You can try something like this:

    <script type="text/javascript">
        function simulateLogin(userName)
        {
            var userNameField = document.getElementById("username");
            userNameField.value = userName;
            var goButton = document.getElementById("go");
            goButton.click();
        }

        simulateLogin("testUser");
</script>

I'm on OSX 10.10.2, and succeeded in using JPype.

Ran into installation problems with Jnius (others have too), Javabridge installed but gave mysterious errors when I tried to use it, PyJ4 has this inconvenience of having to start a Gateway server in Java first, JCC wouldn't install. Finally, JPype ended up working. There's a maintained fork of JPype on Github. It has the major advantages that (a) it installs properly and (b) it can very efficiently convert java arrays to numpy array (np_arr = java_arr[:])

The installation process was:

git clone https://github.com/originell/jpype.git
cd jpype
python setup.py install

And you should be able to import jpype

The following demo worked:

import jpype as jp
jp.startJVM(jp.getDefaultJVMPath(), "-ea")
jp.java.lang.System.out.println("hello world")
jp.shutdownJVM() 

When I tried calling my own java code, I had to first compile (javac ./blah/HelloWorldJPype.java), and I had to change the JVM path from the default (otherwise you'll get inexplicable "class not found" errors). For me, this meant changing the startJVM command to:

jp.startJVM('/Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/MacOS/libjli.dylib', "-ea")
c = jp.JClass('blah.HelloWorldJPype')  
# Where my java class file is in ./blah/HelloWorldJPype.class
...

Drop the spaces around the = sign:

#!/bin/bash 
STR="Hello World" 
echo $STR 

What directory is file.txt in? cron runs jobs in your home directory, so unless your script cds somewhere else, that's where it's going to look for/create file.txt.

EDIT: When you refer to a file without specifying its full path (e.g. file.txt, as opposed to the full path /home/myUser/scripts/file.txt) in shell, it's taken that you're referring to a file in your current working directory. When you run a script (whether interactively or via crontab), the script's working directory has nothing at all to do with the location of the script itself; instead, it's inherited from whatever ran the script.

Thus, if you cd (change working directory) to the directory the script's in and then run it, file.txt will refer to a file in the same directory as the script. But if you don't cd there first, file.txt will refer to a file in whatever directory you happen to be in when you ran the script. For instance, if your home directory is /home/myUser, and you open a new shell and immediately run the script (as scripts/test.sh or /home/myUser/scripts/test.sh; ./test.sh won't work), it'll touch the file /home/myUser/file.txt because /home/myUser is your current working directory (and therefore the script's).

When you run a script from cron, it does essentially the same thing: it runs it with the working directory set to your home directory. Thus all file references in the script are taken relative to your home directory, unless the script cds somewhere else or specifies an absolute path to the file.

Default options are read from the following files in the given order:

/etc/my.cnf 
/etc/mysql/my.cnf 
/usr/local/etc/my.cnf 
~/.my.cnf

If you want them to be displayed side by side, why is sideContent the child of mainContent? make them siblings then use:

float:left; display:inline; width: 49%;

on both of them.

#mainContent, #sideContent {float:left; display:inline; width: 49%;}

The code is okay but you are in the wrong directory. You must run these commands inside your rails project-directory.

The normal way to get there from scratch is:

$ rails new PROJECT_NAME
$ cd PROJECT_NAME
$ rails generate model ad \
    name:string \ 
    description:text \
    price:decimal \
    seller_id:integer \
    email:string img_url:string

Here is how you set the date and time:

update user set expiry_date=TO_DATE('31/DEC/2017 12:59:59', 'dd/mm/yyyy hh24:mi:ss') where id=123;

You can still use g++ directly if you want:

g++ f1.cpp f2.cpp main.cpp

where f1.cpp and f2.cpp are the files with the functions in them. For details of how to use make to do the build, see the excellent GNU make documentation.

I found this method in the documentation for the DictionaryBase class on MSDN:

foreach (DictionaryEntry de in myDictionary)
{
     //Do some stuff with de.Value or de.Key
}

This was the only one I was able to get functioning correctly in a class that inherited from the DictionaryBase.

You can use ref.

import ChildForm from './components/ChildForm'

new Vue({
  el: '#app',
  data: {
    item: {}
  },
  template: `
  <div>
     <ChildForm :item="item" ref="form" />
     <button type="submit" @click.prevent="submit">Post</button>
  </div>
  `,
  methods: {
    submit() {
      this.$refs.form.submit()
    }
  },
  components: { ChildForm },
})

If you dislike tight coupling, you can use Event Bus as shown by @Yosvel Quintero. Below is another example of using event bus by passing in the bus as props.

import ChildForm from './components/ChildForm'

new Vue({
  el: '#app',
  data: {
    item: {},
    bus: new Vue(),
  },
  template: `
  <div>
     <ChildForm :item="item" :bus="bus" ref="form" />
     <button type="submit" @click.prevent="submit">Post</button>
  </div>
  `,
  methods: {
    submit() {
      this.bus.$emit('submit')
    }
  },
  components: { ChildForm },
})

Code of component.

<template>
 ...
</template>

<script>
export default {
  name: 'NowForm',
  props: ['item', 'bus'],
  methods: {
    submit() {
        ...
    }
  },
  mounted() {
    this.bus.$on('submit', this.submit)
  },  
}
</script>

The lambda's in c++ are treated as "on the go available function". yes its literally on the go, you define it; use it; and as the parent function scope finishes the lambda function is gone.

c++ introduced it in c++ 11 and everyone started using it like at every possible place. the example and what is lambda can be find here https://en.cppreference.com/w/cpp/language/lambda

i will describe which is not there but essential to know for every c++ programmer

Lambda is not meant to use everywhere and every function cannot be replaced with lambda. It's also not the fastest one compare to normal function. because it has some overhead which need to be handled by lambda.

it will surely help in reducing number of lines in some cases. it can be basically used for the section of code, which is getting called in same function one or more time and that piece of code is not needed anywhere else so that you can create standalone function for it.

Below is the basic example of lambda and what happens in background.

User code:

int main()
{
  // Lambda & auto
  int member=10;
  auto endGame = [=](int a, int b){ return a+b+member;};

  endGame(4,5);

  return 0;

}

How compile expands it:

int main()
{
  int member = 10;

  class __lambda_6_18
  {
    int member;
    public: 
    inline /*constexpr */ int operator()(int a, int b) const
    {
      return a + b + member;
    }

    public: __lambda_6_18(int _member)
    : member{_member}
    {}

  };

  __lambda_6_18 endGame = __lambda_6_18{member};
  endGame.operator()(4, 5);

  return 0;
}

so as you can see, what kind of overhead it adds when you use it. so its not good idea to use them everywhere. it can be used at places where they are applicable.

According to documentation you're correct (http://php.net/manual/en/pdo.connections.php):

The connection remains active for the lifetime of that PDO object. To close the connection, you need to destroy the object by ensuring that all remaining references to it are deleted--you do this by assigning NULL to the variable that holds the object. If you don't do this explicitly, PHP will automatically close the connection when your script ends.

Note that if you initialise the PDO object as a persistent connection it will not automatically close the connection.

This function gets the series names, puts them into an array, sorts the array and based on that defines the plotting order which will give the desired output.

Function Increasing_Legend_Sort(mychart As Chart)


    Dim Arr()
    ReDim Arr(1 To mychart.FullSeriesCollection.Count)

        'Assigning Series names to an array
        For i = LBound(Arr) To UBound(Arr)
        Arr(i) = mychart.FullSeriesCollection(i).Name
        Next i

        'Bubble-Sort (Sort the array in increasing order)
        For r1 = LBound(Arr) To UBound(Arr)
            rval = Arr(r1)
                For r2 = LBound(Arr) To UBound(Arr)
                    If Arr(r2) > rval Then 'Change ">" to "<" to make it decreasing
                        Arr(r1) = Arr(r2)
                        Arr(r2) = rval
                        rval = Arr(r1)
                    End If
                Next r2
        Next r1

    'Defining the PlotOrder
    For i = LBound(Arr) To UBound(Arr)
    mychart.FullSeriesCollection(Arr(i)).PlotOrder = i
    Next i

End Function

There are two things to consider: users can modify forms, and you need to secure against Cross Site Scripting (XSS).

XSS

XSS is when a user enters HTML into their input. For example, what if a user submitted this value?:

" /><script type="text/javascript" src="http://example.com/malice.js"></script><input value="

This would be written into your form like so:

<input type="hidden" name="prova[]" value="" /><script type="text/javascript" src="http://example.com/malice.js"></script><input value=""/>

The best way to protect against this is to use htmlspecialchars() to secure your input. This encodes characters such as < into <. For example:

<input type="hidden" name="prova[]" value="<?php echo htmlspecialchars($array); ?>"/>

You can read more about XSS here: https://www.owasp.org/index.php/XSS

Form Modification

If I were on your site, I could use Chrome's developer tools or Firebug to modify the HTML of your page. Depending on what your form does, this could be used maliciously.

I could, for example, add extra values to your array, or values that don't belong in the array. If this were a file system manager, then I could add files that don't exist or files that contain sensitive information (e.g.: replace myfile.jpg with ../index.php or ../db-connect.php).

In short, you always need to check your inputs later to make sure that they make sense, and only use safe inputs in forms. A File ID (a number) is safe, because you can check to see if the number exists, then extract the filename from a database (this assumes that your database contains validated input). A File Name isn't safe, for the reasons described above. You must either re-validate the filename or else I could change it to anything.

From the documentation:

Dynamic web applications also need static files. That’s usually where the CSS and JavaScript files are coming from. Ideally your web server is configured to serve them for you, but during development Flask can do that as well. Just create a folder called static in your package or next to your module and it will be available at /static on the application.

To generate URLs for static files, use the special 'static' endpoint name:

url_for('static', filename='style.css')

The file has to be stored on the filesystem as static/style.css.

Since ES9, there's now a simpler, better way of getting all the matches, together with information about the capture groups, and their index:

const string = 'Mice like to dice rice';
const regex = /.ice/gu;
for(const match of string.matchAll(regex)) {
    console.log(match);
}

// ["mice", index: 0, input: "mice like to dice rice", groups: undefined]

// ["dice", index: 13, input: "mice like to dice rice", groups: undefined]

// ["rice", index: 18, input: "mice like to dice rice", groups: undefined]

It is currently supported in Chrome, Firefox, Opera. Depending on when you read this, check this link to see its current support.

If you want to do it from the command line and not built into the script itself, use:

.\myscript.ps1 | Out-File c:\output.csv

Surprise surprise, rebooting solved the issue (I thought I had already tried that).

The solution Robert Crovella mentioned in the comments may also be useful to someone else, since it's pretty similar to what I did to solve the issue the first time I had it.

You need a Python DictReader class. More help can be found from here

import csv

with open('file_name.csv', 'rt') as f:
    reader = csv.DictReader(f)
    for row in reader:
        print row

you can use always:

'C:/mydir'

this works both in linux and windows. Other posibility is

'C:\\mydir'

if you have problems with some names you can also try raw string literals:

r'C:\mydir'

however best practice is to use the os.path module functions that always select the correct configuration for your OS:

os.path.join(mydir, myfile)

From python 3.4 you can also use the pathlib module. This is equivelent to the above:

pathlib.Path(mydir, myfile)

or

pathlib.Path(mydir) / myfile

Add this style to your span:

position:relative; 
top: 10px;

Demo: http://jsfiddle.net/BqTUS/3/

select * from xxx where dates between '2012-10-10' and '2012-10-12'

I always use YYYY-MM-DD in my views and never had any issue. Plus, it is readable and non equivocal.
You should be aware that using BETWEEN might not return what you expect with a DATETIME field, since it would eliminate records dated '2012-10-12 08:00' for example.
I would rather use where dates >= '2012-10-10' and dates < '2012-10-13' (lower than next day)

First you need to know the exact name of the INDEX (Unique key in this case) to delete or update it.
INDEX names are usually same as column names. In case of more than one INDEX applied on a column, MySQL automatically suffixes numbering to the column names to create unique INDEX names.

