffset = timezoneOffset


Date.getTimezoneOffset = ->
    return @prototype.timezoneOffset


Date.prototype.setTimezoneOffset = (timezoneOffset)->
    return @timezoneOffset = timezoneOffset


Date.prototype.getTimezoneOffset = ->
    return @timezoneOffset


Date.prototype.toString = ->
    offsetTime = @timezoneOffset * 60 * 1000
    offsetDate = new Date(@getTime() - offsetTime)
    return offsetDate.toUTCString()


[
    'Milliseconds', 'Seconds', 'Minutes', 'Hours',
    'Date', 'Month', 'FullYear', 'Year', 'Day'
]
.forEach (key)=>
    Date.prototype["get#{key}"] = ->
        offsetTime = @timezoneOffset * 60 * 1000
        offsetDate = new Date(@getTime() - offsetTime)
        return offsetDate["getUTC#{key}"]()

    Date.prototype["set#{key}"] = (value)->
        offsetTime = @timezoneOffset * 60 * 1000
        offsetDate = new Date(@getTime() - offsetTime)
        offsetDate["setUTC#{key}"](value)
        time = offsetDate.getTime() + offsetTime
        @setTime(time)
        return time

Just in case if it could help someone like me.

Based on the Official website and the Accepted answer, I made a code using C# that uses System.Data.SQLite NuGet package.

This code also preserves the Primary key and Foreign key.

CODE in C#:

void RemoveColumnFromSqlite (string tableName, string columnToRemove) {
 try {
    var mSqliteDbConnection = new SQLiteConnection ("Data Source=db_folder\\MySqliteBasedApp.db;Version=3;Page Size=1024;");
    mSqliteDbConnection.Open ();             
    // Reads all columns definitions from table
    List<string> columnDefinition = new List<string> ();
    var mSql = $"SELECT type, sql FROM sqlite_master WHERE tbl_name='{tableName}'";
    var mSqliteCommand = new SQLiteCommand (mSql, mSqliteDbConnection);
    string sqlScript = "";
    using (mSqliteReader = mSqliteCommand.ExecuteReader ()) {
       while (mSqliteReader.Read ()) {
          sqlScript = mSqliteReader["sql"].ToString ();
          break;
       }
    }
    if (!string.IsNullOrEmpty (sqlScript)) {
       // Gets string within first '(' and last ')' characters
       int firstIndex = sqlScript.IndexOf ("(");
       int lastIndex = sqlScript.LastIndexOf (")");
       if (firstIndex >= 0 && lastIndex <= sqlScript.Length - 1) {
          sqlScript = sqlScript.Substring (firstIndex, lastIndex - firstIndex + 1);
       }
       string[] scriptParts = sqlScript.Split (new string[] { "," }, StringSplitOptions.RemoveEmptyEntries);
       foreach (string s in scriptParts) {
          if (!s.Contains (columnToRemove)) {
             columnDefinition.Add (s);
          }
       }
    }
    string columnDefinitionString = string.Join (",", columnDefinition);
    // Reads all columns from table
    List<string> columns = new List<string> ();
    mSql = $"PRAGMA table_info({tableName})";
    mSqliteCommand = new SQLiteCommand (mSql, mSqliteDbConnection);
    using (mSqliteReader = mSqliteCommand.ExecuteReader ()) {
       while (mSqliteReader.Read ()) columns.Add (mSqliteReader["name"].ToString ());
    }
    columns.Remove (columnToRemove);
    string columnString = string.Join (",", columns);
    mSql = "PRAGMA foreign_keys=OFF";
    mSqliteCommand = new SQLiteCommand (mSql, mSqliteDbConnection);
    int n = mSqliteCommand.ExecuteNonQuery ();
    // Removes a column from the table
    using (SQLiteTransaction tr = mSqliteDbConnection.BeginTransaction ()) {
       using (SQLiteCommand cmd = mSqliteDbConnection.CreateCommand ()) {
          cmd.Transaction = tr;
          string query = $"CREATE TEMPORARY TABLE {tableName}_backup {columnDefinitionString}";
          cmd.CommandText = query;
          cmd.ExecuteNonQuery ();
          cmd.CommandText = $"INSERT INTO {tableName}_backup SELECT {columnString} FROM {tableName}";
          cmd.ExecuteNonQuery ();
          cmd.CommandText = $"DROP TABLE {tableName}";
          cmd.ExecuteNonQuery ();
          cmd.CommandText = $"CREATE TABLE {tableName} {columnDefinitionString}";
          cmd.ExecuteNonQuery ();
          cmd.CommandText = $"INSERT INTO {tableName} SELECT {columnString} FROM {tableName}_backup;";
          cmd.ExecuteNonQuery ();
          cmd.CommandText = $"DROP TABLE {tableName}_backup";
          cmd.ExecuteNonQuery ();
       }
       tr.Commit ();
    }
    mSql = "PRAGMA foreign_keys=ON";
    mSqliteCommand = new SQLiteCommand (mSql, mSqliteDbConnection);
    n = mSqliteCommand.ExecuteNonQuery ();

I've solved the endless fight with Google Chrome with the use of random characters. When you always render autocomplete with random string, it will never remember anything.

<input name="name" type="text" autocomplete="rutjfkde">

Hope that it will help to other people.

You're looking for the /Y switch.

ctrl-ww Could be useful when you have limited tabs open. But could get annoying when you have too many tabs open.

I type in :NERDTree again to get the focus back on NERDTree tab instantly wherever my cursor's focus is. Hope that helps

lvalue means "left value" -- it should be assignable. You cannot change the value of text since it is an array, not a pointer.

Either declare it as char pointer (in this case it's better to declare it as const char*):

const char *text;
if(number == 2) 
    text = "awesome"; 
else 
    text = "you fail";

Or use strcpy:

char text[60];
if(number == 2) 
    strcpy(text, "awesome"); 
else 
    strcpy(text, "you fail");

For streaming protocols such as TCP, you can pretty much set your buffer to any size. That said, common values that are powers of 2 such as 4096 or 8192 are recommended.

If there is more data then what your buffer, it will simply be saved in the kernel for your next call to recv.

Yes, you can keep growing your buffer. You can do a recv into the middle of the buffer starting at offset idx, you would do:

recv(socket, recv_buffer + idx, recv_buffer_size - idx, 0);

You can create a large array and then copy it to a new array using System.arrayCopy

        int contentLength = 100000000;
        byte[] byteArray = new byte[contentLength];

        BufferedInputStream inputStream = new BufferedInputStream(connection.getInputStream());
        while ((bytesRead = inputStream.read()) != -1)
        {
            byteArray[count++] = (byte)bytesRead;
        }

        byte[] destArray = new byte[count];
        System.arraycopy(byteArray, 0, destArray , 0, count);

destArray will contain the information you want

Here is the simple solution

You can use typescript iterators for this

import {Component} from 'angular2/core';
declare var Symbol;
@Component({
    selector: 'my-app',
    template:`<div>
    <h4>Iterating an Object using Typescript Symbol</h4><br>
Object is : <p>{{obj | json}}</p>
</div>
============================<br>
Iterated object params are:
<div *ngFor="#o of obj">
{{o}}
</div>

`
})
export class AppComponent {
  public obj: any = {
    "type1": ["A1", "A2", "A3","A4"],
    "type2": ["B1"],
    "type3": ["C1"],
    "type4": ["D1","D2"]
  };

  constructor() {
    this.obj[Symbol.iterator] =  () => {
          let i =0;

          return {
            next: () => {
              i++;
              return {
                  done: i > 4?true:false,
                  value: this.obj['type'+i]
              }
            }
          }
    };
  }
}

With iOS 8, Xcode 6, iTunes Connect and TestFlight you don't need UDIDs and Ad Hocs anymore. You will just need an Apple ID from your beta tester. Right now you can only beta test your app with 25 internal testers, but soon 1000 external testers will be available too. This blog post shows you how to setup a beta test with internal testers.

BigDecimal bd = new BigDecimal(300000);

NumberFormat formatter = NumberFormat.getInstance(new Locale("en_US"));

System.out.println(formatter.format(bd.longValue()));

EDIT

To get custom grouping separator such as space, do this:

DecimalFormatSymbols symbols = DecimalFormatSymbols.getInstance();
symbols.setGroupingSeparator(' ');

DecimalFormat formatter = new DecimalFormat("###,###.##", symbols);
System.out.println(formatter.format(bd.longValue()));

I created a ~/.wgetrc file with the following content (obtained from askapache.com but with a newer user agent, because otherwise it didn’t work always):

header = Accept-Language: en-us,en;q=0.5
header = Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
header = Connection: keep-alive
user_agent = Mozilla/5.0 (X11; Fedora; Linux x86_64; rv:40.0) Gecko/20100101 Firefox/40.0
referer = /
robots = off

Now I’m able to download from most (all?) file-sharing (streaming video) sites.

In xaml

<TextBlock Text="{Binding CelsiusTemp}" />

In ViewModel, this way setting the value also works:

 public string CelsiusTemp
        {
            get { return string.Format("{0}°C", _CelsiusTemp); }
            set
            {
                value = value.Replace("°C", "");
              _CelsiusTemp = value;
            }
        }

I found this maven repo where you could download from directly a zip file containing all the jars you need.

• https://maven.springframework.org/release/org/springframework/spring/
• https://repo.spring.io/release/org/springframework/spring/

Alternate solution: Maven

The solution I prefer is using Maven, it is easy and you don't have to download each jar alone. You can do it with the following steps:

1. Create an empty folder anywhere with any name you prefer, for example spring-source

2. Create a new file named pom.xml

3. Copy the xml below into this file

4. Open the spring-source folder in your console

5. Run mvn install

6. After download finished, you'll find spring jars in /spring-source/target/dependencies

   <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

   </project>
   

Also, if you need to download any other spring project, just copy the dependency configuration from its corresponding web page.

For example, if you want to download Spring Web Flow jars, go to its web page, and add its dependency configuration to the pom.xml dependencies, then run mvn install again.

