class Node: 
    rChild,lChild,data = None,None,None

This is wrong - it makes your variables class variables - that is, every instance of Node uses the same values (changing rChild of any node changes it for all nodes!). This is clearly not what you want; try

class Node: 
    def __init__(self, key):
        self.rChild = None
        self.lChild = None
        self.data = key

now each node has its own set of variables. The same applies to your definition of Tree,

class Tree:
    root,size = None,0    # <- lose this line!
    def __init__(self):
        self.root = None
        self.size = 0

Further, each class should be a "new-style" class derived from the "object" class and should chain back to object.__init__():

class Node(object): 
    def __init__(self, data, rChild=None, lChild=None):
        super(Node,self).__init__()
        self.data   = data
        self.rChild = rChild
        self.lChild = lChild

class Tree(object):
    def __init__(self):
        super(Tree,self).__init__()
        self.root = None
        self.size = 0

Also, main() is indented too far - as shown, it is a method of Tree which is uncallable because it does not accept a self argument.

Also, you are modifying the object's data directly (t.root = Node(4)) which kind of destroys encapsulation (the whole point of having classes in the first place); you should be doing something more like

def main():
    t = Tree()
    t.add(4)    # <- let the tree create a data Node and insert it
    t.add(5)

• Binary search tree: when inorder traversal is made on binary tree, you get sorted values of inserted items
• Binary tree: no sorted order is found in any kind of traversal

Heap just guarantees that elements on higher levels are greater (for max-heap) or smaller (for min-heap) than elements on lower levels

I love the above answer and putting my comment just more specific to my need and usage. I had to get the n locations list find the distance from each location to specific point say (0,0) and then return the a m locations having smaller distance. I used Priority Queue which is Heap. For finding distances and putting in heap it took me n(log(n)) n-locations log(n) each insertion. Then for getting m with shortest distances it took m(log(n)) m-locations log(n) deletions of heaping up.

I if would have to do this with BST, it would have taken me n(n) worst case insertion.(Say the first value is very smaller and all other comes sequentially longer and longer and the tree spans to right child only or left child in case of smaller and smaller. The min would have taken O(1) time but again I had to balance. So from my situation and all above answers what I got is when you are only after the values at min or max priority basis go for heap.

int maxDepth(BinaryTreeNode root) {
    if(root == null || (root.left == null && root.right == null)) {
       return 0;
    }

    return 1 + Math.max(maxDepth(root.left), maxDepth(root.right));
}

Its a good programming practice to avoid having null values in a Map.

If you have an entry with null value, then it is not possible to tell whether an entry is present in the map or has a null value associated with it.

You can either define a constant for such cases (Example: String NOT_VALID = "#NA"), or you can have another collection storing keys which have null values.

Please check this link for more details.

An easy way to see all the properties on a particular DOM node in Chrome (I'm on v.69) is to right click on the element, select inspect, and then instead of viewing the "Style" tab click on "Properties".

Inside of the Properties tab you will see all the properties for your particular element.

There are two easy ways, depending on if you want to deal with exceptions or get a default value.

You can use the First<T>() or the FirstOrDefault<T>() extension method to get the first result or default(T).

var list = new List<int> { 1, 2, 4 };
var result = list.Where(i => i == 3).First(); // throws InvalidOperationException
var result = list.Where(i => i == 3).FirstOrDefault(); // = 0

To fetch only one distinct record from duplicate column of two rows you can use "rowid" column which is maintained by oracle itself as Primary key,so first try

"select rowid,RequestID,CreatedDate,HistoryStatus  from temptable;"

and then you can fetch second row only by it's value of 'rowid' column by using in SELECT statement.

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

Mockito returns objects but static means "class level,not object level"So mockito will give null pointer exception for static.

I just thought I'd link this here as the article has most of the answer you're looking for and it's also very interesting

http://www.kalzumeus.com/2011/11/17/i-saw-an-extremely-subtle-bug-today-and-i-just-have-to-tell-someone/

The answer is: you can't only through sms, i have tried that approach before.

You could fetch the base station IDs, but this won't help you a lot without the location of the base station itself and this informations are really hard to retrieve from the providers.

I have looked through the 3 apps you have listed in your question:

1. The App uses WiFi and GPRS location service, quite the same approach as Google uses on the phone. phonesavvy maybe has a base station location database or uses a database retrieved e.g. from OpenStreetMap or some similar crowd-based project.
2. The app analyzes just the number for country code and city code. No location there.
3. Dito.

Use " instead of " to escape it.

web.config is an XML file so you should use XML escaping.

connectionString="Server=dbsrv;User ID=myDbUser;Password=somepass"word"

See this forum thread.

Update:

" should work, but as it doesn't, have you tried some of the other string escape sequences for .NET? \" and ""?

Update 2:

Try single quotes for the connectionString:

connectionString='Server=dbsrv;User ID=myDbUser;Password=somepass"word'

Or:

connectionString='Server=dbsrv;User ID=myDbUser;Password=somepass"word'

Update 3:

From MSDN (SqlConnection.ConnectionString Property):

To include values that contain a semicolon, single-quote character, or double-quote character, the value must be enclosed in double quotation marks. If the value contains both a semicolon and a double-quote character, the value can be enclosed in single quotation marks.

So:

connectionString="Server=dbsrv;User ID=myDbUser;Password='somepass"word'"

The issue is not with web.config, but the format of the connection string. In a connection string, if you have a " in a value (of the key-value pair), you need to enclose the value in '. So, while Password=somepass"word does not work, Password='somepass"word' does.

Slightly modified from: Python Pandas Dataframe: Normalize data between 0.01 and 0.99? but from some of the comments thought it was relevant (sorry if considered a repost though...)

I wanted customized normalization in that regular percentile of datum or z-score was not adequate. Sometimes I knew what the feasible max and min of the population were, and therefore wanted to define it other than my sample, or a different midpoint, or whatever! This can often be useful for rescaling and normalizing data for neural nets where you may want all inputs between 0 and 1, but some of your data may need to be scaled in a more customized way... because percentiles and stdevs assumes your sample covers the population, but sometimes we know this isn't true. It was also very useful for me when visualizing data in heatmaps. So i built a custom function (used extra steps in the code here to make it as readable as possible):

def NormData(s,low='min',center='mid',hi='max',insideout=False,shrinkfactor=0.):    
    if low=='min':
        low=min(s)
    elif low=='abs':
        low=max(abs(min(s)),abs(max(s)))*-1.#sign(min(s))
    if hi=='max':
        hi=max(s)
    elif hi=='abs':
        hi=max(abs(min(s)),abs(max(s)))*1.#sign(max(s))

    if center=='mid':
        center=(max(s)+min(s))/2
    elif center=='avg':
        center=mean(s)
    elif center=='median':
        center=median(s)

    s2=[x-center for x in s]
    hi=hi-center
    low=low-center
    center=0.

    r=[]

    for x in s2:
        if x<low:
            r.append(0.)
        elif x>hi:
            r.append(1.)
        else:
            if x>=center:
                r.append((x-center)/(hi-center)*0.5+0.5)
            else:
                r.append((x-low)/(center-low)*0.5+0.)

    if insideout==True:
        ir=[(1.-abs(z-0.5)*2.) for z in r]
        r=ir

    rr =[x-(x-0.5)*shrinkfactor for x in r]    
    return rr

This will take in a pandas series, or even just a list and normalize it to your specified low, center, and high points. also there is a shrink factor! to allow you to scale down the data away from endpoints 0 and 1 (I had to do this when combining colormaps in matplotlib:Single pcolormesh with more than one colormap using Matplotlib) So you can likely see how the code works, but basically say you have values [-5,1,10] in a sample, but want to normalize based on a range of -7 to 7 (so anything above 7, our "10" is treated as a 7 effectively) with a midpoint of 2, but shrink it to fit a 256 RGB colormap:

#In[1]
NormData([-5,2,10],low=-7,center=1,hi=7,shrinkfactor=2./256)
#Out[1]
[0.1279296875, 0.5826822916666667, 0.99609375]

It can also turn your data inside out... this may seem odd, but I found it useful for heatmapping. Say you want a darker color for values closer to 0 rather than hi/low. You could heatmap based on normalized data where insideout=True:

#In[2]
NormData([-5,2,10],low=-7,center=1,hi=7,insideout=True,shrinkfactor=2./256)
#Out[2]
[0.251953125, 0.8307291666666666, 0.00390625]

So now "2" which is closest to the center, defined as "1" is the highest value.

Anyways, I thought my application was relevant if you're looking to rescale data in other ways that could have useful applications to you.

If you are on a OS X, this probably has nothing to do with the sed command. On the OSX version of sed, the -i option expects an extension argument so your command is actually parsed as the extension argument and the file path is interpreted as the command code.

Try adding the -e argument explicitly and giving '' as argument to -i:

find ./ -type f -exec sed -i '' -e "s/192.168.20.1/new.domain.com/" {} \;

See this.

Presence of int k; in the header file causes symbol k to be defined within each translation unit this header is included to while linker expects it to be defined only once (aka One Definition Rule Violation).

While suggestion involving extern are not wrong, extern is a C-ism and should not be used.

Pre C++17 solution that would allow variable in header file to be defined in multiple translation units without causing ODR violation would be conversion to template:

template<typename x_Dummy = void> class
t_HeaderVariableHolder
{
    public: static int s_k;
};

template<typename x_Dummy> int t_HeaderVariableHolder<x_Dummy>::s_k{};

// Getter is necessary to decouple variable storage implementation details from access to it.
inline int & Get_K() noexcept
{
    return t_HeaderVariableHolder<>::s_k;
}

With C++17 things become much simpler as it allows inline variables:

inline int g_k{};

// Getter is necessary to decouple variable storage implementation details from access to it.
inline int & Get_K() noexcept
{
    return g_k;
}

Did you update the project (right-click on the project, "Maven" > "Update project...")? Otherwise, you need to check if pom.xml contains the necessary slf4j dependencies, e.g.:

    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>jcl-over-slf4j</artifactId>
        <version>1.7.0</version>
        <scope>runtime</scope>
    </dependency>
    <dependency>

This error happens very rarely on my Windows machine. I ended up rebooting the machine, and the error went away.

As others have already pointed out, the date and time formats of %DATE% and %TIME% (as well as date /T and time /T) are locale-dependent, so extracting the current date and time is always a nightmare, and it is impossible to get a solution that works with all possible formats since there are hardly any format limitations.

But there is another problem with a code like the following one (let us assume a date format like MM/DD/YYYY and a 12 h time format like h:mm:ss.ff ap where ap is either AM or PM and ff are fractional seconds):

rem // Resolve AM/PM time:
set "HOUR=%TIME:~,2%"
if "%TIME:~-2%" == "PM" if %HOUR% lss 12 set /A "HOUR+=12"
if "%TIME:~-2%" == "AM" if %HOUR% equ 12 set /A "HOUR-=12"
rem // Left-zero-pad hour:
set "HOUR=0%HOUR%"
rem // Build and display date/time string:
echo %DATE:~-4,4%%DATE:~0,2%%DATE:~3,2%_%HOUR:~-2%%TIME:~3,2%%TIME:~6,2%

Each instance of %DATE% and %TIME% returns the date or time value present at the time of its expansion, therefore the first %DATE% or %TIME% expression might return a different value than the following ones (you can prove that when echoing a long string containing a huge amount of such, preferrably %TIME%, expressions).

You could improve the aforementioned code to hold a single instance of %DATE% and %TIME% like this:

rem // Store current date and time once in the same line:
set "CURRDATE=%DATE%" & set "CURRTIME=%TIME%"
rem // Resolve AM/PM time:
set "HOUR=%CURRTIME:~,2%"
if "%CURRTIME:~-2%" == "PM" if %HOUR% lss 12 set /A "HOUR+=12"
if "%CURRTIME:~-2%" == "AM" if %HOUR% equ 12 set /A "HOUR-=12"
rem // Left-zero-pad hour:
set "HOUR=0%HOUR%"
rem // Build and display date/time string:
echo %CURRDATE:~-4,4%%CURRDATE:~0,2%%CURRDATE:~3,2%_%HOUR:~-2%%CURRTIME:~3,2%%CURRTIME:~6,2%

But still, the returned values in %DATE% and %TIME% could reflect different days when executed at midnight.

The only way to have the same day in %CURRDATE% and %CURRTIME% is this:

rem // Store current date and time once in the same line:
set "CURRDATE=%DATE%" & set "CURRTIME=%TIME%"
rem // Resolve AM/PM time:
set "HOUR=%CURRTIME:~,2%"
if "%CURRTIME:~-2%" == "PM" if %HOUR% lss 12 set /A "HOUR+=12"
if "%CURRTIME:~-2%" == "AM" if %HOUR% equ 12 set /A "HOUR-=12"
rem // Fix date/time midnight discrepancy:
if not "%CURRDATE%" == "%DATE%" if %CURRTIME:~0,2% equ 0 set "CURRDATE=%DATE%"
rem // Left-zero-pad hour:
set "HOUR=0%HOUR%"
rem // Build and display date/time string:
echo %CURRDATE:~-4,4%%CURRDATE:~0,2%%CURRDATE:~3,2%_%HOUR:~-2%%CURRTIME:~3,2%%CURRTIME:~6,2%

Of course the occurrence of the described problem is quite improbable, but at one point it will happen and cause strange unexplainable failures.

