Use setResizable on your JFrame

yourFrame.setResizable(false);

But extending JFrame is generally a bad idea.

You could use getSelectedObjects() of ItemSelectable (superinterface of ButtonModel) which returns the list of selected items. In case of a radio button group it can only be one or none at all.

Why not use localStorage or any other way to set the value that you would like to pass?

That way you have access to it from anywhere!

By anywhere I mean within the given domain/context

Judging by your other post: How to Get the inner text of a span in PHP. You're quite new to web programming, and need to learn about the differences between code on the client (JavaScript) and code on the server (PHP).

As for the correct approach to grabbing the span text from the client I recommend Johns answer.

These are a good place to get started.

JavaScript: https://stackoverflow.com/questions/11246/best-resources-to-learn-javascript

PHP: https://stackoverflow.com/questions/772349/what-is-a-good-online-tutorial-for-php

Also I recommend using jQuery (Once you've got some JavaScript practice) it will eliminate most of the cross-browser compatability issues that you're going to have. But don't use it as a crutch to learn on, it's good to understand JavaScript too. http://jquery.com/

See the (quite) recent answer on the matplotlib repository, in which the following solution is suggested:

• If you want to set the xticklabels:

  ax.set_xticks([1,4,5]) 
  ax.set_xticklabels([1,4,5], fontsize=12)
  

• If you want to only increase the fontsize of the xticklabels, using the default values and locations (which is something I personally often need and find very handy):

  ax.tick_params(axis="x", labelsize=12) 
  

• To do it all at once:

  plt.setp(ax.get_xticklabels(), fontsize=12, fontweight="bold", 
           horizontalalignment="left")`
  

As of Node.js v6.0.0 using the constructor method has been deprecated and the following method should instead be used to construct a new buffer from a base64 encoded string:

var b64string = /* whatever */;
var buf = Buffer.from(b64string, 'base64'); // Ta-da

For Node.js v5.11.1 and below

Construct a new Buffer and pass 'base64' as the second argument:

var b64string = /* whatever */;
var buf = new Buffer(b64string, 'base64'); // Ta-da

If you want to be clean, you can check whether from exists :

if (typeof Buffer.from === "function") {
    // Node 5.10+
    buf = Buffer.from(b64string, 'base64'); // Ta-da
} else {
    // older Node versions, now deprecated
    buf = new Buffer(b64string, 'base64'); // Ta-da
}

Purge or Fix all of the invalid and expired provisioning profiles. Even though they appeared to be unrelated.

We encountered this when we attempted to recompile an app that was previously working fine. Nothing worked until we cleaned up the provisioning profiles.

Then click on "Download All" under the "Provisioning Profiles" area of the Apple Id account for the appropriate team.

Possibly related to XCode 7.3

You can solve this by increasing the maximum request length in your web.config:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <system.web>
        <httpRuntime maxRequestLength="102400" />
    </system.web>
</configuration>

The example above is for a 100Mb limit.

You have to change the file from .html to .php.

and add this following line

I had modified my answer tons of times and realized i don't have to say anything, python had explained itself already.

a = 'string'
a.replace('t', '_')
print(a)
>>> 'string'

a = a.replace('t', '_')
print(a)
>>> 's_ring'

b = 100
b + 1
print(b)
>>> 100

b = b + 1
print(b)
>>> 101

def test_id(arg):
    c = id(arg)
    arg = 123
    d = id(arg)
    return

a = 'test ids'
b = id(a)
test_id(a)
e = id(a)

# b = c  = e != d

# this function do change original value
del change_like_mutable(arg):
    arg.append(1)
    arg.insert(0, 9)
    arg.remove(2)
    return

test_1 = [1, 2, 3]
change_like_mutable(test_1)



# this function doesn't 
def wont_change_like_str(arg):
     arg = [1, 2, 3]
     return


test_2 = [1, 1, 1]
wont_change_like_str(test_2)
print("Doesn't change like a imutable", test_2)

This devil is not the reference / value / mutable or not / instance, name space or variable / list or str, IT IS THE SYNTAX, EQUAL SIGN.

You have to sort with a custom comparator based on the value of the entry. Then select all the keys before collecting

countByType.entrySet()
           .stream()
           .sorted((e1, e2) -> e1.getValue().compareTo(e2.getValue())) // custom Comparator
           .map(e -> e.getKey())
           .collect(Collectors.toList());

For some leanback (TV) emulators you can use cmd:

adb shell settings put global http_proxy 10.0.2.2:8888

• 8888 - is a port of proxy on a local machine (host), so on a local machine the http proxy will be 127.0.0.1:8888

To remove proxy (run sequentially in cmd line):

adb shell settings delete global http_proxy

adb shell settings put global global_http_proxy_host ""

adb shell settings put global global_http_proxy_port ""

You can use the apply function of the Series object:

>>> df = pd.DataFrame([['  a  ', 10], ['  c  ', 5]])
>>> df[0][0]
'  a  '
>>> df[0] = df[0].apply(lambda x: x.strip())
>>> df[0][0]
'a'

Note the usage of strip and not the regex which is much faster

Another option - use the apply function of the DataFrame object:

>>> df = pd.DataFrame([['  a  ', 10], ['  c  ', 5]])
>>> df.apply(lambda x: x.apply(lambda y: y.strip() if type(y) == type('') else y), axis=0)

   0   1
0  a  10
1  c   5

The print statement will call the write() method of any object you assign to sys.stdout.

I would spin up a small class to write to two places at once...

import sys

class Logger(object):
    def __init__(self):
        self.terminal = sys.stdout
        self.log = open("log.dat", "a")

    def write(self, message):
        self.terminal.write(message)
        self.log.write(message)  

sys.stdout = Logger()

Now the print statement will both echo to the screen and append to your log file:

# prints "1 2" to <stdout> AND log.dat
print "%d %d" % (1,2)

This is obviously quick-and-dirty. Some notes:

• You probably ought to parametize the log filename.
• You should probably revert sys.stdout to <stdout> if you won't be logging for the duration of the program.
• You may want the ability to write to multiple log files at once, or handle different log levels, etc.

These are all straightforward enough that I'm comfortable leaving them as exercises for the reader. The key insight here is that print just calls a "file-like object" that's assigned to sys.stdout.

For anyone that simply are looking to bypass the ERROR page to display the content on shared hosting. You might wanna try and use redirect in .htaccess file. If it is say 406 error, on UnoEuro it didn't seem to work simply deactivating the security. So I used this instead:

ErrorDocument 406 /

Then you can always change the error status using PHP. But be aware that in my case doing so means I am opening a door to SQL injections as I am bypassing WAF. So you will need to make sure that you either have your own security measures or enable the security again asap.

There is a much simpler way to do it using seaborn:

import seaborn as sns
from scipy.stats import norm

data = norm.rvs(5,0.4,size=1000) # you can use a pandas series or a list if you want

sns.distplot(data)
plt.show()

output:

Numbers inherit from the Number constructor which doesn't have the .toLowerCase method. You can look it up as a matter of fact:

"toLowerCase" in Number.prototype; // false

It seems that you are trying to call a method with a Map parameter. So, to call with an empty person name the right approach should be

HashMap<String, String> options = new HashMap<String, String>();
options.put("name", null);  
Person person = sample.searchPerson(options);

Or you can do it like this

HashMap<String, String> options = new HashMap<String, String>();
Person person = sample.searchPerson(options);

Using

Person person = sample.searchPerson(null);

Could get you a null pointer exception. It all depends on the implementation of searchPerson() method.

DECLARE @CodeNameString varchar(max)
SET @CodeNameString=''

SELECT @CodeNameString=@CodeNameString+CodeName FROM AccountCodes ORDER BY Sort
SELECT @CodeNameString

Following on @Arne Mertz's answer, as of C++11 std::ios_base::failure inherits from system_error (see http://www.cplusplus.com/reference/ios/ios_base/failure/), which contains both the error code and message that strerror(errno) would return.

std::ifstream f;

// Set exceptions to be thrown on failure
f.exceptions(std::ifstream::failbit | std::ifstream::badbit);

try {
    f.open(fileName);
} catch (std::system_error& e) {
    std::cerr << e.code().message() << std::endl;
}

This prints No such file or directory. if fileName doesn't exist.

UIActivityViewController Example Project

Set up your storyboard with two buttons and hook them up to your view controller (see code below).

Add an image to your Assets.xcassets. I called mine "lion".

Code

import UIKit
class ViewController: UIViewController {

    // share text
    @IBAction func shareTextButton(_ sender: UIButton) {

        // text to share
        let text = "This is some text that I want to share."

        // set up activity view controller
        let textToShare = [ text ]
        let activityViewController = UIActivityViewController(activityItems: textToShare, applicationActivities: nil)
        activityViewController.popoverPresentationController?.sourceView = self.view // so that iPads won't crash

        // exclude some activity types from the list (optional)
        activityViewController.excludedActivityTypes = [ UIActivityType.airDrop, UIActivityType.postToFacebook ]

        // present the view controller
        self.present(activityViewController, animated: true, completion: nil)

    }

    // share image
    @IBAction func shareImageButton(_ sender: UIButton) {

        // image to share
        let image = UIImage(named: "Image")

        // set up activity view controller
        let imageToShare = [ image! ]
        let activityViewController = UIActivityViewController(activityItems: imageToShare, applicationActivities: nil)
        activityViewController.popoverPresentationController?.sourceView = self.view // so that iPads won't crash

        // exclude some activity types from the list (optional)
        activityViewController.excludedActivityTypes = [ UIActivityType.airDrop, UIActivityType.postToFacebook ]

        // present the view controller
        self.present(activityViewController, animated: true, completion: nil)
    }

}

Result

Clicking "Share some text" gives result on the left and clicking "Share an image" gives the result on the right.

Notes

• I retested this with iOS 11 and Swift 4. I had to run it a couple times in the simulator before it worked because it was timing out. This may be because my computer is slow.
• If you wish to hide some of these choices, you can do that with excludedActivityTypes as shown in the code above.
• Not including the popoverPresentationController?.sourceView line will cause your app to crash when run on an iPad.
• This does not allow you to share text or images to other apps. You probably want UIDocumentInteractionController for that.

• Add sharing to your Swift app via UIActivityViewController
• UIActivity?View?Controller from NSHipster

Take a look at this project it outputs some interesting stats about keyspaces based on regexs and prefixes. It uses the DEBUG OBJECT command and scans the db, identifying groups of keys and estimating the percentage of space they're taking up.

https://github.com/snmaynard/redis-audit

Output looks like this:

Summary  

---------------------------------------------------+--------------+-------------------+---------------------------------------------------  
Key                                                | Memory Usage | Expiry Proportion | Last Access Time                                    
---------------------------------------------------+--------------+-------------------+---------------------------------------------------  
notification_3109439                               | 88.14%       | 0.0%              | 2 minutes                               
user_profile_3897016                               | 11.86%       | 99.98%            | 20 seconds  
---------------------------------------------------+--------------+-------------------+---------------------------------------------------  

Or this this one: https://github.com/sripathikrishnan/redis-rdb-tools which does a full analysis on the entire keyspace by analyzing a dump.rdb file offline. This one works well also. It can give you the avg/min/max size for the entries in your db, and will even do it based on a prefix.

If what you're really doing is manipulating a CSV file itself, Nelson's answer makes sense. However, my suspicion is that the CSV is simply an artifact of the problem you're solving. In C++, that probably means you have something like this as your data model:

struct Customer {
    int id;
    std::string first_name;
    std::string last_name;
    struct {
        std::string street;
        std::string unit;
    } address;
    char state[2];
    int zip;
};

Thus, when you're working with a collection of data, it makes sense to have std::vector<Customer> or std::set<Customer>.

With that in mind, think of your CSV handling as two operations:

// if you wanted to go nuts, you could use a forward iterator concept for both of these
class CSVReader {
public:
    CSVReader(const std::string &inputFile);
    bool hasNextLine();
    void readNextLine(std::vector<std::string> &fields);
private:
    /* secrets */
};
class CSVWriter {
public:
    CSVWriter(const std::string &outputFile);
    void writeNextLine(const std::vector<std::string> &fields);
private:
    /* more secrets */
};
void readCustomers(CSVReader &reader, std::vector<Customer> &customers);
void writeCustomers(CSVWriter &writer, const std::vector<Customer> &customers);

Read and write a single row at a time, rather than keeping a complete in-memory representation of the file itself. There are a few obvious benefits:

1. Your data is represented in a form that makes sense for your problem (customers), rather than the current solution (CSV files).
2. You can trivially add adapters for other data formats, such as bulk SQL import/export, Excel/OO spreadsheet files, or even an HTML <table> rendering.
3. Your memory footprint is likely to be smaller (depends on relative sizeof(Customer) vs. the number of bytes in a single row).
4. CSVReader and CSVWriter can be reused as the basis for an in-memory model (such as Nelson's) without loss of performance or functionality. The converse is not true.

Tortoise svn ->clean up

Thats all in SVN

I doubt there is one... It depends on browser, on printer (physical max dpi) and its driver, on paper size as you point out (and I might want to print on B5 paper too...), on settings (landscape or portrait?), plus you often can change the scale (percentage), etc.
Let the users tweak their settings...

Supervised learning can label a new item into one of the trained labels based on learning during training. You need to provide large numbers of training data set, validation data set and test data set. If you provide say pixel image vectors of digits along with training data with labels, then it can identify the numbers.

Unsupervised learning does not require training data-sets. In unsupervised learning it can group items into different clusters based on the difference in the input vectors. If you provide pixel image vectors of digits and ask it to classify into 10 categories, it may do that. But it does know how to labels it as you have not provided training labels.

A better way to write the async function would be by returning a pending Promise from the start and then handling both rejections and resolutions within the callback of the promise, rather than just spitting out a rejected promise on error. Example:

async foo(id: string): Promise<A> {
    return new Promise(function(resolve, reject) {
        // execute some code here
        if (success) { // let's say this is a boolean value from line above
            return resolve(success);
        } else {
            return reject(error); // this can be anything, preferably an Error object to catch the stacktrace from this function
        }
    });
}

Then you just chain methods on the returned promise:

async function bar () {
    try {
        var result = await foo("someID")
        // use the result here
    } catch (error) {
        // handle error here
    }
}

bar()

Firstly, do you really have to have a mutable struct? They're almost always a bad idea. Likewise public fields. There are some very occasional contexts in which they're reasonable (usually both parts together, as with ValueTuple) but they're pretty rare in my experience.