<dependency>
  <groupId>org.springframework.webflow</groupId>
  <artifactId>spring-webflow</artifactId>
  <version>2.3.2.RELEASE</version>
</dependency>

Solved! The call build job: project, parameters: params fails with an error java.lang.UnsupportedOperationException: must specify $class with an implementation of interface java.util.List when params = [:]. Replacing it with params = null solved the issue. Here the working code below.

    step ([
        $class: 'CopyArtifact',
        projectName: projectName,

        flatten: true
    ]);
}

Here is a Plunker handling any situation above proposition do not handle.
By using $formatters and $parsers pipeline and avoiding type="number"

And here is the explanation of problems/solutions (also available in the Plunker) :

/*
 *
 * Limit input text for floating numbers.
 * It does not display characters and can limit the Float value to X numbers of integers and X numbers of decimals.
 * min and max attributes can be added. They can be Integers as well as Floating values.
 *
 * value needed    |    directive
 * ------------------------------------
 * 55              |    max-integer="2"
 * 55.55           |    max-integer="4" decimal="2" (decimals are substracted from total length. Same logic as database NUMBER type)
 *
 *
 * Input type="number" (HTML5)
 *
 * Browser compatibility for input type="number" :
 * Chrome : - if first letter is a String : allows everything
 *          - if first letter is a Integer : allows [0-9] and "." and "e" (exponential)
 * Firefox : allows everything
 * Internet Explorer : allows everything
 *
 * Why you should not use input type="number" :
 * When using input type="number" the $parser pipeline of ngModel controller won't be able to access NaN values.
 * For example : viewValue = '1e'  -> $parsers parameter value = "".
 * This is because undefined values are not allowes by default (which can be changed, but better not do it)
 * This makes it impossible to modify the view and model value; to get the view value, pop last character, apply to the view and return to the model.
 *
 * About the ngModel controller pipelines :
 * view value -> $parsers -> model value
 * model value -> $formatters -> view value
 *
 * About the $parsers pipeline :
 * It is an array of functions executed in ascending order.
 * When used with input type="number" :
 * This array has 2 default functions, one of them transforms the datatype of the value from String to Number.
 * To be able to change the value easier (substring), it is better to have access to a String rather than a Number.
 * To access a String, the custom function added to the $parsers pipeline should be unshifted rather than pushed.
 * Unshift gives the closest access to the view.
 *
 * About the $formatters pipeline :
 * It is executed in descending order
 * When used with input type="number"
 * Default function transforms the value datatype from Number to String.
 * To access a String, push to this pipeline. (push brings the function closest to the view value)
 *
 * The flow :
 * When changing ngModel where the directive stands : (In this case only the view has to be changed. $parsers returns the changed model)
 *     -When the value do not has to be modified :
 *     $parsers -> $render();
 *     -When the value has to be modified :
 *     $parsers(view value) --(does view needs to be changed?) -> $render();
 *       |                                  |
 *       |                     $setViewValue(changedViewValue)
 *       |                                  |
 *       --<-------<---------<--------<------
 *
 * When changing ngModel where the directive does not stand :
 *     - When the value does not has to be modified :
 *       -$formatters(model value)-->-- view value
 *     -When the value has to be changed
 *       -$formatters(model vale)-->--(does the value has to be modified) -- (when loop $parsers loop is finished, return modified value)-->view value
 *                                              |
 *                                  $setViewValue(notChangedValue) giving back the non changed value allows the $parsers handle the 'bad' value
 *                                               |                  and avoids it to think the value did not changed
 *                Changed the model <----(the above $parsers loop occurs)
 *
 */

Strings aren't value types since they can be huge, and need to be stored on the heap. Value types are (in all implementations of the CLR as of yet) stored on the stack. Stack allocating strings would break all sorts of things: the stack is only 1MB for 32-bit and 4MB for 64-bit, you'd have to box each string, incurring a copy penalty, you couldn't intern strings, and memory usage would balloon, etc...

(Edit: Added clarification about value type storage being an implementation detail, which leads to this situation where we have a type with value sematics not inheriting from System.ValueType. Thanks Ben.)

here is the perfect way...

private void func_trd(String sender)

    try
    {
        imgh.LoadImages_R_Randomiz(this, "01", groupBox, randomizerB.Value); // normal code

        {
            ExecuteInForeground(sender);
        };

        Thread nt = new Thread(ts);
        nt.IsBackground = true;

        nt.Start();

    }
    catch (Exception)
    {

private void ExecuteInForeground(string name)

     //whatever ur function
    MessageBox.Show(name);
}

Not sure if it is still relevant but I came across this problem, my situation i just needed to return a dictionary of the changes for all nested dictionaries etc etc. Could not find a good solution out there but I did end up writing a simple function to do this. Hope this helps,

^ is the bitwise exclusive OR (XOR) operator in Java (and many other languages). It is not used for exponentiation. For that, you must use Math.pow.

You can execute an .exe from a Windows service very well in Windows XP. I have done it myself in the past.

You need to make sure you had checked the option "Allow to interact with the Desktop" in the Windows service properties. If that is not done, it will not execute.

I need to check in Windows 7 or Vista as these versions requires additional security privileges so it may throw an error, but I am quite sure it can be achieved either directly or indirectly. For XP I am certain as I had done it myself.

Div of style, position:absolute;bottom:5px;width:100%; is working, But it required more scrollup situation.

window.onscroll = function() {
    var v = document.getElementById("copyright");
    v.style.position = "fixed";
    v.style.bottom = "5px";
}

$( "#myId option:selected" ).text(); will give you the text that you selected in the drop down element. either way you can change it to .val(); to get the value of it . check the below coding

<select id="myId">
    <option value="1">Mr</option>
    <option value="2">Mrs</option>
    <option value="3">Ms</option>`
    <option value="4">Dr</option>
    <option value="5">Prof</option>
</select>

You can specify border separately for all borders, for example:

#testdiv{
  border-left: 1px solid #000;
  border-right: 2px solid #FF0;
}

You can also specify the look of the border, and use separate style for the top, right, bottom and left borders. for example:

#testdiv{
  border: 1px #000;
  border-style: none solid none solid;
}

For those arriving here from google, I've eventually come across this SO question, and this specific answer solved my problem. I've contacted Microsoft for the hotfix through the live chat on support.microsoft.com and they sent me a link to the hotfix by email.

This can be done with lodash _.tail and _.dropRight:

var fruits = ["Banana", "Orange", "Apple", "Mango"];_x000D_
console.log(_.dropRight(_.tail(fruits)));

<script src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.11/lodash.min.js"></script>

The above mentioned answers are correct but I am simplifying it for noobs like me.Go to your project's pom file. Add a new property exec.mainClass and give its value as the class which contains your main method. For me it was DriverClass in mainpkg. Change it as per your project.

Having done this navigate to the folder that contains your project's pom.xml and run this on the command prompt mvn exec:java. This should call the main method.

You can do get id value by using

test_alert = $('#myDiv').val();_x000D_
alert(test_alert);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<div id="myDiv"><p>Some Text</p></div>

 where c.FullName.Contains("string")

Max value for a particular column of a dataframe can be achieved by using -

your_max_value = df.agg({"your-column": "max"}).collect()[0][0]

I've modified an open-source program called "dskwipe" in order to pull this disk information out of it. Dskwipe is written in C, and you can pull this function out of it. The binary and source are available here: dskwipe 0.3 has been released

The returned information will look something like this:

Device Name                         Size Type      Partition Type
------------------------------ --------- --------- --------------------
\\.\PhysicalDrive0               40.0 GB Fixed
\\.\PhysicalDrive1               80.0 GB Fixed
\Device\Harddisk0\Partition0     40.0 GB Fixed
\Device\Harddisk0\Partition1     40.0 GB Fixed     NTFS
\Device\Harddisk1\Partition0     80.0 GB Fixed
\Device\Harddisk1\Partition1     80.0 GB Fixed     NTFS
\\.\C:                           80.0 GB Fixed     NTFS
\\.\D:                            2.1 GB Fixed     FAT32
\\.\E:                           40.0 GB Fixed     NTFS

You can use this :

$this->db->select('*');
$this->db->from('mytable');
$this->db->where(name,'Joe');
$bind = array('boss', 'active');
$this->db->where_in('status', $bind);

As an experiment, I made a post-commit hook that stores information about the currently checked out branch in the commit metadata. I also slightly modified gitk to show that information.

You can check it out here: https://github.com/pajp/branch-info-commits

The exception occurred due to the fact that any of the inner classes or other referenced classes didn't implement the serializable implementation. So make sure that all the referenced classes must implement the serializable implementation.

Rename the Column by doing the following:

dataTable.Columns["ColumnName"].ColumnName = "newColumnName";

Hoodaticus's solution was perfect, thank you, but I also needed it to be re-runnable and found this way to check if it had been done...

IF EXISTS(SELECT * FROM information_schema.columns 
           WHERE table_name='myTable' AND column_name='myColumn' 
             AND Table_schema='myDBO' AND column_default IS NULL) 
BEGIN 
  ALTER TABLE [myDBO].[myTable] ADD DEFAULT 0 FOR [myColumn] --Hoodaticus
END

This answer is obsolete. Technology has moved on. Unless you're working with legacy systems see Joel's answer.

There is no string concatenation operator in EL. If you don't need the concatenated string to pass into some other operation, just put these expressions next to each other:

${value}${(empty value)? 'none' : ' enabled'}

<mvc:resources mapping="/resources/**"
               location="/, classpath:/WEB-INF/public-resources/"
               cache-period="10000" />

Put the resources under: src/main/webapp/images/logo.png and then access them via /resources/images/logo.png.

In the war they will be then located at images/logo.png. So the first location (/) form mvc:resources will pick them up.

The second location (classpath:/WEB-INF/public-resources/) in mvc:resources (looks like you used some roo based template) can be to expose resources (for example js-files) form jars, if they are located in the directory WEB-INF/public-resources in the jar.

I had same issue with the following version 12.0.3:

Could not load file or assembly 'Newtonsoft.Json, Version=12.0.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed' or one of its dependencies. The system cannot find the file specified.

This issue was only in my Test project (xUnit) and was caused by lack of newtonsoft.json in this project.

What is important, I was testing code from another project where library was attached and works properly.

$sn = 0;//increment the serial number, then add the sn to job
for($x = 0; $x<20; $x++)
{
$sn++;
$added_date = "10/10/10";
$job_title = "new job";
$salary = $sn*1000;
$cd = "27/10/2017";//the closing date
$ins = "some institution";//the institution for the vacancy 
$notes = "some notes here";//any notes about the jobs

$sn_div = "<div class='sn_div'>".$sn."</div>";
$ad_div = "<div class='ad_div'>".$added_date."</div>";
$job_div = "<div class='job_div'>".$job_title."</div>";
$salary_div = "<div class='salary_div'>".$salary."</div>";
$cd_div = "<div class='cd_div'>".$cd."</div>";//cd means closing date
$ins_div = "<div class='ins_div'>".$ins."</div>";//ins means institution
$notes_div = "<div class='notes_div'>".$notes."</div>";


/*erroneous line*/$job_no = "job"+$sn;//to create the job rows
$$job_no = "<div class='job_wrapper'>".$sn_div.$ad_div.$job_div.$salary_div.$cd_div.$ins_div.$notes_div."</div>";

echo $$job_no;//and then echo each job

}

that's the code I had which looped and created new html div elements. The code worked fine and the elements were formed, but i got the same warning in the error_log.

After reading the useful other answers, I figured that I was summing up a string and a number in the erroneous line. So I changed the code at that line to

/*erroneous line*/$job_no = "job"&&$sn;//this is the new variable that will create the job rows

Now the code works as earlier but with no warnings this time. Hope this example would be useful to someone.

If you want to ignore the Edittext from the starting of activity, android:focusable and android:focusableInTouchMode will help you inshallah.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/linearLayout7" android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:focusable="true" android:focusableInTouchMode="true">

This LinearLayout with your Edittext.