The described problem cannot occur with the approaches based on the wmic command as described in the answer by user Stephan and in the answer by user PA., so I strongly recommend to go for one of them. The only disadvantage of wmic is that it is way slower.

As of today (Feb 27), there is a new For-Each toolbox on the MATLAB File Exchange that accomplishes the concept of foreach. foreach is not a part of the MATLAB language but use of this toolbox gives us the ability to emulate what foreach would do.

2020 edit

Use URLSearchParams, as this job no longer requires any kind of custom code. Browsers can do this for you with a single constructor:

const str = "1111342=Adam%20Franco&348572=Bob%20Jones";
const data = new URLSearchParams(str);
for (pair of data) console.log(pair)

yields

Array [ "1111342", "Adam Franco" ]
Array [ "348572", "Bob Jones" ]

So there is no reason to use regex for this anymore.

Original answer

If you don't want to rely on the "blind matching" that comes with running exec style matching, JavaScript does come with match-all functionality built in, but it's part of the replace function call, when using a "what to do with the capture groups" handling function:

var data = {};

var getKeyValue = function(fullPattern, group1, group2, group3) {
  data[group2] = group3;
};

mystring.replace(/(?:&|&)?([^=]+)=([^&]+)/g, getKeyValue);

done.

Instead of using the capture group handling function to actually return replacement strings (for replace handling, the first arg is the full pattern match, and subsequent args are individual capture groups) we simply take the groups 2 and 3 captures, and cache that pair.

So, rather than writing complicated parsing functions, remember that the "matchAll" function in JavaScript is simply "replace" with a replacement handler function, and much pattern matching efficiency can be had.

Just use awk, it's much simpler than grep in letting you clearly express compound conditions.

If you want to skip lines that contains both loom and gloom:

awk '/loom/ && !/gloom/{ print FILENAME, FNR, $0 }' ~/projects/**/trunk/src/**/*.@(h|cpp)

or if you want to print them:

awk '/(^|[^g])loom/{ print FILENAME, FNR, $0 }' ~/projects/**/trunk/src/**/*.@(h|cpp)

and if the reality is you just want lines where loom appears as a word by itself:

awk '/\<loom\>/{ print FILENAME, FNR, $0 }' ~/projects/**/trunk/src/**/*.@(h|cpp)

mysql -u user -h 192.168.1.2 -p

This should be enough for connection to MySQL server. Please, check the firewall of 192.168.1.2 if remote connection to MySQL server is enabled.

EDIT 2

• For all object changes that need reactivity use Vue.set(object, prop, value)
• For array mutations, you can look at the currently supported list here

EDIT 1

For vuex you will want to do Vue.set(state.object, key, value)

Original

So just for others who come to this question. It appears at some point in Vue 2.* they removed this.items.$set(index, val) in favor of this.$set(this.items, index, val).

Splice is still available and here is a link to array mutation methods available in vue link.

Axios

An example (axios_example.js) using Axios in Node.js:

const axios = require('axios');
const express = require('express');
const app = express();
const port = process.env.PORT || 5000;

app.get('/search', function(req, res) {
    let query = req.query.queryStr;
    let url = `https://your.service.org?query=${query}`;

    axios({
        method:'get',
        url,
        auth: {
            username: 'the_username',
            password: 'the_password'
        }
    })
    .then(function (response) {
        res.send(JSON.stringify(response.data));
    })
    .catch(function (error) {
        console.log(error);
    });
});

var server = app.listen(port);

Be sure in your project directory you do:

npm init
npm install express
npm install axios
node axios_example.js

You can then test the Node.js REST API using your browser at: http://localhost:5000/search?queryStr=xxxxxxxxx

Similarly you can do post, such as:

axios({
  method: 'post',
  url: 'https://your.service.org/user/12345',
  data: {
    firstName: 'Fred',
    lastName: 'Flintstone'
  }
});

SuperAgent

Similarly you can use SuperAgent.

superagent.get('https://your.service.org?query=xxxx')
.end((err, response) => {
    if (err) { return console.log(err); }
    res.send(JSON.stringify(response.body));
});

And if you want to do basic authentication:

superagent.get('https://your.service.org?query=xxxx')
.auth('the_username', 'the_password')
.end((err, response) => {
    if (err) { return console.log(err); }
    res.send(JSON.stringify(response.body));
});

You need the extended permission "read_stream", then you need to call the Facebook API endpoint, and add likes,shares to your fields.

This call

https://developers.facebook.com/tools/explorer?method=GET&path=me/feed?fields=likes,shares

will return a data array like this

{
   "data": [
    {
     "likes": {
        "data": [
                 {
                   "name": "name of user who liked status ",
                   "id": "id of user who liked status "
                 }
                ],
        "count": number of likes
     },
     "shares": {
      "count": number of shares 
     }, 
     "id": "post id",
     "created_time": "post creation time"
    }
   ]
}

this is for classes

$('.nameofdiv').val('we are developers');

for ids

$('#nameofdiv').val('we are developers');

now if u have an iput in a form u can use

$("#form li.name input.name_val").val('we are awsome developers');

I just wrote a quick plugin to run a test using your same snippet and it works fine

$.fn.test = function() {
      return this.each(function(){
        var new_id = 5;
        $(this).attr('id',   this.id + '_' + new_id);
        $(this).attr('name', this.name + '_' + new_id);
        $(this).attr('value', 'test');
      });
    };

$(document).ready(function() {
    $('#field_id').test()
});

<body>
  <div id="container">

  <input type="text" name="field_name" id="field_id" value="meh" />
  </div>
</body>

So I can only presume something else is going on in your code. Can you provide some more details?

if you have an OLD backup and is in a hurry:

make a NEW BACKUP of your current, git-broken, project path.

1. move your .git to trash (never delete)
2. copy .git from the OLD backup
3. git pull (will create merge conflicts)
4. move all your sources (everything you put in git) to trash: ./src (never delete)
5. .copy all your sources (everything you put in git) from the NEW BACKUP
6. accept all "merges" at git gui, push and... clap your hands!

PHP 7.2 + MySQL/Mariadb

MySQL will send you multiple fields with the same name. Even in the terminal client. But if you want an associative array, you'll have to make the keys yourself.

Thanks to @axelbrz for the original. I've ported it to newer php and cleaned it up a little:

function mysqli_rows_with_columns($link, $query) {
    $result = mysqli_query($link, $query);
    if (!$result) {
        return mysqli_error($link);
    }
    $field_count = mysqli_num_fields($result);
    $fields = array();
    for ($i = 0; $i < $field_count; $i++) {
        $field = mysqli_fetch_field_direct($result, $i);
        $fields[] = $field->table . '.' . $field->name; # changed by AS
        #$fields[] = $field->orgtable . '.' . $field->orgname; # actual table/field names
    }
    $rows = array();
    while ($row = mysqli_fetch_row($result)) {
        $new_row = array();
        for ($i = 0; $i < $field_count; $i++) {
            $new_row[$fields[$i]] = $row[$i];
        }
        $rows[] = $new_row;
    }
    mysqli_free_result($result);
    return $rows;
}

$link = mysqli_connect('localhost', 'fixme', 'fixme', 'fixme');
print_r(mysqli_rows_with_columns($link, 'select foo.*, bar.* from foo, bar'));

Superkey

A superkey is a combination of attributes that can be uniquely used to identify a 
database record. A table might have many superkeys.Candidate keys are a special subset
of superkeys that do not have any extraneous information in them.

Examples: Imagine a table with the fields <Name>, <Age>, <SSN> and <Phone Extension>.
This table has many possible superkeys. Three of these are <SSN>, <Phone Extension, Name>
and <SSN, Name>.Of those listed, only <SSN> is a **candidate key**, as the others
contain information not necessary to uniquely identify records.

As many have already stated, as much as you want to test the private methods you shouldn't hack your code or transpiler to make it work for you. Modern day TypeScript will deny most all of the hacks that people have provided so far.

Solution

TLDR; if a method should be tested then you should be decoupling the code into a class that you can expose the method to be public to be tested.

The reason you have the method private is because the functionality doesn't necessarily belong to be exposed by that class, and therefore if the functionality doesn't belong there it should be decoupled into it's own class.

Example

I ran across this article that does a great job of explaining how you should tackle testing private methods. It even covers some of the methods here and how why they're bad implementations.

        format.ToString();

It is possible to use std::regex .

Depending on the size of your file and the memory available to you , it is possible read it either line by line or entirely in an std::string.

To read the file one can use :

std::ifstream t("file.txt");
std::string sin((std::istreambuf_iterator<char>(t)),
                 std::istreambuf_iterator<char>());

then you can match with this which is actually customizable to your needs.

std::regex word_regex(",\\s]+");
auto what = 
    std::sregex_iterator(sin.begin(), sin.end(), word_regex);
auto wend = std::sregex_iterator();

std::vector<std::string> v;
for (;what!=wend ; wend) {
    std::smatch match = *what;
    v.push_back(match.str());
}

In Python, you can't just embed arbitrary Python expressions into literal strings and have it substitute the value of the string. You need to either:

sys.stderr.write("Usage: " + sys.argv[0])

or

sys.stderr.write("Usage: %s" % sys.argv[0])

Also, you may want to consider using the following syntax of print (for Python earlier than 3.x):

print >>sys.stderr, "Usage:", sys.argv[0]

Using print arguably makes the code easier to read. Python automatically adds a space between arguments to the print statement, so there will be one space after the colon in the above example.

In Python 3.x, you would use the print function:

print("Usage:", sys.argv[0], file=sys.stderr)

Finally, in Python 2.6 and later you can use .format:

print >>sys.stderr, "Usage: {0}".format(sys.argv[0])

Try to use TranslateAnimation class, which creates the animation for position changes. Try reading this for help - http://developer.android.com/reference/android/view/animation/TranslateAnimation.html

Update: Here's the example for this. If you have the height of your view as 50 and in the hide mode you want to show only 10 px. The sample code would be -

TranslateAnimation anim=new TranslateAnimation(0,0,-40,0);
anim.setFillAfter(true);
view.setAnimation(anim);

PS: There are lot's or other methods there to help you use the animation according to your need. Also have a look at the RelativeLayout.LayoutParams if you want to completely customize the code, however using the TranslateAnimation is easier to use.

EDIT:-Complex version using LayoutParams

RelativeLayout relParam=new RelativeLayout.LayoutParam(RelativeLayout.LayoutParam.FILL_PARENT,RelativeLayout.LayoutParam.WRAP_CONTENT); //you can give hard coded width and height here in (width,height) format.
relParam.topMargin=-50; //any number that work.Set it to 0, when you want to show it.
view.setLayoutParams(relparam);

This example code assumes you are putting your view in RelativeLayout, if not change the name of Layout, however other layout might not work. If you want to give an animation effect on them, reduce or increase the topMargin slowly. You can consider using Thread.sleep() there too.

If you are looking specifically for memory in JVM:

Runtime runtime = Runtime.getRuntime();

NumberFormat format = NumberFormat.getInstance();

StringBuilder sb = new StringBuilder();
long maxMemory = runtime.maxMemory();
long allocatedMemory = runtime.totalMemory();
long freeMemory = runtime.freeMemory();

sb.append("free memory: " + format.format(freeMemory / 1024) + "<br/>");
sb.append("allocated memory: " + format.format(allocatedMemory / 1024) + "<br/>");
sb.append("max memory: " + format.format(maxMemory / 1024) + "<br/>");
sb.append("total free memory: " + format.format((freeMemory + (maxMemory - allocatedMemory)) / 1024) + "<br/>");

However, these should be taken only as an estimate...

It depends on what exactly you want to achieve.

If you just want to have it on the right, then I'd recommend against using position absolute, because it opens a whole can of worms down the line.