Other than that, I'd just create a constructor taking the two bits of data:

class SomeClass
{

    struct MyStruct
    {
        private readonly string label;
        private readonly int id;

        public MyStruct (string label, int id)
        {
            this.label = label;
            this.id = id;
        }

        public string Label { get { return label; } }
        public string Id { get { return id; } }

    }

    static readonly IList<MyStruct> MyArray = new ReadOnlyCollection<MyStruct>
        (new[] {
             new MyStruct ("a", 1),
             new MyStruct ("b", 5),
             new MyStruct ("q", 29)
        });
}

Note the use of ReadOnlyCollection instead of exposing the array itself - this will make it immutable, avoiding the problem exposing arrays directly. (The code show does initialize an array of structs - it then just passes the reference to the constructor of ReadOnlyCollection<>.)

If you just want to compare only two dates without time, then following code might help you:

final SimpleDateFormat dateFormat = new SimpleDateFormat("yyyyMMdd");
Date dLastUpdateDate = dateFormat.parse(20111116);
Date dCurrentDate = dateFormat.parse(dateFormat.format(new Date()));
if (dCurrentDate.after(dLastUpdateDate))
{
   add your logic
}

It depends on what you are doing. If you do a lot of 3D programming, knowledge of 3D geometry is certainly necessary, don't you agree? ;-) If you want to create a new image format like JPG or a new audio format like MP3, you are also pretty lost if you can't understand a cosine or fourier transformation, as these are the basics most lossy compression are based on. Many other problems can be resolved better if you know your math rather well.

There are also many other programming tasks you will find do not need much math.

I know this is an old post, but for anyone upgrading to Mountain Lion (10.8) and experiencing similar issues, adding FollowSymLinks to your {username}.conf file (in /etc/apache2/users/) did the trick for me. So the file looks like this:

<Directory "/Users/username/Sites/">
  Options Indexes MultiViews FollowSymLinks
  AllowOverride All
  Order allow,deny
  Allow from all
</Directory>

The localStorage and sessionStorage can only handle strings. You can extend the default storage-objects to handle arrays and objects. Just include this script and use the new methods:

Storage.prototype.setObj = function(key, obj) {
    return this.setItem(key, JSON.stringify(obj))
}
Storage.prototype.getObj = function(key) {
    return JSON.parse(this.getItem(key))
}

Use localStorage.setObj(key, value) to save an array or object and localStorage.getObj(key) to retrieve it. The same methods work with the sessionStorage object.

If you just use the new methods to access the storage, every value will be converted to a JSON-string before saving and parsed before it is returned by the getter.

Here is what I did to get a data set that included both the total and the number that met the criteria, within each shipping container. That let me answer the question "How many shipping containers have more than X% items over size 51"

select
   Schedule,
   PackageNum,
   COUNT (UniqueID) as Total,
   SUM (
   case
      when
         Size > 51 
      then
         1 
      else
         0 
   end
) as NumOverSize 
from
   Inventory 
where
   customer like '%PEPSI%' 
group by
   Schedule, PackageNum

Instead of trying to serve the node modules folder, you can also use Gulp to copy what you need to wwwroot.

Previous answers seem to be outdated.

Java's File.renameTo() is probably the easiest solution for API 7, and seems to work fine. Be carefull IT DOES NOT THROW EXCEPTIONS, but returns true/false!!!

Note that there seem to be problems with it in previous versions (same as NIO).

If you need to use a previous version, check here.

Here's an example for API7:

File f1= new File("C:\\Users\\.....\\foo");
File f2= new File("C:\\Users\\......\\foo.old");
System.err.println("Result of move:"+f1.renameTo(f2));

Alternatively:

System.err.println("Move:" +f1.toURI() +"--->>>>"+f2.toURI());
Path b1=Files.move(f1.toPath(),  f2.toPath(), StandardCopyOption.ATOMIC_MOVE ,StandardCopyOption.REPLACE_EXISTING ););
System.err.println("Move: RETURNS:"+b1);

If your code, if the user enters 'X' (for instance), when you reach the while condition evaluation it will determine that 'X' is differente from 'n' (nChar != 'n') which will make your loop condition true and execute the code inside of your loop. The second condition is not even evaluated.

Have a look at the jQuery UI vertical Tabs Docu. I try out it, it worked fine.

<style type="text/css">
/* Vertical Tabs
----------------------------------*/
.ui-tabs-vertical { width: 55em; }
.ui-tabs-vertical .ui-tabs-nav { padding: .2em .1em .2em .2em; float: left; width: 12em; }
.ui-tabs-vertical .ui-tabs-nav li { clear: left; width: 100%; border-bottom-width: 1px !important; border-right-width: 0 !important; margin: 0 -1px .2em 0; }
.ui-tabs-vertical .ui-tabs-nav li a { display:block; }
.ui-tabs-vertical .ui-tabs-nav li.ui-tabs-selected { padding-bottom: 0; padding-right: .1em; border-right-width: 1px; border-right-width: 1px; }
.ui-tabs-vertical .ui-tabs-panel { padding: 1em; float: right; width: 40em;}
</style> 

<script>
    $(document).ready(function() {
        $("#tabs").tabs().addClass('ui-tabs-vertical ui-helper-clearfix');
        $("#tabs li").removeClass('ui-corner-top').addClass('ui-corner-left');

    });
</script>

The rest of the sentence is:

where only structure (e.g., elements, comments, processing instructions, CDATA sections, and entity references) separates Text nodes, i.e., there are neither adjacent Text nodes nor empty Text nodes.

This basically means that the following XML element

<foo>hello 
wor
ld</foo>

could be represented like this in a denormalized node:

Element foo
    Text node: ""
    Text node: "Hello "
    Text node: "wor"
    Text node: "ld"

When normalized, the node will look like this

Element foo
    Text node: "Hello world"

And the same goes for attributes: <foo bar="Hello world"/>, comments, etc.

I suggest that

  Thread.dumpStack()

is an easier way and has the advantage of not actually constructing an exception or throwable when there may not be a problem at all, and is considerably more to the point.

Below is the solution in javascript language using ES6 syntax.

Stack.js

//stack using array
class Stack {
  constructor() {
    this.data = [];
  }

  push(data) {
    this.data.push(data);
  }

  pop() {
    return this.data.pop();
  }

  peek() {
    return this.data[this.data.length - 1];
  }

  size(){
    return this.data.length;
  }
}

export { Stack };

QueueUsingTwoStacks.js

import { Stack } from "./Stack";

class QueueUsingTwoStacks {
  constructor() {
    this.stack1 = new Stack();
    this.stack2 = new Stack();
  }

  enqueue(data) {
    this.stack1.push(data);
  }

  dequeue() {
    //if both stacks are empty, return undefined
    if (this.stack1.size() === 0 && this.stack2.size() === 0)
      return undefined;

    //if stack2 is empty, pop all elements from stack1 to stack2 till stack1 is empty
    if (this.stack2.size() === 0) {
      while (this.stack1.size() !== 0) {
        this.stack2.push(this.stack1.pop());
      }
    }

    //pop and return the element from stack 2
    return this.stack2.pop();
  }
}

export { QueueUsingTwoStacks };

Below is the usage:

index.js

import { StackUsingTwoQueues } from './StackUsingTwoQueues';

let que = new QueueUsingTwoStacks();
que.enqueue("A");
que.enqueue("B");
que.enqueue("C");

console.log(que.dequeue());  //output: "A"

Try java.lang.Instrumentation.getObjectSize(Object). But please be aware that

It returns an implementation-specific approximation of the amount of storage consumed by the specified object. The result may include some or all of the object's overhead, and thus is useful for comparison within an implementation but not between implementations. The estimate may change during a single invocation of the JVM.

There are many ways you can import Text file to the current sheet. Here are three (including the method that you are using above)

1. Using a QueryTable
2. Open the text file in memory and then write to the current sheet and finally applying Text To Columns if required.
3. If you want to use the method that you are currently using then after you open the text file in a new workbook, simply copy it over to the current sheet using Cells.Copy

Using a QueryTable

Here is a simple macro that I recorded. Please amend it to suit your needs.

Sub Sample()
    With ActiveSheet.QueryTables.Add(Connection:= _
        "TEXT;C:\Sample.txt", Destination:=Range("$A$1") _
        )
        .Name = "Sample"
        .FieldNames = True
        .RowNumbers = False
        .FillAdjacentFormulas = False
        .PreserveFormatting = True
        .RefreshOnFileOpen = False
        .RefreshStyle = xlInsertDeleteCells
        .SavePassword = False
        .SaveData = True
        .AdjustColumnWidth = True
        .RefreshPeriod = 0
        .TextFilePromptOnRefresh = False
        .TextFilePlatform = 437
        .TextFileStartRow = 1
        .TextFileParseType = xlDelimited
        .TextFileTextQualifier = xlTextQualifierDoubleQuote
        .TextFileConsecutiveDelimiter = False
        .TextFileTabDelimiter = True
        .TextFileSemicolonDelimiter = False
        .TextFileCommaDelimiter = True
        .TextFileSpaceDelimiter = False
        .TextFileColumnDataTypes = Array(1, 1, 1, 1, 1, 1)
        .TextFileTrailingMinusNumbers = True
        .Refresh BackgroundQuery:=False
    End With
End Sub

Open the text file in memory

Sub Sample()
    Dim MyData As String, strData() As String

    Open "C:\Sample.txt" For Binary As #1
    MyData = Space$(LOF(1))
    Get #1, , MyData
    Close #1
    strData() = Split(MyData, vbCrLf)
End Sub

Once you have the data in the array you can export it to the current sheet.

Using the method that you are already using

Sub Sample()
    Dim wbI As Workbook, wbO As Workbook
    Dim wsI As Worksheet

    Set wbI = ThisWorkbook
    Set wsI = wbI.Sheets("Sheet1") '<~~ Sheet where you want to import

    Set wbO = Workbooks.Open("C:\Sample.txt")

    wbO.Sheets(1).Cells.Copy wsI.Cells

    wbO.Close SaveChanges:=False
End Sub

FOLLOWUP

You can use the Application.GetOpenFilename to choose the relevant file. For example...

Sub Sample()
    Dim Ret

    Ret = Application.GetOpenFilename("Prn Files (*.prn), *.prn")

    If Ret <> False Then
        With ActiveSheet.QueryTables.Add(Connection:= _
        "TEXT;" & Ret, Destination:=Range("$A$1"))

            '~~> Rest of the code

        End With
    End If
End Sub

Assume a network environment where a "user" (aka you) has to logon. Usually this is a User ID (UID) and a Password (PW). OK then, what is your Identity, or who are you? You are the UID, and this gleans that "name" from your logon session. Simple! It should also work in an internet application that needs you to login, like Best Buy and others.

This will pull my UID, or "Name", from my session when I open the default page of the web application I need to use. Now, in my instance, I am part of a Domain, so I can use initial Windows authentication, and it needs to verify who I am, thus the 2nd part of the code. As for Forms Authentication, it would rely on the ticket (aka cookie most likely) sent to your workstation/computer. And the code would look like:

string id = HttpContext.Current.User.Identity.Name;

// Strip the domain off of the result
id = id.Substring(id.LastIndexOf(@"\", StringComparison.InvariantCulture) + 1);

Now it has my business name (aka UID) and can display it on the screen.

UPDATE t
SET cumulative_sum = (
 SELECT SUM(x.count)
 FROM t x
 WHERE x.id <= t.id
)

In case you closed multiple projects and trying to re-open all of them then in Windows->Show view-> Navigator

I was having the same problem with VS Code, turns out that enabling detection of Angular Icons fixes the problem

It is more efficient to send the files directly.

The base64 encoding of Content-Type: multipart/form-data adds an extra 33% overhead. If the server supports it, it is more efficient to send the files directly:

Doing Multiple $http.post Requests Directly from a FileList

$scope.upload = function(url, fileList) {
    var config = {
      headers: { 'Content-Type': undefined },
      transformResponse: angular.identity
    };
    var promises = fileList.map(function(file) {
      return $http.post(url, file, config);
    });
    return $q.all(promises);
};

When sending a POST with a File object, it is important to set 'Content-Type': undefined. The XHR send method will then detect the File object and automatically set the content type.

Working Demo of "select-ng-files" Directive that Works with ng-model¹

The <input type=file> element does not by default work with the ng-model directive. It needs a custom directive:

angular.module("app",[]);

angular.module("app").directive("selectNgFiles", function() {
  return {
    require: "ngModel",
    link: function postLink(scope,elem,attrs,ngModel) {
      elem.on("change", function(e) {
        var files = elem[0].files;
        ngModel.$setViewValue(files);
      })
    }
  }
});

<script src="//unpkg.com/angular/angular.js"></script>
  <body ng-app="app">
    <h1>AngularJS Input `type=file` Demo</h1>
    
    <input type="file" select-ng-files ng-model="fileList" multiple>
    
    <h2>Files</h2>
    <div ng-repeat="file in fileList">
      {{file.name}}
    </div>
  </body>

Second case is also inefficient in terms of String pool, you have to explicitly call intern() on return reference to make it intern.

Config->Apache->Open httpd.conf. search for Listen or 80,update listen port to 8081 save and restart server. Oh and shutdown Skype if you have it.

The window is the actual global object.

The screen is the screen, it contains properties about the user's display.

The document is where the DOM is.

Performance test:

http://jsperf.com/array-clear-methods/3

a = []; // 37% slower
a.length = 0; // 89% slower
a.splice(0, a.length)  // 97% slower
while (a.length > 0) {
    a.pop();
} // Fastest

Based on the absolutely brilliant @claviska solution, to whom all the credit is owed.

Full featured Bootstrap 4 file input with validation and help text.

Based on the input group example we have a dummy input text field used for displaying the filename to the user, which gets populated from the onchange event on the actual input file field hidden behind the label button. Aside from including the bootstrap 4 validation support we've also made it possible to click anywhere on the input to open the file dialog.

Three states of the file input

The three possible states are un-validated, valid and invalid with the dummy html input tag attribute required set.

Html markup for the input

We introduce only 2 custom classes input-file-dummy and input-file-btn to properly style and wire the desired behaviour. Everything else is standard Bootstrap 4 markup.