Format from 1000000.2 to 1 000 000,20

private static final DecimalFormat DF = new DecimalFormat();

public static String toCurrency(Double d) {
    if (d == null || "".equals(d) || "NaN".equals(d)) {
        return " - ";
    }
    BigDecimal bd = new BigDecimal(d);
    bd = bd.setScale(2, BigDecimal.ROUND_HALF_UP);
    DecimalFormatSymbols symbols = DF.getDecimalFormatSymbols();
    symbols.setGroupingSeparator(' ');
    String ret = DF.format(bd) + "";
    if (ret.indexOf(",") == -1) {
        ret += ",00";
    }
    if (ret.split(",")[1].length() != 2) {
        ret += "0";
    }
    return ret;
}

So basically, in jquery what we can do is to load href attribute using the load function. This way we can use the url in <a> tag and load that in modal-body.

<a  href='/site/login' class='ls-modal'>Login</a>

//JS script
$('.ls-modal').on('click', function(e){
  e.preventDefault();
  $('#myModal').modal('show').find('.modal-body').load($(this).attr('href'));
});

this is a select command

   FROM
    user
WHERE
    application_key = 'dsfdsfdjsfdsf'
        AND email NOT LIKE '%applozic.com'
        AND email NOT LIKE '%gmail.com'
        AND email NOT LIKE '%kommunicate.io';

this update command

 UPDATE user
    SET email = null
    WHERE application_key='dsfdsfdjsfdsf' and  email not like '%applozic.com' 
    and email not like '%gmail.com'  and email not like '%kommunicate.io';

Here is a command that gives you all tracking branches (configured for 'pull'), see:

$ git branch -vv
  main   aaf02f0 [main/master: ahead 25] Some other commit
* master add0a03 [jdsumsion/master] Some commit

You have to wade through the SHA and any long-wrapping commit messages, but it's quick to type and I get the tracking branches aligned vertically in the 3rd column.

If you need info on both 'pull' and 'push' configuration per branch, see the other answer on git remote show origin.

Update

Starting in git version 1.8.5 you can show the upstream branch with git status and git status -sb

>>> nums = [1, 2, 3, 4, 5]    
>>> min(map((lambda t: ((float(t[0])/t[1]), t)), ((x, y) for x in nums for y in nums)))[1]
(1, 5)

The read(1) utility along with output redirection of the ls(1) command will do what you want.

Here's one: (check out http://hongouru.blogspot.ie/2011/09/c-ocr-optical-character-recognition.html or http://www.codeproject.com/Articles/41709/How-To-Use-Office-2007-OCR-Using-C for more info)

using MODI;
static void Main(string[] args)
{
    DocumentClass myDoc = new DocumentClass();
    myDoc.Create(@"theDocumentName.tiff"); //we work with the .tiff extension
    myDoc.OCR(MiLANGUAGES.miLANG_ENGLISH, true, true);

    foreach (Image anImage in myDoc.Images)
    {
        Console.WriteLine(anImage.Layout.Text); //here we cout to the console.
    }
}

Just loop over the elements in your array.

Ex:

for(int i=0; numOfElements > i; i++)
{
outputWriter.write(array[i]);
}
//finish up down here

Minted, whether from GitHub or CTAN, the Comprehensive TeX Archive Network, works in Overleaf, TeX Live and MiKTeX.

It requires the installation of the Python package Pygments; this is explained in the documentation in either source above. Although Pygments brands itself as a Python syntax highlighter, Minted guarantees the coverage of hundreds of other languages.

Example:

\documentclass{article}
\usepackage{minted}
\begin{document}

\begin{minted}[mathescape, linenos]{python}

# Note: $\pi=\lim_{n\to\infty}\frac{P_n}{d}$
title = "Hello World"

sum = 0
for i in range(10):
 sum += i

\end{minted}

\end{document}

Output:

You could add an OUTPUT parameter to test2, and set it to the new id straight after the INSERT using:

SELECT @NewIdOutputParam = SCOPE_IDENTITY()

Then in test1, retrieve it like so:

DECLARE @NewId INTEGER
EXECUTE test2 @NewId OUTPUT
-- Now use @NewId as needed

Try creating a new service and calling it. The processing can be done there, and returned back.

http://code.msdn.microsoft.com/windowsazure/WCF-Azure-AJAX-Calculator-4cf3099e

function makeCall(operation){
    var n1 = document.getElementById("num1").value;
    var n2 = document.getElementById("num2").value;
if(n1 && n2){

        // Instantiate a service proxy
        var proxy = new Service();

        // Call correct operation on vf cproxy       
        switch(operation){

            case "gridOne":
                proxy.Calculate(AjaxService.Operation.getWeather, n1, n2,
 onSuccess, onFail, null);

****HTML CODE****
<p>Major City: <input type="text" id="num1" onclick="return num1_onclick()"

<input id="btnDivide" type="button" onclick="return makeCall('gridOne');" 

Step 1 - Rename the project

1. Click on the project you want to rename in the "Project navigator" in the left panel of the Xcode window.
2. In the right panel, select the "File inspector", and the name of your project should be found under "Identity and Type". Change it to your new name.
3. When the dialog asks whether to rename or not rename the project's content items, click "Rename". Say yes to any warning about uncommitted changes.

Step 2 - Rename the scheme

1. At the top of the window, next to the "Stop" button, there is a scheme for your product under its old name; click on it, then choose "Manage Schemes…".
2. Click on the old name in the scheme and it will become editable; change the name and click "Close".

Step 3 - Rename the folder with your assets

1. Quit Xcode. Rename the master folder that contains all your project files.
2. In the correctly-named master folder, beside your newly-named .xcodeproj file, there is probably a wrongly-named OLD folder containing your source files. Rename the OLD folder to your new name (if you use Git, you could run git mv oldname newname so that Git recognizes this is a move, rather than deleting/adding new files).
3. Re-open the project in Xcode. If you see a warning "The folder OLD does not exist", dismiss the warning. The source files in the renamed folder will be grayed out because the path has broken.
4. In the "Project navigator" in the left-hand panel, click on the top-level folder representing the OLD folder you renamed.
5. In the right-hand panel, under "Identity and Type", change the "Name" field from the OLD name to the new name.
6. Just below that field is a "Location" menu. If the full path has not corrected itself, click on the nearby folder icon and choose the renamed folder.

Step 4 - Rename the Build plist data

1. Click on the project in the "Project navigator" on the left, and in the main panel select "Build Settings".
2. Search for "plist" in the settings.
3. In the Packaging section, you will see Info.plist and Product Bundle Identifier.
4. If there is a name entered in Info.plist, update it.
5. Do the same for Product Bundle Identifier, unless it is utilizing the ${PRODUCT_NAME} variable. In that case, search for "product" in the settings and update Product Name. If Product Name is based on ${TARGET_NAME}, click on the actual target item in the TARGETS list on the left of the settings pane and edit it, and all related settings will update immediately.
6. Search the settings for "prefix" and ensure that Prefix Header's path is also updated to the new name.
7. If you use SwiftUI, search for "Development Assets" and update the path.

Step 5 - Repeat step 3 for tests (if you have them)

Step 6 - Repeat step 3 for core data if its name matches project name (if you have it)

Step 7 - Clean and rebuild your project

1. Command + Shift + K to clean
2. Command + B to build

I think this only happens when you have 'Preserve log' checked and you are trying to view the response data of a previous request after you have navigated away.

For example, I viewed the Response to loading this Stack Overflow question. You can see it.

The second time, I reloaded this page but didn't look at the Headers or Response. I navigated to a different website. Now when I look at the response, it shows 'Failed to load response data'.

This is a known issue, that's been around for a while, and debated a lot. However, there is a workaround, in which you pause on onunload, so you can view the response before it navigates away, and thereby doesn't lose the data upon navigating away.

window.onunload = function() { debugger; }

Based on the comments above, here is a simple test:

isunset() { [[ "${!1}" != 'x' ]] && [[ "${!1-x}" == 'x' ]] && echo 1; }
isset()   { [ -z "$(isunset "$1")" ] && echo 1; }

Example:

$ unset foo; [[ $(isunset foo) ]] && echo "It's unset" || echo "It's set"
It's unset
$ foo=     ; [[ $(isunset foo) ]] && echo "It's unset" || echo "It's set"
It's set
$ foo=bar  ; [[ $(isunset foo) ]] && echo "It's unset" || echo "It's set"
It's set

Check this:

a = [*(1..10), :top, *10.downto( 1 )]

Yes. You can put comments in a JSON file.

{
    "": "Location to post to",
    "postUrl": "https://example.com/upload/",

    "": "Username for basic auth",
    "username": "joebloggs",

    "": "Password for basic auth (note this is in clear, be sure to use HTTPS!",
    "password": "bloejoggs"
}

A comment is simply a piece of text describing the purpose of a block of code or configuration. And because you can specify keys multiple times in JSON, you can do it like this. It's syntactically correct and the only tradeoff is you'll have an empty key with some garbage value in your dictionary (which you could trim...)

I saw this question years and years ago but I only just saw this done like this in a project I'm working on and I thought this was a really clean way to do it. Enjoy!

If you mean VB 6, that would be Private Sub Class_Initialize().

http://msdn.microsoft.com/en-us/library/55yzhfb2(VS.80).aspx

If you mean VB.NET it is Public Sub New() or Shared Sub New().

Please remove e.preventDefault(), because event.cancelable of touchmove is false. So you can't call this method.

dir(instance)
# or (same value)
instance.__dir__()
# or
instance.__dict__

Then you can test what type is with type() or if is a method with callable().

what isn't working about it? here's a tested version:

String.prototype.isValidDate = function()   {

    const match = this.match(/^([0-9]{2})\/([0-9]{2})\/([0-9]{4})$/);
    if (!match || match.length !== 4) {
        return false
    }

    const test = new Date(match[3], match[1] - 1, match[2]);

    return (
        (test.getMonth() == match[1] - 1) &&
        (test.getDate() == match[2]) &&
        (test.getFullYear() == match[3])
    );
}

var date = '12/08/1984'; // Date() is 'Sat Dec 08 1984 00:00:00 GMT-0800 (PST)'
alert(date.isValidDate() ); // true

Adds a fading gradient to an overflowing HTML table element to better indicate there is more content to be scrolled.

I also encountered the same problem, I was such a solution.

First of all to be clear: provisioning profile must choose "Automatic" to debug.

If provisioning profile is "adhoc", then you can not debug, and can only export the ".ipa" file, import to iTunes for installation.

After I changed

defaultConfig {
    applicationId "com.example.bocheng.myapplication"
    minSdkVersion 15
    targetSdkVersion 'L' #change this to 19
    versionCode 1
    versionName "1.0"
}

in build.gradle file.

it works

When using MVC, try using ViewBag. The best way to take input from textbox and displaying in View.

If you want all packages in that repository, use ... to signify that, like:

go get code.google.com/p/go.text/...

In that example, e is just a parameter for that function, but it's the event object that gets passed in through it.

try this

INSERT INTO exampleTbl VALUES('he doesn''t work for me')

Sub Results2()

    Dim rCell As Range
    Dim shSource As Worksheet
    Dim shDest As Worksheet
    Dim lCnt As Long

    Set shSource = ThisWorkbook.Sheets("Sheet1")
    Set shDest = ThisWorkbook.Sheets("Sheet2")

    For Each rCell In shSource.Range("A1", shSource.Cells(shSource.Rows.Count, 1).End(xlUp)).Cells
        lCnt = lCnt + 1
        shDest.Range("A4").Offset(0, lCnt * 4).Formula = "=" & rCell.Address(False, False, , True) & "+" & rCell.Offset(0, 1).Address(False, False, , True)
    Next rCell

End Sub

This loops through column A of sheet1 and creates a formula in sheet2 for every cell. To find the last cell in Sheet1, I start at the bottom (shSource.Rows.Count) and .End(xlUp) to get the last cell in the column that's not blank.