The HTML can also be unchanged:

HTML

<div>
    <h1> Ok </h1>
    <button type='button'>Button</button>
</div>

the CSS then should be something along the lines of:

CSS

div {
    background: purple;
    overflow: hidden;
}

div h1 {
    text-align: center;
    display: inline-block;
    width: 100%;
    margin-right: -50%;
}

div button {
    float: right;
}

You can see it in action here: http://jsfiddle.net/azhH5/

If you can change the HTML, then it gets a bit simpler:

HTML

<div>
    <button type='button'>Button</button>
    <h1> Ok </h1>
</div>

CSS

div {
    background: purple;
    overflow: hidden;
}

div h1 {
    text-align: center;
}

div button {
    float: right;
    margin-left: -50%;
}

You can see it in action: http://jsfiddle.net/8WA3k/1/

If you want to have the button on the same line as the Text, you can achieve it by doing this:

HTML

<div>
    <button type='button'>Button</button>
    <h1> Ok </h1>
</div>

CSS

div {
    background: purple;
    overflow: hidden;
}

div h1 {
    text-align: center;
}

div button {
    float: right;
    margin-left: -50%;
    margin-top: 2em;
}

You an see that in action here: http://jsfiddle.net/EtqVh/1/

Cleary in the lest example you'd have to adjust the margin-top for the specified font-size of the <h1>

EDIT:

As you can see, it doesn't get popped out of the <div>, it's till inside. this is achieved by two things: the negative margin on the <button>, and the overflow: hidden; on the <div>

EDIT 2:

I just saw that you also want it to be a bit away from the margin on the right. That's easily achievable with this method. Just add margin-right: 1em; to the <button>, like this:

div {
    background: purple;
    overflow: hidden;
}

div h1 {
    text-align: center;
}

div button {
    float: right;
    margin-left: -50%;
    margin-top: 2em;
    margin-right: 1em;
}

You can see it in action here: http://jsfiddle.net/QkvGb/

For a similar situation I used this PKCS #5: Password-Based Cryptography Standard from RSA laboratories. You can avoid storing password, by substituting it with something that can be generated only from the password (in one sentence). There are some JavaScript implementations.

I know this thread is old, but figured I would throw in what came up with since I just ran into this same issue. It may not be efficient, but I believe it gets the job done.

SELECT TOP 10 p.id, pl.nm, pl.val, pl.txt_val
INTO #yourTempTable
from dm.labs pl 
join mas_data.patients p on pl.id = p.id   
where pl.nm like '%LDL%' and val is not null

select p.id, pl.nm, pl.val, pl.txt_val
from #yourTempTable
where id IN (select distinct id from #yourTempTable)

Just sharing what worked for me:

git clone --recurse-submodules <repository path>

This clones the remote repository already including the submodules. This means you won't need to run git submodule update or init after cloning.

Strange that so much answers/votes, but no one add the following code as an answer:

using (var opnDlg = new OpenFileDialog()) //ANY dialog
{ 
    //opnDlg.Filter = "Png Files (*.png)|*.png";
    //opnDlg.Filter = "Excel Files (*.xls, *.xlsx)|*.xls;*.xlsx|CSV Files (*.csv)|*.csv"

    if (opnDlg.ShowDialog() == DialogResult.OK)
    {
        //opnDlg.SelectedPath -- your result
    }
}

\xe2 is the '-' character, it appears in some copy and paste it uses a different equal looking '-' that causes encoding errors. Replace the '-'(from copy paste) with the correct '-' (from you keyboard button).

The shortest implementation for capitalizing words within a string is the following using ES6's arrow functions:

'your string'.replace(/\b\w/g, l => l.toUpperCase())
// => 'Your String'

ES5 compatible implementation:

'your string'.replace(/\b\w/g, function(l){ return l.toUpperCase() })
// => 'Your String'

The regex basically matches the first letter of each word within the given string and transforms only that letter to uppercase:

• \b matches a word boundary (the beginning or ending of word);
• \w matches the following meta-character [a-zA-Z0-9].

For non-ASCII characters refer to this solution instead

'ÿöur striñg'.replace(/(^|\s)\S/g, l => l.toUpperCase())

This regex matches the first letter and every non-whitespace letter preceded by whitespace within the given string and transforms only that letter to uppercase:

• \s matches a whitespace character
• \S matches a non-whitespace character
• (x|y) matches any of the specified alternatives

A non-capturing group could have been used here as follows /(?:^|\s)\S/g though the g flag within our regex wont capture sub-groups by design anyway.

Cheers!

If your issue is like mine, then this a workaround. The good news is that you wont have to delete your db.

Check that there isn't some other model that uses this model as a reference.

django.db.utils.OperationalError: no such column: parts_part_type.blah

This was only happening to me because I had another model called "product" in a different app called "products" that referenced this model.

part = models.ForeignKey("parts.Part", related_name="some part", limit_choices_to={'part_type':Part_Type.objects.get(prefix='PART')},)

My solution was:

1. comment out the other app (in this case prodcuts) from settings.py
2. python manage.py makemigrations; python manage.py migrate
3. un-comment the other app so its enabled again.
4. python manage.py makemigrations; python manage.py migrate

Technically I think I need to change the limit_choices_to reference so

Try the Parse method.

I do not know about React, but in the general case you can pass custom attributes like this:

1) define inside an html-tag a new attribute with data- prefix

data-mydatafield = "asdasdasdaad"

2) get from javascript with

e.target.attributes.getNamedItem("data-mydatafield").value 

I had this problem on Ubuntu 18.04. I updated the gem

sudo gem install rails
sudo gem install jekyll
sudo gem install jekyll bundler
cd ~/desiredFolder
jekyll new <foldername>
cd <foldername> OR 
bundle init
bundle install
bundle add jekyll
bundle exec jekyll serve

All worked and goto your browser just go to http://127.0.0.1:4000/ and it really should be running

The short answer: no.

The long answer:

Fixed formats work better for HTML emails. In my experience you're best off pretending it's 1999 when it comes to HTML emails. Be explicit and use HTML attributes (width="650") where ever possible in your table definitions, not CSS (style="width:650px"). Use fixed widths, no percentages. A table width of 650 pixels wide is a safe bet. Use inline CSS to set text properties.

It's not a matter of what works in "HTML emails", but rather the plethora of email clients and their limited (and sometimes deliberately so in the case of Gmail, Hotmail etc) ability to render HTML.

I used pdf unite on the linux terminal by leveraging subprocess (assumes one.pdf and two.pdf exist on the directory) and the aim is to merge them to three.pdf

 import subprocess
 subprocess.call(['pdfunite one.pdf two.pdf three.pdf'],shell=True)

The answer by @AKX works on the command line, but not within a batch file. Within a batch file, you need an extra %, like this:

@echo off
for /R TutorialSteps %%F in (*.py) do echo %%~nF

You can also try using multiprocessing.Process with daemon=True; the process.start() method does not block and you can return a response/status immediately to the caller while your expensive function executes in the background.

I experienced similar problem while working with falcon framework and using daemon process helped.

You'd need to do the following:

from multiprocessing import Process

@app.route('/render/<id>', methods=['POST'])
def render_script(id=None):
    ...
    heavy_process = Process(  # Create a daemonic process with heavy "my_func"
        target=my_func,
        daemon=True
    )
    heavy_process.start()
    return Response(
        mimetype='application/json',
        status=200
    )

# Define some heavy function
def my_func():
    time.sleep(10)
    print("Process finished")

You should get a response immediately and, after 10s you should see a printed message in the console.

NOTE: Keep in mind that daemonic processes are not allowed to spawn any child processes.

• Make a copy of your OpenSSL config in your home directory:

  cp /System/Library/OpenSSL/openssl.cnf ~/openssl-temp.cnf
  

  or on Linux:

  cp /etc/ssl/openssl.cnf ~/openssl-temp.cnf
  

• Add Subject Alternative Name to openssl-temp.cnf, under [v3_ca]:

  [ v3_ca ]
  subjectAltName = DNS:localhost
  

  Replace localhost by the domain for which you want to generate that certificate.

• Generate certificate:

  sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 \
      -config ~/openssl-temp.cnf
      -keyout /path/to/your.key -out /path/to/your.crt
  

You can then delete openssl-temp.cnf

Restart Android Studio Worked in my case

In Mac it is Alt+Command+L(assuming you haven't changed any of your modifier keys or Intellij keyboard shortcuts from it's default state)

Seems pretty straightforward, according to the docs on the page you linked (emphasis mine).

requests.get(url, params=None, headers=None, cookies=None, auth=None, timeout=None)

Sends a GET request. Returns Response object.

Parameters:

• url – URL for the new Request object.
• params – (optional) Dictionary of GET Parameters to send with the Request.
• headers – (optional) Dictionary of HTTP Headers to send with the Request.
• cookies – (optional) CookieJar object to send with the Request.
• auth – (optional) AuthObject to enable Basic HTTP Auth.
• timeout – (optional) Float describing the timeout of the request.

If you have named tuples you can do this:

results = [t.age for t in mylist if t.person_id == 10]

Otherwise use indexes:

results = [t[1] for t in mylist if t[0] == 10]

Or use tuple unpacking as per Nate's answer. Note that you don't have to give a meaningful name to every item you unpack. You can do (person_id, age, _, _, _, _) to unpack a six item tuple.

The lexically scoped integer pragma forces Perl to use integer arithmetic in its scope:

print 3.0/2.1 . "\n";    # => 1.42857142857143
{
  use integer;
  print 3.0/2.1 . "\n";  # => 1
}
print 3.0/2.1 . "\n";    # => 1.42857142857143

where date_dt = to_date(to_char(sysdate-1, 'YYYY-MM-DD') || ' 19:16:08', 'YYYY-MM-DD HH24:MI:SS') 

should work.

This solution unlock me after couple of hours of research :

In the configuration initialize the core() option

@Override
public void configure(HttpSecurity http) throws Exception {
http
    .cors()
    .and()
    .etc
}

Initialize your Credential, Origin, Header and Method as your wish in the corsFilter.

@Bean
public CorsFilter corsFilter() {
  UrlBasedCorsConfigurationSource source = new 
  UrlBasedCorsConfigurationSource();
  CorsConfiguration config = new CorsConfiguration();
  config.setAllowCredentials(true);
  config.addAllowedOrigin("*");
  config.addAllowedHeader("*");
  config.addAllowedMethod("*");
  source.registerCorsConfiguration("/**", config);
  return new CorsFilter(source);
}

I didn't need to use this class:

@Bean
public CorsConfigurationSource corsConfigurationSource() {
}

You can use boost::lexical_cast:

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

int main( int argc, char* argv[] ){
std::string s1 = "10";
std::string s2 = "abc";
int i;

   try   {
      i = boost::lexical_cast<int>( s1 );
   }
   catch( boost::bad_lexical_cast & e ){
      std::cout << "Exception caught : " << e.what() << std::endl;
   }

   try   {
      i = boost::lexical_cast<int>( s2 );
   }
   catch( boost::bad_lexical_cast & e ){
      std::cout << "Exception caught : " << e.what() << std::endl;
   }

   return 0;
}

The easiest way to do so is using jQuery and animate.css animation library.

Javascript

/* --- Show DIV --- */
$( '.example' ).removeClass( 'fadeOutRight' ).show().addClass( 'fadeInRight' );

/* --- Hide DIV --- */
$( '.example' ).removeClass( 'fadeInRight' ).addClass( 'fadeOutRight' );

HTML

<div class="example">Some text over here.</div>

Easy enough to implement. Just don't forget to include the animate.css file in the header :)

Here is a suggestion I have written that takes care of multiple input in your form.

This function gets the Object of the input field, put in your code

function fieldKeyup(obj){
    //  what you want this to do

} // fieldKeyup

This is the actual delayCall function, takes care of multiple input fields

function delayCall(obj,ms,fn){
    return $(obj).each(function(){
    if ( typeof this.timer == 'undefined' ) {
       // Define an array to keep track of all fields needed delays
       // This is in order to make this a multiple delay handling     
          function
        this.timer = new Array();
    }
    var obj = this;
    if (this.timer[obj.id]){
        clearTimeout(this.timer[obj.id]);
        delete(this.timer[obj.id]);
    }

    this.timer[obj.id] = setTimeout(function(){
        fn(obj);}, ms);
    });
}; // delayCall

Usage:

$("#username").on("keyup",function(){
    delayCall($(this),500,fieldKeyup);
});

Prefix:

int a=0;

int b=++a;          // b=1,a=1 

before assignment the value of will be incremented.

Postfix:

int a=0;
int b=a++;  // a=1,b=0 

first assign the value of 'a' to 'b' then increment the value of 'a'

This is the Kotlin way:

In fragment_map.xml you should have:

<?xml version="1.0" encoding="utf-8"?>
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/map"
    android:name="com.google.android.gms.maps.SupportMapFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

In your MapFragment.kt you should have:

    private fun setupMap() {
        (childFragmentManager.findFragmentById(R.id.map) as SupportMapFragment?)!!.getMapAsync(this)
    }

Call setupMap() in onCreateView.

You can use the append function. For rows:

>>> from numpy import *
>>> a = array([10,20,30])
>>> append(a, [[1,2,3]], axis=0)
array([[10, 20, 30],      
       [1, 2, 3]])

For columns:

>>> append(a, [[15],[15]], axis=1)
array([[10, 20, 30, 15],      
       [1, 2, 3, 15]])

EDIT
Of course, as mentioned in other answers, unless you're doing some processing (ex. inversion) on the matrix/array EVERY time you append something to it, I would just create a list, append to it then convert it to an array.

You can separate out your business logic into a viewmodel, so your view has cleaner separation.

First create a viewmodel to store the Id the user will select along with a list of items that will appear in the DropDown.