<div class="input-group">
  <input type="text" class="form-control input-file-dummy" placeholder="Choose file" aria-describedby="fileHelp" required>
  <div class="valid-feedback order-last">File is valid</div>
  <div class="invalid-feedback order-last">File is required</div>
  <label class="input-group-append mb-0">
    <span class="btn btn-primary input-file-btn">
      Browse… <input type="file" hidden>
    </span>
  </label>
</div>
<small id="fileHelp" class="form-text text-muted">Choose any file you like</small>

JavaScript behavioural provisions

The dummy input needs to be read only, as per the original example, to prevent the user from changing the input which may only be changed via the open file dialog. Unfortunately validation does not occur on readonly fields so we toggle the editability of the input on focus and blur ( jquery events onfocusin and onfocusout) and ensure that it becomes validatable again once a file is selected.

Aside from also making the text field clickable, by triggering the button's click event, the rest of the functionality of populating the dummy field was envisioned by @claviska.

$(function () {
  $('.input-file-dummy').each(function () {
    $($(this).parent().find('.input-file-btn input')).on('change', {dummy: this}, function(ev) {
      $(ev.data.dummy)
        .val($(this).val().replace(/\\/g, '/').replace(/.*\//, ''))
        .trigger('focusout');
    });
    $(this).on('focusin', function () {
        $(this).attr('readonly', '');
      }).on('focusout', function () {
        $(this).removeAttr('readonly');
      }).on('click', function () {
        $(this).parent().find('.input-file-btn').click();
      });
  });
});

Custom style tweaks

Most importantly we don't want the readonly field to jump between grey background and white so we ensure it stays white. The span button doesn't have a pointer cursor but we need to add one for the input anyway.

.input-file-dummy, .input-file-btn {
  cursor: pointer;
}
.input-file-dummy[readonly] {
  background-color: white;
}

nJoy!

Thanks RBarry. I'm putting together an IP block allocation system and storing as binary is the only way to go.

I'm storing the CIDR representation (ex: 192.168.1.0/24) of the IP block in a varchar field, and using 2 calculated fields to hold the binary form of the start and end of the block. From there, I can run fast queries to see if a given block as already been allocated or is free to assign.

I modified your function to calculate the ending IP Address like so:

CREATE FUNCTION dbo.fnDisplayIPv4End(@block AS VARCHAR(18)) RETURNS BINARY(4)
AS
BEGIN
    DECLARE @bin AS BINARY(4)
    DECLARE @ip AS VARCHAR(15)
    DECLARE @size AS INT

    SELECT @ip = Left(@block, Len(@block)-3)
    SELECT @size = Right(@block, 2)

    SELECT @bin = CAST( CAST( PARSENAME( @ip, 4 ) AS INTEGER) AS BINARY(1))
                + CAST( CAST( PARSENAME( @ip, 3 ) AS INTEGER) AS BINARY(1))
                + CAST( CAST( PARSENAME( @ip, 2 ) AS INTEGER) AS BINARY(1))
                + CAST( CAST( PARSENAME( @ip, 1 ) AS INTEGER) AS BINARY(1))

    SELECT @bin = CAST(@bin + POWER(2, 32-@size) AS BINARY(4))
    RETURN @bin
END;
go

I would open another terminal on your laptop and do the scp from there, since you already know how to set that connection up.

scp username@remotecomputer:/path/to/file/you/want/to/copy where/to/put/file/on/laptop

The username@remotecomputer is the same string you used with ssh initially.

SOAP uses WSDL for communication btw consumer and provider, whereas REST just uses XML or JSON to send and receive data

WSDL defines contract between client and service and is static by its nature. In case of REST contract is somewhat complicated and is defined by HTTP, URI, Media Formats and Application Specific Coordination Protocol. It's highly dynamic unlike WSDL.

SOAP doesn't return human readable result, whilst REST result is readable with is just plain XML or JSON

This is not true. Plain XML or JSON are not RESTful at all. None of them define any controls(i.e. links and link relations, method information, encoding information etc...) which is against REST as far as messages must be self contained and coordinate interaction between agent/client and service.

With links + semantic link relations clients should be able to determine what is next interaction step and follow these links and continue communication with service.

It is not necessary that messages be human readable, it's possible to use cryptic format and build perfectly valid REST applications. It doesn't matter whether message is human readable or not.

Thus, plain XML(application/xml) or JSON(application/json) are not sufficient formats for building REST applications. It's always reasonable to use subset of these generic media types which have strong semantic meaning and offer enough control information(links etc...) to coordinate interactions between client and server.

• For more details regarding control information I highly recommend to read this: http://www.amundsen.com/hypermedia/hfactor/
• Web Linking: http://tools.ietf.org/html/rfc5988
• Registered link relations: http://www.iana.org/assignments/link-relations/link-relations.xml

REST is over only HTTP

Not true, HTTP is most widely used and when we talk about REST web services we just assume HTTP. HTTP defines interface with it's methods(GET, POST, PUT, DELETE, PATCH etc) and various headers which can be used uniformly for interacting with resources. This uniformity can be achieved with other protocols as well.

P.S. Very simple, yet very interesting explanation of REST: http://www.looah.com/source/view/2284

Having had this same problem myself I'd like to post my perspective. I think that there are a couple motivating factors for doing something like this:

• You want to have some related enum codes, but in different classes. In my case I had a base class with several codes defined in an associated enum. At some later date (today!) I wanted to provide some new functionality to the base class, which also meant new codes for the enum.
• The derived class would support both the base classes' enum as well as its own. No duplicate enum values! So: how to have an enum for the subclass that includes the enum's of its parent along with its new values.

Using an interface doesn't really cut it: you can accidentally get duplicate enum values. Not desirable.

I ended up just combining the enums: this ensures that there cannot be any duplicate values, at the expense of being less tightly tied to its associated class. But, I figured the duplicate issue was my main concern...

The insertHtml() and insertText() methods will insert data into the editor window, adding to whatever is there already.

However, to replace the entire editor content, use setData().

SELECT CAST(DATEDIFF(S, '1970-01-01', SYSDATETIME()) AS BIGINT) * 1000

This does not give you full precision, but DATEDIFF(MS... causes overflow. If seconds are good enough, this should do it.

I had a problem with my AndroidManifest.xml file and the R.java was not generated.

I think the solution is to check ALL of your XML files, everywhere!

Tips and tricks

less

Why are you using editors to just look at a (large) file?

Under *nix or Cygwin, just use less. (There is a famous saying – "less is more, more or less" – because "less" replaced the earlier Unix command "more", with the addition that you could scroll back up.) Searching and navigating under less is very similar to Vim, but there is no swap file and little RAM used.

There is a Win32 port of GNU less. See the "less" section of the answer above.

Perl

Perl is good for quick scripts, and its .. (range flip-flop) operator makes for a nice selection mechanism to limit the crud you have to wade through.

For example:

$ perl -n -e 'print if ( 1000000 .. 2000000)' humongo.txt | less

This will extract everything from line 1 million to line 2 million, and allow you to sift the output manually in less.

Another example:

$ perl -n -e 'print if ( /regex one/ .. /regex two/)' humongo.txt | less

This starts printing when the "regular expression one" finds something, and stops when the "regular expression two" find the end of an interesting block. It may find multiple blocks. Sift the output...

logparser

This is another useful tool you can use. To quote the Wikipedia article:

logparser is a flexible command line utility that was initially written by Gabriele Giuseppini, a Microsoft employee, to automate tests for IIS logging. It was intended for use with the Windows operating system, and was included with the IIS 6.0 Resource Kit Tools. The default behavior of logparser works like a "data processing pipeline", by taking an SQL expression on the command line, and outputting the lines containing matches for the SQL expression.

Microsoft describes Logparser as a powerful, versatile tool that provides universal query access to text-based data such as log files, XML files and CSV files, as well as key data sources on the Windows operating system such as the Event Log, the Registry, the file system, and Active Directory. The results of the input query can be custom-formatted in text based output, or they can be persisted to more specialty targets like SQL, SYSLOG, or a chart.

Example usage:

C:\>logparser.exe -i:textline -o:tsv "select Index, Text from 'c:\path\to\file.log' where line > 1000 and line < 2000"
C:\>logparser.exe -i:textline -o:tsv "select Index, Text from 'c:\path\to\file.log' where line like '%pattern%'"

The relativity of sizes

100 MB isn't too big. 3 GB is getting kind of big. I used to work at a print & mail facility that created about 2% of U.S. first class mail. One of the systems for which I was the tech lead accounted for about 15+% of the pieces of mail. We had some big files to debug here and there.

And more...

Feel free to add more tools and information here. This answer is community wiki for a reason! We all need more advice on dealing with large amounts of data...

In WPF, you use a DispatcherTimer.

System.Windows.Threading.DispatcherTimer dispatcherTimer = new System.Windows.Threading.DispatcherTimer();
dispatcherTimer.Tick += new EventHandler(dispatcherTimer_Tick);
dispatcherTimer.Interval = new TimeSpan(0,5,0);
dispatcherTimer.Start();


private void dispatcherTimer_Tick(object sender, EventArgs e)
{
  // code goes here
}

DBeaver allows you connect to a DB2 database, run a query, and export the result-set to a CSV file that can be opened and fine-tuned in MS Excel or LibreOffice Calc.

To do this, all you have to do (in DBeaver) is right-click on the results grid (after running the query) and select "Export Resultset" from the context-menu.

This produces the dialog below, where you can ultimately save the result-set to a file as CSV, XML, or HTML:

We can use the below its very simple.

Date.ToString("yyyy-MM-dd");

Tried @hellslam's and @silverfighter's answers. I found a race condition holding my tests back. In my case I'm running mocha tests and in the before function of the test I want to erase the entire DB. Here's what works for me.

var con = mongoose.connect('mongodb://localhost/mydatabase');
mongoose.connection.on('open', function(){
    con.connection.db.dropDatabase(function(err, result){
        done();
    });
});

I had this issue after installing dotnetframework4.5.
Open path below:
"C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin" ( in 64 bits machine)
or
"C:\Program Files\Microsoft Visual Studio 10.0\VC\bin" (in 32 bits machine)
In this path find file cvtres.exe and rename it to cvtres1.exe then compile your project again.

The error means that R could not find the variable mentioned in the error message.

The easiest way to reproduce the error is to type the name of a variable that doesn't exist. (If you've defined x already, use a different variable name.)

x
## Error: object 'x' not found

The more complex version of the error has the same cause: calling a function when x does not exist.

mean(x)
## Error in mean(x) : 
##   error in evaluating the argument 'x' in selecting a method for function 'mean': Error: object 'x' not found

Once the variable has been defined, the error will not occur.

x <- 1:5
x
## [1] 1 2 3 4 5     
mean(x)
## [1] 3

You can check to see if a variable exists using ls or exists.

ls()        # lists all the variables that have been defined
exists("x") # returns TRUE or FALSE, depending upon whether x has been defined.

Errors like this can occur when you are using non-standard evaluation. For example, when using subset, the error will occur if a column name is not present in the data frame to subset.

d <- data.frame(a = rnorm(5))
subset(d, b > 0)
## Error in eval(expr, envir, enclos) : object 'b' not found

The error can also occur if you use custom evaluation.

get("var", "package:stats") #returns the var function
get("var", "package:utils")
## Error in get("var", "package:utils") : object 'var' not found

In the second case, the var function cannot be found when R looks in the utils package's environment because utils is further down the search list than stats.

In more advanced use cases, you may wish to read:

• The Scope section of the CRAN manual Intro to R and demo(scoping)
• The Non-standard evaluation chapter of Advanced R

if you just need it for db-related stuff, some OR Mappers (e.g. NHibernate) support transactinos out of the box per default.

Unless you are doing a DB to track historical times more than a century ago, using

Modified datetime DEFAULT ((0)) 

is perfectly safe and sound and allows more elegant queries than '1753-01-01' and more efficient queries than NULL.

However, since first Modified datetime is the time at which the record was inserted, you can use:

Modified datetime NOT NULL DEFAULT (GETUTCDATE())

which avoids the whole issue and makes your inserts easier and safer - as in you don't insert it at all and SQL does the housework :-)

With that in place you can still have elegant and fast queries by using 0 as a practical minimum since it's guranteed to always be lower than any insert-generated GETUTCDATE().

I'd agree inheritance is a better fit for the problem posed.

I found this question really handy though on decorating classes, thanks all.

Here's another couple of examples, based on other answers, including how inheritance affects things in Python 2.7, (and @wraps, which maintains the original function's docstring, etc.):

def dec(klass):
    old_foo = klass.foo
    @wraps(klass.foo)
    def decorated_foo(self, *args ,**kwargs):
        print('@decorator pre %s' % msg)
        old_foo(self, *args, **kwargs)
        print('@decorator post %s' % msg)
    klass.foo = decorated_foo
    return klass

@dec  # No parentheses
class Foo...

Often you want to add parameters to your decorator:

from functools import wraps

def dec(msg='default'):
    def decorator(klass):
        old_foo = klass.foo
        @wraps(klass.foo)
        def decorated_foo(self, *args ,**kwargs):
            print('@decorator pre %s' % msg)
            old_foo(self, *args, **kwargs)
            print('@decorator post %s' % msg)
        klass.foo = decorated_foo
        return klass
    return decorator

@dec('foo decorator')  # You must add parentheses now, even if they're empty
class Foo(object):
    def foo(self, *args, **kwargs):
        print('foo.foo()')

@dec('subfoo decorator')
class SubFoo(Foo):
    def foo(self, *args, **kwargs):
        print('subfoo.foo() pre')
        super(SubFoo, self).foo(*args, **kwargs)
        print('subfoo.foo() post')

@dec('subsubfoo decorator')
class SubSubFoo(SubFoo):
    def foo(self, *args, **kwargs):
        print('subsubfoo.foo() pre')
        super(SubSubFoo, self).foo(*args, **kwargs)
        print('subsubfoo.foo() post')

SubSubFoo().foo()

Outputs:

@decorator pre subsubfoo decorator
subsubfoo.foo() pre
@decorator pre subfoo decorator
subfoo.foo() pre
@decorator pre foo decorator
foo.foo()
@decorator post foo decorator
subfoo.foo() post
@decorator post subfoo decorator
subsubfoo.foo() post
@decorator post subsubfoo decorator

I've used a function decorator, as I find them more concise. Here's a class to decorate a class:

class Dec(object):

    def __init__(self, msg):
        self.msg = msg

    def __call__(self, klass):
        old_foo = klass.foo
        msg = self.msg
        def decorated_foo(self, *args, **kwargs):
            print('@decorator pre %s' % msg)
            old_foo(self, *args, **kwargs)
            print('@decorator post %s' % msg)
        klass.foo = decorated_foo
        return klass

A more robust version that checks for those parentheses, and works if the methods don't exist on the decorated class:

from inspect import isclass

def decorate_if(condition, decorator):
    return decorator if condition else lambda x: x

def dec(msg):
    # Only use if your decorator's first parameter is never a class
    assert not isclass(msg)

    def decorator(klass):
        old_foo = getattr(klass, 'foo', None)

        @decorate_if(old_foo, wraps(klass.foo))
        def decorated_foo(self, *args ,**kwargs):
            print('@decorator pre %s' % msg)
            if callable(old_foo):
                old_foo(self, *args, **kwargs)
            print('@decorator post %s' % msg)

        klass.foo = decorated_foo
        return klass

    return decorator

The assert checks that the decorator has not been used without parentheses. If it has, then the class being decorated is passed to the msg parameter of the decorator, which raises an AssertionError.