To create the elements of the formula, I use the Address property of the cell on Sheet. I'm using three of the arguments to Address. The first two are RowAbsolute and ColumnAbsolute, both set to false. I don't care about the third argument, but I set the fourth argument (External) to True so that it includes the sheet name.

I prefer to go from Source to Destination rather than the other way. But that's just a personal preference. If you want to work from the destination,

Sub Results3()

    Dim i As Long, lCnt As Long
    Dim sh As Worksheet

    lCnt = Application.WorksheetFunction.CountA(ThisWorkbook.Sheets("Sheet1").Columns(1))
    Set sh = ThisWorkbook.Sheets("Sheet2")

    Const sSOURCE As String = "Sheet1!"

    For i = 1 To lCnt
        sh.Range("A1").Offset(0, 4 * (i - 1)).Formula = "=" & sSOURCE & "A" & i & " + " & sSOURCE & "B" & i
    Next i

End Sub

There are some great answers mentioned here. Another approach you could take would be to use some free SDKs available online like Atooma, tranql and Neura, that can be integrated with your Android application (it takes less than 20 min to integrate). Along with giving you the accurate location of your user, it can also give you good insights about your user’s activities. Also, some of them consume less than 1% of your battery

You do not need to use an anonymous function with setTimeout. You can do something like this:

setTimeout(doSomething, 3000);

function doSomething() {
   //do whatever you want here
}

decimal pay  = 1.994444M;

Math.Round(pay , 2); 

The following captures stdout and stderr of the process in a single variable. It is Python 2 and 3 compatible:

from subprocess import check_output, CalledProcessError, STDOUT

command = ["ls", "-l"]
try:
    output = check_output(command, stderr=STDOUT).decode()
    success = True 
except CalledProcessError as e:
    output = e.output.decode()
    success = False

If your command is a string rather than an array, prefix this with:

import shlex
command = shlex.split(command)

Function

 CREATE FUNCTION [dbo].[fnSplit] ( @sep CHAR(1), @str VARCHAR(512) )
 RETURNS TABLE AS
 RETURN (
           WITH Pieces(pn, start, stop) AS (
           SELECT 1, 1, CHARINDEX(@sep, @str)
           UNION ALL
           SELECT pn + 1, stop + 1, CHARINDEX(@sep, @str, stop + 1)
           FROM Pieces
           WHERE stop > 0
      )

      SELECT
           pn AS Id,
           SUBSTRING(@str, start, CASE WHEN stop > 0 THEN stop - start ELSE 512 END) AS Data
      FROM
           Pieces
 )

Query

 DECLARE @FilterTable TABLE (Data VARCHAR(512))

 INSERT INTO @FilterTable (Data)
 SELECT DISTINCT S.Data
 FROM fnSplit(' ', 'word1 word2 word3') S -- Contains words

 SELECT DISTINCT
      T.*
 FROM
      MyTable T
      INNER JOIN @FilterTable F1 ON T.Column1 LIKE '%' + F1.Data + '%'
      LEFT JOIN @FilterTable F2 ON T.Column1 NOT LIKE '%' + F2.Data + '%'
 WHERE
      F2.Data IS NULL

The recommended approach is to use fill constructor to initialize a two-dimensional vector with a given default value :

std::vector<std::vector<int>> fog(M, std::vector<int>(N, default_value));

where, M and N are dimensions for your 2D vector.

Configuring a button (or any widget) in Tkinter is done by calling a configure method "config"

To change the size of a button called button1 you simple call

button1.config( height = WHATEVER, width = WHATEVER2 )

If you know what size you want at initialization these options can be added to the constructor.

button1 = Button(self, text = "Send", command = self.response1, height = 100, width = 100) 

Python string parsing walkthrough

Split a string on space, get a list, show its type, print it out:

el@apollo:~/foo$ python
>>> mystring = "What does the fox say?"

>>> mylist = mystring.split(" ")

>>> print type(mylist)
<type 'list'>

>>> print mylist
['What', 'does', 'the', 'fox', 'say?']

If you have two delimiters next to each other, empty string is assumed:

el@apollo:~/foo$ python
>>> mystring = "its  so   fluffy   im gonna    DIE!!!"

>>> print mystring.split(" ")
['its', '', 'so', '', '', 'fluffy', '', '', 'im', 'gonna', '', '', '', 'DIE!!!']

Split a string on underscore and grab the 5th item in the list:

el@apollo:~/foo$ python
>>> mystring = "Time_to_fire_up_Kowalski's_Nuclear_reactor."

>>> mystring.split("_")[4]
"Kowalski's"

Collapse multiple spaces into one

el@apollo:~/foo$ python
>>> mystring = 'collapse    these       spaces'

>>> mycollapsedstring = ' '.join(mystring.split())

>>> print mycollapsedstring.split(' ')
['collapse', 'these', 'spaces']

When you pass no parameter to Python's split method, the documentation states: "runs of consecutive whitespace are regarded as a single separator, and the result will contain no empty strings at the start or end if the string has leading or trailing whitespace".

Hold onto your hats boys, parse on a regular expression:

el@apollo:~/foo$ python
>>> mystring = 'zzzzzzabczzzzzzdefzzzzzzzzzghizzzzzzzzzzzz'
>>> import re
>>> mylist = re.split("[a-m]+", mystring)
>>> print mylist
['zzzzzz', 'zzzzzz', 'zzzzzzzzz', 'zzzzzzzzzzzz']

The regular expression "[a-m]+" means the lowercase letters a through m that occur one or more times are matched as a delimiter. re is a library to be imported.

Or if you want to chomp the items one at a time:

el@apollo:~/foo$ python
>>> mystring = "theres coffee in that nebula"

>>> mytuple = mystring.partition(" ")

>>> print type(mytuple)
<type 'tuple'>

>>> print mytuple
('theres', ' ', 'coffee in that nebula')

>>> print mytuple[0]
theres

>>> print mytuple[2]
coffee in that nebula

After some years have passed, you can do that now with ES6 Array.from (or spread syntax):

const navbar = Array.from(document.querySelectorAll('#navbar>ul>li'));_x000D_
console.log('Get first: ', navbar[0].textContent);_x000D_
_x000D_
// If you need to iterate once over all these nodes, you can use the callback function:_x000D_
console.log('Iterate with Array.from callback argument:');_x000D_
Array.from(document.querySelectorAll('#navbar>ul>li'),li => console.log(li.textContent))_x000D_
_x000D_
// ... or a for...of loop:_x000D_
console.log('Iterate with for...of:');_x000D_
for (const li of document.querySelectorAll('#navbar>ul>li')) {_x000D_
    console.log(li.textContent);_x000D_
}

.as-console-wrapper { max-height: 100% !important; top: 0; }

<div id="navbar">_x000D_
  <ul>_x000D_
    <li id="navbar-One">One</li>_x000D_
    <li id="navbar-Two">Two</li>_x000D_
    <li id="navbar-Three">Three</li>_x000D_
  </ul>_x000D_
</div>

make an example:

var body = document.body,
    btn = document.getElementById( 'id' );
body.addEventListener( 'click', function( event ) {
    console.log( event.currentTarget === body );
    console.log( event.target === btn );
}, false );

when you click 'btn', and 'true' and 'true' will be appeared!

The most convenient way according to me is:

(Val in X[:, col_num])

where Val is the value that you want to check for and X is the array. In your example, suppose you want to check if the value 8 exists in your the third column. Simply write

(8 in X[:, 2])

This will return True if 8 is there in the third column, else False.

Math.sqrt(Math.abs(variable))

Couldn't be more simple can it ?

For centos7 I required: sudo yum install mysql-devel gcc python-pip python-devel sudo pip install mysql-python

So, gcc and mysql-devel (rather than mysql) were important

grep -r -e string directory

-r is for recursive; -e is optional but its argument specifies the regex to search for. Interestingly, POSIX grep is not required to support -r (or -R), but I'm practically certain that System V grep did, so in practice they (almost) all do. Some versions of grep support -R as well as (or conceivably instead of) -r; AFAICT, it means the same thing.

DateTime.Now.ToShortDateString() will display only the date part

With the onclick parameter...

<a href='http://www.google.com' onclick='myJavaScriptFunction();'>mylink</a>

Not sure from what version, but I use 1.3.14 and you can just use:

window.location.href = '/employee/1';

No need to inject $location or $window in the controller and no need to get the current host address.

Indeed there is an API to search google programmatically. The API is called google custom search. For using this API, you will need an Google Developer API key and a cx key. A simple procedure for accessing google search from java program is explained in my blog.

Now dead, here is the Wayback Machine link.

You can apply the list as separate arguments:

print(*L)

and let print() take care of converting each element to a string. You can, as always, control the separator by setting the sep keyword argument:

>>> L = [1, 2, 3, 4, 5]
>>> print(*L)
1 2 3 4 5
>>> print(*L, sep=', ')
1, 2, 3, 4, 5
>>> print(*L, sep=' -> ')
1 -> 2 -> 3 -> 4 -> 5

Unless you need the joined string for something else, this is the easiest method. Otherwise, use str.join():

joined_string = ' '.join([str(v) for v in L])
print(joined_string)
# do other things with joined_string

Note that this requires manual conversion to strings for any non-string values in L!

Try

location ~ ^/(first/location|second/location)/ {
  ...
}

The ~ means to use a regular expression for the url. The ^ means to check from the first character. This will look for a / followed by either of the locations and then another /.

I have encountered this problem and finally solved it today, so I write down what I have learned and I hope it is helpful for someone who is new to Android's ViewPager and update as I do. I'm using FragmentStatePagerAdapter in API level 17 and currently have just 2 fragments. I think there must be something not correct, please correct me, thanks.

1. Serialized data has to be loaded into memory. This can be done using a CursorLoader/AsyncTask/Thread. Whether it's automatically loaded depends on your code. If you are using a CursorLoader, it's auto-loaded since there is a registered data observer.

2. After you call viewpager.setAdapter(pageradapter), the adapter's getCount() is constantly called to build fragments. So if data is being loaded, getCount() can return 0, thus you don't need to create dummy fragments for no data shown.

3. After the data is loaded, the adapter will not build fragments automatically since getCount() is still 0, so we can set the actually loaded data number to be returned by getCount(), then call the adapter's notifyDataSetChanged(). ViewPager begin to create fragments (just the first 2 fragments) by data in memory. It's done before notifyDataSetChanged() is returned. Then the ViewPager has the right fragments you need.

4. If the data in the database and memory are both updated (write through), or just data in memory is updated (write back), or only data in the database is updated. In the last two cases if data is not automatically loaded from the database to memory (as mentioned above). The ViewPager and pager adapter just deal with data in memory.