For example if 2 indexes are applied on a column named customer_id

1. The first index will be named as customer_id itself.
2. The second index will be names as customer_id_2 and so on.

To know the name of the index you want to delete or update

SHOW INDEX FROM <table_name>

as suggested by @Amr

To delete an index

ALTER TABLE <table_name> DROP INDEX <index_name>;

I think you are looking for below code changes:

<select name="course">
<option value="0">Please Select Option</option>
<option value="PHP" <?php if($options=="PHP") echo 'selected="selected"'; ?> >PHP</option>
<option value="ASP" <?php if($options=="ASP") echo 'selected="selected"'; ?> >ASP</option>
</select>

I'm late to the party but I found some useful instructions in github help page and I wanted to share them here.

Sometimes, Git can't make your change to a remote repository without losing commits. When this happens, your push is refused.

If another person has pushed to the same branch as you, Git won't be able to push your changes:

$ git push origin master
To https://github.com/USERNAME/REPOSITORY.git
 ! [rejected]        master -> master (non-fast-forward)
error: failed to push some refs to 'https://github.com/USERNAME/REPOSITORY.git'
To prevent you from losing history, non-fast-forward updates were rejected
Merge the remote changes (e.g. 'git pull') before pushing again.  See the
'Note about fast-forwards' section of 'git push --help' for details.

You can fix this by fetching and merging the changes made on the remote branch with the changes that you have made locally:

$ git fetch origin
# Fetches updates made to an online repository
$ git merge origin YOUR_BRANCH_NAME
# Merges updates made online with your local work

Or, you can simply use git pull to perform both commands at once:

$ git pull origin YOUR_BRANCH_NAME
# Grabs online updates and merges them with your local work

In nutshell,

@Pathparam works for value passing through both Resources and Query String

• /user/1
• /user?id=1

@Queryparam works for value passing only Query String

• /user?id=1

On Mavericks I install it from the node pkg (from nodejs site) and I uninstall it so I can re-install using brew. I only run 4 commands in the terminal:

1. sudo rm -rf /usr/local/lib/node_modules/npm/
2. brew uninstall node
3. brew doctor
4. brew cleanup --prune-prefix

If there is still a node installation, repeat step 2. After all is ok, I install using brew install node

As lyyons pointed out in the comments, more idiomatic and lodashy way to do this would be to use _.remove, like this

_.remove(obj.subTopics, {
    subTopicId: stToDelete
});

Apart from that, you can pass a predicate function whose result will be used to determine if the current element has to be removed or not.

_.remove(obj.subTopics, function(currentObject) {
    return currentObject.subTopicId === stToDelete;
});

Alternatively, you can create a new array by filtering the old one with _.filter and assign it to the same object, like this

obj.subTopics = _.filter(obj.subTopics, function(currentObject) {
    return currentObject.subTopicId !== stToDelete;
});

Or

obj.subTopics = _.filter(obj.subTopics, {subTopicId: stToKeep});

you can use the simpleDateFormat to parse the string date.

50 Meg is the max for Cell data download.

But you might be able to keep it under that in the app store and then have the app download other content after the user install and runs the app, so the app can be bigger. But not sure what the apple rules are for this.

I know that all in-app purchases need to be approved, but not sure if this kind of content needs to be approved.

I have had a similar issue in iOS 8, 9 and 10 and the info above couldn't fix it, however I did discover a solution after a day of working on this. Granted it won't work for everyone but in my case my items were stacked in a column and had 0 height when it should have been content height. Switching the css to be row and wrap fixed the issue. This only works if you have a single item and they are stacked but since it took me a day to find this out I thought I should share my fix!

.wrapper {
    flex-direction: column; // <-- Remove this line
    flex-direction: row; // <-- replace it with
    flex-wrap: wrap; // <-- Add wrapping
}

.item {
    width: 100%;
}

There was a bug in iOS 6, that causes line height to be ignored when font is set. See answer to NSParagraphStyle line spacing ignored and longer bug analysis at Radar: UITextView Ignores Minimum/Maximum Line Height in Attributed String.

For just counting the lines use:

$handle = fopen("file","r");
static $b = 0;
while($a = fgets($handle)) {
    $b++;
}
echo $b;

Here is the simple explanation of Redux over Flux. Redux does not have a dispatcher.It relies on pure functions called reducers. It does not need a dispatcher. Each actions are handled by one or more reducers to update the single store. Since data is immutable, reducers returns a new updated state that updates the store

For more information Flux vs Redux

is null is the syntax I use for such things, when COALESCE is of no help.

Try:

if (@zipCode is null)
  begin
    ([Portal].[dbo].[Address].Position.Filter(@radiusBuff) = 1)   
  end
else 
  begin
    ([Portal].[dbo].[Address].PostalCode=@zipCode )
  end  

This is a very c# type of code:

var bks: Book[] = new Book[2];

In Javascript / Typescript you don't allocate memory up front like that, and that means something completely different. This is how you would do what you want to do:

var bks: Book[] = [];
bks.push(new Book());
bks[0].Author = "vamsee";
bks[0].BookId = 1;
return bks.length;

Now to explain what new Book[2]; would mean. This would actually mean that call the new operator on the value of Book[2]. e.g.:

Book[2] = function (){alert("hey");}
var foo = new Book[2]

and you should see hey. Try it

In order to view only first few entries you can use, pandas head function which is used as

dataframe.head(any number)        // default is 5
dataframe.head(n=value)

or you can also you slicing for this purpose, which can also give the same result,

dataframe[:n]

In order to view the last few entries you can use pandas tail() in a similar way,

dataframe.tail(any number)        // default is 5
dataframe.tail(n=value)

You could use .dropna() if it is OK to drop the rows with the NaN values.

df = df.dropna(subset=['id'])

Alternatively, use .fillna() and .astype() to replace the NaN with values and convert them to int.

I ran into this problem when processing a CSV file with large integers, while some of them were missing (NaN). Using float as the type was not an option, because I might loose the precision.

My solution was to use str as the intermediate type. Then you can convert the string to int as you please later in the code. I replaced NaN with 0, but you could choose any value.

df = pd.read_csv(filename, dtype={'id':str})
df["id"] = df["id"].fillna("0").astype(int)

For the illustration, here is an example how floats may loose the precision:

s = "12345678901234567890"
f = float(s)
i = int(f)
i2 = int(s)
print (f, i, i2)

And the output is:

1.2345678901234567e+19 12345678901234567168 12345678901234567890

In iOS 11 there is a method that tells when the safeArea has changed.

override func viewSafeAreaInsetsDidChange() {
    super.viewSafeAreaInsetsDidChange()
    let top = view.safeAreaInsets.top
    let bottom = view.safeAreaInsets.bottom
}

The provided answers do not work in Firefox (Quantum). The event listener needs to be changed from mousewheel to wheel:

$(':input[type=number]').on('wheel',function(e){ $(this).blur(); });

This code works on Firefox Quantum and Chrome.

Maybe you have a file/directory named test in the directory. If this directory exists, and has no dependencies that are more recent, then this target is not rebuild.

To force rebuild on these kind of not-file-related targets, you should make them phony as follows:

.PHONY: all test clean

Note that you can declare all of your phony targets there.

A phony target is one that is not really the name of a file; rather it is just a name for a recipe to be executed when you make an explicit request.

\b\d{1,6}\b

Explanation

\b    # word boundary - start
\d    # any digits between 0 to 9 (inclusive)
{1,6} # length - min 1 digit or max 6 digits
\b    # word boundary - end

Much like jdsumsion's answer you can also stash your current work but then use a difftool like meld to pull selected changes from the stash. That way you can even edit the hunks manually very easy, which is a bit of a pain when in git add -p:

$ git stash -u
$ git difftool -d -t meld stash
$ git commit -a -m "some message"
$ git stash pop

Using the stash method gives you the opportunity to test, if your code still works, before you commit it.

For rails 3 :

request.fullpath

If you have a successful build, and getting a "Launch Binary not Found" Error. Try doing the following steps :

Click on Run -> Run Configuration -> C/C++ Application -> click on project_name debug -> click on browse and select your project file -> Press Ok -> below it Browse binary file ( Goto your Eclipse Workspace and select your project file -> You'll find two files 1.Debug 2.Src -> Click on Debug file -> Next click on the file with your project name and Press ok) -> then click apply and press run button.

This should solve the problem

I was also stuck in this situation where nested patterns comes.

Regular Expression is right thing to solve the above problem. Use below pattern

'/(\((?>[^()]+|(?1))*\))/'

Assuming the MyEjbProject is not another Maven Project you own or want to build with maven, you could use system dependencies to link to the existing jar file of the project like so

<project>
   ...
   <dependencies>
      <dependency>
         <groupId>yourgroup</groupId>
         <artifactId>myejbproject</artifactId>
         <version>2.0</version>
         <scope>system</scope>
         <systemPath>path/to/myejbproject.jar</systemPath>
      </dependency>
   </dependencies>
   ...
</project>

That said it is usually the better (and preferred way) to install the package to the repository either by making it a maven project and building it or installing it the way you already seem to do.

If they are, however, dependent on each other, you can always create a separate parent project (has to be a "pom" project) declaring the two other projects as its "modules". (The child projects would not have to declare the third project as their parent). As a consequence you'd get a new directory for the new parent project, where you'd also quite probably put the two independent projects like this:

parent
|- pom.xml
|- MyEJBProject
|   `- pom.xml
`- MyWarProject
    `- pom.xml

The parent project would get a "modules" section to name all the child modules. The aggregator would then use the dependencies in the child modules to actually find out the order in which the projects are to be built)

<project>
   ...
   <artifactId>myparentproject</artifactId>
   <groupId>...</groupId>
   <version>...</version>

   <packaging>pom</packaging>
   ...
   <modules>
     <module>MyEJBModule</module>
     <module>MyWarModule</module>
   </modules>
   ...
</project>

That way the projects can relate to each other but (once they are installed in the local repository) still be used independently as artifacts in other projects

Finally, if your projects are not in related directories, you might try to give them as relative modules:

filesystem
 |- mywarproject
 |   `pom.xml
 |- myejbproject
 |   `pom.xml
 `- parent
     `pom.xml

now you could just do this (worked in maven 2, just tried it):

<!--parent-->
<project>
  <modules>
    <module>../mywarproject</module>
    <module>../myejbproject</module>
  </modules>
</project>

If you added the key-string pairs in Info.plist (see Murat's answer above ) and still getting the error, try to check if the target you're currently working on has the keys.

In my case I had 2 targets (dev and development). I added the keys in the editor, but it only works for the main target and I was testing on development target. So I had to open XCode, click on the project > Info > Add the key-pair for the development target there.

Here is what you need to do. First make sure you are in branch that you don't want to pull. For example if you have master and develop branch, and you are trying to pull develop branch then stay in master branch.

git checkout master

Then,

git pull origin develop

You can use domaintools.com to lookup the server information for a website and narrow down to whether it's open source / Microsoft:

http://whois.domaintools.com/stackoverflow.com

And after that it's a matter of looking in the footer for tip-offs such as "Powered by WordPress" or "vBulletin" etc.

std::map::find returns an iterator to the found element (or to the end() if the element was not found). So long as the map is not const, you can modify the element pointed to by the iterator:

std::map<char, int> m;
m.insert(std::make_pair('c', 0));  // c is for cookie

std::map<char, int>::iterator it = m.find('c'); 
if (it != m.end())
    it->second = 42;

Leveraging David Dehghan's answer above, the following works in Python 2.7.13:

from PyPDF2 import PdfFileWriter, PdfFileReader, PdfFileMerger

import StringIO

from reportlab.pdfgen import canvas
from reportlab.lib.pagesizes import letter

packet = StringIO.StringIO()
# create a new PDF with Reportlab
can = canvas.Canvas(packet, pagesize=letter)
can.drawString(290, 720, "Hello world")
can.save()

#move to the beginning of the StringIO buffer
packet.seek(0)
new_pdf = PdfFileReader(packet)
# read your existing PDF
existing_pdf = PdfFileReader("original.pdf")
output = PdfFileWriter()
# add the "watermark" (which is the new pdf) on the existing page
page = existing_pdf.getPage(0)
page.mergePage(new_pdf.getPage(0))
output.addPage(page)
# finally, write "output" to a real file
outputStream = open("destination.pdf", "wb")
output.write(outputStream)
outputStream.close()

I use one Factory module that contains one (or more) constructor per class which calls the Init member of each class.