@decorate_if only applies the decorator if condition evaluates to True.

The getattr, callable test, and @decorate_if are used so that the decorator doesn't break if the foo() method doesn't exist on the class being decorated.

You need no sorted list. You need no sorting at all.

I need to add/remove keys from the list when object is added / removed from database.

But not immediately, the removal can wait. Use an ArrayList containing the ID's all alive objects plus at most some bounded percentage of deleted objects. Use a separate HashSet to keep track of deleted objects.

private List<ID> mostlyAliveIds = new ArrayList<>();
private Set<ID> deletedIds = new HashSet<>();

I want to randomly select few dozens of element from the whole list.

ID selectOne(Random random) {
    checkState(deletedIds.size() < mostlyAliveIds.size());
    while (true) {
        int index = random.nextInt(mostlyAliveIds.size());
        ID id = mostlyAliveIds.get(index);
        if (!deletedIds.contains(ID)) return ID;
    }
}

Set<ID> selectSome(Random random, int count) {
    checkArgument(deletedIds.size() <= mostlyAliveIds.size() - count);
    Set<ID> result = new HashSet<>();
    while (result.size() < count) result.add(selectOne(random));
}

For maintaining the data, do something like

void insert(ID id) {
    if (!deletedIds.remove(id)) mostlyAliveIds.add(ID);
} 

void delete(ID id) {
    if (!deletedIds.add(id)) {
         throw new ImpossibleException("Deleting a deleted element);
    }
    if (deletedIds.size() > 0.1 * mostlyAliveIds.size()) {
        mostlyAliveIds.removeAll(deletedIds);
        deletedIds.clear();
    }
}

The only tricky part is the insert which has to check if an already deleted ID was resurrected.

The delete ensures that no more than 10% of elements in mostlyAliveIds are deleted IDs. When this happens, they get all removed in one sweep (I didn't check the JDK sources, but I hope, they do it right) and the show goes on.

With no more than 10% of dead IDs, the overhead of selectOne is no more than 10% on the average.

I'm pretty sure that it's faster than any sorting as the amortized complexity is O(n).

Thank you Phil for your solution; in case someone ever gets in the same situation as me, here is a (more complex) variant:

---
# this is just to avoid a call to |default on each iteration
- set_fact:
    postconf_d: {}

- name: 'get postfix default configuration'
  command: 'postconf -d'
  register: command

# the answer of the command give a list of lines such as:
# "key = value" or "key =" when the value is null
- name: 'set postfix default configuration as fact'
  set_fact:
    postconf_d: >
      {{
        postconf_d |
        combine(
          dict([ item.partition('=')[::2]|map('trim') ])
        )
  with_items: command.stdout_lines

This will give the following output (stripped for the example):

"postconf_d": {
    "alias_database": "hash:/etc/aliases", 
    "alias_maps": "hash:/etc/aliases, nis:mail.aliases",
    "allow_min_user": "no", 
    "allow_percent_hack": "yes"
}

Going even further, parse the lists in the 'value':

- name: 'set postfix default configuration as fact'
  set_fact:
    postconf_d: >-
      {% set key, val = item.partition('=')[::2]|map('trim') -%}
      {% if ',' in val -%}
        {% set val = val.split(',')|map('trim')|list -%}
      {% endif -%}
      {{ postfix_default_main_cf | combine({key: val}) }}
  with_items: command.stdout_lines
...

"postconf_d": {
    "alias_database": "hash:/etc/aliases", 
    "alias_maps": [
        "hash:/etc/aliases", 
        "nis:mail.aliases"
    ], 
    "allow_min_user": "no", 
    "allow_percent_hack": "yes"
}

A few things to notice:

• in this case it's needed to "trim" everything (using the >- in YAML and -%} in Jinja), otherwise you'll get an error like:

  FAILED! => {"failed": true, "msg": "|combine expects dictionaries, got u\"  {u'...
  

• obviously the {% if .. is far from bullet-proof

• in the postfix case, val.split(',')|map('trim')|list could have been simplified to val.split(', '), but I wanted to point out the fact you will need to |list otherwise you'll get an error like:

  "|combine expects dictionaries, got u\"{u'...': <generator object do_map at ...
  

Hope this can help.

You are looking for variadic functions. printf() and sprintf() are variadic functions - they can accept a variable number of arguments.

This entails basically these steps:

1. The first parameter must give some indication of the number of parameters that follow. So in printf(), the "format" parameter gives this indication - if you have 5 format specifiers, then it will look for 5 more arguments (for a total of 6 arguments.) The first argument could be an integer (eg "myfunction(3, a, b, c)" where "3" signifies "3 arguments)

2. Then loop through and retrieve each successive argument, using the va_start() etc. functions.

There are plenty of tutorials on how to do this - good luck!

My which pip shows the following path:

$ which pip
/home/kmario23/anaconda3/bin/pip

So, whatever package I install using pip install <package-name> will have to be reflected in the list of packages when the list is exported using:

$ conda list --export > conda_list.txt

But, I don't. So, instead I used the following command as suggested by several others:

# get environment name by
$ conda-env list

# get list of all installed packages by (conda, pip, etc.,)
$ conda-env export -n <my-environment-name> > all_packages.yml
# if you haven't created any specific env, then just use 'root'

Now, I can see all the packages in my all-packages.yml file.

First thing to do is run this:

SHOW GRANTS;

You will quickly see you were assigned the anonymous user to authenticate into mysql.

Instead of logging into mysql with

mysql

login like this:

mysql -uroot

By default, root@localhost has all rights and no password.

If you cannot login as root without a password, do the following:

Step 01) Add the two options in the mysqld section of my.ini:

[mysqld]
skip-grant-tables
skip-networking

Step 02) Restart mysql

net stop mysql
<wait 10 seconds>
net start mysql

Step 03) Connect to mysql

mysql

Step 04) Create a password from root@localhost

UPDATE mysql.user SET password=password('whateverpasswordyoulike')
WHERE user='root' AND host='localhost';
exit

Step 05) Restart mysql

net stop mysql
<wait 10 seconds>
net start mysql

Step 06) Login as root with password

mysql -u root -p

You should be good from there.

CAVEAT: Please remove anonymous users !!!

I ran some tests (on postgres 9.5) using two tables with ~2M rows each. This query below performed at least 5* better than the other queries proposed:

-- Count
SELECT count(*) FROM (
    (SELECT id FROM table1) EXCEPT (SELECT id FROM table2)
) t1_not_in_t2;

-- Get full row
SELECT table1.* FROM (
    (SELECT id FROM table1) EXCEPT (SELECT id FROM table2)
) t1_not_in_t2 JOIN table1 ON t1_not_in_t2.id=table1.id;

PowerShell has a cmdlet for this called Measure-Command. You'll have to ensure that PowerShell is available on the machine that runs it.

PS> Measure-Command { echo hi }

Days              : 0
Hours             : 0
Minutes           : 0
Seconds           : 0
Milliseconds      : 0
Ticks             : 1318
TotalDays         : 1.52546296296296E-09
TotalHours        : 3.66111111111111E-08
TotalMinutes      : 2.19666666666667E-06
TotalSeconds      : 0.0001318
TotalMilliseconds : 0.1318

Measure-Command captures the command's output. You can redirect the output back to your console using Out-Default:

PS> Measure-Command { echo hi | Out-Default }
hi

Days              : 0
...

Measure-Command returns a TimeSpan object, so the measured time is printed as a bunch of fields. You can format the object into a timestamp string using ToString():

PS> (Measure-Command { echo hi | Out-Default }).ToString()
hi
00:00:00.0001318

If the command inside Measure-Command changes your console text color, use [Console]::ResetColor() to reset it back to normal.

Here is a simple letter-range implementation:

Code

def letter_range(start, stop="{", step=1):
    """Yield a range of lowercase letters.""" 
    for ord_ in range(ord(start.lower()), ord(stop.lower()), step):
        yield chr(ord_)

Demo

list(letter_range("a", "f"))
# ['a', 'b', 'c', 'd', 'e']

list(letter_range("a", "f", step=2))
# ['a', 'c', 'e']

def filter_out_colors(elements):
  colors = ['red', 'green']
  result = []
  for element in elements:
    if element in colors:
       continue # skip the element
    # You can do whatever here
    result.append(element)
  return result

  >>> filter_out_colors(['lemon', 'orange', 'red', 'pear'])
  ['lemon', 'orange', 'pear']

host or hostname would be the i.p address of the remote server, or if you can access it over the network by computer name, that should work to.

I use this function to calculate cpu usage. Hope it can help you.

private float readUsage() {
    try {
        RandomAccessFile reader = new RandomAccessFile("/proc/stat", "r");
        String load = reader.readLine();

        String[] toks = load.split(" +");  // Split on one or more spaces

        long idle1 = Long.parseLong(toks[4]);
        long cpu1 = Long.parseLong(toks[2]) + Long.parseLong(toks[3]) + Long.parseLong(toks[5])
              + Long.parseLong(toks[6]) + Long.parseLong(toks[7]) + Long.parseLong(toks[8]);

        try {
            Thread.sleep(360);
        } catch (Exception e) {}

        reader.seek(0);
        load = reader.readLine();
        reader.close();

        toks = load.split(" +");

        long idle2 = Long.parseLong(toks[4]);
        long cpu2 = Long.parseLong(toks[2]) + Long.parseLong(toks[3]) + Long.parseLong(toks[5])
            + Long.parseLong(toks[6]) + Long.parseLong(toks[7]) + Long.parseLong(toks[8]);

        return (float)(cpu2 - cpu1) / ((cpu2 + idle2) - (cpu1 + idle1));

    } catch (IOException ex) {
        ex.printStackTrace();
    }

    return 0;
} 

UTF-8 and UCS-2/UTF-16 can be distinguished reasonably easily via a byte order mark at the start of the file. If this exists then it's a pretty good bet that the file is in that encoding - but it's not a dead certainty. You may well also find that the file is in one of those encodings, but doesn't have a byte order mark.

I don't know much about ISO-8859-2, but I wouldn't be surprised if almost every file is a valid text file in that encoding. The best you'll be able to do is check it heuristically. Indeed, the Wikipedia page talking about it would suggest that only byte 0x7f is invalid.

There's no idea of reading a file "as it is" and yet getting text out - a file is a sequence of bytes, so you have to apply a character encoding in order to decode those bytes into characters.

The thing is that your ajax response is returning a string, so if you use directly $(response) it would return JQUERY: Uncaught Error: Syntax error, unrecognized expression in the console. In order to use it properly you need to use first a JQUERY built-in function called $.parseHTML(response). As what the function name implies you need to parse the string first as an html object. Just like this in your case:

$.ajax({
    url: url, 
    cache: false,
    success: function(response) {
        var parsedResponse = $.parseHTML(response);
        var result = $(parsedResponse).find("#result");

        alert(response); // returns as string in console
        alert(parsedResponse); // returns as object HTML in console
        alert(result); // returns as object that has an id named result 
    }
});

answer suggested by rakesh is great but still with some discription Singleton in Android is the same as Singleton in Java: The Singleton design pattern addresses all of these concerns. With the Singleton design pattern you can:

1) Ensure that only one instance of a class is created

2) Provide a global point of access to the object

3) Allow multiple instances in the future without affecting a singleton class's clients

A basic Singleton class example:

public class MySingleton
{
    private static MySingleton _instance;

    private MySingleton()
    {

    }

    public static MySingleton getInstance()
    {
        if (_instance == null)
        {
            _instance = new MySingleton();
        }
        return _instance;
    }
}

While other answers already fulfilled the question (it's a 3 years old question after all), I'm just gonna add some info, and probably fixed a bit of misunderstanding.

Em, while originally meant as the term for a single 'M' character's width in typography, in digital medium it was shifted to a unit relative to the point size of the typeface (font-size or textSize), in other words it's uses the height of the text, not the width of a single 'M'.

In Android, that means when you specify the ems of a TextView, it uses the said TextView's textSize as the base, excluding the added padding for accents/diacritics. When you set a 16sp TextView's ems to 4, it means its width will be 64sp wide, thus explained @stefan 's comment about why a 10 ems wide EditText is able to fit 17 'M'.

In the nav go View => Layout => Columns:2 (alt+shift+2) and open your file again in the other pane (i.e. click the other pane and use ctrl+p filename.py)

It appears you can also reopen the file using the command File -> New View into File which will open the current file in a new tab

I don't think they are reprinting paper books each year. The copyright of the year when the book was printed is valid in all next years.

The same principle should apply to web pages, too. However "the year when website was created" is a bit different. So, if you make changes to your web site - you are not done yet. Hence, when updating the site, you may want to update the copyright year.

Modify onClick() as follows:

@Override
public void onClick(View v) {
    if(v == btn) {
        canvas=sv.getHolder().lockCanvas();
        if(canvas!=null) {
            canvas.drawBitmap(bitmap, 100, 100, null);
            sv.getHolder().unlockCanvasAndPost(canvas);
        }
    } else if(v == btn1) {
        saveBitmapToInternalStorage(bitmap);
    }
}

There are several ways to enforce that btn must be pressed before btn1 so that the bitmap is painted before you attempt to save it.