5. So when data in memory is updated, we just need to call the adapter's notifyDataSetChanged(). Since the fragment is already created, the adapter's onItemPosition() will be called before notifyDataSetChanged() returns. Nothing needs to be done in getItemPosition(). Then the data is updated.

To append after the pattern: (-i is for in place replace). line1 and line2 are the lines you want to append(or prepend)

sed -i '/pattern/a \
line1 \
line2' inputfile

Output:

#cat inputfile
 pattern
 line1 line2 

To prepend the lines before:

sed -i '/pattern/i \
line1 \
line2' inputfile

Output:

#cat inputfile
 line1 line2 
 pattern

$this->db->where('(a = 1 or a = 2)');

Building off @ted.strauss's answer, you can select SSH and MyIP from the drop down menu instead of navigating to a third party site.

Here is what I'm doing very easily: I modified my base.html file for my template and put that at the bottom:

{% if DJdata %}
    <script type="text/javascript">
        (function () {window.DJdata = {{DJdata|safe}};})();
    </script>
{% endif %}

then when I want to use a variable in the javascript files, I create a DJdata dictionary and I add it to the context by a json : context['DJdata'] = json.dumps(DJdata)

Hope it helps!

Using LIKE:

SELECT *
  FROM TABLE
 WHERE column LIKE '%cats%'  --case-insensitive

I know this is a little old but I wanted to add an updated answer with f-strings which were introduced in Python version 3.6:

msg['Subject'] = f'Auto Hella Restart Report {sys.argv[1]}'

In the first case you are declaring "int a" as a local variable(as declared inside a method) and local varible do not get default value.

But instance variable are given default value both for static and non-static.

Default value for instance variable:

int = 0

float,double = 0.0

reference variable = null

char = 0 (space character)

boolean = false

Solution using pagination with offset & limit:

public int collectionCount(String collection) {
        Integer page = 0;
        List<QueryDocumentSnapshot> snaps = new ArrayList<>();
        findDocsByPage(collection, page, snaps);
        return snaps.size();
    }

public void findDocsByPage(String collection, Integer page, 
                           List<QueryDocumentSnapshot> snaps) {
    try {
        Integer limit = 26000;
        FieldPath[] selectedFields = new FieldPath[] { FieldPath.of("id") };
        List<QueryDocumentSnapshot> snapshotPage;
        snapshotPage = fireStore()
                        .collection(collection)
                        .select(selectedFields)
                        .offset(page * limit)
                        .limit(limit)
                        .get().get().getDocuments();    
        if (snapshotPage.size() > 0) {
            snaps.addAll(snapshotPage);
            page++;
            findDocsByPage(collection, page, snaps);
        }
    } catch (InterruptedException | ExecutionException e) {
        e.printStackTrace();
    }
}

• findDocsPage it's a recursive method to find all pages of collection

• selectedFields for otimize query and get only id field instead full body of document

• limit max size of each query page

• page define inicial page for pagination

From the tests I did it worked well for collections with up to approximately 120k records!

may need to change the SCHEMA not only table

ALTER SCHEMA `<database name>`  DEFAULT CHARACTER SET utf8mb4  DEFAULT COLLATE utf8mb4_unicode_ci (as Rich said - utf8mb4);

Try this (copied-ish from Erik Garrison: https://stackoverflow.com/a/3071528/575530)

#include <sys/stat.h>

bool FileExists(char* filename) 
{
    struct stat fileInfo;
    return stat(filename, &fileInfo) == 0;
}

stat returns 0 if the file exists and -1 if not.

Add this little function and use it as so: $('div').scrollTo(500);

jQuery.fn.extend(
{
  scrollTo : function(speed, easing)
  {
    return this.each(function()
    {
      var targetOffset = $(this).offset().top;
      $('html,body').animate({scrollTop: targetOffset}, speed, easing);
    });
  }
});

I solved my problem like this

$('#startdatetime-from').datetimepicker({
language: 'en',
format: 'yyyy-MM-dd hh:mm',
defaultDate:new Date()
});

You can also relax your CSP for styles by adding style-src 'self' 'unsafe-inline';

"content_security_policy": "default-src 'self' style-src 'self' 'unsafe-inline';" 

This will allow you to keep using inline style in your extension.

Important note

As others have pointed out, this is not recommended, and you should put all your CSS in a dedicated file. See the OWASP explanation on why CSS can be a vector for attacks (kudos to @ KayakinKoder for the link).

If you need it with random unique values from 0...length range:

const randomRange = length => {
  const results = []
  const possibleValues = Array.from({ length }, (value, i) => i)

  for (let i = 0; i < length; i += 1) {
    const possibleValuesRange = length - (length - possibleValues.length)
    const randomNumber = Math.floor(Math.random() * possibleValuesRange)
    const normalizedRandomNumber = randomNumber !== possibleValuesRange ? randomNumber : possibleValuesRange

    const [nextNumber] = possibleValues.splice(normalizedRandomNumber, 1)

    results.push(nextNumber)
  }

  return results
}

randomRange(5) // [3, 0, 1, 4, 2]

I like to use this clean code to pass one value only:

startActivity(new Intent(context, YourActivity.class).putExtra("key","value"));

This make more simple to write and understandable code.

Here's what worked for me: right click the project-> source -> format After that just drag and drop the source folder into eclipse under the project and select link.

good luck!

Your debut and fin values are floating point values, not integers, because taille is a float.

Make those values integers instead:

item = plateau[int(debut):int(fin)]

Alternatively, make taille an integer:

taille = int(sqrt(len(plateau)))

I got this working by hard setting the attribute. And controlling the attribute applicability using the boolean value for the attribute.

Here is the code snippet:

<div contenteditable="{{ condition ? 'true' : 'false'}}"></div>

I hope this helps.

not equals. See here for a list of conditions

To complete the answer from Sotorios Delimanolis.

It's true that ResponseEntity gives you more flexibility but in most cases you won't need it and you'll end up with these ResponseEntity everywhere in your controller thus making it difficult to read and understand.

If you want to handle special cases like errors (Not Found, Conflict, etc.), you can add a HandlerExceptionResolver to your Spring configuration. So in your code, you just throw a specific exception (NotFoundException for instance) and decide what to do in your Handler (setting the HTTP status to 404), making the Controller code more clear.

The following should do it:

$("input[type='checkbox']").click(function() {
    var index = $(this).attr('name').substr(2);
    $('table tr').each(function() { 
        $('td:eq(' + index + ')',this).toggle();
    });
});

This is untested code, but the principle is that you choose the table cell in each row that corresponds to the chosen index extracted from the checkbox name. You could of course limit the selectors with a class or an ID.

$description = nl2br(stripcslashes($description));

The CSS :first-child selector allows you to target an element that is the first child element within its parent.

element:first-child { style_properties }
table:first-child { style_properties }

Primary keys always need to be unique, foreign keys need to allow non-unique values if the table is a one-to-many relationship. It is perfectly fine to use a foreign key as the primary key if the table is connected by a one-to-one relationship, not a one-to-many relationship. If you want the same user record to have the possibility of having more than 1 related profile record, go with a separate primary key, otherwise stick with what you have.

There are potential problems if you write your own recursive implementation or the iterative equivalent with stack. See this example:

    dic = {}
    dic["key1"] = {}
    dic["key1"]["key1.1"] = "value1"
    dic["key2"]  = {}
    dic["key2"]["key2.1"] = "value2"
    dic["key2"]["key2.2"] = dic["key1"]
    dic["key2"]["key2.3"] = dic

In the normal sense, nested dictionary will be a n-nary tree like data structure. But the definition doesn't exclude the possibility of a cross edge or even a back edge (thus no longer a tree). For instance, here key2.2 holds to the dictionary from key1, key2.3 points to the entire dictionary(back edge/cycle). When there is a back edge(cycle), the stack/recursion will run infinitely.

                          root<-------back edge
                        /      \           |
                     _key1   __key2__      |
                    /       /   \    \     |
               |->key1.1 key2.1 key2.2 key2.3
               |   /       |      |
               | value1  value2   |
               |                  | 
              cross edge----------|

If you print this dictionary with this implementation from Scharron

    def myprint(d):
      for k, v in d.items():
        if isinstance(v, dict):
          myprint(v)
        else:
          print "{0} : {1}".format(k, v)

You would see this error:

    RuntimeError: maximum recursion depth exceeded while calling a Python object

The same goes with the implementation from senderle.

Similarly, you get an infinite loop with this implementation from Fred Foo:

    def myprint(d):
        stack = list(d.items())
        while stack:
            k, v = stack.pop()
            if isinstance(v, dict):
                stack.extend(v.items())
            else:
                print("%s: %s" % (k, v))

However, Python actually detects cycles in nested dictionary:

    print dic
    {'key2': {'key2.1': 'value2', 'key2.3': {...}, 
       'key2.2': {'key1.1': 'value1'}}, 'key1': {'key1.1': 'value1'}}

"{...}" is where a cycle is detected.

As requested by Moondra this is a way to avoid cycles (DFS):

def myprint(d): 
    stack = list(d.items()) 
    visited = set() 
    while stack: 
        k, v = stack.pop() 
        if isinstance(v, dict): 
            if k not in visited: 
                stack.extend(v.items()) 
        else: 
            print("%s: %s" % (k, v)) 
        visited.add(k)

BufferedWriter is more efficient if you

• have multiple writes between flush/close
• the writes are small compared with the buffer size.

In your example, you have only one write, so the BufferedWriter just add overhead you don't need.

so does that mean the first example writes the characters one by one and the second first buffers it to the memory and writes it once

In both cases, the string is written at once.

If you use just FileWriter your write(String) calls

 public void write(String str, int off, int len) 
        // some code
        str.getChars(off, (off + len), cbuf, 0);
        write(cbuf, 0, len);
 }

This makes one system call, per call to write(String).

Where BufferedWriter improves efficiency is in multiple small writes.

for(int i = 0; i < 100; i++) {
    writer.write("foorbar");
    writer.write(NEW_LINE);
}
writer.close();

Without a BufferedWriter this could make 200 (2 * 100) system calls and writes to disk which is inefficient. With a BufferedWriter, these can all be buffered together and as the default buffer size is 8192 characters this become just 1 system call to write.

By default, there is not any proper answer to disable saving a password in your browser. But luckily there is a way around and it works in almost all the browsers.

To achieve this, add a dummy input just before the actual input with autocomplete="off" and some custom styling to hide it and providing tabIndex.

Some browsers' (Chrome) autocomplete will fill in the first password input it finds, and the input before that, so with this trick it will only fill in an invisible input that doesn't matter.

          <div className="password-input">
            <input
              type="password"
              id="prevent_autofill"
              autoComplete="off"
              style={{
                opacity: '0',
                position: 'absolute',
                height: '0',
                width: '0',
                padding: '0',
                margin: '0'
              }}
              tabIndex="-2"
            />
            <input
              type="password"
              autoComplete="off"

I'm a newbie to pandas. But this is how I understand axis in pandas:

Axis Constant Varying Direction

0 Column Row Downwards |

1 Row Column Towards Right -->

So to compute mean of a column, that particular column should be constant but the rows under that can change (varying) so it is axis=0.