For example a Point class:

Class Point
Private X, Y
Sub Init(X, Y)
  Me.X = X
  Me.Y = Y
End Sub

A Line class

Class Line
Private P1, P2
Sub Init(Optional P1, Optional P2, Optional X1, Optional X2, Optional Y1, Optional Y2)
  If P1 Is Nothing Then
    Set Me.P1 = NewPoint(X1, Y1)
    Set Me.P2 = NewPoint(X2, Y2)
  Else
    Set Me.P1 = P1
    Set Me.P2 = P2
  End If
End Sub

And a Factory module:

Module Factory
Function NewPoint(X, Y)
  Set NewPoint = New Point
  NewPoint.Init X, Y
End Function

Function NewLine(Optional P1, Optional P2, Optional X1, Optional X2, Optional Y1, Optional Y2)
  Set NewLine = New Line
  NewLine.Init P1, P2, X1, Y1, X2, Y2
End Function

Function NewLinePt(P1, P2)
  Set NewLinePt = New Line
  NewLinePt.Init P1:=P1, P2:=P2
End Function

Function NewLineXY(X1, Y1, X2, Y2)
  Set NewLineXY = New Line
  NewLineXY.Init X1:=X1, Y1:=Y1, X2:=X2, Y2:=Y2
End Function

One nice aspect of this approach is that makes it easy to use the factory functions inside expressions. For example it is possible to do something like:

D = Distance(NewPoint(10, 10), NewPoint(20, 20)

or:

D = NewPoint(10, 10).Distance(NewPoint(20, 20))

It's clean: the factory does very little and it does it consistently across all objects, just the creation and one Init call on each creator.

And it's fairly object oriented: the Init functions are defined inside the objects.

EDIT

I forgot to add that this allows me to create static methods. For example I can do something like (after making the parameters optional):

NewLine.DeleteAllLinesShorterThan 10

Unfortunately a new instance of the object is created every time, so any static variable will be lost after the execution. The collection of lines and any other static variable used in this pseudo-static method must be defined in a module.

string mypath = @"..\folder1\folder2\folder2";
string[] directories = mypath.Split(Path.DirectorySeparatorChar);

Edit: This returns each individual folder in the directories array. You can get the number of folders returned like this:

int folderCount = directories.Length;

Within your template, you can use Django's date filter. E.g.:

<p>Birthday: {{ birthday|date:"M d, Y" }}</p>

Gives:

Birthday: Jan 29, 1983

More formatting examples in the date filter docs.

You can do the same with .ix, like this:

In [1]: df = pd.DataFrame(np.random.randn(5,4), columns=list('abcd'))

In [2]: df
Out[2]: 
          a         b         c         d
0 -0.323772  0.839542  0.173414 -1.341793
1 -1.001287  0.676910  0.465536  0.229544
2  0.963484 -0.905302 -0.435821  1.934512
3  0.266113 -0.034305 -0.110272 -0.720599
4 -0.522134 -0.913792  1.862832  0.314315

In [3]: df.ix[df.a>0, ['b','c']] = 0

In [4]: df
Out[4]: 
          a         b         c         d
0 -0.323772  0.839542  0.173414 -1.341793
1 -1.001287  0.676910  0.465536  0.229544
2  0.963484  0.000000  0.000000  1.934512
3  0.266113  0.000000  0.000000 -0.720599
4 -0.522134 -0.913792  1.862832  0.314315

EDIT

After the extra information, the following will return all columns - where some condition is met - with halved values:

>> condition = df.a > 0
>> df[condition][[i for i in df.columns.values if i not in ['a']]].apply(lambda x: x/2)

I hope this helps!

It may be concluded from answers here that NOT IN (subquery) doesn't handle nulls correctly and should be avoided in favour of NOT EXISTS. However, such a conclusion may be premature. In the following scenario, credited to Chris Date (Database Programming and Design, Vol 2 No 9, September 1989), it is NOT IN that handles nulls correctly and returns the correct result, rather than NOT EXISTS.

Consider a table sp to represent suppliers (sno) who are known to supply parts (pno) in quantity (qty). The table currently holds the following values:

      VALUES ('S1', 'P1', NULL), 
             ('S2', 'P1', 200),
             ('S3', 'P1', 1000)

Note that quantity is nullable i.e. to be able to record the fact a supplier is known to supply parts even if it is not known in what quantity.

The task is to find the suppliers who are known supply part number 'P1' but not in quantities of 1000.

The following uses NOT IN to correctly identify supplier 'S2' only:

WITH sp AS 
     ( SELECT * 
         FROM ( VALUES ( 'S1', 'P1', NULL ), 
                       ( 'S2', 'P1', 200 ),
                       ( 'S3', 'P1', 1000 ) )
              AS T ( sno, pno, qty )
     )
SELECT DISTINCT spx.sno
  FROM sp spx
 WHERE spx.pno = 'P1'
       AND 1000 NOT IN (
                        SELECT spy.qty
                          FROM sp spy
                         WHERE spy.sno = spx.sno
                               AND spy.pno = 'P1'
                       );

However, the below query uses the same general structure but with NOT EXISTS but incorrectly includes supplier 'S1' in the result (i.e. for which the quantity is null):

WITH sp AS 
     ( SELECT * 
         FROM ( VALUES ( 'S1', 'P1', NULL ), 
                       ( 'S2', 'P1', 200 ),
                       ( 'S3', 'P1', 1000 ) )
              AS T ( sno, pno, qty )
     )
SELECT DISTINCT spx.sno
  FROM sp spx
 WHERE spx.pno = 'P1'
       AND NOT EXISTS (
                       SELECT *
                         FROM sp spy
                        WHERE spy.sno = spx.sno
                              AND spy.pno = 'P1'
                              AND spy.qty = 1000
                      );

So NOT EXISTS is not the silver bullet it may have appeared!

Of course, source of the problem is the presence of nulls, therefore the 'real' solution is to eliminate those nulls.

This can be achieved (among other possible designs) using two tables:

• sp suppliers known to supply parts
• spq suppliers known to supply parts in known quantities

noting there should probably be a foreign key constraint where spq references sp.

The result can then be obtained using the 'minus' relational operator (being the EXCEPT keyword in Standard SQL) e.g.

WITH sp AS 
     ( SELECT * 
         FROM ( VALUES ( 'S1', 'P1' ), 
                       ( 'S2', 'P1' ),
                       ( 'S3', 'P1' ) )
              AS T ( sno, pno )
     ),
     spq AS 
     ( SELECT * 
         FROM ( VALUES ( 'S2', 'P1', 200 ),
                       ( 'S3', 'P1', 1000 ) )
              AS T ( sno, pno, qty )
     )
SELECT sno
  FROM spq
 WHERE pno = 'P1'
EXCEPT 
SELECT sno
  FROM spq
 WHERE pno = 'P1'
       AND qty = 1000;

I'm not sure about your first code sample where you use WebClient.UploadValues, it's not really enough to go on, could you paste more of your surrounding code? Regarding your WebRequest code, there are two things at play here:

1. You're only requesting the headers of the response**, you never read the body of the response by opening and reading (to its end) the ResponseStream. Because of this, the WebRequest client helpfully leaves the connection open, expecting you to request the body at any moment. Until you either read the response body to completion (which will automatically close the stream for you), clean up and close the stream (or the WebRequest instance) or wait for the GC to do its thing, your connection will remain open.

2. You have a default maximum amount of active connections to the same host of 2. This means you use up your first two connections and then never dispose of them so your client isn't given the chance to complete the next request before it reaches its timeout (which is milliseconds, btw, so you've set it to 0.2 seconds - the default should be fine).

If you don't want the body of the response (or you've just uploaded or POSTed something and aren't expecting a response), simply close the stream, or the client, which will close the stream for you.

The easiest way to fix this is to make sure you use using blocks on disposable objects:

for (int i = 0; i < ops1; i++)
{
    Uri myUri = new Uri(site);
    WebRequest myWebRequest = WebRequest.Create(myUri);
    //myWebRequest.Timeout = 200;
    using (WebResponse myWebResponse = myWebRequest.GetResponse())
    {
        // Do what you want with myWebResponse.Headers.
    } // Your response will be disposed of here
}

Another solution is to allow 200 concurrent connections to the same host. However, unless you're planning to multi-thread this operation so you'd need multiple, concurrent connections, this won't really help you:

 ServicePointManager.DefaultConnectionLimit = 200;

When you're getting timeouts within code, the best thing to do is try to recreate that timeout outside of your code. If you can't, the problem probably lies with your code. I usually use cURL for that, or just a web browser if it's a simple GET request.

** In reality, you're actually requesting the first chunk of data from the response, which contains the HTTP headers, and also the start of the body. This is why it's possible to read HTTP header info (such as Content-Encoding, Set-Cookie etc) before reading from the output stream. As you read the stream, further data is retrieved from the server. WebRequest's connection to the server is kept open until you reach the end of this stream (effectively closing it as it's not seekable), manually close it yourself or it is disposed of. There's more about this here.

I had a similar error "Specified cast is not valid" restoring from SQL Server 2012 to SQL Server 2008 R2

First I got the MDF and LDF Names:

RESTORE FILELISTONLY 
FROM  DISK = N'C:\Users\dell laptop\DotNetSandBox\DBBackups\Davincis3.bak' 
GO

Second I restored with a MOVE using those names returned:

RESTORE DATABASE Davincis3 
FROM DISK = 'C:\Users\dell laptop\DotNetSandBox\DBBackups\Davincis3.bak'
WITH 
   MOVE 'JQueryExampleDb' TO 'C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\DATA\Davincis3.mdf', 
   MOVE 'JQueryExampleDB_log' TO 'C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\DATA\Davincis3.ldf', 
REPLACE
GO  

I have no clue as to the name "JQueryExampleDb", but this worked for me.

Nevertheless, backups (and databases) are not backwards compatible with older versions.

I would do it this way

 $("#idElement").val('optionValue').trigger('change');

This solution doesn't require you to use any data structures or make a different file.