I suggest that you initially disable btn1, and that you enable it when btn is clicked, like this:

if(v == btn) {
    ...
    btn1.setEnabled(true);
}

It is cumbersome to interoperate socket.io and connect sessions support. The problem is not because socket.io "hijacks" request somehow, but because certain socket.io transports (I think flashsockets) don't support cookies. I could be wrong with cookies, but my approach is the following:

1. Implement a separate session store for socket.io that stores data in the same format as connect-redis
2. Make connect session cookie not http-only so it's accessible from client JS
3. Upon a socket.io connection, send session cookie over socket.io from browser to server
4. Store the session id in a socket.io connection, and use it to access session data from redis.

The Sortable JS library is compatible with touch screens and does not require jQuery.

The way it handles touch screens it that you need to touch the screen for about 1 second to start dragging an item.

Also, they present a video test showing that this library is running faster than JQuery UI Sortable.

We've solved this, although we didn't think having the addListener outside of the for would make any difference, it seems to. Here's the answer:

Create a new function with your information for the infoWindow in it:

function addInfoWindow(marker, message) {

            var infoWindow = new google.maps.InfoWindow({
                content: message
            });

            google.maps.event.addListener(marker, 'click', function () {
                infoWindow.open(map, marker);
            });
        }

Then call the function with the array ID and the marker you want to create:

addInfoWindow(marker, hotels[i][3]);

getJSONArray(attrname) will get you an array from the object of that given attribute name in your case what is happening is that for

{"abridged_cast":["name": blah...]}
^ its trying to search for a value "characters"

but you need to get into the array and then do a search for "characters"

try this

String json="{'abridged_cast':[{'name':'JeffBridges','id':'162655890','characters':['JackPrescott']},{'name':'CharlesGrodin','id':'162662571','characters':['FredWilson']},{'name':'JessicaLange','id':'162653068','characters':['Dwan']},{'name':'JohnRandolph','id':'162691889','characters':['Capt.Ross']},{'name':'ReneAuberjonois','id':'162718328','characters':['Bagley']}]}";

    JSONObject jsonResponse;
    try {
        ArrayList<String> temp = new ArrayList<String>();
        jsonResponse = new JSONObject(json);
        JSONArray movies = jsonResponse.getJSONArray("abridged_cast");
        for(int i=0;i<movies.length();i++){
            JSONObject movie = movies.getJSONObject(i);
            JSONArray characters = movie.getJSONArray("characters");
            for(int j=0;j<characters.length();j++){
                temp.add(characters.getString(j));
            }
        }
        Toast.makeText(this, "Json: "+temp, Toast.LENGTH_LONG).show();
    } catch (JSONException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();

grep -n "YOUR SEARCH STRING" * > output-file

The -n will print the line number and the > will redirect grep-results to the output-file.
If you want to "clean" the results you can filter them using pipe | for example:
grep -n "test" * | grep -v "mytest" > output-file will match all the lines that have the string "test" except the lines that match the string "mytest" (that's the switch -v) - and will redirect the result to an output file.
A few good grep-tips can be found on this post

@reannual's answer works well, but there's an issue with it: os.popen is now deprecated. The subprocess module should be used instead, so here's a version of @reannual's code that uses subprocess and directly answers the question (by giving the column width directly as an int:

import subprocess

columns = int(subprocess.check_output(['stty', 'size']).split()[1])

Since originally writing this answer, a new specification has reached recommendation status thanks to the W3C. The Page Visibility API (on MDN) now allows us to more accurately detect when a page is hidden to the user.

document.addEventListener("visibilitychange", onchange);

Current browser support:

• Chrome 13+
• Internet Explorer 10+
• Firefox 10+
• Opera 12.10+ ^{[read notes]}

The following code falls back to the less reliable blur/focus method in incompatible browsers:

(function() {
  var hidden = "hidden";

  // Standards:
  if (hidden in document)
    document.addEventListener("visibilitychange", onchange);
  else if ((hidden = "mozHidden") in document)
    document.addEventListener("mozvisibilitychange", onchange);
  else if ((hidden = "webkitHidden") in document)
    document.addEventListener("webkitvisibilitychange", onchange);
  else if ((hidden = "msHidden") in document)
    document.addEventListener("msvisibilitychange", onchange);
  // IE 9 and lower:
  else if ("onfocusin" in document)
    document.onfocusin = document.onfocusout = onchange;
  // All others:
  else
    window.onpageshow = window.onpagehide
    = window.onfocus = window.onblur = onchange;

  function onchange (evt) {
    var v = "visible", h = "hidden",
        evtMap = {
          focus:v, focusin:v, pageshow:v, blur:h, focusout:h, pagehide:h
        };

    evt = evt || window.event;
    if (evt.type in evtMap)
      document.body.className = evtMap[evt.type];
    else
      document.body.className = this[hidden] ? "hidden" : "visible";
  }

  // set the initial state (but only if browser supports the Page Visibility API)
  if( document[hidden] !== undefined )
    onchange({type: document[hidden] ? "blur" : "focus"});
})();

onfocusin and onfocusout are required for IE 9 and lower, while all others make use of onfocus and onblur, except for iOS, which uses onpageshow and onpagehide.

“GCC” is a common shorthand term for the GNU Compiler Collection. This is both the most general name for the compiler, and the name used when the emphasis is on compiling C programs (as the abbreviation formerly stood for “GNU C Compiler”).

When referring to C++ compilation, it is usual to call the compiler “G++”. Since there is only one compiler, it is also accurate to call it “GCC” no matter what the language context; however, the term “G++” is more useful when the emphasis is on compiling C++ programs.

For overlapping count we can use use:

def count_substring(string, sub_string):
    count=0
    beg=0
    while(string.find(sub_string,beg)!=-1) :
        count=count+1
        beg=string.find(sub_string,beg)
        beg=beg+1
    return count

For non-overlapping case we can use count() function:

string.count(sub_string)

Here is the code:

<?php
 session_start();
 session_destroy();
?>

When the session has started, the session for the last/current user has been started, so don't need to declare the username. It will be deleted automatically by the session_destroy method.

Create a class like this:

public class Data
{
    public string Id {get; set;}
    public string Name {get; set;}
    public string First_Name {get; set;}
    public string Last_Name {get; set;}
    public string Username {get; set;}
    public string Gender {get; set;}
    public string Locale {get; set;}
}

(I'm not 100% sure, but if that doesn't work you'll need use [DataContract] and [DataMember] for DataContractJsonSerializer.)

Then create JSonSerializer:

private static readonly XmlObjectSerializer Serializer = new DataContractJsonSerializer(typeof(Data));

and deserialize object:

// convert string to stream
byte[] byteArray = Encoding.UTF8.GetBytes(contents);
using(var stream = new MemoryStream(byteArray))
{
    (Data)Serializer.ReadObject(stream);
}

You can turn the color picker into an application by following the guide here:

http://hints.macworld.com/article.php?story=20060408050920158

From the guide:

Simply fire up AppleScript (Applications -> AppleScript Editor) and enter this text:

choose color

Now, save it as an application (File -> Save As, and set the File Format pop-up to Application), and you're done

If you use gradle build, use this: BuildConfig.APPLICATION_ID to get the package name of the application.

This answer uses the jQuery UI Datepicker, which is a separate include. There are other ways to do this without including jQuery UI.

First, you simply need to add the datepicker class to the textbox, in addition to form-control:

<div class="form-group input-group-sm">
    @Html.LabelFor(model => model.DropOffDate)
    @Html.TextBoxFor(model => model.DropOffDate, new { @class = "form-control datepicker", placeholder = "Enter Drop-off date here..." })
    @Html.ValidationMessageFor(model => model.DropOffDate)
</div>

Then, to be sure the javascript is triggered after the textbox is rendered, you have to put the datepicker call in the jQuery ready function:

<script type="text/javascript">
    $(function () { // will trigger when the document is ready
       $('.datepicker').datepicker(); //Initialise any date pickers
    });
</script>

For anyone who is looking to enable this on the Mac version, it is not available. Developers of Visual Studio stated they will include in their roadmap.

Here's the list of all Win32 error codes. You can use this page to lookup the error code mentioned in IIS logs:
http://msdn.microsoft.com/en-us/library/ms681381.aspx

You can also use command line utility net to find information about a Win32 error code. The syntax would be:
net helpmsg Win32_Status_Code

You shouldn´t use client javascript to access databases for several reasons (bad practice, security issues, etc) but if you really want to do this, here is an example:

var connection = new ActiveXObject("ADODB.Connection") ;

var connectionstring="Data Source=<server>;Initial Catalog=<catalog>;User ID=<user>;Password=<password>;Provider=SQLOLEDB";

connection.Open(connectionstring);
var rs = new ActiveXObject("ADODB.Recordset");

rs.Open("SELECT * FROM table", connection);
rs.MoveFirst
while(!rs.eof)
{
   document.write(rs.fields(1));
   rs.movenext;
}

rs.close;
connection.close; 

A better way to connect to a sql server would be to use some server side language like PHP, Java, .NET, among others. Client javascript should be used only for the interfaces.

And there are rumors of an ancient legend about the existence of server javascript, but this is another story. ;)

PSH> $cred = Get-Credential

PSH> $cred | Export-CliXml c:\temp\cred.clixml

PSH> $cred2 = Import-CliXml c:\temp\cred.clixml

That hashes it against your SID and the machine's SID, so the file is useless on any other machine, or in anyone else's hands.

Anonymous ftp logins are usually the username 'anonymous' with the user's email address as the password. Some servers parse the password to ensure it looks like an email address.

User:  anonymous
Password:  [email protected]

The Collection interface includes the toArray() method to convert a new collection into an array. There are two forms of this method. The no argument version will return the elements of the collection in an Object array: public Object[ ] toArray(). The returned array cannot cast to any other data type. This is the simplest version. The second version requires you to pass in the data type of the array you’d like to return: public Object [ ] toArray(Object type[ ]).

 public static void main(String[] args) {  
           List<String> l=new ArrayList<String>();  
           l.add("A");  
           l.add("B");  
           l.add("C");  
           Object arr[]=l.toArray();  
           for(Object a:arr)  
           {  
                String str=(String)a;  
                System.out.println(str);  
           }  
      }

Addition to the accepted answer:

if you are going to use

 @Html.ActionLink("LinkName", "ActionName", "ControllerName", new { @id = idValue, @secondParam= = 2 },null)

this will create actionlink where you can't create new custom attribute or style for the link.

However, the 4th parameter in ActionLink extension will solve that problem. Use the 4th parameter for customization in your way.

 @Html.ActionLink("LinkName", "ActionName", "ControllerName", new { @id = idValue, @secondParam= = 2 }, new { @class = "btn btn-info", @target = "_blank" })

you must do 4 following step :

1. create event

   var event = new Event("change",{
       detail: {
           oldValue:yourValueVariable,
           newValue:!yourValueVariable
       },
       bubbles: true,
       cancelable: true
   });
   event.simulated = true;
   let tracker = this.yourComponentDomRef._valueTracker;
   if (tracker) {
       tracker.setValue(!yourValueVariable);
   }
   

2. bind value to component dom

   this.yourComponentDomRef.value = !yourValueVariable;
   

3. bind element onchange to react onChange function

    this.yourComponentDomRef.onchange = (e)=>this.props.onChange(e);
   

4. dispatch event

   this.yourComponentDomRef.dispatchEvent(event);
   

in above code yourComponentDomRef refer to master dom of your React component for example <div className="component-root-dom" ref={(dom)=>{this.yourComponentDomRef= dom}}>

Why do you want to load a 4+ GB file into memory? Even if you find a text editor that can do that, does your machine have 4 GB of memory? And unless it has a lot more than 4 GB in physical memory, your machine will slow down a lot and go swap file crazy.

So why do you want a 4+ GB file? If you want to transform it, or do a search and replace, you may be better off writing a small quick program to do it.

This regex is very short and sweet for working.

/^([+]\d{2})?\d{10}$/

Ex: +910123456789 or 0123456789

-> /^ and $/ is for starting and ending
-> The ? mark is used for conditional formatting where before question mark is available or not it will work
-> ([+]\d{2}) this indicates that the + sign with two digits '\d{2}' here you can place digit as per country
-> after the ? mark '\d{10}' this says that the digits must be 10 of length change as per your country mobile number length

This is how this regex for mobile number is working.
+ sign is used for world wide matching of number.

if you want to add the space between than you can use the

[ ]

here the square bracket represents the character sequence and a space is character for searching in regex.
for the space separated digit you can use this regex

/^([+]\d{2}[ ])?\d{10}$/

Ex: +91 0123456789

Thanks ask any question if you have.

Archive.bulk is now deprecated, the new method to be used for this is glob:

var fileName =   'zipOutput.zip'
var fileOutput = fs.createWriteStream(fileName);

fileOutput.on('close', function () {
    console.log(archive.pointer() + ' total bytes');
    console.log('archiver has been finalized and the output file descriptor has closed.');
});

archive.pipe(fileOutput);
archive.glob("../dist/**/*"); //some glob pattern here
archive.glob("../dist/.htaccess"); //another glob pattern
// add as many as you like
archive.on('error', function(err){
    throw err;
});
archive.finalize();

I was having the same problem, none of the posted solutions helped. Finally, I figured out what I was doing wrong. When I installed the Java JDK it asked me for a directiy where I wanted to install. I changed the directory to where I wanted the code to go. It then asked for a directory where it could install the Runtime Environment and I selected the SAME DIRECTORY where I installed the JDK. It over wrote my lib folder and erased the tools.jar. Be sure to use different folders during the install. I used my custom folder for the JDK and the default folder for the RE and everything worked fine.

just add

android:gravity="center"

and done :)

Yes, you can disable it using html.
Just add oncontextmenu="return false;" on your body or element.
It is very simple and just uses valid HTML, no jQuery or JS.