ViewModel:

public class UserRoleViewModel
{
    // Display Attribute will appear in the Html.LabelFor
    [Display(Name = "User Role")]
    public int SelectedUserRoleId { get; set; }
    public IEnumerable<SelectListItem> UserRoles { get; set; }
}

References:

• DisplayAttribute

Inside the controller create a method to get your UserRole list and transform it into the form that will be presented in the view.

Controller:

private IEnumerable<SelectListItem> GetRoles()
{
    var dbUserRoles = new DbUserRoles();
    var roles = dbUserRoles
                .GetRoles()
                .Select(x =>
                        new SelectListItem
                            {
                                Value = x.UserRoleId.ToString(),
                                Text = x.UserRole
                            });

    return new SelectList(roles, "Value", "Text");
}

public ActionResult AddNewUser()
{
    var model = new UserRoleViewModel
                    {
                        UserRoles = GetRoles()
                    };
    return View(model);
}

References:

• SelectListItem
• SelectList Constructor (IEnumerable, String, String)

Now that the viewmodel is created the presentation logic is simplified

View:

@model UserRoleViewModel

@Html.LabelFor(m => m.SelectedUserRoleId)
@Html.DropDownListFor(m => m.SelectedUserRoleId, Model.UserRoles)

References:

• LabelExtensions.LabelFor
• SelectExtensions.DropDownListFor

This will produce:

<label for="SelectedUserRoleId">User Role</label>
<select id="SelectedUserRoleId" name="SelectedUserRoleId">
    <option value="1">First Role</option>
    <option value="2">Second Role</option>
    <option value="3">Etc...</option>
</select>

I generally use array split because it's easier simple syntax and scales better with more than 2 partitions.

import numpy as np
partitions = 2
dfs = np.array_split(df, partitions)

np.split(df, [100,200,300], axis=0] wants explicit index numbers which may or may not be desirable.

reinterpret_cast

The problem right now is that I'm running with -Werror

This is your real problem, IMO. You can try some automated ways of moving from (char *) to (const char *) but I would put money on them not just working. You will have to have a human involved for at least some of the work. For the short term, just ignore the warning (but IMO leave it on, or it'll never get fixed) and just remove the -Werror.

Include / Require you can include the same file more than once also:

require() is identical to include() except upon failure it will also produce a fatal E_COMPILE_ERROR level error. In other words, it will halt the script whereas include() only emits a warning (E_WARNING) which allows the script to continue.

require_once / include_once

is identical to include/require except PHP will check if the file has already been included, and if so, not include (require) it again.

I created a reusable Angular service to handle high quality resizing of images / canvases for anyone who's interested: https://gist.github.com/transitive-bullshit/37bac5e741eaec60e983

The service includes two solutions because they both have their own pros / cons. The lanczos convolution approach is higher quality at the cost of being slower, whereas the step-wise downscaling approach produces reasonably antialiased results and is significantly faster.

Example usage:

angular.module('demo').controller('ExampleCtrl', function (imageService) {
  // EXAMPLE USAGE
  // NOTE: it's bad practice to access the DOM inside a controller, 
  // but this is just to show the example usage.

  // resize by lanczos-sinc filter
  imageService.resize($('#myimg')[0], 256, 256)
    .then(function (resizedImage) {
      // do something with resized image
    })

  // resize by stepping down image size in increments of 2x
  imageService.resizeStep($('#myimg')[0], 256, 256)
    .then(function (resizedImage) {
      // do something with resized image
    })
})

If you are using BaseFragment for your app then you can add onBackPressedDispatcher to your base fragment.

//Make a BaseFragment for all your fragments
abstract class BaseFragment : Fragment() {

private lateinit var callback: OnBackPressedCallback

/**
 * SetBackButtonDispatcher in OnCreate
 */

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setBackButtonDispatcher()
}

/**
 * Adding BackButtonDispatcher callback to activity
 */
private fun setBackButtonDispatcher() {
    callback = object : OnBackPressedCallback(true) {
        override fun handleOnBackPressed() {
            onBackPressed()
        }
    }
    requireActivity().onBackPressedDispatcher.addCallback(this, callback)
}

/**
 * Override this method into your fragment to handleBackButton
 */
  open fun onBackPressed() {
  }

}

Override onBackPressed() in your fragment by extending basefragment

//How to use this into your fragment
class MyFragment() : BaseFragment(){

private lateinit var mView: View

override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View? {
    mView = inflater.inflate(R.layout.fragment_my, container, false)
    return mView.rootView
}

override fun onBackPressed() {
    //Write your code here on back pressed.
}

}

If you're using .NET 2.0, try XmlReader and its subclasses XmlTextReader, and XmlValidatingReader. They provide a fast, lightweight (memory usage, etc.), forward-only way to parse an XML file.

If you need XPath capabilities, try the XPathNavigator. If you need the entire document in memory try XmlDocument.

Or, once it's already in SSIS, you could create a derived column (as part of some data flow task) with:

(DT_I8)FLOOR((DT_R8)systemDateTime)

But you'd have to test to doublecheck.

If the Pod is part of a Deployment or Service, deleting it will restart the Pod and, potentially, place it onto another node:

$ kubectl delete po $POD_NAME

replace it if it's an individual Pod:

$ kubectl get po -n $namespace $POD_NAME -o yaml | kubectl replace -f -

You can always point to your home directory using ~ then you can refer to your data folder.

import pandas as pd
df = pd.read_csv("~/mydata/data.csv")

For your case, it should be like this

import pandas as pd
df = pd.read_csv("~/folder/folder2/data_folder/data.csv")

You can also set your data directory as a prefix

import pandas as pd
DATA_DIR = "~/folder/folder2/data_folder/"
df = pd.read_csv(DATA_DIR+"data.csv")

You can take advantage of f-strings as @nikos-tavoularis said

import pandas as pd
DATA_DIR = "~/folder/folder2/data_folder/"
FILE_NAME = "data.csv"
df = pd.read_csv(f"{DATA_DIR}{FILE_NAME}")

On Ubuntu 14.04 none of these suggestions worked. Postfix would override with the logged in system user as the sender. What worked was the following solution listed at this link --> Change outgoing mail address from root@servername - rackspace sendgrid postfix

STEPS:

1) Make sure this is set in /etc/postfix/main.cf:

   smtp_generic_maps = hash:/etc/postfix/generic

2) echo 'www-data [email protected]' >> /etc/postfix/generic

3) sudo postmap /etc/postfix/generic

4) sudo service postfix restart

The following will allow you to get at both the key and value at the same time.

foreach ($arr as $key => $value)
{
  echo($key);
}

I have (Open)JDK 8 and 11 installed on Windows 10 and I had the same problem. For me the following worked:

1. Set JAVA_HOME to point to JDK 8. (Mentioned in many answers before.) AND
2. Remove(!) JDK 11 from the PATH as it turned out that -- although displaying the JAVA_HOME path pointing to JDK 8 -- Cordova actually accessed JDK 11 that was included in the PATH, which made the Java version check fail.

use DateTime qw();
DateTime->now->strftime('%m/%d/%Y')   

expression returns 06/13/2012

This is valid YAML:

jobs:
 - name: A
   schedule: "0 0/5 * 1/1 * ? *"
   type: mongodb.cluster
   config:
     host: mongodb://localhost:27017/admin?replicaSet=rs
     minSecondaries: 2
     minOplogHours: 100
     maxSecondaryDelay: 120
 - name: B
   schedule: "0 0/5 * 1/1 * ? *"
   type: mongodb.cluster
   config:
     host: mongodb://localhost:27017/admin?replicaSet=rs
     minSecondaries: 2
     minOplogHours: 100
     maxSecondaryDelay: 120

Note, that every '-' starts new element in the sequence. Also, indentation of keys in the map should be exactly same.

java.net.URLDecoder deals only with the application/x-www-form-urlencoded MIME format (e.g. "%20" represents space), not with HTML character entities. I don't think there's anything on the Java platform for that. You could write your own utility class to do the conversion, like this one.

Simply show a new window with two buttons. Add property to contain user result.

This is equivalent to the path of the script:

%~dp0

This uses the batch parameter extension syntax. Parameter 0 is always the script itself.

If your script is stored at C:\example\script.bat, then %~dp0 evaluates to C:\example\.

ss64.com has more information about the parameter extension syntax. Here is the relevant excerpt:

You can get the value of any parameter using a % followed by it's numerical position on the command line.

[...]

When a parameter is used to supply a filename then the following extended syntax can be applied:

[...]

%~d1 Expand %1 to a Drive letter only - C:

[...]

%~p1 Expand %1 to a Path only e.g. \utils\ this includes a trailing \ which may be interpreted as an escape character by some commands.

[...]

The modifiers above can be combined:

%~dp1 Expand %1 to a drive letter and path only

[...]

You can get the pathname of the batch script itself with %0, parameter extensions can be applied to this so %~dp0 will return the Drive and Path to the batch script e.g. W:\scripts\

As far as I know there's no way to do a blanket delete of any cookie set on the domain. You can clear a cookie if you know the name and if the script is on the same domain as the cookie.

You can set the value to empty and the expiration date to somewhere in the past:

var mydate = new Date();
mydate.setTime(mydate.getTime() - 1);
document.cookie = "username=; expires=" + mydate.toGMTString(); 

There's an excellent article here on manipulating cookies using javascript.

Also you will specify route on action for set route

[HttpGet]
[Route("api/customers/")]
public List<Customer> Get()
{
   //gets all customer logic
}

[HttpGet]
[Route("api/customers/currentMonth")]
public List<Customer> GetCustomerByCurrentMonth()
{
     //gets some customer 
}

[HttpGet]
[Route("api/customers/{id}")]
public Customer GetCustomerById(string id)
{
  //gets a single customer by specified id
}
[HttpGet]
[Route("api/customers/customerByUsername/{username}")]
public Customer GetCustomerByUsername(string username)
{
    //gets customer by its username
}

I'm not sure what you mean by "then again by the parser". After the splitting has been done, there's no further traversal of the string, only a traversal of the list of split strings. This will probably actually be the fastest way to accomplish this, so long as the size of your string isn't absolutely huge. The fact that python uses immutable strings means that you must always create a new string, so this has to be done at some point anyway.

If your string is very large, the disadvantage is in memory usage: you'll have the original string and a list of split strings in memory at the same time, doubling the memory required. An iterator approach can save you this, building a string as needed, though it still pays the "splitting" penalty. However, if your string is that large, you generally want to avoid even the unsplit string being in memory. It would be better just to read the string from a file, which already allows you to iterate through it as lines.

However if you do have a huge string in memory already, one approach would be to use StringIO, which presents a file-like interface to a string, including allowing iterating by line (internally using .find to find the next newline). You then get:

import StringIO
s = StringIO.StringIO(myString)
for line in s:
    do_something_with(line)

Let's take an example. If your table has columns as follows:

<!-- ID Column -->
  <ng-container matColumnDef="id" >
    <th mat-header-cell *matHeaderCellDef mat-sort-header> ID </th>
    <td mat-cell *matCellDef="let row"> {{row.sid}} </td>
  </ng-container>

 <!-- Name Column -->
  <ng-container matColumnDef="name">
    <th mat-header-cell *matHeaderCellDef mat-sort-header> Name </th>
    <td mat-cell *matCellDef="let row"> {{row.name}} </td>
  </ng-container>

As this contain two columns. then we can set the width of columns using

.mat-column-<matColumnDef-value>{
    width: <witdh-size>% !important;
}

for this example, we take

  .mat-column-id{
    width: 20% !important;      
  }
  .mat-column-name{
    width: 80% !important;
  }

Often I'll put trivial member functions into the header file, to allow them to be inlined. But to put the entire body of code there, just to be consistent with templates? That's plain nuts.

Remember: A foolish consistency is the hobgoblin of little minds.

Using 2.7:

from functools import partial
from random import randint

for roll in iter(partial(randint, 1, 8), 1):
    print 'you rolled: {}'.format(roll)
print 'oops you rolled a 1!'

you rolled: 7
you rolled: 7
you rolled: 8
you rolled: 6
you rolled: 8
you rolled: 5
oops you rolled a 1!

Then change the "oops" print to a raise SystemExit

I think MAVEN_OPTS would be most appropriate for you. See here: http://maven.apache.org/configure.html

In Unix:

Add the MAVEN_OPTS environment variable to specify JVM properties, e.g. export MAVEN_OPTS="-Xms256m -Xmx512m". This environment variable can be used to supply extra options to Maven.

In Win, you need to set environment variable via the dialogue box

Add ... environment variable by opening up the system properties (WinKey + Pause),... In the same dialog, add the MAVEN_OPTS environment variable in the user variables to specify JVM properties, e.g. the value -Xms256m -Xmx512m. This environment variable can be used to supply extra options to Maven.