Basically, you define all your enum values in a #define, then use them in the operator <<. Very similar to @jxh's answer.

ideone link for final iteration: http://ideone.com/hQTKQp

Full code:

#include <iostream>

#define ERROR_VALUES ERROR_VALUE(NO_ERROR)\
ERROR_VALUE(FILE_NOT_FOUND)\
ERROR_VALUE(LABEL_UNINITIALISED)

enum class Error
{
#define ERROR_VALUE(NAME) NAME,
    ERROR_VALUES
#undef ERROR_VALUE
};

inline std::ostream& operator<<(std::ostream& os, Error err)
{
    int errVal = static_cast<int>(err);
    switch (err)
    {
#define ERROR_VALUE(NAME) case Error::NAME: return os << "[" << errVal << "]" #NAME;
    ERROR_VALUES
#undef ERROR_VALUE
    default:
        // If the error value isn't found (shouldn't happen)
        return os << errVal;
    }
}

int main() {
    std::cout << "Error: " << Error::NO_ERROR << std::endl;
    std::cout << "Error: " << Error::FILE_NOT_FOUND << std::endl;
    std::cout << "Error: " << Error::LABEL_UNINITIALISED << std::endl;
    return 0;
}

Output:

Error: [0]NO_ERROR
Error: [1]FILE_NOT_FOUND
Error: [2]LABEL_UNINITIALISED

A nice thing about doing it this way is that you can also specify your own custom messages for each error if you think you need them:

#include <iostream>

#define ERROR_VALUES ERROR_VALUE(NO_ERROR, "Everything is fine")\
ERROR_VALUE(FILE_NOT_FOUND, "File is not found")\
ERROR_VALUE(LABEL_UNINITIALISED, "A component tried to the label before it was initialised")

enum class Error
{
#define ERROR_VALUE(NAME,DESCR) NAME,
    ERROR_VALUES
#undef ERROR_VALUE
};

inline std::ostream& operator<<(std::ostream& os, Error err)
{
    int errVal = static_cast<int>(err);
    switch (err)
    {
#define ERROR_VALUE(NAME,DESCR) case Error::NAME: return os << "[" << errVal << "]" #NAME <<"; " << DESCR;
    ERROR_VALUES
#undef ERROR_VALUE
    default:
        return os << errVal;
    }
}

int main() {
    std::cout << "Error: " << Error::NO_ERROR << std::endl;
    std::cout << "Error: " << Error::FILE_NOT_FOUND << std::endl;
    std::cout << "Error: " << Error::LABEL_UNINITIALISED << std::endl;
    return 0;
}

Output:

Error: [0]NO_ERROR; Everything is fine
Error: [1]FILE_NOT_FOUND; File is not found
Error: [2]LABEL_UNINITIALISED; A component tried to the label before it was initialised

If you like making your error codes/descriptions very descriptive, you might not want them in production builds. Turning them off so only the value is printed is easy:

inline std::ostream& operator<<(std::ostream& os, Error err)
{
    int errVal = static_cast<int>(err);
    switch (err)
    {
    #ifndef PRODUCTION_BUILD // Don't print out names in production builds
    #define ERROR_VALUE(NAME,DESCR) case Error::NAME: return os << "[" << errVal << "]" #NAME <<"; " << DESCR;
        ERROR_VALUES
    #undef ERROR_VALUE
    #endif
    default:
        return os << errVal;
    }
}

Output:

Error: 0
Error: 1
Error: 2

If this is the case, finding error number 525 would be a PITA. We can manually specify the numbers in the initial enum like this:

#define ERROR_VALUES ERROR_VALUE(NO_ERROR, 0, "Everything is fine")\
ERROR_VALUE(FILE_NOT_FOUND, 1, "File is not found")\
ERROR_VALUE(LABEL_UNINITIALISED, 2, "A component tried to the label before it was initialised")\
ERROR_VALUE(UKNOWN_ERROR, -1, "Uh oh")

enum class Error
{
#define ERROR_VALUE(NAME,VALUE,DESCR) NAME=VALUE,
    ERROR_VALUES
#undef ERROR_VALUE
};

inline std::ostream& operator<<(std::ostream& os, Error err)
{
    int errVal = static_cast<int>(err);
    switch (err)
    {
#ifndef PRODUCTION_BUILD // Don't print out names in production builds
#define ERROR_VALUE(NAME,VALUE,DESCR) case Error::NAME: return os << "[" #VALUE  "]" #NAME <<"; " << DESCR;
    ERROR_VALUES
#undef ERROR_VALUE
#endif
    default:
        return os <<errVal;
    }
}
    ERROR_VALUES
#undef ERROR_VALUE
#endif
    default:
    {
        // If the error value isn't found (shouldn't happen)
        return os << static_cast<int>(err);
        break;
    }
    }
}

Output:

Error: [0]NO_ERROR; Everything is fine
Error: [1]FILE_NOT_FOUND; File is not found
Error: [2]LABEL_UNINITIALISED; A component tried to the label before it was initialised
Error: [-1]UKNOWN_ERROR; Uh oh

The documentation on counting says that for group_by queries it is better to use func.count():

from sqlalchemy import func
session.query(Table.column, func.count(Table.column)).group_by(Table.column).all()

You need to call self.a() to invoke a from b. a is not a global function, it is a method on the class.

You may want to read through the Python tutorial on classes some more to get the finer details down.

These instructions worked for me on apache-tomcat-8.5.20 on mac os 10.13.3 using jdk1.8.0_152:

$ cd /path/to/apache-tomcat-8.5.20/bin

$ ./catalina.sh jpda run

Now connect to port 12321 from IntelliJ/Eclipse and enjoy remote debugging.

This is a warning, But addressing this will make Reacts rendering much FASTER,

This is because React needs to uniquely identify each items in the list. Lets say if the state of an element of that list changes in Reacts Virtual DOM then React needs to figure out which element got changed and where in the DOM it needs to change so that browser DOM will be in sync with the Reacts Virtual DOM.

As a solution just introduce a key attribute to each li tag. This key should be a unique value to each element.

The for loop is getting one extra run. Change

for (x=0;x<=InvForm.SelBranch.length;x++)

to

for (x=0; x < InvForm.SelBranch.length; x++)

Also you can position the other window before withdrawing it so that you position your message

from tkinter import *
import tkinter.messagebox

window = Tk()
window.wm_withdraw()

# message at x:200,y:200
window.geometry("1x1+200+200")  # remember its.geometry("WidthxHeight(+or-)X(+or-)Y")
tkinter.messagebox.showerror(title="error", message="Error Message", parent=window)

# center screen message
window.geometry(f"1x1+{round(window.winfo_screenwidth() / 2)}+{round(window.winfo_screenheight() / 2)}")
tkinter.messagebox.showinfo(title="Greetings", message="Hello World!")

Please Note: This is Lewis Cowles' answer just Python 3ified, since tkinter has changed since python 2. If you want your code to be backwords compadible do something like this:

try:
    import tkinter
    import tkinter.messagebox
except ModuleNotFoundError:
    import Tkinter as tkinter
    import tkMessageBox as tkinter.messagebox

There you have it, null-safe invocation in Java 8:

public void someMethod() {
    String userName = nullIfAbsent(new Order(), t -> t.getAccount().getUser()
        .getName());
}

static <T, R> R nullIfAbsent(T t, Function<T, R> funct) {
    try {
        return funct.apply(t);
    } catch (NullPointerException e) {
        return null;
    }
}

Might be better to use a choice, don't have to type (or possibly mistype) your expressions more than once, and allows you to follow additional different behaviors.

I very often use count(/html/body) = 0, as the specific number of nodes is more interesting than the set. For example... when there is unexpectedly more than 1 node that matches your expression.

<xsl:choose>
    <xsl:when test="/html/body">
         <!-- Found the node(s) -->
    </xsl:when>
    <!-- more xsl:when here, if needed -->
    <xsl:otherwise>
         <!-- No node exists -->
    </xsl:otherwise>
</xsl:choose>

Forget float, margin and html 3/5. The mail is very obsolete. You need do all with table. One line = one table. You need margin or padding ? Do another column.

Codepen

Example : i need one line with 1 One Picture of 40*40 2 One margin of 10 px 3 One text of 400px

I start my line :

<table style=" background-repeat:no-repeat; width:450px;margin:0;" cellpadding="0" cellspacing="0" border="0">
   <tr style="height:40px; width:450px; margin:0;">
     <td style="height:40px; width:40px; margin:0;">
        <img src="" style="width=40px;height40;margin:0;display:block"
     </td>
     <td style="height:40px; width:10px; margin:0;">        
     </td>
     <td style="height:40px; width:400px; margin:0;">
     <p style=" margin:0;"> my text   </p>
     </td>
   </tr>
</table>

In c/cpp there is no shortcut but to initialize all the arrays with the zero subscript.Ex:

  int arr[10] = {0};

But in java there is a magic tool called Arrays.fill() which will fill all the values in an array with the integer of your choice.Ex:

  import java.util.Arrays;

    public class Main
    {
      public static void main(String[] args)
       {
         int ar[] = {2, 2, 1, 8, 3, 2, 2, 4, 2};
         Arrays.fill(ar, 10);
         System.out.println("Array completely filled" +                          
            " with 10\n" + Arrays.toString(ar));
   }
 }

to get first and last element from foreach array

foreach($array as $value) {
    if ($value === reset($array)) {
        echo 'FIRST ELEMENT!';
    }

    if ($value === end($array)) {
        echo 'LAST ITEM!';
    }
}

In Java side, the date is usually represented by the (poorly designed, but that aside) java.util.Date. It is basically backed by the Epoch time in flavor of a long, also known as a timestamp. It contains information about both the date and time parts. In Java, the precision is in milliseconds.

In SQL side, there are several standard date and time types, DATE, TIME and TIMESTAMP (at some DB's also called DATETIME), which are represented in JDBC as java.sql.Date, java.sql.Time and java.sql.Timestamp, all subclasses of java.util.Date. The precision is DB dependent, often in milliseconds like Java, but it can also be in seconds.

In contrary to java.util.Date, the java.sql.Date contains only information about the date part (year, month, day). The Time contains only information about the time part (hours, minutes, seconds) and the Timestamp contains information about the both parts, like as java.util.Date does.

The normal practice to store a timestamp in the DB (thus, java.util.Date in Java side and java.sql.Timestamp in JDBC side) is to use PreparedStatement#setTimestamp().

java.util.Date date = getItSomehow();
Timestamp timestamp = new Timestamp(date.getTime());
preparedStatement = connection.prepareStatement("SELECT * FROM tbl WHERE ts > ?");
preparedStatement.setTimestamp(1, timestamp);

The normal practice to obtain a timestamp from the DB is to use ResultSet#getTimestamp().

Timestamp timestamp = resultSet.getTimestamp("ts");
java.util.Date date = timestamp; // You can just upcast.

For the beginners:

Null coalescing operator (??)

Everything is true except null values and undefined (variable/array index/object attributes)

ex:

$array = [];
$object = new stdClass();

var_export (false ?? 'second');                           # false
var_export (true  ?? 'second');                           # true
var_export (null  ?? 'second');                           # 'second'
var_export (''    ?? 'second');                           # ""
var_export ('some text'    ?? 'second');                  # "some text"
var_export (0     ?? 'second');                           # 0
var_export ($undefinedVarible ?? 'second');               # "second"
var_export ($array['undefined_index'] ?? 'second');       # "second"
var_export ($object->undefinedAttribute ?? 'second');     # "second"

this is basically check the variable(array index, object attribute.. etc) is exist and not null. similar to isset function

Ternary operator shorthand (?:)

every false things (false,null,0,empty string) are come as false, but if it's a undefined it also come as false but Notice will throw

ex

$array = [];
$object = new stdClass();

var_export (false ?: 'second');                           # "second"
var_export (true  ?: 'second');                           # true
var_export (null  ?: 'second');                           # "second"
var_export (''    ?: 'second');                           # "second"
var_export ('some text'    ?? 'second');                  # "some text"
var_export (0     ?: 'second');                           # "second"
var_export ($undefinedVarible ?: 'second');               # "second" Notice: Undefined variable: ..
var_export ($array['undefined_index'] ?: 'second');       # "second" Notice: Undefined index: ..
var_export ($object->undefinedAttribute ?: 'second');     # "Notice: Undefined index: ..

Hope this helps

You could use the load()-event in jQuery but it won't always fire if the image is loaded from the browser cache. This plugin https://github.com/peol/jquery.imgloaded/raw/master/ahpi.imgload.js can be used to remedy that problem.

Yes, it's possible. But first read, "What happens when I change my username?"

To change your username, click your profile picture in the top right corner, then click Settings. On the left side, click Account. Then click Change username.

This error might occur when you return an object instead of a string in your __unicode__ method. For example:

class Author(models.Model):
    . . . 
    name = models.CharField(...)


class Book(models.Model):
    . . .
    author = models.ForeignKey(Author, ...)
    . . .
    def __unicode__(self):
        return self.author  # <<<<<<<< this causes problems

To avoid this error you can cast the author instance to unicode:

class Book(models.Model):
    . . . 
    def __unicode__(self):
        return unicode(self.author)  # <<<<<<<< this is OK

If you want to insert other string somewhere else in existing string, you may use selection method below.