CLOB are like Files, you can read parts of it easily like this

// read the first 1024 characters
String str = myClob.getSubString(0, 1024);

and you can overwrite to it like this

// overwrite first 1024 chars with first 1024 chars in str
myClob.setString(0, str,0,1024);

I don't suggest using StringBuilder and fill it until you get an Exception, almost like adding numbers blindly until you get an overflow. Clob is like a text file and the best way to read it is using a buffer, in case you need to process it, otherwise you can stream it into a local file like this

int s = 0;
File f = new File("out.txt");
FileWriter fw new FileWriter(f);

while (s < myClob.length())
{
    fw.write(myClob.getSubString(0, 1024));
    s += 1024;
}

fw.flush();
fw.close();

Diffuse is also very good. It even lets you easily adjust how lines are matched up, by defining match-points.

Based on your requirement i think you are wanted to put dynamic fields in CSS file, however that is not possible as CSS is a static language. However you can simulate the behaviour by using Angular.

Please refer to the below example. I'm here showing only one component.

login.component.html

import { Component, OnInit } from '@angular/core';
import { DomSanitizer } from '@angular/platform-browser';

    @Component({
      selector: 'app-login',
      templateUrl: './login.component.html',
      styleUrls: ['./login.component.css']
    })
    export class LoginComponent implements OnInit {

      cssProperty:any;
      constructor(private sanitizer: DomSanitizer) { 
        console.log(window.innerWidth);
        console.log(window.innerHeight);
        this.cssProperty = 'position:fixed;top:' + Math.floor(window.innerHeight/3.5) + 'px;left:' + Math.floor(window.innerWidth/3) + 'px;';
        this.cssProperty = this.sanitizer.bypassSecurityTrustStyle(this.cssProperty);
      }

    ngOnInit() {

      }

    }

login.component.ts

<div class="home">
    <div class="container" [style]="cssProperty">
        <div class="card">
            <div class="card-header">Login</div>
            <div class="card-body">Please login</div>
            <div class="card-footer">Login</div>
        </div>
    </div>
</div>

login.component.css

.card {
    max-width: 400px;
}
.card .card-body {
    min-height: 150px;
}
.home {
    background-color: rgba(171, 172, 173, 0.575);
}

Why complicate things when it can be done with simple jQuery like following.

$('#myModal').on('shown.bs.modal', function (e) {
    console.log('myModal is shown');
    // Your actual function here
})

I typically bind this data using the RowDatabound event with the GridView:

protected void FormatGridView(object sender, System.Web.UI.WebControls.GridViewRowEventArgs e)
{
   if (e.Row.RowType == DataControlRowType.DataRow) 
   {
      ((Button)e.Row.Cells(0).FindControl("btnSpecial")).CommandArgument = e.Row.RowIndex.ToString();
   }
}

Allocate memory before using the pointer. If you don't allocate memory *point = 12 is undefined behavior.

int *fun()
{
    int *point = malloc(sizeof *point); /* Mandatory. */
    *point=12;  
    return point;
}

Also your printf is wrong. You need to dereference (*) the pointer.

printf("%d", *ptr);
             ^

You should probably stop using launch images in iOS 8 and use a storyboard or nib/xib.

• In Xcode 6, open the File menu and choose New ? File... ? iOS ? User Interface ? Launch Screen.

• Then open the settings for your project by clicking on it.

• In the General tab, in the section called App Icons and Launch Images, set the Launch Screen File to the files you just created (this will set UILaunchStoryboardName in info.plist).

Note that for the time being the simulator will only show a black screen, so you need to test on a real device.

Adding a Launch Screen xib file to your project:

Configuring your project to use the Launch Screen xib file instead of the Asset Catalog:

if you provide a bad path or a broken link, if the compiler cannot find the image, the picture box would display an X icon on its body.

PictureBox picture = new PictureBox
        {
            Name = "pictureBox",
            Size = new Size(100, 50),
            Location = new Point(14, 17),
            Image = Image.FromFile(@"c:\Images\test.jpg"),
            SizeMode = PictureBoxSizeMode.CenterImage
        };
p.Controls.Add(picture);

OR

PictureBox picture = new PictureBox
        {
            Name = "pictureBox",
            Size = new Size(100, 50),
            Location = new Point(14, 17),
            ImageLocation = @"c:\Images\test.jpg",
            SizeMode = PictureBoxSizeMode.CenterImage
        };
p.Controls.Add(picture);

i'm not sure where you put images in your folder structure but you can find the path as bellow

 picture.ImageLocation = Path.Combine(System.Windows.Forms.Application.StartupPath, "Resources\Images\1.jpg");

Using Regular Expressions with JavaScript. A regular expression is a special text string for describing a search pattern, which is written in the form of /pattern/modifiers where "pattern" is the regular expression itself, and "modifiers" are a series of characters indicating various options.
         The character class is the most basic regex concept after a literal match. It makes one small sequence of characters match a larger set of characters. For example, [A-Z] could stand for the upper case alphabet, and \d could mean any digit.

From below example

• contains_alphaNumeric « It checks for string contains either letter or number (or) both letter and number. The hyphen (-) is ignored.
• onlyMixOfAlphaNumeric « It checks for string contain both letters and numbers only of any sequence order.

Example:

function matchExpression( str ) {
    var rgularExp = {
        contains_alphaNumeric : /^(?!-)(?!.*-)[A-Za-z0-9-]+(?<!-)$/,
        containsNumber : /\d+/,
        containsAlphabet : /[a-zA-Z]/,

        onlyLetters : /^[A-Za-z]+$/,
        onlyNumbers : /^[0-9]+$/,
        onlyMixOfAlphaNumeric : /^([0-9]+[a-zA-Z]+|[a-zA-Z]+[0-9]+)[0-9a-zA-Z]*$/
    }

    var expMatch = {};
    expMatch.containsNumber = rgularExp.containsNumber.test(str);
    expMatch.containsAlphabet = rgularExp.containsAlphabet.test(str);
    expMatch.alphaNumeric = rgularExp.contains_alphaNumeric.test(str);

    expMatch.onlyNumbers = rgularExp.onlyNumbers.test(str);
    expMatch.onlyLetters = rgularExp.onlyLetters.test(str);
    expMatch.mixOfAlphaNumeric = rgularExp.onlyMixOfAlphaNumeric.test(str);

    return expMatch;
}

// HTML Element attribute's[id, name] with dynamic values.
var id1 = "Yash", id2="777", id3= "Yash777", id4= "Yash777Image4"
    id11= "image5.64", id22= "55-5.6", id33= "image_Yash", id44= "image-Yash"
    id12= "_-.";
console.log( "Only Letters:\n ", matchExpression(id1) );
console.log( "Only Numbers:\n ", matchExpression(id2) );
console.log( "Only Mix of Letters and Numbers:\n ", matchExpression(id3) );
console.log( "Only Mix of Letters and Numbers:\n ", matchExpression(id4) );

console.log( "Mixed with Special symbols" );
console.log( "Letters and Numbers :\n ", matchExpression(id11) );
console.log( "Numbers [-]:\n ", matchExpression(id22) );
console.log( "Letters :\n ", matchExpression(id33) );
console.log( "Letters [-]:\n ", matchExpression(id44) );

console.log( "Only Special symbols :\n ", matchExpression(id12) );

Out put:

Only Letters:
  {containsNumber: false, containsAlphabet: true, alphaNumeric: true, onlyNumbers: false, onlyLetters: true, mixOfAlphaNumeric: false}
Only Numbers:
  {containsNumber: true, containsAlphabet: false, alphaNumeric: true, onlyNumbers: true, onlyLetters: false, mixOfAlphaNumeric: false}
Only Mix of Letters and Numbers:
  {containsNumber: true, containsAlphabet: true, alphaNumeric: true, onlyNumbers: false, onlyLetters: false, mixOfAlphaNumeric: true}
Only Mix of Letters and Numbers:
  {containsNumber: true, containsAlphabet: true, alphaNumeric: true, onlyNumbers: false, onlyLetters: false, mixOfAlphaNumeric: true}
Mixed with Special symbols
Letters and Numbers :
  {containsNumber: true, containsAlphabet: true, alphaNumeric: false, onlyNumbers: false, onlyLetters: false, mixOfAlphaNumeric: false}
Numbers [-]:
  {containsNumber: true, containsAlphabet: false, alphaNumeric: false, onlyNumbers: false, onlyLetters: false, mixOfAlphaNumeric: false}
Letters :
  {containsNumber: false, containsAlphabet: true, alphaNumeric: false, onlyNumbers: false, onlyLetters: false, mixOfAlphaNumeric: false}
Letters [-]:
  {containsNumber: false, containsAlphabet: true, alphaNumeric: true, onlyNumbers: false, onlyLetters: false, mixOfAlphaNumeric: false}
Only Special symbols :
  {containsNumber: false, containsAlphabet: false, alphaNumeric: false, onlyNumbers: false, onlyLetters: false, mixOfAlphaNumeric: false}

java Pattern Matching with Regular Expressions.

You can use gcc, in Terminal, by doing gcc -c tat.c -o tst

however, it doesn't come installed by default. You have to install the XCode package from tour install disc or download from http://developer.apple.com

Here is where to download past developer tools from, which includes XCode 3.1, 3.0, 2.5 ...

http://connect.apple.com/cgi-bin/WebObjects/MemberSite.woa/wo/5.1.17.2.1.3.3.1.0.1.1.0.3.3.3.3.1

1) Go to conf folder in tomcat installation directory

 e.g. C:\Tomcat 6.0\conf\

2) Edit following tag in server.xml file

<Connector connectionTimeout="20000" port="8080" protocol="HTTP/1.1" redirectPort="8443"/>

3) Change the port=8080 value to port=80

4) Save file.

5) Stop your Tomcat and restart it.

Just do String str = System.out.printf("%.2f", val).replace(",", "."); if you want to ensure that independently of the Locale of the user, you will always get / display a "." as decimal separator. This is a must if you don't want to make your program crash if you later do some kind of conversion like float f = Float.parseFloat(str);

Calendar.getInstance().get(Calendar.MONTH);

is zero based, 10 is November. From the javadoc;

public static final int MONTH Field number for get and set indicating the month. This is a calendar-specific value. The first month of the year in the Gregorian and Julian calendars is JANUARY which is 0; the last depends on the number of months in a year.

Calendar.getInstance().get(Calendar.JANUARY);

is not a sensible thing to do, the value for JANUARY is 0, which is the same as ERA, you are effectively calling;

Calendar.getInstance().get(Calendar.ERA);

If you are working with startsWith() and endsWith() then you have to be careful about leading spaces. Here is a complete example:

var str1 = " Your String Value Here.!! "; // Starts & ends with spaces    
if (str1.startsWith("Your")) { }  // returns FALSE due to the leading spaces…
if (str1.endsWith("Here.!!")) { } // returns FALSE due to trailing spaces…

var str2 = str1.trim(); // Removes all spaces (and other white-space) from start and end of `str1`.
if (str2.startsWith("Your")) { }  // returns TRUE
if (str2.endsWith("Here.!!")) { } // returns TRUE

Additionally to Eugene Retunsky's answer, quoting from $http documentation regarding the response:

The response object has these properties:

• data – {string|Object} – The response body transformed with the transform functions.

• status – {number} – HTTP status code of the response.

• headers – {function([headerName])} – Header getter function.

• config – {Object} – The configuration object that was used to generate the request.

• statusText – {string} – HTTP status text of the response.

Please note that the argument callback order for $resource (v1.6) is not the same as above:

Success callback is called with (value (Object|Array), responseHeaders (Function), status (number), statusText (string)) arguments, where the value is the populated resource instance or collection object. The error callback is called with (httpResponse) argument.

For concatenating selectors together when nesting, you need to use the parent selector (&):

.class {
    margin:20px;
    &:hover {
        color:yellow;
    }
}

In Laravel 5.1, I used: File: app\Providers\AppServiceProvider.php

public function boot()
{
    if ($this->isSecure()) {
        \URL::forceSchema('https');
    }
}

public function isSecure()
{
    $isSecure = false;
    if (isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == 'on') {
        $isSecure = true;
    } elseif (!empty($_SERVER['HTTP_X_FORWARDED_PROTO']) && $_SERVER['HTTP_X_FORWARDED_PROTO'] == 'https' || !empty($_SERVER['HTTP_X_FORWARDED_SSL']) && $_SERVER['HTTP_X_FORWARDED_SSL'] == 'on') {
        $isSecure = true;
    }

    return $isSecure;
}

NOTE: use forceSchema, NOT forceScheme

In JavaScript, the type of key/value store you are attempting to use is an object literal, rather than an array. You are mistakenly creating a composite array object, which happens to have other properties based on the key names you provided, but the array portion contains no elements.

Instead, declare valueToPush as an object and push that onto cookie_value_add:

// Create valueToPush as an object {} rather than an array []
var valueToPush = {};

// Add the properties to your object
// Note, you could also use the valueToPush["productID"] syntax you had
// above, but this is a more object-like syntax
valueToPush.productID = productID;
valueToPush.itemColorTitle = itemColorTitle;
valueToPush.itemColorPath = itemColorPath;

cookie_value_add.push(valueToPush);

// View the structure of cookie_value_add
console.dir(cookie_value_add);

The path can either be full or relative (of course if the image is from another domain it must be full).

You don't need to use quotes in the URI; the syntax can either be:

background-image: url(image.jpg);

Or

background-image: url("image.jpg");

However, from W3:

Some characters appearing in an unquoted URI, such as parentheses, white space characters, single quotes (') and double quotes ("), must be escaped with a backslash so that the resulting URI value is a URI token: '\(', '\)'.

So in instances such as these it is either necessary to use quotes or double quotes, or escape the characters.

You could also connect with flag

-o ServerAliveInterval=<secs>

Now that you have provided your HTML sample, we're able to see that your XPath is slightly wrong. While it's valid XPath, it's logically wrong.

You've got:

//*[contains(@id, 'ctl00_btnAircraftMapCell')]//*[contains(@title, 'Select Seat')]

Which translates into:

Get me all the elements that have an ID that contains ctl00_btnAircraftMapCell. Out of these elements, get any child elements that have a title that contains Select Seat.

What you actually want is:

//a[contains(@id, 'ctl00_btnAircraftMapCell') and contains(@title, 'Select Seat')]

Which translates into:

Get me all the anchor elements that have both: an id that contains ctl00_btnAircraftMapCell and a title that contains Select Seat.