Similarly, to compute mean of a row, that particular row is constant but it can traverse through different columns (varying), axis=1.

The typical use is

void* ret = NULL;
pthread_t tid = something; /// change it suitably
if (pthread_join (tid, &ret)) 
   handle_error();
// do something with the return value ret

This can also occur if you are using a persisted model cache which is out of date for one reason or another. If your context has been cached to an EDMX file on a file system (via DbConfiguration.SetModelStore) then OnModelCreating will never be called as the cached version will be used. As a result if an entity is missing from your cached store then you will get the above error even though the connection string is correct, the table exists in the database and the entity is set up correctly in your DbContext.

In my case I was using more than two variables, and this worked for me better:

cor(x = as.matrix(tbl), method = "pearson", use = "pairwise.complete.obs")

However:

If use has the value "pairwise.complete.obs" then the correlation or covariance between each pair of variables is computed using all complete pairs of observations on those variables. This can result in covariance or correlation matrices which are not positive semi-definite, as well as NA entries if there are no complete pairs for that pair of variables.

UPDATE (Nov 24th, 2015):

This answer is originally posted in the year 2010 (SIX years back.) so please take note of these insightful comments:

• Shauna -

Update for Googlers - Looks like ECMA6 adds this function. The MDN article also shows a polyfill. https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/endsWith

• T.J. Crowder -

Creating substrings isn't expensive on modern browsers; it may well have been in 2010 when this answer was posted. These days, the simple this.substr(-suffix.length) === suffix approach is fastest on Chrome, the same on IE11 as indexOf, and only 4% slower (fergetaboutit territory) on Firefox: jsperf.com/endswith-stackoverflow/14 And faster across the board when the result is false: jsperf.com/endswith-stackoverflow-when-false Of course, with ES6 adding endsWith, the point is moot. :-)

ORIGINAL ANSWER:

I know this is a year old question... but I need this too and I need it to work cross-browser so... combining everyone's answer and comments and simplifying it a bit:

String.prototype.endsWith = function(suffix) {
    return this.indexOf(suffix, this.length - suffix.length) !== -1;
};

• Doesn't create a substring
• Uses native indexOf function for fastest results
• Skip unnecessary comparisons using the second parameter of indexOf to skip ahead
• Works in Internet Explorer
• NO Regex complications

Also, if you don't like stuffing things in native data structure's prototypes, here's a standalone version:

function endsWith(str, suffix) {
    return str.indexOf(suffix, str.length - suffix.length) !== -1;
}

EDIT: As noted by @hamish in the comments, if you want to err on the safe side and check if an implementation has already been provided, you can just adds a typeof check like so:

if (typeof String.prototype.endsWith !== 'function') {
    String.prototype.endsWith = function(suffix) {
        return this.indexOf(suffix, this.length - suffix.length) !== -1;
    };
}

We can collect the form params submitted using POST with using serialize concept.

Try this:

$('form').serialize(); 

Just enclose it alert, it displays all the parameters including hidden.

aparse() {
while [[ $# > 0 ]] ; do
  case "$1" in
    --arg1)
      varg1=${2}
      shift
      ;;
    --arg2)
      varg2=true
      ;;
  esac
  shift
done
}

aparse "$@"

Generator expressions are also possible:

target_link_libraries(
    target_name
    PUBLIC
        libA
        $<$<PLATFORM_ID:Windows>:wsock32>
    PRIVATE
        $<$<PLATFORM_ID:Linux>:libB>
        libC
)

This will link libA, wsock32 & libC on Windows and link libA, libB & libC on Linux

CMake Generator Expressions

Because in either case the increment is done after the body of the loop and thus doesn't affect any of the calculations of the loop. If the compiler is stupid, it might be slightly less efficient to use post-increment (because normally it needs to keep a copy of the pre value for later use), but I would expect any differences to be optimized away in this case.

It might be handy to think of how the for loop is implemented, essentially translated into a set of assignments, tests, and branch instructions. In pseudo-code the pre-increment would look like:

      set i = 0
test: if i >= 5 goto done
      call printf,"%d",i
      set i = i + 1
      goto test
done: nop

Post-increment would have at least another step, but it would be trivial to optimize away

      set i = 0
test: if i >= 5 goto done
      call printf,"%d",i
      set j = i   // store value of i for later increment
      set i = j + 1  // oops, we're incrementing right-away
      goto test
done: nop

I just want to add my solution:

I use german umlauts like ö, ü, ä and got the same error.
@Jarek Zmudzinski just told you how it works, but here is mine:

Add this code to the top of your Controller: # encoding: UTF-8
(for example to use flash message with umlauts)

example of my Controller:

# encoding: UTF-8
class UserController < ApplicationController

Now you can use ö, ä ,ü, ß, "", etc.

Not possible without iterating to build a new list. You can wrap the list in a container that implements IList.

You can use LINQ to get a lazy evaluated version of IEnumerable<string> from an object list like this:

var stringList = myList.OfType<string>();

Just adding one point that was not mentioned in mmyers' answer.

If I know I want the first item, I can use set.iterator().next(), but otherwise it seems I have to cast to an Array to retrieve an item at a specific index?

What are the appropriate ways of retrieving data from a set? (other than using an iterator)

You should also familiarise yourself with the SortedSet interface (whose most common implementation is TreeSet).

A SortedSet is a Set (i.e. elements are unique) that is kept ordered by the natural ordering of the elements or using some Comparator. You can easily access the first and last items using first() and last() methods. A SortedSet comes in handy every once in a while, when you need to keep your collection both duplicate-free and ordered in a certain way.

Edit: If you need a Set whose elements are kept in insertion-order (much like a List), take a look at LinkedHashSet.

A list is considered to be False if it has no elements, so you can do something like this:

{% if mylist %}
    <p>I have a list!</p>
{% else %}
    <p>I don't have a list!</p>
{% endif %}

It's also possible the problem is with a parameter or return type of the method that's reported missing, and the "missing" method per se is fine.

That's what was happening in my case, and the misleading message made it take much longer to figure out the issue. It turns out the assembly for a parameter's type had an older version in the GAC, but the older version actually had a higher version number due to a change in version numbering schemes used. Removing that older/higher version from the GAC fixed the problem.

Use:

enter code var moment = require('moment')
var startDate = moment('2013-5-11 8:73:18', 'YYYY-M-DD HH:mm:ss')

Moment.js works very well. You can read more about it here.

As other answers in this thread have pointed out, to resolve this error you need to carefully inspect the code, to understand where the file is getting locked.

In my case, I was sending out the file as an email attachment before performing the move operation.

So the file got locked for couple of seconds until SMTP client finished sending the email.

The solution I adopted was to move the file first, and then send the email. This solved the problem for me.

Another possible solution, as pointed out earlier by Hudson, would've been to dispose the object after use.

public static SendEmail()
{
           MailMessage mMailMessage = new MailMessage();
           //setup other email stuff

            if (File.Exists(attachmentPath))
            {
                Attachment attachment = new Attachment(attachmentPath);
                mMailMessage.Attachments.Add(attachment);
                attachment.Dispose(); //disposing the Attachment object
            }
} 

You can do it using the foreach loop

DataTable dr_art_line_2 = ds.Tables["QuantityInIssueUnit"];

  foreach(DataRow row in dr_art_line_2.Rows)
  {
     QuantityInIssueUnit_value = Convert.ToInt32(row["columnname"]);
  }

I have to add in httpd.conf this line (Windows):

LoadFile "C:/Program Files (x86)/PostgreSQL/8.3/bin/libpq.dll"

From time to time I present MR concepts to people. I find processing tasks familiar to people and then map them to the MR paradigm.

Usually I take two things:

1. Group By / Aggregations. Here the advantage of the shuffling stage is clear. An explanation that shuffling is also distributed sort + an explanation of distributed sort algorithm also helps.

2. Join of two tables. People working with DB are familiar with the concept and its scalability problem. Show how it can be done in MR.

$date= new DateTime($row['your_date']) ;  
echo $date->format('Y-m-d');

When I had this problem was beacuse my directory had non ASCII characteres. Try changing it

Whilst you certainly can use MySQL's IF() control flow function as demonstrated by dbemerlin's answer, I suspect it might be a little clearer to the reader (i.e. yourself, and any future developers who might pick up your code in the future) to use a CASE expression instead:

UPDATE Table
SET    A = CASE
         WHEN A > 0 AND A < 1 THEN 1
         WHEN A > 1 AND A < 2 THEN 2
         ELSE A
       END
WHERE  A IS NOT NULL

Of course, in this specific example it's a little wasteful to set A to itself in the ELSE clause—better entirely to filter such conditions from the UPDATE, via the WHERE clause:

UPDATE Table
SET    A = CASE
         WHEN A > 0 AND A < 1 THEN 1
         WHEN A > 1 AND A < 2 THEN 2
       END
WHERE  (A > 0 AND A < 1) OR (A > 1 AND A < 2)

(The inequalities entail A IS NOT NULL).

Or, if you want the intervals to be closed rather than open (note that this would set values of 0 to 1—if that is undesirable, one could explicitly filter such cases in the WHERE clause, or else add a higher precedence WHEN condition):

UPDATE Table
SET    A = CASE
         WHEN A BETWEEN 0 AND 1 THEN 1
         WHEN A BETWEEN 1 AND 2 THEN 2
       END
WHERE  A BETWEEN 0 AND 2

Though, as dbmerlin also pointed out, for this specific situation you could consider using CEIL() instead:

UPDATE Table SET A = CEIL(A) WHERE A BETWEEN 0 AND 2

I have done exactly this with an ICustomTypeDescriptor interface and a Dictionary.

Implementing ICustomTypeDescriptor for dynamic properties:

I have recently had a requirement to bind a grid view to a record object that could have any number of properties that can be added and removed at runtime. This was to allow a user to add a new column to a result set to enter an additional set of data.

This can be achieved by having each data 'row' as a dictionary with the key being the property name and the value being a string or a class that can store the value of the property for the specified row. Of course having a List of Dictionary objects will not be able to be bound to a grid. This is where the ICustomTypeDescriptor comes in.

By creating a wrapper class for the Dictionary and making it adhere to the ICustomTypeDescriptor interface the behaviour for returning properties for an object can be overridden.

Take a look at the implementation of the data 'row' class below:

/// <summary>
/// Class to manage test result row data functions
/// </summary>
public class TestResultRowWrapper : Dictionary<string, TestResultValue>, ICustomTypeDescriptor

        //Add property descriptors for each entry in the dictionary
        foreach (string key in this.Keys)
        {
            properties.Add(new TestResultPropertyDescriptor(key));
        }

        //Get properties also belonging to this class also
        PropertyDescriptorCollection pdc = TypeDescriptor.GetProperties(this.GetType(), attributes);

        foreach (PropertyDescriptor oPropertyDescriptor in pdc)
        {
            properties.Add(oPropertyDescriptor);
        }

        return new PropertyDescriptorCollection(properties.ToArray());
    }

Note: In the GetProperties method I Could Cache the PropertyDescriptors once read for performance but as I'm adding and removing columns at runtime I always want them rebuilt

You will also notice in the GetProperties method that the Property Descriptors added for the dictionary entries are of type TestResultPropertyDescriptor. This is a custom Property Descriptor class that manages how properties are set and retrieved. Take a look at the implementation below:

The main properties to look at on this class are GetValue and SetValue. Here you can see the component being casted as a dictionary and the value of the key inside it being Set or retrieved. Its important that the dictionary in this class is the same type in the Row wrapper class otherwise the cast will fail. When the descriptor is created the key (property name) is passed in and is used to query the dictionary to get the correct value.