Calling character on second position:

>>> s = "0123456789"
>>> s[2]
'2'

Calling range with start and end position:

>>> s[4:6]
'45'

Calling part of a string before that position:

>>> s[:6]
'012345'

Calling part of a string after that position:

>>> s[4:]
'456789'

Inserting your string in 5th position.

>>> s = s[:5] + "L" + s[5:]
>>> s
'01234L56789'

Also s is equivalent to s[:].

With your question you can use all your string, i.e.

>>> s = "L" + s + "LL"

or if "L" is a some other string (for example I call it as l), then you may use that code:

>>> s = l + s + (l * 2)

I have written a script as *.sh file

#!/bin/sh
set -x
FTPHOST='host-address'
FTPUSER='ftp-username'
FTPPASSWD='yourPass'

ftp -n -v $FTPHOST << EOT
ascii
user $FTPUSER $FTPPASSWD
prompt
##Your commands

Works fine for me

Sometimes the column you are looking for may be part of the name of many other things that you are not interested in.

For example I was recently looking for a column called "BQR", which also forms part of many other columns such as "BQR_OWNER", "PROP_BQR", etc.

So I would like to have the checkbox that word processors have to indicate "Whole words only".

Unfortunately LIKE has no such functionality, but REGEXP_LIKE can help.

SELECT *
  FROM user_source
 WHERE regexp_like(text, '(\s|\.|,|^)bqr(\s|,|$)');

This is the regular expression to find this column and exclude the other columns with "BQR" as part of the name:

(\s|\.|,|^)bqr(\s|,|$)

The regular expression matches white-space (\s), or (|) period (.), or (|) comma (,), or (|) start-of-line (^), followed by "bqr", followed by white-space, comma or end-of-line ($).

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

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

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

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

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

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

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

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

An IntPtr is a value type that is primarily used to hold memory addresses or handles. A pointer is a memory address. A pointer can be typed (e.g. int*) or untyped (e.g. void*). A Windows handle is a value that is usually the same size (or smaller) than a memory address and represents a system resource (like a file or window).

Just loop...

foreach(var table in DataSet1.Tables) {
    foreach(var col in table.Columns) {
       ...
    }
    foreach(var row in table.Rows) {
        object[] values = row.ItemArray;
        ...
    }
}

The most complete (and correct) way of doing this would be, I believe:

if (old_key !== new_key) {
    Object.defineProperty(o, new_key,
        Object.getOwnPropertyDescriptor(o, old_key));
    delete o[old_key];
}

This method ensures that the renamed property behaves identically to the original one.

Also, it seems to me that the possibility to wrap this into a function/method and put it into Object.prototype is irrelevant regarding your question.

Both System.Timers.Timer and System.Threading.Timer will work for services.

The timers you want to avoid are System.Web.UI.Timer and System.Windows.Forms.Timer, which are respectively for ASP applications and WinForms. Using those will cause the service to load an additional assembly which is not really needed for the type of application you are building.

Use System.Timers.Timer like the following example (also, make sure that you use a class level variable to prevent garbage collection, as stated in Tim Robinson's answer):

using System;
using System.Timers;

public class Timer1
{
    private static System.Timers.Timer aTimer;

    public static void Main()
    {
        // Normally, the timer is declared at the class level,
        // so that it stays in scope as long as it is needed.
        // If the timer is declared in a long-running method,  
        // KeepAlive must be used to prevent the JIT compiler 
        // from allowing aggressive garbage collection to occur 
        // before the method ends. (See end of method.)
        //System.Timers.Timer aTimer;

        // Create a timer with a ten second interval.
        aTimer = new System.Timers.Timer(10000);

        // Hook up the Elapsed event for the timer.
        aTimer.Elapsed += new ElapsedEventHandler(OnTimedEvent);

        // Set the Interval to 2 seconds (2000 milliseconds).
        aTimer.Interval = 2000;
        aTimer.Enabled = true;

        Console.WriteLine("Press the Enter key to exit the program.");
        Console.ReadLine();

        // If the timer is declared in a long-running method, use
        // KeepAlive to prevent garbage collection from occurring
        // before the method ends.
        //GC.KeepAlive(aTimer);
    }

    // Specify what you want to happen when the Elapsed event is 
    // raised.
    private static void OnTimedEvent(object source, ElapsedEventArgs e)
    {
        Console.WriteLine("The Elapsed event was raised at {0}", e.SignalTime);
    }
}

/* This code example produces output similar to the following:

Press the Enter key to exit the program.
The Elapsed event was raised at 5/20/2007 8:42:27 PM
The Elapsed event was raised at 5/20/2007 8:42:29 PM
The Elapsed event was raised at 5/20/2007 8:42:31 PM
...
 */

If you choose System.Threading.Timer, you can use as follows:

using System;
using System.Threading;

class TimerExample
{
    static void Main()
    {
        AutoResetEvent autoEvent     = new AutoResetEvent(false);
        StatusChecker  statusChecker = new StatusChecker(10);

        // Create the delegate that invokes methods for the timer.
        TimerCallback timerDelegate = 
            new TimerCallback(statusChecker.CheckStatus);

        // Create a timer that signals the delegate to invoke 
        // CheckStatus after one second, and every 1/4 second 
        // thereafter.
        Console.WriteLine("{0} Creating timer.\n", 
            DateTime.Now.ToString("h:mm:ss.fff"));
        Timer stateTimer = 
                new Timer(timerDelegate, autoEvent, 1000, 250);

        // When autoEvent signals, change the period to every 
        // 1/2 second.
        autoEvent.WaitOne(5000, false);
        stateTimer.Change(0, 500);
        Console.WriteLine("\nChanging period.\n");

        // When autoEvent signals the second time, dispose of 
        // the timer.
        autoEvent.WaitOne(5000, false);
        stateTimer.Dispose();
        Console.WriteLine("\nDestroying timer.");
    }
}

class StatusChecker
{
    int invokeCount, maxCount;

    public StatusChecker(int count)
    {
        invokeCount  = 0;
        maxCount = count;
    }

    // This method is called by the timer delegate.
    public void CheckStatus(Object stateInfo)
    {
        AutoResetEvent autoEvent = (AutoResetEvent)stateInfo;
        Console.WriteLine("{0} Checking status {1,2}.", 
            DateTime.Now.ToString("h:mm:ss.fff"), 
            (++invokeCount).ToString());

        if(invokeCount == maxCount)
        {
            // Reset the counter and signal Main.
            invokeCount  = 0;
            autoEvent.Set();
        }
    }
}

I tend to follow the design of JDK libraries, especially Collections and Concurrency (Joshua Bloch, Doug Lea, those guys know how to design solid APIs). Anyway, many APIs in the JDK pro-actively throws NullPointerException.

For example, the Javadoc for Map.containsKey states:

@throws NullPointerException if the key is null and this map does not permit null keys (optional).

It's perfectly valid to throw your own NPE. The convention is to include the parameter name which was null in the message of the exception.

The pattern goes:

public void someMethod(Object mustNotBeNull) {  
    if (mustNotBeNull == null) {  
        throw new NullPointerException("mustNotBeNull must not be null");  
    }  
}

Whatever you do, don't allow a bad value to get set and throw an exception later when other code attempts to use it. That makes debugging a nightmare. You should always the follow the "fail-fast" principle.

While loop syntax example in MySQL:

Should it not be foreach instead of for!?

Fastest solution to render DOM from string:

let render = (relEl, tpl, parse = true) => {
  if (!relEl) return;
  const range = document.createRange();
  range.selectNode(relEl);
  const child = range.createContextualFragment(tpl);
  return parse ? relEl.appendChild(child) : {relEl, el};
};

And here u can check performance for DOM manipulation React vs native JS

Now u can simply use:

let element = render(document.body, `
<div style="font-size:120%;line-height:140%">
  <p class="bold">New DOM</p>
</div>
`);

And of course in near future u use references from memory cause var "element" is your new created DOM in your document.

And remember "innerHTML=" is very slow :/

The easiest way would probably be to convert the array into a java.util.ArrayList. Once it is in an arraylist, you can easily leverage the contains method.

public static boolean bagOfWords(String str)
{
    String[] words = {"word1", "word2", "word3", "word4", "word5"};  
    return (Arrays.asList(words).contains(str));
}

Great question: How does our differ from my and what does our do?

In Summary:

Available since Perl 5, my is a way to declare non-package variables, that are:

• private
• new
• non-global
• separate from any package, so that the variable cannot be accessed in the form of $package_name::variable.

On the other hand, our variables are package variables, and thus automatically:

• global variables
• definitely not private
• not necessarily new
• can be accessed outside the package (or lexical scope) with the qualified namespace, as $package_name::variable.

Declaring a variable with our allows you to predeclare variables in order to use them under use strict without getting typo warnings or compile-time errors. Since Perl 5.6, it has replaced the obsolete use vars, which was only file-scoped, and not lexically scoped as is our.

For example, the formal, qualified name for variable $x inside package main is $main::x. Declaring our $x allows you to use the bare $x variable without penalty (i.e., without a resulting error), in the scope of the declaration, when the script uses use strict or use strict "vars". The scope might be one, or two, or more packages, or one small block.

Find the server option in the window-->preferences and add server as you need

This doesn't work too well when you have the plugin placed in a thin column, like a sidebar for example. On medium sized screens these typically run smaller than 280px in width.

.fb-page, 
.fb-page span, 
.fb-page span iframe[style] { 
    width: 100% !important; 
}

This is the code I use to stop the plugin breaking outside of a wrapping container. Unlike the old like box which would tile, this one just overflows, hiding the overflowed content.

add this at the top of file,

header('content-type: application/json; charset=utf-8');
header("access-control-allow-origin: *");

From Maven - Settings Reference

The repositories for download and deployment are defined by the repositories and distributionManagement elements of the POM. However, certain settings such as username and password should not be distributed along with the pom.xml. This type of information should exist on the build server in the settings.xml.

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
                  http://maven.apache.org/xsd/settings-1.0.0.xsd">
  ...
  <servers>
    <server>
      <id>server001</id>
      <username>my_login</username>
      <password>my_password</password>
      <privateKey>${user.home}/.ssh/id_dsa</privateKey>
      <passphrase>some_passphrase</passphrase>
      <filePermissions>664</filePermissions>
      <directoryPermissions>775</directoryPermissions>
      <configuration></configuration>
    </server>
  </servers>
  ...
</settings>

id: This is the ID of the server (not of the user to login as) that matches the id element of the repository/mirror that Maven tries to connect to.

username, password: These elements appear as a pair denoting the login and password required to authenticate to this server.

privateKey, passphrase: Like the previous two elements, this pair specifies a path to a private key (default is ${user.home}/.ssh/id_dsa) and a passphrase, if required. The passphrase and password elements may be externalized in the future, but for now they must be set plain-text in the settings.xml file.

filePermissions, directoryPermissions: When a repository file or directory is created on deployment, these are the permissions to use. The legal values of each is a three digit number corrosponding to *nix file permissions, ie. 664, or 775.

Note: If you use a private key to login to the server, make sure you omit the element. Otherwise, the key will be ignored.

All you should need is the id, username and password

The id and URL should be defined in your pom.xml like this:

<repositories>
    ...
    <repository>
        <id>acme-nexus-releases</id>
        <name>acme nexus</name>
        <url>https://nexus.acme.net/content/repositories/releases</url>
    </repository>
    ...
</repositories>

If you need a username and password to your server, you should encrypt it. Maven Password Encryption

Other answers have described why it's not needed for iterators, but sometimes it is useful when assigning to increase a variable in-line, you can achieve the same effect using tuples and multiple assignment:

b = ++a becomes:

a,b = (a+1,)*2

and b = a++ becomes:

a,b = a+1, a

Python 3.8 introduces the assignment := operator, allowing us to achievefoo(++a) with

foo(a:=a+1)

foo(a++) is still elusive though.

"find '-maxdepth' " does not work with my old version of bash, therefore I use:

for f in $(ls) ; do if [ -f $f ] ; then echo $f ; fi ; done

The answers above are correct, and what I'd consider the "best" answers. But just to be as complete as possible, you can also do this directly in CF using queryAddColumn.