PowerShell is a very powerful and efficient tool. This is cheating a little, but shelling PowerShell via VBA opens up lots of options

The bulk of the code below is simply to save the current sheet as a csv file. The output is another csv file with just the unique values

Sub AnotherWay()
Dim strPath As String
Dim strPath2 As String

Application.DisplayAlerts = False
strPath = "C:\Temp\test.csv"
strPath2 = "C:\Temp\testout.csv"
ActiveWorkbook.SaveAs strPath, xlCSV
x = Shell("powershell.exe $csv = import-csv -Path """ & strPath & """ -Header A | Select-Object -Unique A | Export-Csv """ & strPath2 & """ -NoTypeInformation", 0)
Application.DisplayAlerts = True

End Sub

a = [2,3,4,5,6,7,8,9,0]
xyz = [0,12,4,6,242,7,9]  
set(a) & set(xyz)  
set([0, 9, 4, 6, 7])

When a module is loaded from a file in Python, __file__ is set to its path. You can then use that with other functions to find the directory that the file is located in.

Taking your examples one at a time:

A = os.path.join(os.path.dirname(__file__), '..')
# A is the parent directory of the directory where program resides.

B = os.path.dirname(os.path.realpath(__file__))
# B is the canonicalised (?) directory where the program resides.

C = os.path.abspath(os.path.dirname(__file__))
# C is the absolute path of the directory where the program resides.

You can see the various values returned from these here:

import os
print(__file__)
print(os.path.join(os.path.dirname(__file__), '..'))
print(os.path.dirname(os.path.realpath(__file__)))
print(os.path.abspath(os.path.dirname(__file__)))

and make sure you run it from different locations (such as ./text.py, ~/python/text.py and so forth) to see what difference that makes.

I just want to address some confusion first. __file__ is not a wildcard it is an attribute. Double underscore attributes and methods are considered to be "special" by convention and serve a special purpose.

http://docs.python.org/reference/datamodel.html shows many of the special methods and attributes, if not all of them.

In this case __file__ is an attribute of a module (a module object). In Python a .py file is a module. So import amodule will have an attribute of __file__ which means different things under difference circumstances.

Taken from the docs:

__file__ is the pathname of the file from which the module was loaded, if it was loaded from a file. The __file__ attribute is not present for C modules that are statically linked into the interpreter; for extension modules loaded dynamically from a shared library, it is the pathname of the shared library file.

In your case the module is accessing it's own __file__ attribute in the global namespace.

To see this in action try:

# file: test.py

print globals()
print __file__

And run:

python test.py

{'__builtins__': <module '__builtin__' (built-in)>, '__name__': '__main__', '__file__':
 'test_print__file__.py', '__doc__': None, '__package__': None}
test_print__file__.py

Use shell=True if you're passing a string to subprocess.call.

From docs:

If passing a single string, either shell must be True or else the string must simply name the program to be executed without specifying any arguments.

subprocess.call(crop, shell=True)

or:

import shlex
subprocess.call(shlex.split(crop))

For number with decimal fraction and minus sign, I use this snippet:

const NUMERIC_REGEXP = /[-]{0,1}[\d]*[.]{0,1}[\d]+/g;

const numbers = '2.2px 3.1px 4px -7.6px obj.key'.match(NUMERIC_REGEXP)

console.log(numbers); // ["2.2", "3.1", "4", "-7.6"]

Update: - 7/9/2018

Found a tool which allows you to edit regular expression visually: JavaScript Regular Expression Parser & Visualizer.

Update:

Here's another one with which you can even debugger regexp: Online regex tester and debugger.

As the question title asks for a regex that finds many dates, I would like to propose a new solution, although there are many solutions already.

In order to find all dates of a string that are in this millennium (2000 - 2999), for me it worked the following:

dates = re.findall('([1-9]|1[0-9]|2[0-9]|3[0-1]|0[0-9])(.|-|\/)([1-9]|1[0-2]|0[0-9])(.|-|\/)(20[0-9][0-9])',dates_ele)

dates = [''.join(dates[i]) for i in range(len(dates))]

This regex is able to find multiple dates in the same string, like bla Bla 8.05/2020 \n BLAH bla15/05-2020 blaa. As one could observe, instead of / the date can have . or -, not necessary at the same time.

Some explaining

More specifically it can find dates of format day , moth year. Day is an one digit integer or a zero followed by one digit integer or 1 or 2 followed by an one digit integer or a 3 followed by 0 or 1. Month is an one digit integer or a zero followed by one digit integer or 1 followed by 0, 1, or 2. Year is the number 20 followed by any number between 00 and 99.

Useful notes

One can add more date splitting symbols by adding | symbol at the end of both (.|-|\/). For example for adding -- one would do (.|-|\/|--)

To have years outside of this millennium one has to modify (20[0-9][0-9]) to ([0-9][0-9][0-9][0-9])

performance wise, my (crude) measurements found no difference on 1000 writes and reads

security wise, intuitively it would seem the localStore might be shut down before the sessionStore, but have no concrete evidence - maybe someone else does?

functional wise, concur with digitalFresh above

Since eggyal didn't provided his comment as answer after he gave right advice in a comment - i am posting it here: In my case I had to install module php-mysql. See comments under the question for details.

Comment out these two lines in php.ini

;extension=imagick.so
;extension="ixed.5.6.lin"

it should fix the issue.

I think you can use JSON.stringify:

// after your each loop
JSON.stringify(values);

return=[entry for tag in tags for entry in entries if tag in entry for entry in entry]

The modern way to do this is with flexbox, adding align-items: flex-end; on the container.

With this content:

<div class="Container">
  <div>one</div>
  <div>two</div>
</div>

Use this style:

.Container {
  display: flex;
  align-items: flex-end;
}

You should set the AllowRating property to true, preferably in the controller or model.
Like other inputs, the checkbox's state reflects the value of the property.

cURL is an option, using Ajax as well eventhough solving back-end problems with the front-end isn't so neat.

A very useful post about doing it without cURL is this one: http://netevil.org/blog/2006/nov/http-post-from-php-without-curl

The code to do this (untested, unimproved, from the blog post):

function do_post_request($url, $data, $optional_headers = null)
{
   $params = array('http' => array(
                'method' => 'POST',
                'content' => $data
             ));
   if ($optional_headers !== null) {
      $params['http']['header'] = $optional_headers;
   }
   $ctx = stream_context_create($params);
   $fp = @fopen($url, 'rb', false, $ctx);
   if (!$fp) {
      throw new Exception("Problem with $url, $php_errormsg");
   }
   $response = @stream_get_contents($fp);
   if ($response === false) {
      throw new Exception("Problem reading data from $url, $php_errormsg");
   }
   return $response;
}

by default <UL/> contains default padding

therefore try adding style to padding:0px in css class or inline css

All proposed solutions didn't work for me but the closest one was from @Rishii.

I'm using AngularJS 1.4.4 and UI Bootstrap 0.13.3.

.directive('jsr310Compatible', ['dateFilter', 'dateParser', function(dateFilter, dateParser) {
  return {
    restrict: 'EAC',
    require: 'ngModel',
    priority: 1,
    link: function(scope, element, attrs, ngModel) {
      var dateFormat = 'yyyy-MM-dd';

      ngModel.$parsers.push(function(viewValue) {
        return dateFilter(viewValue, dateFormat);
      });

      ngModel.$validators.date = function (modelValue, viewValue) {
        var value = modelValue || viewValue;

        if (!attrs.ngRequired && !value) {
          return true;
        }

        if (angular.isNumber(value)) {
          value = new Date(value);
        }

        if (!value) {
          return true;
        }
        else if (angular.isDate(value) && !isNaN(value)) {
          return true;
        }
        else if (angular.isString(value)) {
          var date = dateParser.parse(value, dateFormat);
          return !isNaN(date);
        }
        else {
          return false;
        }
      };
    }
  };

If you are running on Redhat, do following

1. Stop Jenkins
   $sudo service jenkins stop

2. change port number in /etc/sysconfig/jenkins like i did for port 8081
   JENKINS_PORT="8081"

3. start Jenkins again
   $sudo service jenkins start

make sure your FW has correct burn rules.

if you're using NSNotificationCenter for updating your view, don't forget to send it from the main thread by calling dispatch_async:

dispatch_async(dispatch_get_main_queue(),^{
    [[NSNotificationCenter defaultCenter] postNotificationName:@"my_notification" object:nil];
});

Yes, there's a command git commit --amend which is used to "fix" last commit.

In your case it would be called as:

git add the_left_out_file
git commit --amend --no-edit

The --no-edit flag allow to make amendment to commit without changing commit message.

EDIT: Warning You should never amend public commits, that you already pushed to public repository, because what amend does is actually removing from history last commit and creating new commit with combined changes from that commit and new added when amending.

One of the way is Using below sql queries

--Size of All Table Space

--1. Used Space
SELECT TABLESPACE_NAME,TO_CHAR(SUM(NVL(BYTES,0))/1024/1024/1024, '99,999,990.99') AS "USED SPACE(IN GB)" FROM USER_SEGMENTS GROUP BY TABLESPACE_NAME
--2. Free Space
SELECT TABLESPACE_NAME,TO_CHAR(SUM(NVL(BYTES,0))/1024/1024/1024, '99,999,990.99') AS "FREE SPACE(IN GB)" FROM   USER_FREE_SPACE GROUP BY TABLESPACE_NAME

--3. Both Free & Used
SELECT USED.TABLESPACE_NAME, USED.USED_BYTES AS "USED SPACE(IN GB)",  FREE.FREE_BYTES AS "FREE SPACE(IN GB)"
FROM
(SELECT TABLESPACE_NAME,TO_CHAR(SUM(NVL(BYTES,0))/1024/1024/1024, '99,999,990.99') AS USED_BYTES FROM USER_SEGMENTS GROUP BY TABLESPACE_NAME) USED

Tested and works on Android HTC Sense and Apple iPad.

**old_list = [[0,1,'f'], [4,2,'t'],[9,4,'afsd']]
    #let's assume we want to sort lists by last value ( old_list[2] )
    new_list = sorted(old_list, key=lambda x: x[2])**

correct me if i'm wrong but isnt the 'x[2]' calling the 3rd item in the list, not the 3rd item in the nested list? should it be x[2][2]?

According to the go documentation, Unix returns a local time.

Unix returns the local Time corresponding to the given Unix time

This means the output would depend on the machine your code runs on, which, most often is what you need, but sometimes, you may want to have the value in UTC.

To do so, I adapted the snippet to make it return a time in UTC:

i, err := strconv.ParseInt("1405544146", 10, 64)
if err != nil {
    panic(err)
}
tm := time.Unix(i, 0)
fmt.Println(tm.UTC())

This prints on my machine (in CEST)

2014-07-16 20:55:46 +0000 UTC

You go into your router configuration and forward port 80 to the LAN IP of the computer running the web server.

Then anyone outside your network (but not you inside the network) can access your site using your WAN IP address (whatismyipcom).

Commit Changes

Once you've edited a file, you need to commit your changes to git. When you execute this command it will ask for a commit message - which is just a simple bit of text that tells everyone what you've changed.

$ git commit source/main.c

Will commit the file main.c in the directory ./source/

$ git commit -a # the -a flag pulls in all modified files

will commit all changed files (but not new files, those need to be added to the index with git-add). If you want to commit only certain files then you will need to stage them first with git-add and then commit without the -a flag.

Commiting only changes your local repository though not the remote repositories. If you want to send the commits to the remote repository then you will need to do a push.

$ git push <remote> <branch> # push new commits to the <branch> on the <remote> repository

For someone coming from CVS or SVN this is a change since the commit to the central repository now requires two steps.

I had the same issue, but I have resolved it the next:

1) Install jdk1.8...

2) In AndroidStudio File->Project Structure->SDK Location, select your directory where the JDK is located, by default Studio uses embedded JDK but for some reason it produces error=216.

3) Click Ok.

You can achieve this using exists:

DELETE
  FROM table1
 WHERE exists(
           SELECT 1
             FROM table2
            WHERE table2.stn = table1.stn
              and table2.jaar = year(table1.datum)
       )

In 2017, what is working for me is simply this one line

navigationController?.navigationBar.isTranslucent = false

I have no idea why that would even affect it. Perhaps someone could explain. But I'm pretty sure this is the answer most people would look for.

The color and window sizing are defined by the shortcut LNK file. I think I found a way that will do what you need, try this:

explorer.exe "Windows PowerShell.lnk"

The LNK file is in the all user start menu which is located in different places depending whether your on XP or Windows 7. In 7 the LNK file is here:

C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Accessories\Windows PowerShell

If you have multiple Action within same file then pass the same argument e.g. Id to all Action. This is because action only can identify Id, So instead of giving any name to argument only declare Id like this.