Taken from my blog at:

hash_items = {:item => 1}
puts hash_items 
#hash_items will give you {:item => 1}

hash_items.merge!({:item => 2})
puts hash_items 
#hash_items will give you {:item => 1, :item => 2}

hash_items.merge({:item => 2})
puts hash_items 
#hash_items will give you {:item => 1, :item => 2}, but the original variable will be the same old one.

Here is example code you could run to make such test:

var f = 10000000;
var p = new int[f];

for(int i = 0; i < f; ++i)
{
    p[i] = i % 2;
}

var time = DateTime.Now;
p.Sum();
Console.WriteLine(DateTime.Now - time);

int x = 0;
time = DateTime.Now;
foreach(var item in p){
   x += item;
}
Console.WriteLine(DateTime.Now - time);

x = 0;
time = DateTime.Now;
for(int i = 0, j = f; i < j; ++i){
   x += p[i];
}
Console.WriteLine(DateTime.Now - time);

The same example for complex object is:

void Main()
{
    var f = 10000000;
    var p = new Test[f];

    for(int i = 0; i < f; ++i)
    {
        p[i] = new Test();
        p[i].Property = i % 2;
    }

    var time = DateTime.Now;
    p.Sum(k => k.Property);
    Console.WriteLine(DateTime.Now - time);

    int x = 0;
    time = DateTime.Now;
    foreach(var item in p){
        x += item.Property;
    }
    Console.WriteLine(DateTime.Now - time);

    x = 0;
    time = DateTime.Now;
    for(int i = 0, j = f; i < j; ++i){
        x += p[i].Property;
    }
    Console.WriteLine(DateTime.Now - time);
}

}

My results with compiler optimizations off are:

00:00:00.0250180 : Foreach()
00:00:00.0430272 : For(...)

and for second test are:

00:00:00.0650430 : Foreach()
00:00:00.0690510 : For()

it looks like LINQ is generally slower than foreach(...) but what is weird for me is that foreach(...) appears to be faster than for loop.

I would like to add this config.allowedContent = true; needs to be added to the ckeditor.config.js file not the config.js, config.js did nothing for me but adding it to the top area of ckeditor.config.js kept my div classes

This worked for me, even within a div:

      div.cntrblk tr:hover td {
        line-height: 150%;
        background-color: rgb(255,0,0);
        font-weight: bold;
        font-size: 150%;
        border: 0;
      }

It selected the entire row, but I'd like it to not do the header, haven't looked at that yet. It also partially fixed the fonts that wouldn't scale-up with the hover??? Apparently you to have apply settings to the cell not the row, but select all the component cells with the tr:hover. On to tracking down the in-consistent font scaling problem. Sweet that CSS will do this.

The dat file has some lines of extra information before the actual data. Skip them with the skip argument:

read.table("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat", 
           header=TRUE, skip=3)

An easy way to check this if you are unfamiliar with the dataset is to first use readLines to check a few lines, as below:

readLines("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat", 
          n=10)
# [1] "Ozone data from CZ03 2009"   "Local time: GMT + 0"        
# [3] ""                            "Date        Hour      Value"
# [5] "01.01.2009 00:00       34.3" "01.01.2009 01:00       31.9"
# [7] "01.01.2009 02:00       29.9" "01.01.2009 03:00       28.5"
# [9] "01.01.2009 04:00       32.9" "01.01.2009 05:00       20.5"

Here, we can see that the actual data starts at [4], so we know to skip the first three lines.

Update

If you really only wanted the Value column, you could do that by:

as.vector(
    read.table("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat",
               header=TRUE, skip=3)$Value)

Again, readLines is useful for helping us figure out the actual name of the columns we will be importing.

But I don't see much advantage to doing that over reading the whole dataset in and extracting later.

I think there's an even easier way now. This enables basic caching for all $http requests (which $resource inherits):

 var app = angular.module('myApp',[])
      .config(['$httpProvider', function ($httpProvider) {
            // enable http caching
           $httpProvider.defaults.cache = true;
      }])

I'm not sure whats going wrong with your set up. Maybe the server is not setting the headers properly. Not sure. As a long shot, you can try this

$.ajax({
    url : url,
    dataType : 'json'
})
.done(function(data, statusText, resObject) {
   var jsonData = resObject.responseJSON
})

Python 3 standard library one-liner:

load(urlopen(url))

# imports (place these above the code before running it)
from json import load
from urllib.request import urlopen
url = 'https://jsonplaceholder.typicode.com/todos/1'

You can try,

 <?php

     if (isset($_POST["mail"])) {
            echo "Yes, mail is set";    
        }else{  
            echo "N0, mail is not set";
        }
  ?>

System.Windows.Forms.Application.Exit() - Informs all message pumps that they must terminate, and then closes all application windows after the messages have been processed. This method stops all running message loops on all threads and closes all windows of the application. This method does not force the application to exit. The Exit() method is typically called from within a message loop, and forces Run() to return. To exit a message loop for the current thread only, call ExitThread(). This is the call to use if you are running a Windows Forms application. As a general guideline, use this call if you have called System.Windows.Forms.Application.Run().

System.Environment.Exit(exitCode) - Terminates this process and gives the underlying operating system the specified exit code. This call requires that you have SecurityPermissionFlag.UnmanagedCode permissions. If you do not, a SecurityException error occurs. This is the call to use if you are running a console application.

I hope it is best to use Application.Exit

Maybe: UPDATE test SET data = '"my-other-name"'::json WHERE id = 1;

It worked with my case, where data is a json type

I converted the pandas dataframe to list and then used the basic list.index(). Something like this:

dd = list(zone[0]) #Where zone[0] is some specific column of the table
idx = dd.index(filename[i])

You have you index value as idx.

Sorry to resurrect an old question, but I thought I might contribute a couple of very basic examples and for-dummies explanations. None of the other answers posted thusfar illustrate syntax like the MDN guide's first example, which is about as basic as one can get.

Getter:

var settings = {
    firstname: 'John',
    lastname: 'Smith',
    get fullname() { return this.firstname + ' ' + this.lastname; }
};

console.log(settings.fullname);

... will log John Smith, of course. A getter behaves like a variable object property, but offers the flexibility of a function to calculate its returned value on the fly. It's basically a fancy way to create a function that doesn't require () when calling.

Setter:

var address = {
    set raw(what) {
        var loc = what.split(/\s*;\s*/),
        area = loc[1].split(/,?\s+(\w{2})\s+(?=\d{5})/);

        this.street = loc[0];
        this.city = area[0];
        this.state = area[1];
        this.zip = area[2];
    }
};

address.raw = '123 Lexington Ave; New York NY  10001';
console.log(address.city);

... will log New York to the console. Like getters, setters are called with the same syntax as setting an object property's value, but are yet another fancy way to call a function without ().

See this jsfiddle for a more thorough, perhaps more practical example. Passing values into the object's setter triggers the creation or population of other object items. Specifically, in the jsfiddle example, passing an array of numbers prompts the setter to calculate mean, median, mode, and range; then sets object properties for each result.

LocalDate maxDate = dates.stream()
                            .max( Comparator.comparing( LocalDate::toEpochDay ) )
                            .get();

LocalDate minDate = dates.stream()
                            .min( Comparator.comparing( LocalDate::toEpochDay ) )
                            .get();

This is a lot simpler with .slideToggle():

jQuery('.class1 a').click( function() {
  $(this).next('.class2').slideToggle();
});

EDIT: made it .next instead of .siblings

Embedded environment, sometime, there is no MMU, less memory, less storage space. In C programming level, almost same, cross compiler do their job.

Here are the steps to pull a specific or any branch,

1.clone the master(you need to provide username and password)

       git clone <url>

2. the above command will clone the repository and you will be master branch now

       git checkout <branch which is present in the remote repository(origin)>

3. The above command will checkout to the branch you want to pull and will be set to automatically track that branch

4.If for some reason it does not work like that, after checking out to that branch in your local system, just run the below command

       git pull origin <branch>

Not sure if this is relevant to your question but it might be relevant to someone else in the future: I had a similar error. Turned out that the df was empty (had zero rows) and that is what was causing the error in my command.

The only difference between files that causing the issue is the 8th byte of file

CA FE BA BE 00 00 00 33 - Java 7

vs.

CA FE BA BE 00 00 00 32 - Java 6

Setting -XX:-UseSplitVerifier resolves the issue. However, the cause of this issue is https://bugs.eclipse.org/bugs/show_bug.cgi?id=339388

There is a Select2 plugin allowing to set a lot of cool stuff along with placeholder. It is a jQuery replacement for select boxes. Here is an official site https://select2.github.io/examples.html

The thing is - if you want to disable fancy search option, please use the following option set.

data-plugin-options='
{ 
    "placeholder": "Select status",
    "allowClear": true, 
    "minimumResultsForSearch": -1
}

Especially I like the allowClear option.

Thank you.

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

set nocount on

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

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

declare @PersonID int
set @PersonID = 1

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

drop table Timesheet_Hours

On the command line, \r will move the cursor back to the beginning of the current line. To see the difference you must run your code from a command prompt. Eclipse's console show similar output for both the expression. For complete list of escape sequences, click here https://docs.oracle.com/javase/specs/jls/se8/html/jls-3.html#jls-3.10.6

I have done this way:

Set Color on Text by passing String and color:

private String getColoredSpanned(String text, String color) {
    String input = "<font color=" + color + ">" + text + "</font>";
    return input;
}

Set text on TextView / Button / EditText etc by calling below code:

TextView:

TextView txtView = (TextView)findViewById(R.id.txtView);

Get Colored String:

String name = getColoredSpanned("Hiren", "#800000");
String surName = getColoredSpanned("Patel","#000080");

Set Text on TextView of two strings with different colors:

txtView.setText(Html.fromHtml(name+" "+surName));

Done

It sounds like you're looking for applicationHost.config, which is located in C:\Windows\System32\inetsrv\config.

Yes, it's an XML file, and yes, editing the file by hand will affect the IIS config after a restart. You can think of IIS Manager as a GUI front-end for editing applicationHost.config and web.config.

very old question, i know. but with the new f-strings (starting from python 3.6) there are fresh options. so here for completeness:

from datetime import datetime

dt = datetime.now()

# str.format
strg = '{:%B %d, %Y}'.format(dt)
print(strg)  # July 22, 2017

# datetime.strftime
strg = dt.strftime('%B %d, %Y')
print(strg)  # July 22, 2017

# f-strings in python >= 3.6
strg = f'{dt:%B %d, %Y}'
print(strg)  # July 22, 2017

strftime() and strptime() Behavior explains what the format specifiers mean.

If you are using jQuery you can easily fetch the data attributes by

$(this).data("id") or $(event.target).data("id")

There is no portable way to read raw characters from a Java console.