See http://www.cfquickdocs.com/cf9/#queryaddcolumn

Again, it's more efficient to do it at the database level... but it's good to be aware of as many alternatives as possible (IMO, of course) :)

CSS lets you use custom fonts, downloadable fonts on your website. You can download the font of your preference, let’s say myfont.ttf, and upload it to your remote server where your blog or website is hosted.

@font-face {
    font-family: myfont;
    src: url('myfont.ttf');
}

This is just a sample code, but it may help you get on your way:

Public Sub testIt()
    Workbooks("Workbook2").Activate
    ActiveWorkbook.Sheets("Sheet2").Activate
    ActiveSheet.Range("B3").Select
    ActiveCell.EntireRow.Insert
End Sub

I am assuming that you can open the book (called Workbook2 in the example).

I think (but I'm not sure) you can squash all this in a single line of code:

    Workbooks("Workbook2").Sheets("Sheet2").Range("B3").EntireRow.Insert

This way you won't need to activate the workbook (or sheet or cell)... Obviously, the book has to be open.

You can also simply avoid using numeric IDs as Primary Key. You could use Country codes as primary id if the table holds countries information, or you could use permalinks, if it hold articles for example.

You could also simply use a random, or an MD5 value. All this options have it's own benefits, specially on IT sec. numeric IDs are easy to enumerate.

Use Entry.insert. For example:

try:
    from tkinter import *  # Python 3.x
except Import Error:
    from Tkinter import *  # Python 2.x

root = Tk()
e = Entry(root)
e.insert(END, 'default text')
e.pack()
root.mainloop()

Or use textvariable option:

try:
    from tkinter import *  # Python 3.x
except Import Error:
    from Tkinter import *  # Python 2.x

root = Tk()
v = StringVar(root, value='default text')
e = Entry(root, textvariable=v)
e.pack()
root.mainloop()

If you want to sum certain columns only, I'd use something like this:

library(dplyr)
df=data.frame(
  x1=c(1,0,0,NA,0,1,1,NA,0,1),
  x2=c(1,1,NA,1,1,0,NA,NA,0,1),
  x3=c(0,1,0,1,1,0,NA,NA,0,1),
  x4=c(1,0,NA,1,0,0,NA,0,0,1),
  x5=c(1,1,NA,1,1,1,NA,1,0,1))
df %>% select(x3:x5) %>% rowSums(na.rm=TRUE) -> df$x3x5.total
head(df)

This way you can use dplyr::select's syntax.

You could:

• Define a userStatus parameter for the child component and provide the value when using this component from the parent:

  @Component({
    (...)
  })
  export class Profile implements OnInit {
    @Input()
    userStatus:UserStatus;
  
    (...)
  }
  

  and in the parent:

  <profile [userStatus]="userStatus"></profile>
  

• Inject the parent into the child component:

  @Component({
    (...)
  })
  export class Profile implements OnInit {
    constructor(app:App) {
      this.userStatus = app.userStatus;
    }
  
    (...)
  }
  

  Be careful about cyclic dependencies between them.

Just wanted to add that while:

git checkout -b {branchName}

Creates a new branch, it also checks out that branch / makes it your current branch. If, for some reason, all you want to do is snap off a branch but not make it your current branch, then you would use the following command:

git branch {branchName}

In the first command, "checkout" makes said branch your current branch, and the "-b" means: this branch doesn't exist yet, so make it for me.

dtypes is a Pandas Series. That means it contains index & values attributes. If you only need the column names:

headers = df.dtypes.index

it will return a list containing the column names of "df" dataframe.

After doing some research found the solution. Run the below command.

echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p

For Arch Linux add this line to /etc/sysctl.d/99-sysctl.conf:

fs.inotify.max_user_watches=524288

Here's the most cross-browser solution.

This is better than the accepted answer because it uses native Object.keys if exists. Thus, it is the fastest for all modern browsers.

if (!Object.keys) {
    Object.keys = function (obj) {
        var arr = [],
            key;
        for (key in obj) {
            if (obj.hasOwnProperty(key)) {
                arr.push(key);
            }
        }
        return arr;
    };
}

Object.keys(obj).length;

Here is a rough explanation of the concepts.

[ACK] is the acknowledgement that the previously sent data packet was received.

[FIN] is sent by a host when it wants to terminate the connection; the TCP protocol requires both endpoints to send the termination request (i.e. FIN).

So, suppose

• host A sends a data packet to host B
• and then host B wants to close the connection.
• Host B (depending on timing) can respond with [FIN,ACK] indicating that it received the sent packet and wants to close the session.
• Host A should then respond with a [FIN,ACK] indicating that it received the termination request (the ACK part) and that it too will close the connection (the FIN part).

However, if host A wants to close the session after sending the packet, it would only send a [FIN] packet (nothing to acknowledge) but host B would respond with [FIN,ACK] (acknowledges the request and responds with FIN).

Finally, some TCP stacks perform half-duplex termination, meaning that they can send [RST] instead of the usual [FIN,ACK]. This happens when the host actively closes the session without processing all the data that was sent to it. Linux is one operating system which does just this.

You can find a more detailed and comprehensive explanation here.

Supposing the form is the direct parent you can do:

<a href='#' onclick='this.parentNode.submit(); return false;'>submit</a>

If not you can access through the forms name attribute like this:

<a href='#' onclick='document.forms["myform"].submit(); return false;'>submit</a>

See both examples here: http://jsfiddle.net/WEZDC/1/

To run something every 10 minutes past the hour.

from datetime import datetime, timedelta

while 1:
    print 'Run something..'

    dt = datetime.now() + timedelta(hours=1)
    dt = dt.replace(minute=10)

    while datetime.now() < dt:
        time.sleep(1)

The standard function atoi() will likely do what you want.

A simple example using "atoi":

#include <unistd.h>

int main(int argc, char *argv[])
{
    int useconds = atoi(argv[1]); 
    usleep(useconds);
}

Following up to @steven-anderson you can also configure passwords inside the ant.properties, so the process can be fully automated

so if you put in platform\android\ant.properties the following

key.store=../../yourCertificate.jks
key.store.password=notSoSecretPassword
key.alias=userAlias
key.alias.password=notSoSecretPassword

Swift 4

    let flow = collectionView.collectionViewLayout as! UICollectionViewFlowLayout 
    // If you create collectionView programmatically then just create this flow by UICollectionViewFlowLayout() and init a collectionView by this flow.

    let itemSpacing: CGFloat = 3
    let itemsInOneLine: CGFloat = 3
    flow.sectionInset = UIEdgeInsets(top: 0, left: 0, bottom: 0, right: 0)

    //collectionView.frame.width is the same as  UIScreen.main.bounds.size.width here.
    let width = UIScreen.main.bounds.size.width - itemSpacing * CGFloat(itemsInOneLine - 1) 
    flow.itemSize = CGSize(width: floor(width/itemsInOneLine), height: width/itemsInOneLine)
    flow.minimumInteritemSpacing = 3
    flow.minimumLineSpacing = itemSpacing

EDIT

If you want to change to scrollDirction horizontally:

flow.scrollDirection = .horizontal

NOTE

If you set items in one lines isn't correctly, check if your collection view has paddings. That is:

let width = UIScreen.main.bounds.size.width - itemSpacing * CGFloat(itemsInOneLine - 1)

should be the collectionView width.

I had this error for my XXX element and it was because my XSD was wrongly formatted according to javax.xml.bind v2.2.11 . I think it's using an older XSD format but I didn't bother to confirm.

My initial wrong XSD was alike the following:

<xs:element name="Document" type="Document"/>
...
<xs:complexType name="Document">
    <xs:sequence>
        <xs:element name="XXX" type="XXX_TYPE"/>
    </xs:sequence>
</xs:complexType>

The good XSD format for my migration to succeed was the following:

<xs:element name="Document">
    <xs:complexType>
        <xs:sequence>
            <xs:element ref="XXX"/>
        </xs:sequence>
    </xs:complexType>        
</xs:element>
...
<xs:element name="XXX" type="XXX_TYPE"/>

And so on for every similar XSD nodes.

I believe that javac behaviour has changed - with 1.5 it prohibited the annotation, with 1.6 it doesn't. The annotation provides an extra compile-time check, so if you're using 1.6 I'd go for it.

Another thing you can do is just drag a folder from your computer into the GitHub repository page. This folder does have to have at least 1 item in it, though.

      let myRequest = URLRequest(url: myURL!)
      webView.load(myRequest)
   }
   override func loadView() {
      let webConfiguration = WKWebViewConfiguration()
      webView = WKWebView(frame: .zero, configuration: webConfiguration)
      webView.uiDelegate = self
      view = webView
   }

And that is why you can't create a bot with JavaScript, because your options are limited to what the browser allows you to do. You can't just order a browser that follows the CORS policy, which most browsers follow, to send random requests to other origins and allow you to get the response that simply!

Additionally, if you tried to edit some request headers manually, like origin-header from the developers tools that come with the browsers, the browser will refuse your edit and may send a preflight OPTIONS request.

Get all contacts in less than a second and without any load in your activity. Follow my steps works like a charm.

ArrayList<Contact> contactList = new ArrayList<>();

private static final String[] PROJECTION = new String[]{
        ContactsContract.CommonDataKinds.Phone.CONTACT_ID,
        ContactsContract.Contacts.DISPLAY_NAME,
        ContactsContract.CommonDataKinds.Phone.NUMBER
};

private void getContactList() {
    ContentResolver cr = getContentResolver();

    Cursor cursor = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, PROJECTION, null, null, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + " ASC");
    if (cursor != null) {
        HashSet<String> mobileNoSet = new HashSet<String>();
        try {
            final int nameIndex = cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME);
            final int numberIndex = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);

            String name, number;
            while (cursor.moveToNext()) {
                name = cursor.getString(nameIndex);
                number = cursor.getString(numberIndex);
                number = number.replace(" ", "");
                if (!mobileNoSet.contains(number)) {
                    contactList.add(new Contact(name, number));
                    mobileNoSet.add(number);
                    Log.d("hvy", "onCreaterrView  Phone Number: name = " + name
                            + " No = " + number);
                }
            }
        } finally {
            cursor.close();
        }
    }
}

Contacts

public class Contact {
public String name;
public String phoneNumber;

public Contact() {
}

public Contact(String name, String phoneNumber ) {
    this.name = name;
    this.phoneNumber = phoneNumber;
}

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

public String getPhoneNumber() {
    return phoneNumber;
}

public void setPhoneNumber(String phoneNumber) {
    this.phoneNumber = phoneNumber;
}

}

Benefits

• less than a second
• without load
• ascending order
• without duplicate contacts

Gson 1.6 now includes a low-level streaming API and a new parser which is actually faster than Jackson.

Simply use the .rules('add') method immediately after creating the element...

var filenumber = 1;
$("#AddFile").click(function () { //User clicks button #AddFile

    // create the new input element
    $('<li><input type="file" name="FileUpload' + filenumber + '" id="FileUpload' + filenumber + '" /> <a href="#" class="RemoveFileUpload">Remove</a></li>').prependTo("#FileUploader");

    // declare the rule on this newly created input field        
    $('#FileUpload' + filenumber).rules('add', {
        required: true,  // <- with this you would not need 'required' attribute on input
        accept: "image/jpeg, image/pjpeg"
    });

    filenumber++; // increment counter for next time

    return false;
});

• You'll still need to use .validate() to initialize the plugin within a DOM ready handler.

• You'll still need to declare rules for your static elements using .validate(). Whatever input elements that are part of the form when the page loads... declare their rules within .validate().

• You don't need to use .each(), when you're only targeting ONE element with the jQuery selector attached to .rules().

• You don't need the required attribute on your input element when you're declaring the required rule using .validate() or .rules('add'). For whatever reason, if you still want the HTML5 attribute, at least use a proper format like required="required".