[httpget]
[ActionName("firstAction")] firstAction(string Id)
{.....
.....
}
[httpget]
[ActionName("secondAction")] secondAction(Int Id)
{.....
.....
}
//Now go to webroute.config file under App-start folder and add following
routes.MapHttpRoute(
name: "firstAction",
routeTemplate: "api/{controller}/{action}/{id}",
defaults: new { id = RouteParameter.Optional }
);

routes.MapHttpRoute(
name: "secondAction",
routeTemplate: "api/{controller}/{action}/{id}",
defaults: new { id = RouteParameter.Optional }
);

I found this the quick and easy way: Used: org.json.XML class from java-json.jar

if (statusCode == 200 && inputStream != null) {
    BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream, "UTF-8"));
    StringBuilder responseStrBuilder = new StringBuilder();

    String inputStr;
    while ((inputStr = bufferedReader.readLine()) != null) {
        responseStrBuilder.append(inputStr);
    }

    jsonObject = XML.toJSONObject(responseStrBuilder.toString());
}

In command line/CLI, you will get this error if your current directory is NOT the repository. So, you have to first CD into the repo.

although it is invalid html but you can use selector context to limit your selector in your case it would be like :

$("input[name='name']" , "#form2").val("Hello World! ");

You can experiment with model.summary() (notice the concatenate_XX (Concatenate) layer size)

# merge samples, two input must be same shape
inp1 = Input(shape=(10,32))
inp2 = Input(shape=(10,32))
cc1 = concatenate([inp1, inp2],axis=0) # Merge data must same row column
output = Dense(30, activation='relu')(cc1)
model = Model(inputs=[inp1, inp2], outputs=output)
model.summary()

# merge row must same column size
inp1 = Input(shape=(20,10))
inp2 = Input(shape=(32,10))
cc1 = concatenate([inp1, inp2],axis=1)
output = Dense(30, activation='relu')(cc1)
model = Model(inputs=[inp1, inp2], outputs=output)
model.summary()

# merge column must same row size
inp1 = Input(shape=(10,20))
inp2 = Input(shape=(10,32))
cc1 = concatenate([inp1, inp2],axis=1)
output = Dense(30, activation='relu')(cc1)
model = Model(inputs=[inp1, inp2], outputs=output)
model.summary()

You can use the runOnUiThread() method as follows. If you're not using a ListActivity, just adapt the code to get a reference to your ArrayAdapter.

final ArrayAdapter adapter = ((ArrayAdapter)getListAdapter());
runOnUiThread(new Runnable() {
    public void run() {
        adapter.notifyDataSetChanged();
    }
});

I think the better answer for this questions is

array_diff() 

because it Compares array against one or more other arrays and returns the values in array that are not present in any of the other arrays.

Whereas

array_intersect() returns an array containing all the values of array that are present in all the arguments. Note that keys are preserved.

Open the Mac Terminal:

vi ~/.bashrc

If you haven't used vi, it may look a little funny at first, so enter the following code carefully, in order:

i
export PATH="$PATH:$HOME/.composer/vendor/bin"

PRESS ESC

:
w

PRESS ENTER

:
q

PRESS ENTER

Now you should have returned to the normal terminal view.

Check that composer now has the correct path:

cd ~/.composer
echo $PATH

If you see the path including your file directory, (e.g. /Users/JeffStrongman/.composer/vendor/bin), you're good to go.

cd

Then run your installation. I ran into this problem, while configuring my Mac to use Laravel Valet.

Example (optional)

valet install

The ! should be around the outside of the statement:

data[!(data$v1 %in% c("b", "d", "e")), ]

  v1 v2 v3 v4
1  a  v  d  c
2  a  v  d  d
5  c  k  d  c
6  c  r  p  g

You can make a new file under [.git\refs\remotes\origin] with name "HEAD" and put content "ref: refs/remotes/origin/master" to it. This should solve your problem.

It seems that clone from an empty repos will lead to this. Maybe the empty repos do not have HEAD because no commit object exist.

You can use the

git log --remotes --branches --oneline --decorate

to see the difference between each repository, while the "problem" one do not have "origin/HEAD"

Edit: Give a way using command line
You can also use git command line to do this, they have the same result

git symbolic-ref refs/remotes/origin/HEAD refs/remotes/origin/master

Try this piece of code, rather than ObjectInputStream.

BufferedReader in = new BufferedReader (new InputStreamReader (socket.getInputStream ()));
while (true)
{
    String cominginText = "";
    try
    {
        cominginText = in.readLine ();
        System.out.println (cominginText);
    }
    catch (IOException e)
    {
        //error ("System: " + "Connection to server lost!");
        System.exit (1);
        break;
    }
}

You don't need a IF statement at all.

WHERE
    (IsNumeric(@OrderNumber) = 1 AND OrderNumber = @OrderNumber)
OR (IsNumeric(@OrderNumber) = 0 AND OrderNumber LIKE '%' + @OrderNumber + '%')

For SQL Server version 9.0 (2005), you can use the code below:

select * 
from 
syscomments c
inner join sys.procedures p on p.object_id = c.id
where 
p.name like '%usp_ConnectionsCount%';

In case of huge tables standard way with sorting by dbms_random.value is not effective because you need to scan whole table and dbms_random.value is pretty slow function and requires context switches. For such cases, there are 3 additional methods:

1: Use sample clause:

• https://docs.oracle.com/en/database/oracle/oracle-database/19/sqlrf/SELECT.html#GUID-CFA006CA-6FF1-4972-821E-6996142A51C6
• https://docs.oracle.com/en/database/oracle/oracle-database/19/sqlrf/SELECT.html#GUID-CFA006CA-6FF1-4972-821E-6996142A51C6

for example:

select *
from s1 sample block(1)
order by dbms_random.value
fetch first 1 rows only

ie get 1% of all blocks, then sort them randomly and return just 1 row.

2: if you have an index/primary key on the column with normal distribution, you can get min and max values, get random value in this range and get first row with a value greater or equal than that randomly generated value.

Example:

--big table with 1 mln rows with primary key on ID with normal distribution:
Create table s1(id primary key,padding) as 
   select level, rpad('x',100,'x')
   from dual 
   connect by level<=1e6;

select *
from s1 
where id>=(select 
              dbms_random.value(
                 (select min(id) from s1),
                 (select max(id) from s1) 
              )
           from dual)
order by id
fetch first 1 rows only;

3: get random table block, generate rowid and get row from the table by this rowid:

select * 
from s1
where rowid = (
   select
      DBMS_ROWID.ROWID_CREATE (
         1, 
         objd,
         file#,
         block#,
         1) 
   from    
      (
      select/*+ rule */ file#,block#,objd
      from v$bh b
      where b.objd in (select o.data_object_id from user_objects o where object_name='S1' /* table_name */)
      order by dbms_random.value
      fetch first 1 rows only
      )
);

I do this frequently using Table Types to ensure more consistency and simplify code. You can't technically return "a table", but you can return a result set and using INSERT INTO .. EXEC ... syntax, you can clearly call a PROC and store the results into a table type. In the following example I'm actually passing a table into a PROC along with another param I need to add logic, then I'm effectively "returning a table" and can then work with that as a table variable.

/****** Check if my table type and/or proc exists and drop them ******/
IF EXISTS (SELECT * FROM sys.objects WHERE type = 'P' AND name = 'returnTableTypeData')
DROP PROCEDURE returnTableTypeData
GO
IF EXISTS (SELECT * FROM sys.types WHERE is_table_type = 1 AND name = 'myTableType')
DROP TYPE myTableType
GO

/****** Create the type that I'll pass into the proc and return from it ******/
CREATE TYPE [dbo].[myTableType] AS TABLE(
    [someInt] [int] NULL,
    [somenVarChar] [nvarchar](100) NULL
)
GO

CREATE PROC returnTableTypeData
    @someInputInt INT,
    @myInputTable myTableType READONLY --Must be readonly because
AS
BEGIN

    --Return the subset of data consistent with the type
    SELECT
        *
    FROM
        @myInputTable
    WHERE
        someInt < @someInputInt

END
GO


DECLARE @myInputTableOrig myTableType
DECLARE @myUpdatedTable myTableType

INSERT INTO @myInputTableOrig ( someInt,somenVarChar )
VALUES ( 0, N'Value 0' ), ( 1, N'Value 1' ), ( 2, N'Value 2' )

INSERT INTO @myUpdatedTable EXEC returnTableTypeData @someInputInt=1, @myInputTable=@myInputTableOrig

SELECT * FROM @myUpdatedTable


DROP PROCEDURE returnTableTypeData
GO
DROP TYPE myTableType
GO

The following adds elements to a list in a loop.

l<-c()
i=1

while(i<100) {

    b<-i
    l<-c(l,b)
    i=i+1
}

apache commons lang has a class SystemUtils.java you can use :

SystemUtils.IS_OS_LINUX
SystemUtils.IS_OS_WINDOWS

Just add the document ready function, this way it waits until the DOM has been loaded, also by using the :visible pseudo you can write a simple show and hide function.

Sample

 $(document).ready(function(){

    $( '.expand' ).click(function() {
         if($( '.img_display_content' ).is(":visible")){
              $( '.img_display_content' ).hide();
         } else{
              $( '.img_display_content' ).show();
         }

    });
});

You can of course format the result of current_timestamp(). Please have a look at the various formatting functions in the official documentation.

Swift will not allow you to initialise super class with out initialising the properties, reverse of Obj C. So you have to initialise all properties before calling "super.init".

Please go to http://blog.scottlogic.com/2014/11/20/swift-initialisation.html. It gives a nice explanation to your problem.

FormulaR1C1 has the same behavior as Formula, only using R1C1 style annotation, instead of A1 annotation. In A1 annotation you would use:

Worksheets("Sheet1").Range("A5").Formula = "=A4+A10"

In R1C1 you would use:

Worksheets("Sheet1").Range("A5").FormulaR1C1 = "=R4C1+R10C1"

It doesn't act upon row 1 column 1, it acts upon the targeted cell or range. Column 1 is the same as column A, so R4C1 is the same as A4, R5C2 is B5, and so forth.

The command does not change names, the targeted cell changes. For your R2C3 (also known as C2) example :

Worksheets("Sheet1").Range("C2").FormulaR1C1 = "=your formula here"

filepath.Abs("./")

Abs returns an absolute representation of path. If the path is not absolute it will be joined with the current working directory to turn it into an absolute path.

As stated in the comment, this returns the directory which is currently active.

If you know the ratio of the image at build time, want the height based off of the window height and you're ok targeting modern browsers (IE9+), then you can use viewport units for this:

.width-ratio-of-height {
  overflow-x: scroll;
  height: 100vh;
  width: 500vh; /* width here is 5x height */
  background-image: url("http://placehold.it/5000x1000");
  background-size: cover;
}

Not quite what the OP was asking, but probably a good fit for a lot of those viewing this question, so wanted to give another option here.

Fiddle: https://jsfiddle.net/6Lkzdnge/

The most straigthforward way that makes full use of the huge TimeZone Database of Java and is correct:

long currentTime = new Date().getTime();
long dateOnly = currentTime + TimeZone.getDefault().getOffset(currentTime);

From the MSDN website:

This error frequently occurs if you declare a variable in a loop or a try or if block and then attempt to access it from an enclosing code block or a separate code block.

So declare the variable outside the block.

Get the invalid chars from System.IO.Path.GetInvalidPathChars(); and check if your string (Directory path) contains those or not.

So I have faced the same problem when trying to start apache service and I would like to share my solutions with you. Here is some notes about services or programs that may use port 80:

1. Skype: skype uses port 80/443 by default. You can change this from tools->options-> advanced->connections and uncheck the checkbox "use port 80 and 443 for addtional incoming connections".
2. IIS: IIS uses port 80 be default so you need to shut down it. You can use the following two commands net stop w3svc net stop iisadmin
3. SQL Server Reporting Service: You need to stop this service because it may take port 80 if IIS is not running. Go to local services and stop it.

These options work great with me and I can start apache service without errors.

The other option is to change apache listen port from httpd.conf and set another port number.

Hope this solution helps anyone who face the same problem again.

Have you tried jQuery.contents() ?

If someone is still interested, there is a simple javascript library (no jQuery dependency), named custom recaptcha. It lets you customize the button with css and implement some js events (ready/checked). The idea is to make the default recaptcha "invisible" and put a button over it. Just change the id of the recaptcha and that's it.

<head>
    <script src="https://azentreprise.org/download/custom-recaptcha.min.js"></script>
    <style type="text/css">
        #captcha {
            float: left;
            margin: 2%;

            background-color: rgba(72, 61, 139, 0.5); /* darkslateblue with 50% opacity */
            border-radius: 2px;

            font-size: 1em;
            color: #C0FFEE;
        }

        #captcha.success {
            background-color: rgba(50, 205, 50, 0.5); /* limegreen with 50% opacity */
            color: limegreen;
        }
    </style>
</head>
<body>
    <div id="captcha" data-sitekey="your_site_key" data-label="Click here" data-label-spacing="15"></div>
</body>

See https://azentreprise.org/read.php?id=1 for more information.

when you do UNIQUE as a table level constraint as you have done then what your defining is a bit like a composite primary key see ddl constraints, here is an extract

"This specifies that the *combination* of values in the indicated columns is unique across the whole table, though any one of the columns need not be (and ordinarily isn't) unique."

this means that either field could possibly have a non unique value provided the combination is unique and this does not match your foreign key constraint.

most likely you want the constraint to be at column level. so rather then define them as table level constraints, 'append' UNIQUE to the end of the column definition like name VARCHAR(60) NOT NULL UNIQUE or specify indivdual table level constraints for each field.