Simply look at:

http://download.oracle.com/javase/6/docs/api/java/math/BigDecimal.html#ROUND_HALF_UP

and:

setScale(int precision, int roundingMode)

Or if using Java 6, then

http://download.oracle.com/javase/6/docs/api/java/math/RoundingMode.html#HALF_UP

http://download.oracle.com/javase/6/docs/api/java/math/MathContext.html

and either:

setScale(int precision, RoundingMode mode);
round(MathContext mc);

If you want to execute a local script remotely without saving that script remotely you can do it like this:

cat local_script.sh | ssh user@remotehost 'bash -'

It works like a charm for me.

I do that even from Windows to Linux given that you have MSYS installed on your Windows computer.

In my case (after renaming application namespace manually) I had to reselect the Startup object in Project properties.

Running assembly Code on Mac is just 3 steps away from you. It could be done using XCODE but better is to use NASM Command Line Tool. For My Ease I have already installed Xcode, if you have Xcode installed its good.

But You can do it without XCode as well.

Just Follow:

1. First Install NASM using Homebrew brew install nasm
2. convert .asm file into Obj File using this command nasm -f macho64 myFile.asm
3. Run Obj File to see OutPut using command ld -macosx_version_min 10.7.0 -lSystem -o OutPutFile myFile.o && ./64

Simple Text File named myFile.asm is written below for your convenience.

.len:   equ     $ - msg

{{ $post->created_at }}

will return '2014-06-26 04:07:31'

The solution is

{{ $post->created_at->format('Y-m-d') }}

I was also getting the same error I checked it my system was in 64 bit and I was using oracle.DataAccess of 32 bit version I added correct 64 version now it got resolved below path for the ref of Oracle.DataAccess.dll

Correct path for 64 bit OS- C:\Oracle\11g_64\product\11.2.0\client_64\odp.net\bin\4\Oracle.DataAccess.dll

Correct path for 32 bit OS- C:\Oracle\11g_32\product\11.2.0\client_64\odp.net\bin\4\Oracle.DataAccess.dll

Here is a well tested function which i used for my projects with detailed self explanatory comments

There are many times when the ports other than 80 are blocked by server firewall so the code appears to be working fine on localhost but not on the server

function get_page($url){

global $proxy;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
//curl_setopt($ch, CURLOPT_PROXY, $proxy);
curl_setopt($ch, CURLOPT_HEADER, 0); // return headers 0 no 1 yes
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // return page 1:yes
curl_setopt($ch, CURLOPT_TIMEOUT, 200); // http request timeout 20 seconds
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); // Follow redirects, need this if the url changes
curl_setopt($ch, CURLOPT_MAXREDIRS, 2); //if http server gives redirection responce
curl_setopt($ch, CURLOPT_USERAGENT,
    "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.7) Gecko/20070914 Firefox/2.0.0.7");
curl_setopt($ch, CURLOPT_COOKIEJAR, "cookies.txt"); // cookies storage / here the changes have been made
curl_setopt($ch, CURLOPT_COOKIEFILE, "cookies.txt");
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); // false for https
curl_setopt($ch, CURLOPT_ENCODING, "gzip"); // the page encoding

$data = curl_exec($ch); // execute the http request
curl_close($ch); // close the connection
return $data;
}

There is a solution to this if you really need a static access to the current context. In Startup.Configure(….)

app.Use(async (httpContext, next) =>
{
    CallContext.LogicalSetData("CurrentContextKey", httpContext);
    try
    {
        await next();
    }
    finally
    {
        CallContext.FreeNamedDataSlot("CurrentContextKey");
    }
});

And when you need it you can get it with :

HttpContext context = CallContext.LogicalGetData("CurrentContextKey") as HttpContext;

I hope that helps. Keep in mind this workaround is when you don’t have a choice. The best practice is to use de dependency injection.

I always prefer pure SQL so :

SELECT 'ALTER TABLE [' + l.schema_n + '].[' 
       + l.table_name + '] ALTER COLUMN [' 
       + l.column_name + '] ' + l.data_type + '(' 
       + Cast(l.new_max_length AS NVARCHAR(100)) 
       + ') COLLATE ' + l.dest_collation_name + ';', 
       l.schema_n, 
       l.table_name, 
       l.column_name, 
       l.data_type, 
       l.max_length, 
       l.collation_name 
FROM   (SELECT Row_number() 
                 OVER ( 
                   ORDER BY c.column_id) AS row_id, 
               Schema_name(o.schema_id)  schema_n, 
               ta.NAME                   table_name, 
               c.NAME                    column_name, 
               t.NAME                    data_type, 
               c.max_length, 
               CASE 
                 WHEN c.max_length = -1 
                       OR ( c.max_length > 4000 ) THEN 4000 
                 ELSE c.max_length 
               END                       new_max_length, 
               c.column_id, 
               c.collation_name, 
               'French_CI_AS'            dest_collation_name 
        FROM   sys.columns c 
               INNER JOIN sys.tables ta 
                       ON c.object_id = ta.object_id 
               INNER JOIN sys.objects o 
                       ON c.object_id = o.object_id 
               JOIN sys.types t 
                 ON c.system_type_id = t.system_type_id 
               LEFT OUTER JOIN sys.index_columns ic 
                            ON ic.object_id = c.object_id 
                               AND ic.column_id = c.column_id 
               LEFT OUTER JOIN sys.indexes i 
                            ON ic.object_id = i.object_id 
                               AND ic.index_id = i.index_id 
        WHERE  1 = 1 
               AND c.collation_name = 'SQL_Latin1_General_CP1_CI_AS' 
       --'French_CI_AS'-- ALTER DONE YET OLD VALUE :'SQL_Latin1_General_CP1_CI_AS' 
       ) l 
ORDER  BY l.column_id;

One more way to accomplish it will be as shown below. Here, we use Enumerable#each_with_object to collect values, and make use of Object#tap to get rid of temporary variable that is otherwise needed for nil check on result of process_x method.

items.each_with_object([]) {|x, obj| (process x).tap {|r| obj << r unless r.nil?}}

Complete example for illustration:

items = [1,2,3,4,5]
def process x
    rand(10) > 5 ? nil : x
end

items.each_with_object([]) {|x, obj| (process x).tap {|r| obj << r unless r.nil?}}

Alternate approach:

By looking at the method you are calling process_x url, it is not clear what is the purpose of input x in that method. If I assume that you are going to process the value of x by passing it some url and determine which of the xs really get processed into valid non-nil results - then, may be Enumerabble.group_by is a better option than Enumerable#map.

h = items.group_by {|x| (process x).nil? ? "Bad" : "Good"}
#=> {"Bad"=>[1, 2], "Good"=>[3, 4, 5]}

h["Good"]
#=> [3,4,5]

I think you should use python wheels for distribution instead of egg now.

Wheels are the new standard of python distribution and are intended to replace eggs. Support is offered in pip >= 1.4 and setuptools >= 0.8.

$memberId =$_SESSION['TWILLO']['Id'];

    $QueryServer=mysql_query("select * from smtp_server where memberId='".$memberId."'");
    $data = array();
    while($ser=mysql_fetch_assoc($QueryServer))
    {

     $data[$ser['Id']] =array('ServerName','ServerPort','Server_limit','email','password','status');

    }

If you use Python3x then string is not the same type as for Python 2.x, you must cast it to bytes (encode it).

plaintext = input("Please enter the text you want to compress")
filename = input("Please enter the desired filename")
with gzip.open(filename + ".gz", "wb") as outfile:
    outfile.write(bytes(plaintext, 'UTF-8'))

Also do not use variable names like string or file while those are names of module or function.

EDIT @Tom

Yes, non-ASCII text is also compressed/decompressed. I use Polish letters with UTF-8 encoding:

plaintext = 'Polish text: acelnószzACELNÓSZZ'
filename = 'foo.gz'
with gzip.open(filename, 'wb') as outfile:
    outfile.write(bytes(plaintext, 'UTF-8'))
with gzip.open(filename, 'r') as infile:
    outfile_content = infile.read().decode('UTF-8')
print(outfile_content)

Darcula

UPDATE 2016-02: NetBeans 8 now has a Darcula plugin, better and more complete than the alternatives discussed in old version of this Answer.

The attractive and productive Darcula theme in JetBrains IntelliJ is now available in NetBeans 8.0 & 8.1!

The Real Thing

This plugin provides the real Darcula, not an imitation.

Konstantin Bulenkov of the JetBrains company open-sourced the Darcula look-and-feel originally built for the IntelliJ IDE. This NetBeans plugin discussed here wraps that original implementation, adapting it to NetBeans. So we see close fidelity to the original Darcula. [By the way, there are many other reasons beyond Darcula to use IntelliJ – both IntelliJ and NetBeans are truly excellent and amazing products.]

This NetBeans plugin is itself open-source as well.

Installation

Comes in two parts:

• A plugin
• A Fonts & Colors profile

Plugin

The plugin Darcula LAF for NetBeans is easily available through the usual directory within NetBeans.

Choose Tools > Plugins. On the Available Plugins tab, scroll or search for "Darcula LAF for NetBeans". As per usual, check the checkbox and click the Install button. Restart NetBeans.

Profile

1. In NetBeans > Preferences > Fonts & Colors (tab) > Profile (popup menu), choose the new Darcula item.
2. Click the Apply button.

I suggest also hitting Duplicate in case you ever make any modifications (discussed below).

Fix overly-bright background colors

You may find the background color of lines of code may be too bright such as lines marked with a breakpoint, or the currently executing line in the debugger. These are categories listed on the Annotations tab of the Fonts & Colors tab.

Of course you can change the background color of each Category manually but that is tedious.

Workaround: Click the Restore button found to the right of the Profile name. Double-check to make sure you have Darcula as the selected Profile of course. Then click the Apply and OK buttons at the bottom.

Font

You may want to change the font in the method editor. I most highly recommend the commercial font for programmers, PragmataPro. For a free-of-cost and open-source font, the best is Hack. Hack was built on the very successful DejaVu font which in turn was built on Bitstream Vera.

To change the font, add these steps to the above to duplicate the profile as a backup before making your modification:

3. Click the Duplicate button.
4. Save the duplicate with a different name such as appending your name.
   Example: “Darcula - Juliette”.
5. Click the Apply button.

While in that same Fonts & Colors tab, select Default in the Category list and hit the … button to choose a font.

You might also want to change the font seen in the Output and the Terminal panes. From that Fonts & Colors tab, switch to the sibling tab Miscellaneous. Then see both the Output tab and the Terminal tab.

Experience So Far

While still new I am reserving final judgement on Darcula. So far, so good. Already the makers have had a few updates fixing a few glitches, so that is good to see. This seems to be a very thorough product. As a plugin this affects the entire user interface of NetBeans; that can be very tricky to get right.

There was a similar plugin product predating Darcula: the “Dark Look And Feel Themes” plugin. While I was grateful to use that for a while, I am much happier with Darcula. That other one was more clunky and I had to spend much time tweaking colors of “Norway Today” to work together. Also, that plugin was not savvy with Mac OS X menus so the main Mac menu bar was nearly empty while NetBeans’ own menu bar was embedded within the window. The Darcula plugin has no such problem; the Mac menu bar appears normally.

The rest of this Answer is left intact for history, and for alternatives if Darcula proves problematic.

NetBeans 8 – Dark Editor

At least in NetBeans 8.0, two dark profiles are now built-in. Profile names:

• Norway Today
• City Lights

The profiles affect only the code editing pane, not the entire NetBeans user-interface. That should mean much less risk of side-effects and bugs than a plugin.

Norway Today

City Lights

Tip: You can alter the font in either theme, while preserving the other aspects. Perhaps Menlo on a Mac, or its parent DejaVu. Or my fav, the commercial font Pragmata.

Unfortunately, neither theme suits my eyes. They do not begin to compare to the excellent Darcula theme in JetBrains IntelliJ.

Choose Profile in Font Settings

On a Mac, the menu path is Netbeans > Preferences > Fonts & Colors (tab) > Profile (popup menu).

On other host operating systems, the menu path may be Tools > Options > Fonts & Colors. Not sure, but it was so in previous versions.

To summarize the other answers, in <jre-path>/lib/security/java.security you can set the value of the property networkaddress.cache.ttl to adjust how DNS lookups are cached. Note that this is not a system property but a security property. I was able to set this using:

java.security.Security.setProperty("networkaddress.cache.ttl", "<value>");

This can also be set by the system property -Dsun.net.inetaddr.ttl though this will not override a security property if it is set elsewhere.

I would also like to add that if you are seeing this issue with web services in WebSphere, as I was, setting networkaddress.cache.ttl will not be enough. You need to set the system property disableWSAddressCaching to true. Unlike the time-to-live property, this can be set as a JVM argument or via System.setProperty).

IBM has a pretty detailed post on how WebSphere handles DNS caching here. The relevant piece to the above is:

To disable address caching for Web services, you need to set an additional JVM custom property disableWSAddressCaching to true. Use this property to disable address caching for Web services. If your system typically runs with lots of client threads, and you encounter lock contention on the wsAddrCache cache, you can set this custom property to true, to prevent caching of the Web services data.

As of June 2020, adding role='button' to any HTML tag would add cursor: "pointer" to the element styling.

<span role="button">Non-button element button</span>

IE trick for dynamic forms:

$('#someform').find('input,select,textarea').serialize();

To add more information to the correct answer above, after reading an example from Android-er I found you can easily convert your preference activity into a preference fragment. If you have the following activity:

public class MyPreferenceActivity extends PreferenceActivity
{
    @Override
    protected void onCreate(final Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        addPreferencesFromResource(R.xml.my_preference_screen);
    }
}

The only changes you have to make is to create an internal fragment class, move the addPreferencesFromResources() into the fragment, and invoke the fragment from the activity, like this:

public class MyPreferenceActivity extends PreferenceActivity
{
    @Override
    protected void onCreate(final Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        getFragmentManager().beginTransaction().replace(android.R.id.content, new MyPreferenceFragment()).commit();
    }

    public static class MyPreferenceFragment extends PreferenceFragment
    {
        @Override
        public void onCreate(final Bundle savedInstanceState)
        {
            super.onCreate(savedInstanceState);
            addPreferencesFromResource(R.xml.my_preference_screen);
        }
    }
}

There may be other subtleties to making more complex preferences from fragments; if so, I hope someone notes them here.

Minizip does have an example programs to demonstrate its usage - the files are called minizip.c and miniunz.c.

Update: I had a few minutes so I whipped up this quick, bare bones example for you. It's very smelly C, and I wouldn't use it without major improvements. Hopefully it's enough to get you going for now.