Working DEMO: http://jsfiddle.net/8dAU8/5/

Judging by the source code for URI, the

public URL(URL context, String spec, URLStreamHandler handler)

constructor does more validation than the other constructors. You might try that one, but YMMV.

When you say pair[0], that gives you ("a", 1). The thing in parentheses is a tuple, which, like a list, is a type of collection. So you can access the first element of that thing by specifying [0] or [1] after its name. So all you have to do to get the first element of the first element of pair is say pair[0][0]. Or if you want the second element of the third element, it's pair[2][1].

https://support.ansible.com/hc/en-us/articles/201957837-How-do-I-split-an-action-into-a-multi-line-format-

mentions YAML line continuations.

As an example (tried with ansible 2.0.0.2):

---
- hosts: all
  tasks:
    - name: multiline shell command
      shell: >
        ls --color
        /home
      register: stdout

    - name: debug output
      debug: msg={{ stdout }}

The shell command is collapsed into a single line, as in ls --color /home

$(".divIDClass").hide();

To show Div Block

$(".divIDClass").show();

If you search for an image base-64 converter, you can embed some small image texture files as code into your @import url('') section of code. It will look like a lot of code; but at least all your data is now stored locally - rather than having to call a separate resource to load the image.

With your texture images, you'll want to employ a similar process.

sed -n '16224,16482p' < dump.sql

This can be done in SQL Server 2014+ provided the stored procedure only returns one table. If anyone finds a way of doing this for multiple tables I'd love to know about it.

DECLARE @storedProcname NVARCHAR(MAX) = ''
SET @storedProcname = 'myStoredProc'

DECLARE @strSQL AS VARCHAR(MAX) = 'CREATE TABLE myTableName '

SELECT @strSQL = @strSQL+STUFF((
SELECT ',' +name+' ' + system_type_name 
FROM sys.dm_exec_describe_first_result_set_for_object (OBJECT_ID(@storedProcname),0)
FOR XML PATH('')
),1,1,'(') + ')'

EXEC (@strSQL)

INSERT INTO myTableName

EXEC ('myStoredProc @param1=1, @param2=2')

SELECT * FROM myTableName

DROP TABLE myTableName

This pulls the definition of the returned table from system tables, and uses that to build the temp table for you. You can then populate it from the stored procedure as stated before.

There are also variants of this that work with Dynamic SQL too.

From the Javadoc:

Sometimes several tests need to share computationally expensive setup (like logging into a database). While this can compromise the independence of tests, sometimes it is a necessary optimization. Annotating a public static void no-arg method with @BeforeClass causes it to be run once before any of the test methods in the class. The @BeforeClass methods of superclasses will be run before those the current class.

AJAX is getting data from the server using Javascript and XML in an asynchronous fashion. Unless you want to download the colour code from the server, that's not what you're really aiming for!

But otherwise you can set the CSS background with Javascript. If you're using a framework like jQuery, it'll be something like this:

$('body').css('background', '#ccc');

Otherwise, this should work:

document.body.style.background = "#ccc";

I had this problem on my developent environment with Visual Studio.

What helped me was to Clean Solution in Visual Studio and then do a rebuild.

I know it's a bit late, but I've tried everything above and nothing worked. The real problem was that I'm using hibernate, so it was trying to connect to mysql but was not able, thats why it showed time out.

Just to let u guys know, I'm using RDS(Amazon), so just to make a test I changed to my local mysql and it worked perfectly.

Hope that this answer helps somebody.

Thanks.

Use map function

var values = $("input[name^='card']").map(function (idx, ele) {
   return $(ele).val();
}).get();

$.each(JSON.parse(result), function(i, item) {
    alert(item.number);
});

Installing Boost on Ubuntu with an example of using boost::array:

Install libboost-all-dev and aptitude:

sudo apt install libboost-all-dev

sudo apt install aptitude

aptitude search boost

Then paste this into a C++ file called main.cpp:

#include <iostream>
#include <boost/array.hpp>

using namespace std;
int main(){
  boost::array<int, 4> arr = {{1,2,3,4}};
  cout << "hi" << arr[0];
  return 0;
}

Compile like this:

g++ -o s main.cpp

Run it like this:

./s

Program prints:

hi1

By using the List property.

ListBox1.AddItem "foo"
ListBox1.List(ListBox1.ListCount - 1, 1) = "bar"

Try this it works!

For Those who are facing difficulty just got to php admin and change collation to utf8_general_ci Select Table go to Operations>> table options>> collations should be there

Use the Figure.savefig() method, like so:

ax = s.hist()  # s is an instance of Series
fig = ax.get_figure()
fig.savefig('/path/to/figure.pdf')

It doesn't have to end in pdf, there are many options. Check out the documentation.

Alternatively, you can use the pyplot interface and just call the savefig as a function to save the most recently created figure:

import matplotlib.pyplot as plt
s.hist()
plt.savefig('path/to/figure.pdf')  # saves the current figure

I'm also faced with this issue. So I solved with recursion. Maybe it will be helpfull. I created method.I used org.json library.

    public static JSONObject function(JSONObject obj, String keyMain, String newValue) throws Exception {
    // We need to know keys of Jsonobject
    Iterator iterator = obj.keys();
    String key = null;
    while (iterator.hasNext()) {
        key = (String) iterator.next();
        // if object is just string we change value in key
        if ((obj.optJSONArray(key)==null) && (obj.optJSONObject(key)==null)) {
            if ((key.equals(keyMain)) && (obj.get(key).toString().equals(valueMain))) {
                // put new value
                obj.put(key, newValue);
                return obj;
            }
        }

        // if it's jsonobject
        if (obj.optJSONObject(key) != null) {
            function(obj.getJSONObject(key), keyMain, valueMain, newValue);
        }

        // if it's jsonarray
        if (obj.optJSONArray(key) != null) {
            JSONArray jArray = obj.getJSONArray(key);
            for (int i=0;i<jArray.length();i++) {
                    function(jArray.getJSONObject(i), keyMain, valueMain, newValue);
            }
        }
    }
    return obj;
}

if you have questions, I can explain...

It's a designated initializer, introduced with the C99 standard; it allows you to initialize specific members of a struct or union object by name. my_data is obviously a typedef for a struct type that has a member name of type char * or char [N].

That's because if a class is abstract, then by definition you are required to create subclasses of it to instantiate. The subclasses will be required (by the compiler) to implement any interface methods that the abstract class left out.

Following your example code, try making a subclass of AbstractThing without implementing the m2 method and see what errors the compiler gives you. It will force you to implement this method.

You have to open as new StreamWriter(filename, true) so that it appends to the file instead of overwriting.

I wrote an article on topis how to [manually install curl on debian linu][1]x.

[1]: http://www.jasom.net/how-to-install-curl-command-manually-on-debian-linux. This is its shortcut:

1. cd /usr/local/src
2. wget http://curl.haxx.se/download/curl-7.36.0.tar.gz
3. tar -xvzf curl-7.36.0.tar.gz
4. rm *.gz
5. cd curl-7.6.0
6. ./configure
7. make
8. make install

And restart Apache. If you will have an error during point 6, try to run apt-get install build-essential.

ES6: Using async/await you can do below getMeta function in sequence-like way and you can use it as follows (which is almost identical to code in your question (I add await keyword and change variable end to img, and change var to let keyword). You need to run getMeta by await only from async function (run).

function getMeta(url) {
    return new Promise((resolve, reject) => {
        let img = new Image();
        img.onload = () => resolve(img);
        img.onerror = () => reject();
        img.src = url;
    });
}

async function run() {

  let img = await getMeta("http://shijitht.files.wordpress.com/2010/08/github.png");

  let w = img.width;
  let h = img.height; 

  size.innerText = `width=${w}px, height=${h}px`;
  size.appendChild(img);
}

run();

<div id="size" />

The method you are looking for is .limit.

Returns a new Dataset by taking the first n rows. The difference between this function and head is that head returns an array while limit returns a new Dataset.

Example usage:

df.limit(1000)

It sounds like you answered your own question. get_class will get you the class name. It is procedural and maybe that is what is causing the confusion. Take a look at the php documentation for get_class

Here is their example:

 <?php

 class foo 
 {
     function name()
     {
         echo "My name is " , get_class($this) , "\n";
     }
 }

 // create an object
 $bar = new foo();

 // external call
 echo "Its name is " , get_class($bar) , "\n"; // It's name is foo

 // internal call
 $bar->name(); // My name is foo

To make it more like your example you could do something like:

 <?php

 class MyClass
 {
       public static function getClass()
       {
            return get_class();
       }
 }

Now you can do:

 $className = MyClass::getClass();

This is somewhat limited, however, because if my class is extended it will still return 'MyClass'. We can use get_called_class instead, which relies on Late Static Binding, a relatively new feature, and requires PHP >= 5.3.

<?php

class MyClass
{
    public static function getClass()
    {
        return get_called_class();
    }

    public static function getDefiningClass()
    {
        return get_class();
    }
}

class MyExtendedClass extends MyClass {}

$className = MyClass::getClass(); // 'MyClass'
$className = MyExtendedClass::getClass(); // 'MyExtendedClass'
$className = MyExtendedClass::getDefiningClass(); // 'MyClass'

docker attach will let you connect to your Docker container, but this isn't really the same thing as ssh. If your container is running a webserver, for example, docker attach will probably connect you to the stdout of the web server process. It won't necessarily give you a shell.

The docker exec command is probably what you are looking for; this will let you run arbitrary commands inside an existing container. For example:

docker exec -it <mycontainer> bash

Of course, whatever command you are running must exist in the container filesystem.

In the above command <mycontainer> is the name or ID of the target container. It doesn't matter whether or not you're using docker compose; just run docker ps and use either the ID (a hexadecimal string displayed in the first column) or the name (displayed in the final column). E.g., given:

$ docker ps
d2d4a89aaee9        larsks/mini-httpd   "mini_httpd -d /cont   7 days ago          Up 7 days                               web                 

I can run:

$ docker exec -it web ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN 
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
18: eth0: <BROADCAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP 
    link/ether 02:42:ac:11:00:03 brd ff:ff:ff:ff:ff:ff
    inet 172.17.0.3/16 scope global eth0
       valid_lft forever preferred_lft forever
    inet6 fe80::42:acff:fe11:3/64 scope link 
       valid_lft forever preferred_lft forever

I could accomplish the same thing by running:

$ docker exec -it d2d4a89aaee9 ip addr

Similarly, I could start a shell in the container;

$ docker exec -it web sh
/ # echo This is inside the container.
This is inside the container.
/ # exit
$

@scottyab the parametrized DatabaseUtils.queryNumEntries(db, table, whereparams) exists at API 11 +, the one without the whereparams exists since API 1. The answer would have to be creating a Cursor with a db.rawQuery:

Cursor mCount= db.rawQuery("select count(*) from users where uname='" + loginname + "' and pwd='" + loginpass +"'", null);
mCount.moveToFirst();
int count= mCount.getInt(0);
mCount.close();

I also like @Dre's answer, with the parameterized query.

At startup pass this -Dname=value

and then in your code you should use

value=System.getProperty("name");

to get that value

This instruction works 100% for me:

1. Rename the Eclipse workspace name
2. Start Eclipse (it will start successfully with empty workspace)
3. Exit it and change workspace name to previous state(if ask to replace some files, press no)
4. Start Eclipse again and Re import projects in current workspace

Enjoy!

Check out Effective Java, 2nd edition page 27. Item 7: Avoid finalizers

Finalizers are unpredictable, often dangerous, and generally unnecessary. never do anything time-critical in a finalizer. never depend on a finalizer to update critical persistent state.