Almost always List is preferred over ArrayList because, for instance, List can be translated into a LinkedList without affecting the rest of the codebase.

If one used ArrayList instead of List, it's hard to change the ArrayList implementation into a LinkedList one because ArrayList specific methods have been used in the codebase that would also require restructuring.

You can read about the List implementations here.

You may start with an ArrayList, but soon after discover that another implementation is the more appropriate choice.

I would recommend using mingw/msys as a development environment. Especially if you are porting simple console programs. Msys implements a Unix-like shell on Windows, and mingw is a port of the GNU compiler collection (GCC) and other GNU build tools to the Windows platform. It is an open-source project, and well-suited to the task. I currently use it to build utility programs and console applications for Windows XP, and it most certainly has that unistd.h header you are looking for.

The install procedure can be a little bit tricky, but I found that the best place to start is in MSYS.

BinaryFormatter bf = new BinaryFormatter();
byte[] bytes;
MemoryStream ms = new MemoryStream();

string orig = "? Hello ?? Thank You";
bf.Serialize(ms, orig);
ms.Seek(0, 0);
bytes = ms.ToArray();

MessageBox.Show("Original bytes Length: " + bytes.Length.ToString());

MessageBox.Show("Original string Length: " + orig.Length.ToString());

for (int i = 0; i < bytes.Length; ++i) bytes[i] ^= 168; // pseudo encrypt
for (int i = 0; i < bytes.Length; ++i) bytes[i] ^= 168; // pseudo decrypt

BinaryFormatter bfx = new BinaryFormatter();
MemoryStream msx = new MemoryStream();            
msx.Write(bytes, 0, bytes.Length);
msx.Seek(0, 0);
string sx = (string)bfx.Deserialize(msx);

MessageBox.Show("Still intact :" + sx);

MessageBox.Show("Deserialize string Length(still intact): " 
    + sx.Length.ToString());

BinaryFormatter bfy = new BinaryFormatter();
MemoryStream msy = new MemoryStream();
bfy.Serialize(msy, sx);
msy.Seek(0, 0);
byte[] bytesy = msy.ToArray();

MessageBox.Show("Deserialize bytes Length(still intact): " 
   + bytesy.Length.ToString());

You can do it with the HTMLWorker class (deprecated) like this:

import com.itextpdf.text.html.simpleparser.HTMLWorker;
//...
try {
    String k = "<html><body> This is my Project </body></html>";
    OutputStream file = new FileOutputStream(new File("C:\\Test.pdf"));
    Document document = new Document();
    PdfWriter.getInstance(document, file);
    document.open();
    HTMLWorker htmlWorker = new HTMLWorker(document);
    htmlWorker.parse(new StringReader(k));
    document.close();
    file.close();
} catch (Exception e) {
    e.printStackTrace();
}

or using the XMLWorker, (download from this jar) using this code:

import com.itextpdf.tool.xml.XMLWorkerHelper;
//...
try {
    String k = "<html><body> This is my Project </body></html>";
    OutputStream file = new FileOutputStream(new File("C:\\Test.pdf"));
    Document document = new Document();
    PdfWriter writer = PdfWriter.getInstance(document, file);
    document.open();
    InputStream is = new ByteArrayInputStream(k.getBytes());
    XMLWorkerHelper.getInstance().parseXHtml(writer, document, is);
    document.close();
    file.close();
} catch (Exception e) {
    e.printStackTrace();
}

it looks like you need a rule very similar to your checked rule

http://jsfiddle.net/VWBN4/3

#ck-button input:hover + span {
    background-color:#191;
    color:#fff;
}

and for hover and clicked state:

#ck-button input:checked:hover + span {
    background-color:#c11;
    color:#fff;
}

the order is important though.

Try this and tell my if it works hope it help you:

string value = Convert.ToString(Console.ReadLine());

Switch(value)
{
    Case "abc":

    break;

    default:

    break;
}       

Although I have not tried this out, ProcDump seems like a better solution.

Description from site:

ProcDump is a command-line utility whose primary purpose is monitoring an application for CPU spikes and generating crash dumps during a spike that an administrator or developer can use to determine the cause of the spike. ProcDump also includes hung window monitoring (using the same definition of a window hang that Windows and Task Manager use), unhandled exception monitoring and can generate dumps based on the values of system performance counters. It also can serve as a general process dump utility that you can embed in other scripts.

The whole lot is encrypted^† - all the headers. That's why SSL on vhosts doesn't work too well - you need a dedicated IP address because the Host header is encrypted.

^†The Server Name Identification (SNI) standard means that the hostname may not be encrypted if you're using TLS. Also, whether you're using SNI or not, the TCP and IP headers are never encrypted. (If they were, your packets would not be routable.)

I somehow absolutely missed the actual command in the accepted answer, so here it is again, bit more visible in its own paragraph, to see how many people are like me

$ docker history --no-trunc <IMAGE_ID>

Map files (source maps) are there to de-reference minified code (css and javascript).

And they are mainly used to help developers debugging a production environment, because developers usually use minified files for production which makes it impossible to debug. Map files help them de-referencing the code to see how the original file looked like.

RelativeLayout works the same way, the last image in the relative layout wins.

Where you have a posted date in format dd/mm/yyyy, use the below:

$date = explode('/', $_POST['posted_date']);
$new_date = $date[2].'-'.$date[1].'-'.$date[0];

If you have it in mm/dd/yyyy, just change the second line:

$new_date = $date[2].'-'.$date[0].'-'.$date[1];

If you have Composer installed globally, you can install the Laravel installer tool using command below:

composer global require "laravel/installer=~1.1"

You can use document.write or even console.write (this is good for debugging).

But your best bet and it gives you more control is to use DOM to update the page.

You are overwriting the start date object with the value of a DOM Element with an id of Startdate.

This should work:

var start = new Date(document.getElementById('Stardate').value);

var y = start.getFullYear();

Another way of doing this: new_df = A_df.merge(B_df, left_on=['A_c1','c2'], right_on = ['B_c1','c2'], how='left')

I rename my own just by simply :

1. going to github.com on my repository
2. Open Settings Tab
3. The first setting you can see is the "Repository Name"
4. Change the actual one and put the new name you want to give to your repository
5. Click on "Rename" button

After this step, GitHub will make sure that, your online repository matches your local folder name. At this step your problem is solved, unless you also want to rename your local folder. Then do it manually and just use the Github client for windows to refind again your repository into your hard drive, and Github will match it again. That's all! Very simple.

This is because You're sorting entire result-set, You should sort, every part of union separately, or You can use ORDER BY (Something ie. subquery distance) THEN (something ie row id) clause

Thanks for Ben's solution, my use case to display only particular fields in order

with object

Code:

    handlebars.registerHelper('eachToDisplayProperty', function(context, toDisplays, options) {
    var ret = "";
    var toDisplayKeyList = toDisplays.split(",");
    for(var i = 0; i < toDisplayKeyList.length; i++) {
        toDisplayKey = toDisplayKeyList[i];
        if(context[toDisplayKey]) {
            ret = ret + options.fn({
                property : toDisplayKey,
                value : context[toDisplayKey]
            });
        }

    }
    return ret;
});

Source object:

   { locationDesc:"abc", name:"ghi", description:"def", four:"you wont see this"}

Template:

{{#eachToDisplayProperty this "locationDesc,description,name"}}
    <div>
        {{property}} --- {{value}}
    </div>
    {{/eachToDisplayProperty}}

Output:

locationDesc --- abc
description --- def
name --- ghi

As of 2021 insted of null i had to add {} in order to make it work!

Use the built-in python function quit() and that's it. No need to import any library. I'm using python 3.4

You Can simply Use One Jsp Page To accomplish the task.

<%@page contentType="text/html" pageEncoding="UTF-8"%>
<%@page import="java.sql.*"%>
<!DOCTYPE html>
<html>
   <head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    <title>JSP Page</title>
</head>
<body>
    <%
        String username=request.getParameter("user_name");
        String password=request.getParameter("password");
        String role=request.getParameter("role");
        try
        {
            Class.forName("com.mysql.jdbc.Driver");
            Connection con=DriverManager.getConnection("jdbc:mysql://localhost:3306/t_fleet","root","root");
            Statement st=con.createStatement();
            String query="select * from tbl_login where user_name='"+username+"' and password='"+password+"' and role='"+role+"'";
            ResultSet rs=st.executeQuery(query);
            while(rs.next())
            {
                session.setAttribute( "user_name",rs.getString(2));
                session.setMaxInactiveInterval(3000);
                response.sendRedirect("homepage.jsp");
            }
            %>



        <%}
        catch(Exception e)
        {
            out.println(e);
        }
    %>

</body>

I have use username, password and role to get into the system. One more thing to implement is you can do page permission checking through jsp and javascript function.

If you have a single .java file to compile using command-line , then remove topmost package parts from the code, the compile again, it will work.

This worked for me.

As @epascarello mentioned for W3C standard browsers, you should use:

body.addEventListener("load", init, false);

However, if you want it to work on IE<9 as well you can use:

var prefix = window.addEventListener ? "" : "on";
var eventName = window.addEventListener ? "addEventListener" : "attachEvent";
document.body[eventName](prefix + "load", init, false);

Or if you want it in a single line:

document.body[window.addEventListener ? 'addEventListener' : 'attachEvent'](
    window.addEventListener ? "load" : "onload", init, false);

Note: here I get a straight reference to the body element via the document, saving the need for the first line.

Also, if you're using jQuery, and you want to use the DOM ready event rather than when the body loads, the answer can be even shorter...

$(init);

I personally needed a table with both the left and top headers visible at all times. Inspired by several articles, I think I have a good solution that you may find helpful. This version does not have the wrapping problem that other soltions have with floating divs or flexible/auto sizing of columns and rows.

aiohttp can be used with HTTP proxy already:

import asyncio
import aiohttp


@asyncio.coroutine
def do_request():
    proxy_url = 'http://localhost:8118'  # your proxy address
    response = yield from aiohttp.request(
        'GET', 'http://google.com',
        proxy=proxy_url,
    )
    return response

loop = asyncio.get_event_loop()
loop.run_until_complete(do_request())

<TextInput autoCapitalize={'none'} maxLength={10} placeholder='Mobile Number'  value={this.state.mobile} onChangeText={(mobile) => this.onChanged(mobile)}/>

and onChanged method :

onChanged(text){
   var newText = '';
   var numbers = '0123456789';
   if(text.length < 1){
     this.setState({ mobile: '' });
   }
   for (var i=0; i < text.length; i++) {
        if(numbers.indexOf(text[i]) > -1 ) {
             newText = newText + text[i];
        }
        this.setState({ mobile: newText });
    }
}

You can use QTextCodec to convert the bytearray to a string:

QString DataAsString = QTextCodec::codecForMib(1015)->toUnicode(Data);

(1015 is UTF-16, 1014 UTF-16LE, 1013 UTF-16BE, 106 UTF-8)

From your example we can see that the string "test" is encoded as "t\0 e\0 s\0 t\0 \0 \0" in your encoding, i.e. every ascii character is followed by a \0-byte, or resp. every ascii character is encoded as 2 bytes. The only unicode encoding in which ascii letters are encoded in this way, are UTF-16 or UCS-2 (which is a restricted version of UTF-16), so in your case the 1015 mib is needed (assuming your local endianess is the same as the input endianess).

SELECT id, name, form_id, DATE(updated_at) as date
FROM wp_frm_items
WHERE user_id = 11 && form_id=9
ORDER BY date ASC

"DESC" stands for descending but you need ascending order ("ASC").

This questions is already answered here. Just put height: 100% in both the div and the container td.

You can use the bootstrap grid system. as Yoann said

 <div class="container">
    <div class="row">
        <form role="form">
           <div class="form-group col-xs-10 col-sm-4 col-md-4 col-lg-4">
                        <label for="exampleInputEmail1">Email address</label>
                        <input type="email" class="form-control" id="exampleInputEmail1" placeholder="Enter email">
                    </div>
                    <div class="form-group col-xs-10 col-sm-4 col-md-4 col-lg-4">
                        <label for="exampleInputEmail1">Name</label>
                        <input type="text" class="form-control" id="exampleInputEmail1" placeholder="Enter Name">
                    </div>
                    <div class="clearfix"></div>
                    <div class="form-group col-xs-10 col-sm-4 col-md-4 col-lg-4">
                        <label for="exampleInputPassword1">Password</label>
                        <input type="password" class="form-control" id="exampleInputPassword1" placeholder="Password">
                    </div>
                    <div class="form-group col-xs-10 col-sm-4 col-md-4 col-lg-4">
                        <label for="exampleInputPassword1">Confirm Password</label>
                        <input type="password" class="form-control" id="exampleInputPassword1" placeholder="Confirm Password">
                    </div>

I did this in three steps by following the instructions here: This is all taken directly from here: http://ipython.readthedocs.io/en/stable/install/kernel_install.html. I'm currently running Python 2.x on Windows 8 and have Anaconda 4.2.13 installed.