Some platform-dependent workarounds have been presented above. But to be really portable, you'd have to abandon console mode and use a windowing mode, e.g. AWT or Swing.

This is just torazaburo's answer, updated to use a MouseEvent object.

function click(x, y)
{
    var ev = new MouseEvent('click', {
        'view': window,
        'bubbles': true,
        'cancelable': true,
        'screenX': x,
        'screenY': y
    });

    var el = document.elementFromPoint(x, y);

    el.dispatchEvent(ev);
}

Thought I would chip in here with when I have found ON to be more useful than USING. It is when OUTER joins are introduced into queries.

ON benefits from allowing the results set of the table that a query is OUTER joining onto to be restricted while maintaining the OUTER join. Attempting to restrict the results set through specifying a WHERE clause will, effectively, change the OUTER join into an INNER join.

Granted this may be a relative corner case. Worth putting out there though.....

For example:

CREATE TABLE country (
   countryId int(10) unsigned NOT NULL PRIMARY KEY AUTO_INCREMENT,
   country varchar(50) not null,
  UNIQUE KEY countryUIdx1 (country)
) ENGINE=InnoDB;

insert into country(country) values ("France");
insert into country(country) values ("China");
insert into country(country) values ("USA");
insert into country(country) values ("Italy");
insert into country(country) values ("UK");
insert into country(country) values ("Monaco");


CREATE TABLE city (
  cityId int(10) unsigned NOT NULL PRIMARY KEY AUTO_INCREMENT,
  countryId int(10) unsigned not null,
  city varchar(50) not null,
  hasAirport boolean not null default true,
  UNIQUE KEY cityUIdx1 (countryId,city),
  CONSTRAINT city_country_fk1 FOREIGN KEY (countryId) REFERENCES country (countryId)
) ENGINE=InnoDB;


insert into city (countryId,city,hasAirport) values (1,"Paris",true);
insert into city (countryId,city,hasAirport) values (2,"Bejing",true);
insert into city (countryId,city,hasAirport) values (3,"New York",true);
insert into city (countryId,city,hasAirport) values (4,"Napoli",true);
insert into city (countryId,city,hasAirport) values (5,"Manchester",true);
insert into city (countryId,city,hasAirport) values (5,"Birmingham",false);
insert into city (countryId,city,hasAirport) values (3,"Cincinatti",false);
insert into city (countryId,city,hasAirport) values (6,"Monaco",false);

-- Gah. Left outer join is now effectively an inner join 
-- because of the where predicate
select *
from country left join city using (countryId)
where hasAirport
; 

-- Hooray! I can see Monaco again thanks to 
-- moving my predicate into the ON
select *
from country co left join city ci on (co.countryId=ci.countryId and ci.hasAirport)
; 

Double pipe stands for logical "OR". This is not really the case when the "parameter not set", since strictly in the javascript if you have code like this:

function foo(par) {
}

Then calls

foo()
foo("")
foo(null)
foo(undefined)
foo(0)

are not equivalent.

Double pipe (||) will cast the first argument to boolean and if resulting boolean is true - do the assignment otherwise it will assign the right part.

This matters if you check for unset parameter.

Let's say, we have a function setSalary that has one optional parameter. If user does not supply the parameter then the default value of 10 should be used.

if you do the check like this:

function setSalary(dollars) {
    salary = dollars || 10
}

This will give unexpected result on call like

setSalary(0) 

It will still set the 10 following the flow described above.

You could do this:

String json = new ObjectMapper().writeValueAsString(yourObjectHere);

I am posting the following because it is a very simple and clear way to mimic (at least to some extent) the behavior of a two-dimensional array in Bash. It uses a here-file (see the Bash manual) and read (a Bash builtin command):

## Store the "two-dimensional data" in a file ($$ is just the process ID of the shell, to make sure the filename is unique)
cat > physicists.$$ <<EOF
Wolfgang Pauli 1900
Werner Heisenberg 1901
Albert Einstein 1879
Niels Bohr 1885
EOF
nbPhysicists=$(wc -l physicists.$$ | cut -sf 1 -d ' ')     # Number of lines of the here-file specifying the physicists.

## Extract the needed data
declare -a person     # Create an indexed array (necessary for the read command).                                                                                 
while read -ra person; do
    firstName=${person[0]}
    familyName=${person[1]}
    birthYear=${person[2]}
    echo "Physicist ${firstName} ${familyName} was born in ${birthYear}"
    # Do whatever you need with data
done < physicists.$$

## Remove the temporary file
rm physicists.$$

Output: Physicist Wolfgang Pauli was born in 1900 Physicist Werner Heisenberg was born in 1901 Physicist Albert Einstein was born in 1879 Physicist Niels Bohr was born in 1885

The way it works:

• The lines in the temporary file created play the role of one-dimensional vectors, where the blank spaces (or whatever separation character you choose; see the description of the read command in the Bash manual) separate the elements of these vectors.
• Then, using the read command with its -a option, we loop over each line of the file (until we reach end of file). For each line, we can assign the desired fields (= words) to an array, which we declared just before the loop. The -r option to the read command prevents backslashes from acting as escape characters, in case we typed backslashes in the here-document physicists.$$.

In conclusion a file is created as a 2D-array, and its elements are extracted using a loop over each line, and using the ability of the read command to assign words to the elements of an (indexed) array.

Slight improvement:

In the above code, the file physicists.$$ is given as input to the while loop, so that it is in fact passed to the read command. However, I found that this causes problems when I have another command asking for input inside the while loop. For example, the select command waits for standard input, and if placed inside the while loop, it will take input from physicists.$$, instead of prompting in the command-line for user input. To correct this, I use the -u option of read, which allows to read from a file descriptor. We only have to create a file descriptor (with the exec command) corresponding to physicists.$$ and to give it to the -u option of read, as in the following code:

## Store the "two-dimensional data" in a file ($$ is just the process ID of the shell, to make sure the filename is unique)
cat > physicists.$$ <<EOF
Wolfgang Pauli 1900
Werner Heisenberg 1901
Albert Einstein 1879
Niels Bohr 1885
EOF
nbPhysicists=$(wc -l physicists.$$ | cut -sf 1 -d ' ')     # Number of lines of the here-file specifying the physicists.
exec {id_file}<./physicists.$$     # Create a file descriptor stored in 'id_file'.

## Extract the needed data
declare -a person     # Create an indexed array (necessary for the read command).                                                                                 
while read -ra person -u "${id_file}"; do
firstName=${person[0]}
familyName=${person[1]}
birthYear=${person[2]}
echo "Physicist ${firstName} ${familyName} was born in ${birthYear}"
# Do whatever you need with data
done

## Close the file descriptor
exec {id_file}<&-
## Remove the temporary file
rm physicists.$$

Notice that the file descriptor is closed at the end.

Well, if you installed MySql Server e.g. Version 5.5. which has it's folder located in:

C:\Program Files\MySQL\MySQL Server 5.5\bin

The best way would be to include it in your paths.

• First run sysdm.cpl applet from run i.e. WinKey + R

• Navigate to Advanced -> Environment Variables

• Select PATH and Click Edit.

• Scroll to the end of the text, and add ";C:\Program Files\MySQL\MySQL Server 5.5\bin" without quotes (Notice the semicolon starting the text, this should only be added if it's not already there),

Now you can just call:

start /b /wait mysql -u root -p

via command prompt.

To clear the screen now, you can just exit in mysql & call cls

Kinda trickish hack but does the job.

If you're using WAMP or other tool, it's even easier!

Open command prompt and type:

C:\wamp\mysql\bin\mysql -u root -p

Enter as normal, then whenever you want to clear screen, do:

exit or quit

And then clear using DOS:

cls

You can easily re-enter by pressing up twice to get your mysql call command

Undoubtly this can be simplified but the results match your expectations.

The gist of this is to

• Calculate the maximum price in a seperate CTE for each t2ID
• Calculate the total price in a seperate CTE for each t2ID
• Combine the results of both CTE's

SQL Statement

;WITH MaxPrice AS ( 
    SELECT  t2ID
            , t1ID
    FROM    (       
                SELECT  t2.ID AS t2ID
                        , t1.ID AS t1ID
                        , rn = ROW_NUMBER() OVER (PARTITION BY t2.ID ORDER BY t1.Price DESC)
                FROM    @t1 t1
                        INNER JOIN @relation r ON r.t1ID = t1.ID        
                        INNER JOIN @t2 t2 ON t2.ID = r.t2ID
            ) maxt1
    WHERE   maxt1.rn = 1                            
)
, SumPrice AS (
    SELECT  t2ID = t2.ID
            , Price = SUM(Price)
    FROM    @t1 t1
            INNER JOIN @relation r ON r.t1ID = t1.ID
            INNER JOIN @t2 t2 ON t2.ID = r.t2ID
    GROUP BY
            t2.ID           
)           
SELECT  t2.ID
        , t2.Name
        , t2.Orders
        , mp.t1ID
        , t1.ID
        , t1.Name
        , sp.Price
FROM    @t2 t2
        INNER JOIN MaxPrice mp ON mp.t2ID = t2.ID
        INNER JOIN SumPrice sp ON sp.t2ID = t2.ID
        INNER JOIN @t1 t1 ON t1.ID = mp.t1ID

If you're using MySQL and want the database itself to perform the conversion, use this:

DATE_FORMAT(date,format)

If you prefer to format using Java, use this:

java.text.SimpleDateFormat

SimpleDateFormat dateFormat = new SimpleDateFormat("M/dd/yyyy");
dateFormat.format( new Date() );

Here are my two solutions.

Short answer:

Instead of creating a layer-list, I separated it into two files. One for ProgressBar and one for its background.

This is the ProgressDrawable file (@drawable folder): circular_progress_bar.xml

<?xml version="1.0" encoding="utf-8"?>
<rotate xmlns:android="http://schemas.android.com/apk/res/android"
    android:fromDegrees="270"
    android:toDegrees="270">
    <shape
        android:innerRadiusRatio="2.5"
        android:shape="ring"
        android:thickness="1dp"
        android:useLevel="true"><!-- this line fixes the issue for lollipop api 21 -->

        <gradient
            android:angle="0"
            android:endColor="#007DD6"
            android:startColor="#007DD6"
            android:type="sweep"
            android:useLevel="false" />
    </shape>
</rotate>

And this is for its background(@drawable folder): circle_shape.xml

<?xml version="1.0" encoding="utf-8"?>
<shape
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="ring"
    android:innerRadiusRatio="2.5"
    android:thickness="1dp"
    android:useLevel="false">

    <solid android:color="#CCC" />

</shape>

And at the end, inside the layout that you're working:

<ProgressBar
        android:id="@+id/progressBar"
        android:layout_width="200dp"
        android:layout_height="200dp"
        android:indeterminate="false"
        android:progressDrawable="@drawable/circular_progress_bar"
        android:background="@drawable/circle_shape"
        style="?android:attr/progressBarStyleHorizontal"
        android:max="100"
        android:progress="65" />

Here's the result:

Long Answer:

Use a custom view which inherits the android.view.View

Here is the full project on github

Just multiply the number by -1 and check if the result is positive.