To terminate a resource, use try-finally instead:

// try-finally block guarantees execution of termination method
Foo foo = new Foo(...);
try {
    // Do what must be done with foo
    ...
} finally {
    foo.terminate(); // Explicit termination method
}

Use Null.NullInteger ex: private int _ReservationID = Null.NullInteger;

This works great if a straight copy is in order. If the situation calls for creating new objects from templates, I usually wrap the template div in a hidden storage div and use jquery's html() in conjunction with clone() applying the following technique:

<style>
#element-storage {
    display: none;
    top: 0;
    right: 0;
    position: fixed;
    width: 0;
    height: 0;
}
</style>

<script>
$("#new-div").append($("#template").clone().html(function(index, oldHTML){ 
    // .. code to modify template, e.g. below:
    var newHTML = "";
    newHTML = oldHTML.replace("[firstname]", "Tom");
    newHTML = newHTML.replace("[lastname]", "Smith");
    // newHTML = newHTML.replace(/[Example Replace String]/g, "Replacement"); // regex for global replace
    return newHTML;
}));
</script>

<div id="element-storage">
  <div id="template">
    <p>Hello [firstname] [lastname]</p>
  </div>
</div>

<div id="new-div">

</div>

Well, the most likely difference is that you still have to do an actual lookup of localhost somewhere.

If you use 127.0.0.1, then (intelligent) software will just turn that directly into an IP address and use it. Some implementations of gethostbyname will detect the dotted format (and presumably the equivalent IPv6 format) and not do a lookup at all.

Otherwise, the name has to be resolved. And there's no guarantee that your hosts file will actually be used for that resolution (first, or at all) so localhost may become a totally different IP address.

By that I mean that, on some systems, a local hosts file can be bypassed. The host.conf file controls this on Linux (and many other Unices).

First import sys in name-file.py

 import sys

Second append the folder path in name-file.py

sys.path.insert(0, '/the/folder/path/name-package/')

Third Make a blank file called __ init __.py in your subdirectory (this tells Python it is a package)

• name-file.py
• name-package
  • __ init __.py
  • name-module.py

Fourth import the module inside the folder in name-file.py

from name-package import name-module

try this:

var today = new Date();
var date = today.getFullYear()+'-'+(today.getMonth()+1)+'-'+today.getDate();
var time = today.getHours()+':'+today.getMinutes()+':'+today.getSeconds();
console.log(date + ' '+ time);

The above solution works perfectly. I prefer to choose Web API option while selecting the project template as shown in the picture below

Note: The solution works with Visual Studio 2013 or higher. The original question was asked in 2012 and it is 2016, therefore adding a solution Visual Studio 2013 or higher.

I had this same issue, I was passing a spring bean back as a ResponseBody object. When I handed back an object created by new, all was good.

I think it is fine because I've seen many people doing this way.

If you are just defining the event handler within the directive, you do not have to define it on the scope, though. Following would be fine.

myApp.directive('clickme', function() {
  return function(scope, element, attrs) {
    var clickingCallback = function() {
      alert('clicked!')
    };
    element.bind('click', clickingCallback);
  }
});

It's a lot more efficient to use the substr() method instead of split() & pop()

Have a look at the performance differences here: http://jsperf.com/remove-first-character-from-string

// returns: 'html'
var path = require('path');
path.extname('index.html').substr(1);

Update August 2019 As pointed out by @xentek in the comments; substr() is now considered a legacy function (MDN documentation). You can use substring() instead. The difference between substr() and substring() is that the second argument of substr() is the maximum length to return while the second argument of substring() is the index to stop at (without including that character). Also, substr() accepts negative start positions to be used as an offset from the end of the string while substring() does not.

The UnsupportedClassVersionError means that you are probably using (installed) an older version of Java as used to create the JAR.
Go to java.sun.com page, download and install a newer JRE (Java Runtime Environment).
if you want/need to develop with Java, you will need the JDK which includes the JRE.

Assuming you're dealing with Windows 7 x64 and something that was previously installed with some sort of an installer, you can open regedit and search the keys under

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall

(which references 32-bit programs) for part of the name of the program, or

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall

(if it actually was a 64-bit program).

If you find something that matches your program in one of those, the contents of UninstallString in that key usually give you the exact command you are looking for (that you can run in a script).

If you don't find anything relevant in those registry locations, then it may have been "installed" by unzipping a file. Because you mentioned removing it by the Control Panel, I gather this likely isn't then case; if it's in the list of programs there, it should be in one of the registry keys I mentioned.

Then in a .bat script you can do

if exist "c:\program files\whatever\program.exe" (place UninstallString contents here)
if exist "c:\program files (x86)\whatever\program.exe" (place UninstallString contents here)

You could instantiate "AnnotationConfigApplicationContext" by passing all your service classes as parameters.

@Component
public class MyServiceFactory {

    private ApplicationContext applicationContext;

    public MyServiceFactory() {
        applicationContext = new AnnotationConfigApplicationContext(
                MyServiceOne.class,
                MyServiceTwo.class,
                MyServiceThree.class,
                MyServiceDefault.class,
                LocationService.class 
        );
        /* I have added LocationService.class because this component is also autowired */
    }

    public MyService getMyService(String service) {

        if ("one".equalsIgnoreCase(service)) {
            return applicationContext.getBean(MyServiceOne.class);
        } 

        if ("two".equalsIgnoreCase(service)) {
            return applicationContext.getBean(MyServiceTwo.class);
        } 

        if ("three".equalsIgnoreCase(service)) {
            return applicationContext.getBean(MyServiceThree.class);
        } 

        return applicationContext.getBean(MyServiceDefault.class);
    }
}

You can also do this if you want to play around with pandas. However, I like punchagan's way.

# replicating your dataframe
lake = pd.DataFrame({'co tp': ['DE Lake', 'Forest', 'FR Lake', 'Forest'], 
                 'area': [10, 20, 30, 40], 
                 'count': [7, 5, 2, 3]})
lake.set_index('co tp', inplace=True)

# to get key value using pandas
area_dict = lake.set_index('area').T.to_dict('records')[0]
print(area_dict)

output: {10: 7, 20: 5, 30: 2, 40: 3}

_x000D_
  <p>Don’t use as a general approach for horizontal centering elements. The downside here is that the centered element will be removed from the document flow.

display: flex

.container {
  display: flex;
  justify-content: center;
}

Notes:

• It’s not a hack
• Browser support: flexbox

max-width & margin

You can horizontally center a block-level element by assigning a fixed width and setting margin-right and margin-left to auto.

.container ul {
  /* for IE below version 7 use `width` instead of `max-width` */
  max-width: 800px;
  margin-right: auto;
  margin-left: auto;
}

Notes:

• No container needed
• Requires (maximum) width of the centered element to be known

IE9+: transform: translatex(-50%) & left: 50%

This is similar to the quirky centering method which uses absolute positioning and negative margins.

.container {
  position: relative;
}

.container ul {
  position: absolute;
  left: 50%;
  transform: translatex(-50%);
}

Notes:

• The centered element will be removed from document flow. All elements will completely ignore of the centered element.
• This technique allows vertical centering by using top instead of left and translateY() instead of translateX(). The two can even be combined.
• Browser support: transform2d

IE8+: display: table & margin

Just like the first solution, you use auto values for right and left margins, but don’t assign a width. If you don’t need to support IE7 and below, this is better suited, although it feels kind of hacky to use the table property value for display.

.container ul {
  display: table;
  margin-right: auto;
  margin-left: auto;
}

IE8+: display: inline-block & text-align

Centering an element just like you would do with regular text is possible as well. Downside: You need to assign values to both a container and the element itself.

.container {
  text-align: center;
}

.container ul {
  display: inline-block;

  /* One most likely needs to realign flow content */
  text-align: initial;
}

Notes:

• Does not require to specify a (maximum) width
• Aligns flow content to the center (potentially unwanted side effect)
• Works kind of well with a dynamic number of menu items (i.e. in cases where you can’t know the width a single item will take up)

It is all about the right tool for the job. Neither is better 100% of the time. Both systems were created by man and have flaws. Sorry, but we suck and making perfect stuff.

I like dynamic typing because it gets out of my way, but yes runtime errors can creep up that I didn't plan for. Where as static typing may fix the aforementioned errors, but drive a novice(in typed languages) programmer crazy trying to cast between a constant char and a string.

HTML

<form method="post">
<textarea name="postes" id="textAreaPost" placeholder="Write what's you new" maxlength="500"></textarea>

<div id="char_namb" style="padding: 4px; float: right; font-size: 20px; font-family: Cocon; text-align: center;">500 : 0</div>
</form>

jQuery

$(function(){
    $('#textAreaPost').keyup(function(){
      var charsno = $(this).val().length;
      $('#char_namb').html("500 : " + charsno);
    });
});

I had similar problem. My header file which included the definition of the class wasn't working. I wasn't able to use the member functions of that class. So i simply copied my class to another header file. Now its working all ok.

Also check out the open financial exchange (ofx) http://www.ofx.net/

This is what apps like quicken, ms money etc use.

You should write textcolor in xml as

android:textColor="@color/text_color"

or

android:textColor="#FFFFFF"

Go to

C:\ drive

or that drive where xampp is installed click on xampp find php and open it , there you find php.ini folder open php.ini file with notepad and find upload_max_filesize and post_max_size in both "up and down find option",change both values to 1000M

Found a way of setting auto increment in netbeans 8.0.1 here on StackoOverflow Screenshot below:

This is an easy way to create custom events and raise them. You create a delegate and an event in the class you are throwing from. Then subscribe to the event from another part of your code. You have already got a custom event argument class so you can build on that to make other event argument classes. N.B: I have not compiled this code.

public partial class Form1 : Form
{
    private TestClass _testClass;
    public Form1()
    {
        InitializeComponent();
        _testClass = new TestClass();
        _testClass.OnUpdateStatus += new TestClass.StatusUpdateHandler(UpdateStatus);
    }

    private void UpdateStatus(object sender, ProgressEventArgs e)
    {
        SetStatus(e.Status);
    }

    private void SetStatus(string status)
    {
        label1.Text = status;
    }

    private void button1_Click_1(object sender, EventArgs e)
    {
         TestClass.Func();
    }

}

public class TestClass
{
    public delegate void StatusUpdateHandler(object sender, ProgressEventArgs e);
    public event StatusUpdateHandler OnUpdateStatus;

    public static void Func()
    {
        //time consuming code
        UpdateStatus(status);
        // time consuming code
        UpdateStatus(status);
    }

    private void UpdateStatus(string status)
    {
        // Make sure someone is listening to event
        if (OnUpdateStatus == null) return;

        ProgressEventArgs args = new ProgressEventArgs(status);
        OnUpdateStatus(this, args);
    }
}

public class ProgressEventArgs : EventArgs
{
    public string Status { get; private set; }

    public ProgressEventArgs(string status)
    {
        Status = status;
    }
}

No, abstract class can never be instantiated.

Try the event delegation method, this works in almost all cases.

$(document.body).on('change',"#selectID",function (e) {
   //doStuff
   var optVal= $("#selectID option:selected").val();
});

You can easily subtract with calendar with SimpleDateFormat

 public static String subtractDate(String time,int subtractDay) throws ParseException {


        Calendar cal = Calendar.getInstance();
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm", Locale.ENGLISH);
        cal.setTime(sdf.parse(time));
        cal.add(Calendar.DATE,-subtractDay);
        String wantedDate = sdf.format(cal.getTime());

        Log.d("tag",wantedDate);
        return wantedDate;

    }

After going mad trying to remove the border in IE7, I found that the frameBorder attribute is case sensitive.

You have to set the frameBorder attribute with a capital B.

<iframe frameBorder="0"></iframe>

It seems that there is a typo, since 1104*1104*50=60940800 and you are trying to reshape to dimensions 50,1104,104. So it seems that you need to change 104 to 1104.

You declare a function pointer variable for the given signature of your functions like this:

bool (* fnptr)();

you can assign it one of your functions:

fnptr = A;

and you can call it:

bool result = fnptr();

You might consider using typedefs to define a type for every distinct function signature you need. This will make the code easier to read and to maintain. i.e. for the signature of functions returning bool with no arguments this could be:

typdef bool (* BoolFn)();

and then you can use like this to declare the function pointer variable for this type:

BoolFn fnptr;