I built and tested it with MinGW/MSYS on Windows like this:

I had to switch from Eclipse Oxygen that I got from IBM and used IBM JDK 8 to Eclipse Photon and Oracle JDK 8. I'm working on Java customizations for maximo.

$scope.olkes = [{'id':11, 'name':'---Z?hm?t olmasa seçim edin---'},
                {'id':15, 'name':'Türky?'},
                {'id':45, 'name':'Az?rbaycan'},
                {'id':60, 'name':'Rusya'},
                {'id':64, 'name':'Gürcüstan'},
                {'id':65, 'name':'Qazaxistan'}];

<span>{{(olkes | filter: {id:45})[0].name}}</span>

output: Az?rbaycan

Some additional steps may be needed to set both the project and default workspace JRE correctly, as MayoMan mentioned. Here is the complete sequence in Eclipse Luna:

• Right click your project > properties
• Select “Java Build Path” on left, then “JRE System Library”, click Edit…
• Select "Workspace Default JRE"
• Click "Installed JREs"
• If you see JRE you want in the list select it (selecting a JDK is OK too)
• If not, click Search…, navigate to Computer > Windows C: > Program Files > Java, then click OK
• Now you should see all installed JREs, select the one you want
• Click OK/Finish a million times

Easy.... not.

The easiest solution I found was to specify excel version 97-2003 on the connection manager setup.

Missing implementation of a function in class

The reason I faced this issue was because I had deleted the function's implementation from the cpp file, but forgotten to delete the declaration from the .h file.

My answer doesn't specifically answer your question, but lets people who come to this thread looking for answer know that this can also one cause.

For Mac users in the 17.06.0-ce-mac19 version you can simply move the Disk Image location from the user interface in the preferences option Just change the location of the disk image and it will work (by clicking Move disk Image) and restarting the docker. Using this approach I was able to use my external hardisk for storing docker images.

Although the above answers mostly get them right, there is one slight issue with them all.. Follow these steps and you are good to go

1. Right click on This PC -> Properties
2. On the left pane select "Advanced System Settings"
3. On the new window select -> Advanced tab
4. Click on the "Environment Variables" button
5. On the first top section click on the "New" button

set variable name -> ANDROID_HOME

set variable value -> the custom location of the Android SDK

6. Now click on the newly created variable name and in the box below select "Path" and click on the Edit button
7. Now click on New and paste the location of the "platform-tools"
8. Again click on New and paste the location of the "tools" You can find the locations of the above platform-tools and tools - they are generally inside the Android SDK folder
9. MOST IMPORTANT OF ALL...

   save all those by clicking ok If you are using the terminal(cmd) close it and open it again

This code will add an event listener to the default local Inbox, then take some action on incoming emails. You need to add that action in the code below.

Private WithEvents Items As Outlook.Items 
Private Sub Application_Startup() 
  Dim olApp As Outlook.Application 
  Dim objNS As Outlook.NameSpace 
  Set olApp = Outlook.Application 
  Set objNS = olApp.GetNamespace("MAPI") 
  ' default local Inbox
  Set Items = objNS.GetDefaultFolder(olFolderInbox).Items 
End Sub
Private Sub Items_ItemAdd(ByVal item As Object) 

  On Error Goto ErrorHandler 
  Dim Msg As Outlook.MailItem 
  If TypeName(item) = "MailItem" Then
    Set Msg = item 
    ' ******************
    ' do something here
    ' ******************
  End If
ProgramExit: 
  Exit Sub
ErrorHandler: 
  MsgBox Err.Number & " - " & Err.Description 
  Resume ProgramExit 
End Sub

After pasting the code in ThisOutlookSession module, you must restart Outlook.

You can do this via local storage API. Note that this works only between 2 tabs. you can't put both sender and receiver on the same page:

On sender page:

localStorage.setItem("someKey", "someValue");

On the receiver page

    $(document).ready(function () {

        window.addEventListener('storage', storageEventHandler, false);

        function storageEventHandler(evt) {
            alert("storage event called key: " + evt.key);
        }
    });

<% %> and <%- and -%> are for any Ruby code, but doesn't output the results (e.g. if statements). the two are the same.

<%= %> is for outputting the results of Ruby code

<%# %> is an ERB comment

Here's a good guide: http://api.rubyonrails.org/classes/ActionView/Base.html

Got better solution:

$('#element').resizable({
    stop: function( event, ui ) {
        $('#element').height(ui.originalSize.height);
    }
});

Set cache: false in jQuery.get call using Below Method

use new Date().getTime(), which will avoid collisions unless you have multiple requests happening within the same millisecond.

Or

The following will prevent all future AJAX requests from being cached, regardless of which jQuery method you use ($.get, $.ajax, etc.)

$.ajaxSetup({ cache: false });

If you need some es6 improvements not supported by Typescript, you can target es6 in your tsconfig and use Babel to convert your files in es5.

I did a time test here, using each method 100000 times in a loop. The results surprised me. (The results still surprise me after editing them in response to valid criticism in the comments.)

Here's the script:

import timeit

bad_chars = '(){}<>'

setup = """import re
import string
s = 'Barack (of Washington)'
bad_chars = '(){}<>'
rgx = re.compile('[%s]' % bad_chars)"""

timer = timeit.Timer('o = "".join(c for c in s if c not in bad_chars)', setup=setup)
print "List comprehension: ",  timer.timeit(100000)


timer = timeit.Timer("o= rgx.sub('', s)", setup=setup)
print "Regular expression: ", timer.timeit(100000)

timer = timeit.Timer('for c in bad_chars: s = s.replace(c, "")', setup=setup)
print "Replace in loop: ", timer.timeit(100000)

timer = timeit.Timer('s.translate(string.maketrans("", "", ), bad_chars)', setup=setup)
print "string.translate: ", timer.timeit(100000)

Here are the results:

List comprehension:  0.631745100021
Regular expression:  0.155561923981
Replace in loop:  0.235936164856
string.translate:  0.0965719223022

Results on other runs follow a similar pattern. If speed is not the primary concern, however, I still think string.translate is not the most readable; the other three are more obvious, though slower to varying degrees.

I solved this using multer as suggested above, but they missed giving a full working example, on how to do this. Basically this can happen when you have a form group with enctype="multipart/form-data". Here's the HTML for the form I had:

<form action="/stats" enctype="multipart/form-data" method="post">
  <div class="form-group">
    <input type="file" class="form-control-file" name="uploaded_file">
    <input type="text" class="form-control" placeholder="Number of speakers" name="nspeakers">
    <input type="submit" value="Get me the stats!" class="btn btn-default">            
  </div>
</form>

And here's how to use multer to get the values and names of this form with Express.js and node.js:

var multer  = require('multer')
var upload = multer({ dest: './public/data/uploads/' })
app.post('/stats', upload.single('uploaded_file'), function (req, res) {
   // req.file is the name of your file in the form above, here 'uploaded_file'
   // req.body will hold the text fields, if there were any 
   console.log(req.file, req.body)
});

Well, I've got no problem here :

df <- data.frame(v=1:5, x=sample(LETTERS[1:5],5))
df

#   v x
# 1 1 D
# 2 2 A
# 3 3 B
# 4 4 C
# 5 5 E

df <- df[order(df$x),]
df

#   v x
# 2 2 A
# 3 3 B
# 4 4 C
# 1 1 D
# 5 5 E

As Brad Wilson states in his answer here:

ModelState.IsValid tells you if any model errors have been added to ModelState.

The default model binder will add some errors for basic type conversion issues (for example, passing a non-number for something which is an "int"). You can populate ModelState more fully based on whatever validation system you're using.

Try using :-

if (!ModelState.IsValid)
{
    var errors = ModelState.SelectMany(x => x.Value.Errors.Select(z => z.Exception));

    // Breakpoint, Log or examine the list with Exceptions.
}

If it helps catching you the error. Courtesy this and this

I may have not got your answer correct, but you can try this:

public void MusicController(View view) throws IOException{
    switch (view.getId()){
        case R.id.play: mplayer.start();break;
        case R.id.pause: mplayer.pause(); break;
        case R.id.stop:
            if(mplayer.isPlaying()) {
                mplayer.stop();
                mplayer.prepare(); 
            }
            break;

    }// where mplayer is defined in  onCreate method}

as there is just one thread handling all, so stop() makes it die so we have to again prepare it If your intent is to start it again when your press start button(it throws IO Exception) Or for better understanding of MediaPlayer you can refer to Android Media Player

use this..

$(".content_box a:not('.button')")

you can do:

<div style="float: left;"></div>

or

<div style="display: inline;"></div>

Either one will cause the divs to tile horizontally.

I know its old question, but I am trying this with $gte and $size in find. I think to find() is faster.

db.getCollection('collectionName').find({ name : { $gte : {  $size : 1 } }})

Another way to make objects in Javascript using JQuery, getting data from the dom and pass it to the object Box and, for example, store them in an array of Boxes, could be:

var box = {}; // my object
var boxes =  []; // my array

$('div.test').each(function (index, value) {
    color = $('p', this).attr('color');
    box = {
        _color: color // being _color a property of `box`
    }
    boxes.push(box);
});

Hope it helps!

For readability, I restructured the query... starting with the apparent top-most level being Table1, which then ties to Table3, and then table3 ties to table2. Much easier to follow if you follow the chain of relationships.

Now, to answer your question. You are getting a large count as the result of a Cartesian product. For each record in Table1 that matches in Table3 you will have X * Y. Then, for each match between table3 and Table2 will have the same impact... Y * Z... So your result for just one possible ID in table 1 can have X * Y * Z records.

This is based on not knowing how the normalization or content is for your tables... if the key is a PRIMARY key or not..

Ex:
Table 1       
DiffKey    Other Val
1          X
1          Y
1          Z

Table 3
DiffKey   Key    Key2  Tbl3 Other
1         2      6     V
1         2      6     X
1         2      6     Y
1         2      6     Z

Table 2
Key    Key2   Other Val
2      6      a
2      6      b
2      6      c
2      6      d
2      6      e

So, Table 1 joining to Table 3 will result (in this scenario) with 12 records (each in 1 joined with each in 3). Then, all that again times each matched record in table 2 (5 records)... total of 60 ( 3 tbl1 * 4 tbl3 * 5 tbl2 )count would be returned.

So, now, take that and expand based on your 1000's of records and you see how a messed-up structure could choke a cow (so-to-speak) and kill performance.

SELECT
      COUNT(*)
   FROM
      Table1 
         INNER JOIN Table3
            ON Table1.DifferentKey = Table3.DifferentKey
            INNER JOIN Table2
               ON Table3.Key =Table2.Key
               AND Table3.Key2 = Table2.Key2 

The first guy with a public class makes a lot more sense. The original guy has multiple forms and if global variables are needed then the global class will be better. Think of someone coding behind him and needs to use a global variable in a class you have IntelliSense, it will also make coding a modification 6 months later a lot easier.

Also if I have a brain fart and use like in an example parts on a module level then want my global parts I can do something like

Dim Parts as Integer
parts = 3
GlobalVariables.parts += Parts  '< Not recommended but it works

At least that's why I would go the class route.

You haven't mentioned the Initial catalog name in the connection string. Give your database name as Initial Catalog name.

<add name ="AutoRepairSqlProvider" connectionString=
     "Data Source=.\SQLEXPRESS; Initial Catalog=MyDatabase; AttachDbFilename=|DataDirectory|\AutoRepairDatabase.mdf;
     Integrated Security=True;User Instance=True"/>

If you setWantsLayer to YES first, you can directly manipulate the layer background.

[self.view setWantsLayer:YES];
[self.view.layer setBackgroundColor:[[NSColor whiteColor] CGColor]];

I'd just experienced something slightly different, because I work on my own library (WM_GSRecognizerLib), but the error is the same.

What'd happen: due to some updates, the path targeting the lib to include (.a) was from the "Debug-iphoneos" folder (where it is generated). Compiling for Generic iOS Devices worked fine, but not for simulator, complaining for the missing i386 architecture.

What I did for this issue, is to also include the binaries from the "Debug-iphonesimulator" folder.

It can help for this topic, because the explanation is here: devices require binaries for arm64/armv7/armv7s, while simulator does need i386.

There is no float: center; in css. Use margin: 0 auto; instead. So like this:

.mydivclass {
    margin: 0 auto;
 }

As I found the default Bootstrap <hr/> size unsightly, here's some simple HTML and CSS to balance out the element visually:

HTML:

<hr class="half-rule"/>

CSS:

.half-rule { 
    margin-left: 0;
    text-align: left;
    width: 50%;
 }

From the documentation:

Cmd] and Cmd[ navigates among split panes in order of use.

We have just been going through this same issue, but the other way around. That is, we store dollar amounts as DECIMAL, but now we're finding that, for example, MySQL was calculating a value of 4.389999999993, but when storing this into the DECIMAL field, it was storing it as 4.38 instead of 4.39 like we wanted it to. So, though DOUBLE may cause rounding issues, it seems that DECIMAL can cause some truncating issues as well.

CONVERT(DateTime, ExpireDate, 121) AS ExpireDate

will do what is needed, result:

2012-04-24 00:00:00.000

INADDR_ANY instructs listening socket to bind to all available interfaces. It's the same as trying to bind to inet_addr("0.0.0.0"). For completeness I'll also mention that there is also IN6ADDR_ANY_INIT for IPv6 and it's the same as trying to bind to :: address for IPv6 socket.

#include <netinet/in.h>

struct in6_addr addr = IN6ADDR_ANY_INIT;

Also, note that when you bind IPv6 socket to to IN6ADDR_ANY_INIT your socket will bind to all IPv6 interfaces, and should be able to accept connections from IPv4 clients as well (though IPv6-mapped addresses).

As per W3C: DOM permits programs and scripts to dynamically access and update the content, structure and style of XML or HTML documents.

DOM is composed of:

• set of objects/elements
• a structure of how these objects/elements can be combined
• and an interface to access and modify them

cheers

I had the same issue, for me this fixed the issue:
right click on the project ->maven -> update project

Since you are using jQuery you can use this onClick handler which calls click:

$("#datepicker").click()

This is the same as $("#datepicker").trigger("click").

For a jQuery-free version check out this answer on SO.

If you want HTML, with images and a list, this isn't support by UILabel. However, I've found YYText does the trick.