1) First install the latest version of python:

conda create -n python3 python=3 ipykernel

2) Next activate python3

activate python3

3) Install the kernel:

python -m ipykernel install --user

If you have Python 3 installed and want to install 2, switch the 2 and the 3 above. When you open a new notebook, you can now choose between Python 2 or 3.

You would like to use code like this:

<form>
  <input type="checkbox" id="pizza" name="pizza" value="yes">
  <label for="pizza">I would like to order a</label>
  <select id="pizza_kind" name="pizza_kind">
    <option>(choose one)</option>
    <option value="margaritha">Margaritha</option>
    <option value="hawai">Hawai</option>
  </select>
  pizza.
</form>

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
<script>
  var update_pizza = function () {
    if ($("#pizza").is(":checked")) {
        $('#pizza_kind').prop('disabled', false);
    }
    else {
        $('#pizza_kind').prop('disabled', 'disabled');
    }
  };
  $(update_pizza);
  $("#pizza").change(update_pizza);
</script>

?Here is working example

// My original 'goto' means to get the version
$.fn.jquery

// Another *similar* option
$().jQuery

// If there is concern that there may be multiple implementations of `$` then:
jQuery.fn.jquery

Recently I have had issues using $.fn.jquery/$().jQuery on a few sites so I wanted to note a third simple command to pull the jQuery version.

If you get back a version number -- usually as a string -- then jQuery is loaded and that is what version you're working with. If not loaded then you should get back undefined or maybe even an error.

Pretty old question and I've seen a few people that have already mentioned my answer in comments. However, I find that sometimes great answers that are left as comments can go unnoticed; especially when there are a lot of comments to an answer you may find yourself digging through piles of them looking for a gem. Hopefully this helps someone out!

CMD + [ -> Go Previous

CMD + ] -> Go Next

==========

For OSX, cmd + [ and ] are the best choices to go back & forth, Since they are found so near to fingers, avoiding you wrist twisting a bit, one keypress lesser, ideal for users in vim mode.

As the OP requested, this works well with cmd + B which facilitates jumping inside/to the method/variable definition and comes back immediately using cmd + [. Give a try.

Using mockito, you can make the exception happen.

when(testingClassObj.testSomeMethod).thenThrow(new CustomException());

Using Junit5, you can assert exception, asserts whether that exception is thrown when testing method is invoked.

@Test
@DisplayName("Test assert exception")
void testCustomException(TestInfo testInfo) {
    final ExpectCustomException expectEx = new ExpectCustomException();

     InvalidParameterCountException exception = assertThrows(InvalidParameterCountException.class, () -> {
            expectEx.constructErrorMessage("sample ","error");
        });
    assertEquals("Invalid parametercount: expected=3, passed=2", exception.getMessage());
}

Find a sample here: assert exception junit

The concat() method is used to join two or more arrays. It does not change the existing arrays, it only returns a copy of the joined arrays.

array1 = array1.concat(array2, array3, array4, ..., arrayN);

There are a couple of approaches:

1. Use a Bag alorithm like the sets contained in Google Collections.

2. Create mutable container which you can use in the Map:

    class My{
        String word;
        int count;
    }

And use put("word", new My("Word") ); Then you can check if it exists and increment when adding.

Avoid rolling your own solution using lists, because if you get innerloop searching and sorting, your performance will stink. The first HashMap solution is actually quite fast, but a proper like that found in Google Collections is probably better.

Counting words using Google Collections, looks something like this:

    HashMultiset s = new HashMultiset();
    s.add("word");
    s.add("word");
    System.out.println(""+s.count("word") );

Using the HashMultiset is quite elegent, because a bag-algorithm is just what you need when counting words.

I hit the same error. I suspect you're using node 12 and gulp 3. That combination does not work: https://github.com/gulpjs/gulp/issues/2324

A previous workaround from Jan. does not work either: https://github.com/gulpjs/gulp/issues/2246

Solution: Either upgrade to gulp 4 or downgrade to an earlier node.

The best solution is to create a new branch with --orphan option as shown below

git checkout --orphan <branch name>

By this you will be able to create a new branch and directly checkout to the new branch. It will be a parentless branch.

By default the --orphan option doesn't remove the files in the working directory, so you can delete the working directory files by this:

git rm --cached -r

In details what the --orphan does:

--orphan <new_branch>
Create a new orphan branch, named <new_branch>, started from <start_point> and switch to it. The first commit made on this new branch will have no parents and it will be the root of a new history totally disconnected from all the other branches and commits.

The index and the working tree are adjusted as if you had previously run git checkout <start_point>. This allows you to start a new history that records a set of paths similar to <start_point> by easily running git commit -a to make the root commit.

This can be useful when you want to publish the tree from a commit without exposing its full history. You might want to do this to publish an open source branch of a project whose current tree is "clean", but whose full history contains proprietary or otherwise encumbered bits of code.

If you want to start a disconnected history that records a set of paths that is totally different from the one of <start_point>, then you should clear the index and the working tree right after creating the orphan branch by running git rm -rf . from the top level of the working tree. Afterwards you will be ready to prepare your new files, repopulating the working tree, by copying them from elsewhere, extracting a tarball, etc.

Number(new Date(2010, 6, 26))

Works the same way as things above. If you need seconds don't forget to / 1000

The problem is that undefined compared to null using == gives true. The common check for undefined is therefore done like this:

typeof x == "undefined"

this ensures the type of the variable is really undefined.

As noted in the release email, linked to from the release tweet and noted in large orange warning that appears on the front page of the documentation, and less orange, but still present, in the readme on the repository and the release on pypi:

xlrd has explicitly removed support for anything other than xls files.

In your case, the solution is to:

• make sure you are on a recent version of Pandas, at least 1.0.1, and preferably the latest release. 1.2 will make his even clearer.
• install openpyxl: https://openpyxl.readthedocs.io/en/stable/
• change your Pandas code to be:

  df1 = pd.read_excel(
       os.path.join(APP_PATH, "Data", "aug_latest.xlsm"),
       engine='openpyxl',
  )
  

HashSet is much faster than TreeSet (constant-time versus log-time for most operations like add, remove and contains) but offers no ordering guarantees like TreeSet.

HashSet

• the class offers constant time performance for the basic operations (add, remove, contains and size).
• it does not guarantee that the order of elements will remain constant over time
• iteration performance depends on the initial capacity and the load factor of the HashSet.
  • It's quite safe to accept default load factor but you may want to specify an initial capacity that's about twice the size to which you expect the set to grow.

TreeSet

• guarantees log(n) time cost for the basic operations (add, remove and contains)
• guarantees that elements of set will be sorted (ascending, natural, or the one specified by you via its constructor) (implements SortedSet)
• doesn't offer any tuning parameters for iteration performance
• offers a few handy methods to deal with the ordered set like first(), last(), headSet(), and tailSet() etc

Important points:

• Both guarantee duplicate-free collection of elements
• It is generally faster to add elements to the HashSet and then convert the collection to a TreeSet for a duplicate-free sorted traversal.
• None of these implementations are synchronized. That is if multiple threads access a set concurrently, and at least one of the threads modifies the set, it must be synchronized externally.
• LinkedHashSet is in some sense intermediate between HashSet and TreeSet. Implemented as a hash table with a linked list running through it, however,it provides insertion-ordered iteration which is not same as sorted traversal guaranteed by TreeSet.

So a choice of usage depends entirely on your needs but I feel that even if you need an ordered collection then you should still prefer HashSet to create the Set and then convert it into TreeSet.

• e.g. SortedSet<String> s = new TreeSet<String>(hashSet);

It seems like you can also use the patch command. Put the diff in the root of the repository and run patch from the command line.

patch -i yourcoworkers.diff

or

patch -p0 -i yourcoworkers.diff

You may need to remove the leading folder structure if they created the diff without using --no-prefix.

If so, then you can remove the parts of the folder that don't apply using:

patch -p1 -i yourcoworkers.diff

The -p(n) signifies how many parts of the folder structure to remove.

More information on creating and applying patches here.

You can also use

git apply yourcoworkers.diff --stat 

to see if the diff by default will apply any changes. It may say 0 files affected if the patch is not applied correctly (different folder structure).

First, look here: http://en.wikipedia.org/wiki/List_of_unit_testing_frameworks#C

My company has a C library our customers use. We use CxxTest (a C++ unit test library) to test the code. CppUnit will also work. If you're stuck in C, I'd recommend RCUNIT (but CUnit is good too).

Given any arbitrary path string, various static methods on the System.IO.Path object give the following results.

strTestPath                 = C:\Users\DAG\Documents\Articles_2018\NTFS_File_Times_in_CMD\PathStringInfo.ps1
GetDirectoryName            = C:\Users\DAG\Documents\Articles_2018\NTFS_File_Times_in_CMD
GetFileName                 = PathStringInfo.ps1
GetExtension                = .ps1
GetFileNameWithoutExtension = PathStringInfo

Following is the code that generated the above output.

[console]::Writeline( "strTestPath                 = {0}{1}" ,
                      $strTestPath , [Environment]::NewLine );
[console]::Writeline( "GetDirectoryName            = {0}" ,
                      [IO.Path]::GetDirectoryName( $strTestPath ) );
[console]::Writeline( "GetFileName                 = {0}" ,
                      [IO.Path]::GetFileName( $strTestPath ) );
[console]::Writeline( "GetExtension                = {0}" ,
                      [IO.Path]::GetExtension( $strTestPath ) );
[console]::Writeline( "GetFileNameWithoutExtension = {0}" ,
                      [IO.Path]::GetFileNameWithoutExtension( $strTestPath ) );

Writing and testing the script that generated the above uncovered some quirks about how PowerShell differs from C#, C, C++, the Windows NT command scripting language, and just about everything else with which I have any experience.

You'll find the answer to your question in the help page for ?axis.

Here is one of the help page examples, modified with your data:

Option 1: use xaxp to define the axis labels

plot(x,y, xaxt="n")
axis(1, xaxp=c(10, 200, 19), las=2)

Option 2: Use at and seq() to define the labels:

plot(x,y, xaxt="n")
axis(1, at = seq(10, 200, by = 10), las=2)

Both these options yield the same graphic:

PS. Since you have a large number of labels, you'll have to use additional arguments to get the text to fit in the plot. I use las to rotate the labels.

You can use the following CSS for your input field:

.center-block {
  display: block;
  margin-right: auto;
  margin-left: auto;
}

Then,update your input field as following:

<input class="center-block" type="button" value="Some Button">

each JSF component renders itself out to HTML and has complete control over what HTML it produces. There are many tricks that can be used by JSF, and exactly which of those tricks will be used depends on the JSF implementation you are using.

• Ensure that every from input has a totaly unique name, so that when the form gets submitted back to to component tree that rendered it, it is easy to tell where each component can read its value form.
• The JSF component can generate javascript that submitts back to the serer, the generated javascript knows where each component is bound too, because it was generated by the component.

• For things like hlink you can include binding information in the url as query params or as part of the url itself or as matrx parameters. for examples.

  http:..../somelink?componentId=123 would allow jsf to look in the component tree to see that link 123 was clicked. or it could e htp:..../jsf;LinkId=123

The easiest way to answer this question is to create a JSF page with only one link, then examine the html output it produces. That way you will know exactly how this happens using the version of JSF that you are using.

1. Create an instance of Random class somewhere. Note that it's pretty important not to create a new instance each time you need a random number. You should reuse the old instance to achieve uniformity in the generated numbers. You can have a static field somewhere (be careful about thread safety issues):

   static Random rnd = new Random();
   

2. Ask the Random instance to give you a random number with the maximum of the number of items in the ArrayList:

   int r = rnd.Next(list.Count);
   

3. Display the string:

   MessageBox.Show((string)list[r]);
   

Although @Londo mentioned Scala's "s" string interpolator, I think Scala's "f" string interpolator is more relevant to the original question. The example used a few time in other responses could also be written (since Scala 2.10) this way:

scala> val name = "Ivan"
name: String = Ivan
scala> val thing = "Scala"
thing: String = Scala
scala> val formatted = f"Hello $name%s, isn't $thing%s cool?"
formatted: String = Hello Ivan, isn't Scala cool?

The connection to the original question is to be aware that:

• formatted is defined with a string that is prefixed with the letter "f". This is the "f" (formatting) string interpolator.
• The "f" string interpolator uses java.util.Formatter
• java.lang.String.format uses the same java.util.Formatter

The nice thing about string interpolation is that it lets you see which variable is being substituted directly into the string instead of having to match it with the arguments to the String.format method.

When you want to create an external_table, all field's name must be written in UPPERCASE.

Done.
